Decreased adaptive capacity of periodontium enhances susceptibility to injury from occlusal forces. This study aimed to identify the association between bone loss severity and signs of occlusal trauma in teeth with reduced periodontal support. Periodontal assessment, radiographic examination and relative maximum force in chewing movements using T-scan III occlusal analysis system were determined in 312 teeth from 15 periodontitis subjects, who received non-surgical periodontal therapy. Comparison of periodontal parameters and occlusal trauma indicators was performed between groups with and without > 60% proximal bone loss. The correlation was investigated among each assessed parameter and signs of occlusal trauma including fremitus, advanced tooth mobility and widened periodontal ligament space. Bleeding on probing, gingival recession and clinical attachment loss in the group with > 60% bone loss were more severe than those with less bone loss (p<0.05). Fremitus, advanced mobility, and widened periodontal ligament space were different between groups (p<0.05) although distribution of relative maximum force was not different. The extent of proximal bone loss was found to correlate with fremitus, advanced mobility, and widened periodontal ligament space at r= 0.219, 0.418, 0.318 respectively (p<0.05). In conclusion, all significant signs of occlusal trauma were significantly associated with > 60% proximal bone loss. [ABSTRACT FROM AUTHOR] |
