The aim of the present study was to investigate the prevalence of dentofacial deformities in an Indonesian cohort
compared with a Dutch cohort and to study the anthropological aspects of dentofacial deformities. The Indonesian
cohort included 36 male and 50 female patients from Bandung. The Dutch cohort included 1,003 male and 1,623
female patients from Amsterdam. The majority of the Indonesian cohort was less than 30 years old (93%)compared
with 61.5% of the Dutch cohort. The age distribution of 31-40 years consisted of more Dutch than Indonesian patients
(p<0.01). Mandibular prognathism with an open bite was the most prevalent deformity (46.5%) among the Indonesian
cohort with a mean age of 22.78 (SD;6.34). Mandibular deficiency was the least prevalent deformity (2.3%) with a
mean age of 31 (SD;12.73). In contrast, mandibular deficiency with a normal or low mandibular plane angle was the
most prevalent deformity (55.9%)among the Dutch cohort with a mean age of 30.48 (SD;1075)and mandibular
prognathism with an open bite was the least prevalent deformity (3.3%) with a mean age of 22.49 (SD;6.20). Compared
to the Dutch population, the Indonesian population consisted of more mandibular prognathism (p<0.01) and less
mandibular deficiency (p<0.01). In the Indonesian cohort, young patients seek orthognathic surgery most frequently to
correct a functional problem associated with mandibular prognathism with an open bite. It was concluded that the
greatest severity of dentofacial deformities that are observed in Southeast Asian patients.
