Objective: In the healthcare setting, periodontal disease is among common dental disease resulting in tooth loss. Given its increased prevalence, the study determines the correlation between oral hygiene and periodontal conditions using radiographic data. Methods: A cross-sectional study design was used and radio-graphic data of 1000 patients (aged 16 years or above) from King Abdul Aziz University Faculty of Dentistry (KAUFD) was assessed. The patients were divided into four groups based on their type of restoration; such as amalgam (77), composite (65), a crown (44), and temporary (11). Data was collected through questionnaire-based approach, which was analyzed statistically using SPSS. Results: Majority of the patients had fair oral hygiene (53.8%). The correlation analysis of oral hygiene with the restoration surface (p-value 0.571) and control tooth surface (p-value 0.476) was insignificant. Similar results were obtained for case tooth (crown restoration) (p-value, .356) and control tooth (p-value, .925). However, there was significant effect of oral hygiene on restored tooth bone loss (p-value, 0.004) and control tooth bone loss (p-value, 0.003). Conclusion: The study presents instigating initiatives to reinforce oral hygiene and educate general masses about periodontal conditions and its prevention.
