Lichen planus is a common mucocutaneous disease in adults. Childhood lichen planus is an extremely rare entity which is characterized by violaceous, scaly flat topped polygonal papules with the oral involvement being extremely uncommon. Early and correct diagnosis is very important to avoid further complications. We report a nine year old boy with disseminated lichen planus involving the flexor aspect of the wrists and legs as well as, oral and genital mucosal involvement which regressed after treatment. This is to add another case of lichen planus in a child and to emphasize its consideration in the differential diagnosis of oral mucosal white patches in children.

Purpose: The aim of this study was to compare the microleakage of glass ionomers (conventional and resin modified) with that of recently introduced nanoionomers. Materials and Methods: Standardized class I and class V cavities were prepared on 120 young permanent teeth. Samples were equally divided into group I (class I restorations) and group II (class V restorations), and further divided into subgroups. The subgroups were restored with Fuji IX, Fuji II LC, and newly introduced Ketac™ N 100 (KN 100). Samples were thermocycled and submerged in Acridine dye for 24 h. Samples were sectioned to view under fluorescent microscope and marginal leakage was evaluated by Chi-square and Kruskal - Wallis test. Results: Fuji IX showed the maximum leakage, followed by LC II and the least was observed in KN 100. In class I restorations, there was significant difference while comparing Fuji IX with Fuji LC II and KN 100 and nonsignificant difference between LC II and KN100. In class V restorations, Fuji IX and KN100, KN 100 and LC II showed significant difference. Fuji IX and LC II showed nonsignificant difference. Conclusion: Within the limitations of this study, Fuji IX showed the maximum microleakage. KN 100 showed minimum leakage, better sealing ability, and was more consistent. © Journal of Natural Science, Biology and Medicine.

Aims and objectives: (1) To understand the molecular level mechanism involved in immune evasion leading to primary HSV infection. (2) To explain the neuronal latency of herpes simplex virus. (3) To explain the reason for the specificity in the sites of primary and recurrent HSV lesions. Methods: A systematic review was done to understand the molecular level mechanism involved in primary, latency and recurrent herpes simplex infections. We prepared this article by compiling the data from various textbooks, literatures and PubMed, Embase, and EBSCOhost databases. Results and conclusion: Herpes simplex virus is a highly contagious human pathogen that has widespread infections in the oro-facial region which is associated with HSV-1. This single review article can provide the entire knowledge about the pathogenesis, its interesting property of latency and clinical features of HSV infection under one tree. Thus, this article enlightens the dental professionals with an adequate knowledge about the pathogenesis, clinical manifestations and specific sites of primary and recurrent lesions which will highly help them in timely diagnosis, management and also for controlling the spread of infection. © 2016 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

Background: Numerous restorative materials are being used in dentistry to achieve adequate strength and restore aesthetics. However, a perfect ideal restorative material has still eluded dentist. Dental amalgam is versatile material with self-sealing property, but is unaesthetic. Other restorative materials like, composites require conservative preparation, but exhibits polymerisation shrinkage resulting in microleakage. To overcome these drawbacks a high strength restorative material reinforced with ceramic and zirconia fillers known as zirconomer has been introduced. The aim of this study was to evaluate the micro-leakage of these three different restorative materials. Materials and Methods: Thirty non-carious human permanent first and second molars were utilized in this study. Class I cavities were prepared on the occlusal surface; cavities were then restored with amalgam, composite and zirconomer as per manufacture’s instruction. All samples were stored for 24 hours in distilled water followed by thermocycling. The entire tooth surface was painted with two coats of varnish to within 1mm of the restoration margins. The teeth were immersed in dye. Teeth were sectioned and observed under stereomicroscope. Result: In this study the zirconomer exhibited the highest micro leakage as compared to composite and amalgam but composite having higher micro leakage as compared to amalgam and lower micro leakage as compared to zirconomer. Conclusion: Even though composite and amalgam are being marketed aggressively and new material like zirconomer are on origin, amalgam still proves to be one of the best materials. © 2015, Journal of Clinical and Diagnostic Research.
