Abstract

Malocclusion can be caused by dentocraniofacial growth abnormalities. These growth abnormalities can be caused by dental, maxillary and/or mandibular conditions (skeletal), acombination of dental and jaw (dentoskeletal). Many factors can influence this growth, including theresult of genetic, congenital and environmental. One example that plays an important role is therole of soft tissue or muscles. Aim: To investigate the association between masticatory muscle toneand dental and malocclusion class I and class III skeletal in Javanese ethnic patients.This study was analytical observational study with cross sectional and total sampling method inOrthodontics Clinic, Faculty of Dental Medicine, Universitas Airlangga Surabaya. In this study, therewere 18 patients with class I or malocclusion class III skeletal malocclusion with an age range of18-21 years in both sexes. Measurement of muscle tone in patients with class I and class IIIskeletal malocclusion using a surface electromyography on the temporalis, masseter andsuprahyoid muscles. The correlation test between masticatory muscle tone and dental and skeletalmalocclusions was analyzed using spearman's analysis (p>0.05).It was found that the muscles that significantly affected the malocclusion were the righttemporalis muscle, left temporalis muscle, right masseter muscle, left suprahyoid muscle, and rightsuprahoyid muscle. There was a strong relationship between suprahyoid muscle tone and class IIImalocclusion (p>0.05).Weak
