Published: January 2013

ABSTRACTAimThe current study has been chosen to evaluate the efficacy of calcium hypochlorite as a disinfecting additive for the gypsum products and its effect on compressive and tensile strength of the set material. It is hypothesized that, the addition of calcium hypochlorite to type V dental stone in sufficient quantity to disinfect the material would have no deleterious effect on compressive or tensile strength.Materials and methodsTotal of 160 samples made up of type V dental stone were divided broadly into two groups of 80 samples each for the sake of compressive and tensile strength testing in dry and wet conditions: Out of each group, 10 samples without addition of any disinfectant (0% calcium hypochlorite) was compared with other group of 30 samples after adding disinfectant, i.e. each subgroup containing 10 samples each (0.5, 1.0 and 1.5% calcium hypochlorite).ConclusionWithin limitations of thisin vitrostudy it is assumed to prepare type V dental stone that contains a disinfectant, has adequate compressive strength and tensile strength, and can significantly act against a resistant species likeBacillus subtilis.Clinical significanceWhen calcium hypochlorite was added to dental stone, extra mixing water was required to produce a material of nearly same pouring consistency. The samples, which were put to microbiological tests, showed effective action of disinfectant onBacillus subtilis. No deleterious effect on compressive or tensile strength could be found after putting the selected samples with calcium hypochlorite.How to cite this articleSwain PK, Nagaral SC, Kamalapurker PK, Damineni R.

ABSTRACTAimsVisual and microscopic evaluation of defects caused by torsional fatigue in hand and rotary nickel titanium (NiTi) instruments.Materials and methodsNinety-six NiTi greater taper instruments which were routinely used for root canal treatment only in anterior teeth were selected for the study. The files taken include ProTaper for hand use, ProTaper Rotary files and Endowave rotary files. After every use, the files were observed visually and microscopically (Stereomicroscope at 10×) to evaluate the defects caused by torsional fatigue. Scoring was given according to a new classification formulated which gives an indication of the severity of the defect or damage.Statistical analysisData was statistically analyzed using KruskallWallis and Mann-Whitney U test.ResultsNumber of files showing defects were more under stereomicroscope than visual examination. But, the difference in the evaluation methods was not statistically significant. The different types of defects observed were bent instrument, straightening/stretching of twist contour and partial reverse twisting. Endowave files showed maximum number of defects followed by ProTaper for hand use and least in ProTaper Rotary.ConclusionVisible defects due to torsional fatigue do occur in NiTi instruments after clinical use. Both visual and microscopic examinations were efficient in detecting defects caused due to torsional fatigue. This study emphasizes that all files should be observed for any visible defects before and after every instrumentation cycle to minimize the risk of instrument separation and failure of endodontic therapy.How to cite this articleChakka NVMK, Ratnakar P, Das S, Bagchi A, Kumar S, Anumula L.

ABSTRACT
Children have boundless energy, so, they are continuously engaged in some or the other physical activity. It is seen that when child reaches school age, accidents in the school environment in the form of falls, injuries due to contact sports, fights, abuse, etc. are very common and the main cause of traumatic dental injuries. Trauma may vary from minor enamel chipping or avulsion to extensive maxillofacial damage, more serious neck and brain injury, which may cause pain, disfigurement and mental agony, having immediate and long lasting effects.
In such cases, a school teacher is in the right position to handle such an emergency and refer the child to the concerned dental surgeon or a pedodontist for further needful care. The main reason for delayed treatment of dental trauma is that people present at the site of injury are unaware of protocol of rapid and appropriate management leading to improper first aid treatment.
The purpose of this study was to investigate the awareness of a group of school teachers from different schools about the prevention and emergency management of dental trauma in school children, by means of a questionnaire. Then educating them and reassessing their knowledge after a period of 3 months. Unfortunately, the public is unaware of the risks and does not have enough information about first aid emergency treatment or to avoid traumatic injuries.

ABSTRACT
People with HIV/HBsAg in India frequently encounter discrimination while seeking and receiving health care services. The knowledge and attitudes of health care workers (HCWs) influences the willingness and ability of people with HIV/HBsAg to access care, and the quality of the care they receive. The objective of this study was to asses HIV/HBsAg-related knowledge, attitudes and risk perception among students and dental HCWs. A cross-sectional survey was conducted on 250 students and 120 dental HCWs in the form of objective questionnaire. Information was gathered regarding demographic details (age, sex, duration of employment, job category); HIV/ HBsAg-related knowledge and attitudes; risk perception; and previous experience caring for HIV-positive patients. The HCWs in this study generally had a positive attitude to care for the people with HIV/HBsAg. However, this was tempered by substantial concerns about providing care, and the fear of occupational infection with HIV/HBsAg. A continuing dental education program was conducted to resolve all the queries found interfering to provide care to HIV/HBsAg patients. But even after the queries were resolved the care providing capability was not attained. These findings show that even with advanced knowledge and facilities the attitude of dental HCWs and students require more strategic training with regards to the ethics and moral stigma associated with the dreaded infectious diseases (HIV/HBsAg).

Tissue Resistance to Soft Tissue Emphysema during Minimally Invasive Periodontal Surgery
Authors: Harrel Stephen K , Abraham Celeste M , Rivera-Hidalgo Francisco 
Published: January 2013

ABSTRACT

Aim
The aim of this study was to determine the pressure where oral soft tissue resistance will be overcome resulting in soft tissue emphysema and to measure the safety of an antifouling device for a videoscope used during minimally invasive periodontal surgery.

Materials and methods
Resistance was measured in vitro in porcine tissue. One study arm measured palatal tissue resistance to air applied through a needle. Another arm measured resistance in a surgical access for minimally invasive periodontal surgery (MIS). India ink was placed on the tissue, pressure at 0,3,10,15,20, and 25 pounds/square inch (psi) applied, and penetration of India ink into the tissue was measured. Three trials in three sites were performed at each pressure in both arms of the study.

Results
Pressure applied to palatal tissue through a needle showed no significant penetration of India ink until 15 psi (0.90 ¡Ó 0.24 mm, p = 0.008). Penetration considered clinically significant was noted at 20 and 25 psi (4 to 6 mm, p „T 0.0001). No significant penetration was noted in minimally invasive incisions.

Conclusion
Within the test system, pressures of 15 psi or less seem unlikely to cause soft tissue emphysema. No evidence of tissue emphysema was noted with the videoscope antifouling device.

Clinical significance
The use of pressures greater than 15 pounds per square inch should be avoided during surgical procedures. The antifouling device for a videoscope appears safe for use during minimally invasive periodontal surgery.

ABSTRACTAimTo present a unique case of mandibular first and second premolars with two roots and two root canals with the aid of spiral computed tomography (SCT).BackgroundConfirmation of morphology of mandibular first and second premolars with the aid of SCT.Case descriptionMandibular premolars usually have a single root and a single canal. The occurrence of two roots with two separate root canals is extremely rare. The use of SCT in this rare case greatly contributed toward making a confirmatory diagnosis and successful endodontic management.ConclusionSuccessful nonsurgical endodontic management of mandibular first and second premolars with two separate roots and root canals has been presented. In this case, exact root canal anatomy could not be confirmed by using radiographs alone. Hence, the use of SCT helped us in making a confirmatory diagnosis.Clinical significanceDevelopmental anomalies can occur in any tooth and two rooted premolars are no exception. The complexity of such teeth has to be considered for planning endodontic treatment using latest diagnostic equipment to increase the chances of success.How to cite this articleReddy SJ, Chandra PVR, Santoshi L, Reddy GV.

Published: January 2013

ABSTRACT

Aim
The present case report describes the importance of understanding of biomechanical and clinical considerations in application of Forsus appliance in correction of class II skeletal malocclusion.

Background
Angle's class II malocclusion is one of the most prevailing that may be either skeletal or dental presenting with different clinical manifestations. There are number of appliances to treat such a malocclusion in a growing child. Fixed functional appliances are indicated for class II corrections in patients who report late with minimal residual growth left.

Case description
A case of class II skeletal and dental malocclusion treated with preadjusted edgewise appliance supplemented with Forsus Fatigue Resistant Device (FRD) (3M Unitek Corp, California, USA) is reported.

Conclusion
Forsus device is an effective alternative in treating moderate skeletal class II malocclusion. The Forsus FRD (3M Unitek Corp, California, USA) can be used instead of class II elastics in mild cases and in place of Herbst appliance in severe cases.
Alteration of force vector by modifying the archwire as shown in this case report while applying Forsus and incorporation of 10 degree labial root torque in lower archwire will minimize the effects on dentition.
Engaging modules or tubing on to the pushrod and leaving 1 to 2 mm clearance between distal end of the upper tube and L-pin as shown in this case report will significantly improve the patient compliance.

Clinical significance
Much emphasis should be given to biomechanical considerations which were discussed in this article while treating patients with Forsus to prevent the unwanted effects.
Clinical considerations and certain modifications advised in this case report should be utilized while treating class II skeletal malocclusions with Forsus appliance to eliminate the patient cooperation factor and make treatment time estimates much more accurate.

Authors: Sreekumar AV , Narasimhan HV , Dheeraj D , Darshana D 
Published: January 2013

ABSTRACT
Treatment planning, reconstruction and rehabilitation of maxillofacial and dental defects have always been a challenge for a maxillofacial surgeon. Reconstruction of the oral cavity is often a difficult task as it involves the restoration of both the esthetic or cosmetic form as well as the preoperative function. Understanding the oral cavity anatomy as well the functional capacities of its various subunits is required to achieve good results.
The recent advances in treatment planning, diagnostic imaging and reconstructive techniques, especially in the field of osseointegration, tissue expanders, perforator flaps, microvascular free tissue transfer and bone engineering, have yielded excellent functional and esthetic outcomes. This article provides a brief overview on various advanced reconstructive and rehabilitation techniques available in contemporary clinical practice.

Effects of Eurythmy Therapy in the Treatment of Essential Arterial Hypertension: A Pilot Study
Authors: Zerm Ronald , Lutnæs-Mast Froeydis , Mast Heiner , Girke Matthias , Kröz Matthias 
Published: January 2013

Introduction: Although eurythmy therapy (ET) has been used in the context of anthroposophic medicine (AM) for the treatment of, among other conditions, arterial hypertension (AH) for more than 80 years, there are as yet no studies on its effectiveness on disease entity. However, it has been shown that ET can increase heart rate variability comparably to ergometer training. Objective: To determine whether a 10-week course of ET has an impact on AH and if so, to determine the strength of the effect. The impact of ET on state-autonomic regulation, self-regulation, internal coherence, and quality of life is also explored. Methods: Consecutive inclusion of 9 subjects (6 female, 3 male, mean age of 64 years, SD 8.26) with AH diagnosed by their general practitioners. Inclusion criteria: no or unchanged antihypertensive medication from 4 weeks prior to the start of the study until the end of the study. ET was carried out with weekly instruction along with a daily, home-based program for 10 weeks with specific exercises. Twenty-four—hour blood pressure (BP) measuring was carried out, and the questionnaires were administered before and after the intervention. In addition, after a further 6 months during which 8 of the 9 patients carried on with the exercises of their own accord, the aforementioned parameters were assessed for a third time. Results: Parameters of the 24-hour BP measurements show a moderate, but not significant, improvement immediately after the intervention and 6 months after the intervention. After the 10-week intervention, we saw an improvement of the State-autonomic Regulation questionnaire, the subscale on “Rest/Activity regulation,” of the Self-regulation questionnaire, and the subscale “Initiative and Interest” of the Herdecke Quality of Life Questionnaire (HLQ) (all P < .045). After the 6-month post-study observation period, the aforementioned parameters improved further still, and an additional, significant improvement was seen for the Trait-autonomic Regulation subscale “Rest/Activity regulation,” the HLQ-sum score, and the HLQ subscales “social interaction,” “mental balance,” and “physical ability.” Conclusion: A 10-week course of ET does not result in a significant improvement in BP. The average BP measurements improved postintervention by an absolute 3.2/2.0 mmHg and after 6 months of independent continuation of ET by 6.3/4.4 mmHg (systolic/diastolic). Despite the small group size, the regulation and quality-of-life parameters improved significantly after the intervention and further still after the 6-month observation period. The results need to be validated with larger patient collectives and control groups.

Authors: Quilty Mary T. , Saper Robert B. , Goldstein Richard , Khalsa Sat Bir S. 
Published: January 2013

Background: Yoga is a mind-body exercise practiced by nearly 16 million US adults. Clinical yoga research has yielded promising findings in physical and mental health outcomes. However, research in non-patient populations is limited. The purpose of this study is to survey a non-clinical population to better understand yoga use in a real-world setting. Methods: This study used a pre-post test design in a convenience sample of adults registered for a 4-week beginner yoga program within a network of five yoga studios in Austin, Texas. Students were linked via e-mail to baseline and endpoint surveys. Analyses were descriptive. Results: Six hundred four students completed the baseline survey, and 290 (48%) completed the 4-week endpoint survey. Baseline demographics were similar to those in national surveys, with respondents being primarily female (86%), white (88%), and college educated (78%). The primary barrier to practice was time (55%). Respondents perceived yoga primarily as an exercise activity (92%), spiritual activity (73%), or a way to manage or treat a health condition (50%). Main reasons for taking yoga were general wellness (81%), physical exercise (80%), and stress management (73%). Ninety-eight percent believed yoga would improve their health, with 28% taking yoga to alleviate a health condition. On average, respondents practiced 3 to 4 hours/week in and out of class. Conclusions: Respondent demographics were consistent with national survey data. Data show that yoga is perceived several ways. Information on practice patterns provides new information, which may improve understanding of how non-clinical populations incorporate yoga into daily life for health management.
