Abstract
Purpose The choice of wound closure material may influence the clinical outcomes of intra-oral incision closure. Studies evaluating the application of barbed suture in the oral cavity are scarce. Hence, the present study was carried out with the aim to monitor and compare the efficacy and ease of handling of monofilament polyglycolide caprolactone (PGCL) unidirectional barbed and non-barbed sutures used for intra-oral incision closure in patients undergoing transalveolar extraction of impacted mandibular third molar and mandible fracture open reduction internal fixation. Methods A prospective randomized open label study was carried out among subjects requiring intra-oral incision closure following mandibular third molar extraction and isolated mandible fracture fixation. The difficulty index of the impacted third molars was evaluated pre-operatively. Subjects were randomized to receive either 3-0 monofilament PGCL unidirectional barbed or non-barbed sutures. Incision closure time and ease of suture handling were recorded intra-operatively. Post-operatively, patients were monitored for incision healing using the Hollander wound evaluation scale (HWES) and intensity of pain using visual analog scale (VAS) on post-operative days 1, 3 and 7. Data analysis involved descriptive statistics, Chi-square, unpaired t test and multivariate analysis using the IBM SPSS-PC software (v.25.0). Results A total of 60 subjects completed the study protocol, who were randomized into two groups (n1 = n2 = 30), comparable in terms of age, gender and treatment (TAE = 51; ORIF = 9) received. The incision healing outcomes were significantly better (p = 0.016) with barbed suture using HWES on day 7. The mean closure time using barbed suture (142.50 ± 34.803 secs) was significantly (p = 0.001) shorter than that with non-barbed suture (204.56 ± 52.94 secs). The mean VAS for the barbed suture (0.97 ± 1.89) was less (p = 0.015, 95% CI) than the non-barbed suture (2.50 ± 2.91) on day 3. The suture handling ease was comparable between the two groups. Conclusion Monofilament unidirectional PGCL barbed suture has merits over the non-barbed suture with regards to superior post-operative incision healing, reduced incision closure time (43%), lower post-operative pain and comparable ease of suture handling. Hence, knotless PGCL suture is a promising alternative for intra-oral surgical incision closure in oral and maxillofacial surgery.

Abstract
This article aims to review the literature about the history of fluoride, its toxicity, prevalence, prevention, diagnosis, and management in oral healthcare practice. Fluoride is the cornerstone of oral health, playing a pivotal role in oral health. Fluoride can be administered topically or systemically. Topically, it is found in toothpaste, mouth rinses, and professional treatments such as fluoride varnish. These directly shield teeth from decay and strengthen the existing enamel. Systemically, fluoride is ingested through water, foods, or supplements, benefiting tooth development, especially in children. Nevertheless, responsible fluoride use is essential. Overexposure can lead to dental fluorosis, affecting tooth aesthetics. Consulting a dentist for personalized guidance on fluoride usage can help strike the right balance between oral protection and potential side effects, ensuring a radiant and healthy smile for life.

Abstract
Aim This electronic survey was carried out to assess the knowledge, attitude, and practices among the oral health practitioners. Methods A questionnaire survey was conducted among undergraduates, graduated practitioners, and specialist practitioners. A Google Form that included a specified instruction format, informed consent with a clear description of the purpose of the study, and questions in different categories were sent through Whatsapp and email. Descriptive statistics were used to analyze responses. The association of knowledge and attitude with respect to oral health professionals was analyzed with the Chi-square test. Results The questionnaire was completed by 570 participants. Thirty percent of participants encountered ADR related to the drugs available in the market and 33.2% of participants encountered adverse reaction related to materials used in practice. ADR should be reported as soon as it is detected, according to this study about 12.1% of participants reported the ADRs, and this reporting is primarily for patient safety. Almost 66.8% of participants perceived that dental products can cause ADR owing to a lack of information about ADR and reporting procedures, or due to fear of legal concerns. Only about 9.5% of the participants had previously attended an ADR workshop. Conclusion Oral health practitioners have a general understanding of ADR; however, there is substantial evidence of underreporting and a lack of reporting system information. Organizing an orientation program and raising awareness about ADR reporting could help improve spontaneous reporting and better patient care.

Abstract
INTRODUCTION The adverse events of sutures used for the closure of surgical incisions influence clinical outcomes. Literature on the safety profile of the application of unidirectional barbed sutures in oral and maxillofacial surgery is scarce. Hence, focused materiovigilance was done to monitor and compare the adverse events of unidirectional barbed and poliglecaprone 25 nonbarbed sutures for intraoral incision closure. METHODS In a prospective randomized comparative study, 64 patients requiring intraoral incision closure were randomized to receive either unidirectional barbed or poliglecaprone 25 nonbarbed sutures. Postoperatively, patients were monitored for any adverse events for 15 days. Causality association of adverse events with sutures was done using the European Commission directives on safety reporting of medical devices. RESULTS Adverse events observed with unidirectional barbed suture were suture extrusion (n = 7; 21.875%) and suture discomfort (n = 3; 9.375%). While subjects who received poliglecaprone 25 suture experienced suture discomfort (n = 6; 18.75%) and knot unraveling (n = 2; 6.25%). The number of adverse events in both groups was statistically comparable (P = 0.78). Causality assessment of adverse events was probable for suture extrusion and discomfort with nonbarbed and barbed sutures, while it was possible for knot unraveling for nonbarbed sutures. CONCLUSION Both types of study sutures were associated with minor severity adverse events when used for the closure of intraoral surgical incisions. Suture extrusion had a probable causal association with barbed suture. Knot unraveling was possibly associated with the nonbarbed suture. Both types of suture materials were equally safe in oral and maxillofacial intraoral surgical incision closure.

Abstract
Abstract
Study question
To compare the efficacy of transdermal testosterone with placebo (lubricant gel) in improving IVF outcomes using GnRH antagonist protocol in POSEIDON group 3 and 4 patients.
Summary answer
Patients receiving pre-treatment with testosterone gel had higher mean number of oocytes retrieved and grade A embryos as compared to the patients receiving lubricant gel.
What is known already
Diminished ovarian reserve (DOR) is associated with suboptimal ovarian response, higher cycle cancellation rate and lower clinical pregnancy rate following IVF cycles. Various treatment regimens have been devised for management of such patients and use of adjuvants in the form of oral or transdermal androgen is one of them. Androgens improves follicular response to gonadotropin stimulation as well as increase FSH receptor expression in granulosa cells, in turn leading to better oocyte yield and pregnancy rate. Aim was to compare the effect of transdermal testosterone gel with placebo gel on ART outcome in DOR patients (POSEIDON Group 3 and 4).
Study design, size, duration
A prospective, randomised controlled trial was carried out from 1st September 2019 to 31st October 2020 at a tertiary infertility centre in India. 50 patients fulfilling the criteria of Group 3 and Group 4 of POSEIDON classification were included in the study. Patients with endocrine disorders (thyroid, prolactin), endometrioma, history of surgery on the ovaries, sensitivity to testosterone gel, male factor infertility and deranged liver and renal function tests were excluded.
Participants/materials, setting, methods
Enrolled patients were randomised into two groups of 25 patients each, one group was pretreated (TTG group) with transdermal testosterone gel, 12.5 mg/day from day 6th of previous cycle to day 2nd of stimulation cycle while patients in other group took lubricant gel for the same duration before stimulation with GnRH antagonist fixed protocol followed by fresh Day 3 transfer.
Main results and the role of chance
The baseline characteristics of the two groups were comparable. The primary outcome measures were the number of oocytes retrieved and number of grade A embryos formed (according to Istanbul consensus). The secondary outcome measures were implantation rate, clinical pregnancy rate, miscarriage rate and ongoing pregnancy rate. The mean number of oocytes retrieved in TTG group was 5±1.02 which was significantly higher than placebo group–3.5±1.2, (p < 0.001). The mean number of Grade A embryos were also significantly higher (4.78±0.54 vs 3.00±0.23, p < 0.001) in TTG group. The TTG group had higher implantation rate (28% vs 20%, p = 0.49), clinical pregnancy rate (32% vs 18%, p = 0.41), ongoing pregnancy rate (32% vs 16%, p = 0.38) and lower miscarriage rate (0% vs 20%, p = 0.38), however, these differences were not statistically significant.
Limitations, reasons for caution
The study was done at a single centre with small sample size, replication with more subjects and in different centers is needed.
Wider implications of the findings: Pre-treatment with testosterone gel in DOR patients improves ovarian response to stimulation and results in higher number of oocytes retrieved and good quality embryos resulting in improved clinical pregnancy rates. Transdermal testosterone is advantageous because of better bioavailability, easy application, patient friendly and less adverse effects.

Abstract
Jaw lesions in the pediatric population, although infrequently encountered in clinical practice, can cause functional impairment and cosmetic disfiguring. It is further complicated by the difficulty in diagnosis due to complex anatomy and facial developmental process during infancy and childhood. Intraosseous pediatric jaw lesions may vary from odontogenic to nonodontogenic types with nonspecific clinical features in most cases. They deserve careful attention by a systematic approach to provide a relevant diagnosis or differential diagnosis for timely management. Imaging plays a major role in diagnosis with orthopantomograph being the foremost investigation, followed by cross-sectional imaging, essentially computed tomography as a problem-solving tool. This article highlights the imaging spectrum of various jaw lesions in the pediatric population with a pattern-based approach for radiological diagnosis.

Abstract
Cancer cells exhibit distinct energy metabolic pathways due to multiple oncogenic events. In normoxia condition, the anaerobic glycolysis (Warburg effect) is highly observed in head and neck squamous cell carcinoma (HNSCC). HNSCC is associated with smoking, chewing tobacco, consumption of alcohol or Human Papillomavirus (HPV) infection primarily HPV16. In recent years, the correlation of HPV with HNSCC has significantly expanded. Despite the recent advancement in therapeutic approaches, the rate of HPV infected HNSCC has significantly increased in the last few years, specifically, in lower middle-income countries. The oncoproteins of High-risk Human Papillomavirus (HR-HPV), E6 and E7, alter the metabolic phenotype in HNSCC, which is distinct from non-HPV associated HNSCC. These oncoproteins, modulate the cell cycle and metabolic signalling through interacting with tumor suppressor proteins, p53 and pRb. Since, metabolic alteration represents a major hallmark for tumorigenesis, HPV acts as a source of biomarker linked to cancer progression in HNSCC. The dependency of cancer cells to specific nutrients and alteration of various metabolic associated genes may provide a unique opportunity for pharmacological intervention in HPV infected HNSCC. In this review, we have discussed the molecular mechanism (s) and metabolic regulation in HNSCC depending on the HPV status. We have also discussed the possible potential therapeutic approaches for HPV associated HNSCC through targeting metabolic pathways.

Abstract
The objective of this project was to retrospectively evaluate changes in volume of different compartments of the upper airway in response to maxillary, mandibular, and bimaxillary advancement surgeries and to predict the extent of volumetric changes associated with these surgical movements. Pre- and post-surgical cone beam computed tomography scans of 36 patients were evaluated for changes in nasal cavity, nasopharyngeal, oropharyngeal, and hypopharyngeal compartments. The amount of movement for each surgery was measured from skeletal landmarks to reference planes and was correlated with volumetric changes. Maxillary advancement of 4.0±2.2mm increased the oropharyngeal volume significantly (41.40%), and mandibular advancement of 3.8±1.6mm also significantly increased the oropharyngeal volume (21.17%). Bimaxillary advancement of 5.1±1.3mm for the maxilla and 6.4±3.1mm for the mandible significantly increased nasopharyngeal (27.45%), oropharyngeal (66.39%), and hypopharyngeal (52.48%) volumes. Furthermore, for every millimeter anterior movement, oropharyngeal volume increased by 2319.2±771.8mm3. Bimaxillary advancement showed a greater increase than isolated maxillary and mandibular advancement in all pharyngeal compartments. Every millimeter of advancement in the bimaxillary group led to a significant increase in oropharyngeal volume, while every millimeter downward movement showed a significant increase in nasopharyngeal volume.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC) is a cancer of the oral cavity that is a major health problem in India. There is an urgent need to identify biomarkers that have prognostic significance. We studied HIF-1α levels as well as single-nucleotide polymorphism of HIF-1α gene in cancer and healthy controls. METHODS Fifty newly diagnosed OSCC patients and 50 age and sex-matched healthy control were included in the study. Serum concentrations of HIF-1α were measured by sandwich ELISA; whereas HIF-1α gene polymorphism study was performed using restriction enzyme digestion by HpH I. RESULTS The major genotype observed was CC genotype in both control (84%) and patients (86%) followed by CT genotype (control 16%, cases 14%). CT genotype led to more aggressive tumors. On subgroup analysis based on prognosis, the median overall survival of patients who were treatment responders was 488 days (16.2 months) and that of the patients with progressive disease was 365 days (12.1 months). The patients who expired during the study observation period had median survival of 330 days (11 months). CONCLUSION Our study showed that CT genotype for C1772T polymorphism of HIF-1α predisposes to aggressive tumor phenotype in patients with OSCC. Moreover, patients with CT genotype had poor survival rate as compared to CC genotype. A cut-off value of 460 pg/mL of HIF-1α can help to segregate patients with OSCC from healthy controls.

Abstract
ABSTRACT
Introduction
Oral squamous cell carcinoma (OSCC) is a major health problem in Southeast Asia, including India. Areca nut chewing is a major health hazard in India, which has been implicated in the etiology of OSCC. Hypoxia-inducible factor-1 (HIF-1) is a major transcription factor involved in adaptation under hypoxic condition, a common finding in solid tumors. The present study was conducted to evaluate the effect of different habits including areca nut chewing on HIF-1 expression in patients with OSCC.
Materials and methods
It was a hospital-based observational case-control study. The study comprised 50 histologically proven cases of OSCC and 50 healthy controls. The HIF-1α level was measured by commercially available enzyme-linked immunosorbent assay (ELISA) in the blood samples. The data were analyzed using Statistical Package for the Social Sciences (SPSS) software version 20.
Results
The HIF-1α levels were found significantly higher in the patients with areca nut consumption in addition to other addictive habits. Isolated influence could not be discerned as there was only one patient who gave history of only areca nut chewing.
Conclusion
Our findings prove that HIF-1α expression is upregulated by areca nut chewing, which leads to worse prognosis. This calls for widespread awareness programs regarding the deleterious effects of areca nut chewing among the general population.

Abstract
Rice and chickpea GDPD s are transcriptionally influenced by mineral deficiencies; especially, by phosphate starvation and CaGDP1 encodes an active glycerophosphodiester phosphodiesterase enzyme. Glycerophosphodiester phosphodiesterases (GDPDs) are enzymes involved in the degradation of glycerophosphodiesters into sn-glycerol-3-phosphate and corresponding alcohols. These phospholipid remodeling genes have been suggested to play important roles in phosphate homeostasis. However, comprehensive information about the role of GDPDs under low phosphate (P) and other nutrient deficiencies (N, K, Fe, Zn) in rice and chickpea is missing. Here, we identified 13 OsGDPDs and 6 CaGDPDs in rice and chickpea, respectively, and partly characterized their roles in multiple nutrient stresses. Expression profiling after 7 and 15 days of deficiency treatments revealed unique and overlapping differential expression patterns of OsGDPDs and CaGDPDs under different nutrient stresses. Principal component analysis on the expression patterns of OsGDPDs and CaGDPDs revealed their preferential role in P starvation. Some of the GDPDs were also induced by N, K, Fe and Zn deficiency in temporal manner in both crops suggesting their roles in multiple nutrient stresses. Biochemical characterization of highly responsive chickpea GDPD, CaGDPD1, confirmed its in vitro GDPD activity and revealed its optimal temperature, pH and cofactor requirements. Further, CaGDPD1 showed its accumulation in ER and endomembranes. We hereby propose CaGDPD1 and various OsGDPDs as low P responsive marker genes in chickpea and rice, respectively. Our data uphold role of GDPDs in multinutrient responses and suggest them as candidates for rice and chickpea improvement for tolerance to various nutrient deficiencies.

Abstract
Torezolid (TR-700) is the active moiety of the prodrug torezolid phosphate ([TP] TR-701), a second-generation oxazolidinone with 4- to 16-fold greater potency than linezolid against Gram-positive species including methicillin-resistant Staphylococcus aureus (MRSA). A double-blind phase 2 study evaluated three levels (200, 300, or 400 mg) of oral, once-daily TP over 5 to 7 days for complicated skin and skin structure infections (cSSSI). Patients 18 to 75 years old with cSSSI caused by suspected or confirmed Gram-positive pathogens were randomized 1:1:1. Of 188 treated patients, 76.6% had abscesses, 17.6% had extensive cellulitis, and 5.9% had wound infections. S. aureus, the most common pathogen, was isolated in 90.3% of patients (139/154) with a baseline pathogen; 80.6% were MRSA. Cure rates in clinically evaluable patients were 98.2% at 200 mg, 94.4% at 300 mg, and 94.4% at 400 mg. Cure rates were consistent across diagnoses, regardless of lesion size or the presence of systemic signs of infection. Clinical cure rates in patients with S. aureus isolated at baseline were 96.6% overall and 96.8% for MRSA. TP was safe and well tolerated at all dose levels. No patients discontinued treatment due to an adverse event. Three-stage hierarchical population pharmacokinetic modeling yielded a geometric mean clearance of 8.28 liters/h (between-patient variability, 32.3%), a volume of the central compartment of 71.4 liters (24.0%), and a volume of the peripheral compartment of 27.9 liters (35.7%). Results of this study show a high degree of efficacy at all three dose levels without significant differences in the safety profile and support the continued evaluation of TP for the treatment of cSSSI in phase 3 trials.

Abstract
Ameloblastic carcinoma is a very rare malignant odontogenic tumour with characteristic histopathological and clinical features, which requires aggressive surgical treatment and surveillance and, therefore, differs from ameloblastoma. Metastasis typically occurs in the lung. Only one patient with metastasis to the skull has previously been described and no prior case reports have presented MRI and positron emission tomography-CT (PET-CT) imaging findings. We describe a case of ameloblastic carcinoma with metastasis to the skull and lung with emphasis on imaging features including MRI and PET-CT.

Abstract
BACKGROUND The decision to get impacted teeth removed is not straightforward because of the concerns about its possible outcome. Assessment of quality of life is now regarded as an essential component for assessing outcomes of dental health care. The purpose of this paper is to assess the effect of impacted third molar teeth surgery on a number of health related outcomes. PATIENTS AND METHODS A total of 72 patients undergoing surgical removal of their unilateral impacted mandibular third molar teeth were recruited to participate in this study. Patients were asked to complete two questionnaires, 14-item Oral Health Impact Profile (OHIP-14) and the 16-item UK Oral Health related Quality of Life measure questionnaire (OHQOLUK-16) daily for one week following surgery. RESULTS There was significant decrease in the mean OHQOLUK-16 score and OHIP-14 scores for the first five postoperative days. There were no significant differences in changes in the mean OHIP-14 scores or OHQOLUK-16 scores on postoperative day 6 and 7. CONCLUSION There was a significant deterioration in oral health related quality of life in the immediate postoperative period, which slowly returned to preoperative level by day 6. This information may be useful in creating realistic expectation for patients who are considering third molar surgery.

Abstract
Odontomas are the most common type of odontogenic tumors and are generally asymptomatic. This paper describes the case of a complex composite odontoma in a patient who had an asymptomatic swelling in the maxillary molar region, along with the impacted third molar. In this case, surgical excision of the lesion was performed, and the impacted third molar was intentionally left in situ so that it could erupt to the level of occlusion.

Abstract
Obstructive sleep apnea (OSA) syndrome is a common disorder that has recently received much attention by the medical community due to its potentially serious physiological consequences. The clinical significance of OSA results from hypoxemia and sleep fragmentation caused by collapse of the airway, which leads to apnea or hypopnea during sleep. This paper reviews common surgical techniques used for clinical management of OSA patients, with emphasis on jaw advancement surgical procedures.

Abstract
This study was undertaken to evaluate the stability of maxillary advancement using bone plates for skeletal stabilization and porous block hydroxyapatite (PBHA) as a bone graft substitute for interpositional grafting in cleft and non-cleft patients. The records of 74 patients (41 females, 33 males) who underwent Le Fort I maxillary advancement using rigid fixation and PBHA interpositional grafting were evaluated retrospectively. All patients also underwent simultaneous sagittal split mandibular ramus osteotomies. Patients were divided into 2 groups for study purposes: group 1 consisted of 17 cleft palate patients and group 2 consisted of 57 non-cleft patients. Each group was further subdivided into 2 subgroups based on the concurrent vertical positioning of the maxillary incisors: groups 1a and 2a, where the maxilla underwent 3 mm or more of inferior repositioning, and groups 1b and 2b, where the maxilla underwent minimal vertical change (< or = 1 mm). Presurgery, immediate postsurgery, and longest follow-up lateral cephalometric tracings were superimposed and analyzed to calculate surgical change and long-term stability of results by assessing horizontal and vertical changes at point A, incisor superius, and the mesial cusp tip of maxillary first molar. The average follow-up time in group 1 was 37.9 months (range 12 to 136) and in group 2 was 28.77 months (range 17 to 88). Average maxillary advancement at point A was: group 1a, 5.4 mm; group 1b, 5.25 mm; group 2a, 5.48 mm; group 2b, 5.46 mm. Average relapse at point A was: group 1a, -0.75 mm; group 1b, -1 mm; group 2a, -0.47 mm; group 2b, -0.48 mm. Average horizontal and/or vertical relapse at the central incisors and first molars was 1 mm or less in group 1 and less than 0.5 mm in group 2. Although there was a slightly greater relapse in group 1, no statistically significant difference was observed between the groups. Maxillary advancement with Le Fort 1 osteotomies using rigid fixation and interpositional PBHA grafting during bimaxillary surgery is a stable procedure with good predictability in cleft and non-cleft patients, regardless of the direction of vertical maxillary movement.

Abstract
This study evaluated our treatment outcomes in 105 patients (188 discs) using the Mitek mini anchor for temporomandibular joint (TMJ) articular disc repositioning surgery, with 88 patients having simultaneous orthognathic surgery. Criteria for inclusion into the study were: (1) Presurgical TMJ disc displacement with salvageable disc; (2) No prior TMJ surgery; (3) TMJ disc repositioning with the Mitek mini anchor; (4) Absence of connective tissue/autoimmune disease; (5) Absence of postsurgical trauma; and (6) Minimum of 12 months postsurgery follow up. Presurgery (T1), immediately postsurgery (T2), and longest follow up (LFU) clinical and radiographic evaluations were performed. The mean age of the patients was 32.6 years (range 14-57 years), and mean follow-up time was 46.2 months (range 14-84 months). Radiographic evaluation at LFU demonstrated no significant condylar resorption or positional changes of the anchors. At LFU, there was a statistically significant reduction in: TMJ pain, facial pain, headaches, TMJ noises and disability, and improvement in jaw function and diet. Maximum incisal opening improved slightly and lateral excursive movements decreased slightly. The Mitek mini anchor provides a predictable method for stabilizing the TMJ articular disc to the condyle and a high success rate in decreasing TMJ dysfunction and pain in patients with no previous TMJ surgery.

Abstract
OBJECTIVE The purpose of this study was to present a new technique for limiting mandibular translation in patients with chronic mandibular dislocation. TECHNIQUE DESIGN: This relatively simple procedure uses 2 Mitek mini bone anchors with osseointegration potential. One anchor is placed in the lateral pole of the condyle, and the other is placed in the posterior root of the zygomatic arch. Heavy suture material is threaded through the eyelet of each anchor and tightened to function as a restraining ligament. RESULTS This technique has been used on 5 patients with a follow-up of 2 to 4 years, with no failures. CONCLUSIONS This technique provides an effective method for the prevention of condylar dislocation while permitting some controlled translation.
