Introduction According to the “silica hypothesis” formulated to explain homeopathy, the information of starting materials would be transferred to cells by silica nanoparticles detached from the glassware walls by serial dilution and agitation through epitaxy. We compared the biological activity, electrical current and silicon microparticle content (by means of scanning electron microscopy/energy-dispersive X-ray spectroscopy) of high dilutions (HDs) of arsenic prepared in plastic and glass vials to investigate the role of silica in their biological effects in vitro.
Materials and Methods Co-cultures of macrophages and yeast (Saccharomyces cerevisiae) were treated with different HDs of arsenic prepared in plastic and glass vials. Macrophage morphology, phagocytosis index, nitric oxide (NO), and cytokine production were evaluated.
Results Measurable amounts of silicon microparticles were detected only in the HDs prepared in glass vials, but ultra-centrifugation eliminated them. Specific and non-specific results were observed. Non-specific pro-inflammatory effects were seen in all dilutions prepared in plastic vials, including elevation of pro-inflammatory cytokines, NO and macrophage phagocytic index. Only the 200th centesimal dilution of arsenic produced specific decrease in interleukin-6 production in macrophages, and it was independent of the vial type or the presence of microparticles of silica in the medicine samples. The nature of the vials had an impact on the electric flow in the respective fluids.
Conclusion The non-specific, pro-inflammatory effects might be attributed to organic residuals detached from the vials' plastic walls during manipulation. Instead, specific silica-independent effects of the homeopathic medicine can be attributed to the decrease of interleukin-6 after treatment with the 200th centesimal dilution of arsenic.

Authors: Ahuja Gourav , Marya Jaideep , Sood Poonam 
Published: October 2018

AbstractSalivary gland tumors account for less than 3% of the head and neck tumors. Among various salivary gland tumors, pleomorphic adenoma is most common and accounts for 60- 70% of the benign tumors of salivary glands. However, the involvement of minor salivary glands of buccal mucosa is extremely uncommon and reported to be 4% only. Salivary glands may present with a diverse range of lesions presenting a challenge to even the most experienced clinician. We report two rare cases of pleomorphic adenoma of minor salivary glands of buccal mucosa in a 45 year old female and 70 years old male respectively. It includes clinical features, diagnosis and treatment of the tumor.

Published: October 2018

Abstract
Objectives: This study was undertaken to evaluate the efficiency of two rotary nickel titanium instruments and hand instrumentation in removing gutta-percha and sealer from root canals. Study design: – 63 extracted human single rooted premolars were instrumented with K-files and filled using lateral compaction of gutta-percha (GP) and three different sealers. The teeth were randomly divided into three experimental groups of 21 specimens each. Removal of gutta-percha was performed with R-Endo retreatment files, Mtwo retreatment files and Hedstrom files. Time to reach working length and to eliminate filling material was also recorded. The specimens were sectioned for evaluation of the area of the remaining gutta-percha/sealer under stereomicroscope at 6X magnification. Photographs were taken for further analysis using computer image analysis program. The results were statistically analyzed using Analysis of variance (ANOVA) and Tukey’s honestly significant difference test. Results: The R-Endo retreatment system resulted in a smaller percentage of canal area covered by residual GP/sealer than in other groups, a significant difference was found between R-Endo and Mtwo group and between Hedstrom groups (P < 0.001). The Mean operating time was minimum with R-Endo group while it was found to be maximum with hand files. Conclusion: It was concluded that all test techniques left gutta-percha/sealer remnants within the root canal. The R-Endo retreatment files and Mtwo retreatment files system proved to be an efficient method for removing gutta-percha and sealer from single rooted premolars.

Published: October 2018

AbstractTo compare the condylar guidance values obtained from interocclusal records and the panoramic radiographs in both dentulous and edentulous subjects. Materials & methods: 20 dentulous and 20 edentulous subjects having specific criteria were selected for the cross-sectional descriptive in-vivo study. In the first method, the sagittal condylar guidance values for both the groups were recorded after obtaining protrusive records using HANAU articulator model Wide-Vue, U.S.A. In the second method panoramic radiographs were made of all the edentulous and dentulous subjects in the natural head position and tracings were done of the outline of glenoid fossa and the articular eminence. The angles formed by the lines drawn were measured and the values obtained were compared with those from the inter-occlusal record method. The condylar guidance readings of both dentulous and edentulous subjects obtained from the interocclusal records and those by tracing panoramic radiographic images were compared by Mann Whitney U test and Karl Pearson’s coefficient of correlation test. Results: The condylar guidance values obtained from the interocclusal records were less when compared to the values obtained from tracing the panoramic radiographs. Significant correlation (r=0.9) between the condylar guidance values obtained for left and right sides in interocclusal record group and a moderate correlation (r=0.65) between the condylar guidance values obtained for left and right sides from panoramic radiographs. Conclusion: The results from this study showed that measurement of condylar inclination angles using panoramic radiographs gave higher values, as compared to the inter-occlusal record method. Also, panoramic radiographic method revealed less difference between the condylar guidance values obtained for left and right sides as compared to the articulator method. Although, significant amount of correlation was found between the two methods, variations due to different operators and better radiographic techniques should be further investigated.

Authors: Chitra Prasad ,   Yashpal
Published: October 2018

Abstract
Introduction: Light cured composite resins have become the method of choice in orthodontic bonding procedures worldwide. In recent years, a new primerless orthodontic bonding composite, Heloisit with good bond strength, fluoride release and an advantage of not requiring use of a primer has been introduced. Aims: To compare the bonding characteristics of commonly available self and light cured adhesives with primerless system. Materials and Methods: One hundred twenty extracted human premolar teeth were mounted on similar sized aluminium blocks and were divided into four groups of thirty teeth each. All teeth were bonded with four different bonding systems Group i) Light Cured Primerless orthodontic Composite (Heliosit®, Ivoclar Vivadent, Schaan, Liechtenstein), Group ii) Light Cured Composite Resin (Transbond XT®, 3M Unitek), Group iii) Light Cured GIC (GC Fuji Ortho LC®, GC Corp.), Group iv) Self Cured Composite Resin (Rely-A-Bond®, Reliance, Inc., Illinois, USA) using metallic premolar first premolar brackets (0.022” Ortho Organizers). These were evaluated for shear bond strength using an Instron testing machine. Surface characteristics after debonding were studied under scanning electron microscopy (SEM) and evaluated using the adhesive remnant index (AR Index). Results: Shear bond strength (SBS) of primerless orthodontic light cured Heliosit® composite was clinically significant and adequate for clinical use. It lies intermediate to Transbond XT light-cured composite and Light Cured GIC. The least bond strength was shown by Rely-a-Bond® self-cured composite resin. Conclusions: Heliosit® light cured primerless orthodontic composite can be used for everyday clinical use due to its ideal characteristics of sufficient bond strength and reduced chances of enamel damage at debonding. Additionally, it is primerless and saves valuable clinical time.

Published: October 2018

AbstractHypodontia is the congenital absence of less than six teeth because of agenesis. Congenital absence of tooth (hypodontia) from the dental arch, may occur with any tooth, most commonly being third molars, however, absence of permanent mandibular canine is rare. The absence of teeth may be unilateral or bilateral. There are reports showing unilateral occurrence of permanent mandibular canines but agenesis of bilateral mandibular canines is not well documented in the literature and comprehensive review of literature shows paucity of data pertaining to this anomaly. Here we report one such rare case of congenitally missing mandibular permanent canines bilaterally.

Abstract
Objective: The aim of the study was to compare the canal transportation and centering ability of Rotary ProTaper Next, Hyflex CM and Wave One primary systems using cone beam computed tomography (CBCT) in curved root canals. Materials and Methods: Total 30 freshly extracted maxillary first molars having root canals with curvature between 10°- 20° were divided into three groups of 10 teeth each. All teeth were scanned by CBCT to determine the root canal shape before instrumentation. In Group 1, the canals were prepared with ProTaper Next files, in Group 2 with Hyflex CM files and in Group 3 with Wave One files. After preparation, post-instrumentation scan was performed. Pre-instrumentation and post-instrumentation images were obtained at 3 mm and 6 mm above the apical foramen and were compared using CBCT software. The amount of canal transportation and centering ability were assessed and statistically compared with one way analysis of variance and Tukey honestly significant test. (p<0.05). Results: All instrumentation systems used resulted in some amount of canal transportation. Data obtained suggested that Wave One files caused significantly lesser transportation and remained better centered in the canal than Hyflex CM and Rotary ProTaper Next files. Conclusion: The canal preparation with Wave One files results in lesser transportation and better centering ability than Hyflex CM and ProTaper Next rotary files in curved root canals.

Published: October 2018

Abstract
Background: Along with conventional periodontal surgical therapy, local delivery of antibiotics may provide more effective treatment in smokers by targeting tissue-invasive bacteria. The aim of this randomized, clinical trial was to evaluate the adjunctive effects of subgingivally delivered 0.5% azithromycin (AZM) as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis in smokers versus non smokers. Methods: 38 sites in patients of chronic periodontitis were randomized and categorized into two treatment groups: Group 1 consisted of 19 sites in patients who were smokers and Group 2 consisted of 19 sites in non smokers, who received Scaling and Root Planing (SRP) plus 0.5% azithromycin gel Local drug delivery. Clinical parameters were recorded at baseline, 1 and 2 months. They included probing depth (PD) and clinical attachment level (CAL) and percentage bone fill. Results: Azithromycin resulted in significant improvements in both the groups. Mean decrease in PD in non smokers by the end of 2 months was 3.903mm and in smokers was 3.917mm. Gain in CAL in non smokers by the end of 2 months was 3.879mm and in smokers it was 3.920mm. Mean bone fill at one month for smokers was 15.86% and was 26.58% at 2 months. In non-smokers the mean bone fill was 17.19% at 1 month and 24.03% at 2 months. Conclusions: When compared to the non smokers, the adjunctive use of 0.5% AZM resulted in similar improvement in clinical outcome in the treatment of chronic periodontitis among smokers. Local drug delivery of Azithromycin gel contributed to decrease in probing pocket depth, gain in clinical attachment level and in alveolar bone. The apparent bone regeneration also raises the intriguing possibility that Azithromycin encourages bone formation once tissue inflammation has subsided.
