RESUMO
Abstract The use of cocaine and its main derivative, crack, can cause some systemic effects that may lead to the development of some oral disorders. Objective To assess the oral health of people with a crack cocaine use disorder and identify salivary protein candidates for biomarkers of oral disorders. Methodology A total of 40 volunteers hospitalized for rehabilitation for crack cocaine addiction were enrolled; nine were randomly selected for proteomic analysis. Intraoral examination, report of DMFT, gingival and plaque index, xerostomia, and non-stimulated saliva collection were performed. A list of proteins identified was generated from the UniProt database and manually revised. Results The mean age (n=40) was 32 (±8.88; 18-51) years; the mean DMFT index was 16±7.70; the mean plaque and gingival index were 2.07±0.65 and 2.12±0.64, respectively; and 20 (50%) volunteers reported xerostomia. We identified 305 salivary proteins (n=9), of which 23 were classified as candidate for biomarkers associated with 14 oral disorders. The highest number of candidates for biomarkers was associated with carcinoma of head and neck (n=7) and nasopharyngeal carcinoma (n=7), followed by periodontitis (n=6). Conclusions People with a crack cocaine use disorder had an increased risk of dental caries and gingival inflammation; less than half had oral mucosal alterations, and half experienced xerostomia. As possible biomarkers for 14 oral disorders, 23 salivary proteins were identified. Oral cancer and periodontal disease were the most often associated disorders with biomarkers.
RESUMO
Gingival smile is a term used to describe an aesthetic condition in which excessive gingival exposure at the jaw level occurs during smile. There are several factors related to its etiology, the most common is the altered passive eruption of anterior superior teeth. To correct this disharmony, a multidisciplinary approach is necessary, and the treatment plan depends on a correct diagnosis and assessment for a better prognosis. The present study aims to describe a clinical case where periodontal surgical techniques were used to correct this condition. Female patient, 25 years old, with aesthetic complaint of the amount of gum exposed when smiling and diagnosed with altered passive eruption. Clinical crown augmentation surgery was performed on the anterior superior teeth. After 1 and 2 years, periodontal clinical parameters (probing bleeding, probing depth, clinical attachment level, crown length, keratinized mucosa width and plaque index) were reassessed, through clinical examination, digital photographic monitoring and measurement tools. In two years, it was possible to note the stability of the results achieved, maintaining values similar to those of the immediate postoperative period. The case report confirmed the success of the clinical crown augmentation surgery and the periodontal parameters stability evaluated after 2 years. (AU)
Sorriso gengival é o termo utilizado para descrever uma condição estética em que ocorre uma exposição gengival excessiva ao nível da maxila, durante o sorriso. Há diversos fatores relacionados a sua etiologia, sendo a mais comum a erupção passiva alterada dos dentes ântero-superiores. Para correção dessa desarmonia é necessária uma abordagem multidisciplinar, sendo o plano de tratamento dependente de um correto diagnóstico e avaliação para um melhor prognóstico. O presente estudo tem objetivo de descrever um caso clínico onde técnicas cirúrgicas periodontais foram utilizadas para correção dessa condição. Paciente gênero feminino, 25 anos de idade, com queixa estética da quantidade de gengiva exposta ao sorrir e com diagnóstico de erupção passiva alterada. Foi submetida a cirurgia de aumento de coroa clínica nos dentes antero-superiores. Após 1 e 2 anos foram reavaliados os parâmetros clínicos periodontais (sangramento a sondagem, profundidade de sondagem, perda de inserção, comprimento da coroa, largura da mucosa queratinizada e índice de placa), através de exame clinico, acompanhamento digital fotográfico e ferramentas de medição de imagem. Em dois anos, foi possível constatar a estabilidade dos resultados alcançados, mantendo valores semelhantes aos do pós-operatório imediato. O relato de caso confirmou o sucesso da cirurgia de aumento de coroa clínica e a estabilidade dos parâmetros periodontais avaliados após 2 anos. (AU)
