Abstract

Objetive: The aim of the study was to evaluate the maximum molar bite force in children aged 4 to 6 years with and without dental caries.
Material and Methods: This cross sectional study was carried out from May 2018 to December 2018. A total of 288 children aged between 4 to 6 years were randomly selected from six different primary schools in Chennai city, India and divided into two groups of 144 children each, based on the presence and absence of caries: Group A children with non-carious dentition and Group B children with carious dentition. Bite force measurement was performed using standardized custom made occlusal force gauge.
Statistical analysis used: Data were expressed as the mean ± SD. Student’s t‑test (two tailed, independent) and ANOVA were used to find the significance of study parameters between the groups.
Results: Occlusal bite force of non-carious dentition (367.94 ±33.71N) was higher than the carious dentition (326.73±27.83N) and it was statistically significant (p≤0.01). Overall occlusal bite force of boys (350.44±35.84N) was significantly higher than that of girls (344.22±38.25N). Flush terminal plane molar relationship showed higher occlusal bite force (380.54±27.36N) followed by mesial step (350.82±22.25N) and distal step (310.63±20.82N) molar relationship.
Conclusion: Non-carious dentition showed significantly higher bite force than carious dentition in children 4 to 6 years of age. Boys had higher bite force than the girls and flush terminal plane molar relationship showed higher bite force than mesial and distal step molar relationship.
