(2010) Popoola, B.O.; Denloye, O.O.; Ajayi, D.M.; Sote, E.O.
caries is the most effective means of ensuring resolution of the condition and its sequelae. The aim of this study was to compare the effectiveness of clinical and radiographic (using bitewing radiograph) methods of caries diagnosis in children. The subjects were 172 children within the age range of 5-12 years attending the Paedodontic Clinic of the University College Hospital for the first time. They were clinically examined for the presence of dental caries using the WHO criteria. Left and right bitewing radiographs were taken following the clinical examination to detect dental caries. Clinical examination found additional 4 occlusal caries (incipient caries) that were not diagnosed radiographically and radiographic examination revealed additional 20 approximal surface caries that were not evident clinically in deciduous teeth. In permanent teeth, 3 additional occlusal caries were diagnosed clinically while only one additional approximal caries was diagnosed radiographically. These observations revealed the additional diagnostic value of bitewing radiograph in the diagnosis of approximal caries in children and the importance of clinical examinations in diagnosis of early occlusal caries (incipient caries) which are difficult to see on dental radiographs. In view of these findings, the use of bitewing radiographs combined with careful clinical examination will be of great advantage in early detection of caries in children
Awareness of dental diseases and oral health behaviour among dental and medical students of a Nigerian university
(2016) Abiodun-Solanke,I.M.F.,; Opeodu, O.I.; Ajayi, D.M.
Aim of the study. To assess the effects of change in curriculum on the oral health knowledge and behaviour among the third and fourth year medical and dental students, and their use of dental services. Methods. A self-administered questionnaire was used to assess, among other things, the knowledge of respondents of dental diseases and possible risk factors. Results. Two hundred and thirty-seven respondents filled and returned the questionnaires, out of which 125 (52.7%) were females (with male:female ratio of 1:1.1). About 50% of the respondents were in 300 levels, consisting of 99 (82.5%) medical students. A higher percentage of 300 level medical students have better knowledge of diseases such as pulpitis, oral cancer and scurvy as possibly occurring within the mouth than their 400 level counterparts. Conclusions. There is a need not only to integrate dentistry into the curriculum of medical students, but also to re-assess constantly the impact of such on the quality of output from various medical schools.
Burden of Undergraduate Dental Training in Nigeria
(2014) Abiodun-Solanke, I.F.; Ajayi, D.M.; Dosumu,O.O.
Background: Training of dental students at all levels has been found to be far more expensive than what is required to train their medical counterparts. The extra cost is expected to be provided by the prospective students of which they are usually unaware of at the point of admission. Objectives: This study was designed to assess the sociodemographic status of dental students in Nigerian Universities as well as factors affecting the amount a dental student spent buying required instruments and other materials needed for their clinical training. Methods: A self-administered questionnaire which was a modified version of that used in Canada and United State to investigate students financial issues was used in this study. The modified structured questionnaire was sent to . the clinical (400-600levels) students in the oldest and well established dental schools in Nigeria. Results: The age range of participants was 19 to 36 years with a mean age of 25±2.7years; 57.3% were males, while 42.7% were females. More than a third (38.2%) of the respondents fathers were in the high class, while 42.2% of the respondents mothers belonged to the middle class. About forty five percent of the total respondents admitted to have spent greater than N30.000 buying their hand instruments out of whom 61.3% belonged to the middle socioeconomic class. The relationship between the amount spent in -purchasing instruments and the socioeconomic status was statistically significant (p=0.001). About half of the respondents admitted they had no idea of extra cost required for their clinical training. Conclusion: The financial burden for undergraduate dental training in Nigeria include tuition, costs of expensive dental textbooks, instruments and other consumables which many students were not aware of by the time they entered the program.
Causes and pattern of fracture of acrylic dentures among patients seen in a Nigerian teaching hospital
(2007) Ogunrinde,T.J.; Ajayi, D.M.; Dosunmu, O.O
There is little information on the causes and pattern o f fracture of acrylic dentures in Nigerian patients despite being the most frequently employed design in Nigeria. The aim of this study was to determine the average life span o f acrylic dentures before fracture, the causes and pattern of fracture o f acrylic dentures in a Nigerian population. A ll consecutive patients that presented with fractured acrylic dentures at the Dental Centre, University College Hospital, Ibadan between January and July 2006 and were willing to participate were recruited into the study. A structured interviewer-administered questionnaire was used to record data from the patients. The questionnaire focused on patients’ demographic data, age of acrylic denture as at the time of fracture, causes and pattern o f fractures. The data were analysed using SPSS Version 11. A total of sixty-two patients were included in the study. They presented with sixty-nine fractured dentures. Five were complete dentures while 64 were partial dentures. The average life span was 7.4years ± 6.6 (SD) years. Early fracture was seen in 9 (13.4%), intermediate fracture in 29 (42%), and late fracture in 3 1 (44.9%) cases. The commonest cause o f fracture was mastication as seen in 30.4% of the cases while the least cause was fight (4.3%). The commonest site of fracture (34.8%) was the palatal plate around the crest o f the edentulous ridge while fracture of wrought metal clasps was the least, occurring in 1.4% o f cases'. We recommend proper design with balanced articulation and more emphasis on compliance to post insertion instructions by patients to prevent early fracture of acrylic dentures. Also, reinforcing the acrylic denture base especially in stress bearing area may prolong the life span of these prostheses.
Dental anxiety: investigative and management techniques often employed in a cross section of Nigerian Specialist Dental Clinics
(2009) Arigbede, A.O.; Ajayi, D.M.; Adeyemi, B.F.
Background: Information on the pattern of dental anxiety’ management in Nigeria is currendy not available. Aim: The study was designed to determine the awareness and frequency of application of dental anxiety assessment questionnaires as well as the current pattern in the management of dental anxiety’ in Nigeria. Methods: The cross-sectional study was conducted using structured questionnaires distributed among dental residents and house officers in Nigerian dental schools. Information requested included demographic variables, frequency of presentation of dental anxiety’, awareness and frequency of application of dental anxiety' questionnaires. The respondents were also asked to rate the frequency of application of the outlined dental anxiety’ management techniques on a 5-point Likert scale. The median score and the range for each technique was determined and compared between the male and female respondents. Results: A total of 96 questionaires were sent out to dental surgeons of all grades. Response was obtained from 86 giving a response rate of 90%. Only 23 (26.7%) respondents were aware of dental anxiety’ questionnaires while only 13 (15.1%) have seen the instrument applied. The percentage of patients with dental anxiety’ was estimated by the respondents to be <20%. Behaviour therapy was the most frequently employed dental anxiety management technique. The female respondents employ behaviour therapy and intramuscular sedation more frequently. Conclusion: The awareness and frequency of application of dental anxiety’ questionnaires appeared poor. Behaviour therapy was the most frequently employed dental anxiety’ management technique. It appears the female respondents employ behavior therapy and intramuscular sedation more frequently.
Dental Fluorosis and its Indices, what’s new?
(2014) Abiodun-Solanke, I.M.F.; Ajayi, D.M.
Since the description of dental fluorosis as a disease entity by Fredrick McKay and GV Black in 1916, several indices have been used to categorize the different forms of dental fluorosis. Such indices include Dean’s, Thylstrup and Fejerskov’s(T-F), Total Surface Index of Fluorosis(TSIF) etc. However, none of these indices that was introduced in the 20th century is without shortcomings or limitations, which eventually led to the discovery of newer indices with continuous scale such as the Visual Analogue scale, Quantitative Light Fluorescence and Polarized white lightimages .
Effect of resilient lining of obturator bulbs on patients with maxillectomies
(2016) Ikusika, O.F.; Dosumu, O.O.; Ajayi, D.M.; Ogunrinde, T.J.
Statement of problem. Poly(methyl methacrylate) (PMMA) obturator bulbs are hard and nonresilient. The relief for these obturators limits the support available for the bulbs and may limit mastication on the side with the resection. Resilient liners may improve mastication by gaining greater support from closer contact with tissues within the defects. Purpose. The purpose of this crossover clinical trial was to compare masticatory function scores of individuals with maxillectomies rehabilitated by using all-PMMA and PMMA obturator bulbs lined with resilient silicone. Material and Methods. Twelve participants with maxillectomies were provided with 2 definitive obturator dentures after initial rehabilitation. One of the obturator dentures had a hollow obturator bulb in all-PMMA, while the other had a hollow-core PMMA with an outer layer of silicone-resilient liner. Participants wore each obturator for a 2-week period without washout. Masticatory function on the rehabilitated sides was assessed by using an adapted Sato questionnaire. Statistical analysis was performed by using paired t test results of mean masticatory function scores (a=.05). Results. Participants found 98.35% of the foodstuffs easy to masticate on the dentate sides. An average of 60.40% of the participants found the foodstuffs easy to masticate on the rehabilitated sides with the silicone-lined obturators. 18.35% of participants found the foodstuffs easy to masticate with the all-PMMA obturators (P<.05). Conclusions. Resilient lining of PMMA resin obturator bulbs significantly improved masticatory ability in rehabilitated areas of the mouth. (J Prosthet Dent 2016;-:---)
Endodontic Treatment Of Unusually Long Discolored Maxillarycentral Incisor: A Case Report
(2013) Abiodun-Solanke, I.M.F.; Ajayi, D.M.; Abu, A.O.
Background: Success in root canal treatment is achieved after thorough bio mechanical preparation followed by complete obturation of the canal system together with prompt and adequate restoration. Therefore, the endodontic therapy requires specific and complete knowledge of the internal and external anatomy, and its variation in presentation. Such treatment may be performed in root canal systems that do not comply with normal anatomic features described in standard textbooks. This article presents a case of endodontic treatment in an unusually long discolored maxillary central incisor. Case Presentation: A 31 year-old male patient was referred to conservation clinic for endodontic treatment of discolored left maxillary central incisor with associated history of recurrent swelling. Root canal therapy was performed and patient was found to have an unusually long working length of 29mm. This was then followed by enucleation of apical cyst without apical resection. Conclusion: Though the patient presents a maxillary central incisor with canal length in the upper limit of some reported cases, it is unusual in our environment.

(2016) Ogunrinde, T.J.; Abiodun-Solanke, I.M.F.; Ajayi, D.M.
Introduction. Tooth loss (edentulism) is an irreversible oral condition that has been described as a final marker of disease burden for oral health. It can impact the quality of life of an individual as it may affect speech and ability to chew properly. Aim of the study. To assess the effect of tooth loss on the quality of life of the Nigerian population using the Oral Health Impact (OHIP) questionnaire, and to determine factors that influence the severity of tooth loss impact. Material and method. A cross-sectional study was performed among partially edentulous patients at a Nigerian teaching Hospital. The Oral Health Impact (OHIP) questionnaire was used to obtain information from the participants. Data collected through the questionnaire were analysed using SPSS version 17 software. Chi square test was used to assess the correlation between the quantity and location of tooth loss and impact of tooth loss on the quality of life. The level of significance was set at P≤0.05. Result. One hundred and sixty five partially edentulous patients participated in the study. There were 80 (48.5%) males and 85 (51.5%) females. The highest mean impact score was 2.27 and was recorded for the question “Have you found it uncomfortable to eat any food because of your missing teeth”? Of the seven domains of OHIP, the highest mean score (4.2) was recorded for the physical pain domain. There was a statistically significant relationship between the location of missing teeth and the severity of impact on the quality of life of the participants. Conclusion. Missing anterior teeth had significant impact on the quality of life of the patients
Impact of Tooth Surface Loss on the Quality of Life of Patients Seen in a Nigerian Teaching Hospital
(2020) Ogunrinde, T.J.,; Ajayi, D.M.; Abiodun-Solanke, I..F.
Background: Tooth surface loss (TSL) is a progressive process arising from erosion, abrasion, attrition or abfraction. It can affect individuals of any age group: children, young adult, adults or the elderly and can compromise the health of individual tooth or the entire dentition leading to poor quality of life of the affected person. Objective: To evaluate the pattern of TSL among dental patients in a Nigerian Teaching Hospital and to assess the impact of TSL on their quality of life. Subjects and Methods: The study was a cross-sectional study among patients with TSL in a Nigerian Teaching Hospital. The Oral Health Impact Profile-14 (OHIP-14) questionnaire was used to obtain information on the impact of TSL on the quality of life of the participants. Data collected were analysed using IBM SPSS version 20. Chi-square test was used to assess association between types of TSL and quality of life of the patients. Level of significance was set at p ≤ 0.05. Results: One hundred and twenty-five patients (Males = 72; Females = 53) with tooth wear lesions participated in the study. The most common type of tooth surface loss was attrition (40%) followed by abrasion (23.2%). The highest impact of TSL on the quality of life was painful sensation strongly affecting 39 (31.2%) patients. This was followed by problem with chewing. There was no statistically significant relationship between patients’ quality of life and types of tooth surface loss. Conclusion: The most common negative impact of TSL on patient quality of life was painful sensation.
Microwave disinfection of maxillary and mandibular denture bases contaminated with Candida Albican
(2015) Bamigboye,S. A.; Dosumu, O.O.; Ajayi, D.M.
Background: Oral environment is not sterile, and dentures worn by the patients can be infected and therefore needs disinfection. Solution disinfectants such as sodium hypochlorite and glutaraldehyde can be used but they have side effects. Microwave disinfection method is more recent, however, there are conflicting reports at the moment on the appropriate power and time regimen for disinfection of denture. Objective: To determine the power and time regimen at which the disinfection of dentures can be achieved using microwave. Method: Forty-five acrylic denture bases were fabricated for each of the jaws and infected with solution of a stock Candida albicans and 30 infected bases were employed as control. These were placed in normal saline and then subjected to different microwave power and time regimen. Aliquots from these post-microwave solution were titrated against sabauraud agar which was subsequently incubated at 37oC for 48 hours. The agar were examined for candida growth. Result: The denture bases subjected to microwave disinfection at 350W showed Candida growth after microwave treatment irrespective of the time employed. Conversely, those microwaved at 650W and 690W for four and six minutes showed no microbial growth. Conclusion: The microwave regimen of 650W at 4 and 6 minutes completely disinfected the denture bases. Disinfection at higher microwave energy should be done with caution as distortion of the denture may occur.
Patients’ waiting experiences and satisfaction with oral care delivery at two levels of care in Ibadan, Nigeria
(2018) Abiodun-Solanke, I.M.F.; Lawal, F.B.; Ajayi, D.M.
Background: Patients waiting experiences at the dental centre and their satisfaction with services rendered by the health care team have not been fully explored and may be important factors that have influenced the pattern of utilization of dental services in this part of the world. The aim of this study was to determine what patients’ waiting experiences are, at two dental centres and find out how satisfied patients were with the services provided. Methods: A cross sectional study was conducted at two dental centres in Ibadan, Oyo State, Nigeria over a period of twelve months. Data was collected using a 29-item structured questionnaire. Information sought were patients’ biodata, reasons for presenting at the dental centre, time on entry into the centre, their experiences from point of entry into the dental centre to consultation with the dentist and how satisfied they were with the services rendered. Data were analyzed using SPSS version 22. Results: Two hundred and sixty-six respondents participated in the study with a mean age of 36.3 ± 17years. The mean waiting time at the Primary Oral Health Care Center (POHCC) and tertiary health centre (UCH) were 11.5 ± 17.0 and 102.3 ± 47.3 minutes respectively. Many (85.3%) were satisfied with the services offered by the dentist, 78.0% were comfortable while waiting to see the doctor. Patients attending the POHCC were more satisfied with the stage of dropping appointment cards but less satisfied with the stage of being called in to see the doctor (22.9%) and when with the doctor (20.6%) compared with patients attending UCH (13.3%)(p<0.005). Conclusion: Many patients were comfortable while waiting to be seen by the dentist and the majority were satisfied with the stages of service delivery. However, causes of dissatisfaction and discomforts experienced by some of the patients will have to be addressed.
Pattern Of Iatrogenic Damage To Approximal Tooth Surface During Class Ii Cavity Preparation In A Clinically Simulated Environment
(2014) Arigbede, A.O.; Ajayi, D.M.; Abiodun-Solanke, I.M.F.
Background/Aim: Iatrogenic tooth damage is a well recognized and longstanding problem that appears to have refused to disappear from restorative clinical practice. This study was designed to determine the pattern of distribution of iatrogenic tooth surface damage caused by a cross section o f dental students and residents during Class II cavity preparation in a clinical simulated environment. Methods: Residents rotating through the Department of Restorative Dentistry and randomly selected 1SI year and final year dental undergraduates were told to prepare either mesio-occlusal or disto-occlusal Class II cavity on pre-selected normal upper plastic posterior tooth mounted on phantom head after obtaining inform consent. The type of preparation that is selected is based on the adjacent tooth surface that is intact. At the end, the location of the damage and the type (Groove; indentation; Scratches; Extensive) as described by Medeiros and Seddon (2000) was evaluated under a magnifying lens. Summary statistics was generated. Results: The frequency of iatrogenic tooth damage was 100% and “indentation” was the commonest pattern, followed by grooves. More damages occurred in the cervical area. Extensive damage formed 19.0% of the total damages and this type of damage was found more adjacent to MO cavity (25.0%) compare to DO (15.4%) but there was no difference between the extensive damage that occurred on the right and left sides. Conclusion: The frequency of iatrogenic tooth damage was 100% and indentation was the commonest pattern. Extensive type of damage was found more adjacent to MO cavity.
Perceived Sources of Stress and Coping Strategies among Clinical Dental Students in Two Nigerian Universities
(2016) Abiodun-Solanke, I.M.F.; Ajayi, D.M.; Sigbeku O; Ashiwaju, M.O.
Background: Dentistry is perceived as a highly stressful profession and the dental school is often where the stress begins. Contemporary dental curricula require students to attain diverse proficiencies such as acquisition of theoretical knowledge, clinical competencies, skills acquisition and best practices which add up to stress. The objectives were to identify the sources of perceived stress, and the coping strategies adopted by clinical dental students in two Nigerian Universities. Materials & Methods: A cross-sectional study involving all clinical students in the two oldest dental schools in Nigeria. A validated self administered, structured questionnaire comprising of the modified version of dental environmental stress survey(DES), the perceived stress scale and brief coping scale was used in collecting data from the participants. Results: The potential sources of stress which were most frequently reported were the academic factors with volume of learning rated highest (84.2%) followed by demanding curriculum (72.6%) and frequent formative and summative assessment (51.7%). Inadequate infrastructures and erratic power supply were considered the most frequent(70.7%, 67.6%) sources of stress among the physical and environmental factors. Workload was also a major concern for stress with requirement to perform specified types and number of procedures rating the highest(76.9%) followed by time limits(69.8%). More (47.8%) females pray/ meditate while 29.6% cry as a means of relieving stress while the males play games which are all statistically significant (p= 0.003, 0.001 and 0.000 respectively). Conclusion: The most frequently reported source of stress are the academic factors with volume of learning rated the highest followed by demanding curriculum and frequent examinations. The strategies adopted to cope with stress across the gender were praying and crying among females and playing games in males

Prevalence and Distribution of Cracked Posterior Teeth among Adult Patients
(2020) Ogundare, T.O.; Ajayi, D.M.; Idon, P.I.,; Bamise, C.T.,; Oginni, A.O.; Esan, T.A.
Background: There are challenges in detection and prevalence of cracked teeth, especially in asymptomatic cases. This underestimates the actual prevalence and possibility of preventive restorative treatment. Objectives: To determine the prevalence and distribution of cracked posterior teeth among adult patients attending the dental clinic of OAUTHC, Ile-Ife, Osun State, Nigeria. Materials and Methods: A cross sectional study where consecutive patients aged 18 years and above were examined for the presence of cracked posterior teeth over a period of one year (May 2016-April 2017). The teeth were initially examined with the naked eye. Thereafter, transillumination, methylene blue dye and magnifying lens were used to aid detection of more cracks. Data was analyzed with the IBM Statistical Package for Social Sciences (SPSS) for Windows (version 21.0). Level of significance was set at p ≤ 0.05. Results: Out of the 64,370 posterior teeth examined for cracks in 3345 patients, 264 were diagnosed as cracked in 152 patients, giving a patient prevalence of 4.5% and tooth prevalence of 0.4%. Amongst the 152 patients, the prevalence was 9.1%. There was a slightly higher male preponderance while cracked tooth was observed to increase with age (p = 0.007). The skilled (56.6%) and those that attained tertiary education (77.6%, p = 0.023) had more cracked teeth. Mandibular first molar (19.7%) was the most frequently cracked tooth type. The cracks were usually centrally placed (91.7%) and run in a mesiodistal direction (61%). Transillumination (44.7%) detected more cracked teeth. Conclusion: Prevalence of cracked tooth was observed to be low with a slightly higher proportion in male and the figure increases with age. Mandibular first molar was the most frequently cracked tooth while transillumination was the most useful diagnostic tool. Most cracks ran in the mesiodistal direction and fracture lines were usually centrally placed.
Resident doctors’ perception and practice of resin-bonded bridges
(2019) Abiodun-Solanke, I.M.F.; Ajayi, D.M.; A Egbe, A
Background: Resin bonded bridges (RBB) was introduced as an alternative to conventional bridges for tooth replacement under certain clinical conditions. It was designed as a temporary restoration which is reversible and the clinicians’ major concern has been its longevity. The major cause of failure was attributed to de-bonding caused by complex multi- directional inter-abutment stresses associated with the 3-unit bridge that challenges the retainer and adhesive bond. The study aimed to assess the attitude, knowledge and practice of resident doctors on the performance factors of RBB. Methods: A cross-sectional study conducted amongst residents at an update course using self –administered questionnaires. The first part of the questionnaire consisted of questions related to participants’ sociodemographics, intended area of expertise, years of experience and percentage of RBBs performed in their clinical prosthodontic / restorative practice. The second part of the questionnaire comprised closeended multiple-choice questions which were designed to extract the opinion and understanding of the respondents regarding performance factor for RBBs. The questions were related to clinical indications, prosthesis design etc Results: Eighty percent of the participants indicated that had <10% tooth replacement service was done with RBB, 44.7% of the respondents considered RBB as a provisional restoration while 28 (36.8%) regarded RBB as both provisional and permanent restoration. About 76% of the respondents believe that perforated retainers were associated with clinical success of RBBs. 70% considered anterior maxilla as the most favorable location while class 1 jaw relation was preferred by 60% of participants Conclusion: With less than 10% of teeth replacement done using RBBs, there is a need for continuing education opportunities for practicing dentists and better exposure of undergraduate and postgraduate students to clinical application of RBBs
Self Reported Musculoskeletal Pain Among Dentists
(2011) Abiodun-Solanke I.M.F; Ajayi, D.M.; Agbaje J.O.; Arotiba J.T.
Background: Musculoskeletal complaint is an important health issue among dentists. Given the significance of this topic, we considered it necessary to investigate the prevalence and impact of musculoskeletal disease among Nigerian dentists Aim/Objectives: To assess the work- related complaints among dentists with the specific objective of finding out the prevalence of neck and back pain among dentists Materials and Methods: A structured questionnaire was sent to tivo hundred and fifty practising dentists in 3states capitals which were randomly selected from South - Western Nigeria. Participants were drawn from general hospitals, private clinics and teaching hospitals. Participants included general practitioners, specialists in restorative dentistry, oral and maxillofacial surgery, child oral health (pediatric and orthodontists), period ontology and oral pathology. Results: The response to participate in the study was 66.7% out of which 60% correctly filled questionnaire was analyzed. The mean age of participants was 32.8 ± 6.8years (SD) with a male to female ratio of 1.4:1. Prevalence of back pain was 89.6% while that of neck pain was 81.3%. Back pain was found to be higher in females (91.7%) compared to males (88.1%) while neck pain was higher in males (82.1%) compared with to females (80.0%). Back and neck pain were highest in those who worked 8-12 hours per day. Back pain was highest(94A%) in those who had practiced for 6-10 years while those who had practiced for more than 20 years reported *the highest percentage of neck pain. Respondents in restorative dentistry all had back pain at one time or the other over a period of twelve months, while neck pain was highest among respondents in child oral health(91.7%) . 43% of respondents perform their procedures standing, while 38% use the sitting position and 19% alternate between standing and sitting position. Other work related complaints reported by the dentists include headache, shoulder pain, pain around the wrists and paresthesia of the fingers of the dominant hand More respondents missed work due to back pain irrespective of the gender. 17 respondents sought medical help due to neck pain out of which 8(47.1%)) received only analgesics while among those who sought medical attention due to back pain, 7(63.7%) received analgesics only. Conclusions: Occupational related health problems among Nigerian dentists were common. There is a substantial need and demand for further training in occupational health and safety among dentists.
The influence of the design of mandibular major connectors on gingival health
(2014) Ogunrinde,T.J.; Dosumu, O.O.; Shaba,O.P.; Akeredolu, P.A.; Ajayi, D.M.
Background: The objective of this study was to assess the influence of lingual bar and lingual plate major connectors on plaque retention and gingival health among patients who presented in University College Hospital (UCH), Ibadan, Nigeria. Methods: This comparative intervention study was carried out among fifteen patients aged 28 to 60 years with Kennedy class III lower edentulous arch. Two metal dentures with different major connector designs (lingual plate and lingual bar) were fabricated for each patient. After professional scaling and polishing, a baseline score of the oral hygiene was done using the plaque index of Sillness and Loe and the gingival health using the gingival index of Loe and Sillness. Each patient was randomly assigned either a denture with the plate or bar design to use for three months and then recalled for reassessment of oral hygiene and gingival health. Professional scaling and polishing was done post removal and a new baseline assessment of oral hygiene and gingival health recorded. The dentures were now exchanged and the second major connector design inserted. Each patient was recalled for reassessment of the oral hygiene and gingival health after three months. The level of plaque accumulation and gingival inflammation with the use of lingual plate and bar dentures were determined and compared. Results: There was no statistically significant difference in the mean plaque index score for the lingual bar design at three months and the mean plaque index score at three months for the lingual plate (p>0.05). However, a statistically significant lower mean gingival index score was noted three months post insertion for lingual bar designs when compared to plate designs. Conclusion: Within the limitation of this study, better gingival health was noted with the bar designs when compared with the plate designs.
