Objective:
To assess the association between secondary trauma from occlusion and the severity of periodontitis.
Method And Materials:
A total of 288 subjects with chronic periodontitis of varying severity and 93 healthy subjects were included in the study. Premature and balance contacts were identified by manual palpation and visualization of occlusal contacts during clenching in habitual intercuspation and lateral or protrusive movements of the mandible. Statistical analysis was performed with Kruskal-Wallis, Mann-Whitney, and Spearman correlation tests.
Results:
Statistically significant differences (P<.001) were found for all variables tested (ie, the total amount of trauma per patient and the number of premature and balance contacts increased significantly with the level of clinical attachment loss). The Spearman test showed a statistically significant correlation between the total amount of trauma per patient and the severity of periodontitis (P<.001).
Conclusion:
The results of this study indicate that secondary trauma from occlusion (ie, premature and balance contacts) is frequently seen in periodontally compromised patients and is positively correlated with the severity of attachment loss.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
