A Spectrophotometric comparative evaluation of the sealing ability of various perforation repair materials with a novel eggshell modified GIC.

Objectives: The objective of this study was to evaluate and compare the sealing ability of mineral trioxide aggregate (MTA), Biodentine, glass ionomer cement, and glass ionomer cement modified with Chicken Eggshell Powder when used as furcation perforation repair material.

Materials And Methods: In the present study, 80 human lower first molars were used. Collected teeth had no caries or restoration, and none had fused roots.

Comparative Evaluation of Antibacterial Efficacy of Silver and Cadmium Nanoparticles and Calcium Hydroxide against Biofilm.

Aim: The purpose of this study was to evaluate and compare the antibacterial efficacy of calcium hydroxide medicament, silver (AgNPs) and cadmium nanoparticles (CdSNPs) as medicament against the biofilms of on dentin sections. is commonly detected in asymptomatic and persistent endodontic infections.

Methods: Twenty standard size dentin sections were prepared.

Radiographic evaluation of root canal curvature in mesiobuccal canals of mandibular molars by different methods and its correlation with canal access angle in curved canals: An study.

Aims: The aim of this study is to compare three different methods of measuring root canal curvature and its correlation with canal access angle (CAA) in curved mesiobuccal canals of permanent mandibular first molars.

Materials And Methods: Sixty human mandibular first molars were used in this study. Standardized access cavities were prepared.

Effect of Different Cavity Disinfectants on Marginal Sealing Ability of a Seventh-generation Dentin Bonding Agent: An Study.

Aim: To determine the effect of three different cavity disinfectants (2% chlorhexidine gluconate, 2.5% sodium hypochlorite, and 2% iodine solution) on microleakage in a seventh-generation dentin-bonding system.

Materials And Methods: Class V cavity was prepared on 50 extracted molars ( = 50).

Efficacy of botulinum toxin in treating myofascial pain and occlusal force characteristics of masticatory muscles in bruxism.

Aim And Objective: The present study was conducted in patients with bruxism to evaluate the effect of botulinum toxin type A (BTX-A) (Botox, Allergan, Inc., Irvine, CA, USA) in the treatment of myofascial pain and the occlusal force characteristics of masticatory muscles.

Materials And Methods: Twenty-four diagnosed with bruxism were randomly divided into three groups (n = 8) and treated by bilateral intramuscular injection of BTX-A and placebo-treated with saline placebo injections and control group where no injections were given.
