Expression of β-catenin in oral leukoplakia and oral submucous fibrosis: An immunohistochemical study.

Background: Oral potentially malignant disorders have increased propensity to turn malignant than its apparently normal counterparts. Histopathological examination, although gold standard, needs adjunct technique to give accurate diagnosis. Immunohistochemistry has proved to be a promising adjunct to aid in the diagnosis so far.

Formulation of thermoreversible gel of cranberry juice concentrate: Evaluation, biocompatibility studies and its antimicrobial activity against periodontal pathogens.

The present work aims to investigate the efficacy of thermoreversible gel of cranberry juice concentrate (CJC) as local drug delivery for the treatment of periodontitis. CJC was initially tested for its antimicrobial activities like MIC, MBC, antiadhesion, antibiofilm and time kill assay against the panel of organisms (S. mutans (SM), E.

Disinfection of gutta-percha cones using three reagents and their residual effects.

Aims And Objectives: The purpose of this study was to compare the efficacy of 5.25% sodium hypochlorite, 2% chlorehexidine and MTAD in disinfecting gutta-percha cones and to analyze the surface topography of gutta-percha cones after the rapid chemical disinfection procedure.

Materials And Methods: Gutta-percha cones were immersed in suspensions of Enterococcus faecalis and Staphylococcus aureus separately.

Evaluation of smear layer removal from ultrasonically prepared retrocavities by three agents.

Objectives: To evaluate the efficacy of 35% orthophosphoric acid, 24% ethylenediaminetetraacetic acid (EDTA) and 10% citric acid in the removal of smear layer from retrocavities prepared with ultrasonic retro-tips using scanning electron microscopy.

Materials And Methods: Root canals of fifty single-rooted teeth were cleaned, shaped, and obturated with gutta-percha and AH plus sealer. The apical 3 mm of each root was sectioned with a diamond disc and retrograde cavities were prepared with Kis # 1 ultrasonic retro-tips to a depth of 3 mm.

Lead exposure and its relation to dental caries in children.

Unlabelled: Environmental pollution is a significant health hazard and is mainly caused by commercialization. The etiology of dental caries is multifactorial and one such factor is exposure to trace element such as lead.

Aim: Hence, the present study was carried out to find out the correlation between the levels of lead in the enamel, saliva and dental caries in children.

Estimation and comparison of dental, skeletal and chronologic age in Bangalore south school going children.

Objective: Precise evaluation of the developmental stages of a child is an integral part of both diagnosis and treatment planning of pediatric patients and also essential in forensic medicine and dentistry. As human growth shows considerable variation in chronological age, physiological maturity is preferred over chronological age in the estimation of person's exact age.

Materials And Methods: Two hundred and fifty children consisting of 124 girls and 126 boys were selected randomly from the age group of 6-15 years.

Torus palatinus in an infant: a case report.

The most significant exostoses of the human jaws are the torus palatinus and torus mandibularis. Torus palatinus has long been reported by various anthropological and anatomical studies. Even if it has no functional importance, it could interfere with oral functions.

Influence of restorative technique, Bevelling and aging on composite bonding to sectioned incisal edges: A comparative in vitro study.

Aim: To evaluate the effect of direct and indirect technique, bevel placement, and aging on the fracture resistance of composite restorations bonded to sectioned incisal edges.

Materials And Methods: Incisal thirds of 80 human maxillary incisors were sectioned. Four treatment groups of 20 teeth each were formed as follows: Direct composite with bevel and without bevel (Adper single bond 2/Filtek Z350); indirect composite with bevel and without bevel (prepolymerized Filtek Z350 cemented with Adper single bond 2/Relay × ARC).
