Aims: The aim of the study is to evaluate the efficacy of neem and turmeric as storage media in maintaining periodontal ligament (PDL) cell viability.
Materials And Methods: Ninety premolar extracted teeth were randomly selected and divided into three groups, namely milk as a control group and neem and turmeric as experimental groups. The teeth were placed in one of the three storage media for 30 min.

Material And Method: Nickel ion release was evaluated after subjecting the brackets to the simulated artificial oral environment. In this study, 90 stainless steel brackets of 3M Unitek Company were tested by immersing them in artificial saliva of pH 4.
Introduction: Pulpotomy technique is most widely accepted clinical procedure for treating primary teeth with coronal pulp inflammation caused by caries with no involvement of the radicular pulp.

Awareness and prevention of patient gag reflex among pedodontists in India: A web-based survey.
J Indian Soc Pedod Prev Dent
November 2017
Aim: The aim of this study is to devise a reliable and valid web-based survey to predict the awareness level and prevention of patient's gag reflex among Indian pedodontists.
Materials And Methods: An 11-question predictive gagging survey was created, refined, and tested on 377 pedodontists. The questions focused on age group, common procedure associated with gag reflex and the most common technique adapted by dentists in their clinics to prevent gag.
Introduction: The cariostatic property of glass ionomer cement (GIC) stems from its ability to release fluoride into the oral environment. Recently, zirconia reinforced GIC has been launched which promises the protective benefits of glass ionomer while completely eliminating the hazard of mercury.
Aim: To evaluate invitro antibacterial activity and fluoride release from two conventional glass ionomer cements (GC II and GC IX), compomer (Compoglass) and a zirconia reinforced glass ionomer cement (Zirconomer).
Objectives: The study was aimed to evaluate the pharyngeal airway linear measurements of untreated skeletal class II subjects with normal facial vertical pattern in prognathic maxilla with orthognathic mandible and orthognathic maxilla with retrognathic mandible.
Materials And Method: the sample comprised of lateral Cephalograms of two groups (30 each) of class II malocclusion variants. Group 1 comprised of class II malocclusion with prognathic maxilla and orthognathic mandible, whereas group 2 comprised of class II malocclusion with orthognathic maxilla and retrognathic mandible.
Purpose: The purpose of vitro study was to assessment of the bacterial contamination on daily twice-used toothbrushes in different conditions after 1-month and 3 months.
Materials And Methods: Forty children aged between 6 and 12 years were selected for this study. Toothbrushes and toothpaste were distributed among those children.
Objective: This article aims to analyze the difference in stresses generated in the bracket-cement-tooth system by means of a peel load in single and double-mesh bracket bases using a three-dimensional finite element computer model.
Material And Methods: A three-dimensional finite element model of the bracket-cement-tooth system was constructed and consisted of 40,536 bonds and 49,201 finite elements using a commercial mesh generating programmer (ANSYS 7.0).
Aim: The aim of this study was to relate the salivary electrolyte levels with dental caries in children with Down syndrome and to compare salivary electrolyte levels and dental caries of these children with their siblings.
Materials And Methods: Study population consisted of 30 Down syndrome children (study group) and their 30 healthy siblings (control group). Caries status was determined by dental caries indices in deciduous and permanent dentitions.
Evaluation of physio-chemical properties of saliva and comparison of its relation with dental caries.
J Indian Soc Pedod Prev Dent
September 2015
Objective: Objective was to evaluate the relationship between physio-chemical properties of saliva such as flow rate, buffering capacity, pH, Streptococcus mutans in saliva and its relationship with dental caries.
Study Design: Eighty children were evaluated for physio-chemical properties of saliva, out which 40 were caries-active (group 1) and 40 caries-free (control group). Caries status of each child was scored by using DMFS and dfs indices to get a combined DMFS and dfs score.
Background: To assess the prevalence of malocclusion and to determine the different occlusal characteristics in primary dentition of 4 to 6 years old children in India.
Materials And Methods: The target population comprised 4 to 6 years old children attending different nursery, kindergarten and primary schools of Bagalkot city. Stratified cluster random sampling procedure was executed to collect the representative sample.
Aims: The aims of the study were: to assess the prevalence of traumatic injuries to the teeth of 4- to 6-year-old children living in Gulbarga City, India, to determine prevalence of such dental traumatic injuries at the ages of 4, 5, and 6 years and to compare the prevalence of these injuries between male and female children.
Methods: A cross-sectional survey was performed. It consisted of a clinical examination of upper and lower deciduous anterior teeth by one examiner and an interview using a questionnaire with a sample of 1500 children aged 4 to 6 years who attended kindergarten and primary schools in Gulbarga city.
Purpose: To evaluate the efficacy of plaque removal of four different toothbrushes in visually disabled children. Three manual toothbrushes with different bristle designs (Oral-B CrossAction 40-regular, Oral-B ShinyClean 40-soft, Oral-B Advantage 40-soft) were compared with an electric toothbrush with an oscillating rotating head (Colgate Motion).
Materials And Methods: Forty visually impaired children in a professional education center participated in the study and were divided into 4 groups of 10 participants each.
Aim: To analyze the influence of bracket base mesh geometry on the stresses generated in the tooth-cement-bracket continuum by a shear/peel load case and to compare the stress generated by three different loads (masticatory, peel, and twisting) on the bracket mesh base by employing a three-dimensional (3D) finite element computer model.
Methods: A validated 3D finite element model of the bracket-cement-tooth system was constructed consisting of 40,536 nodes and 49,201 finite elements.
Results: An increase in the diameter of the bracket mesh base wire resulted in a decrease in the stress at the enamel and cement.
Purpose: To record, determine and discuss the gender influence on the overall prevalence of occlusal characteristics of primary dentition of 4- to 6-year-old children of Bagalkot City, India.
Materials And Methods: A total of 1000 children (583 boys and 417 girls) 4 to 6 years old were evaluated clinically for primary molars, primary canines, developmental spaces, measurements of overjet and overbite, crowding, anterior or posterior cross bite, midline discrepancies, lateral profile, as well as assessment of the presence of lip incompetency. A stratified cluster random sampling procedure was executed to collect the representative sample.
Aims: To assess the attractiveness of dentofacial midline discrepancies during smiling, and to determine if the ratings were influenced by the gender of the judges.
Methods: Twenty non-dental undergraduate students (10 males, mean age: 33.5 years; 10 females, mean age: 31.
