Randomized controlled trial on the effectiveness of silver diamine fluoride in arresting caries in Lagos, Nigeria

Treatment of dental caries in children still remains challenging due to lack of cooperation with conventional treatment modalities. Recently, the use of Silver Diamine Fluoride (SDF) has proved useful in addressing this challenge. Aim: This clinical trial aimed to evaluate the effectiveness of Silver Diamine Fluoride (SDF) in arresting caries in children in Lagos, Nigeria. Methods: This was a phase III balanced randomized controlled school based interventional study on 240 children. The study group was treated with SDF while GIC was used in the control group. Follow up visits in 2 weeks, 1 month, and 3 months were carried out to assess the treatment outcome. Inferential statistics with the use of Pearson Chi-square test and Independent Student t-test were used at 5% level of significance. Results: There was significant relationship between SDF and caries arrest in 2 weeks, 1 month and 3 months' assessment period (p = 0.001). The control group showed continuous decline (71.7%, 54.3% and 50.9%) in restorative success from 2 weeks to 3 months respectively. The mean ± SD and Confidence Interval (CI) of arrested caries in the SDF group were 113± 1.24 and 113.1 ­ 113.5 respectively. In the control group the mean ± SD and CI of restorative success were 69.3±11.8 and 67.2 ­ 71.4. The effect size was 5.24. Conclusion: The result of the study showed that SDF was effective in arresting caries in children without any harm and there was statistically significant difference in the use of 38% SDF in arresting caries in children

Emerging trends in dental specialty choice in Nigeria.

Asymmetry in the distribution of dental specialists in Nigeria has the potential to negatively affect dental education at all levels. There is a dearth in Nigerian studies on the trends of influencing factors on the choice of dental specialty in Nigeria. Past efforts have not resulted in policy change thus necessitating the current study. One hundred and twelve (51 male, 61 female) Nigerian dental graduates aged 23-55 years with a mean age of 35.21 ± 8.21 years completed self-administered questionnaires to assess the impact of 16 influencing factors on their choice of dental specialty. The graduation period of respondents, which ranged between 0 and 30 years was recorded into three decades and cross-tabulated against 16 influencing factors to assess their relative impact on specialty choice. Diagnostic challenge, predictable work hours and patient type appeared to have maintained a consistent popularity while affluence and income, although less popular influences three decades ago are becoming increasingly relevant while length of programme, prestige and level of crowding exerted less influence on choice of specialty than other factors. The potential influence of incentives such as career counselling and grants for overseas training to encourage enrollment in less popular programmes was assessed based on recommendations from previous studies. However, these measures appeared to be unpopular among Nigerian dental graduates. Diagnostic challenges and predictable work hours remain popular as influencing factors on choice of dental specialty among Nigerian dental graduates. Affluence and income, although previously unpopular are now gaining popularity among Nigerian dental graduates.
