Introduction Maximum bite force (MBF) is the maximum force performed by the subject on the fragmentation of food, directly related with the mastication and determined by many factors. Objective Analyze the MBF of subjects according to age groups. Methods One hundred individuals from the city of São Paulo were equally divided according to age groups and gender. Each individual submitted to a myotherapy evaluation composed of anthropometric measurements of height and weight to obtain body mass index (BMI), using a tape and a digital scale (Magna, G-life, São Paulo), and a dental condition and maximum bite force evaluation, using a digital dynamometer model DDK/M (Kratos, São Paulo, Brazil), on Newton scale. The dental and bite force evaluations were monitored by a professional from the area. Analysis of variance was used with MBF as a dependent variable, age group and gender as random factors, and BMI as a control variable. Results Till the end of adolescence, it was possible to observe a decrease in MBF in both sexes, with the male force greater than the female force. In young adults, the female force became greater the males, then decreased in adulthood. There was no correlation between MBF and BMI. Conclusion There are MBF variations that characterizes the human development stages, according to age groups.
引言 最大咬合力（MBF）是受试者在食物破碎时所施加的最大力量，与咀嚼直接相关，并由多种因素决定。目的 根据年龄组分析受试者的最大咬合力。方法 从圣保罗市选取100名个体，根据年龄组和性别平均分组。每位个体都接受了肌功能治疗评估，包括使用卷尺和数字秤（Magna，G-life，圣保罗）测量身高和体重以获得体重指数（BMI），以及使用数字测力计DDK/M型号（Kratos，巴西圣保罗）在牛顿秤上进行牙齿状况和最大咬合力评估。牙齿和咬合力评估由该领域的专业人员进行监测。以最大咬合力作为因变量，年龄组和性别作为随机因素，体重指数作为控制变量，使用方差分析。结果 直到青春期结束，可以观察到男女的最大咬合力均下降，男性力量大于女性力量。在年轻成年人中，女性力量变得大于男性，然后在成年期下降。最大咬合力与体重指数之间没有相关性。结论 根据年龄组，存在表征人类发育阶段的最大咬合力变化。
