Effect of rosmarinic acid on microtensile bond strength of 1-step self-etch adhesive on artificial caries-affected dentine with or without NaOCl treatment: An in-vitro study.

This study investigated the effect of rosmarinic acid (RA) on the immediate microtensile bond strength (µTBS) of 1-step self-etch adhesive to artificial caries-affected dentine (CAD), with or without NaOCl treatment. Dentine surfaces of 60 premolars were subjected to pH-cycling for artificial caries induction. Samples were randomly categorized into: NaOClRA group treated with 6% NaOCl and RA, RA group treated with RA solution, NaOCl group treated with 6% NaOCl, and untreated control group.

Effect of deep margin elevation on fracture resistance of premolars restored with ceramic onlay: comparative study.

Background: This comparative study aimed to compare the influence of two levels of deep margin elevation (2 and 3 mm) with either bulk-fill flowable composite or short fiber-reinforced flowable composite on the fracture resistance of maxillary first premolars restored with ceramic onlays.

Material And Methods: Fifty sound-extracted maxillary first premolar teeth were selected to prepare mesio-occluso-distal cavities with standardized dimensions. The cervical margins were extended 2 mm below the cemento-enamel junction on both mesial and distal sides.

Comparison of different bioglass applications on root caries - A laboratory-based study.

The aim of this study was to assess the effect of bioglass with different concentrations on root caries. Ninety freshly-extracted teeth with root caries were randomly assigned to a single-use prophylaxis paste containing 15 % bioglass for 30 s with 1,450 ppmF toothpaste (15 % bioglass, n = 30), 1,450 ppmF toothpaste with 5 % bioglass (5 % bioglass, n = 30), and toothpaste containing 1,450 ppmF (Control, n = 30). Each sample received a standard brushing procedure for 10 s twice a day using the toothpastes.

Reversal of Root Caries with Casein Phosphopeptide-Amorphous Calcium Phosphate and Fluoride Varnish in Xerostomia.

Different formulas of topical fluoride have been used to manage root carious lesions. This clinical trial aimed to investigate the efficacy of a dental varnish containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and fluoride compared with fluoride alone in reversing/arresting root caries in xerostomic patients over 1 year. A total of 80 patients (age range 45-92 years) with primary root caries (n = 184 root carious lesions) and unstimulated salivary flow rate of <0.

A comparative evaluation of ion release characteristics of three different dental varnishes containing fluoride either with CPP-ACP or bioactive glass.

Objective: To compare ion release characteristics of three different dental varnishes either containing CPP-ACP and fluoride (CPP-ACPF, MI Varnish GC, Japan), bioactive glass and fluoride (BGAF, Dentsply Sirona USA) or fluoride alone (NUPRO White, Dentsply Sirona USA) using fluoride-Ion Selective Electrode (F-ISE), Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), F and P Magic Angle Spinning-Nuclear Magnetic Resonance (MAS-NMR).

Methods: A thin layer (0.0674±0.
