Abstract
Purpose: The purpose of this study was to evaluate the influence of canine guidance inclination through periodontal pulsation.
Materials and Methods: The measurement was completed using a tooth displacement transducer consisting of a photo sensor. Two healthy adult dentate subjects volunteered for this study. Subject A was a non-bruxer while subject B had a history of bruxism. The periodontal pulsation of both subjects before and after clenching tasks were measured. To evaluate the effect of canine inclination on the periodontal pulsation, the lingual surface of subject A's left canine was modified by attaching two metal guidances, consecutively. Metal guidances inclined up to 10 and 20 degrees were prepared, set on the patient's canine and remained in the mouth overnight. The periodontal pulsation before and after clenching tasks were measured the next day.
Results: 1. No difference was found in the periodontal pulsation at rest of subjects A and B. The periodontal pulsation observed in Subject A was similar before and after clenching tasks. However, in subject B, the periodontal pulsation was different before and after clenching. 2. In subject A, the periodontal pulsation did not change by modifying the canine guidance inclination to 10 degrees. Conversely, a change was observed when the inclination was increased to 20 degrees. The periodontal pulsation curve observed was similar to that found in subject B (without canine modification).
Conclusions: From the results, the following conclusions were drawn: 1. Data indicates that it is possible to measure the periodontal pulsation of canine tooth. 2. Tooth guidance inclined up to 10 degrees is acceptable to the periodontal pulsation. 3. Tooth guidance inclined up to 20 degrees is inappropriate and not acceptable to the periodontal pulsation. This means that this inclination is detrimental to the integrity of the periodontal pulsation.
