THE EFFECT OF ACID ETCHING TREATMENT ON SURFACE PROPERTIES OF DENTAL HARD TISSUE

Romanian Journal of Oral Rehabilitation
Our study aims to investigate the acid etching treatment effects applied on dental structures, considering their surface properties. We have used a liquid PA in a concentration of 36.1% wt. (36.1% PA) and a gel PA with 35% wt. (35% PA) active compound as etching agents. These substances were applied to the human teeth for a maximum of 15 seconds.

Diagnostic Accuracy of Dentin Sclerosis by Optical Coherence Tomography and the North Carolina Index in Noncarious Cervical Lesions

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the diagnostic accuracy of optical coherence tomography (OCT) and the North Carolina Index (NCI) for identifying dentin type (sclerotic vs. nonsclerotic) in natural noncarious cervical lesions (NCCLs). Materials and Methods Thirty extracted human premolars with 30 NCCLs (90 regions of interest) were analyzed. Two blinded,

Finite element analysis of primary healing implants with different transmucosal designs

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to assess the response of peri‐implant tissues, both hard and soft, to mechanical stress when using a primary healing implant (PHI) with two different transmucosal profiles: concave (Model A) and divergent (Model B). The investigation also sought to observe bone modeling under post‐extraction conditions.
