Objetivo: Esta revisão sistemática tem como objetivo avaliar a eficácia dos métodos ópticos de oximetria pulsátil e de fotopletismografia para avaliação da vitalidade pulpar, em comparação com os métodos convencionais de teste da sensibilidade pulpar no diagnóstico endodôntico.
Materiais e métodos: A pesquisa bibliográfica foi realizada nas bases de dados PubMed, Cochrane Library e Science Direct, considerando estudos publicados a partir do ano 2000 até ao presente. Foram incluídos pacientes adultos com boa saúde geral, sem doença periodontal, sem traumatismo dentário, sem cárie e sem restaurações extensas nos dentes testados. Os critérios de exclusão abrangeram estudos de revisão sistemática, meta-análises, testes in vitro, teses de dissertação, estudos em animais e pacientes com traumatismo dentário, cáries, tratamento endodôntico ou restaurações extensas. O risco de viés foi avaliado com a ferramenta QUADAS-2.
Resultados: Todos os estudos analisados demonstraram resultados positivos na deteção do nível de saturação de oxigénio nos dentes vitais. Os estudos comparativos não apresentaram uma diferença estatisticamente significativa entre o nível de oxigenação dos dentes testados e os índices de cada paciente. No entanto, de forma geral, o nível de oxigenação era mais elevado nos dedos indicadores dos pacientes do que nos dentes. Para a determinação da vitalidade pulpar, a oximetria pulsátil apresentou melhor sensibilidade e especificidade em comparação com os testes convencionais.
Conclusão: A oximetria pulsátil é uma ferramenta promissora para o diagnóstico da vitalidade pulpar. A melhoria da precisão permite ajustar o plano de tratamento e pode evitar procedimentos invasivos que teriam sido realizados apenas com base nos testes de sensibilidade convencionais. No entanto, alguns fatores que influenciam os resultados devem ser avaliados e aperfeiçoados.
Objective: The aim of this systematic review was to evaluate the effectiveness of optical pulse oximetry and photoplethysmography methods for assessing pulp vitality compared to conventional methods for testing pulp sensitivity in endodontic diagnosis. Materials and methods: The bibliographic search was carried out in the following databases: PubMed, Cochrane Library, and Science Direct, from 2000 to the present day. Adult patients in good general health, with no periodontal disease, no dental trauma, no caries, and no extensive restorations on the tested teeth were included. The exclusion criteria were systematic reviews, meta-analyses, in vitro studies, theses, animal studies, and patients with dental trauma, caries, endodontic treatment, or extensive restorations. The risk of bias was assessed using the QUADAS-2 tool. Results: All studies showed positive results for detecting the level of oxygen saturation in vital teeth. The comparative studies did not show a statistically significant difference between the oxygenation level of the tested teeth and the indices of each patient. However, in general, the oxygenation level was higher in the patients' index fingers than in their teeth. Better sensitivity and greater specificity were also demonstrated with pulsatile oximetry in determining pulp vitality compared to conventional tests. Conclusion: Pulsatile oximetry is a promising tool for diagnosing pulp vitality. Improved accuracy allows for better treatment planning and may prevent invasive procedures that would otherwise be performed using only conventional sensitivity tests. However, some factors influencing the results should be assessed and improved.
