Objectives: The primary aim of this study was to investigate the potential correlation between dental caries and incisor irregularity. The secondary aim is to explore for other risk factors that could be associated with dental caries. Methods: Participants were screened and recruited based on the study’s inclusion criteria from Taibah University Dental Hospital, Madinah, Saudi Arabia. Clinical Intra-oral examination for incisors irregularity using Little’s Irregularity Index for each arch separately. The frequency of surface caries was calculated by the sum of the decayed, filled lesions per tooth surface (DFS) scores per arch. Followed by a questionnaire to record the participant’s demographic data, oral hygiene and dietary habits to control for confounding variables.

Results: 153 adult patients participated in the study with mean age of 29 years old (SD ± 10). The mean Little’s Irregularity Index for the upper and lower anterior teeth was 3.61 and 5.44 millimetres, respectively. While the mean DFS scores were 2.24 and 0.58 for the upper and lower anterior teeth, respectively. The mean frequency of daily sugar intake per person was 3.38 times. Multiple linear regression analysis reported that no significant correlation exists between incisor irregularity and DFS scores in either the maxillary or the mandibular arch.

Conclusion: The increase in incisor irregularity was not associated with the increased frequency of carious surfaces in the study sample. However, other factors demonstrated significant positive correlation such as the increased frequency of daily sugar consumption and decreased frequency of tooth brushing. Oral health education and promotion of healthy habits are recommended to minimize the risk of caries development.
