Abstract
Introduction Auricular reconstruction is a technically challenging and aesthetically demanding procedure as the ear has a complex anatomy. Anthropometry aids in achieving aesthetic ear reconstruction. We considered that implication of stereophotogrammetric technology will lead to a better understanding of human ear morphology. Material and methods A cross-sectional study was conducted in our institutional OPD in a tertiary health care centre in the Northern part of India.400 people were chosen based on selection criteria. facial scans were done for 3D pictures using Canfield VECTRA® H2 3D imaging device. Study variables were assessed after marking landmarks on the 3D-generated auricular image of an individual. Discussion This study consisted of 55.5% males and 44.5% females belonging to the age group of 5-25 years (30.3%), 26-40 years (38.8%) and>40 yr (31.0%). Out of 400 cases, the majority had; oval shaped auricle, normally rolled helix, square earlobe; knob shaped tragus. The attached type of earlobe attachment was more in the right auricle (37%) and the partial attachment ear lobe was more in the left side auricle (35.5%). Darwin's tubercle showed more proportion in the case of males. The mean length and width of the auricle & attachment length are higher in males compared to females. Ear Angulation is highest among females. Conclusion Assessment of ear morphology using technologically sound methods like stereophotogrammetry paves the way for a more quick, reliable and easy-to-use method for understanding ear morphology. Precise assessment of ear morphology using stereophotogrammetry helps in providing more cosmetic and acceptable ear restoration.

Abstract
Characterization of the oral microbiota profile through various studies has shown an association between the microbiome and oral cancer; however, stage-specific determinants of dynamic changes in microbial communities of oral cancer remain elusive. Additionally, the influence of the intratumoral microbiota on the intratumoral immune system remains largely unexplored. Therefore, this study aims to stratify microbial abundance in the early-onset and subsequent stages of oral cancer and analyze their influence on clinical-pathological and immunological features. The microbiome composition of tissue biopsy samples was identified using 16S rRNA amplicon sequencing, while intratumoral and systemic immune profiling was done with flow cytometry and immunohistochemistry-based analysis. The bacterial composition differed significantly among precancer, early cancer, and late cancer stages with the enrichment of genera Capnocytophaga, Fusobacterium, and Treponema in the cancer group, while Streptococcus and Rothia were enriched in the precancer group. Late cancer stages were significantly associated with Capnocytophaga with high predicting accuracy, while Fusobacterium was associated with early stages of cancer. A dense intermicrobial and microbiome-immune network was observed in the precancer group. At the cellular level, intratumoral immune cell infiltration of B cells and T cells (CD4+ and CD8+) was observed with enrichment of the effector memory phenotype. Naive and effector subsets of tumor-infiltrating lymphocytes (TILs) and related gene expression were found to be distinctly associated with bacterial communities; most importantly, highly abundant bacterial genera of the tumor microenvironment were either negatively correlated or not associated with the effector lymphocytes, which led to the conclusion that the tumor microenvironment favors an immunosuppressive and nonimmunogenic microbiota. IMPORTANCE The gut microbiome has been explored extensively for its importance in the modulation of systemic inflammation and immune response; in contrast, the intratumoral microbiome is less studied for its influence on immunity in cancer. Given the established correlation between intratumoral lymphocyte infiltration and patient survival in cases of solid tumors, it was pertinent to explore the extrinsic factor influencing immune cell infiltration in the tumor. Modulation of intratumoral microbiota could have a beneficial effect on the antitumor immune response. This study stratifies the microbial profile of oral squamous cell carcinoma starting from precancer to late-stage cancer and provides evidence for their immunomodulatory role in the tumor microenvironment. Our results suggest combining microbiome study with immunological signatures of tumors for their prognostic and diagnostic application.

Abstract
Introduction This study aimed to find an association between psychological burden (in terms of depression, anxiety, and stress) and salivary cortisol among oral cancer (OC) and oral potentially malignant disorder (OPMD) patients at various time frames. Methods In total, 50 patients with OC and OPMD were studied after their informed consent along with 30 healthy controls. Depression, anxiety, and stress scale-21 (DASS-21) was administered and saliva was collected (non-invasively) at different stages including the time of diagnosis, one and three months after intervention (medical or surgical). To avoid diurnal variation, saliva was collected twice (morning and evening). To assess the linear relationship between depression, anxiety, and stress with salivary cortisol, a partial correlation was calculated. Results Comparison of salivary cortisol levels among control, OC, and OPMD groups showed a statistically significant difference in both morning and evening values at different point of time intervals. Higher values of salivary cortisol were observed in OC patients (both morning and evening) in comparison to the OPMD or control group. A positive correlation was discerned between stress and salivary cortisol in both OPMD and OC patients, while no association was found for depression and anxiety domains. Conclusion The measurement of salivary cortisol effectively demonstrates raised stress levels in OPMD as well as OC patients. Therefore, it is recommended to institute stress management interventions in the patients as part of the treatment of OPMD and OC.

Abstract
INTRODUCTION Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (AB PM-JAY) has enabled the Government of India to become a strategic purchaser of health care services from private providers. To generate base cost evidence for evidence-based policymaking the Costing of Health Services in India (CHSI) study was commissioned in 2018 for the price setting of health benefit packages. This paper reports the findings of a process evaluation of the cost data collection in the private hospitals. METHODS The process evaluation of health system costing in private hospitals was an exploratory survey with mixed methods (quantitative and qualitative). We used three approaches-an online survey using a semi-structured questionnaire, in-depth interviews, and a review of monitoring data. The process of data collection was assessed in terms of time taken for different aspects, resources used, level and nature of difficulty encountered, challenges and solutions. RESULTS The mean time taken for data collection in a private hospital was 9.31 (± 1.0) person months including time for obtaining permissions, actual data collection and entry, and addressing queries for data completeness and quality. The longest time was taken to collect data on human resources (30%), while it took the least time for collecting information on building and space (5%). On a scale of 1 (lowest) to 10 (highest) difficulty levels, the data on human resources was the most difficult to collect. This included data on salaries (8), time allocation (5.5) and leaves (5). DISCUSSION Cost data from private hospitals is crucial for mixed health systems. Developing formal mechanisms of cost accounting data and data sharing as pre-requisites for empanelment under a national insurance scheme can significantly ease the process of cost data collection.

Abstract
BACKGROUND In low- and middle-income countries (LMICs), provisioning for surgical care is a public health priority. Ayushman Bharat Pradhan Mantri-Jan Aarogya Yojana (AB PM-JAY) is India's largest national insurance scheme providing free surgical and medical care. In this paper, we present the costs of surgical health benefit packages (HBPs) for secondary care in public district hospitals. METHODS The costs were estimated using mixed (top-down and bottom-up) micro-costing methods. In phase II of the Costing of Health Services in India (CHSI) study, data were collected from a sample of 27 district hospitals from nine states of India. The district hospitals were selected using stratified random sampling based on the district's composite development score. We estimated unit costs for individual services-outpatient (OP) visit, per bed-day in inpatient (IP) and intensive care unit (ICU) stays, and surgical procedures. Together, this was used to estimate the cost of 250 AB PM-JAY HBPs. RESULTS At the current level of utilization, the mean cost per OP consultation varied from US$4.10 to US$2.60 among different surgical specialities. The mean unit cost per IP bed-day ranged from US$13.40 to US$35.60. For the ICU, the mean unit cost per bed-day was US$74. Further, the unit cost of HBPs varied from US$564 for bone tumour excision to US$49 for lid tear repair. CONCLUSIONS Data on the cost of delivering surgical care at the level of district hospitals is of critical value for evidence-based policymaking, price-setting for surgical care and planning to strengthen the availability of high quality and cost-effective surgical care in district hospitals.

Abstract
Objectives To compare and evaluate the modified tragus edge approach (MTEA) with retromandibular approach for surgical access to mid-level or low-level mandibular condylar fractures. Materials and Methods This study comprised of 22 patients with mid-level or low-level condylar fracture. Patients with clinical and radiological evidence of mid-level or low-level condylar fracture are included only in this study. Patients were randomly divided into two groups: group A includes 11 patients, in which modified tragus edge approach was used, and group B includes 11 patients treated with retromandibular approach. Patients were evaluated clinically after first week, second week, fourth week, third month, and sixth month radiographically. Results The mean age of the study subjects in group A was 32.45 ± 8.98 years, while in group B, the mean age was 26.91 ± 5.79 years. Post-operatively, no significant difference was seen in relation to pain, occlusal relationship, mouth opening, and deviation of jaw during opening and closing movements. In terms of post-operative complication, only significant difference found between two groups is post-operative scar visibility, which is higher in retromandibular incision group as compared to MTEA. Conclusion Thus, we can conclude that MTEA provides ease of operation as a good exposure of mandibular mid- or low-level condylar fracture as retromandibular approach but with less visibility of post-operative scar as compared to retromandibular approach.

Abstract
Backgound and Objective: Early chemoprevention in Oral Potentially Malignant Disorders (OPMDs) and Oral Cancer (OC) has been extensively researched in order to mitigate the malignant transformation and progression of the lesion. Many agents have been attempted, but their cost inefficacy and inadequate outcomes posed a major hindrance in their successful adoption. Retinoid Based Therapy (RBT) though a cheap and effective treatment option, could not achieve much clinical usage because of variable responsiveness in clinical outcomes. Such clinical response variability may be attributed to the repression of retinoid receptors by Preferentially Expressed Antigen of Melanoma (PRAME) protein molecule. Therefore, in order to make RBT successful, targeting PRAME by various immunotherapies is an exciting area of research investigation. This review provides an insight into the various immunotherapeutic strategies targeting PRAME and their usefulness in retinoid-resistant OPMD and OC. Method of data collection: An exhaustive internet-based literature search following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was carried out in PUBMED and Google SCHOLAR database using terms 'Anti-PRAME' OR 'PRAME Immunotherapy' OR 'PRAME Vaccines' AND 'Cancer' AND 'Retinoid resistance'. Only articles in the English language with at least 1 citation, published in a journal with impact factor ≥ 1, having relevance to the context and availability of full text were considered. Results: After an initial search, 342 articles were yielded on the basis of inclusion criteria and, by reading the abstract and availability of full text, a total of 124 articles were selected. Further reading the full texts and considering articles from the references of the selected articles, a total of 65 articles were finally included in the review. Conclusion: Our analysis of the literature suggests that PRAME screening in OC and OPMDs prior to RBT should be done. In PRAME positive cases, approaches like PRAME based immunotherapy in the form of Cancer vaccine therapy [Acellular PRAME vaccine, PRAME pulsed Dendritic Cells (DC)]; Adoptive T Cell therapy/T Cell Receptor-T Cell therapy, Antibody therapy/Chimeric Antigen Receptor-T Cell therapy along with Presented antigen modulation Therapies employing histone deacetylase inhibitors and demethylation agents seem plausible. In the future, a combination therapy employing either PRAME vaccines or antibodies or Adoptive T cell Therapy and ATRA could be used in retinoid resistant OC and OPMDs.

Abstract
The last few decades have seen an exponential growth in the development and adoption of novel technologies in medical and surgical training of residents globally. Simulation is an active and innovative teaching method, and can be achieved via physical or digital models. Simulation allows the learners to repeatedly practice without the risk of causing any error in an actual patient and enhance their surgical skills and efficiency. Simulation may also allow the clinical instructor to objectively test the ability of the trainee to carry out the clinical procedure competently and independently prior to trainee's completion of the program. This review aims to explore the role of emerging simulation technologies globally in craniofacial training of students and residents in improving their surgical knowledge and skills. These technologies include 3D printed biomodels, virtual and augmented reality, use of google glass, hololens and haptic feedback, surgical boot camps, serious games and escape games and how they can be implemented in low and middle income countries. Craniofacial surgical training methods will probably go through a sea change in the coming years, with the integration of these new technologies in the surgical curriculum, allowing learning in a safe environment with a virtual patient, through repeated exercise. In future, it may also be used as an assessment tool to perform any specific procedure, without putting the actual patient on risk. Although these new technologies are being enthusiastically welcomed by the young surgeons, they should only be used as an addition to the actual curriculum and not as a replacement to the conventional tools, as the mentor-mentee relationship can never be replaced by any technology.

Abstract
Introduction TMJ ankylosis (TMJa) management by arthroplasty alone fails to address the deformity and the compromised airway. Distraction osteogenesis (DO) can offer a pragmatic solution to TMJa. The aim of the study was to generate evidence towards the role of DO in TMJa, evaluate its efficiency and develop an algorithm for use of DO in TMJa. Material and methods The research question was formulated using the PICOS statement for reporting guidelines in systematic reviews, where the efficiency of DO was evaluated in terms of mouth opening, correction of facial deformity and asymmetry, airway correction, and its long term effects. Results 1130 articles reported DO as a treatment modality for TMJ ankylosis, of which 32 prospective studies, 16 retrospective and 2 RCTs were included in the study. DO was used for mandibular distraction in 45 studies and for simultaneous maxillamandibular distraction in only five studies. An algorithm for use of DO in TMJa was developed. Conclusion Although DO has proven its application in TMJ ankylosis cases, its best use is for correction of obstructive sleep apnoea. Relapse causing loss of posterior ramal height is a concern after transport DO. Prearthroplastic DO appears to best correct mandibular deformity. A maxillomandibular deformity requires simultaneous maxillomandibular distraction. However, a metanalysis is still awaited for effectiveness of DO in TMJ ankylosis.

Abstract
BACKGROUND Histone deacetylases (HDACs) are considered as an essential regulator of cellular proliferation, differentiation, and apoptosis. The HDAC2 enzyme of Class I HDACs plays an important role in tumor progression of human malignancies. OBJECTIVE The aim of the present study was to analyze the HDAC2 gene expression in pre-oral cancer and oral squamous cell carcinoma (OSCC), and its association with clinico-pathological features. METHODS The HDAC2 protein expression was analyzed through the immunohistochemistry and western blot techniques in 82 oral pre-malignant, 90 OSCC, and 16 normal control tissues. qRT-PCR was used to quantify the mRNA fold change in all groups. RESULTS The HDAC2 protein and mRNA levels were significantly higher in OSCC and pre-oral cancer groups compared to the controls. Immunostaining of HDAC2 protein was enhanced in 84.4% of OSCC and 67.1% of pre-cancerous tissue sections (p< 0.01). The mean protein level was analyzed as 1.96 ± 0.44 in oral carcinoma, 1.61 ± 0.39 in pre-cancer and 0.96 ± 0.10 in control tissues. In addition, HDAC2 mean protein level was associated with histological differentiation (OR = 25, p< 0.05) and tumor-node-metastasis (TNM) stages (OR = 6.2, p< 0.05) of OSCC patients. CONCLUSIONS The upregulated HDAC2 gene in pre-cancer and OSCC tissues indicates its crucial role in the transformation of pre-malignant to malignant carcinoma. It could be a potential cancer biomarker of prognosis and targeted therapy in OSCC.

Abstract
Abstract
Objective Locoregional recurrence in oral squamous cell carcinoma (OSCC) is a major concern that leads to metastasis. Its detection at earliest stage is very important to increase the overall survival of the patient. There is no any biomarker for locoregional recurrence in oral squamous cell carcinoma (OSCC). The aim of this study was to find a biomarker for locoregional recurrence in tissue and serum at gene and protein level.
Methods This work studied the expression of protein tyrosine phosphatase nonreceptor type 14 (PTPN-14) and Wilms’ tumor 1 (WT-1) in patients and correlated their expression with locoregional recurrence and survival. Tissue expression was observed in formalin fixed tissue biopsies of 96 OSCC and 32 healthy controls by immunohistochemistry using antibody against PTPN-14 and WT-1 and serum level was estimated by enzyme-linked immunosorbent assay in pre- and post-chemoradiotherapy samples. mRNA expression was determined by using real-time polymerase chain reaction. Patients were followed for 3 years for locoregional recurrence.
Results Expression of PTPN-14 and WT-1 in OSCC was upregulated (aberrant) in tissue and sera in both gene and protein level as compared with healthy controls. Locoregional recurrence was observed in 10 (23.80%) patients and significantly associated with PTPN-14 (p < 0.047) and WT-1 expression (p < 0.031).
Conclusion PTPN-14 and WT-1 may be used as biomarker to identify patients for higher risk of locoregional recurrence. This study drove molecular aspect and phenotypic level to derive new emergent strategies in future for recurrent OSCC.

Abstract
AIM AND OBJECTIVES The aim of this study was to analyse the outcomes of orbital floor reconstruction with two types of orbital implants and assess patients' quality of life. MATERIAL AND METHODS 39 sequential patients with clinical and radiological evidence of orbital floor fracture, presenting diplopia, enophthalmos, paraesthesia or a post traumatic residual orbital deformity were included in this study and randomised for orbital floor reconstruction using porous polyethylene sheet (Biopore™) or preshaped titanium mesh on a 3D model. Their pre and postoperative quality of life were compared. Success rate was assessed and scored with a minimum of zero (none) and a maximum of ten (excellent) for improvement in the signs of diplopia, enophthalmos, hypoglobus, paraesthesia and aesthetics. RESULTS Both QOL scores and Success score was greater in cases which reconstruction of orbital floor was performed with preshaped titanium mesh as compared to those with Biopore™. CONCLUSION Preshaped titanium mesh shows better results than reconstruction with Biopore™. However a large sample size and a long term follow up is needed for generating the best evidence. Quality of life extensively improves after orbital floor reconstruction motivating the patients desire to live.

Abstract
Purpose The aim of this article was to systematically review the available literature on patient specific total temporomandibular joint total joint replacement (PS-TMJR) implants for their biomaterial, designs, fabrication techniques and their outcomes. Methods A literature review was conducted using PubMed, and science direct databases using the key words three-dimensional printing, 3D printing, CAD CAM, computer aided designing, computer aided manufacturing, additive technology, custom made implants, patient specific implants in combination with Temporomandibular joint, TMJ surgery. Results The search revealed 2760 articles, of which 374 were in English and discussed TMJ reconstruction. Further filtering shortlisted 74 articles that discussed PS-TMJR. Duplicates were removed and additional added from article references. 39 articles describing biomaterial, designing and fabrication of PS-TMJR implants and their outcomes were selected for analysis. Conclusions Although PS-TMJR implants allow a better anatomical fit, improved fixation, and safeguard various structures such as the inferior alveolar nerve, they vary in designs, material and fabrication techniques. However, PS-TMJR printed with SLM and EBM technologies have yet to be compared with the conventional ones in terms of mechanical strength, and clinical outcome. With emerging bioprinting technologies, even newer biomaterials should be considered for 3D printing of PS-TMJR devices designed to achieve harmony in function between the joint device, bone and masticatory muscles.

Abstract
Nanotechnology-based miniaturized devices have been a breakthrough in the pre-clinical and clinical research areas, e.g. drug delivery, personalized medicine. They have revolutionized the discovery and development of biomarker-based diagnostic devices for detection of various diseases such as tuberculosis, malaria and cancer. Nanomaterials (NMs) hold tremendous diagnostic potential due to their high surface-to-volume ratio and quantum confinement phenomenon, improving the detection limit of clinically relevant biomolecules in bio-fluids. Thus, they are helpful in the translation of bench-on platform to point-of-care (POC) screening device. The nanomaterial-based biosensor fabrication technology has also simplified and improved oral cancer (OC) or oral squamous cell carcinomas (OSCC) diagnosis. The fabrication of nano-bio sensors involves application specific modifications of NMs. The unique properties functionalized NMs have augmented their application on the nano-biosensing platform for the detection of clinically relevant biomolecules in bio-fluids. Therefore, this article summarizes the recent advancements in the process of fabrication of nano-biosensors for detection of OC.

Abstract
OBJECTIVES The digital technologies, in recent years, have integrated with temporomandibular joint reconstruction surgeries (TRS). Therefore, a systematic study was conducted to assess the impact of digital technologies in TRS. Besides, a brief comparison between the CAD/CAM and 3D printing (3DP) technologies is presented. MATERIALS & METHODS We searched in PubMed, ProQuest and Science direct using PRISMA guidelines. Population = Patients undergoing TRS, Intervention=CAD/CAM or 3DP, Comparison= conventional TRS (cTRS) vs technology integrated TRS (tiTRS), Outcome= Advantages/disadvantages of technology and Subjective/objective symptoms, Study design= Type of study. The quality of observational study was assessed using ROBINS-1 Assessment tool. RESULTS Out of 632 articles, 30 articles for CAD/CAM and 3DP were included in the study. A majority of TRS were done for ankylosis (new or re-entry), earlier failed surgery, osteoarthritis and neoplastic cases. The articles were divided into two groups. Group I: CAD/CAM(n = 16), Group II: 3DP (n = 14). DISCUSSION tiTRS had definite advantages over cTRS with lesser surgery time, defined osteotomies, précised implant fitting and better final result outcome however, evidence for tiTRS in long-term follow-up is inconclusive. The cost, time, infrastructure and ethical/regulatory issues are the downsides of assisted surgeries. It was observed that 3DP technology is versatile and its adaptation in the fabrication of customized implants has outpaced CAD/CAM technology. However, literature data is feeble qualitatively and quantitatively. CONCLUSION The TRS has leveraged the flexibility and precision of assisted surgeries. In future, tiTRS could successfully replace cTRS, provided that shortcomings should be dealt so that the technology can benefit the masses.

Abstract
Objective The purpose of this study was to evaluate the quality of life among the Oral Potentially Malignant Disorder (OPMD) patients during diagnosis, at one month and 3 months after intervention (surgical or conservative). Methods The University of Washington Quality of Life version (4UWQOL v4) and World Health Organization (WHO-BREF) were repeatedly administered on 54 OPMD patients. Results The results of Friedman's ANOVA showed a statistically significant change in the mean scores for pain, activity, speech, shoulder, taste, saliva, mood, and anxiety domains of UWQOL with time, (p-value <0.05); while physical health, social relationships, environment domains of WHO- BREF have shown significant changes in their respective mean scores. Conclusion The assessment of Quality of Life (QOL) should routinely be done by the clinicians. If the clinicians start considering the QOL as the primary outcome of a treatment protocol, it will enhance patients' identity, well-being, and personality.

Abstract
OBJECTIVE The aim of our study was to evaluate the success of distraction osteogenesis in temporomandibular joint (TMJ) ankylosis patients with facial deformities at our maxillofacial unit; assess the psychosocial and well-being outcomes of distraction osteogenesis and its impact on oral health; and discriminate the differences in quality of life (QoL) with application of external or internal devices, unilateral or bilateral, linear or multivector, and maxillomandibular or mandibular distraction. STUDY DESIGN QoL and the Oral Health Impact Profile (OHIP) were prospectively studied in 42 consecutive patients with facial deformities, planned for maxillofacial distraction osteogenesis, using 2 validated questionnaires, the Orthognathic Quality of Life Questionnaire and OHIP-14. Patients who had undergone any previous surgeries were excluded. RESULTS Among these patients, 16 were female, 26 male; mean age was 14.98 ± 4.88 years, and all had prearthroplastic distraction. The shortening in the mandible was in the proportion 29:01:12 in the body, ramus, and ramus-body, respectively. Mean QoL scores before and after distraction were 68.52 ± 9.50 and 26.62 ± 3.51; and mean OHIP scores before and after distraction were 33.88 ± 6.26 and 15.36 ± 2.54, a highly significant difference (P < .001) suggesting improvement. Significant improvement was identified on all QoL and OHIP questions after distraction (P < .01). The postdistraction overall mean QoL score among patients with extraoral or intraoral distractor did not have a significant difference (P = .32), but facial appearance in the bilateral distraction group; jaw function and overall well-being in the multivector distraction group; and facial appearance, jaw function, and overall well-being in maxillomandibular distraction group had significant improvements (P < .05). CONCLUSIONS Distraction osteogenesis considerably improves oral health and health-related QoL in patients with TMJ ankylosis with facial deformities. The use of an external or internal distractor did not make any difference in the QoL; however, bilateral distraction, multivector distraction, and maxillomandibular distraction resulted in better QoL outcomes.

Abstract
Introduction Finite element analysis (FEA) is a method to mimic the biomechanical behaviour of an object under various loading scenarios, and may be used during virtual planning of the TMJ prosthesis. Here we present an interesting case report where FEA was done to biomechanically evaluate patient specific total joint replacement prosthesis for bilateral TMJ replacement. Case report A 22 year old young girl visited our outpatient clinic with a chief complaint of retruded chin and limited mouth opening for the last 15 years. After clinical and radiographic examination, her corrective surgery was virtually planned on Mimics software. The Implants were studied under simulated loading scenarios in ANSYS to understand the structural integrity of the implant for different loading conditions. Results Maximum Von-Mises Stress on Condylar component is 151.9 MPa and Maximum Von-Mises Stress on Fossa component is 0.377 MPa. The minimum safety factor of the fossa component was about 15, which is safe enough to complete 100 million cycles. The maximum von-mises stress were detected at the screw holes in the condylar components of the implant. The screw holes were therefore the areas prone to highest chance of failure in the design. Conclusion We conclude that FEA based biomechanical analysis is important prerequisite during customized reconstruction of TMJ. In today's scenario of patient specific TMJ reconstruction, FEA based designing and planning of stress distribution along the bone and calculation of maximum strain in the prosthesis, further aids in the proper designing of this implant and enhances the post-operative clinical results.

Abstract
BACKGROUND Considering the structural and functional complexity of the craniofacial tissues, 3D bioprinting can be a valuable tool to design and create functional 3D tissues or organs in situ for in vivo applications. This review aims to explore the various aspects of this emerging 3D bioprinting technology and its application in the craniofacial bone or cartilage regeneration. METHOD Electronic database searches were undertaken on pubmed, google scholar, medline, embase, and science direct for english language literature, published for 3D bioprinting in craniofacial regeneration. The search items used were 'craniofacial regeneration' OR 'jaw regeneration' OR 'maxillofacial regeneration' AND '3D bioprinting' OR 'three dimensional bioprinting' OR 'Additive manufacturing' OR 'rapid prototyping' OR 'patient specific bioprinting'. Reviews and duplicates were excluded. RESULTS Search with above described criteria yielded 476 articles, which reduced to 108 after excluding reviews. Further screening of individual articles led to 77 articles to which 9 additional articles were included from references, and 18 duplicate articles were excluded. Finally we were left with 68 articles to be included in the review. CONCLUSION Craniofacial tissue and organ regeneration has been reported a success using bioink with different biomaterial and incorporated stem cells in 3D bioprinters. Though several attempts have been made to fabricate craniofacial bone and cartilage, the strive to achieve desired outcome still continues.

Abstract
Highly keratinized oral squamous cell carcinoma (OSCC) exhibits an improved response to treatment and prognosis compared with weakly keratinized OSCC. Therefore, we aimed to develop gene transcript signature and to identify novel full-length isoforms, fusion transcript and non-coding RNA to differentiate well-differentiated (WD) with Moderately Differentiated (MD)/Poorly Differentiated (PD)/WD-lymphadenopathy OSCC through, HTA, Isoform sequencing, and NanoString. Additionally, specific copy number gain and loss were also identify in WD keratinized OSCC through Oncoscan array and validated through Real-time PCR in histopathologically characterized FFPE-WD keratinized OSCC. Three-hundred-thirty-eight (338) differentially expressed full-length (FL) transcript isoforms (317 upregulated and 21 down-regulated in OSCC) were identified through Isoform Sequencing using the PacBio platform. Thirty-four (34) highly upregulated differentially expressed transcripts from IsoSeq data were also correlated with HTA2.0 and validated in 42 OSCC samples. We were able to identify 18 differentially expressed transcripts, 12 fusion transcripts, and two long noncoding RNAs. These transcripts were involved in increased cell proliferation, dysregulated metabolic reprogramming, oxidative stress, and immune system markers with enhanced immune rearrangements, suggesting a cancerous nature. However, an increase in proteasomal activity and hemidesmosome proteins suggested an improved prognosis and tumor cell stability in keratinized OSCC and helped to characterize WD with MD/PD/WD with lymphadenopathy OSCC. Additionally, novel isoforms of IL37, NAA10, UCHL3, SPAG7, and RAB24 were identified while in silico functionally validated SPAG7 represented the premalignant phenotype of keratinized (K4) OSCC. Most importantly we found copy number gain and overexpression of EGFR suggest that TKIs may also be used as therapeutics in WD-OSCCs.

Abstract
Bcl-2 (B cell Lymphoma -2) family comprises of both anti-apoptotic and pro-apoptotic proteins whose altered expression or change in ratio inhibits apoptosis, and promotes tumor progression. The aim of this study is to assess the usefulness of Bcl-2 in distinguishing dysplastic or malignant epithelium from non-dysplastic or normal epithelium to aid in prediction of malignant transformation potential. Material and method Study group comprised of 30 cases of clinically diagnosed leukoplakia (OPMD), 15 cases of Oral Squamous Cell Carcinoma (OSCC) and 5 normal tissue samples. The labeling index of Bcl-2 was analyzed in immunohistochemically stained sections. Different statistical tools were used to analyze the data and to compare Bcl-2 expression qualitatively and quantitatively among all the groups. Results An increasing trend of Bcl-2 immunoexpression was observed from normal epithelium to non-dysplastic and from non-dysplastic to dysplastic lesions. In OSCC, the peripheral cells in the differentiating epithelial islands (within the connective tissue) showed Bcl-2 immuno-reactivity, which gradually decreased towards the center. In contrast, intense and diffuse Bcl-2 immuno-reactivity was seen in poorly differentiated carcinoma. But the overall Bcl-2 positivity was less in OSCC as compared to dysplastic lesions. Conclusion Increased expression of Bcl-2 oncoprotein in sequentially progressing epithelial dysplasia and down-regulation in differentiating carcinoma (well and moderately differentiating OSCC) unveils the clinical relevance of Bcl-2 in early stages of OSCC tumorigenesis. The heterogenous expression of Bcl-2 in carcinoma with different grades of differentiation renders them unable to be used as an independent tool for predicting transition from oral pre-malignancy to malignancy.

Abstract
Oral cancers needs relentless research due to high mortality and morbidity associated with it. Despite of the comparable ease in accessibility to these sites, more than 2/3rd cases are diagnosed in advanced stages. Molecular/genetic studies augment clinical assessment, classification and prediction of malignant potential of oral lesions, thereby reducing its incidence and increasing the scope for early diagnosis and treatment of oral cancers. Herein we aim to review the role of apoptosis and genes associated with it in oral cancer development in order to aid in early diagnosis, prediction of malignant potential and evaluation of possible treatment targets in oral cancer. An internet-based search was done with key words apoptosis, genes, mutations, targets and analysis to extract 72 articles after considering inclusion and exclusion criteria. The knowledge of genetics and genomics of oral cancer is of utmost need in order to stop the rising prevalence of oral cancer. Translational approach and interventions at the early stage of oral cancer, targeted destruction of cancerous cells by silencing or promoting involved genes should be the ideal intervention.

Abstract
Osteogenic differentiation of Mesenchymal stem cells (MSCs) on scaffold is crucial for bone tissue engineering. Alkaline phosphatase (ALP) assay is an important method of assessing osteogenesis. Here, a very simple and innovative procedure is being described for quantification of osteogenic differentiation of MSCs in presence of scaffold using ALP assay. Different concentrations of the scaffold particles with the same number of MSCs were assayed for alkaline phosphatase activity using p-NPP as substrate for ALP activity. G-bone scaffold was used in concentrations of 5, 20, 60 and 100 mg/ml and same number of MSCs were seeded. Any scaffold which can be grind and weighed may be used. It was found that100 mg/ml G-bone graft was most useful for promoting osteogenesis and addition of growth factors further promoted. So, we were able to ascertain the concentration of scaffold which promotes osteogenesis the most.

Abstract
The present case-control study aimed to investigate the role of interaction of glutathione-s-transferase (GST) genotypes with environmental risk factors in determining susceptibility to head and neck squamous cell carcinoma (HNSCC) involving 1,250 cases and equal number of healthy controls. An increase in the risk of HNSCC and its subsites (larynx, pharynx, and oral cavity) was observed among the cases with null genotypes of GSTM1 (odds ratio [OR] = 1.87) or GSTT1 (OR = 1.39) while reduced risk (OR = 0.81) was observed the cases with variant genotype of GSTP1. Tobacco use in the form of smoking or chewing interacted multiplicatively with GSTM1 or GSTT1 to increase the risk several folds (3-10 folds) in HNSCC and its subsites. Alcohol use also increased the risk (2-3 folds) to HNSCC and its subsites in cases with null or variant genotypes of GSTs, though this risk was of lesser magnitude when compared to the tobacco users. A synergistic effect of both, tobacco smoking and alcohol drinking, led to several folds (25-folds) increased risk to HNSCC among the cases with null genotype of GSTM1 and GSTT1 when compared to nonsmokers and nondrinkers with wild genotype of GSTM1 and GSTT1 in controls. Furthermore, cases with variant genotypes of GSTP1 (Val/Val) showed superior treatment response with improved survival rate and lower risk of death when compared to the patients with wild type genotype (Ile/Ile). The data suggest that though polymorphism in GSTs may be a modest risk factor for determining HNSCC risk, gene-environment interactions significantly modify the susceptibility to HNSCC by several folds.

Abstract
Introduction The tobacco use and the dietary intake/levels of vitamin C and E, and the trace elements, iron, copper, zinc, and selenium are interrelated with the development of oral precancer. These micronutrients are necessary for maintaining good oral health. Aims To estimate the nutritional status, vitamin E, C and micronutrient level of zinc, iron, copper, and selenium, and basic vitals in all study groups. Material Method The study sample is comprised of 384 subjects. There were three study groups, and in each study group, there were 128 subjects. Group A was tobacco users without oral precancer/dysplasia. Group B was tobacco users with oral precancer (H/P confirmed). Group C was healthy individuals with no history of tobacco or areca nut use and oral precancer. Data have been collected using a standard structured predesigned questionnaire for evaluation of the nutrition level of the subject; 5 mL blood has been collected for estimation of micronutrients; and basic vitals such as pulse rate and blood pressure have been examined using the digital machine. Questionnaire data will also be entered in the worksheet for the purpose of analysis. The analysis will be performed using the commercially available Statistical Package SPSS. Result The serum level of zinc, iron, selenium, vitamin E and C was decreasing in Groups A and B, i.e., users with precancer and users without precancer as compared to Group C, i.e., controls. But serum copper level was increasing in Groups A and B, i.e., users with precancer and users without precancer, and the level was found to be decreased in Group C, i.e., controls. Later on, in the present study, basic vitals such as blood pressure and pulse rate of all the study subjects in all the three groups were clinically examined. No significant differences were found in blood pressure, pulse rate (radial pulse), and height in all groups. But the weight was slightly higher in Groups A and B as compared to Group C. Discussion Diet plays an aggressive role in the development of oral precancer. The deficiency of certain micro nutrients may lead to disease progression. We can say that a healthy diet comprising of vegetarian and plain food may lead to solving issues of oral health. Conclusion The above-highlighted text shows that micronutrients play dominant role in maintenance of oral health and its deficiency may result in the growth of oral precancer. So involving diet rich in zinc, iron, selenium, vitamin E and C may help in maintaining healthy nation.

Abstract
Aims The purpose of this article was to study and devise a classification of fracture patterns of the mandibular ramus to facilitate management. Methods Mandibular ramus fracture demographics in literature were reviewed along with evaluation of the patients diagnosed with mandibular ramus fractures who had reported to the emergency/outpatient clinic of our Institute in the last 5 years. Epidemiology of these ramus fractures was studied, and these ramus fractures were categorized into repetitive patterns on the basis of radiological observations in an effort to achieve a simplified classification. Results A total of 1372 trauma patients were diagnosed with mandibular fractures, of which an incidence of 2.4% was recorded for ramus fractures. These were predominantly in males and mainly due to road traffic accidents commonly in people driving two-wheeler vehicles (64%). Ramus fractures seldom occur in isolation. Five predictable fracture patterns were observed and accordingly classified as types I to V. Type I was the most common and type IV the least. Open reduction was done in 45.5% patients with non-compression plating systems. Satisfactory aesthetic and functional outcomes were achieved in all patients. Conclusion The mandibular ramus fractures although rare need to be well understood and demarcated. The classification highlights the importance of this mandibular buttress and focuses on the importance of its technically and anatomically more complicated fracture treatment. Future studies are needed to compare the modalities of management.

Abstract
Bone tissue engineering using polymer based scaffolds have been studied a lot in last decades. Considering the qualities of all the polymers desired to be used as scaffolds, Polycaprolactone (PCL) polyester apart from being biocompatible and biodegradable qualifies to an appreciable level due its easy availability, cost efficacy and suitability for modification. Its adjustable physio-chemical state, biological properties and mechanical strength renders it to withstand physical, chemical and mechanical, insults without significant loss of its properties. This review aims to critically analyse the efficacy of PCL as a biomaterial for bone scaffolds.

Abstract
Aim: The present study focuses on the prevalence of tobacco use and aims to determine various sociocultural aspects of tobacco use in Indian population. Materials and Methods: The study sample comprised 384 participants. There were three study groups, and in each study group, there were 128 participants. Group A was tobacco users without oral precancer, Group B was tobacco users with oral precancer, and Group C was healthy individuals with no history of tobacco or areca nut use and oral precancer. Both male and female adults in the age group of 18 years and above visiting the Outpatient Department of Oral and Maxillofacial Surgery at King George's Medical University were recruited for the study. The study participants were explained in detail about the study, and informed consent was obtained through them. Data have been collected using a standard structured predesigned questionnaire. The questionnaire consisted of the details of the demographic profile of the study participants, details of tobacco use, and the major social and cultural reasons which motivated them to consume tobacco. Data were extracted from the case sheet, and the data were entered into a worksheet for the purpose of analysis. The analysis was performed using the commercially available Statistical Package SPSS. Conclusion: The rate of tobacco prevalence is very high among the Indian population, and a number of social and cultural factors are responsible for its use. To curb this problem, more studies could be done to find the causes responsible for its use.

Abstract
Background and objectives Dental fear among adolescents may be associated with parenting style, however, there is little research of its effect in the Indian population. Hence, this study was planned to explore the association between dental fear and parental authority and to analyze the most common parenting style practiced in India. Methods 43 participants in the age group of 12-18 years were enrolled in the study after their parents informed consent. Data regarding: demographic details, number of visits to dental clinic, Modified version of Child Fear Survey Schedule-Dental Subscale, and Parental Authority Questionnaire scores were collected and analyzed. Results Dental fear score was most in males who had visited the dental clinic less than 5 times (53.4 ± 11.04). The dental fear reduced significantly with increase in number of visits in dental clinic. The dental fear was significantly more in 12-15 years of age group than in 16-18 years age group.There was a direct co relation of dental fear with authoritarian parents and inversely related with authoritative and permissive parenting. Parenting style showed that most of the mothers were authoritarian (39.53%), authoritative (32.56%) and the least were permissive (23.26%) types. Similarly, fathers were authoritarian (36.58%), Authoritative (26.82%) and Permissive (17.07%). Conclusion Authoritarian parenting style is the most prevalent parenting style witnessed amongst both mothers and fathers in the Indian culture. High dental fear in children is directly associated with authoritarian parents while inversely with authoritative and permissive parenting style. The study recommends permissive parenting style for mothers and authoritative for fathers to reduce dental fear among their children.

Abstract
Context Bone morphogenetic proteins (BMP) are multifunctional molecules of transforming growth factor-β superfamily that induces the differentiation of fibroblasts into osteoblasts to form bone. Aims This study was undertaken to evaluate the effects of recombinant human BMP-7 (rhBMP-7) in bone healing of small maxillofacial bone defects and assess the serum levels of osteopontin (OPN) and receptor activator of nuclear factor kappa-B ligand (RANKL) biomarkers for bone remodeling. Materials and Methods Twenty patients with small maxillofacial bony defects were enrolled in this study and randomly allocated to two groups; wherein after apicoectomy of the involved teeth, the control group had defect filled with collagen sponge only while the experimental group had rhBMP-7 impregnated collagen sponge placed in the defect. Results The clinical parameters showed no significant difference between the two groups (P > 0.05). The radiographic parameters showed a significantly slower rate of reduction in bone defect volume (P < 0.01) in control group than the experimental group when followed at 2, 4 and 24 postoperative weeks. RANKL and OPN serum levels showed no significant changes in pre- and post-operative stage. Conclusion This study confirms that rhBMP-7 in collagen definitely accelerates bone healing in maxillofacial bone defects and minimizes postoperative complications. RANKL and OPN biomarkers in serum may not show bone remodeling, hence tissue samples may be used to assess their levels.

Abstract
Background and Objectives The aim of the present study was to carefully translate and psychometrically validate the depression, anxiety, and stress scale-21 (DASS-21) in Hindi language for Hindi-speaking head and neck cancer (HNC) and oral potentially malignant disorder (OPMD) patients. Materials and Methods One hundred and sixty-seven HNC and OPMD patients were recruited for this study comprising of 111 oral cancer and 56 OPMD patients. According to internationally accepted guidelines, forward and backward translation procedures were performed, to develop a culturally acceptable version of DASS-21. Validated Hindi version of hospital anxiety and depression scale (HADS) questionnaire was used to compare the scores. Internal consistency for construct validity of the DASS-21 was assessed. Related data and the patients' demographics details were recorded. Factor analysis using varimax rotation was also carried out. Results The Cronbach's alpha values were 0.998, 0.990, and 0.994, respectively, for depression, anxiety, and stress domains, which was comparable to other studies and indicated a strong internal consistency and good construct validity. Factor and varimax analysis revealed items to be well suited to their respective domains. A statistically significant strong correlation was reflected with HADS Hindi questionnaire; Spearman's rank correlation values observed were 0.80 and 0.83 for depression and anxiety, respectively. Interpretation and Conclusions Hindi version of the DASS-21 questionnaire appears to be culturally appropriate, reliable, and psychometrically valid tool for evaluation of the psychological burden (depression, anxiety, and stress) in Hindi-speaking HNC and OPMD patients.

Abstract
Purpose: To develop peripheral blood mRNA expression profiles of drug metabolizing enzymes (DMEs) as a surrogate to monitor tobacco induced head and neck squamous cell carcinoma (HNSCC), attempts were made to investigate (i) similarities in alterations with the cancer marker genes in biopsy samples and (ii) if alterations similar to that seen in biopsy samples are reflected in peripheral blood. Methods: Total RNA from eight soft gingival tissues and eight biopsy samples of HNSCC patients and total DNA and RNA from blood of healthy controls (n = 150) and HNSCC patients (n = 150) was processed for expression and genotyping studies. Blood from patients receiving chemo-radiotherapy was processed for follow-up study. Results: qRT-PCR revealed significant increase in mRNA expression of DMEs in biopsy and blood samples of HNSCC patients when compared to controls. Similar alterations were observed in cancer marker genes in these samples. Patients with variant genotypes of DMEs showed greater magnitude of alterations in mRNA expression when compared to wild type controls. Responders of chemo-radiotherapy showed significant decline in induction of mRNA expression of DMEs and cancer marker genes Conclusions: The data suggest that peripheral blood expression profiles could be used to monitor tobacco-induced HNSCC as well as the treatment response.

Abstract
TaqMan Low-Density Array (TLDA) based Real-Time PCR (RT-PCR) of selected genes showed increased expression of polycyclic aromatic hydrocarbons (PAHs) metabolizing cytochrome P450s (CYPs), glutathione S-transferases (GSTs) and associated transcription factors in biopsy and peripheral blood samples isolated from head and neck squamous cell carcinoma (HNSCC) patients when compared to the controls. The genes involved in DNA repair, signal transduction pathway, EMT pathway, apoptosis, and cell adhesion/motility were found to be altered in both peripheral blood and biopsy samples of HNSCC patients. Transcription profiles in blood isolated from auto/taxi drivers, with pre-neoplastic lesions and history of tobacco use, also showed similar alterations. The present TLDA data thus demonstrates that low-density array of selected genes in peripheral blood has the potential to be used as a surrogate for providing insight into cancer progression pathways and possibly as an early biomarker for monitoring tobacco induced HNSCC.

Abstract
Abstract
Large and increasing public-databases of oral squamous cell carcinoma (OSCC) transcriptome sequencing data has been generated through next-generation which has limitation for novel full-length transcript isoforms. Hence, our objective was to identify differential specific OSCC-related novel full length transcript isoforms, long noncoding RNA and fusion genes compared to non-matched oral-cavity control samples through PacBio-RSII platform. The OSCC, patients from different anatomical sites (gingivobuccal region, retro-molar trigone and lower gum) were processed through human transcriptome array 2.0 (HTA2.0). Heatmap generated expression patterns showed two distinct subgroups against control. Both tumor and control samples were individually run on Oncoscan array. On aggregate analysis significant copy number gain of Ch 7p11.2 EGFR gene; and Ch11q13.3-13.4 (FGF19, FGF4, FGF3, LOC101928443, ANO1-AS2, ANO1, FADD, MIR548K, PPFIA1, CTTN, SHANK2) were identified. Based on HTA2.0 and Oncoscan array we pooled six oral cancer and three oral control samples for Isoseq analysis. Differentially expressed full length transcripts between OC and OT were generated through GFOLD and were processed through Reactome Pathway. On considering more than 20 transcript-entities, Metabolism of RNA (22), Developmental Biology (25), Cytokine Signaling (25), Innate Immune System (25), Metabolism of proteins (31), Immune System (35), Metabolism (29), and Signal Transduction (21) pathways were identified. Differential regulation was also validated through HTA2.0. The identified high quality full length transcripts were annotated and classified through Blast2Go in different sub-group under Biological-Process, Cellular-Process and Molecular-function in Level 2. Out of these most highly up-regulated were Type I-Keratins (KRT)-KRT17, -KRT16, -KRT14 and Type-II keratins-KRT6A and -KRT6B showing involvement of formation of cornified envelope, Keratinization, Cell-cell communication, Type I hemi-desmosome assembly and developmental biology pathways. Long non-coding RNA-NMD candidates ARL2-SNX15, RAB4B-EGLN2, SENP3-EIF4A1 and fusion genes-ACTA2–ACTB, ACTB–ACTC1, ACTB–ACTG2, CALML3–CALM3, CKM–CKB, ENO1–ENO3, IGKV1-27–IGKV3-15, IGKV4-1–IGKJ1, IGKV4-1–IGKJ2, IGKV4-1–IGKJ3, IGKV4-1–IGKJ4, KRT6B–KRT6A were also differentially expressed. Additionally, 457 novel full length transcript isoforms including 289 from OC and 168 from OT datasets were identified. Hence, differentially regulated-KRT17, KRT16, KRT14, KRT6A, KRT 6B; long non-coding RNA and identified fusion genes and full length novel transcript isofoms may be the characteristic of these tumors after validation in histo-pathologically characterized FFPE-Keratinized OSCC and may also prove as early detection marker for Keratinized OSCC if identified in pre-neoplastic conditions.

Abstract
Radioresistance is one of the main determinants of treatment outcome in oral squamous cell carcinoma (OSCC), but its prediction is difficult. Several authors aimed to establish radioresistant OSCC cell lines to identify genes with altered expression in response to radioresistance. The development of OSCC is a multistep carcinogenic process that includes activation of several oncogenes and inactivation of tumour suppressor genes. TGM-3 is a tumour suppressor gene and contributes to carcinogenesis process. The aim of this study was to estimate serum and tissue expression of TGM-3 and its correlation with clinico-pathological factors and overall survival in patients of OSCC undergoing chemo-radiotherapy. Tissue expression was observed in formalin fixed tissue biopsies of 96 cases of OSCC and 32 healthy controls were subjected to immunohistochemistry (IHC) by using antibody against TGM-3 and serum level was estimated by ELISA method. mRNA expression was determined by using Real-Time PCR. Patients were followed for 2 year for chemo radiotherapy response. In OSCC, 76.70% cases and in controls 90.62% were positive for TGM-3 IHC expression. TGM-3 expression was cytoplasmic and nuclear staining expressed in keratinized layer, stratum granulosum and stratum spinosum in controls and tumour cells. Mean serum TGM-3 in pre chemo-radiotherapy OSCC cases were 1304.83±573.55, post chemo-radiotherapy samples were 1530.64±669.33 and controls were 1869.16±1377.36, but difference was significant in pre chemo-radiotherapy samples as compared to controls (p<0.018). This finding was also confirmed by real- time PCR analysis in which down regulation (-7.92 fold change) of TGM-3 in OSCC as compared to controls. TGM-3 expression was significantly associated with response to chemo-radiotherapy treatment (p<0.007) and overall survival (p<0.015). Patents having higher level of TGM-3 expression have good response to chemo-radiotherapy and also have better overall survival. TGM-3 may serve as a candidate biomarker for responsiveness to chemo-radiotherapy treatment in OSCC patients.

Abstract
Background: The c-Fos nuclear protein dimerizes with Jun family proteins to form the transcription factor AP-1 complex which participates in signal transduction and regulation of normal cellular processes. In tumorigenesis, c-Fos promotes invasive growth through down-regulation of tumor suppressor genes but its role in oral carcinogenesis is not clear. Objectives: This study concerned c-fos gene expression in normal and malignant tissues of the oral cavity, with attention to associations between expression status and clinico-pathological profiles of OSCC patients. Method: A total of 65 histopathologically confirmed OSCC tissue samples were included in case group along with an equal number of age and sex-matched normal tissue samples of oral cavity for the control group. c-Fos protein and m-RNA expressions were analyzed using immunohistochemistry and qRT-PCR, respectively. Results: A significant low expression of c-Fos protein was observed in OSCC cases than normal control subjects (p= <0.001). The mean percent positivity of c-Fos protein in cases vs. controls was 24.91± 2.7 vs. 49.68± 2.2 (p= <0.001). Most OSCC tissue samples showed weak or moderate c-Fos expression whereas 53.8% of normal tissue sections presented with strong immunostaining. Moreover, the relative m-RNA expression for the c-fos gene was significantly decreased in case group (0.93± 0.48) as compared to the control group (1.22± 0.87). Majority of c-Fos positive cases were diagnosed with well developed tumor. The mean percent positivity of c-Fos protein was significantly lower in higher grade tumor as compared with normal oral mucosa (p= < 0.001). Conclusion: The present study suggested that the c-fos gene is downregulated in oral carcinomas. The disparity of c-Fos protein levels in different pathological grades of tumor and normal oral tissue samples may indicate that loss of c-Fos expression is related with the progression of OSCC.

Abstract
Purpose The purpose of the study was to qualitatively and quantitatively assess bone regeneration potential of tentpole technique using beta tricalcium phosphate bone graft in vertically deficient alveolar ridges. Materials and Method This prospective study comprised of 20 patients with vertically deficient alveolar ridges, wherein thirty one implants were placed. Tenting of the soft tissue matrix was done using titanium screws and beta tricalcium phosphate synthetic bone graft was filled in the vertical defect. Clinical and radiographic assessment was done at 1, 3 and 6 months. Preoperative biochemical analysis of Osteopontin and RANKL was done and then reassesed at 3 months postoperative. Bone core collected at 6 postoperative months, while removal of screw, was analysed histologically. Results A significant gain in bone height of 2.87 ± 0.79 mm was seen at 6 months postoperative. All implants osseointegrated. Loosening of screw was seen in two patients.There was no postoperative wound dehiscence. Histologic analysis revealed new bone formation .There was no significant change in the levels of RANKL and Osteopontin at 3 months postoperative. Conclusion This is a safe and effective technique for bone regeneration in vertically deficient alveolar ridges and has minimal complications. The regenerated bone has new and viable bone content and supports implant material. More studies with long term follow up are needed to assess the stability of bone after long term loading.

Abstract
INTRODUCTION The goal in treating Hemifacial microsomia (HFM) is to improve facial symmetry, allow functional jaw movement, obtain stable occlusion, and achieve patient satisfaction. This study was planned with an aim to assess the outcome of simultaneous maxillomandibular distraction osteogenesis in hemifacial microsomia. MATERIAL & METHODS Seven patients with hemifacial microsomia were included in this study and demographic data was obtained. Simultaneous maxillo-mandibular distraction was planned for correction of maxillary cant, vertical ramal lengthening and midline, by performing unilateral mandibular osteotomy in ramus and distractor fixation, a Le Fort I osteotomy, with fixation at contralateral zygomatic buttress and intermaxillary elastics. Derriford Appearance Scale was used to measure individual responses to address problems of appearance. RESULTS 6 males and 1 female, with age range 18-26 years, mean 22.14 were included in the study. Maxillary occlusal cant varied from 4-16°, mean 9.85° and distraction achieved ranged from 12-19 mm, mean 15.57. Preoperatively DAS score ranged from 42-61, mean 51.7 and improved to 10-27, mean 18.4. 100% success was achieved in 5 cases, while other two showed 96% and 99% success. CONCLUSION Simultaneous maxillomandibular distraction osteogenesis improves facial esthetics and obviates the need for postoperative orthodontics, minimizing the treatment period.

Abstract
AIM The aim is to review the English literature for post-traumatic superolateral dislocation of mandibular condyle (SDMC),discuss their dynamics and clinical management and to propose to modify the existing classification of SDMC. PATIENTS AND METHODS A literature search was carried at Pubmed, Sciencedirect, Google and references from reported articles were crosschecked to look for the cases of SDMC from 1969 to 2015 in English language. Also, we have reviewed 11 of our patients with total of 18 superolateral dislocated intact or sagittal split condyles ,who visited our unit in the previous two years. RESULTS In our retrospective analysis 58 cases of SDMC were found in the literature, of which 38 had intact mandibular condyles and 20 had sagittal split. Early and intact SDMC were successfully managed conservatively with closed reduction, whereas old cases and largely fractured condyles necessitated open reduction. Additionally, we observed an unusual dislocation associated with fracture of contralateral posterior mandible(angle) in our series which did not gratify the existing classification. CONCLUSION Alteration of the existing classification was required to accommodate the unusual type of dislocation.
