Background: The purpose of this study was to study the drug sensitivity pattern of Candida seen in HIV seropositive patients in Chennai, South India. Materials and Methods: 36 oral rinse samples were collected from HIV seropositive individuals with (21 patients) and without (15 patients) clinical candidiasis. The type of Candidiasis, quantitative estimation, differentiation of candida species and antifungal susceptibility testing was done using different tests. Results: In the 21 patients with candidiasis, pseudomembranous type predominated with low CD4 counts and high colony forming units. Antifungal Drug sensitivity test revealed resistance to fluconazole which is attributed to long term exposure to the drug. Conclusion: The results of the study confirm the hypothesis that candidal species can be isolated in HIV positive patients with clinical candidiasis. In HIV infection there are fluconazole resistant candida species emerging mainly due to long term exposure to the drug.

Introduction: Dental casting alloys have found widespread usage in restorative dentistry owing to their physical, biological and economical properties. Recent technologies have been applied to these alloys to improve their utility, longevity and efficiency. Purpose of the Study: The current study aimed at evaluation of recast base metal nickel-chromium alloy with or without addition of new alloy based on their mechanical properties. Materials and Methods: The study evaluated 10 samples each of fresh alloy, recast alloy with addition of 50% of wt. of new alloy and recast alloy without addition of new alloy. Samples were subjected to computerized Universal Testing Machine and mechanical properties viz. tensile strength, yield strength, percentage of elongation, modulus of elasticity and microhardness was tabulated. Data was subjected to multiple posthoc test of significance. Results: Significant changes were observed in recast alloy with and without addition of new alloy in contrast to fresh alloy. Conclusion: Recast alloys used in fixed dental prostheses without addition of new alloy show degenerative changes when compared to unused alloys after casting.

Self-injurious behavior is a deliberate alteration or damage without suicidal intent. Herein, we report a patient who had caused intentionally self-trauma to his left lower permanent canine and placed a long metallic foreign body into the root canal. History revealed a habit of placing metallic objects in the form of stapler pins into the mouth, but closer examination revealed the habit to be more as a method of self-injurious behavior. Following an episode of severe pain, the tooth was endodontically treated after removal of the foreign body that was corroding. Clinical significance of the case report is that the patient may just be put off as having a habit of inserting foreign objects into the mouth, but the behavior was more self-injurious in nature.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign, highly vascular, and locally aggressive tumor that predominantly occurs in adolescent males. Usually, the presenting symptom is a painless nasal obstruction or epistaxis; however, other symptoms may develop depending on the size and extent of the tumor mass. Owing to the vascularity of the tumor, incisional biopsy is not attempted. The diagnosis is dependent on multiplanar imaging modalities like Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Angiography. These imaging modalities help in assessing the tumor mass, pre-operative embolization of the feeder vessel, and treatment planning. Usually, patients with JNA are diagnosed by otorhinolaryngologists, but here, we present a rare case of JNA reporting to the dental hospital due to a tender palatal swelling. © 2013 Mishra S.

Dental caries is a disease with multifactorial causes. The prevalence and incidence of dental caries in a population is influenced by a number of risk factor such as sex, age, socioeconomic status, dietary patterns and oral hygiene habits. Thus the present study was designed to assess the prevalence of dental caries in school children in Chidambaram between 5-15 age groups. Materials and methods: The study population consisted of 2362 children, 1258 were boys and 1104 were girls. A total of 7 schools were selected. Trained Dental Surgeon was involved in the examining and the children were examined according to the Dentition status and Treatment Needs, WHO oral health assessment 1987.Results: Off all the three groups, group II (9-11yrs old) should high percentage of caries. In total, dental caries were observed in 1484(63.83%) of study population. The mean (+SD) value of dmft/DMFT of all groups, the decayed teeth accounted for the greatest percentage. In all 80.4%of the student belongs low socio-economic group has showed dental caries. Restoration was the most required treatment in all three groups which was follow by pulp therapy. Conclusion: The result of this study is a pointer to the fact that there still exist a large segment of the population who continue to remain ignorant about the detriment effects of poor oral health and the multiple benefits enjoyed from good oral health.

Loricrin is a terminally differentiating structural protein comprising more than 70% of the cornified envelope. It contributes to the protective barrier function of the stratum corneum. In vivo, loricrin is expressed in all mammalian stratified epithelia with the highest levels of expression in humid tissues such as newborn epidermis, the epithelia of oral and anal mucosa, esophagus, foreskin, vagina and the epidermal parts of sweat ducts. Loricrin is not expressed in non keratinizing epithelia and its expression at these sites actually represents a defensive or protective mechanism of the body. An insight into this protein- Loricrin can shed light to its potential as a marker in the early stages of potentially malignant disorders like oral sub mucous fibrosis and leukoplakia. This compilation has been done by taking into account the existing literature, reviews and original studies on loricrin, a major component of the cornified cell envelope, its structure and the alterations that result due to its absence or presence of both the epidermis and the oral mucosa.

Histopathology lab is the place where the specimen gets processed and stained to view under microscope for interpretation. Exposure to the chemicals used in these processes cause various health hazards to the laboratory technicians, pathologists, and scientists working in the laboratory. Hence, there is a dire need to introduce healthy and bio-friendly alternatives in the field. This literature review explores the natural products and their efficiency to be used as alternatives for chemicals in the histopathology lab.

Personal identification has a pivotal role in forensic investigations. Gender determination is an essential step in personal identification. Despite the advent of advanced techniques such as DNA fingerprinting, methods such as lip print and fingerprint analysis and mandibular canine index calculations are routinely used in gender determination, as they are simple and cost-effective. The present study investigated the hypothesis that lip print analysis is an effective tool in gender determination compared with fingerprint analysis and the mandibular canine index. The predominant patterns of lip prints and fingerprints were analyzed in males and females, and the efficacy of the mandibular canine index in gender determination was evaluated. The study group comprised 50 students, 25 males and 25 females who were 18-25 years of age. Lip prints and fingerprints were obtained and classified according to Tsuchihashis classification and Kcken and Newells classification, respectively. Mandibular impressions were made and the mandibular canine index was calculated. Type I and Type I lip prints were predominant in females, and Type IV lip prints were predominant in males. The analysis of fingerprints revealed that the loop fingerprint pattern was predominant in both males and females. The mandibular canine index was not found to be significant in gender identification. The predominant patterns of lip prints were distinct for males and females; conversely, fingerprints were demonstrated to be similar in both genders. Therefore, lip prints hold an increased potential for gender determination, as compared with fingerprints, and the mandibular canine index is not a reliable indicator of gender.

The aim of this study was to evaluate the release of nickel and chromium ions in human saliva during fixed orthodontic therapy.Ten patients with Angles Class-I malocclusion with bimaxillary protrusion without any metal restorations or crowns and with all the permanent teeth were selected. Five male patients and five female patients in the age group range of 14 to 23 years were scheduled for orthodontic treatment with first premolar extraction. Saliva samples were collected in three stages: sample 1, before orthodontic treatment; sample 2, after 10 days of bonding sample; and sample 3, after 1 month of bonding. The samples were analyzed for the following metals nickel and chromium using inductively coupled plasma optical emission spectrometry (ICP-OES).The levels of nickel and chromium were statistically significant, while nickel showed a gradual increase in the first 10 days and a decline thereafter. Chromium showed a gradual increase and was statistically significant on the 30th day.There was greatest release of ions during the first 10 days and a gradual decline thereafter. Control group had traces of nickel and chromium. While comparing levels of nickel in saliva, there was a significant rise from baseline to 10th and 30th-day sample, which was statistically significant. While comparing 10th day to that of 30th day, there was no statistical significance. The levels of chromium ion in the saliva were more in 30th day, and when comparing 10th-day sample with 30th day, there was statistical significance.Nickel and chromium levels were well within the permissible levels. However, some hypersensitive individuals may be allergic to this minimal permissible level.

In recent years, direct metal laser sintered (DMLS) metal-ceramic-based fixed partial denture prostheses have been used as an alternative to conventional metal-ceramic fixed partial denture prostheses. However, clinical studies for evaluating their long-term clinical survivability and acceptability are limited.The aim of this study was to assess the efficacy of metal-ceramic fixed dental prosthesis fabricated with DMLS technique, and its clinical acceptance on long-term clinical use.The study group consisted of 45 patients who were restored with posterior three-unit fixed partial denture prosthesis made using direct laser sintered metal-ceramic restorations. Patient recall and clinical examination of the restorations were done after 6months and every 12 months thereafter for the period of 60 months. Clinical examination for evaluation of longevity of restorations was done using modified Ryge criteria which included chipping of the veneered ceramic, connector failure occurring in the fixed partial denture prosthesis, discoloration at the marginal areas of the veneered ceramic, and marginal adaptation of the metal and ceramic of the fixed denture prosthesis. Periapical status was assessed using periodical radiographs during the study period. Survival analysis was made using the Kaplan-Meier method.None of the patients had failure of the connector of the fixed partial denture prostheses during the study period. Two exhibited biological changes which included periapical changes and proximal caries adjacent to the abutments.DMLS metal-ceramic fixed partial denture prosthesis had a survival rate of 95.5% and yielded promising results during the 5-year clinical study.
