Does the use of a 3-mm extended tray during an at-home bleaching treatment increase gingival irritation? A randomized clinical trial.

Statement Of Problem: Gingival irritation is a common side effect of at-home bleaching, but how the design of the bleaching tray affects its occurrence is unclear.

Purpose: The purpose of this randomized clinical trial was to determine whether a direct relationship is present between the design of bleaching trays and the risk of gingival irritation during at-home bleaching treatments.

Material And Methods: This clinical trial was registered at ClinicalTrials.

New Technique for Wedge Selection in Direct Class II Restorations: A Pilot Study.

Performing an appropriate Class II direct restoration is a great challenge. The correct selection of the matrix system and the elements used for its stabilization will have a great impact on the result. The aim of this study is to show a new digital method for a predictable selection of the wedge and compare it with the conventional method.

Vertical preparation: a new technique for analogical and digital impressions.

The BOPT technique (Biologically Oriented Preparation Technique) was proposed by Loi et al. (1) and has become a popular form of vertical preparation for complete crowns with promising results. In this procedure, the clinician can operate on the gingival tissue during preparation and modify its structure in thickness and height by adding modifications on the provisional restoration.

Conservative management of dens in dente.

Dens Invaginatus (DI) or dens in dente is an uncommon anomaly which mostly affects permanent lateral incisors, and it is very rare in molars. This article presents the conservative endodontic management of four different cases of DI and a discussion of the endodontic literature for this malformation. Three upper lateral incisors Type II, IIIa and IIIb, and an upper first molar Type II are shown.
