fa Failure of incompletely excavated teeth—A systematic review پریودنتولوژی Periodontology پژوهشي Research <p> <strong>Objectives</strong></p><p>  When treating deep caries, one- and two-step incomplete caries removal reduce the risk of pulpal exposure. However, it is currently unclear if incompletely excavated teeth fail due to pulpal or rather non-pulpal complications. The present study systematically analysed how incompletely excavated teeth fail, and if certain tooth- or treatment-related factors may influence risk of failure. </p><p> <strong>Data</strong></p><p>  Clinical studies investigating clinical or radiologic failure after incomplete excavation of deep caries (depth >1/2 dentine thickness) were evaluated. Weighted annual failure rates (AFRs) were used to analyse frequency and mode of failures. Sub-analyses compared risk of failure in different groups of possible influencing factors. </p><p> <strong>Sources</strong></p><p>  Electronic databases were screened and studies cross-referenced. Language was restricted to English and German. Grey literature was not evaluated. </p><p> <strong>Results</strong></p><p>  19 studies with a median (Q25/75) follow-up of 24 (12/48) months were included. AFR was 3.8 (1.4/4.4)%. Eleven studies reported pulpal complications being the major reason for failure, and only 2 studies found more non-pulpal than pulpal failures. Sub-analyses found significantly lower risk of failure for teeth after one- compared with two-step excavation (Odds ratio [95% CI]=0.21 [0.08, 0.55]) and teeth with single- compared with multi-surface cavities (0.33 [0.16, 0.67]). Risk of bias differed widely between studies, and evidence levels were graded as very low. </p><p> <strong>Conclusions</strong></p><p>  After incomplete removal of deep caries, pulpal failure was more common. One- compared with two-step excavation reduces risk of failure, and factors like number of restored surfaces seem to but influence failure, but limited evidence permits drawing definitive conclusions. </p><p> <strong>Clinical Significance</strong></p><p>  Growing evidence indicates that one-step incomplete excavation seems suitable to treat deep caries lesions, and might have advantages compared to two-step incomplete or complete caries removal. However, it is too early to recommend certain clinical strategies. </p><hr><p></p><p> <strong>Source: </strong>Journal of Dentistry</p><p><a href="http://www.jodjournal.com/article/S0300-5712(13)00127-9/abstract"><font color="#0000ff"> Full Text</font></a></p><p>  </p> Caries removal, Incomplete excavation, Partial excavation, Failure, Survival 0 0 http://idai.ir/browse.php?a_code=A-10-32-2167&slc_lang=fa&sid=1 F.
