Background: Dental caries is the most prevalent oral disease. It affects both sexes, all races, all socioeconomic ranks and all age groups.
Objective: To determine the prevalence of dental caries among dental patients presenting at a secondary healthcare facility in Southern-Nigeria.
Materials and Methods: A 5-year retrospective descriptive study was conducted at the dental department, Central Hospital Oleh, Delta State. Variables of interest extracted from the records included age, sex, decayed teeth, missing/extracted teeth, filled teeth, tooth type, jaw type and oral hygiene status. Cases with incomplete data were excluded. Analysis of data was done using the IBM® SPSS® Statistics version 25 software. Association between variables was tested using Fisher’s exact, independent t-test and one-way analysis of variance.
Results: A total of 847 cases containing the variables of interest were retrieved from the hospital records. The mean age of patients was 38.94 years. The prevalence of dental caries was 43.2% (n = 366). The mean deft was 0.62  and the DMFT, 1.04 . Dental caries occurred more significantly on the mandible (57.8%) than the maxilla (42.2%) and was significantly more prevalent on the first molars (32.9%).
Conclusion: The number of untreated dental caries was high, and the restorative index was low among the patients. The overall caries prevalence was high; however, the mean DMFT/deft was low compared to other Nigerian studies.
