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