MIRANDA-ROSERO, Oswaldo Damián; PAREDES-HERRERA, María Eugenia  e  MOYANO-CARRERA, María Augusta. Use of botulinum toxin type A as a treatment for the gummy smile. Rev Ciencias Médicas [online]. 2023, vol.27, suppl.2  Epub 01-Dez-2023. ISSN 1561-3194.

Botulinum toxin is a deadly toxin produced by the gram-positive bacterium Clostridium botulinum. In dentistry, it is considered a substantial treatment for muscular hyperactivity that results in an unsightly characteristic such as the "gummy smile" in the patient. The present study was carried out with the aim of describing the use of botulinum toxin type A as a treatment for the aforementioned gummy smile. For this purpose, a search for information was carried out in the Scopus, ProQuest Health and Web of Science databases. The guidelines of the PRISMA declaration were used for its elaboration. It was concluded that the application of BoNTA reduces the contraction of the muscles responsible for elevating the upper lip, reducing gingival exposure, this being the least invasive, most effective, quickest and safest treatment for the patient, giving the patient a harmonious and visibly esthetic smile.
