INVERNIZZI-MENDOZA, Carlos Rafael et al. Frequency of sagittal and transverse malocclusions in students from 12 to 18 years of age in Asunción. Mem. Inst. Investig. Cienc. Salud [online]. 2020, vol.18, n.3, pp.17-23. ISSN 1812-9528.

Malocclusion is one of the most common oral disorders. Recognizing its importance leads to the need for epidemiological studies whose results guide the development of programs for its prevention, interception and treatment. The objective of the present investigation was to determine the frequency of malocclusion in the sagittal and transverse direction in secondary school students from the city of Asunción. A descriptive cross-sectional study was carried out. The study population was made up of students from 12 to 18 years old enrolled in public and private schools in the city of Asunción during 2017. The data collected from the oral inspection was recorded in clinical records and analyzed with the Epi-Info program. TM. The number of participants was 1047 students who met the inclusion criteria. Fifty two percent of the participants were female and 48% male. The frequency of malocclusion in the sagittal direction was 98%, and in the transverse direction it was 27.6%.Among sagittal malocclusions, the most frequent was Class I (53%). The frequency of crossbite was 23%, of which 43% presented an anterior crossbite and 57% a posterior crossbite. Of those who presented posterior crossbite, 61% were unilateral and 39% bilateral. An important frequency of malocclusions is observed in the study population indicative of the need of establishing actions for its timely diagnosis and treatment.
