Gingival health was influenced by gender, socioeconomic status, oral hygiene frequency and toothbrush texture. Motivation to apply instructions given on oral health care and regular reinforcement are essential.

This study assessed the practice of disposing of waste from the eight dental clinics of Obafemi Awolowo University Teaching Complex, Ile-Ife, Nigeria. All the cleaners (14) in the hospitals were surveyed through questionnaire. Information obtained from the cleaners included socio-economic characteristics (biodata), personal protection, facilities available for them to work with and job satisfaction. Two soil samples were obtained from the open dump site (0.15 and 0.30 m depth) and two water samples were also collected (at 0.00 and 50.00 m) within the vicinity of the dump site. Both the soil and water samples were taken to the central science laboratory for chemical analyses. Ten (71.4%) of the 14 cleaners were not satisfied with their job. The laboratory findings suggested a very high content of lead, chromium, mercury, cadmium and manganese in both soil and water samples in comparison with the Nigerian Federal Environmental Protection Agency standards. The study concludes that the use of tooth-coloured restorative materials and digital X-ray facility to serve as alternatives to the generation of these wastes is recommended and that farming activities should not be allowed in the area until an audit of the soil and water have been performed.

Prevalence of tooth sensitivity was 68.4%. Presence of tooth sensitivity among these students was associated more with history of hard toothbrush use contrary to widely held belief that erosive agents were mostly responsible. Future studies are needed to provide more epidemiological data on tooth brushing and tooth sensitivity.

This study revealed a high-level misconception among secondary school pupils in Osun state, Nigeria. Mass media was the major source of information with doubtful effectiveness evidenced by obvious erroneous beliefs. An improved multisectorial approach in HIV/AIDS education with greater participation of school and public libraries is advised.

Objective The objective of this study is to evaluate the awareness of patients with dental fillings about the toxicity of mercury in dental amalgam. Materials and methods Adult patients having at least one amalgam filling in their mouth were recruited in the Oral Diagnosis Department of OAUTHC, Ile-Ife Dental Hospital. Participants were recruited consecutively as they report in the clinic. Data were collected using a structured questionnaire developed based on standard questions from relevant publications. They were asked to indicate the type of filling material in their mouth, ingredients of the material, previous knowledge of mercury in dental amalgam and ailments due to mercury. They were to indicate their level of agreement with filling their cavities with dental amalgam despite prior information about its mercury content. Results There were about 446 respondents analyzed; male, 194 (43.5%); female 252 (56.5%). Six (1.4%) and 21 (4.7%) respondents were primary and secondary schools students respectively; 15(3.4%) had no formal education while about 410 (91.9%) were either undergraduate or graduate. All of them had at least one amalgam filling. 249 (55%) participants know the type of filling on their teeth; 156 (34.5%) had the knowledge of the presence of mercury in dental amalgam while 26.1% believed mercury can cause problems in human beings. About 90 (19.9%) participants claimed to have heard about adverse reactions to dental amalgams and 34 (7.5%) of them have heard about people recovering from an illness after removal of their filling. The level of agreement with filling their cavities with amalgam despite prior knowledge of its mercury content was 74% while 60% was observed for allowing just any material to be placed on their teeth. Conclusion Awareness of toxicity of mercury in dental amalgam was slightly low among the respondents studied. This may be suggested to be a reflection of nonexistent of global amalgam controversy in Nigeria. How to cite this article Bamise CT, Oginni AO, Adedigba MA, Olagundoye OO.

AimThe objective of this study was to provide information on the level of utilization and satisfaction of residential university students with the dental services provided by the dental clinic of a teaching hospital.Volunteers and MaterialA stratified sampling technique was used to recruit volunteers from the outpatient clinic of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Information was collected by a self-administered questionnaire composed of questions that measure the level of utilization and satisfaction with the dental services provided. Questionnaires were provided to 650 randomly chosen students residing in the University hostels. There were 39 refusals, and 6 incomplete questionnaires were discarded. This left a sample size of 605 volunteers.ResultsForty seven students (7.8%) indicated that they visited the dental hospital within the last 12 months. Males and females utilized the dental services equally, and utilization increased with age and the number of years spent on campus. Anticipation of painful dental treatment, high dental charges, long waiting times and being too busy for a dental visit were cited as the most important impediments to seeking dental treatment. Females expressed greater satisfaction with the services.ConclusionDental service utilization among the students was found to be low. Oral health awareness campaigns, improving the quality of the services, and shortening the waiting time are expected to increase service utilization and satisfaction.
