Effects of Various Solutions on Color Stability and Surface Hardness of Nanohybrid Dental Composite Under Simulated Oral Conditions.

Aim: This study evaluated effects of various solutions on color stability and surface hardness of a nanohybrid dental composite in simulated oral environments.

Materials And Methods: Sixty-four composite disks were fabricated and randomly allocated into eight groups ( = 8 per group): Artificial saliva (AS), Biotene (B), passion fruit juice (PFJ), orange juice (OJ), Sprite (S), Coca-Cola (CO), apple cider vinegar (ACV), and cranberry juice (CJ). Specimens were immersed in respective solutions at 37°C for 28 days.

4-Year Pulp Survival in a Randomized Trial on Direct Pulp Capping.

Introduction: This study aimed to assess pulp survival in a randomized trial on pulp lavage in adult nonpainful posterior teeth with carious pulp exposure. The treatment included complete caries excavation, direct pulp capping with mineral trioxide aggregate, and immediate restoration with composite resin.

Methods: Fluid was collected from the pulp wound to assess matrix metalloproteinase-9 (MMP-9) and total protein values.

comparative study of antimicrobial efficacy of endodontic sealers against common pathogens in the dental pulp.

Overview: Different types of bacterial species, (), (), and (), cause pulpal and periradicular diseases. Hence, the antibacterial efficacy of endodontic sealers is of utmost importance from a clinical point of view.

Aim: The main objective of the study is to test the antibacterial efficacy of endodontic sealers against endo microflora belonging to , , and species.

Sodium Hypochlorite Reduces Postoperative Discomfort and Painful Early Failure after Carious Exposure and Direct Pulp Capping-Initial Findings of a Randomized Controlled Trial.

In this randomized controlled single-center clinical trial on 96 adult patients with parallel experimental groups ( = 48), the effects of washing a dentin/pulp wound in non-symptomatic teeth with extremely deep caries and pulpal exposure were compared between a 2.5% sodium hypochlorite (NaOCl) solution and a chemically-inert physiological saline control solution. After the allocated wound lavage, the pulps were capped with a mineral trioxide aggregate, covered by a glass-ionomer/resin liner, and the teeth were immediately restored with a resin-bonded-composite.

Evaluating the Effect of Different Conditioning Agents on the Shear Bond Strength of Resin-Modified Glass Ionomers.

Aim Of The Study: This study aims to evaluate the effects three different conditioning agents on the shear bond strength of resin-modified glass ionomers to human dentin.

Materials And Methods: One hundred and twenty recently extracted, caries-free premolars and molars will be cleaned of debris and disinfected in a 0.5% solution of sodium hypochlorite and sterile water for 30 min.
