Avaliação clínica e classificação do freio labial superior de crianças na primeira infância

Abstract

Objective: The objective of this study was to evaluate and classify the upper labial frenum of children aged zero to five years treated at the Pediatric Dentistry clinics of the Dental Hospital of the Federal University of Uberlândia and to collect data related to breastfeeding and parental perception of its interference in breastfeeding, aesthetics, and phonetics. Materials and methods: Two researchers evaluated and classified, according to Kotlow and Sewerin, the upper labial frenum of 102 children, separated into groups according to age range: group A from 0 to 12 months, group B from 13 to 24 months, group C from 25 to 36 months, and group D over 36 months. Results: A higher prevalence of Kotlow class IV frenum was observed, mainly in group A, and changes in the level of insertion of the frenum between age groups. In the Sewerin classification, 21 (20%) of the frenums had abnormalities, with persistent labial tectonomegaly being the most prevalent and most present in class IV. Forty-nine (48%) of the children were exclusively breastfed, and there was no relationship between palatal insertion of the upper labial frenum or the presence of anomalies and difficulties in breastfeeding. 53.9% of guardians believed that this structure interferes in some way, and 5 (4.9%) had already received an indication for surgical intervention. Conclusion: The degree of frenum insertion decreased with age. Breastfeeding was predominant in class IV infants in group A. Most parents believed that the upper labial frenum can interfere in some way.
