Effect of preheating nano-hybrid and bulk-fill composites with warm airstream on their microtensile bond strength to dentin.

Aims: This study assessed the effect of preheating nano-hybrid and bulk-fill composites with warm airstream on their microtensile bond strength (MTBS) to dentin.

Materials And Methods: In this in vitro study, dentin was exposed in 42 extracted premolars that were assigned to two groups ( = 21) for bonding to EverX Posterior bulk-fill and Grandio nano-hybrid posterior composite. Each group was subdivided into three subgroups for preheating of composite to 50°C by a commercial composite warmer (Subgroup 1), a warm airstream by a hair dryer for 10 s (Subgroup 2), and no heating (room temperature; Subgroup 3).

Conservative and cost-effective rehabilitation of a deep bite patient with worn dentition: A case report of the Dahl technique approach.

The reformation of teeth with severe wear is a real challenge for clinicians. Through a clinical case study, this case illustrates a minimally invasive approach using the Dahl technique and bonded restorations for the treatment of a worn dentition with a loss of vertical dimension of occlusion and restoring ideal aesthetics.

Analyzing the Causes and Frequency of Early Dental Implant Failure among Iranians: An Epidemiological Study.

Aim: The rate of early dental implant failure (DIF) has increased in recent years, though the risk factors associated with this primary failure remain unclear. This study aimed to determine the rate of early implant failure and identify contributing factors. It was conducted from March 2018 to 2020 in Mashhad, Iran.
