Finger prosthesis often needs refabrication due to its discoloration following use. This article presents a novel, economical, and cost-effective technique to duplicate the patient׳s existing prosthesis to obtain a new wax replica, which is then clinically tried and processed to obtain new silicone finger prosthesis. This technique requires comparatively less clinical and laboratory steps as to fabricate an entirely new prosthesis. The newly fabricated silicone finger prosthesis has the fit and marginal adaptation of the patient׳s existing prosthesis but the esthetics is improved...

BACKGROUND: Application of principles of electrocautery for hemostasis dates back to prehistoric times. Its modern implementation in various fields of general and head and neck surgeries have been well documented. However its usage in minor oral surgical procedures has gained popularity only recently. Complications associated with electro-surgery in the dental field are relatively rare and there is insufficient literature on its management. CASE REPORT: We present a case report on management of an electrosurgery induced osteonecrosis involving maxillary alveolus of left premolars...

Necrotizing periodontitis is a distinct and specific disease characterized by rapidly progressing ulceration of the interdental gingiva and then spreading along the gingival margins and leading to acute destruction of periodontal tissues. Necrotizing ulcerative gingival lesions are common in developing countries because of poor nutritional status, poor oral hygiene and debilitating conditions. In the developed world it is mostly seen in patients with the HIV infections and other immune system dysfunctions. The exact etiology of the necrotizing lesions is still unknown; however a fuso-spirochaetal infection along with weakened host immune system seems to play a major role in the pathogenesis of these diseases...

Biomechanical preparation is one of the most important steps in endodontic therapy. Rotary instrumentation has facilitated this step. Nowadays the market is flooded with different types of rotary instruments. The present study compared the root dentinal crack formation with continuous rotating versus reciprocating root canal preparation methods. One hundred and fifty freshly extracted teeth were used for the study. They were divided into 5 groups with 30 teeth in each group. Thirty teeth were kept under control group A and no root canal preparation was done for this group...

MicroRNAs (miRNAs) are short, noncoding RNAs that act as key regulators of diverse biological processes by mediating translational repression or mRNA degradation of target genes. Recent studies discovered miRNAs in saliva, and these miRNAs are promising candidates for use as biomarkers of dental diseases. In this review, the results of miRNA studies in the dental field are presented, and a brief overview of the current progress, limitations, and perspectives regarding miRNA biomarkers for dental diseases is given...

Occlusal diagnosis plays an important role in the planning and subsequent delivery of predictable functional and aesthetic restorations and prostheses. Once an occlusal problem is identified there are a number of techniques and materials that can be utilised to record occlusal relationships, subsequently analyse them and incorporate information obtained into the delivery of tooth restoration or replacement. This paper discusses the clinical and technical aspects of occlusal examination and analysis outlining contemporary and traditional techniques in their utilisation...

Restoration of orbital defects with silicone prosthesis has been a well-documented and accepted treatment option. Adhesive retained prosthesis offer the patients with adequate retention and treatment satisfaction. However, marginal breakdown and discoloration are common problems associated with these prostheses, necessitating their refabrication. Fabrication of a silicone orbital prosthesis is time consuming and requires multiple clinical and laboratory procedures. This technical article describes simple and cost effective steps for rapid fabrication of a silicone prosthesis using conventional methods...

Discovery of multiple foreign objects in the root canal is unusual and their removal is often difficult and challenging procedure. Entrapment of the foreign object in the pulp chamber or in root canal usually occur accidentally in children with the habit of chewing or placing various objects in the oral cavity. Clinically it was often encountered in tooth with wide carious lesion, exposed pulp chamber due to trauma or tooth left open for the drainage during root canal treatment. This impacted foreign body may act as a potential source of pain or infection...

BACKGROUND: Avulsion is one of the most serious injuries of the tooth which is most commonly seen in young children and occurs in the upper front teeth. Immediate transplantation of the avulsed tooth is recommended treatment and results in good prognosis although this may not be always possible. CASE REPORT: The present case highlights the 3-year follow-up of delayed replantation (after 15h) of maxillary central incisor which was avulsed due to trauma. The complications seen in the present case were ankylosis and inflammatory resorption, but clinically the tooth was asymptomatic and maintains the esthetics of the individual signifying the importance of delayed replantation even after prolonged extra-oral time...

The copy denture technique is a misnomer for the clinical and laboratory procedures involved in making complete dentures that replicate most of the features of the original prosthesis. The aim is to replicate the good features of an otherwise successful prosthesis that now requires replacement and to alter the poor features and so it is strictly speaking not a copy. There are many purported advantages to this technique which include reduced treatment time, increased patient acceptance especially for the elderly who may not adapt so well to a new prosthesis, maintenance of tooth position and vertical dimension...

BACKGROUND: Matrix Metalloproteinases (MMPs) are directly responsible for pathogenesis of periodontal diseases and their activity is regulated by Tissue Inhibitor of Metalloproteinases (TIMPs). This study was aimed to evaluate changes in gingival crevicular fluid (GCF) levels of MMP-1 and TIMP-1 in periodontal health and disease. MATERIALS AND METHOD: Clinical parameters were recorded and GCF samples were collected from 30 subjects with chronic generalised periodontitis and 20 periodontally healthy subjects...

BACKGROUND: The aim of this study was to evaluate the complications associated with the occurrence and treatment of impacted maxillary canines. METHODS: This retrospective study was conducted on 533 Southern Chinese children and adolescents who attended the Paediatric Dentistry and Orthodontics Clinics and had at least one impacted maxillary canine. The study material included all the documentation files and radiographs of these patients. Complications that had been recorded in the clinical and surgical notes and that could be diagnosed from the available radiographs were noted...

BACKGROUND: Instrumentation of the root surface, results in formation of a smear layer of organic and mineralized debris which serves as a physical barrier, inhibiting new connective tissue attachment to the root surface. The present study advocates the use of an endodontic irrigant MTAD (mixture of tetracycline, citric acid and detergent) as a root conditioning agent. The main aim of the study was to compare the root conditioning ability of an endodontic irrigant MTAD (mixture of tetracycline, acid and detergent) with 17% EDTA (ethylenediaminetetraacetic acid)...
