Effectiveness of Lidocaine versus Lidocaine with Magnesium Sulphate During Inferior Alveolar Nerve Block in Patients with Symptomatic Irreversible Pulpitis: A Randomised Double-Blinded Clinical Trial.

Objective: This study aimed to compare the effectiveness of lidocaine with magnesium sulphate in patients undergoing root canal treatment following irreversible pulpitis.

Methods: A total of 86 patients were randomised to receive 1.8 ml of 2% lidocaine replaced with 0.

Biomechanical Properties of Maxillary Second Molar with Different Endodontic Cavity Designs - A Finite Element Analysis.

Aim: To evaluate the biomechanical properties of maxillary second molars with three different cavity designs - Traditional, Conservative, and Extended - endodontic cavities using the finite element analysis method.

Materials And Methods: Three finite element models of a maxillary second molar with three different types of endodontic cavities were designed and restored. Each model was subjected to three different force loads directed at the occlusal surface.

Evaluation of Reliability and Validity of Occlusal Caries Detection by Direct Visual, Indirect Visual and Fluorescence Camera Using ICDAS II (Codes 0, 1, and 2): An Study.

Introduction: Early detection of carious lesions paves the way for the preservation of tooth structures by remineralization strategies. Visual examination using international caries detection and assessment system (ICDAS) II has been validated with the gold standard of histological classification. A fluorescence camera is yet another diagnostic aid for the early detection of carious lesions based on the autofluorescence of the enamel and dentin.

Antibacterial Effect and Tensile Bond Strength of Self-etching Adhesive Resins with and without Methacryloyloxydodecylpyridinium Bromide: An Study.

The aim of the present study was to compare the antibacterial activity of a self-etching primer containing antibacterial monomer methacryloyloxydodecylpyridinium bromide (MDPB) (Clearfil protect bond) with a conventional self-etching primer without MDPB (Clearfil SE bond) against and the effect of incorporation of MDPB on the tensile bond strength of the experimental self-etching primer (Clearfil protect bond). The antibacterial activity of the self-etching primers was assessed using agar disk diffusion method and the diameters of the zones of inhibition were measured and ranked. For tensile bond strength testing, 20 noncarious human molars were selected and randomly divided into two groups comprising 10 teeth in each group.

Periapical actinomycosis.

Actinomycosis is a rare chronic infection caused by species of Actinomyces and characterised by abscess formation, tissue fibrosis, suppurative lesions and fistulas with purulent discharge containing sulphur granules. Owing to its multiform manners of presentation and non-specificity from its clinical features, it has been considered as a challenging diagnosis. Periapical actinomycosis is one of the rarest forms of actinomycosis occurring in the maxillofacial region.
