Background:The development of success-oriented hepatitis-B vaccine uptake approach among dental surgeons is dependent on the availability of comprehensive baseline data.Objective:To determine the hepatitis-B vaccination status among dental surgeons in Benin City.Materials and Methods:This questionnaire-based cross-sectional study of dental surgeons in Benin City was conducted in May 2011. The questionnaire elicited information on demography, occupational risk rating of contracting hepatitis-B infection, hepatitis-B vaccination status, barriers to uptake of hepatitis vaccine, and suggestions on how to improve hepatitis-B vaccination rates among dental surgeons.Results:Participation rate in the study was 93.3%. More than half (51.4%) of the respondents were 20–30 years old and 52 (74.3%) were males. The occupational risk of contracting hepatitis-B infection among dental surgeons was rated as either high or very high by 51 (72.9%) of the respondents. Amongst the respondents, 14 (20.0%) had received three doses of the hepatitis-B vaccine, 34 (48.6%) either two doses or a single dose, and 22 (31.4%) were not vaccinated. The major barriers reported among the respondents who were not vaccinated were lack of opportunity and the fear of side effects of the vaccines. The suggested ways to increase the vaccination rate among the respondents in descending order include: Making the vaccine available at no cost (51.4%), educating dentists on the merits of vaccination (17.1%), and using the evidence of vaccination as a requirement for annual practicing license renewal (14.3%) and for the employment of dental surgeons (11.4%) and others (2.9%).Conclusion:This study revealed low prevalence of complete hepatitis-B vaccination among the respondents. Improvement in uptake following the respondents’ recommendations will serve as a template in developing success-oriented strategies among stakeholders.
The roles of bacteria in the etiopathogenesis of periodontal disease are well-understand, but that of the virus found in the periodontal environment are poorly understood. The aim of this literature review was to report the roles of viruses in periodontal diseases. The roles of viruses in periodontal diseases were categorized into the role in disease etiology, role in the pathogenesis of periodontal diseases, role in diseases progression and role in response to treatment. Clearer understanding of roles of viruses in periodontal diseases will facilitate the provision of effective periodontal disease prevention and treatment.
Objective: To determine the periodontal characteristics of diabetic patients with tooth mobility attending the Periodontology Clinic of University of Benin Teaching Hospital (UBTH), Benin City, Nigeria. Materials and Methods: This cross-sectional observational study was conducted among diabetic patients with tooth mobility in the Periodontology Clinic in UBTH, Benin City, Nigeria. The indices recorded for the participants were gingival index, community periodontal index of treatment need, and Miller'sindex for tooth mobility. Results: A total of 54 participants who met the inclusion criteria were approached, but only 49 of them consented and participated in this study giving a 90.7% recruitment rate. The age range and mean age of the participants were 42–84 years and 63.84 ± 1.31 years, respectively. The self-reported age of diagnosis was between 41 and 70 years with a mean age of 56.22 ± 6.88 years. About two-thirds (67.3%) of the participants were males. Less than half (38.8%) of patients were visiting the dentist for the first time. Mandibular arch housed about two-thirds (64.9%) of the mobile teeth and mandibular left quadrant housed about one-third of (34.5%) the mobile teeth. Central incisor (42.3%) constituted the most mobile teeth followed by the first molar (28.9%). A total of 17.0% of the mobile teeth were Miller's Grade 3 mobility. More than one-third (28.5%) (code 3 = 26.5%, code 4 = 2.0%) of the participants had periodontal pockets. More than half (52.7%) of participants had probing pocket depth of 5 mm and above. The gingival score which had mean as 1.60 ± 0.08 was significantly associated with age of the participants. The mean probing depth was 4.86 ± 0.21 mm. The probing depth was significant with age and duration of diabetes mellitus (DM) of the participants. Conclusion: Data from this study revealed that age of diagnosis of diabetes with tooth mobility was higher than previously reported. The most mobile teeth and earliest teeth to become mobile were the mandibular incisors, and Grade 1 severity constituted the majority. DM with tooth mobility exhibited gingival score and probing depth that had a variable significant association with demographic characteristics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
