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 world
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;-:---)
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.
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.
