Bite force measurement in children with primary dentition

Abstract Biophysics is rarely mentioned as one of the most useful parts of dental and medical students' curricula. However, with growing complexity of tools and methods used in diagnostics and therapy, the knowledge of their physical foundations becomes important and helps with choosing the optimal solutions for both, a patient and a doctor. The aim of the proposed activity is to develop students' intuition about simple physical models that help with understanding fundamental properties of temporomandibular joint (TMJ). A simple device, which allows for bite force measurement, is proposed. It is based on beam bending and a strain gauge Wheatstone bridge circuit, mounted on two connected arms: the stiff one and the more elastic one. Linear regression is the only mathematical concept needed for understanding the physical background of the proposed activity. During the proposed activity - measuring of bite force for incisors, premolars and molars - students are confronted with basic concepts, such as lever, torque, electrical circuit, calibration curve. By utilizing a simple idea, instead of a commercially available device, students can understand where the data come from. Proposed system delivers physiologically reasonable results.

The Relationship

Objective: To better understand the relationship between malocclusion and masticatory and salivary functions in the primary dentition, the aim was to evaluate the differences in masticatory performance (MP), facial morphology (FM), maximal bite force (BF) and salivary parameters in 65 preschool children with normal occlusion (n = 22), functional posterior crossbite (n = 20) and anterior open bite (n = 23), and to explore the relationship between these variables. Material and Methods: MP, FM and BF were assessed by sieving method, anthropometry and gnatodynamometer, respectively. Stimulated (SS) and unstimulated (US) saliva flow and composition were measured by automated colorimetric technique. Data were analyzed using ANOVA/Kruskal-Wallis, t-test/Wilcoxon and Pearson/Spearman correlation test. The relationship between SS flow rate and the independent variables were assessed using multiple linear regression. Results: The lower face dimension was smaller in crossbite-group, and a decreased BF in the crossbite-side of the dental arch was observed. BF correlated positively with intergonial width in open bite group. In malocclusion groups, better MP correlated with byzigomatic and intergonial widths. US flow rate was lower in crossbite-group and total protein concentration differed between SS and US saliva only in the crossbite-group, being lower in US. Amylase activity was higher in SS than US in all groups. SS flow rate related positively with age and negatively with the presence of malocclusion. Conclusion: In young subjects, significant correlations were found between masticatory parameters and facial dimensions; in addition, some important masticatory and salivary parameters differed between children with different morphological occlusions, hence the importance of the early assessment of these parameters.KEYWORDS Bite Force; Dental Occlusion; Masticatory System; Primary Dentition.

Masticatory System

Maximum voluntary bite force is an indicator of the functional state of the masticatory system and the level of maximum bite force results from the combined action of the jaw elevator muscles modified by jaw biomechanics and reflex mechanisms. The measurement of bite force can provide useful data for the evaluation of jaw muscle function and activity. It is also an adjunctive value in assessing the performance of dentures. Technological advances in signal detection and processing have improved the quality of the information extracted from bite force measurements. However, these measurements are difficult and the reliability of the result depends on a number of factors, such as presence of pain and temporomandibular disorders, gender, age, cranio-facial morphology, and occlusal factors. In addition to these physiological factors, recording devices and techniques are important factors in bite force measurement. Therefore, one should be careful when comparing the bite force values reported in the research. (Eur J Dent 2010;4:223-232)
