Oral submucous fibrosis has a high rate of morbidity because it causes a progressive inability to open the mouth, resulting in difficulty in eating and consequent nutritional deficiencies. Oral submucous fibrosis also has a significant mortality rate because it is a premalignant condition and malignant transformation has been noticed. Here, we report the role of collagen membrane in surgical management of OSMF Grade-IV.

Artificial denture ingestion is a multidisciplinary problem. Not only artificial but fixed dentures are also at high risk of ingestion or aspiration in case of their spontaneous or traumatic dislodgement. Clinical presentation of denture ingestion varies with the site of impaction and its associated complications with passage. It is an uncommon problem requiring awareness of many specialists including dentists, surgeons, otolaryngologists and anesthesists. Complications include obstruction, bleeding, perforation fistulae with neighbour organs. Here a patient presented to casualty with symptoms of sub-acute intestinal obstruction after alleged history of artificial denture ingestion. Patient was operated and denture was retrieved from transverse colon.

Over the course of time, dentistry has evolved from a primitive form of dental care to modern day use of preventive treatment modalities. In today’s modern dentistry with the availability of various new obturating materials, it was interesting to accidently diagnose the root canal being obturated with stainless steel wire. Here, we report a unique case where the root canal of a 10 year male patient was obturated with stainless steel wire following which the patient developed persistent pain and infection.

Forensic dental fieldwork requires an interdisciplinary knowledge of dental science. Barr bodies are known to arise from inactivation of x- chromosome in a female cell, so it also has been used as a reliable method for sex determination. The objective of this study is to evaluate the reliability and accuracy Buccal Barr bodies for sex determination. The study was conducted on 100 subjects, (50 males and 50 females) with an age range of 20 to 36 years. The method was applied on each subject and the data was collected. After obtaining the data it was coded, analysed, decoded, interpreted and statistically analysed. The sensitivity and specificity of buccal barr bodies was found to be 24% and 84% respectively with an accuracy of 54%. It is concluded that buccal Barr bodies have the accuracy (54%). Hence it can be one of the reliable parameter but more studies are required to justify role in forensic odontology for sex determination, but certain circumstances like delay in sample staining, storage incapability can alter the results. Hence, more samples with accurate sample collection and storage technique can provide better results.

Platelet-rich fibrin (PRF) was first described by Choukroun et al. in France. It has been referred to as a second-generation platelet concentrate, which has been shown to have several advantages over traditionally prepared PRP. It’s a new generation of platelet concentrates geared to simplified preparation without biochemical blood handling. This article describes the evolution of this novel platelet concentrate and its applications in the field of Oral and Maxillofacial Surgery.

Waxes, included beeswax, as one of the most versatile natural substances ever used by man, have already been used in people’s life widely for a long time. Current dental waxes are mixture of paraffin’s, microcrystalline waxes, natural and synthetic raw materials. However, waxes characterize same disadvantage as plasticity and law stability of volume after melting and cooling. Aim of this study was to investigate the influence of different paraffin’s and microcrystalline waxes on the properties of base plate waxes. Fife new compositions (S1-S5) were compared to four commercial products like base plates from Modelling wax, Modelling wax, Modellierwachs rosa standard, Modelling wax Ceradent. The plasticity and the volumetric shrinkage of the waxes after melting and cooling were measured. Samples S1-S5 to reflect of the requirements of the ISO standard and have the proper plasticity. Changing the paraffin’s and microcrystalline waxes have a big influence on the plasticity of the final composition. Microcrystalline waxes decrease the wax contraction. Shrinkage after heating up to 110oC and cooling to 68oC is changing from one wax to other Modelling wax (Interdent) 4.5%, Modeling Wax Ceradent (Spofa) 8.9%, Modelling wax (Bredent) 9.8%, Modellierwachs rosa (Bego) 11.9%. During the re-melting process (inside wax warmers) waxes can change their properties like flowing and volumetric shrinkage due the thermal degradation. Such process can be reducing by producer adding thermal stabilizer, but this material can be consumed after several cycles. From clinical point of view is not recommended to heat and re-melt the base plate waxes for long time in wax warmer especially at higher temperatures.
