Objective. There is a change in the trends and distribution of dental caries in established and nonestablished market economies. The aim of this study was to describe caries distribution, prevalence, and treatment needs among school children in Port Harcourt, Nigeria.Materials and Methods. The study was a cross-sectional survey of students between the ages of 12 and 15 years. Data was collected using a structured questionnaire and clinical oral examination. Analysis of data was done using statistical package for social science version 20.0. Association between variables was tested using chi-square, independentt-test, and one-way analysis of variance.Results. The study population consisted of 195 school children of mean age13.21±1.09years. The prevalence of dental caries was 15.4% (n=30). The mean DMFT score for the entire group was0.25±0.66. Dental caries occurred more significantly (P<0.005) on the mandible (66.7%) than on the maxilla (33.3%) and was significantly (P<0.005) more prevalent on the first molars (66.7%) than on the second molars (26.6%).Conclusion. The number of untreated dental caries was high and the restorative index was low among the students. The overall caries prevalence and mean DMFT were low even when compared to other studies in similar populations in Nigeria.

Background: Health care associated infections are most commonly transmitted by the hands of Health care workers and other hospital personnel. Objective: To investigate compliance with hand hygiene guidelines and methods of hand hygiene practice among community health officers in Rivers State Nigeria. Methods: Self administered questionnaires were distributed to 68 community health officers. The questionnaires consisted of 19 items which contained information on bio-demographic characteristics and hand hygiene practices. Data were analysed using SPSS-16 statistical software. Proportions were compared using Chi-square test and 'p' value less than 0.05 was considered statistically significant. Results: The response rate was 97.1%. There were 11 (16.7%) males and 55 (83.3%) females with a male to female ratio of 1: 5. The age of the participants ranged from 28-56 years with a mean age of 39.7±6.7. Washing of hands before and after contact with patient was 60.1% and 97% respectively. The difference was significant (p<0.01). Allergy to gloves was 15.2%. About three-quarter (77.3%) of the workers used soap and water to wash the hands when soiled or visibly contaminated. None of the workers used alcohol hand rub. Conclusion: Though there was improved compliance to hand hygiene guidelines, this still fall short of acceptable standards. The provision and promotion of the proper use of alcohol-based hand rub may further improve compliance with hand hygiene by reducing the time required to perform it and the convenience of the method.

Objectives:This study seeks to investigate to what extent are students conversant with global oral health initiatives and policies, students’ willingness to volunteer service at international setting or developing countries and the need for global oral health course in Nigeria.Methods:Final year dental students in two Nigerian Universities were surveyed for this study. The students voluntarily completed the global oral health information questionnaire in a classroom before a scheduled lecture. The collected data were analyzed using IBM SPSS Statistic 20.Results:All the final year students participated in the survey. All the students agreed that they need to be taught course on global oral health and would consider volunteering their dental skills and expertise in an international setting or developing country. Only 4.5% of the students knew the meaning of the basic package of oral care (BPOC) and none of the surveyed students could correctly name the three components of BPOC. Whereas only 18.2% could identify World Dental Federation and World Health Organization as the bodies that developed global oral health goals for the year 2000, none of the students could correctly list the three components of global oral health goals for the year 2000.Conclusion:This study concludes that a gap exists in the knowledge of students on global oral health matters and recommends that the curricula of schools be constantly reviewed in line with current trends in policies and practices.
