Multiple gingival recessions associated with non-carious cervical lesions treated by partial restoration and modified coronally advanced flap with either connective tissue graft or xenogeneic acellular dermal matrix: A randomized clinical trial.

Background: This study aimed to compare a connective tissue graft (CTG) to a (porcine) xenogeneic acellular dermal matrix (XDM), both associated with modified coronally advanced flap (MCAF) and partial resin composite restoration to treat multiple combined defects (CDs).

Methods: Seventy-eight defects in 38 patients presenting multiple combined defects, that is, gingival recession associated with non-carious cervical lesions, were treated by partial resin composite restoration (apical margin up to 1 mm of the estimated cement-enamel junction) and MCAF along with CTG or XDM. After 6 months, the groups were compared with regard to clinical, patient-centered, and esthetic outcomes.

Impact of simulated toothbrushing on surface properties of chairside CAD-CAM materials: An in vitro study.

Statement Of Problem: Chairside computer-aided design and computer-aided manufacturing (CAD-CAM) materials that do not require any firing steps are a promising option to expedite restoration production; however, little information is available to determine the most suitable material for each clinical situation.

Purpose: The purpose of this in vitro study was to evaluate the effect of simulated toothbrushing on surface gloss, roughness, and wear of chairside CAD-CAM materials.

Material And Methods: Disk-shaped specimens (n=15) were prepared of the following materials: ENA-VITA Enamic; LAV-Lava Ultimate; EMP-IPS Empress CAD; CER-Cerasmart; GRA-Grandio blocs.
