Natural Polyphenols From Moringa and Centella Extracts as Collagen Cross-Linkers and Matrix Metalloproteinase (MMP) Inhibitors in Dentin Preservation: An In Vitro Study.

Background In adhesive dentistry, creating a long-lasting bond between resin composite and dentin is crucial. The durability of this bond dramatically depends on the structural integrity of collagen fibrils present in the hybrid layer. However, matrix metalloproteinases (MMPs) can degrade collagen fibrils, compromising the bond's longevity.

Lost and found! Tooth fragment reattachment after 8 Mo of trauma.

Thorough clinical and radiographic evaluation of patient following orofacial trauma is indispensable for a successful outcome, and when the tooth fragment is available in a good condition, then fragment reattachment is the best choice of treatment.

Evaluation of Levels of Proinflammatory Chemokines MIP-1α and MIP-1β in Gingival Crevicular Fluid of Primary, Mixed and Permanent Dentition.

Aim: This study aims to find out the proinflammatory chemokines macrophage inflammatory protein (MIP)-1α and MIP-1β levels in gingival crevicular fluid (GCF) of primary, mixed, and permanent dentitions.

Materials And Methods: GCF of 160 individuals (4-15 years of age) was collected by the extracrevicular method. They were categorized into four groups (40 per each group).

Esthetic Clasp Cast Partial Denture.

Denture esthetics as defined by Glossary of prosthodontics terms the effect produced by a dental prosthesis that affects the beauty and attractiveness of the person. [1] Removable partial dentures (RPDs) are the widely accepted and treatment of choice for most cases as it is both effective and affordable. Partially edentulous treatment planning includes both esthetics and masticatory function.

Novel metabolites from Trichoderma atroviride against human prostate cancer cells and their inhibitory effect on Helicobacter pylori and Shigella toxin producing Escherichia coli.

The present study aimed to purify and identify the metabolites from T. atroviride using high-performance liquid chromatography (HPLC) and H and C nuclear magnetic resonance spectrometer (NMR) followed by analyzing their toxicological, antibacterial and anticancer properties. This work identified two metabolites - TM1 and TM2.

Effect of addition of lycopene to calcium hydroxide and chlorhexidine as intracanal medicament on fracture resistance of radicular dentin at two different time intervals: An in vitro study.

Background: Long-term use of intracanal medicaments such as calcium hydroxide (CH) reduces the fracture resistance of dentin. The present study was undertaken to evaluate the fracture resistance of radicular dentin on long-term use of CH, chlorhexidine (CHX) with lycopene (LP).

Aim: To compare the fracture resistance of radicular dentin when intracanal medicaments such as CH, CHX with LP were used for 1-week and 1-month time interval.

Effect of saliva and blood contamination on the bond strength of self-etching adhesive system- An in vitro study.

Aim: The aims of this study were to determine the effect of saliva and blood contamination on the shear bond strength of self-etching adhesive to enamel and dentin; and, to compare the difference in bond strength due to contamination beforeand after application of the self-etch adhesive.

Materials And Methods: 40 human mandibular molars were wet ground on both buccal and lingual surfaces to prepare flat superficial enamel and dentin surfaces. They were randomly divided into two groups (n = 40) based on the substrate (enamel and dentin).

Comparative evaluation of tensile bond strengths of total-etch adhesives and self-etch adhesives with single and multiple consecutive applications: An in vitro study.

Aim: This study evaluates the effect of single and multiple consecutive applications of adhesives on the tensile bond strength. The currently available adhesives follow either the total-etch or the self-etch concept. However, in both techniques the uniformity and thickness of the adhesive layer plays a significant role in the development of a good bond.
