(2017) Abiodun-Solanke I.M.F.; Ajayi D.M.; Sulaiman A. O.
Aim: The purpose of this investigation was to document the reasons for placement, and replacement of crowns and fixed partial denture in a Nigerian Teaching Hospital. Methods: a retrospective review of patients that had advanced conservative procedures. A data collection form was used to gather the relevant information from the patients’ case notes. Section A sought information on age , gender, educational level, patients’ occupation etc. Section B recorded information on tooth/teeth involved, reason for fabrication of prosthesis and material used. Results: Three hundred and twenty six had 398 crowns while 23 patients received bridges. Patients’ ages ranged from 16-85 years with a mean of 47.7 ± 17.2 years and a male to female ratio of 1:1.3. Thirty five percent of the crowned teeth were in the upper right quadrant, followed by the upper left quadrant with 29.4%. Upper right central incisors were the most frequently (15.6%) crowned teeth. Endodontics and esthetics were the most common reasons for initial crown placement and replacement respectively. About 60% of bridges fabricated were new, while 22.2% of replaced bridges were due to fracture of porcelain and unacceptable marginal adaptation. Conclusion: Endodontics and esthetics were the most common reasons for initial crown placement and replacement
The practice of mercury hygiene among Nigerian dentists in three southwestern states
(2015) Iwaola,M.O.; Ajayi, D.M.; Abiodun-Solanke I.M.F.; Oke, G.
Background: Dental amalgam has been in use for a very long time in the field of restorative dentistry as an intracoronal restorative material. Despite its long usage, there have been reports about adverse health effects arising from the exposure to minute mercury released from amalgam to the dentists if not properly handled. Aim: The aim was to find out the compliance of Nigerian dentists with recommendations on mercury hygiene practices. Materials and Methods: A cross-sectional study using self-administered questionnaire consisting of three parts was conducted among registered dentists. The first part of the questionnaire sought demographic characteristics of. respondents while second part assessed measures taken by the caregiver himself while working with amalgam and the last part assessed measures taken to control and prevent mercury contamination within the clinical setup. Result: There was total compliance with the use of gloves when working with amalgam among the participants. However, the house officers had the highest tendency of always wearing face mask and protective clothing followed by specialist in training. There, was a statistically significant difference in the tendency to always wear face mask (x2 = 2.1.37, P= 0.00) and protective clothing (y2 = 24.77, P= 0.00) as against occasional and never wearing them,' among the different categories of dentists. Compliance with the use of .rubber dam and alternative source of air was found to be generally poor among the professionals studied. More than two-third of all dentists studied never used the two preventive measures. About 78% never used rubber dam when working with amalgam. The method of handling excess mercury was found to be more appropriate among the respondents in the teaching hospitals and poorest among those in private set-up. Furthermore, a great majority (87.5%) of those working in private clinics had never heard of mercury vapor monitoring. Conclusion: It was noted that some of the standard mercury hygiene practices such as the use of rubber dam, high volume suction, and water cooling when removing or polishing amalgam restorations were not followed properly.
A Survey of Knowledge and Practice of Regenerative Endodontics Among Nigerian Dental Residents
(2014) Ajayi D. M.; Abiodun-Solanke I.M.F.; Gbadebo S.O.; Abu A.
The aim of this survey was to assess the knowledge, attitude and practice of regenerative endodontics among dental residents in selected Nigerian hospitals. A self-administered questionnaire was used for the survey. It consisted of three parts; part A asked questions about dentists profile and knowledge, part B sought the dentist’s opinion, beliefs and judgement regarding the use of RE procedures while part C consisted of questions based on clinical practice. The results shows that the majority (91.2%) have heard about REPs which was mainly through postgraduate training but 91.9% were willing to attend courses on REPs. Most (89.1%) of participants believed that stem cell banking will be useful to regenerate dental tissues, however only 42.4% claimed to have been using some type of regenerative therapy in their practice and 28.9% considered tribiotic paste and pulpal regeneration as optimal treatment for necrotic immature teeth while 36% considered CaOH +MTA+ obturation material as the best option. As a final conclusion we can say that these results reflect that dental residents are optimistic about the use of regenerative endodontic procedures; however, a need for more research and regular training was felt
