ABSTRACT
O sorriso gengival caracteriza-se pela exposição de 3 mm ou mais de gengiva ao sorrir. Para o paciente, pode gerar incômodo e, com isso, abalar sua autoestima e seu estado emocional. A perfeição de um sorriso não está apenas associada à coloração dos dentes, mas também à harmonia dos dentes, da gengiva e dos lábios. Quando a aplicação de toxina botulínica é associada ao procedimento cirúrgico, torna-se vantajosa, com a redução da exposição gengival sem a necessidade de outra intervenção cirúrgica. O propósito deste artigo foi relatar o caso de uma paciente que foi submetida à gengivoplastia associada à aplicação de toxina botulínica tipo A, para correção do sorriso gengival. A associação das técnicas se mostrou uma alternativa segura e efetiva no tratamento de correção do sorriso gengival.
Gummy smiles are observed when 3 mm or more gingival tissue is exhibited. For patients, it can be considered annoying at smiling, and interfere with his/her self esteem. Perfection of a smile is not just linked to dental color and shape, but to the harmony of teeth, gums and lips. Botulinum toxin associated to gingivoplasty is a promissing approach, once there is no need for a second surgical intervention to reduce gum exhibition. The aim of this paper is to report a case of gingivoplasty associated to botulinum toxin to manage a patient gummy smile. It was observed that the association of both techniques presented as a safe effective approach to treat gummy smile in cases of excessive maxilla.

PURPOSE: Postoperative intraperitoneal adhesions (PIAs) are one of the most important problems surgeons have to face after laparotomies. In this study, we aimed to evaluate the effectiveness of local application of botulinum toxin type A (BoNT-A) in various dosages on the prevention of intra-abdominal adhesions in rats with experimental intra-abdominal adhesions. METHODS: Forty Wistar Albino female rats were randomly separated into 4 groups. The 4 groups were determined as follows: Control (group 1, n = 10); Sham (group 2, n = 10); 10-µg/kg low-dose BoNT-A (group 3, n = 10) and 30-µg/kg high-dose BoNT-A (group 4, n = 10). Subserosal injuries were created on the caecum of all rats. Laparotomy was performed on the fifth day. Adhesion scores, histopathological examination, and E-cadherin expression levels were evaluated. RESULTS: General adhesion scores for groups 1 and 2 were determined to be significantly high when compared to group 4 (P < 0.001). A significant difference was also determined between groups 3 and 4 in terms of general adhesion scores (P < 0.05). In pair comparisons, a significant decrease in high-dose BoNT-A group (group 4) when compared to groups 1 and 2 in terms of neovascularization, fibroblast density, collagen deposition and inflammatory cell count was determined (P < 0.05). CONCLUSION: A significant decrease was observed only in postoperative PIAs in the high-dose BoNT-A group between all 4 rat-groups with experimentally created postoperative PIAs. In this study, high-dose BoNT-A is determined to be an effective agent in preventing postoperative PIAs.
ABSTRACT
Introduction:The gummy smile is characterized by a marked gingival exposure on smiling and it has been considered as one of the main complaints of patients, also influencing on self-esteem and social relationship. The development of new techniques such as botulinum toxin application may be a more conservative treatment option than surgical intervention (myectomy and Le Fort I osteotomy) in the treatment of gummy smile. Objective: To present the case of a patient who presented dental-gingival discrepancy and gummy smile, treated by gingival resection surgery and complemented by the application of botulinum toxin. Case report: A female patient, 23 years old, presented dental-gingival discrepancy and gummy smile, treated by gingival resection surgery and complemented by the application of botulinum toxin. Results: The gingival resection surgery promoted improvement of dental relationship, caused by increase of dental zenith and the application of botulinum toxin caused uniform dehiscence of the upper lip, increasing the harmony of the smile and improving self-esteem and quality life. Conclusion: Botulinum toxin is an additional option in the cosmetic improvement of the smile and gives better results when combined with gingival resection surgery.
ABSTRACT
Objective To investigate the plastic surgery of facial soft tissue for improvement of facial contour. Methods Botulinum toxin type A was injected into hypertrophied masseter to make it atrophy and attenuation; meanwhile, buccal fat lining was partly resected by intra-oral approach. Buc-cal liposuction was performed if necessary. Results 36 cases got satisfactory face thinning results af-ter treatment. The facial contour of all patients was markedly improved. Following up for 6 - 12 months showed that the effect was stable. Conclusion Plastic repair of facial soft tissue for improve-ment of facial contour is a simple approach, with mild injury, quick recovery, safe and effective.
