Abstract: Introduction: Bioceramic technology has been introduced recently in endodontics to benefit from the hydroxyapatite formation during the setting reaction in the presence of tissue fluid and establish a chemical bond at the dentin interface. Aim: To compare the physiochemical properties (pH changes, releasing elements and solubility) of different newer Bioceramic sealer (Ceraseal) with mineral trioxide aggregate (MTA-Fillapex) sealers. Material and Method: Samples were prepared by using three different injectable sealer placed in 20 ring moulds, 10 of each sealer. Each sample was prepared with an internal diameter of 10 mm and a height of 3mm. The samples were digitally weighed to register the mass of each specimen before and after immersion in distilled water. The pH value was measured by a digital pH meter, releasing elements measured in atomic absorption spectrophotometer, and solubility measured in digital weighed machine. After 1, 7, 14 and 28 days, pH changes, released elements and solubility was the data obtained calculated and statistically analysed. Results: Ceraseal Sealer exhibited high alkaline pH over time and also showed significantly higher solubility (P < 0.05). Conclusion: Bioceramic sealer shows more alkalinity and calcium ion release compared to the MTA sealer. The alkalinity nature of the bioceramic sealer, corresponds to the increase in solubility. So bioceramic sealer are more alkaline, calcium releasing and soluble.

The porcelain veneer is very esthetic and conservative treatment modality for many indications. The success of porcelain veneer depends very much on the method of fabrication and most importantly case selection. An attractive appearance with veneer has shown to increase people’s self-confidence, personal relationship, and even the success in his or her career. Hence with veneer, it is possible to create amazing esthetic results and yet retain considerable solid tooth structure.

Burns of head and neck region causes skin contracture which will result in microstomia and loss of skin flaccidity. The prevention and management of microstomia contracture is an important aspect of facial burn. The goal of microstomia repair include the reconstruction of orbicularis sphincter for adequate lip functioning, obtaining lip symmetry and well positioned scar and adequate mouth opening. The standard treatment for the prevention and management of contracture includes compression therapy, grafting, mouth splinting, scar massage, excercise, patient education. These types of maxillofacial prosthetic appliances may be indicated, in conjunction with or without surgery these appliances can be use to improve the reduced mouth opening caused by burns or other traumatic injuries With proper education and motivation of operator and the patient use of these appliances will not only improve the reduced mouth opening but also improve form, function, esthetics, and also enhance the patient’s quality of life.

The purpose of this narrative review is to comprehensively assess and enhance the understanding of the components, workflow and applications of dynamic navigation system in endodontics. Dynamic navigation system is vastly used by oral and maxillofacial surgeons for implant and its use in endodontics has recently been gaining momentum. By offering real time visualization of the surgical site and device this new technology has the potential to revolutionize what were earlier considered as difficult or inoperable cases.

Abstract Introduction: Dental implants are widely accepted as a prosthetic treatment of completely or partially edentulous patients ever since the concept of Osseo integration has been accepted. However, there is a lack of information regarding the knowledge of Dental Implants and especially, the awareness of Peri-implantitis among students. Objective: To evaluate the knowledge and awareness of Dental Implants and Peri-implantitis among students of HCDSH, Hazaribag, Jharkhand. Materials and Method: A cross sectional Survey was conducted among 210 participants which included both Undergraduate and Postgraduate students of HCDSH, Hazaribag, Jharkhand using a self-explanatory questionnaire. The awareness about maintaining the hygiene for dental implants, cost, advantages, disadvantages and also knowledge about periimplantitis was assessed and the results were tabulated. Results: 98.5% of students had heard about dental implants. 64.4% students cited high cost as the biggest disadvantage of a dental implant. Only 54.7% of students had heard about Periimplantitis. 59.8% of students didn’t know the clinical features of Periimplantitis. 68.8% of students had never heard of peri implant mucositis. 68.5% of students were clueless when it came to the clinical feature of Peri implant mucositis and 65.2% of students did not know the sequelae for Peri implant disease. Conclusion: The results of the present survey showed that the majority of the students were largely aware about dental implants but a significant majority of them were unaware about periimplantitis.

Disparity in number of root canals were reported by different authors in permanent teeth but out knowledge is still at infancy about pulpal configuration of primary teeth, so the aim of this case report is to update our clinical proficiency in finding extra canals in maxillary primary second molar to prevent endodontic failure. Ussualy upper primary molars is bounded with 3 canal ie. Mesiobuccal, distobuccal and palatal. Occasionally one can find fourth and fifth canal ie. Second mesiobuccal and second distobuccal canal respectively. So this case report summarises same. Keywords : pulpectomy, endodontic failure, second mesiobuccals canal, second distobuccal canal.

Oral carcinogenesis is known as multifactorial process which engaged plentiful genetic events that transform normal activity of tumor suppressor genes and oncogenes. It is observed that aggregation of genetic alterations is the ground for advancement of a normal cell to cancer cells, which is known as a multi-step carcinogenesis. Because of this event, growth factor production increases as well as increase in total of receptors on cell surface and increased intracellular signal messengers. The present review scrutinize the existing documentation in the literature related to the oral squamous cell carcinoma. English language articles were searched in various databases such as Pubmed, Scopus, Science direct and Google scholar. The keyword used for searching are “oral squamous cell carcinoma”, “Genetics and Oral squamous cell carcinoma”,“Molecular mechanism in oral squamous cell carcinoma”. The present review spotlights on understanding the molecular mechanism and the genetic factors which is responsible for alteration in the cell which leads to oral squamous cell carcinoma.

Apexification is defined as a method to induce a calcific barrier in a root with open apex or the continued apical development of an incompletely formed root in teeth with necrotic pulp tissue. The presented case was of a 26‑year‑old male patient with discoloured tooth associated with external resorption and periapical pathology in relation to the upper front right tooth. Teeth with open apex due to root end resorption pose difficulties during endodontic treatment because of the wide‑open root apex and thin dentin walls. This article describes the procedure of single‑visit apexification using a new calcium silicate‑based material (Biodentine) as an apical barrier along with platelet‑rich fibrin as internal matrix.
