Lateral Alveolar Ridge Augmentation with Autogenous Tooth Block Graft Compared with Autogenous Bone Block Graft:a Systematic Review

OBJECTIVES: The objective of the present systematic review was to evaluate the current knowledge of implant treatment outcome following lateral alveolar ridge augmentation with autogenous tooth block graft compared with autogenous bone block graft prior to implant placement. MATERIAL AND METHODS: MEDLINE (PubMed), Embase and Cochrane Library search in combination with hand-search of relevant journals was conducted including human studies published in English through December 20, 2021. Comparative and non-comparative studies assessing lateral alveolar ridge augmentation with autogenous tooth block graft were included. Quality and risk-of-bias assessment were evaluated by Cochrane risk of bias tool, Newcastle-Ottawa Scale and GRADE system. RESULTS: One comparative study characterized by low grade and two non-comparative studies fulfilled the inclusion criteria. No significant difference in short-term implant survival, health status of the peri-implant tissue or frequency of complications between the two treatment modalities was observed. Postoperative dimensional changes of the alveolar ridge width were significant diminished with tooth block compared with bone block (P = 0.0029). Consequently, the gain in alveolar ridge width was significantly higher with tooth block, after 26 weeks (P = 0.014). However, a higher frequency of short-term peri-implant mucositis was observed with tooth block. CONCLUSIONS: Lateral alveolar ridge augmentation with tooth block seems to be a suitable alternative to bone block. However, results of the present systematic review are based on short-term studies involving small patient samples. Further long-term randomized controlled trials are therefore needed before definite conclusions can be provided about the beneficial use of tooth block compared with bone block

PREVALÊNCIA DE MANIFESTAÇÕES ORAIS EM PACIENTES INFANTO-JUVENIS SUBMETIDOS À QUIMIOTERAPIA

Atualmente, 70% das crianças acometidas por câncer podem ser curadas, se diagnosticadas precocemente e tratadas em centros especializados. OBJETIVO: Registrar a prevalência das manifestações orais provocadas pela quimioterapia das doenças neoplásicas. METODOLOGIA: Foi realizado através de coleta de dados de prontuários de 162 pacientes que estiveram em tratamento quimioterápico, sendo 86 do sexo masculino e 76 do sexo feminino com idade entre 1 a 19 anos, e média de 8,39 anos (DP ± 4,81), onde foram observadas as principais manifestações orais como: mucosite, xerostomia, candidíase,e relacionadas com o gênero, idade, e tipo de tumor. RESULTADOS: As neoplasias mais encontradas foram as leucemias (35,8%), e as manifestações orais mais prevalentes foram a mucosite, candidíase e xerostomia, com índices de 37%; 6% e 6%, respectivamente. CONCLUSÕES: As leucemias foram as neoplasias que mais acometeram os pacientes

Buccal manifestations in patients submitted to chemotherapy

Several changes in the oral cavity due to chemotherapy can be observed and can lead to important systemic complications, increasing the time of the patient in hospital and the costs of the treatment as well as affect the quality of life of the patients. The aim of this study was to assess the oral manifestation in patients treated with chemoterapy according to sex, age and tumor type. Data was collected in an oncology hospital in Juiz de Fora, Minas Gerais State, from patients' records that were submitted to oncologic treatment. It was possible to verify that mucositis, associated or not to other type of lesions, was the most common lesion in both sex of all ages (15.5%). Xerostomia and other lesions, such as Candida infection and aphthous lesions, were also present. It is possible to improve the quality of life of the patient during and after anti-neoplastic therapies through a protocol of odontological assistance that includes changes of the oral environment previous to chemotherapy such as profilaxis, caries removal, treatment of periodontal and periapical lesions, oral hygiene instructions, diet orientation and laser therapy. It is very important the insertion of the dentist in the oncologic medical team for the early diagnosis of the oral manifestation and follow-up during treatment time.Em decorrência da quimioterapia, alterações na cavidade oral podem ser observadas e levar a complicações sistêmicas importantes, podendo aumentar o tempo de internação hospitalar, os custos do tratamento e afetar diretamente a qualidade de vida dos pacientes. Este trabalho teve como objetivo realizar uma pesquisa em um hospital de oncologia da cidade de Juiz de Fora (MG), sendo realizado através de coleta de dados nos prontuários de pacientes que estiveram em tratamento oncológico, onde foram avaliadas as prevalências das manifestações orais em relação ao sexo, idade e tipo de tumor. Verificou-se que a mucosite foi a manifestação mais incidente em ambos os sexos em todas as faixas etárias (15,5%). A xerostomia e as demais lesões, como candidíase e lesões aftosas, também estiveram presentes. É possível melhorar a qualidade de vida antes, durante e após as terapias antineoplásicas através de um protocolo de atendimento odontológico que inclua medidas de condicionamento do meio bucal prévia à quimioterapia, como profilaxia, remoção de cáries, tratamento periodontal e de focos periapicais, orientação para higiene oral e dieta, e ainda laserterapia. É importante a inserção do dentista na equipe oncológica para o diagnóstico precoce das manifestações bucais e acompanhamento no período de tratamento
