Aim: The aim of the study was to evaluate and compare the depth of penetration of adhesive resin in resin-modified glass ionomer cement (RMGIC) after different surface pretreatment methods using a confocal laser scanning microscope (CLSM).
Methods: Class I cavity preparation was done in 45 freshly extracted premolars and divided into three groups, according to the surface pretreatment of RMGIC which was placed in a thickness of 1 mm in the cavity. In the control group, no pretreatment was done, and other two groups were pretreated with acid etching and air abrasion (AA).
Facial traumatic injuries are quite common, resulting in the fracture and displacement of tooth and/or bone fragments. Loss of tooth structure may have lifetime consequences for the patient. Horizontal root fractures (HRFs) may occur in the maxillary anterior teeth at different locations, showing varied patterns of healing.

Aim: To evaluate and compare flexural fracture resistance of mandibular premolars after instrumentation with ProTaperUniversal, ProTaper Next, OneShape, and WaveOne endodontic file systems.
Methods: Seventy-five mandibular premolar teeth with single straight canals were divided into five different groups (n = 15): Group A: Control, Group B: ProTaper Universal (PTU), Group C: ProTaper Next (PTN), Group D: OneShape, Group E: WaveOne.
Aim: This study aims to evaluate and compare the sealing ability of Biodentineā¢ and mineral trioxide aggregate (MTA) plus on root end cavities treated with 17% ethylene diamine tetraacetic acid (EDTA), 0.2% Chitosan and 1% Phytic acid using Confocal Laser Scanning Microscope (CLSM)-An study.
Materials And Methods: Sixty extracted single rooted teeth were instrumented and obturated with gutta-percha.
