Abstract Patients with mandibulofacial asymmetry will suffering from aesthetical, psychological, functional disturbance, and has a poor prognosis. The aim of the research was to get the prediction index through the study of risk factors for prevention and early detection. The study was conducted in several schools in Jakarta, on 234 Indonesian physical characteristics aged 8-30 years. Data were obtained from questionnaires and examinations (clinical, functional, photographic, and radiographic examinations). The main risk factor is One-sided Sleep Habit and Temporomandibular Joint Disorder Sign. It was detected that mandibulofacial asymmetry characterized a specific pattern of dental and skeletal morphology. Risk Factors Index and Model of Dentocraniofacial Morphological Pattern can be used to predict the occurrence of asymmetry mandibulofacial.

Received date: 26 June 2016 Accept date: 25 July 2016 Introduction Malocclusion is one of dental problems in Indonesia with high prevalence. Malocclusion could affect general health, oral and stomatognatic function, and psychological aspect due to esthetic problem. Preventive and rehabilitative actions for malocclusion case are complicating by many factors including mandibulofacial asymmetry. Malocclusion with mandibulofacial asymmetry give a worse prognosis. (1,2) Asymmetry is considered as a normal phenomenon, but will be a problem whenever it becomes a disturbance functionally and aesthetically, especially mandibular asymmetry. The most asymmetric patient complain is imbalance facial esthetics reasons. Recent study with large samples of 4,509 high school students in Korea showed that imbalanced tooth position reduced self-esteem. It was not only functional and aesthetical problem, Shackelford and Larsen from University of Michigan proved that facial asymmetry was one of indicators of psychological and emotional condition, as well as physiological problems, a similar result of Grammer and Thornhill research. (3,4,5) Prevention and early treatment of malocclusion with mandibulofacial asymmetry had not had a clear protocol yet. It was often unoticeable by general practitioners in the front line of prevention. Prevention should be given more attention by the health practitioners and national health system. World Health Organization (WHO) was paying attention on prevention so that it could be integrated to health system. If chronical diseases or abnormalities were not being prevented, health management in every country would have problem of high cost health system in 2020. Disease or abnormality prevention had high economic value. (6,7) For preventive effort, the most important step is to find etiology. Knowing the cause of asymmetry as the result of growth abnormality would open the window of management of malocclusion with mandibulofacial asymmetry.
