Objective: The aim: To compare the patients' self-evaluations of oral hygiene and oral health with the results of the clinical examination expressed using both the DMFT index (DT, MT, FT) and the API index; and to evaluate the relationship between the patients' general health behaviors and their oral health status.
Patients and methods: Material and Methods: 78 first-time dental patients (40 females, 38 males; Mage=40,7, SD=14.4) participated in the study. Prior to the initial dental visit, a questionnaire consisting of statements measuring self-rated oral health, hygiene and the patient's knowledge about the oral cavity and the Health Behaviour Questionnaire (HBI) was administered. DMFT index, dental treatment index (DTI), and Approximal Plaque Index (API) were assessed upon intraoral examination.
Results: Results: The analyses revealed that the self-declared level of knowledge about the oral cavity was significantly related to the API (p=0.004), to the number of DT (p<0.001) and to the number of FT (p<0.001). There was a correlation between the patients' declared state of the oral cavity and number of DT (p<0.001) and FT (p<0.001). The total HBI score correlated positively with FT (p=0.049). Health behaviours were related to the self-evaluation of oral care (p≤0.19), oral condition (p≤0.001), and knowledge of the oral cavity (p≤0.008).
Conclusion: Conclusions: There is a significant relationship between the self-declared condition of the patients' oral cavity and their oral care and DMFT index. The higher the level of a patient's declared health behaviours, the better both the self-evaluated, and objectively assessed, state of the oral cavity.
