Prevalence of Dental Caries among Adult Patients Attending a Tertiary Dental Institution in South-South Region of Nigeria

ABSTRACT

Background: Oral health is an important component of the general health and dental caries status of a community is a good indicator of oral health status of that community. Epidemiological studies on dental caries are rare in the Niger Delta region of Nigeria. Aim: To determine the prevalence of dental caries among adult patients attending University of Port Harcourt Teaching Hospital Dental centre and to compare it with previously reported results. Methods: A cross-sectional study of all patients aged 18years and above presenting with dental caries at the centre over a one-year period was conducted. A self-administered anonymous questionnaire was used to get the socio-demographic data of the patients. The patients were all examined and caries was diagnosed using the WHO criteria (1997). Decay; missing and filled teeth (DMFT) were recorded and restorative index was calculated (F/F+D percent). SPSS version 15 was used to generate summary statistics and student t-test was used to compare means between two groups. Results: Out of 1;927 patients that presented during the study period; only 435 had dental caries or one of its sequelae giving a prevalence of 22.6. The mean DMFT score for the group was 3.57; that of females was 3.88 while that for males was 3.08. The difference in the mean DMFT scores between the two sexes was statistically significant (p=0.026). The restorative index was 25.3. Conclusion: The prevalence of dental caries in our centre (22.6) falls within the previously reported 4-30rates for Nigeria. The mean DMFT score was 3.51 and the restorative index is 25.3
