RESUMO

Objective: 1) To critically review the published literature on applications of dental stem cells in the regeneration of intraoral tissues. 2) To provide an evidence-based level on research regarding application of dental stem cells in intraoral tissues regeneration. Methodology: This systematic review is conducted as per the JBI guidelines and reported as per the PRISMA. An initial literature search of papers published between 2004 and 2018 yielded 421 manuscripts. Nineteen studies satisfied the inclusion / exclusion criteria and were included for qualitative synthesis. Studies were categorized as animal (11) and human (8) trials. Five independent reviewers critically assessed the included studies. Risk of bias was assessed using SYstematic Review Centre for Laboratory animal Experimentation (SYRCLE) bias risk tool, robins-I tool for non-randomised clinical trial and Cochrane Collaboration's Tool for randomised clinical trial. Evidence levels were assessed based on JBI Criteria. Results: Animal trials mainly focused on periodontal regeneration. A high or unclear Risk of bias was more commonly found amongst animal studies. Laboratory, clinical and radiographic evaluation were used to assess the outcome. A total of Eight Human studies were conducted on a total samples size of 153 upon a wide age ranging from seven years to 60 years. Nearly 70% of the human studies used DPSC for regenerating alveolar bone defects. Conclusion: Appropriate well designed double-blind randomized clinical trials of longer duration are yet to be performed. Evidence for the included studies were 1C and 1D as per the JBI Criteria. Stem cell therapy demonstrated promising results in Periodontal tissue and alveolar bone regeneration. However, the number of studies to claim such a benefit are very limited (AU)

Objetivo: 1) Revisar criticamente a literatura publicada sobre aplicações de células-tronco dentárias na regeneração de tecidos intraorais. 2) Fornecer um nível baseado em evidências sobre pesquisas relacionadas à aplicação de células-tronco dentárias na regeneração de tecidos intraorais. Metodologia: Esta revisão sistemática é conduzida de acordo com as diretrizes do JBI e relatada de acordo com o PRISMA. Uma pesquisa bibliográfica inicial de artigos publicados entre 2004 e 2018 resultou em 421 manuscritos. Dezenove estudos satisfizeram os critérios de inclusão / exclusão e foram incluídos para síntese qualitativa. Os estudos foram categorizados como ensaios em animais (11) e humanos (8). Cinco revisores independentes avaliaram criticamente os estudos incluídos. O risco de viés foi avaliado usando a ferramenta de risco de viés do Centro de Revisão Sistemática para Experimentação com Animais de Laboratório (SYRCLE), a ferramenta robins-I para ensaios clínicos não randomizados e a Ferramenta da Colaboração Cochrane para ensaios clínicos randomizados. Os níveis de evidência foram avaliados com base nos critérios JBI. Resultados: Os ensaios em animais focaram principalmente na regeneração periodontal. Um risco alto ou pouco claro de viés foi mais comumente encontrado entre os estudos com animais. Avaliações laboratorial, clínica e radiográfica foram utilizadas para avaliar o resultado. Um total de oito estudos em humanos foram conduzidos em um tamanho total de amostras de 153 com ampla faixa etária, variando de sete a 60 anos. Quase 70% dos estudos em humanos usaram DPSC para regeneração de defeitos ósseos alveolares. Conclusão: Ensaios clínicos randomizados duplo-cegos apropriados e bem elaborados de maior duração ainda precisam ser realizados. As evidências para os estudos incluídos foram 1C e 1D de acordo com os critérios JBI. A terapia com células-tronco demonstrou resultados promissores na regeneração do tecido periodontal e do osso alveolar. No entanto, o número de estudos para reivindicar tal benefício é muito limitado (AU)

RESUMO

INTRODUCTION: About 4 million people are disabled by leprosy. Eighty-six percent of leprosy patients reside in Southeast Asia and Brazil. India accounts for up to 70% of total cases. In India, it is highest in West Bengal, Maharashtra, Uttar Pradesh, and Bihar. OBJECTIVE: The objective of the study is to assess the quality of life in terms of sense of coherence (SOC) among patients afflicted with leprosy in the state of West Bengal (located in eastern India on the Bay of Bengal). METHODOLOGY: A cross-sectional descriptive epidemiological study was conducted among estimated sample size of 350 participants who were afflicted with leprosy drawn from across the state of West Bengal, India. Data were collected on a specially designed pro forma. RESULTS: Most of the participants afflicted with leprosy were in the age group of 40-77 years, and there was predominance of males, with most of them belonging to the upper-lower socioeconomic class. On evaluating the incidence of extraoral lesions through ranking, facial nodules and facial spots were highest 182 (52%), while among intraoral lesions such as melanin pigmentation 176 (50%) and inflammatory papillary hyperplasia 150 (42.8%), was seen in greater fraction. The results of bivariate analysis between SOC and variables under investigation show that majority of the cases, i.e., 258 (47.14%) revealed the SOC interpretation as "poor." Statistical analysis showed significant difference in relation to age (P ≤ 0001) and socioeconomic status (P = 0.053) of participants. CONCLUSIONS: We conclude that 52% of the population were having facial nodules and facial spots and 50.2% of the population had intraoral manifestation such as melanin pigmentation. Analysis of SOC revealed that majority of the cases were interpreted as "poor."
