Videotaped Feedback Method to Enhance Learning in Preclinical Operative Dentistry: An Experimental Study.

The aim of this study was to investigate if a videotaped feedback method enhanced teaching and learning outcomes in a preclinical operative laboratory setting for novice learners. In 2013, 60 dental students at a dental school in India were randomly assigned to two groups: control (n=30) and experimental (n=30). The control group prepared a Class II tooth preparation for amalgam after receiving a video demonstration of the exercise.

Management of apicomarginal defect in esthetic region associated with a tooth with anomalies.

Tooth related factors such as palatoradicular groove can be one of the causes for localized periodontal destruction. Such pathological process may result in apicomarginal defect along with inflammation of pulp. This creates challenging situation which clinician must be capable of performing advanced periodontal regenerative procedures for the successful management.

Solitary Peripheral Osteoma of the Angle of the Mandible.

Solitary peripheral osteoma is a benign, slow-growing osteogenic tumor arising from craniofacial bones such as the sinus, temporal, or jaw bones but rarely originating from the mandible. Osteoma consists of compact or cancellous bone that may be of peripheral, central, or extraskeletal type. Peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass.

In this study, C.rectus was detected and quantified by using 16s rDNA based PCR in chronic periodontitis and compared with the levels of serum iron, total iron binding capacity and transferrin in chronic periodontitis and healthy sites.

Association of Herpes Viruses with Mild, Moderate and Severe Chronic Periodontitis.

Introduction: Periodontal disease is an inflammatory condition of the supporting tissues of the teeth. It is a multi-factorial and multi-etiological infectious disease process. Recent evidences shows that human herpes viruses could be putative pathogens.

Adverse Reaction of Sodium Hypochlorite during Endodontic Treatment of Primary Teeth.

Sodium hypochlorite (NaOCl) is the most common and effective intracanal medicament used in root canal treatments, because of its low-cost and a very effective antimicrobial activity against microbiota of infected root canals. Sodium hypochlorite is an effective intracanal irrigant and is used in concentrations ranging from 0.5 to 5.

Karyotype, Pedigree and cone-beam computerized tomography analysis of a case of nonsyndromic pandental anomalies.

This case report presented a karyotype and pedigree analysis of a case with unusual combination of dental anomalies: Generalized short roots, talon cusps, dens invagination, low alveolar bone heights, very prominent cusp of carabelli and protostylid on first permanent molars, taurodontism of second permanent molars, rotated, missing and impacted teeth. None of the anomalies alone are rare. However, until date, nonsyndromic pandental anomalies that are affecting entire dentition with detailed karyotype, pedigree and cone-beam computerized tomography analysis have not been reported.

An osteoma is a benign, slow growing osteogenic tumor characterized by proliferation of either compact or cancellous bone. It can be central, peripheral or extraskeletal. Clinically osteomas are usually asymptomatic.

Endodontic management of maxillary first molar with type I canal configuration- a rare case report.

Thorough knowledge about the root canal variations is essential for the predictable endodontic treatment outcome. The root and root canal anatomy of maxillary first molar varies greatly. A Pub-med literature search about single rooted single canalled maxillary first molar was done to know its details such as incidence, diagnostic method used, age, sex and ethnic background of patient.

Quantification of Selenomonas sputigena in Chronic Periodontitis in Smokers Using 16S rDNA Based PCR Analysis.

Background And Aim: Selenomonas species have been associated with chronic periodontitis and have been implicated in converting periodontal health to disease. Scanty literature is available in Indian population. Hence, the objective of the study was to detect the prevalence of Selenomonas sputigena in healthy and chronic periodontitis by polymerase chain reaction (PCR) in Indian population and to check whether smoking affects the subgingival microflora of this organism in chronic periodontitis.

Keratoameloblastoma a rare entity: a case report.

Ameloblastoma is the second most common odontogenic tumour of oral cavity; which has several different histological variants such as follicular, plexiform, acanthomatous, granular cell, desmoplastic, basal cell, clear cell, hemangiomatous, mucous cell differentiation and keratoameloblastoma. It is common in posterior mandible and has high male predilection in the ratio of 3:1. This report presents a case of keratoameloblastoma in 65-year-old female patient in the anterior mandible region with literature review on clinical features, histopathological findings, radiological appearance and treatment options.

The teratoid cyst is a rare variant of the dermoid cyst which seldom occurs in the oral cavity. If seen, they generally present as slow growing cysts of the floor of mouth, reported commonly in the 2(nd) and 3(rd) decade of life in males. Histopathologically, dermoid cyst is classified as epidermoid cyst, true dermoid cyst and teratoid cyst depending on the presence of adnexal structures and derivatives of all three germ layers.

Introduction of Mini-CEX in undergraduate dental education in India.

Background: Some assessment methods of clinical learners have limitations so that students might not reflect their performance in actual clinical situations. Educational research has so far not yielded a single 'gold-standard' performance assessment tool. Mini-CEX (clinical evaluation exercise) is an instrument intended for work-based assessment of actual clinical performance, including a range of skills like communication and humanistic qualities.

Non viral vectors in gene therapy- an overview.

Non-viral vectors are simple in theory but complex in practice. Apart from intra cellular and extracellular barriers, number of other challenges also needs to be overcome in order to increase the effectiveness of non-viral gene transfer. These barriers are categorized as production, formulation and storage.

A Comparison of Parental Satisfaction in the Quality of their Child's Orthodontic Treatment by Orthodontists and Pedodontists.

Background: The aim was to evaluate satisfaction of the parents of children who have undergone orthodontic treatment provided by their orthodontists and pediatric dentists in their private practice.

Materials And Methods: A total of 412 parents were interviewed with the help of a questionnaire containing information such as demographic part, experience of braces, motives for orthodontic treatment, complications faced during the procedure and reasoning for satisfaction. Student's t-test was applied to analyze the results.

Endodontic management of maxillary first molar with seven root canals diagnosed using Cone Beam Computed Tomography scanning.

The main objective of root canal treatment is thorough cleaning and shaping of the entire pulp space and its complete filling with an inert filling material. A major cause of post-treatment disease is the inability to locate, debride or adequately fill all canals of the root canal system. The form, configuration, and number of root canals in the maxillary first molars have been discussed for more than half a century.

Complete oral rehabilitation in a case with severe dental fluorosis.

The authors have presented a technique of full occlusal rehabilitation in a case of severe dental fluorosis. In this technique, maxillary and mandibular anterior teeth were simultaneously prepared and restored first. This was followed by simultaneous preparation of maxillary and mandibular posterior teeth that were restored in canine guided occlusion.
