Abstract(s)
Objetivos: O objetivo da investigação é medir as alterações da exposição gengival durante o sorriso e no lábio branco durante o repouso, após a realização de preenchimento com ácido hialurónico ao nível da fossa canina, a uma população de pacientes com critérios previamente selecionados na Clínica Dentária Egas Moniz.
Materiais e métodos: Este estudo inclui a aplicação controlada de ácido hialurónico a oito pacientes previamente selecionados cujo sorriso corresponde às definições: sorriso gengival/linha do sorriso alta. Para o registo das alterações, foram realizadas fotografias extra-orais padronizadas antes e 15 dias após o procedimento e, em simultâneo, foram documentadas medições precisas em 6 pontos em sorriso máximo (zénite gengival dos dentes #13, #12, #11, #21, #22 e #23) e em 3 pontos em repouso (asa do nariz esquerda, base do nariz e asa do nariz direita). De seguida, procede-se à análise de dados através do teste T-Student (p-value < 0,05), para determinar se o ácido hialurónico é eficaz na diminuição da exposição gengival e a sua validade como procedimento estético.
Resultados: Foram observadas diferenças estatisticamente significativas na exposição gengival de todos os dentes e entre os diferentes pontos do sorriso em sorriso máximo, assim como na medição da asa do nariz esquerda e direita em repouso, porém não foram encontradas diferenças estatisticamente significativas na medição da base do nariz.
Conclusões: Este estudo demonstrou que o preenchimento com ácido hialurónico é uma abordagem eficaz na correção temporária do sorriso gengival, com resultados que indicam uma redução significativa na exposição gengival e uma melhoria estética notável, podendo ser considerado como uma alternativa menos invasiva aos métodos cirúrgicos tradicionais utilizados na correção do sorriso gengival.
Aim: The aim of the research is to measure the alterations in gummy exposure while smiling and white lip at rest, after hyaluronic acid filler injections in the canine fossa area, in a population of patients with pre-selected criteria at the Clínica Dentária Egas Moniz. Materials and methods: This study includes the controlled application of hyaluronic acid to eight pre-selected patients whose smile corresponds to the following definitions: gummy smile/high smile line. To record the alterations, standardized extra-oral photographs were taken before and 15 days after the procedure, and, at the same time, precise measurements were documented at 6 points during maximum smile (gingival zenith of teeth #13, #12, #11, #21, #22, and #23) and at 3 points at rest (left nasal ala, nasal base, and right nasal ala). Subsequently, data analysis is performed using the T-Student test (p-value < 0,05), to determine whether hyaluronic acid is effective in reducing gummy exposure and its validity as an aesthetic procedure. Results: Statistically significant differences were observed in the gummy exposure of all teeth and between diferent smile points during maximum smile, as well as in the measurement of the left and right nasal ala at rest. However, no statistically significant differences were found in the measurement of the nasal base. Conclusions: This study demonstrated that hyaluronic acid filler is an effective approach for temporary gummy smile correction, with results indicating a significant reduction in gummy exposure and a remarkable aesthetic improvement. It can be considered a less invasive alternative to traditional surgical methods used in gummy smile correction
