Exposição solar e risco ocupacional: Relação entre carcinoma de células escamosas em lábio, queilite actínica e displasia epitelial oral em militares e dependentes

Os militares são considerados um grupo de risco ocupacional para o desenvolvimento de queilite actínica (QA) e carcinoma de células escamosas de lábio (CCEL), devido ao desempenho de funções ao ar livre sob constante exposição aos raios solares ultravioleta (UV), sendo este o principal fator de risco destas doenças. Este trabalho tem como objetivo avaliar a relação entre QA e CCEL, associando a presença e o grau de gravidade da displasia epitelial oral (DEO) com o fator ocupacional em militares e dependentes, avaliar o fluxo de encaminhamentos para a Clínica de Estomatologia da Odontoclínica Central da Marinha (OCM). Foi realizado um estudo retrospectivo dos casos de QA ou CCEL diagnosticados no período de 2011 a 2023 na OCM e as variáveis coletadas foram: sociodemográfcas, ocupacionais, histórico de exposição solar, atividade militar, área anatômica acometida, presença e grau de DEO. A amostra foi composta por 89 (91,8%) casos de QA e 8 (8,2%) CCEL. Os militares representavam 83,1% dos casos de QA e 75% dos CCEL. Quanto à origem, 83,1% das QA e 62,5% dos CCEL procederam de encaminhamentos internos, da própria Organização Militar (OM). A DEO esteve presente em 72% das QA, não sendo observada associação estatisticamente signifcativa entre a exposição ocupacional com a presença e gravidade da DEO. Dois casos de CCEL tinham relato de QA prévia. Este estudo corrobora com os dados da literatura e demonstra a importância do Cirurgião-Dentista militar na prevenção e tratamento das doenças orais com risco ocupacional nas Forças Armadas.

Osteonecrosis of the jaws in patients under osteoporosis treatment: a nine-year experience report.

Objective: This study aimed to report the experience of medication-related osteonecrosis of the jaws (MRONJ) in osteoporotic patients for nine years, and their associated initiating factors. Materials and methods: The numbers of invasive oral procedures (IOP) (tooth extraction, dental implant placement, and periodontal procedures) and removable prostheses performed from January 2012 to January 2021 were obtained from the digital records of a large public dental center. There were an estimated 6,742 procedures performed in patients under osteoporosis treatment. Results: Two cases (0.03%) of MRONJ were registered in nine years amongst patients with osteoporosis who had dental treatment at the center. From the 1,568 tooth extractions, one patient (0.06%) developed MRONJ. There was also one case from the 2,139 removable prostheses delivered (0.05%). Conclusion: The prevalence of MRONJ associated with osteoporosis treatment was very low. The protocols adopted seem to be adequate for the prevention of this complication. The findings of this study reinforce the rare frequency of MRONJ associated with dental procedures in patients submitted to the pharmacological management of osteoporosis. An integral analysis of systemic risk factors and oral preventive strategies may be considered regularly in the dental treatment of these patients.

Periodontal management of a patient with chronic kidney disease: a case report

The association between periodontal disease and chronic kidney disease (CKD) has been recognized over the years. Gingival overgrowth may be a side effect of some of the drugs prescribed for patients with CKD. Objective: The objective of this manuscript was to report the dental management of a patient with chronic renal disease who presented periodontitis and gingival overgrowth. Case report: A 55 years old male patient sought dental treatment, and was diagnosed with generalized periodontitis in advanced stage and gingival overgrowth. The overgrowth was associated to the use of amlodipine, a longacting calcium channel blocker. The treatment consisted of interruption of amlodipine, sessions of oral hygiene instruction and basic periodontal therapy. Thereafter, conventional periodontal therapy, with scaling and root planning of the four hemiarches, surgical periodontal therapy and gingivectomy of the overgrowth were performed. Considering periodontal sites with a probing depth (PD) > 4mm at baseline, mean PD was reduced (baseline: 5.94 ± 1.80; follow-up: 2.76 ± 1.38), as well as mean clinical attachment loss (baseline: 5.55 ± 1.51; followup: 4.52 ± 1.47). Periodontal disease was controlled and there was no recurrence of gingival overgrowth after 18 months of follow-up. Conclusion: The management of the reported patient with CKD and periodontal involvement included discontinuation of amlodipine, basic and advanced periodontal therapy and gingivectomy. Proper oral hygiene may help to prevent recurrence of the gingival overgrowth and to maintain periodontal health.

Introdução: A associação entre doença periodontal e doença renal crônica (DRC) tem sido reconhecida nos últimos anos. O crescimento gengival excessivo pode ser um efeito colateral de alguns medicamentos prescritos para pacientes com DRC. Objetivos: O objetivo deste estudo foi relatar o manejo odontológico de um paciente com DRC que apresentava periodontite e aumento gengival. Relato do caso: Um paciente do sexo masculino, 55 anos, procurou atendimento odontológico e foi diagnosticado com periodontite generalizada em estágio avançado e crescimento gengival associado ao uso de anlodipina, um bloqueador dos canais de cálcio de ação prolongada. O tratamento consistiu em interrupção da anlodipina, sessões de instruções de higiene bucal e terapia periodontal básica. Posteriormente, foi realizada terapia periodontal convencional, com raspagem e alisamento radicular dos quatro hemiarcos, seguida de cirurgia periodontal a retalho e gengivectomia. Considerando os sítios periodontais com profundidade de bolsa à sondagem (PBS) > 4mm no início do tratamento, a média de PBS foi reduzida (início: 5,94 ± 1,80; final: 2,76 ± 1,38), bem como a média do nível clínico de inserção (início: 5,55 ± 1,51; final: 4,52 ± 1,47). A doença periodontal foi controlada e não houve recorrência do crescimento gengival após 18 meses de acompanhamento. Conclusão: O tratamento odontológico deste paciente com DRC e envolvimento periodontal incluiu a interrupção da anlodipina, terapia periodontal básica e avançada e gengivectomia. A higiene bucal adequada pode ajudar a prevenir a recorrência do crescimento gengival excessivo e a manutenção de um estado periodontal saudável.

Oral squamous cell carcinoma: clinicopathological features in patients with and without recurrence.

AIM: To compare the clinicopathological profile of oral squamous cell carcinoma (OSCC) in groups with and without recurrence. METHODS: Records of all patients who underwent surgery for primary OSCC at a single institution during 1999 were identified. Patient demographics, lesion site, clinical and pathologic stage, pathologic grading, pattern of invasion, lymphocytic infiltrate, perineural invasion, and treatment and survival data were collected. Descriptive statistics were calculated for each variable and survival was calculated using Kaplan-Meier and Cox models. Patients were divided into 2 groups: with (n = 25) and without (n = 28) recurrence. RESULTS: Tongue (p = 0.02) and poorly differentiated (p = 0.04) tumors were associated with recurrence. Kaplan-Meier and Cox models revealed tobacco use and the absence of lymphocytic infiltrate to be associated with the poorest survival in recurrent OSCC. CONCLUSION: The tumor site, tobacco use, and pathological features were involved in the recurrence of OSCC and should be taken into account for OSCC treatment and follow-up.
