Prevalence of Dental Caries and Predisposing Factors
Abstract
Prevalence of Dental Caries and Predisposing Factors in Obio-Akpor Local Government Area of
Port Harcourt
Background: Dental caries is a common oral health disease of global interest. The burden of the
disease and predisposing factors must be determined before a preventive programme could be
designed, but relevant data from community-based studies are not common in Rivers State.
Aims and Objectives: This study was designed to determine the prevalence and predisposing factors
to caries development in the Local Government Area (LGA).
Materials and Methods: This was a descriptive cross-sectional study carried out among adult
residents in Obio-Akpor LGA of Rivers State. An interviewer-administered questionnaire was used
to collect personal data and caries predisposing factors while oral examination was carried out to
determine caries severity and oral hygiene status using DMFT and OHI-S indexes respectively. The
sample size (240) was determined using the formula for descriptive studies.
Results: The mean (SD) age was 32(±1.113) years. Most of the participants were married, Ikwerres,
skilled workers, earn <100dollar and most had secondary education. Most seldom/never use tobacco
products. Most ate fresh fruits every day or several times a week and most also ate cariogenic diet
every day or several times a day. Most use fluoride toothpaste once a day and most do not use floss.
Most have never seen a dentist. The prevalence of untreated caries was 64.2%. DMFT score=0.91
(very low). The OHI-S = 3.3. (>3 indicates poor OHI).
Conclusions: The DMFT index was low while OHI-S was high. Poor oral hygiene status, oral
healthcare utilization and cariogenic diets predisposed the participants to caries.
Key words: Caries, prevalence, predisposing factors, prevention
