The aim of this study was to evaluate the efficacy of Twisted File (TF) Adaptive, Reciproc, and ProTaper Universal Retreatment (UR) System instruments for removing root-canal-filling. Sixty single rooted teeth were decoronated, instrumented and obturated. Preoperative CBCT scans were taken and the teeth were retreated with TF Adaptive, Reciproc, ProTaper UR, or hand files (n=15). Then, the teeth were rescanned, and the percentage volume of the residual root-canal-filling material was established. The total time for retreatment was recorded, and the data was statistically analyzed. The statistical ranking of the residual filling material volume was as follows: hand file=TF Adaptive>ProTaper UR=Reciproc. The ProTaper UR and Reciproc systems required shorter periods of time for retreatment. Root canal filling was more efficiently removed by using Reciproc and ProTaper UR instruments than TF Adaptive instruments and hand files. The TF Adaptive system was advantageous over hand files with regard to operating time. © 2016, Japanese Society for Dental Materials and Devices. All rights reserved.

Background: Conventional radiographic techniques being two dimensional, has its restrictions and is confined to limited diagnostic value. However, the incorporation of Cone Beam Computed Tomography (CBCT) gives a three dimensional insight to the tooth morphology and leads to better evaluation and treatment management. Aim: The aim of this study was to evaluate and assess the root canal morphology of mandibular pre-molars in South Indian Population using CBCT radiographic technique. Materials and Methods: One thousand and eighty six and Eight hundred and fourteen fully erupted mandibular first and second premolars respectively were scanned using CBCT to evaluate the canal morphology according to Vertucci and Gulabiwala's classification. Results: The most common configuration in mandibular first and second premolars was Vertucci's Type I(83.81% and 93.48% respectively) followed by Type V (11.97% and 3.5% respectively). Conclusion: South Indian Population presented Type IV ertucci's canal morphology as the most common in mandibular first and second pre-molars followed by Type V. CBCT scanning poses a greater advantage in assessing the complexity of root canal morphology and planning an appropriate endodontic treatment for the same.

Huntington's disease and neuroacanthocytosis may present similar clinical and MRI features. It is important to differentiate these findings since treatment and prognosis vary vastly between them. The aim of this article is to familiarize radiologists with the differentiating features of Huntington's disease and various diseases comprising neuroacanthocytosis. A 40-year-old Indian man with extrapyramidal symptoms was referred for MRI. The clinical diagnosis was Huntington's disease, but there were a few atypical clinical features such as a history of biting the tongue, tics, marked hyporeflexia and lower limb muscle wasting. MR showed atrophy of the caudate nucleus and putamen with iron deposition in the basal ganglia, which can be seen in Huntington's disease and in neuroacanthocytosis. An increased blood acanthocyte level was subsequently confirmed. Further work-up revealed increased serum creatine phosphokinase levels, normal serum lipoprotein levels and depressed K cell antigen activity on serological studies, confirming the diagnosis of McLeod syndrome. McLeod syndrome is one of the distinct phenotypes of neuroacanthocytosis. Neuroacanthocytosis is a group of disorders with increased serum acanthocyte counts and neurological involvement. Various causes of neuroacanthocytosis are discussed. It is important to consider the possibility of neuroacanthocytosis when features typical of Huntington's disease are encountered on imaging.

Intakes of micronutrient-rich foods are low among Indian women of reproductive age. We investigated whether consumption of a food-based micronutrient-rich snack increased markers of blood micronutrient concentrations when compared with a control snack. Non-pregnant women (n 222) aged 14-35 years living in a Mumbai slum were randomised to receive a treatment snack (containing green leafy vegetables, dried fruit and whole milk powder), or a control snack containing foods of low micronutrient content such as wheat flour, potato and tapioca. The snacks were consumed under observation 6 d per week for 12 weeks, compliance was recorded, and blood was collected at 0 and 12 weeks. Food-frequency data were collected at both time points. Compliance (defined as the proportion of women who consumed ≥ 3 snacks/week) was >85% in both groups. We assessed the effects of group allocation on 12-week nutrient concentrations using ANCOVA models with respective 0-week concentrations, BMI, compliance, standard of living, fruit and green leafy vegetable consumption and use of synthetic nutrients as covariates. The treatment snack significantly increased β-carotene concentrations (treatment effect: 47·1 nmol/l, 95% CI 6·5, 87·7). There was no effect of group allocation on concentrations of ferritin, retinol, ascorbate, folate or vitamin B12. The present study shows that locally sourced foods can be made into acceptable snacks that may increase serum β-carotene concentrations among women of reproductive age. However, no increase in circulating concentrations of the other nutrients measured was observed. © The Authors 2015.

Background: Acne scars occur consequent to abnormal wound healing following sebaceous follicular inflammation in acne. Various types of acne scars are icepick, rolling, boxcar, hypertrophic, and keloidal. Different modalities of treatment include subcision, dermaroller, cryoroller, punch excision, chemical peeling, and lasers. Objectives: To compare the efficacy of combined subcision and dermaroller vs. combined subcision and cryoroller in acne scar treatment. Methods: Thirty patients (19 males and 11 females) with grade 2, 3, and 4 postacne scarring (Goodman and Baron qualitative grading system) were enrolled in the study. Three sittings each at 1-month interval were carried out of subcision under nerve block on the entire face followed by derma roller (2.5 mm) and cryoroller on one half of the face. Standardized digital photography was performed preprocedure and at 6 months. Grading of acne scar photographs using the Goodman and Baron qualitative and quantitative grading scale was carried out by a blinded observer pre- and postprocedure at 6 months. Patients' own evaluation based on patient scar severity perception scale of 1-10 was also taken into account. Results: Assessment using the quantitative grading scale showed a 57% improvement using combined subcision and cryoroller against 40% improvement with combined subcision and dermaroller. Average improvement perceived by the subjects was 61% with combined subcision and cryoroller against 45% with combined subcision and dermaroller. The data were analyzed using Wilcoxon signed rank test and found statistically significant. Postinflammatory hyperpigmentation on the cryoroller side and erythema, edema, and hematoma formation due to subcision was transient. Conclusion: Combined subcision and cryoroller is more effective than combined subcision and dermaroller for treatment of acne scars. © 2014 Wiley Periodicals, Inc.
