Effect of Implant Abutment Acid Etching on the Retention of Crowns Luted with Different Cements: An Comparative Evaluation.

Background: Air abrasion of the implant abutment surface improves the bond strength of luting agents. However, the effect of acid etching and combination of air abrasion and acid etching on the bond strength of various luting agents under masticatory load is yet to be documented.

Purpose: The purpose of this study was to evaluate the effect of implant abutment surface modifications on the tensile bond strength (TBS) of cast metal copings (CMCs) luted with different luting agents, subjected to cyclic fatigue loads.

Effect of Surface Modifications on the Retention of Cement-retained Implant Crowns under Fatigue Loads: An Study.

Background: Masticatory forces cause fatigue to the dental luting agents, adversely affecting the retention of these cement-retained crowns. Sandblasting (SB) and diamond abrading the abutment surface improves the bond strength of luting agents. However, the effect of acid etching (AE) on the implant abutment surface and the effect of other surface modifications under masticatory load are yet to be documented.

A comparative evaluation of microleakage of restorations using silorane-based dental composite and methacrylate-based dental composites in Class II cavities: An study.

Aim: The aim of this study was to evaluate and compare the microleakage of restorations using low shrinkage silorane-based dental composite and methacrylate-based dental composites in Class II cavity at the occlusal and gingival margins.

Materials And Methods: Sixty mandibular molars were collected and divided into three experimental groups and one negative control group. Class II slot cavity was prepared on the mesial surface.

Comparative clinical evaluation of transcutaneous electrical nerve stimulator over conventional local anesthesia in children seeking dental procedures: A clinical study.

Aim: The aim of this study to evaluate the effectiveness of pain control by employing transcutaneous electrical nerve stimulator (TENS) over conventional injectable local anesthesia for children requiring restorative procedures under rubber dam.

Materials And Methods: The study design considered was the split mouth design, in experiment (right) side, dental procedures under rubber dam was performed under TENS and in control (left) side, dental procedures under rubber dam was performed under conventional injectable local anesthetic (LA). The level of comfort and discomfort experienced during TENS and conventional LA was determined using visual analog scale (VAS) and heart rate.
