Item Resident doctors’ perception and practice of resin-bonded bridges(2019) Abiodun-Solanke, I.M.F.; Ajayi, D.M.; A Egbe, ABackground: 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 RBBsItem 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.Item 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 malesItem Tooth reattachment: knowledge and practice of Nigerian dentists in postgraduate training(2017) Ajayi, D.M.; Gbadebo, S.O.; Abiodun-Solanke, I.M.F.Introduction. Trauma to teeth is relatively common and reattachment of fractured fragment is one of the available treatment modalities. It is conservative, provides immediate treatment with natural esthetics and faster restoration of function. Aim of the study. To assess the knowledge of resident doctors on tooth reattachment and investigate how much of this has been translated into current good clinical practice. Methodology. A cross-sectional study that made use of structured self-administered questionnaires completed by resident doctors from different dental specialties in Nigeria. The questionnaire included the demographics of respondents, knowledge about tooth reattachment, sources of information, practice of the procedure amongst others. Data was analysed with SPSS version 20, and p-value was set at ≤0.05. Result. Participants were aged between 28 and 57 years with mean of 35.1±5.7 years. The majority (95.7%) claimed they had heard about reattachment and 46.7% of these had more than one source of information. About 53% claimed it is indicated in tooth fracture while 4.3% of them stated that tooth avulsion is an indication. Also 53.2% believed that only anterior teeth could benefit from this procedure. Forty-two respondents had observed reattachment procedure before, out of which 18 (42.9%) had actually done it (p=0.04). A majority (89%), however, indicated a willingness to have a hands-on training workshop on the procedure. Conclusion. Though there is good awareness of reattachment, the practice is very low in this environment. There is, therefore, a need to create even more awareness on the current standard of practice of tooth reattachment among Nigerian dentists.Item Impact of tooth loss on the quality of life of patients seen in a Nigerian teaching hospital(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 patientsItem Dental Implant Treatment At A Nigerian Teaching Hospital(2014) Ajayi D.M.; Abiodun-Solanke, I.M.F.; Gbadebo, S.O.; Fasola A.O.; Dosumu, O.O.; Arotiba, J.T.Background: There has been an increase in the awareness of dental implant as a replacement option for missing teeth and this has consequently led to an increased demand for dental implant. Aim & Objective: To determine the distribution and pattern of implant placement in a tertiary hospital in a developing country. Materials and Methods: This retrospective study was conducted at the University College Hospital to assess the treatment outcome of all the patients who had had osseointegrated root form endosseous dental implants over a period of five years. The data obtained included age, gender, socioeconomic status (SES), medical history, reason for implant placement, number of implants per patient, distribution of missing teeth, complications and treatment outcome. The data were analyzed for percentages, means, SD and presented in tables and figures. Results: Forty two implants (40 conventional & 2 immediate) were placed in the 23 patients (M-15, F=8).There were 15(65.2%) males and 8(34.8%) females. Pre-implant placement ridge augmentation was done in 3(7.1%) patients while 9 (39.1%) patients had augmentation during implant placement surgery. Left maxillary central incisor was the most commonly replaced tooth in 31% followed by the right maxillary central incisor in 19%. The success rates in the study at 1 year and 5 years were 97.4% and 95.2% respectively. Conclusion: A high success rate (95.2%) of implant therapy at 5 years recorded in this study compared favorably with what is obtainable in many other countries of the worldItem 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 .Item 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.Item 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.
