BackgroundSickle cell disease is the most common single gene disorder and the commonest haemoglobinopathy found with high prevalence in many populations across the world. Management of dental complications in people with sickle cell disease requires special consideration for three main reasons. Firstly, dental and oral tissues are affected by the blood disorder resulting in several oro-facial abnormalities. Secondly, living with a haemoglobinopathy and coping with its associated serious consequences may result in individuals neglecting their oral health care. Finally, the treatment of these oral complications must be adapted to the systemic condition and special needs of these individuals, in order not to exacerbate or deteriorate their general health. Guidelines for the treatment of dental complications in this population who require special care are unclear and even unavailable in many aspects. Hence this review was undertaken to provide a basis for clinical care by investigating and analysing the existing evidence in the literature for the treatment of dental complications in people with sickle cell disease. This is an update of a previously published review.ObjectivesTo assess methods of treating dental complications in people with sickle cell disease.Search MethodsWe searched the Cochrane Cystic Fibrosis and Genetic Disorders Review Group's Haemoglobinopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. Date of last search: 01 August 2019. Additionally, we searched nine online databases (PubMed, Google Scholar, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Literature in the Health Sciences in Latin America and the Caribbean database, African Index Medicus, Index Medicus for South East Asia Region, Index Medicus for the Eastern Mediterranean Region, Indexing of Indian Medical Journals). We also searched the reference lists of relevant articles and reviews and contacted haematologists, experts in fields of dentistry, organizations, pharmaceutical companies and researchers working in this field. Date of last search: 07 November 2019.Selection CriteriaWe searched for published or unpublished randomised controlled studies of treatments for dental complications in people with sickle cell disease.Data Collection And AnalysisTwo review authors intended to independently extract data and assess the risk of bias of the included studies using standard Cochrane methodologies; however, no studies were identified for inclusion in the review.Main ResultsNo randomised controlled studies were identified.Authors' ConclusionsThis Cochrane Review did not identify any randomised controlled studies assessing interventions for the treatment of dental complications in people with sickle cell disease. There is an important need for randomised controlled studies in this area, so as to identify the most effective and safe method for treating dental complications in people with sickle cell disease.Copyright © 2019 The Cochrane Collaboration.
