RESUMEN

OBJECTIVE: The present study aimed to assess the relationship between keratinized mucosa width and peri-implant diseases, namely peri-implant mucositis and peri-implantitis. MATERIALS AND METHODS: Ninety-one dental implants in function for ≥ 6 months from 40 partially or completely edentulous non-smoker subjects (24 females and 16 males) were evaluated clinically and radiographically. The width of keratinized mucosa, probing depth, plaque index, bleeding on probing, and marginal bone levels were assessed. Keratinized mucosa width was categorized as ≥ 2 mm or < 2 mm. RESULTS: There was no statistically significant association between keratinized buccal mucosa width and peri-implant mucositis or peri-implantitis (p ≥ 0.37). In the regression analysis, peri-implantitis was associated with longer implant function time (RR: 2.55, 95% CI: 1.25-11.81, p = 0.02) and implants in the maxilla (RR: 3.15, 95% CI: 1.61-14.93, p = 0.003). Mucositis was not associated with any of the factors analyzed. CONCLUSION: In conclusion, in the present sample, keratinized buccal mucosa width was not associated with peri-implant diseases, suggesting that a band of keratinized mucosa may not be necessary to maintain peri-implant health. Prospective studies are required to better understand its role in the maintenance of peri-implant health.

RESUMEN

Introduction: Sturge-Weber syndrome (SWS) is a rare condition characterized by facial capillary malformation, involves ocular, neurological, and cutaneous alterations. Associated with unilateral characteristic port-wine stains, gingival growth and purple-red coloration. Aim: his case aims to report dental treatment challenges in patients with SWS and importance of oral health maintenance in these individuals. Case report: a 20-year-old woman with an established diagnosis of SWS, presented bad breath and spontaneous gingival bleeding, with gingival growth and reddish-purple spots spread to labial and alveolar mucosa, tongue, and palate. Conditioning of the patient's oral environment by supra and subgingival scraping, dental unit extraction was performed. A conservative treatment plan was adopted for management adequacy of oral environment owing to possible complications inherent to the condition. Conclusion: it is important to emphasize the importance of dental surgeon's performance in relation to a multidisciplinary health team, as well as cooperation of patient, to obtain better results from the proposed therapy.

Introdução: a síndrome de Sturge-Weber (SSW) é uma condição rara caracterizada por malformação capilar facial, envolve alterações oculares, neurológicas e cutâneas. Associada a manchas unilaterais características do vinho do porto, crescimento gengival e coloração vermelho-púrpura. Objetivo: este caso tem como objetivo relatar desafios do tratamento odontológico em pacientes com SSW e a importância da manutenção da saúde bucal nesses indivíduos. Relato de caso: paciente do sexo feminino, 20 anos, com diagnóstico estabelecido de SSW, apresentou mau hálito e sangramento gengival espontâneo, com crescimento gengival e manchas roxas avermelhadas espalhadas pela mucosa labial e alveolar, língua e palato. Condicionamento do ambiente oral do paciente por raspagem supra e subgengival, foi realizada extração da unidade dental. Foi adotado um plano de tratamento conservador para adequação do manejo do ambiente bucal devido a possíveis complicações inerentes à condição. Conclusão: é importante enfatizar a importância do desempenho do cirurgião-dentista em relação a uma equipe multidisciplinar de saúde, bem como a cooperação do paciente, para obter melhores resultados com a terapia proposta.
