The Effect of Deep Traumatic Overbite on the Periodontium of the Upper Anterior Teeth in a Cohort of Adult Saudi Dental Patients
Main Article Content
Abstract
Aim: to assess the relationship between deep overbite with palatal impingement and periodontal health status in a cohort of adult Saudi dental patients.
Materials and Methods:Ten patients (4 males and 6 females, aged 16 to 31 years old) with deep traumatic overbite and palatal impingement were examined. A Hawley retainer appliance with an anterior bite plate was provided for all patients.Pocket depth, bleeding index, gingival index, plaque index and mobility were recorded for four visits after using the appliance with fixed intervals in-between. Repeated measures analysis of variance (ANOVA) was used to assess the differences between visits, control /experimental teeth and surfaces (palatal /labial) for pocket depth, bleeding index, plaque index,gingival index and mobility.
Results:Statistically significant differences between visits 1-4 were reported for all measurements: pocket depth, bleeding index, gingival index, and mobility (p≤0.05), except for plaque index (p=0.43). Comparison between control vs experimental teeth showed significant differences for bleeding index (p=0.026), gingival index (p=0.014), and mobility (p=0.00).
Conclusion: The results of the current study showed a clear association between deep traumaticoverbite with palatal impingement and the periodontal health of the upper anterior segment which indicate that traumatic overbite is a contributing factor in the development and pathogenesis of periodontal disease.In cases of deep overbite, using Hawley retainer with anterior bite plate can eliminate the gingival trauma and improve the general condition of the periodontium
