Epidemiologia do Padrão Face Longa em escolares do Ensino Fundamental do município de Bauru - SP

Abstract

Objective: This study aimed to classify and determine the prevalence of individuals with vertical alteration of facial relationships, according to the severity of discrepancy, especially individuals with long face pattern. Methods: The sample was composed of 5,020 individuals of Brazilian nationality, of both genders, aged 10 years to 16 years and 11 months, attending middle schools at the city of Bauru-SP, Brazil. Examination of facial morphology comprised direct observation of the face in frontal and lateral views, always with the lip at rest, aiming to identify individuals presenting vertical alteration of facial relationships. After identification, these individuals were scored, according to severity, into three subtypes, namely mild, moderate and severe. The prevalence of individuals with long face pattern considered only the individuals scored as subtypes moderate and severe. Results: There was prevalence of 34.94% of vertical alteration of facial relationships and 14.06% of long face pattern. Conclusions: The results obtained in this study revealed that the prevalence of vertical alteration of facial relationships and long face pattern was higher than that reported in the literature.

Estudo das características cefalométricas em adolescentes brasileiros portadores de Padrão Face Longa

“…It was inspired by previous research, which defined the cephalometric means of long-faced adult patients. 4,6 These data lay the groundwork for the discussion of these findings in adolescents.…”

“…The occlusal analysis showed that 71% of long-faced adult patients exhibit a Class II, Division 1 relationship. 6 This sagittal compensation was present only in mandibular incisors, whereas the upper incisors showed no difference in sagittal behavior between Long Face Pattern and Pattern I subjects.…”

“…This is due to difficulties in standardizing the magnitude of the excess to determine a long face. For example, the impact of increased LAFH in young Caucasian Americans is 18% 5,6 while in young Brazilians it is 35,00%. 8 When the diagnosis refers to the long face itself, probably with an indication for surgical correction, incidence drops to around 1.5% of the population.…”

“…8 When the diagnosis refers to the long face itself, probably with an indication for surgical correction, incidence drops to around 1.5% of the population. 6 The cephalometric characteristics are well defined for adult patients who are no longer in the growth phase, including Brazilians. 4 The literature also confirms that facial morphology is established at an early stage, 17,18,22 and the long face is no exception.…”

Facial pattern of patients with post-foramen incisor cleft

“…It is believed in extra-genetic etiology for cleft palate, although it has been mentioned that several genes are involved in the formation of palate. 11,18 The Hospital for Rehabilitation of Craniofacial Anomalies (HRAC-USP) set a routine therapy that establishes the performance of palatoplasty at 12 months old. It seems obvious the logic to reconstruct the morphology and then seek an adjustment of the functions developed by the nasopharyngeal system.…”
