RFA and Bite Force in COD Teeth

Eskisehir Osmangazi University17 enrolled

Overview

This study aims to evaluate the periodontal attachment and ankylosis status of teeth associated with cemento-osseous dysplasia (COD). Using resonance frequency analysis (RFA) and a bite force sensor, the stability of COD-associated teeth was measured and compared with contralateral healthy teeth. These non-invasive and objective methods are expected to reveal the impact of COD lesions on the surrounding dentoalveolar structures.

Cemento-osseous dysplasias represent the most common group of benign fibro-osseous lesions, frequently detected in the mandible and often asymptomatic. Although they generally do not require treatment, the remodeling of bone and cementum-like tissues around the tooth roots has clinical significance in terms of periodontal attachment and ankylosis. The present study aims to investigate the ankylosis status of teeth associated with COD lesions at different stages by using objective measurement tools. In each patient, COD-associated teeth and contralateral healthy teeth were evaluated. Measurements were performed using resonance frequency analysis (RFA) with the Osstell™ device and additionally by a bite force sensor to assess functional stability. For RFA, SmartPeg magnetic attachments were fixed to the occlusal surface with composite resin, and three measurements were obtained in both mesio-distal and bucco-lingual directions. Mean ISQ values were then recorded. After measurements, SmartPeg was carefully removed without leaving residues, and patient comfort was evaluated using a six-point numeric rating scale. The obtained RFA and bite force values will be statistically analyzed to compare COD-associated teeth with healthy controls. Furthermore, the study seeks to determine differences in ankylosis tendency across various COD stages and their potential impact on periodontal ligament integrity. This approach may provide valuable insights for understanding the clinical course of COD and for planning surgical interventions in symptomatic cases

Resonance frequency analysis performed with the Osstell™ device. SmartPeg was attached with composite resin to the occlusal surface of the tooth, and ISQ values were recorded in mesio-distal and bucco-lingual directions.

Bite Force SensorDIAGNOSTIC_TEST

Assessment of maximum bite force using a bite force sensor. Measurements were performed on COD-associated teeth and contralateral healthy controls for comparison.

Outcomes

Primary Outcomes

Implant Stability Quotient (ISQ) values by Resonance Frequency Analysis (RFA)

Time frame: At baseline (single measurement per tooth)

Secondary Outcomes

Maximum Bite Force

Bite force recorded with a bite force sensor to compare functional stability of COD-associated teeth and contralateral healthy teeth.

Time frame: At baseline (single measurement per tooth)
