Abstract
Background The excess reactive oxygen species or free radicals reaction leads to oxidative injury to the biological components such as cells and tissues, which would result in the initiation and progression of carcinogenesis. The magnitude of oxidative damage depends primarily on the balance between free radicals (pro-oxidants) and antioxidant system activity. Aim To assess antioxidant status by evaluating the reduced glutathione (GSH) levels in various biological samples of patients with oral squamous cell carcinoma (OSCC) using available literature. Materials and Methods An electronic literature search was carried out in PubMed (MeSH), Science Direct, Scopus and Cross Reference by using specific keywords. Results The systematic electronic search identified 704 articles. After studying the articles' titles and abstracts, 657 articles were excluded for the following reasons; duplicated articles, animal studies, studies of low quality and not relevant to the research question. The remaining 47 articles were selected for full-text assessment. After eliminating the articles that did not match the objectives, the present qualitative synthesis finally included 27 articles for evaluation. The ten studies, which showed coherent data, were included in quantitative analysis. The GSH levels in OSCC groups are significantly decreased (P < 0.001) in plasma and erythrocyte samples compared to healthy controls. Conclusion The selected studies showed significantly lower levels of GSH in various biological samples of OSCC. Hence, future studies are required to validate the expression of GSH as a prognostic biomarker in oral cancer.

Abstract
Objective
This study aimed to evaluate the oxidative stress (OS) marker Malondialdehyde (MDA) in oral submucous fibrosis with available literature.
Materials and Methods
We conducted a literature search electronically in PubMed (MeSH), Science Direct, Scopus, and Google Scholar using specific keywords.
Results
A systematic search in PubMed, Science Direct, and Google Scholar identified 334 articles. Of these, four were duplicate reports, and three were animal studies. After reading the abstracts of the collected articles, 288 articles were excluded for the following reasons: low quality, not relevant to the research question, or did not meet the inclusion criteria. The remaining 46 articles were chosen for full-text assessment. Finally, the present qualitative synthesis included 23 articles for evaluation. The selected studies in MDA analysis in a random-effects model showed higher heterogeneity (Q = 477.636,
p
< 0.001, I

= 95.394%). The standard difference in mean MDA concentration between oral submucous fibrosis (OSMF) and healthy subjects was estimated as 2.73 nmol/mL (95% confidence interval: 2.08–3.38).
Conclusion
The selected studies showed significantly higher MDA levels in various biological samples of patients with OSMF. Therefore, further studies are needed to estimate oxidative stress levels by using different biomarkers in OSMF to direct future therapy.

Abstract
Pleomorphic adenoma is the most common benign salivary gland tumor deriving its name from varied morphological patterns in histopathology. The presence of chondromyxoid stroma in histopathology is characteristic of pleomorphic adenoma. Cellular variants without characteristic chondromyxoid stroma are rare and often pose a diagnostic challenge. We report a case of pleomorphic adenoma involving minor salivary glands of the palate presenting with a predominantly cellular histopathology. Immunohistochemical workup was pivotal in the diagnosis of this challenging case.

Abstract
Aim The aim of this study is to evaluate the efficacy of cheiloscopy (the study of lip prints) and dermatoglyphics (the study of fingerprints) in screening diabetic patients. Materials and Methods The study sample comprised 100 individuals in the age group of 17-60 years, of which fifty were diabetics and fifty controls who reported to the Department of Oral Medicine, Thai Moogambigai Dental College and Hospital. Lip prints were collected and categorized based on the Suzuki and Tsuchihashi system. Fingerprint patterns were obtained and classified according to the Henry's system of classification. Results Type II and IV lip print patterns were predominant in diabetic patients and Type I lip print patterns in controls. The difference was statistically significant. There was no significant difference in fingerprint patterns between the study groups. Gender-wise analysis for lip print and fingerprint patterns did not yield significant results. Conclusion Cheiloscopy is a potential screening tool for type 2 diabetes mellitus. Dermatoglyphics cannot be used as a screening tool in type 2 diabetes mellitus.

Abstract
Background Dental treatment still remains as one of the most anxious visits despite awareness between dentists and patients in building trusting relationships. The fear of dental treatment determines the frequency of treatment availed with long-term implications in oral health maintenance. Aim This study aims to estimate prevalence, extent, and factors influencing dental anxiety in a sample of the adult population visiting a private dental hospital in Chennai, India. Materials and Methods The study sample included 300 consecutive outpatients visiting a private dental hospital in Chennai. Any patient aged 18 and above was considered for the study. A structured custom-made questionnaire composed of ten questions was designed to assess the anxiety levels of dental patients. The level of the patient's anxiety was assessed taking into account various factors that could influence their mental state. This included their age, gender, educational qualification, number/frequency of their dental visits, reason for their visit, past dental experiences, and nature of the dental procedure planned. Enquiries about the related time of anxiety manifestations as well as their preferred anxiety reducing protocols were done as part of the study. Statistics The data analysis was performed using SPSS Version 11.5. Analysis initially was performed with Chi-square test for frequency and reason of visit, with the independent samples t-test used for assessing mean score differences along with Pearson's correlation coefficient. Results The study revealed that dental anxiety has a wide prevalence rate encompassing both genders. Distinctive predominance among females (65.2%) and professionals (66.9%) exhibiting a greater degree of anxiety was identified. Pain and extraction have been cited as duress and anxiety inciting procedures (72.6%). Conclusion This survey has revealed that age, gender, level of education, and procedure along with visit frequency has a direct effect on the patient's state of mind and anxiety.

Abstract
Aim: The aim of the study was to compare the efficacy of an herbal mouthwash containing red ginseng extract with different brands of commercially available chemical mouthwashes. Objective: The objective of the study was to evaluate the effectiveness of herbal mouthwash (Dr. Dental care liquid) in reducing the oral bacterial count and compare it with the efficacy of commercially available mouthwashes such as Rexidine, Listerine and Colgate Plax. Materials and Methods: The study includes sixty normal individuals (aged 18–24 years) who were divided into four groups of 15 individuals each. The participants of each group were given four different mouthwashes (Dr. Dental Care liquid, Colgate Plax, Listerine and Rexidine) and asked to use it twice daily for 5 days. Saliva samples were collected before the use of mouthwash and also after 5 days of using the mouthwashes. Culture and microscopic examination of salivary samples was done, and oral bacterial load present in the saliva samples was counted before and after the mouth rinse use. Results: The results were compared using Wilcoxon sign-rank test. Among the four mouthwashes, the herbal mouthwash, Dr. Dental care liquid exhibited maximum efficacy in reducing the amount of bacteria followed by Colgate Plax, Listerine and Rexidine. Conclusion: The herbal mouthwash, Dr. Dental care liquid, contains red ginseng extract, a herb with immense medicinal values. In this study, the herbal mouth rinse exhibited increased antibacterial action compared with other commercially available chemical mouth rinses. Hence, we conclude that the ginseng-containing herbal mouthwash can be considered as a safe and effective oral hygiene aid.

Abstract
BACKGROUND The practice of medicine in India has undergone considerable change affecting delivery of health in both positive and negative directions. As a result, there was a growing feeling that medical treatment should be made accountable and this led to doctors and dentists becoming subject to the process of law. Patients have become more aware of their right to compensation and as a consequence doctors and dentists should be knowledgeable about the laws that govern them. AIMS AND OBJECTIVES To assess the awareness about Medico legal aspects and Consumer Protection Act [CPA] among Dental professionals. MATERIALS AND METHODS A self-structured validated questionnaire comprising of 20 questions related to medico legal aspects and CPA was designed. A total of 450 dental professionals were surveyed from 4 prime dental institutions in Chennai, India. Of the 450 professionals that were surveyed 150 were MDS faculty, 150 were BDS faculty and 150 were PG students. The data was subjected to SPSS, version 16 and statistically analysed using Chi square test and Fisher's exact test. A- p value less than 0.05 was considered to be statistically significant. RESULTS BDS faculty, MDS faculty and PG students were found to possess similar level of understanding and there was no significant difference between the groups. Knowledge was found to be equal between male and female dentists. The young practitioners were found to be more informed about CPA than the senior practitioners. CONCLUSIONS It was found that most of the participants were aware of relevant Medico legal aspects, but were less aware of CPA. This study emphasises the need for education relevant to Medico legal aspects and CPA for dental professionals.

Abstract
Basal cell adenoma is a rare benign salivary gland neoplasm exhibiting an isomorphic basaloid tumour cell pattern, commonly occurring in the parotid. Membranous variant warrants separate consideration because of its recurrence and rate of malignant transformation. We report a case of membranous type basal cell adenoma occurring in minor salivary gland in a 61-year-old female patient. The histopathological diagnosis was supported by immunohistochemical analysis and serum Carcinoembryonic antigen level.

Abstract
Tongue is a vital internal organ well encased within the oral cavity and protected from the environment. It has unique features which differ from individual to individual and even between identical twins. The color, shape, and surface features are characteristic of every individual, and this serves as a tool for identification. Many modes of biometric systems have come into existence such as fingerprint, iris scan, skin color, signature verification, voice recognition, and face recognition. The search for a new personal identification method secure has led to the use of the lingual impression or the tongue print as a method of biometric authentication. Tongue characteristics exhibit sexual dimorphism thus aiding in the identification of the person. Emerging as a novel biometric tool, tongue prints also hold the promise of a potential forensic tool. This review highlights the uniqueness of tongue prints and its superiority over other biometric identification systems. The various methods of tongue print collection and the classification of tongue features are also elucidated.

Abstract
BACKGROUND AND OBJECTIVES Biometric authentication is an important process for the identification and verification of individuals for security purposes. There are many biometric systems that are currently in use and also being researched. Tongue print is a new biometric authentication tool that is unique and cannot be easily forged because no two tongue prints are similar. The present study aims to evaluate the common morphological features of the tongue and its variations in males and females. The usefulness of alginate impression and dental cast in obtaining the lingual impression was also evaluated. MATERIALS AND METHODS The study sample included twenty participants. The participants were subjected to visual examination following which digital photographs of the dorsal surface of the tongue were taken. Alginate impressions of the tongue were made, and casts were prepared using dental stone. The photographs and the casts were analyzed by two observers separately for the surface morphology including shape, presence or absence of fissures and its pattern of distribution. Three reference points were considered to determine the shape of the tongue. RESULTS The most common morphological feature on the dorsum of the tongue was the presence of central fissures. Multiple vertical fissures were observed in males whereas single vertical fissure was a common finding in females. The fissures were predominantly shallow in males and deep in females. The tongue was predominantly U shaped in males and females. V-shaped tongue was observed in 25% of females. CONCLUSION Tongue prints are useful in biometric authentication. The methodology used in the study is simple, easy and can be adopted by dentists on a regular basis. However, large-scale studies are required to validate the results and also identify other features of the tongue that can be used in forensics and biometric authentication process.

Abstract
Oral cancer refers to the malignancies that occur in the oral cavity, lip and pharynx with 90% of oral cancers being squamous cell carcinomas (OSCC). OSCC has the highest mortality ratio compared to other carcinomas. Although oral cavity is easily accessible, most oral cancers are detected at a later stage leading to lower survival rates. Early detection of OSCC is a key factor in improving the prognosis and survival rate of the patient. Rapid advancement in the field of diagnosis has enabled early diagnosis of many potentially malignant conditions even before its clinical manifestations. One such diagnostic modality that has gained much relevance in the field of molecular biology has been the discovery of salivary biomarkers (DNA, RNA and protein markers). These salivary biomarkers have been shown to play a non-invasive role in the diagnosis and surveillance of oral cancer. The direct contact between the saliva and the oral cancer lesions makes it a most sensitive and specific, screening method in diagnosis, staging and follow-up. This review aims to discuss the effectiveness and the potential of salivary biomarkers as a screening tool in OSCC.

Abstract
INTRODUCTION Oral Submucous Fibrosis (OSMF) is an oral potentially malignant condition caused predominantly by areca nut chewing. Early recognition with accurate staging of the disease and appropriate treatment planning is of utmost importance to prevent the malignant transformation and to improve the quality of life of the patient. Picrosirius red stain is specific for collagen and enhances its birefringence under polarising light producing different colours in different stages of the disease. AIM To compare the clinical and functional staging with histopathologic staging methods used to assess the severity of OSMF and to perform a qualitative analysis of the collagen fibres in various histopathologic stages of OSMF using picrosirius red stain and polarising microscope. MATERIALS AND METHODS It is a retrospective study done on archival samples. The study sample included a total of 30 cases which was divided into two groups. Group I comprised of 20 OSMF samples and Group II comprised of 10 normal tissue samples. Clinical, functional and histopathological staging was performed for all OSMF samples. Comparative analysis between clinical and functional stages with the histopathological staging was done using chi square test. Picrosirius red- stained sections of OSMF were analysed using polarising microscopy to evaluate the qualitative changes in the collagen fibers. STATISTICAL ANALYSIS USED Descriptive data which includes frequency and percentages were calculated for each group. Categorical data were analysed by chi-square test. A p-value of 0.05 or less was considered statistically significant. RESULTS Comparative analysis between clinical and functional stages with the histopathological staging revealed a significant correlation (p < 0.05) between the functional and histopathological stage. Enhanced birefringence of the collagen fibers due to picrosirius red stain yielded characteristic prominent polarising colours in different stages of OSMF. CONCLUSION Comparison of functional staging with histopathologic grading is more reliable in determining the severity of the disease than the clinical staging. Production of characteristic polarising colours by various stages of picrosirius red stained sections of OSMF substantiates the use of picrosirius red stain and polarising microscope as a tool in assessing the severity of this condition thereby aiding in better treatment planning.

Abstract
The morphology of the root and root canal system plays a significant role in the treatment outcome of endodontic procedures. The necessity of clear and high contrast images for tissues like bone and teeth has made the usage of newer imaging techniques inevitable. This is a rare case report wherein, the permanent posterior dentition of both arches was single rooted. While sporadic cases of single rooted teeth have been reported, it is rare for all the premolars and molars to show such variation. This rare clinical observation has been enhanced by Cone Beam Computed Tomography (CBCT), which provides a clear image with added benefits of 3D (Three Dimensional) image reconstruction, low dosage and rapid scan time.

Abstract
Polymorphous low grade adenocarcinoma (PLGA) is a rare, low-grade malignancy of minor salivary glands accounting for 2% of salivary gland tumours. The most common sites are palate (60%), lip, buccal mucosa, alveolar ridge and base of the tongue with retromolar region being very rare (0.5%). It is considered to be a low grade malignancy with indolent nature. Very few cases with metastatic spread to lymph nodes and lung have been reported in literature. This report of PLGA is a rare case presenting in an uncommon location (retromolar area) with suspected lymph node and lung metastases.

Abstract
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 inall 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 mechanismof 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 cornifiedcell envelope, its structure and the alterations that result due to its absence or presence of both the epidermis and the oral mucosa.

Abstract
Hypercementosis is an abnormal thickening of cementum which may be generalized or localized. Localized hypercementosis is usually characterized by nodular enlargement of apical third of root. Hypercementosis in the form of multiple cemental spikes distributed throughout the entire length of root is a very rare finding. In this article, we report such a rare manifestation of localized hypercementosis affecting right maxillary third molar in a 24-year-old male. This finding was an accidental observation following a difficult extraction procedure as the spikes were not evident in the orthopantamogram. It is imperative that every dental practitioner be aware of several presentations of hypercementosis and ensure that such an entity is considered in the differential diagnosis of difficult extraction procedures as an Intraoral Periapical (IOPA) radiograph or even an Orthopantamogram (OPG) could not differentiate the root morphology.

Abstract
Juvenile ossifying fibroma is an uncommon, benign, bone-forming neoplasm with aggressive local growth that is distinguished from other fibro-osseous lesions primarily by its age of onset, clinical presentation and aggressive behavior. Although a benign entity, juvenile ossifying fibroma is known to be locally aggressive and has a high tendency to recur. Two distinctive microscopic patterns have been described: A trabecular variant and a psammomatoid variant. This latter variant is predominantly a craniofacial lesion and occurs rarely in the jaws. We present herein two cases of psammomatoid juvenile ossifying fibroma involving the jaws. The first case was a mandibular lesion in a 31-year-old female whereas the second case presented with maxillary involvement in a 46-year-old female. In addition, the pathology of the lesion was analyzed with confocal laser scanning microscopy.

Abstract
A case of peripheral squamous odontogenic tumor is described in a 60-year-old female who presented with a sessile growth in the right posterior mandible. Radiographic examination revealed no evidence of a central lesion in bone. With the characteristic histopathological picture of benign-appearing islands of squamous epithelium scattered randomly against a background of mature fibrous connective tissue, the tumor was diagnosed as peripheral squamous odontogenic tumor (PSOT). The epithelial islands showed peripheral cuboidal or flattened cells, microcyst formation, individual cell keratinization, and keratin pearl formation.

Abstract
The most common modality of treatment for completely edentulous patients are conventional removable complete dentures. The protocol for fabrication of complete denture would involve a thorough clinical examination and radiographic investigation. As a routine, unless clinical findings suggest presence of remnant tooth structures, or the patient presents himself with symptoms, the radiographic investigations are overlooked. This case report presents one such situation wherein routine radiographic evaluation of a clinically asymptomatic edentulous individual prior to prosthetic rehabilitation revealed the presence of an odontogenic keratocyst of anterior maxilla substantiating the importance of such routine pre-prosthetic radiographic investigations.
