Evaluation of microtensile bond strength and marginal adaptation of fiber-reinforced composites.

Background: Long-term durability of a restoration relies on the marginal integrity and its ability to withstand the occlusal forces. Fiber-reinforced composites (FRCs) exhibited superior properties in terms of fracture toughness, flexural strength, and wear resistance.

Aim: The aim of this study was to assess and compare marginal adaptation and microtensile bond strength (µTBS) of posterior FRCs comparing with a condensable composite.

Effect of ultrasonic and Er,Cr:YSGG laser-activated irrigation protocol on dual-species root canal biofilm removal: An study.

Aim: The aim of the study was to investigate the disinfecting efficacy of a standardized irrigating solution activated by ultrasonics or laser irradiation on mature dual-species biofilms at different root levels .

Materials And Methods: Conventional access cavity preparations were done on 160 single-rooted mandibular premolar teeth with single canals. Freshly extracted oral microbial strains of , , , and after biochemical confirmation were used to generate two discrete dual-species microbial inoculums.

Influence of access cavity design on root canal instrumentation efficacy in molars - An study.

Background: Several designs of access cavity have been evolved in the recent past with the concept of minimal tooth tissue removal which would improve the root canal treated teeth fracture resistance.

Aim: To investigate the effect of conservative design access cavity during the instrumentation of maxillary molar root canals.

Materials And Methods: Eighty noncarious maxillary molars were assigned to the traditional and conservative access groups ( = 40 each).
