Role of Tumor Markers in Oral Cancer: An Overview.

The oral mucosa represents the first part of the digestive tract and is exposed to various exogenous toxins. Exposure for longer duration can lead to changes that lead to potentially malignant diseases or cancers / Tumors. Eventually these can be diagnosed by routine histopathology, but few of them are difficult to diagnose by this method alone. There arises the role of tumor markers in distinguishing different pathologies is well established. A marker can be described as some inconspicuous object used to distinguish or mark certain things. Mostly tumor markers are proteins and these markers may be detected within exfoliated or distributed cells, or as circulating agents within the peripheral blood or plasma. In the recent years, there is a renewed interest about tumor markers, providing window of opportunity for management of cancer patients by enhancing the efficiency in detection and treatment plan. Recent technological advancement has enabled the examination of many potential markers. This paper focuses on the tumor markers in the head and neck neoplasm.

Analysis of the rate of maturogenesis of a traumatized Cvek’s stage 3 anterior tooth treated with platelet‑rich fibrinas a regenerative tool using three‑dimensional cone‑beam computed tomography: An original case report.

Regenerative endodontic procedures are biologically based procedures which deal with the regeneration of pulp‑like tissue, more idealistically the pulp‑dentin complex. The regeneration of this pulp‑dentin complex in an infected necrotic tooth with an open apex is possible only when the canal is effectively disinfected. Though there are various procedures for treating open apex ranging from Ca(OH) 2 apexification, mineral trioxide aggregate apexification and surgical approach, regeneration of tissues has always taken superior hand over the repair of tissues. The mechanics behind the regenerative endodontic procedures is that despite the tooth being necrotic, some pulp tissue can survive apically which under favorable conditions proliferate to aid in the process of regeneration. In the past 2 decades, an increased understanding of the physiological roles of platelets in wound healing and after tissue injury has led to the idea of using platelets as therapeutic tools in the field regenerative endodontics. In the present case report with an open apex, high sterilization protocol is followed using triple antibiotic paste as intra‑canal medicament, followed which platelet rich fibrin is used as the regenerative material of choice. Over an 18‑month follow‑up period, clinically patient is asymptomatic and radiographically there is complete regression of the periapical lesion and initiation of the root end closure.
