■咬力是咀嚼临床状态及其效率的重要指标。使用味觉测力计测量咬力是评估咀嚼系统生物力学特性的可靠方法。它随不同的地理种群以及生理和环境因素而变化。
■估算海得拉巴市上学儿童在不同牙列时期的最大咬合力(MOBF),并与不同的变量相关联。
■根据选择标准,总共选择了392名3-13岁的学龄儿童(男性214名,女性178名)。它们是根据牙列期进行划分的。人口统计细节以及身高等一般物理参数,体重,和最大张口(MMO)记录在预先设计的形式中。使用数字咬合力仪器测量最大咬合力。
■在3-5岁的原发性牙列中,最大咬合力(MOBF)为18.04N,6-11岁的混合牙列为47.64N,12-13岁的恒牙列为108.39N。观察到咬合力的大小与年龄成正比,高度,体重,和牙列期。在所有三个牙列中,男性的咬合力均大于女性。然而,仅在混合牙列中差异显着(p<0.05)。在所有牙列中,恒牙列的咬力明显更高。在原发性和混合性牙列中,咬力与体重指数(BMI)成反比,但与永久性牙列呈正相关。与女性相比,男性的平均MMO略高。它随着牙列阶段的增加而增加。
■咬力是多因素的。它与影响咬合力值的生理和形态因素具有显着相关性。

UNASSIGNED: Bite force is an important indicator of the clinical state of mastication and its efficiency. Bite force measurement using a gnathodynamometer is a reliable method to assess the biomechanical properties of the masticatory system. It varies with different geographic populations and physiological and environmental factors.
UNASSIGNED: To estimate the maximum occlusal bite force (MOBF) in school-going children of Hyderabad city at different dentition periods and to correlate with different variables.
UNASSIGNED: A total of 392 school-going children in the age range of 3-13 years were selected following selection criteria (214 males and 178 females). They were divided on the basis of the dentition period. Demographic details along with general physical parameters such as height, weight, and maximum mouth opening (MMO) were recorded in a predesigned proforma. Maximum bite force was measured using a digital bite force instrument.
UNASSIGNED: Maximum occlusal bite force (MOBF) was 18.04 N in primary dentition of age 3-5 years, 47.64 N in
mixed dentition of age 6-11, and 108.39 N in permanent dentition of age 12-13 years. The magnitude of bite force was observed to be directly proportional to age, height, weight, and dentition period. Males had greater bite force than females in all three dentitions. However, the difference was significant only in
mixed dentition (p < 0.05). Of all the dentition bite force was significantly higher in permanent dentition.Bite force showed an inverse relation with body mass index (BMI) in primary and
mixed dentition but a positive correlation was seen with permanent dentition. The mean MMO in males was slightly higher when compared to females. It increased with an increase in the dentition stage.
UNASSIGNED: Bite force is multifactorial. It has a significant correlation with physiologic and morphologic factors that influence the values of bite force.
