Abstract:- Finite element method (FEM) or Finite Element Analysis (FEA) is a contemporary research tool for an orthodontist. FEM is an engineering method of calculating stresses and strains in all materials including living tissues. In orthodontics biomechanics is commonly used in describing the reactions of dental and facial structures to orthodontic forces. The study of orthodontic biomechanics requires the understanding of nature of stress and strain induced by orthodontic forces .This article comprehensively reviews the literature on FEM, the methodology involved in it and its application in various specialties of dentistry.
Keywords:- Finite element analysis, Orthodontics.

Abstract:- A study was carried out to isolate endophytic fungi from Ocimum species (Tulsi) and to assess their antimicrobial activity against Pseudomonas aeroginosa, Mycobacterium smegmatis, Salmonella typhimurium, Candida albicans and Penicillium chrysogenum and production of enzymes such as amylase, protease and tyrosinase. In this study forty endophytic fungi were isolated from leaves and branches of Tulsi. Out of forty endophytic fungal isolates, six isolates showed the inhibition activity against test microorganisms done by dual culture method. The isolate P14T1 exhibited a high antimicrobial activity against Candida albicans (22mm). The crude extract of P13T5 isolate showed highest zone of inhibition against Pseudomonas aeroginosa (21mm) by well and disc diffusion method. 50% of fungal isolates found positive for amylase and protease enzymes production and 27.5% showed positive for tyrosinase. The results of the study suggest that endophytic fungi associated with Tulsi are potential agents for antimicrobial activity and production of enzyme.
Key Words:- antimicrobial activity, enzymes, endophytic fungi, Tulsi.

Abstract:- The growing interest in the future of dental applications of robotic dentistry is leading to the emergence of a new field called Nanodentistry. Robots can supposedly induce oral analgesia, Desensitize tooth; manipulate the tissue to re-align and straighten irregular set of teeth and to improve durability of teeth. Further it is possible that robots may be used to do preventive, restorative, curative procedures in future. Using characterization tools, a variety of oral diseases can be understood at the molecular and cellular levels and thereby prevented. Nano-enabled technologies thus provides an alternative and superior approach to assess the onset or progression of diseases, to identify targets for treatment interventions as well as the ability to design more biocompatible, microbe resistant dental materials and implants. We present a brief overview on nanotechnology in dentistry in our article.
Key Words:- nanotechnology, nanodentistry, robots.

Abstract:- Background: Ectopic pregnancy occurs at a rate of about 1-2% of pregnancies and can occur in any sexually active woman of reproductive age. The incidence has been increasing for years and currently two to three times higher than it was 20 or 25 years ago. Objective: To assess the Incidence and Trends of ectopic pregnancy in a tertiary care hospital of Rajasthan and to evaluate the relevance of the risk factors assossiated with it.
Methods: A retrospective study was designed to assess frequency of ectopic pregnancy and to evaluate the relevance of the known risk factors in 3 years period in Jhalawar Medical College. All the datas were collected from case record of patients and determined and charted in an excel sheet. Simple frequencies and percentages were obtained for various variables. Result: The incidence of ectopic pregnancy was 2.46 per thousand of deliveries. Maximum (72.5%) cases were in the age group of 21 to 30 years and most of cases (40%) were nulliparous. About half (47.5%) of cases were suffering from pelvic inflammatory disease. The commonest site of ectopic pregnancy was in ampullo-isthmic region (82.5%).All patients underwent exploratory laparotomy. Majority (45%) underwent total salpingectomy while fallopian tubes were conserved in a few (7.5%) of cases. No mortality encountered in this series. Conclusion: By identifying the risk factors and catching the patient by ultrasonographic examination at the earliest at 6 weeks, it is possible to improve the prognosis to reduce the morbidity and mortality assossiated with ectopic pregnancy.

Abstract:- The 4-thiazolidinones is an important biological scaffold. A series of 4- thiazolidinone derivatives were synthesized from 4-amino benzoic acid. The synthesized compounds were confirmed by IR, 1H-NMR, Mass spectral data. The two synthesized compounds SS5 & SS6 were screened for anti-inflammatory and analgesic activity. Anti-inflammatory activity was evaluated by carrageenan-induced paw edema test and analgesic activity by Eddy’s hot plate method. Both the compounds showed good activity. All the experimental results were statistically significant. The anti-inflammatory and analgesic activity confirmed that the test compound SS6 showed superior activity than SS5. However, the test compounds were found to be less active than the standard drugs used.
Keywords:- Schiff bases; 4-thiazolidinone; Anti-inflammatory; Analgesic activity.
