Abstract

Open bite is the absence of vertical overlap of lower incisors by upper incisors when posterior teeth are in occlusion. An anterior open bite can cause periodontal damage which leads to gingivitis and periodontitis. To assess the gingival health status in patients with anterior open bite and also compares with patients without an anterior open bite. Retrospective data collected from 89,000 case records from June 2019 to March 2020. The present study consisted of 76 patients divided into two groups: patients with anterior open bite and patients without an anterior open bite. In both groups, the following parameters were recorded - Oral Hygiene Index - Simplified (OHI-S) and Plaque Index (Silness and Loe). OHI-S index and plaque index was similar in patients with and without an anterior open bite. Mean Plaque Index for case group (patients with anterior open bite) is 0.76, and Mean Plaque Index for control group (patients without the anterior open bite) is 0.78. Mean OHI-S Index for case group (patients with anterior open bite) is 0.51, and Mean OHI-S Index for the control group (patients without the anterior open bite) is 0.53. The difference was not statistically significant (P-value > 0.05). In this study, gingival health status in patients with and without an anterior open bite is low.
