Resumo
A mensuração da força de mordida permite a avaliação da funcionalidade e da atividade do sistema estomatognático, sendo esta uma variável de grande importância para o cirurgião-dentista no estabelecimento do correto plano de tratamento e prognóstico das reabilitações orais. Os dinamômetros para medida de força manual são preditores de força global e apresentam acessibilidade técnica e financeira. O objetivo deste estudo foi estimar a correlação entre a força de preensão manual (FP) média e força máxima de mordida (FM) de indivíduos jovens dentados (G1), adultos dentados (G2) e desdentados totais usuários de próteses totais bimaxilares (G3) do sexo feminino. Após preencher o termo de consentimento livre e esclarecido, os participantes foram submetidos ao teste de mensuração da FP com o auxílio do dispositivo eletrônico digital na mão dominante e não dominante, um total de três mensurações para cada mão, para obtenção da média das mesmas. Posteriormente, através de um gnatodinamômetro digital, foi mensurada a FM na região de molar sendo considerada a média de três mensurações de cada lado. Foram calculados o Coeficiente de Correlação de Pearson (r) e Análise de Variância multivariada (MANOVA). Para comparação das médias, pós-teste de Tukey e de Games-Howell, a nível de significância de 5%. Observou-se uma correlação de moderada a forte entre as variáveis para todos os grupos: G1, G2 e G3 (r=0,838; 0,707; 0,643; respectivamente) e uma diferença significativa entre as médias de FM sendo G1>G2>G3 (p<0,05). Com relação à média de FP, o G3 se diferiu estatisticamente de G1 e G2, apresentando uma média significativamente inferior comparado aos demais grupos (p<0,05). Conclui-se que a existência da correlação entre FM e FP pode ser mais um método eficiente para o correto planejamento reabilitador oral.
The measurement of bite force allows the evaluation of the functionality and activity of the stomatognathic system, being a variable of great importance for the dentistry professionals in the establishment of the correct treatment plan for oral rehabilitations. Dynamometers for manual force measurement are predictors of global strength and have technical and financial accessibility. The aim of this study was to estimate the correlation between the average handgrip force (HF) and maximum bite force (BF) of young dentate (G1), dentate adults (G2) and female total edentulous users of bimaxillary total dentures (G3). After signed the consent form, the participants were submitted to the HF measurement test using the digital electronic device on both hands, three measurements for each hand, to obtain the average of the same ones. Subsequently, through a digital gnatodynamometer, BF was measured in the molar region and the average of three measurements on each side was considered. The Pearson Correlation Coefficient (r) and the Multivariate Analysis of Variance (MANOVA) were calculated. In order to compare the obtained average data, post-tests of Tukey and Games-Howell have been performed at a significance level of 5%. A moderate to strong correlation was observed among the variables for all groups: G1, G2 and G3 (r=0.838, 0.707, and 0.643, respectively) and a significant difference among the average BF data being G1>G2>G3 (p<0.05). Regarding the average of HF, G3 statistically differed from G1 and G2 (p<0.05), presenting a significantly lower average compared to the other groups. It has been concluded that the existence of the correlation between BF and HF can be another efficient method in order to favor oral rehabilitation planning.
