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.

4 ~ 6岁儿童龋齿与非龋齿初级牙列磨牙咬合力的评价

目的:研究4 ~ 6岁有和无龋儿童的最大磨牙咬合力。材料与方法:本横断面研究于2018年5月至2018年12月进行。从印度金奈市6所不同的小学随机抽取4 ~ 6岁儿童288名，根据有无龋齿分为两组，每组144名儿童:A组牙列无龋齿儿童和B组牙列有龋齿儿童。采用标准化定制的咬合力计进行咬合力测量。采用统计学分析:数据以均数±标准差表示。采用学生t检验(双尾，独立)和方差分析来发现组间研究参数的显著性。结果:非龋牙列的咬合力(367.94±33.71N)高于龋牙列(326.73±27.83N)，差异有统计学意义(p≤0.01)。男孩的整体咬合力(350.44±35.84N)明显高于女孩(344.22±38.25N)。磨牙的咬合力最高(380.54±27.36N)，其次是近端磨牙(350.82±22.25N)和远端磨牙(310.63±20.82N)。结论:4 ~ 6岁儿童无龋牙列的咬合力明显高于龋牙列。男孩比女孩有更高的咬合力，磨牙平面排列比中、远阶磨牙排列有更高的咬合力。
