An Evaluation of Maximum Occlusal Force in Endodontically Treated Teeth
Objectives: Understanding the relationship between endodontically treated teeth and sensitivity to masticatory load is important for managing the risk of tooth damage following pulp removal. The study aimed to compare the maximum occlusal force in endodontically treated teeth and their vital contralateral counterparts and to evaluate the factors affecting them.
Methods: Thirty adult participants presented with an endodontically treated tooth and its vital contralateral counterpart tooth were recruited, consisting of 15 males and females each. Maximum occlusal forces were measured using a wireless sensor network occlusal force recorder. Data were analyzed by comparing the mean maximum occlusal force of endodontically treated teeth and their vital contralateral counterpart. The intraoral clinical and endodontically-related factors were recorded and the association with maximum occlusal force was analysed using multiple factors ANOVA analysis.
Results: The mean maximum occlusal force for endodontically treated teeth was 215.44 ± 74.11N and 202.40 ± 70.67N for their vital contralateral counterpart. There was a statistically significant difference in the means of maximum occlusal force between the 2 groups (P < 0.001) using the paired sample t-test. The maximum occlusal forces of both groups were statistically significantly associated with the location of teeth and crown root ratio (P < 0.01). Results from a multiple factors ANOVA analysis for endodontically treated teeth revealed that the location of teeth was the key factor associated with the maximum occlusal force (P = 0.007). Endodontically treated anterior teeth had a significantly lower maximum occlusal force than premolars (P = 0.039) and molars (P < 0.001).
Conclusions: Endodontically treated teeth showed higher maximum occlusal force than the control group and the tooth location was the significant clinical factor affecting occlusal force. This highlights the importance of taking protective precautions and the importance of preserving the natural sensory and protective mechanisms of teeth.
