Medial Pterygoid Abscess Masquerading as a Temporomandibular Joint Disorder: A Case Report.

A patient presenting with a history of restricted mouth opening and deflection of the mandible after a prolonged dental procedure raises a suspicion of temporomandibular joint disorder (TMD) due to its estimated high prevalence of 29%. Muscle relaxants and routine active physiotherapy established normal range of movement and pain reduction was achieved through TENS therapy and analgesics. However, the non-subsidence of deflection prompted an initial suspicion of TMD which was overturned by MRI. The MRI evaluation revealed left side medial pterygoid abscess. It is imperative to understand that despite strong history and relevant clinical features, for the definitive diagnosis radiographic evaluation is highly contributory. Misdiagnosing TMD due to its similar presentation can have significant implications for the patient's well-being and quality of life. The clinical features of medial pterygoid abscess including restricted mouth opening and pain can be similar to that of TMD. These abscesses are most commonly caused by odontogenic infections but can also occur as a result of septic inferior alveolar nerve block techniques. Limited literature reports of pterygoid space abscess have been described, but intramuscular and medial pterygoid abscess is an absolute rarity. Causal relationship to septic inferior alveolar nerve block further makes this case report an interesting read.

Heterotopic Ossification After Reconstruction with Free Fibula Flap - an Ambiguous Mishap.

Heterotopic ossifications (HO) are rare, yet, well reported complications after free flap transfer. We present a case of HO that occurred within a month, and has not been previously described in the literature. This serves as a reminder that bony hard swellings proximal to the free flap within a month should raise the suspicion of HO.

Hindi Translation of Oral Health-Related Quality of Life (OHRQoL) Questionnaire and its Validation for Oral Submucous Fibrosis Patients: A Pilot Study.

Background: Oral Submucous fibrosis has a substantial burden on the Indian population; thus there is a substantial need for a validated questionnaire assessing QoL in Hindi. Thus, a prospective cross-sectional study was designed to translate and validate the English version of the OHR QoL-OSF questionnaire into Hindi. Methodology: We followed the guidelines suggested by the European Organisation for Research and Treatment of Cancer (EORTC) for the translation procedure and subsequently validated the translated questionnaire with reliability and validity. Results: A total of 50 patients were included in this pilot study. Cronbach's alpha for 17 items was 0.87 signifying high reliability. All questions had an I-CVI of 1.00, demonstrating complete agreement among the content experts regarding the relevance and clarity of items in the questionnaire. Convergent validity was adequately established for all factors except for factor 3 for which it was around 0.43. The intraclass coefficient was 0.803 showing good agreement between the test-retest results. Conclusion: The Hindi version of the OHR QoL questionnaire is a reliable instrument having good reliability, good content, good acceptability, and good responsiveness, and thus appears to be a valid instrument. Large studies with large sample sizes can be conducted in the future. Supplementary Information: The online version contains supplementary material available at 10.1007/s12663-023-01927-2.

Minimal clinically important difference in maxillofacial trauma patients: a prospective cohort study.

The present study estimated the minimal clinically important difference (MCID) for pain on a visual analogue scale - numerical rating scale (VAS-NRS) and mean bite force (MBF) in patients treated for maxillofacial trauma (MFT). This cohort study included 120 MFT patients treated according to AO principles. Preoperative and four-week postoperative pain on the VAS-NRS, and MBF were measured to calculate MCIDs as indicators of functional rehabilitation. The patient's perspective of the treatment was assessed using a four-item anchor question. The MCID was determined by two anchor-based approaches, namely, the change difference (CD) method and receiver operating characteristic (ROC) curve method. According to the CD method, the MCID for pain was 2.4 and the MBF was 147.9 N. Based on the ROC curve, the MCID for pain was 2.5 (sensitivity 91.7%, specificity 47.2%) and MBF was 159.1 N (sensitivity 71.4%, specificity 61.1%). This study demonstrated a high sensitivity (>70%) for MCID, which implies that pain reduction of 2.4-2.5 points on the VAS-NRS and a gain in MBF of 147.9-159.1N are clinically relevant for patients treated for MFT.

Efficacy of Oral Magnesium on Bone Regeneration and Implant Stability in Immediate Dental Implants: A Randomized Controlled Trial.

PURPOSE: The successful osseointegration around immediate implants requires high quality and quantity of osteogenesis around them. The role of magnesium as a boneenhancing mineral, and as an adjunctive analgesic has been well documented in orthopedic literature. However, there is a paucity of literature in its role in successful osseointegration around immediate implants. This randomized controlled trial sought to assess the promising impact of magnesium on osseointegration by examining various aspects of implant stability, correlating them with serum bone markers, and establishing a foundation for future research on its potential as a potent analgesic. MATERIALS AND METHODS: Immediate implant placement was done after the extraction of the indicated mandibular molar tooth, and all the patients were segregated into 2 groups (Placebo- Lactose, and Magnesium citrate). Bone regenerate in the peri-implant area was assessed radiographically immediate post-operatively, on the 6th week and 12 weeks. Implant stability was measured immediate post-operatively, at the 4th week and 12th week. Serum parameters were procured pre-operatively and post-operatively for serum calcium, serum alkaline phosphatase (ALP), and serum parathyroid hormone at the 8th week, and serum vitamin D3 levels preoperatively. RESULTS: 54 immediate implants placed showed the demographics and baseline serum, clinical, and radiographic parameters were comparable in both groups. Analysis of Implant Stability Quotient at 12th week showed statistically significant difference in intervention group both on intergroup and intragroup analysis. Radiodensity measurement showed a statistically significant difference in both intragroup and intergroup analysis in the intervention group at the 6th and 12th week. In bone gap analysis, the difference in mean change in the horizontal bone gap (HG) at 6 weeks was non-significant while the difference in HG at the 12th week was significant in the intervention group. On intragroup analysis, mean change HG at 6 weeks and 12 weeks both were significant only in intervention group. Intergroup analysis of vertical bone gap (VG) 12 and VG 12-0 (mean difference in the vertical bone gap from 12th week-day 0) showed a statistically significant difference in the intervention group. On intragroup analysis, VG 12 was significantly better in the intervention group. On serum analysis, ALP post-operatively was found to be significantly raised (P=0.013) in intervention group. Numerical rating Scale (NRS) analysis showed a significant decrease in post-op day 5 and 7, (P=0.017) and (P=0.002) respectively. CONCLUSION: The oral magnesium citrate supplementation after immediate implant placement helps in enhancing the stability of the immediate implants, along with improved radiodensity around them which was found to be statistically significant. It also helps in reducing the horizontal, and vertical gap around the implant and has significant analgesic potential.

Comparison of Teriparatide and Combination of Cissus Quadrangularis and Dalbergia Sissoo on Bone Healing Against the Control Group in Maxillofacial Fractures: A Randomized Open-label Control Trial.

Study Design: Randomized Control Trial. Objective: A randomized control trial was planned to aim to assess whether subcutaneous Injection of Teriparatide and Tablet Reunion (combination of Cissus Quadrangularis and Dalbergia sissoo) improves maxillofacial fracture healing as compared to the control group. Methods: 24 patients of mandibular fracture with or without concomitant maxillofacial fractures were randomly divided into 3 equal groups (Group 1- Control, Group 2- Tablet Reunion, and Group 3- Injection Teriparatide) and the treatment duration was 4 weeks. Pain, fracture site mobility, bite force, serum markers, and radiographic healing were assessed preoperatively and postoperatively at regular intervals till 12 weeks. Results: Group 2 showed early pain relief, although it was insignificant. Group 3 showed the highest anterior bite force at all the time points. Change in mean posterior bite force (PBF) showed a statistically significant increase at 8th week and 12th week in intergroup comparison; however, at 12th week, Group 3 was significantly better than Group 1 and reported the highest posterior bite force compared to other groups. Serum calcium and PTH level showed no significant difference, whereas Serum ALP showed a statistically significant increase in Group 3. The radiographic assessment showed no significant difference among the 3 groups. Conclusions: Both the intervention group drugs showed a promising effect on accelerating the fracture healing and improving bite force restoration with the osteoanabolic action; however, early radiographic healing and increased serum osteogenic markers in Group 3 indicate its possible optimistic role in maxillofacial fracture healing.

Safety and Efficacy of Resveratrol in Healing of Maxillofacial Fractures: A Randomized Controlled Study.

Objectives: To assess the efficacy of resveratrol in improving functional outcomes following open reduction and internal fixation of maxillofacial fractures. Study Design: A single-center, randomized, parallel group, prospective, double-blind clinical trial was conducted on 40 patients between the age 20 and 60 years, requiring open reduction and internal fixation of maxillofacial fractures. The selected patients were randomly divided into two groups, Group 1 (placebo) and Group 2 (resveratrol) where tablets resveratrol 500 mg were given twice daily for 1 month following open reduction and internal fixation of fractured segments. Bite force was calculated pre-operatively and on the 1st, 4th, 8th and 12th week postoperatively. Serum markers osteocalcin and alkaline phosphate were calculated pre-operatively and at 4th and 12th week postoperatively. Results: Bite force (690.55 ± 262.00) in the resveratrol group was higher than the placebo group (553.27 ± 300.08) at 12th week postoperatively. However, the difference was non-significant statistically (p = 0.132). Resveratrol group (116.80 ± 55.25) showed better maintenance of serum ALP level as compared to placebo group (107.90 ± 42.99) at 12th week postoperatively, but again it lacked statistical significance (p = 0.573). Resveratrol group after initial reduction at 4th week showed serum osteocalcin levels nearly equal to the preoperative values at 12th week, while the placebo group showed a decline both at 4th and 12th week postoperatively. However, these results were not statistically significant (p = 0.065). Conclusion: There was no statistically significant difference in bite force, serum ALP level and serum osteocalcin levels between placebo group and resveratrol group. Though not statistically significant but early increased level of serum osteogenic markers, better restoration of bite force in group 2 (tab. Resveratrol) indicates toward its possible optimistic role in maxillofacial fracture healing. More studies with larger sample sizes are needed in order to confirm the efficacy of this drug in maxillofacial fracture.

Comparison of smear layer removing efficacy of Cold Atmospheric Pressure (CAP) Plasma Jet with different chelating agents. An ex-vivo study.

The present study aimed to assess the effectiveness of different final irrigation regimens (Cold Atmospheric Pressure Plasma Jet, MTAD, and EDTA) in removing the smear layer from intra-radicular dentin using a Scanning Electron Microscope (SEM). Eighty-four mandibular premolars were prepared with ProTaper Universal hand files and were equally divided into four groups i.e. Normal saline (control), EDTA, MTAD and CAP Plasma Jet. Prepared samples in the control, EDTA and MTAD groups were irrigated with 5 milliliters of the irrigant, and it was retained for 2 min. In the CAP Plasma Jet group, the plasma plume was directed towards the canal lumen for 2 min. The smear layer removal of all the groups was evaluated at the coronal, middle and apical thirds. Statistical analysis was performed using Kruskal-Wallis test followed by Dunn's test. Evaluation by SEM showed that the smear layer removal ability of MTAD and EDTA were significantly better than CAP Plasma Jet (p < 0.05). While CAP Plasma Jet showed results comparable to EDTA in the coronal third. In the middle and apical third of the canal, its effect was comparable to the control group (p > 0.05). MTAD and EDTA aided in better smear layer removal than the CAP Plasma Jet in the coronal, middle, and apical third of the test samples. CAP Plasma jet performed better in the coronal third.

Efficacy of Enhanced Recovery after Surgery (ERAS) protocol in maxillofacial trauma: A randomized controlled trial.

INTRODUCTION: Enhanced Recovery after surgery (ERAS) guidelines have been formulated in the literature for various different specialties but none is present for maxillofacial trauma patients. Hence, we have formulated ERAS protocol for maxillofacial trauma (ERAS-MT) patients and compared with the patients receiving the standard traditional care for post trauma outcomes. METHODOLOGY: A randomized controlled trial included 74 patients divided into two groups: Group 1 (ERAS group:37 patients) and Group II (Control group:37 patients). ERAS group were intervened according to the formulated ERAS protocol based on the previous literature and the control group received the standard of care. The both groups were compared for various post trauma outcomes. RESULTS: Baseline demographic data was non-significant between both the groups. There was significant decrease in pre-operative IV fluid use and total number of IV analgesics used till 72 h as well as in the immediate post operative period in the ERAS group(p = 0.001). ERAS group started oral feeds within 6 h and they were significantly compliant for oral carbohydrates in the pre-operative phase(p = 0.001). PONV episodes, swelling and infections were insignificantly less in the ERAS group(p > 0.05), however a significant difference was seen throat pain and decreased anxiety as well as Oral Hygiene Index(p = 0.001). At two weeks, a significant difference was seen in overall patient's satisfaction and cost analysis in the ERAS group (p = 0.001). CONCLUSION: Our study suggested that ERAS protocol was associated with shorter hospital stay, early recovery with better overall satisfaction of the patients, lesser post-operative complications and significantly decreased cost analysis.

Treatment Outcome Comparison Between two 3-Dimensional Plates (Y-Shaped Plate Versus Trapezoidal Condylar Plate) in Management of Mandible Condylar Fracture: A Randomized Control Trial.

Aim: To compare the treatment outcomes (clinical, functional and radiographical) using the two different 3-Dimensional plates in open reduction internal fixation of mandibular condylar fracture (MCF). Assessment of ease of fixation and fixation time were also performed. Methodology: 20 MCF patients were divided equally into two groups (Group A: Trapezoidal Condylar Plate and Group B: Y-shaped plate) and the treatment outcomes were compared. Intraoperatively time required for fixation was also compared. The patients were followed up at different timelines till 3 months. Result: Baseline parameters had statistically insignificant distribution in both groups implying effective randomization and balanced confounding factors. Intraoperatively, adequate anatomical reduction was achieved in both groups with statistically insignificant difference in time required for fixation. Postoperatively, no statistically significant difference was found in radiographic and functional parameters. None of the patients in either group reported with facial nerve injury, condylar resorption, Temporomandibular Disorders. However, 02 patients in Group A and 01 patient in Group B presented with infection, parotid fistula, and hardware failure respectively with statistically insignificant difference. Conclusion: This study concluded that the treatment outcomes were satisfactory with the use of both 3-D plate, but further studies with larger sample size and longer follow up are required.

Venolymphatic malformation of tongue: a prompt life saving intervention.

Venolymphatic malformations (VLMs) of the head and neck can have varied clinical presentation with associated complications. Timely diagnosis and treatment is warranted to curb the morbidity and obtain satisfactory outcomes. We present the case of a male patient in his early 20s with VLM of the tongue who received precise interventions which were executed with active contributions from a team of anaesthesiologists, interventional radiologists, oral and maxillofacial surgeons and intensivists. We highlight the importance of an immediate, comprehensive and multimodal treatment approach for VLMs of the maxillofacial region.

Quality of Life in Oral Submucous Fibrosis: A Systematic Review.

Backgrounds: Oral submucous fibrosis (OSMF) is a chronic, insidious disease and is said to have a multifactorial origin with varied clinical manifestation of repeated oral ulcers, intolerance to spicy food, mucosal blanching resulting in stiffness of the oral mucosa and formation of taut bands leading to reduced mouth opening. We designed this study to systematically review the literature on QOL in OSMF and hope to make recommendations for future course of QOL assessment in OSMF. Methods: An electronic bibliographic search of studies was done from year 1900-2019 using specified keywords. The following databases were searched: PubMed, Ovid, Google Scholar and manual search were done from references of relevant articles. Of the screened 156 articles, finally 10 studies were included after screening for inclusion/exclusion criteria. Quality assessment of studies was completed using the Effective Public Health Practice Project (EPHPP) criteria for quantitative studies. Results: Most instruments used in the studies were not disease specific for OSMF except one study. Six types of questionnaires were used. The heterogeneity in study population, study designs, QOL instruments and outcome measures made it difficult for a comparison. Therefore, a quantification analysis was not possible. Also pure OSMF data without the involvement of other lesions were less in number. Conclusions: OSMF not only physically debilitates a patient, it has its repercussions on the social, physical, psychological domains as well. Another aspect is that apart from trismus, which is the most common and evident symptom associated with OSMF, a substantial part of the suffering that ensues is also because of the ulcerations, burning sensation and worsening of dental health. Another focus was the association of worse QOL with a higher grade of disease, longer and higher tobacco abuse contact duration. This review is unable to give a confident answer to the evidence on QOL in OSMF but definitely showers light on the evident lack of robust data on the same. Robust Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation methodological and adequately powered studies on assessing QOL in OSMF using only a reliable disease specific questionnaire is the need of the hour.

Minimal clinically important difference of mouth opening in oral submucous fibrosis patients: a retrospective study.

Objectives: The purpose of this study was to estimate the minimal clinically important difference (MCID) of mouth opening (MO) and patient satisfaction in surgically treated oral submucous fibrosis (OSMF) patients. Materials and Methods: The status of MO was collected preoperatively (T0), postoperatively at 3 months (T1), and at a minimum of 6 months postoperatively (T2). MCID was determined through the anchor-based approach with the change difference method, mean change method, and receiver operator characteristic curve (ROC) method. Results: In this study, 35 patients enrolled and completed postoperative follow-up (T2) averaging a duration of 18.1 months. At T1, using the change difference method, MO was 14.89 mm and the ROC curve exhibited a 11.5 gain in MO (sensitivity 81.8% and specificity 100%, area under the curve [AUC] of 0.902) and was classified as MCID as reported by patients. At T2, MCID of MO was 9.75 mm using the change difference method and 11.75 mm by the mean change method. The ROC curve revealed that the MCID of MO at T2 was 10.5 mm with 73.9% sensitivity and 83.3% specificity (AUC of 0.873). The kappa value was 0.91, confirming reliability of the data. Conclusion: This study demonstrated MCID values that indicate the clinical relevance of surgical treatment of OSMF if the minimum possible gain in MO is approximately 10 mm.

Efficacy and Safety of Concentrated Growth Factors and Platelet- Rich Fibrin on Stability and Bone Regeneration in Patients with Immediate Dental Implants: A Randomized Controlled Trial.

PURPOSE: Immediate dental implants revolutionized the field of implant dentistry with significant advantages over conventional implants. The lack of adequate bone in the extraction socket raises the question of the appropriate timing of implant loading. Platelet concentrates have been used widely to accelerate bone regeneration in the maxillofacial region. This study evaluates the effect of platelet concentrates on bone healing and implant stability in the maxillary and mandibular molar regions. Bone regeneration is regulated by several growth factors, particularly vascular endothelial growth factor (VEGF) and transforming growth factor-ß1 (TGF-ß1); therefore, quantification of these factors in platelet concentrates and its correlation with bone healing has been assessed in this study. MATERIALS AND METHODS: The primary aim of this randomized clinical trial was to compare the stability of immediate dental implants in the maxillary and mandibular molar regions treated with platelet-rich fibrin (PRF) versus concentrated growth factors (CGF) using resonance frequency analysis (RFA). The secondary objectives were to evaluate the bone regenerate around implants with the use of PRF and CGF and to quantify growth factors VEGF and TGF-ß1 in the prepared CGF and PRF and their correlation with bone healing, if any. A total of 36 patients were randomized into three groups (12 each): control, PRF, and CGF. In all patients, immediate implants were placed either with or without platelet concentrate (PRF or CGF). Implant stability was measured using RFA immediately postoperatively and at 4, 8, and 12 or 16 weeks (12 weeks for mandible and 16 weeks for maxilla) postoperatively. Radiodensity and the bone gap (horizontal/vertical) were measured on intraoral periapical radiographs immediately postoperatively and at 8 weeks and 12 or 16 weeks postoperatively. RESULTS: On comparing the implant stability quotient (ISQ), radiodensity/grayscale (GS), and horizontal and vertical bone gap (HG and VG), there was no significant difference noted between the three groups at any point in time. On ISQ analysis at 8 weeks, the control group showed a significant improvement (P = .04), whereas at 12 or 16 weeks, significant improvement was seen in PRF (P = .03) and CGF groups (P = .02). In GS assessment, only the control group showed significant improvement at 12 or 16 weeks (P = .009). In horizontal and vertical bone gap analysis all three groups showed significant improvement at 8 weeks (control [P < .001], PRF [P = .001], CGF [P = .01]) as well as 12 or 16 weeks (control [P < .001], PRF [P < .001], CGF [P = .006]). The enzyme-linked immunosorbent assay (ELISA) quantification of VEGF and TGF-ß1 showed significant concentration of VEGF in PRF as compared to the plasma, while concentration of TGF-ß1 was found to be comparable in both groups. CONCLUSION: The application of platelet concentrates seems to enhance stability of implants, but intergroup results were nonsignificant at all time points. There was no statistically significant difference between the three groups when comparing quality (radiodensity/grayscale) and quantity (horizontal and vertical gap reduction) of bone regenerate. Studies with larger sample sizes are required to make conclusive assertions regarding efficacy of platelet concentrates in dental implants.

Transdermal fentanyl patch versus standard analgesia in postoperative oral submucous fibrosis patients: a triple blinded, randomised control trial.

Severe pain experienced by patients with oral submucous fibrosis (OSMF) compromises their physiotherapy and negatively affects the surgical outcome and the patient's compliance. The main aim of this study was to develop a protocol for pain control in the management of OSMF postoperatively. This was a prospective, parallel with active control, double-arm, triple-blinded, randomised control trial (RCT) with 48 OSMF patients, randomised into two groups - Group A (control, n = 25): received non-opioid analgesics (NSAIDs) and Group B (cases, n = 23): received transdermal fentanyl patches (TFP). Pain and interincisal opening were measured on postoperative days 1, 3, 5, 7, 9, and 15, and on the1st and 3rd postoperative months. Quality of Life (QoL) was assessed preoperatively, on the 15th day postoperatively, and 3rd month postoperatively, and compliance was documented postoperatively on the 9th day. The transdermal fentanyl patch was found to have statistically significantly more effect in controlling severe pain during active mouth opening exercises, and thus significantly increased the patients' compliance. Although there was increased mouth opening and QoL in the fentanyl group, the differences were statistically insignificant. Our study recommends the use of TFP for better pain control and compliance in postoperative OSMF patients.

Oral Manifestations of COVID-19 Infection: An Analytical Cross-Sectional Study.

Objectives: The current COVID-19 pandemic has created a huge impact across the globe. Recent literature has reported the occurrence of varied oral lesions in COVID-19 patients in the form of sporadic case reports. This analytical cross-sectional study was carried out to gauge and understand the pattern of oral lesions in qualitative RT-PCR-confirmed COVID-19 patients. Methods: A cross-sectional study involves a total of 500 qualitative RT-PCR confirmed, hospitalized COVID-19 patients who were meticulously scanned for any hard and soft tissue lesions developing concomitantly with the disease occurrence. Results: This study included a total of 367 (73.4%) males and 133 (26.6%) female patients with a mean age of 53.46 ± 17.50 years. Almost 51.2% of patients presented with gustatory disturbance, 28% with xerostomia and 15.4% of patients were found to have oral findings like erythema, ulcers, depapillation of tongue. There was a statistically significant correlation between oral manifestations and disease severity (p ≤ 0.001). Conclusion: COVID-19 is found to effect oral health with greater probability in patients with severe diseases (SARI) which may be due to disease itself, immune response and lack of motivation for personal hygiene measures.

2.5% EMLA Versus 2% Lignocaine with Adrenaline Injection in Small Oral Mucosal Biopsies: A Parallel Group Randomized Controlled Trial.

TRIAL DESIGN: The study was designed as an open label randomized comparative parallel group design with a 1:1 allocation ratio. METHODS: All consecutive patients reporting for small biopsies (incisional or excisional) who gave written informed consent were included in the study between October 2018 and October 2019. They were randomized into two groups, Group A and Group B both receiving intervention in the form of 2.5% EMLA cream and 2% Lignocaine with 1:80,000 Adrenaline injection respectively, to anaesthetise tissue for small mucosal biopsies in the oral cavity. RESULTS: EMLA was found to be as effective as lignocaine infiltration with a completely painless application and higher satisfaction for overall comfort during procedure. The duration required to achieve anaesthesia was however more. A particular subgroup of pathology was found to be completely resistant to anaesthesia by EMLA. CONCLUSION: We recommend the use of EMLA as a sole anaesthetic in small mucosal biopsies and shavings in all patients. We suggest it as a higher and first line recommendation for anaesthesia in needle phobic patients and children.

Level of Evidence Analysis in Journal of Maxillofacial Oral Surgery: A Twelve-Year Bibliometric Analysis of 1300 Publications (2009-2020).

AIM: Analysing Level of Evidence (LOE) provides an insight to evidence-based medicine (EBM). The aim of our study was to evaluate and analyse trends in Levels of Evidence (LOE) in Journal of Maxillofacial and Oral Surgery (MAOS) since inception, i.e. December 2009 along with categorization into subtopics. METHODOLOGY: LOE for each article was determined according to modified American Society of Plastic Surgeons (ASPS) scale and National Health and Medical Research Council (NHMRC) Evidence Hierarchy. RESULTS: A total of 1264 articles were included in the final analysis, out of which high-quality evidence (Level A) accounted for 7% of the journal. The percentage of Level I/II (Level A) has increased from 2.09% in 2009/2010 to 12.74% in 2019/2020, representing a promising trend toward higher-quality research in just 10 years. Case reports and narrative reviews with Level of Evidence value "D" account the highest number (36%) of all the published articles. The majority of articles fell under Class 2 (Maxillofacial pathology) classification (35%) highlighting myriad of articles covering pathologies and various reconstruction methods, followed by trauma (16%). CONCLUSION: The status of LOE and categorizing of published articles are the first step to audit and quantify the nature of literature published by JMOS and may further help in refining the quality of research jointly by the researchers and the editorial board.

Efficacy of adjuvant ozone therapy in reducing postsurgical complications following impacted mandibular third-molar surgery: A systematic review and meta-analysis.

BACKGROUND: Results from several randomized controlled trials have shown a beneficial effect of ozone in reducing postsurgical complications after impacted mandibular third-molar surgery, but the literature is lacking a systematic review and meta-analysis. METHODS: The authors conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines after exclusion and inclusion criteria were applied and the following outcome parameters were evaluated: pain, swelling, trismus, quality of life, number of analgesics consumed, and adverse events. RevMan Cochrane Collaboration software, Version 5.3, was used to perform meta-analysis and the Grading of Recommendation Assessment, Development and Evaluation approach was used to rate the certainty of evidence. RESULTS: Patients who underwent adjuvant ozone application reported lower pain scores than patients in the control group at 24 hours after surgery (95% CI, -3.94 to -1.56) and at 7 days (95% CI, -1.67 to -0.78). Pooled analysis of all 4 included trials revealed a standardized mean difference (SMD) in swelling of -0.44 at 24 hours, 0.63 at 72 hours, and -0.87 at 7 days after surgery in the experimental group. Higher mean estimates in mouth opening were experienced by patients who received ozone at 24 hours (SMD, 2.74; 95% CI, -1.93 to 7.41; 4 studies, 133 patients), 72 hours (SMD, 2.77; 95% CI, -0.63 to 6.17; 4 studies, 133 patients), and 7 days after surgery (SMD, 1.42 SMD; 95% CI, -1.34 to 4.18; 4 studies, 133 patients). PRACTICAL IMPLICATIONS: Evidence suggests that adjuvant ozone application can offer some benefit for reducing pain, improving quality of life, and decreasing mean intake of analgesics after impacted mandibular third-molar surgery, but it is not effective in reducing facial swelling and trismus, which paves the way for future research.
