Objective: To evaluate the prevalence and severity of plaque-induced Gingival inflammation (GI) among Saudi adult population in Jeddah region.
Method: One hundred and ninety-seven eligible participants in this cross-sectional study were recruited from routine dental patients attending the Oral Diagnosis Clinic at AlFarabi College in Jeddah, Saudi Arabia from Nov 2019 to May 2020. A clinical examination was performed by 2 dentists to measure the gingival and plaque indices of Loe and Silness for each participant.
Results: The prevalence of gingivitis was 100% among adult subjects aged between 20-50 years old. Moreover, both the male and female groups with generalized Gingival inflammation (GI) had significantly higher mean scores of plaque index. In addition, females with generalized GI showed a significantly higher plaque index % compared to males (p<0.05). Bleeding on probing (BOP) of generalized GI was higher in females than males. In fact a significant and positive correlation was observed between plaque index % and BOP % in both male and female localized GI groups. This shows that the plaque index and BOP are dependent on each other. However, females were more affected with localized gingivitis than males (p=0.0001).
Conclusion: The results of this study show that plaque accumulation is strongly associated with high prevalence of generalized and localized gingivitis among Saudi subjects.
