The lingual brake is an important structure for the musculoskeletal growth of the baby's jaws, inuencing the act of sucking, speaking and feeding.
There is an alteration called ankyloglossia (Ankylos: Linked and Glossa: Tongue), dened as a congenital malformation that alters mobility and
lingual function. Brake change occurs when a portion of the tissue that should have suffered apoptosis during embryonic development remains on
the underside of the tongue, restricting its movement. The lingual brake is formed by a connective tissue rich in elastic bers, lined with nonkeratinized stratied paved epithelium, containing adipose cells, muscle bers and blood vessels. Any anatomical or functional brake deciency
can have an impact on functions based on their severity. Its diagnosis is not difcult, as it is very visible and can be done through the "Tongue Test".
Surgical removal of the brake is necessary when it causes gingival retraction, diastema, hindering orthodontic, speech therapist, prosthetic and
aesthetic treatment. It is advisable to wait for the individual's growth process, especially between 6 months and 6 years of life. The treatment
performed for this anomaly is the frenectomy, which consists in the complete removal of the brake insert. The objective of the present study was to
conduct a research that evaluated the lingual brake of children, and the need for surgical treatment at the pediatric dentistry clinic at Amazon
Faculty - IAES through a questionnaire. It was a cross-sectional, descriptive and observational study, which evaluated the lingual brake of children.
Data were analyzed quantitatively and qualitatively using the statistical data program. The software used for data analysis was Epi Info version
7.2.2.6 for windows. It was concluded that of the 50 lingual brakes evaluated, 14% presented alteration, with a preference for females. It was clear
the need for an early diagnosis, besides the need for a multidisciplinary team
