To evaluate the influence of smoking on survival rate of endosseous implant. The literatures published before the year 2012 involving influence of smoking on survival rate of endosseous implant were searched in PubMed,Embase and Cochrane databases. Data from the literatures conforming to the inclusion criteria and exclusive criteria were selected and a meta-analysis was carried out. Sixteen literatures conforming to the inclusion criteria and exclusive criteria were screened out, which were prospective or retrospective cohort studies. Meta analysis using random effects model showed smoking patients had higher risk to lose endosseous implants than non-smoking patients (synthesized OR 2.24,95% CI 1.66-3.01,P<0.01), which implied the survival rate of endosseous implant in smoking patients was lower than in non-smoking patients. Heterogeneity source was not figured out by meta regression and subgroup analysis. When sensitivity analysis was done by using fixed and random effects model alternatively or excluding articles in which the distribution of implant surface characteristics were uneven between smoking and non-smoking group, result was not changed obviously. The existing limited evidences show that smoking is harmful to the sur...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
