compared to students who were taught behavior management methods by traditional methods only. AZD9291 chemical structure Clinical skill simulation using standardized patient is an effective adjunct to be used along with traditional method of teaching while teaching behavior management and modification skills to dental undergraduate students.

Early childhood caries (ECC) has been regarded as one of the most prevalent chronic diseases in children. Conventional restorative management of ECC is difficult to perform in very young and apprehensive children. Silver diamine fluoride (SDF) can be a useful tool in the management of dental caries by arresting the carious lesion in primary teeth. After SDF treatment, the dentinal staining that is associated with SDF influences the acceptance of this treatment among parents of young children.

This study aimed to evaluate the clinical effectiveness of biannual application of 38% SDF followed by 5% sodium fluoride (NaF) varnish for arresting dental caries in children and its parental acceptance.

Twenty-six children aged 2-5 years with 107 active caries lesions in primary teeth were enrolled. At the baseline examination, status of carious lesions was recorded and scored according to the International Caries Detection and Assessment System II. Lesion activity was assessed by visual inspection and tactile detection. Carious lesions with score 3, 4, 5, and 6 were treated with 38%SDF application, followed by 5% NaF varnish. Children were re-evaluated at 3 weeks, 3 months, 6 months, and 12 months. Parental acceptance of SDF treatment was evaluated.

This study demonstrated that 38% SDF was 92.31% effective in arresting dental caries in primary teeth and was well accepted by parents. Chi-square test was used to assess the significant difference among the arrested lesions which was statistically significant (P < 0.05).

Thirty-eight percent SDF can be effectively used in arresting caries in primary teeth in young and uncooperative children.

Metapex/Vitapex is one of the most commonly used obturating materials in pediatric dental practice in recent times. It is available in a premixed syringe which poses numerous practical difficulties. This study aimed to calculate the root canal volume of maxillary and mandibular canine and second molar using cone-beam computed tomography (CBCT) to determine the quantity/grams of obturation material to obturate a single tooth (mass = density × volume).

This nonrandomized clinical trial is comprised of two parts. The first part involved calculation of average root canal volume using CBCT which was used to calculate the quantity/grams of obturating material. This predetermined quantity was used to obturate primary mandibular second molars and canines, and the quality of obturation was assessed.

Assessment of quality of obturation showed optimum length obturation in 53.33% primary second molars and 66.66% primary canines.

It can be inferred that even with the use of exact predetermined quantity/grams of obturating material, optimum quality obturation could be achieved, thus avoiding wastage, preventing cross contamination, and simultaneously offering good clinical results. Hence, this study opens further gateways to device ampules containing predetermined mass of obturating material for a single use for obturation of a single primary tooth.

In the last few decades, the availability of synchrotron sources has initiated revolutionary advances in X-ray imaging.

The study aimed to evaluate the incidence of apical transportation after root canal preparation with ProTaper Gold (PTG), Hyflex electro discharge machining (HEDM), Reciproc (RPC), and WaveOne Gold (WOG) using synchrotron radiation-based micro-computed tomographic (SR-μCT) analysis.

Forty mandibular molars were assigned to four experimental groups (n = 10) according to the file system used for the root canal preparation Group 1 PTG (25/0.08), Group 2 HEDM (25/0.08), Group 3 RPC (25/0.08), and Group 4 WOG (25/0.07). The specimens were scanned on SR-μCT system before and after the root canal preparation. Apical transportation was assessed at 1, 2, 3, 4, and 5 mm section.

Two-way analysis of variance and Wilcoxon Mann-Whitney test was used.

No significant difference was found between the groups. Transportation in the mesial direction was of greater magnitude than distal transportation for all the files systems.

SR-μCT can be used as a reliable diagnostic tool for further implications.

Dental caries is one of the most prevalent posteruptive bacterial infections worldwide, characterized by a progressive demineralization process that affects the mineralized dental tissues. Although the decline of dental caries prevalence can be attributed to the widespread use of dentifrices that contain fluoride, yet there is a need for an advanced alternative nonfluoride remineralizing dentifrice. Yet, there is a need for an advanced alternative nonfluoride remineralizing dentifrice.

The aim of this study was to evaluate and compare the remineralizing effect of nonfluoride-based and herbal-based pediatric dentifrice in demineralized primary teeth with an ideal in vitro method of pH cycling and evaluating the values under Polarized Light Microscope (Olympus BX43) using image analysis software (ProgRes, Speed XT core3).

A total of 30 tooth samples were collected and placed in the demineralizing solution for 96 h to produce a demineralized lesion of approximately 100 μm, and then cut longitudinally into in remineralizing the demineralized lesion, while herbal-based dentifrice showed poor efficiency in remineralizing the demineralized lesion.
