The development of new orally administered anticoagulants, such as dabigatran, rivaroxaban, and apixaban, in the past few years has focused on avoiding some of the drawbacks associated with warfarin. This work aims to illustrate the main features of the most commonly used new oral anticoagulants, reviewing the current literature on the management of patients taking these drugs and needing oral and implant surgery, and discussing the currently proposed related guidelines.

Miller's is the most commonly used classification of gingival tissue recessions, defined as the displacement of the soft tissue margin apical to the cemento-enamel junction. However, data on the reliability of this classification are missing so far, although reliability, which reflects the consistency of repeated measurements, is regarded as a prerequisite for judging the utility of a classification. The aim of the present study was to evaluate inter- and intra-observer agreement on Miller's classification of gingival tissue recessions. ⋯ Further, gingival phenotype (thin-high scalloping) significantly correlated with tooth shape (long-narrow) (ρ = 0.662, p < 0.001). Miller's classification of gingival tissue recessions was evaluated by four examiners using 200 clinical photographs and yielded substantial to almost perfect agreement, with higher agreement for anterior teeth. Although limited to photographic assessment, the present study offers the so far missing proof on the sufficient inter- and intra-observer agreement of this classification.
