Abstract
Oral submucous fibrosis (OSF) is a chronic progressive disease associated with increased collagen deposition and TGF-β1 release. The current therapy and management have been a limited success due to low efficacy and adverse drug reactions. This study aimed to evaluate epigallocatechin 3-gallate (EGCG) encapsulated nanoparticles loaded mucoadhesive hydrogel nanocomposite (HNC) for OSF. Developed HNC formulations were evaluated for their permeation behaviour using in vitro as well as ex vivo studies, followed by evaluation of efficacy and safety by in vivo studies using areca nut extract-induced OSF in rats. The disease condition in OSF-induced rats was assessed by mouth-opening and biochemical markers. The optimized polymeric nanoparticles exhibited the required particle size (162.93 ± 13.81 nm), positive zeta potential (22.50 ± 2.94 mV) with better mucoadhesive strength (0.40 ± 0.002 N), and faster permeation due to interactions of the positively charged surface with the negatively charged buccal mucosal membrane. HNC significantly improved disease conditions by reducing TGF-β1 and collagen concentration without showing toxicity and reverting the fibroid buccal mucosa to normal. Hence, the optimized formulation can be further tested to develop a clinically alternate therapeutic strategy for OSF.

Pal S, Sharma D, Yadav NP. Plant leads for mitigation of oral submucous fibrosis: Current scenario and future prospect. Oral Dis 2024; 30:80-99. [PMID: 36565439 DOI: 10.1111/odi.14485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/25/2022] [Accepted: 12/20/2022] [Indexed: 12/25/2022]
Abstract
The aim of this review is to enumerate medicinal plants and their bioactive compounds that may become potential leads in the mitigation of oral submucous fibrosis (OSMF) in the forthcoming future. It is focused on pathophysiology, risk factors, current treatment regimen, potential plant leads, and future therapies for OSMF. Data were extracted from a vast literature survey by using SciFinder, Web of Science, Google Scholar, and PubMed search engines with relevant keywords. Upon literature survey, we found that the phytochemical 'arecoline' present in the areca nut is the main causative agent of OSMF condition. Currently, OSMF is treated by immunomodulatory and anti-inflammatory agents such as corticosteroids, enzymes (hyaluronidase, chymotrypsin, and collagenase), anti-inflammatory mediators (isoxsuprine and pentoxifylline), dietary supplements (vitamins, antioxidants, and micronutrients), and anti-fibrotic cytokines like interferon-gamma that provides short-term symptomatic relief to OSMF patients. However, some plant leads have been proven effective in alleviating symptoms and mitigating OSMF, which ultimately improves the quality of OSMF patients' life. We concluded that plant drugs like lycopene, curcumin, Aloe vera, colchicine, and Glycyrrhiza glabra are effective against OSMF in various in vitro and/or clinical studies and are being used by modern and traditional practitioners.

Abstract
BACKGROUND Oral submucous fibrosis (OSF) is a chronic disease of the oral cavity that causes progressive constriction of the cheeks and mouth accompanied by severe pain and reduced mouth opening. OSF has a significant impact on eating and swallowing, affecting quality of life. There is an increased risk of oral malignancy in people with OSF. The main risk factor for OSF is areca nut chewing, and the mainstay of treatment has been behavioural interventions to support habit cessation. This review is an update of a version last published in 2008. OBJECTIVES To evaluate the benefits and harms of interventions for the management of oral submucous fibrosis. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 5 September 2022. SELECTION CRITERIA We considered randomised controlled trials (RCTs) of adults with a biopsy-confirmed diagnosis of OSF treated with systemic, locally delivered or topical drugs at any dosage, duration or delivery method compared against placebo or each other. We considered surgical procedures compared against other treatments or no active intervention. We also considered other interventions such as physiotherapy, ultrasound or alternative therapies. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were 1. participant-reported resumption of normal eating, chewing and speech; 2. change or improvement in maximal mouth opening (interincisal distance); 3. improvement in range of jaw movement; 4. change in severity of oral/mucosal burning pain/sensation; 5. ADVERSE EFFECTS Our secondary outcomes were 6. quality of life; 7. postoperative discomfort or pain as a result of the intervention; 8. participant satisfaction; 9. hospital admission; 10. direct costs of medication, hospital bed days and any associated inpatient costs for the surgical interventions. We used GRADE to assess certainty of evidence for each outcome. MAIN RESULTS We included 30 RCTs (2176 participants) in this updated review. We assessed one study at low risk of bias, five studies at unclear risk of bias and 24 studies at high risk of bias. We found diverse interventions, which we categorised according to putative mechanism of action. We present below our main findings for the comparison 'any intervention compared with placebo or no active treatment' (though most trials included habit cessation for all participants). Results for head-to-head comparisons of active interventions are presented in full in the main review. Any intervention versus placebo or no active treatment Participant-reported resumption of normal eating, chewing and speech No studies reported this outcome. Interincisal distance Antioxidants may increase mouth opening (indicated by interincisal distance (mm)) when measured at less than three months (mean difference (MD) 3.11 mm, 95% confidence interval (CI) 0.46 to 5.77; 2 studies, 520 participants; low-certainty evidence), and probably increase mouth opening slightly at three to six months (MD 8.83 mm, 95% CI 8.22 to 9.45; 3 studies, 620 participants; moderate-certainty evidence). Antioxidants may make no difference to interincisal distance at six-month follow-up or greater (MD -1.41 mm, 95% CI -5.74 to 2.92; 1 study, 90 participants; low-certainty evidence). Pentoxifylline may increase mouth opening slightly (MD 1.80 mm, 95% CI 1.02 to 2.58; 1 study, 106 participants; low-certainty evidence). However, it should be noted that these results are all less than 10 mm, which could be considered the minimal change that is meaningful to someone with oral submucous fibrosis. The evidence was very uncertain for all other interventions compared to placebo or no active treatment (intralesional dexamethasone injections, pentoxifylline, hydrocortisone plus hyaluronidase, physiotherapy). Burning sensation Antioxidants probably reduce burning sensation visual analogue scale (VAS) scores at less than three months (MD -30.92 mm, 95% CI -31.57 to -30.27; 1 study, 400 participants; moderate-certainty evidence), at three to six months (MD -70.82 mm, 95% CI -94.39 to -47.25; 2 studies, 500 participants; moderate-certainty evidence) and at more than six months (MD -27.60 mm, 95% CI -36.21 to -18.99; 1 study, 90 participants; moderate-certainty evidence). The evidence was very uncertain for the other interventions that were compared to placebo and measured burning sensation (intralesional dexamethasone, vasodilators). Adverse effects Fifteen studies reported adverse effects as an outcome. Six of these studies found no adverse effects. One study evaluating abdominal dermal fat graft reported serious adverse effects resulting in prolonged hospital stay for 3/30 participants. There were mild and transient general adverse effects to systemic drugs, such as dyspepsia, abdominal pain and bloating, gastritis and nausea, in studies evaluating vasodilators and antioxidants in particular. AUTHORS' CONCLUSIONS We found moderate-certainty evidence that antioxidants administered systemically probably improve mouth opening slightly at three to six months and improve burning sensation VAS scores up to and beyond six months. We found only low/very low-certainty evidence for all other comparisons and outcomes. There was insufficient evidence to make an informed judgement about potential adverse effects associated with any of these treatments. There was insufficient evidence to support or refute the effectiveness of the other interventions tested. High-quality, adequately powered intervention trials with a low risk of bias that compare biologically plausible treatments for OSF are needed. It is important that relevant participant-reported outcomes are evaluated.

Indian J Otolaryngol Head Neck Surg 2023; 75:3530-3534. [PMID: 37974777 PMCID: PMC10646069 DOI: 10.1007/s12070-023-04016-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 06/21/2023] [Indexed: 11/19/2023] Open
Abstract
AIM The present study aimed to compare the effectiveness of intralesional placentrex versus hyaluronidase + dexamethasone injection in the symptomatic management of stage II OSMF. MATERIALS AND METHODS This was a non-randomized prospective study conducted over a period of 14 months at a tertiary referral center. Patients with clinical stage II OSMF were randomly grouped into A(n = 18) and B(n = 17). These patients were treated with weekly intralesional injection of placentrex and hyaluronidase + dexamethasone respectively, over a period of six weeks. Variables such as mouth opening, burning sensation and colour of mucosa were evaluated at baseline(T0), second week(T1), fourth week(T3), sixth week(T4) of follow up. A p-value < 0.05 was considered statistically significant. RESULTS A total of 15 patients completed the study in each group with regular follow up. The mean improvement in mouth opening was 4.3 ± 0.57 mms in group A(p-value < 0.001) and 7.2 ± 0.76 mms in group B(p-value < 0.001) which were significant at the end of six weeks. Mean change in burning sensation at the end of six weeks in group A was 1.2 ± 0.73(p-value < 0.001), and 3.6 ± 0.63(p-value < 0.001) in group B. Mean change in colour of mucosa at the end of six weeks was 1.4 in group A(p-value > 0.05) and 2 in group B(p-value > 0.05). On comparison between both groups, patients in group B exhibited better mouth opening and reduction of burning sensation than patients in group A(p-value < 0.001). CONCLUSION Both intralesional placentrex and hyaluronidase + dexamethasone injection are effective in alleviating the symptoms of stage II OSMF. However, hyaluronidase + dexamethasone injection showed slightly better improvement in mouth opening and burning sensation after six weeks.

Abstract
Oral submucous fibrosis (OSMF) is a precancerous disorder of the submucosa that causes inflammation and progressive fibrosis, leading to pronounced stiffness and trismus. Chewing betel nuts is a significant risk factor for OSMF in India. Arecoline from betel nuts and copper, which causes fibroblast dysfunction and the development of fibrotic bands, are the main components of betel quid. OSMF is distinguished by fibrosis in the submucosal region, which affects the majority of the oral cavity and results in advanced lockjaw due to rigidity in the lips, pharynx, cheeks, and upper third of the oesophageal canal, which progresses to dysphagia. The prevalence of OSMF is rising, particularly among younger generations, as more commercially available areca nut products like gutka (chewing tobacco) and others are being introduced. The severity of OSMF develops as the practice continues and is permanent. It also persists even after chewing has been stopped. The hallmark of oral submucous fibrosis (OSF) is abnormal collagen deposition. It is a precancerous condition and progresses to malignant tumours. Symptoms include ulcers, xerostomia, submucous fibrosis, burning sensation, and a reduction in mouth opening. Each of these drastically reduces the patient's quality of life. In the past, many treatment modalities have been tried but none of them has resulted in a cure for the disease. The primary focus of the treatment is to reduce the signs and symptoms so that the patient can have a better quality of life. Along with principles, conservative, medical, and surgical management issues have also been covered.

Abstract
Oral submucous fibrosis (OSMF) is a chronic, progressive, insidious premalignant disease with multifactorial etiology affecting any part of the oral cavity and sometimes the pharynx by triggering a rapid onset of trismus and dysphagia due to stiffness at the lips, cheek, pharynx, and upper oesophageal region. Submucous fibrosis resembles many auto-immune, dermatological, mucocutaneous, and fibrotic lesions that include scleroderma, amyloidosis, iron deficiency anemia, and systemic or generalized fibromatosis clinically and histologically. Several authors established an association between oral submucous fibrosis and scleroderma with predominant oral manifestations on the basis of similarity in clinical and histological characteristics despite different pathogenesis and prognostic aspects. Scleroderma or systemic sclerosis is an autoimmune connective tissue disorder clinically manifested as fibrosis of the skin, blood vessels, and visceral organs with or without the involvement of the oral cavity. Thus, understanding the disease mechanism, appropriate early diagnosis, and clinical management of these two entities play an important role in disease prognosis and treatment outcomes. The present review was carried out to briefly present a concise overview of the etiopathogenesis, clinical, histological, diagnosis, and management aspects of OSMF and scleroderma based on the available literature, with special emphasis on similarities and differences between these two entities subsequently aiding in appropriate treatment planning.

Abstract
Introduction: Oral submucous fibrosis (OSMF) is a chronic premalignant condition and is characterized by fibroblastic change of lamina propria and stiffness of oral mucosa. Though there are several treatment options available, the best agent is not yet identified. This study assessed the comparative efficacy and safety of medical interventions in the management of OSMF. Methods: A systematic review was performed to identify randomized controlled trials (RCTs) that compared the efficacy of interventions for OSMF with each other, or placebo. A network meta-analysis was performed, and the interventions were ranked according to their efficacy based on the surface under the cumulative ranking. (PROSPERO Registration no: CRD42021255094). Results: Thirty-two RCTs comprising 2063 patients were eligible for quantitative analysis. In terms of therapeutic efficacy in the improvement of mouth opening Oxitard, a herbal formulation was ranked as the most efficacious agent, [MD, 10.29 (95%CI 6.34–14.25)] followed by combination therapy of Lycopene with corticosteroids and hyaluronidase [MD, 7.07 (95%CI 1.82–12.31)]. For improvement of burning sensation aloe vera was ranked first [MD, 6.14 (95%CI 4.58–7.70)] followed by corticosteroids with antioxidants [MD, 6.13 (95%CI 4.12–8.14)] and corticosteroids in combination with hyaluronidase with antioxidants [MD, 5.95 (95%CI 3.79–8.11)]. In terms of safety, most of the drugs were reported to cause mild adverse effects only. Significant inconsistencies could be identified in the analysis for both the outcomes assessed and were further explored. Conclusions: Our study highlighted the potential efficacy of several agents over placebo in the improvement of mouth opening and burning sensation in OSMF patients. However, the RCTs lacked methodological soundness. Well-designed studies with a larger number of participants with a rigorous randomization process and stringent methodology are recommended to strengthen the results obtained, which may help to construct a clinical guideline for OSMF management.

Abstract
Background and aim: Oral Submucous Fibrosis (OSMF) is potentially pre-malignant condition of the oral cavity with a high malignant transformation rate. The condition not only affects the oral function of the patients but has a huge impact on their social and psychological wellbeing affecting the overall quality of life. To evaluate the effectivity of the treatment assessing the quality of the life of these patients before and after treatment is of utmost importance but till now has not been an integral part of the management strategy. This study was carried to assess the change in quality of life before and after treatment with curcumin in patients with OSMF. Methods: Quality of life was assessed before and after 3 months of treatment with topical curcumin in 50 patients with OSMF using European Organization for Research and Treatment of Cancer Quality of Life head and neck Questionnaire (EORTC QLQ35). Results: At the end of 3 months there was significant (p < 0.05) change in the quality of life of patients with OSMF as suggested by assessment of the multi-item and single item scale used in the questionnaire. Conclusion: The study emphasizes the use of assessing Quality of life as an integral part of treatment strategy for OSMF and suggests curcumin as a promising treatment modality for patients with OSMF.

Abstract
PURPOSE Coronoidectomy is carried out frequently as a part of the cranial-maxillofacial surgery procedure. There are few articles on the fate of coronoid process after coronoidectomy, except that several case reports mentioned that coronoid process had regenerated. This study aimed to radiographically access the anatomic outcomes of coronoid process and investigate which factors were associated with the outcomes after coronoidectomy. MATERIALS AND METHODS A retrospective cohort study included patients undergoing coronoidectomy over a 7-year period. The primary outcome variable was the new coronoid process occurrence (yes/no). Secondary outcome variable was the type of the new coronoid process by evaluating its size, shape and position. Radiograph at 1-year postoperative visit was used to determine the outcomes. The predictor variables included age, sex, surgical purpose, surgical side, surgical approach and the maximal interincisal opening. Appropriate statistics were analyzed by SPSS version 22. χ2 test and binary logistic regression were used to assess the association between predictor factors and anatomic outcomes (P <.05). RESULTS The study sample included 57 patients. In total, 96 coronoidectomies were performed. Seventy-four coronoid processes (77.1%) showed complete (n = 44, 45.8%), nonunion (n = 19, 19.8%) or partial (n = 11, 11.5%) regrowth, whereas no evidence of regeneration in 22 sites was observed radiographically at 1-year postoperative visit. Binary logistic regression showed that a young age (odds ratio 0.704; 95% confidence interval 0.562-0.882; P = .002) was significantly associated with regeneration of coronoid process. CONCLUSIONS Coronoid process can mostly regenerate after coronoidectomy. A young age may contribute to regrowth of coronoid process.

Abstract
Oral submucous fibrosis (OSF) is a precancerous condition of the oral cavity associated with habitual chewing of quid, with a high incidence among populations of the Indian subcontinent and Southeast Asia. Clinically, its initial manifestation may mimic oral lichen planus or lichen sclerosus. If the habit is not halted, the mucosa gets leathery and thickened, and fibrous bands form causing significant morbidity. Microscopically, it is characterized by atrophic epithelium, loss of rete ridges, and hyalinization of lamina propria. Of note, these hallmark histopathological features may be overlooked in the unusual presence of lichenoid interface changes, which may lead to the wrong diagnosis. We present herein five cases in which the rare joint appearance of OSF and lichenoid reaction features posed a diagnostic challenge. Due to its progressive nature and malignant potential, the presence of oral lichenoid changes overlying submucous hyalinization, in the right clinical and demographic setting, should raise suspicion of OSF and prompt actions directed at quid-chewing discontinuation.

Abstract
Oral submacosal fibrosis (OSF) has been recognized as one of the oral potentially malignant disorders. Areca nut chewing is implicated in this pathological fibrosis. The current treatments for OSF have failed to achieve the desired curative effect. Here, we propose that curcumin has excellent therapeutic effect on OSF and explore its specific mechanism. Transwell assay was performed to detected cell migration. Flow cytometry was used to measured apoptosis. And MTT assay was performed to test cell viability. Gene and protein levels were detected by quantitative real-time polymerase chain reaction (qPCR) and western blotting. Our results displayed that curcumin treatment reduced fibrosis-related molecules (collagen type I alpha 1, collagen type III alpha 1, tissue inhibitor of metalloprotease 2) in arecoline-treated oral mucosal fibroblasts and elevated matrix metalloproteinase 2 expression. Additionally, curcumin could suppress cell proliferation and migration, and enhance the apoptosis of arecoline-treated normal oral mucosal fibroblasts. Most importantly, the hypoxia-inducible factor-1α (HIF-1α), transforming growth factor-β (TGF-β) and connective tissue growth factor (CTGF) expressions in arecoline-treated normal oral mucosal fibroblasts were reduced after exposure to curcumin, whereas the activation of HIF-1α/TGF-β/CTGF axis reversed curcumin's effect on improving fibrosis of arecoline-treated normal oral mucosal fibroblasts. Therefore, curcumin alleviated oral submucosal fibrosis via inhibiting HIF-1α/TGF-β/CTGF axis. In summary, curcumin effectively inhibited the migration and proliferation and promoted apoptosis in arecoline-induced normal oral mucosal fibroblasts by inactivating HIF-1α/TGF-β/CTGF pathway. And curcumin might be a potential therapeutic drug for OSF treatment.

Efficacy of collagen-silicone bilayer membrane in the management of oral submucous fibrosis: a prospective case series. Oral Maxillofac Surg 2021; 26:73-79. [PMID: 33866454 DOI: 10.1007/s10006-021-00962-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 04/12/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND AND OBJECTIVE Oral submucous fibrosis is a scourge of Southeastern Asia since a long time resulting in significant health and social problems. Mainstay of the treatment is concentrated on attempts to improve mouth opening and relieve the symptoms by medicinal or surgical means. In moderate to severe cases, release of fibrous bands is advocated followed by placement of graft. The present study was conducted to evaluate the use of collagen-silicone bilayer membrane as a mucosal substitute in its management. METHODOLOGY Study consisted of 12 clinically and histologically proven cases of OSMF. After the incision and release of fibrous bands, a collagen membrane was placed and secured over the raw area by placement of a silicone sheet of adequate thickness. Parameters were assessed pre-operatively, intra-operatively, and post-operatively at 1 week, 1 month, and 3 months. The data was recorded and statistical analysis was done. RESULTS Pre-operatively, the mean values of inter-incisal opening, cheek flexibility, and width of oral commissure were 16.92, 24.58, and 53.17 mm respectively whereas at 3 months post-operatively, it was 27.67, 26.58, and 55.00 mm, which was statistically significant. No incidence of infection was noted. CONCLUSION The study concludes that the use of collagen membrane along with silicone sheet can be an alternative to other graft materials in context of reduced donor site morbidity as well as significant increase in inter-incisal opening. However, study with more sample size is needed to assess the long-term efficiency and surgical outcome of this material.

Abstract
During oral pathology daily practice, true amyloid may be identified in oral amyloidosis and several odontogenic tumors. However, histologic examination often reveals other oral and perioral diseases with similar eosinophilic, acellular, amorphous substances. These include extensive areas of collagenous sclerosis, fibrin deposition, elastic fiber degeneration, and dentinoid material, which may resemble amyloid under light microscopic examination. These materials are often termed "amyloid-like" due to their close histologic resemblance to true amyloid. The rarity of most of these conditions and their strong histologic similarity may hamper an accurate diagnosis. Definitive diagnosis of these lesions may require clinical correlation; laboratory evaluation; histochemical or immunohistochemical reactions; and, in some cases, genetic investigation. In this review, we describe the main clinicopathologic features of this group of diseases that may manifest in the oral and/or perioral regions and that have in common the presence of amyloid-like material deposition.

Abstract
INTRODUCTION Oral submucous fibrosis (OSMF) is a potentially malignant disorder with a high rate of malignant transformation. It is associated with chewing of areca nut and tobacco products with a high global prevalence, particularly in the southeast Asian countries. A wide range of treatment modalities are available, ranging from corticosteroids, antioxidants, nutritional supplements to herbal medicines but lacks a reliable treatment regimen. AIM This systematic review will comprehensively analyze the medicinal treatment for OSMF from 2011 to 2020, apprise the literature with new clinical studies, and initiate a discussion about other potential medicines. MATERIAL AND METHODS A comprehensive electronic search was conducted in Pubmed, Scopus, and other databases from January 2011 to June 2020 according to the PRISMA guidelines, to identify all the clinical studies for the medicinal management of OSMF with definite keywords and defined criteria. RESULTS Among the thirty-two included clinical studies 23 were randomized controlled studies and 9 were case-control studies. The treatment outcomes were diverse, and the majority of the studies showed improvement in the subjective signs and symptoms of OSMF. Only a few studies noticed the side effects. CONCLUSION No single treatment modality is effective in the management of OSMF. The concurrent use of triple therapy is efficacious. The naturally occurring herbal medicines have an immense potential in the management of OSMF. Therefore, high-quality, longitudinal, multi-center randomized controlled trials with larger samples need to be conducted to further assess the efficacy of various medicinal formulations in conjunction with physiotherapy in the management of OSMF.

Abstract
BACKGROUND Long-term follow-ups after receiving lycopene therapy for management of oral submucous fibrosis (OSMF) are scarce. The study aimed to assess the long-term efficacy of lycopene for management of OSMF symptoms. METHODS In this prospective clinical study, 400 clinically diagnosed early OSMF patients were assessed for the efficacy of lycopene in alleviation of burning sensation (BS) and reduced mouth opening (MO) symptoms in comparison to placebo. After 1-year follow-up, group A (lycopene group) was divided equally into group A1 and group A2. group A1 patients were retreated with lycopene and the A2 group was followed without retreatment. After 2-year follow-up, the Group A2 patients were advised retreatment but not followed as most of the patient did not agree for follow-up. However, group A1 patients were continued to follow-up every 6 months for a total three years. Statistical analysis was by independent sample t-test and P-value <.05 were considered as significant. RESULTS A statistically significant difference (P < .05) in BS and MO was found between group A and B with lycopene showing better results. At one-year follow-up, a statistically significant recurrence in the symptoms was found (P < .05) in the lycopene group (group A). After the second intervention, there was a statistically significant difference in the improvement of symptoms between the group A1 and A2 at 6 months and 1 year (P < .05) with group A1 (retreatment) showing better results. CONCLUSIONS Treatment with lycopene led to improvement in the symptoms of OSMF in the present study. The results highlight the importance of retreatment of lycopene for its long-term effect on alleviation the symptoms of OSMF.

Abstract
Oral Submucous fibrosis (OSMF) has traditionally been described as “a chronic, insidious, scarring disease of the oral cavity, often with involvement of the pharynx and the upper esophagus”. Millions of individuals are affected, especially in South and South East Asian countries. The main risk factor is areca nut chewing. Due to its high morbidity and high malignant transformation rate, constant efforts have been made to develop effective management. Despite this, there have been no significant improvements in prognosis for decades. This expert opinion paper updates the literature and provides a critique of diagnostic and therapeutic pitfalls common in developing countries and of deficiencies in management. An inter-professional model is proposed to avoid these pitfalls and to reduce these deficiencies.

Abstract
The aim of the study was to evaluate the effectiveness of seagull-shaped nasolabial flap (NLF) along with adjunctive short-term oral pentoxifylline in the surgical reconstruction of oral sub mucous fibrosis (OSMF) following fibrotomy. We retrospectively evaluated 18 patients with grade IV oral sub mucous fibrosis treated by NLF. There were 3 females and 15 males. All patients were classified as stage IV OSMF with a mean preoperative mouth opening of 8.11±3.38mm. Postoperatively, patients were administered 400mg of pentoxifylline (PTX) thrice daily for 3 months. Patients were followed up at one month, six months and one year. Mouth opening, presence or absence of malignant transformation, relapse and complications were recorded at each follow-up. We found statistically significant increase in mouth opening from 8.11±3.3 to 37.67±3.74 in the postoperative period. The complications associated with NLF were very minimal. The PTX was well tolerated by all the patients. There was no incidence of relapse or rebound fibrosis seen in our series. To the best of our knowledge, this is the first time that oral pentoxifylline has been administered along with surgical treatment of oral submucous fibrosis to prevent relapse. The use of oral PTX as an adjunct along with surgical reconstruction in OSMF improves mouth opening, reduces burning sensation and relapse.

Potentially malignant disorders of the oral cavity and oral dysplasia: A systematic review and meta-analysis of malignant transformation rate by subtype. Head Neck 2019; 42:539-555. [PMID: 31803979 DOI: 10.1002/hed.26006] [Citation(s) in RCA: 220] [Impact Index Per Article: 44.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 10/14/2019] [Accepted: 10/18/2019] [Indexed: 12/11/2022] Open
Abstract
IMPORTANCE Potentially malignant disorders of the oral cavity (OPMD) are a heterogeneous group of lesions associated with a variable risk of malignant transformation (MT) to invasive cancer. Leukoplakia (LE), lichen planus (LP), oral lichenoid lesions (OLL), oral erythroplakia (OE), oral submucous fibrosis (OSF), and proliferative verrucous leukoplakia (PVL) are among the most common of these lesions. Oral dysplasia is a mucosal area characterized by cellular and architectural derangement, which may be associated with OPMDs or not. OBJECTIVE To define the MT rate of OPMDs and the risk of development into cancer of mild vs moderate/severe oral dysplasia. This in order to implement adequate follow-up strategies and treatment decisions. STUDY DESIGN We performed a systematic review and meta-analysis on studies reporting the MT rates of OPMDs and oral dysplasia. Ninety-two studies were included for the analysis. Cumulative rates were reported for OPMDs overall and as a subgroup, a comparison was made of mild vs moderate/severe dysplasia. Meta-regression on OPMD and year of publication was also performed. MAIN OUTCOME AND MEASURES Overall MT rates of OPMDs and odds ratio of MT of mild vs moderate/severe dysplasia. RESULTS Overall MT rate across all OPMD groups was 7.9% (99% confidence interval [CI] 4.9%-11.5%). MT rates of the specific OPMD subgroups were as follows: LP 1.4% (99% CI 0.9%-1.9%), LE 9.5 (5.9%-14.00%), OLL 3.8% (99% CI 1.6%-7.00%), OSF 5.2% (99% CI 2.9%-8.00%), OE 33.1% (99% CI 13.6%-56.1%), and PVL 49.5% (99% CI 26.7%-72.4%). Regarding the dysplasia grades comparison, the meta-analysis showed that moderate/severe dysplasia is meaningfully associated to a much greater risk of MT compared to mild dysplasia with an odds ratio of 2.4 (95% CI 1.5-3.8) [Correction added on 27 December 2019, after first online publication: CI updated from 99% to 95%.]. Heterogeneity was not significant. Annual MT rates were approximated based on the average follow-up as reported in the various subgroups. Lichen planus had an annual MT of 0.28%, OLL of 0.57%, leukoplakia of 1.56%, PVL of 9.3%, and OSF of 0.98%. Mild dysplasia had an annual MT of 1.7%, while severe dysplasia of 3.57%. Meta-regression showed a significant negative correlation of PVL MT rate and year of the study (P value <.001). CONCLUSIONS AND RELEVANCE OPMDs and oral dysplasia are relatively common conditions that general practitioners, head and neck, and oral medicine specialists, face in their everyday practice. Our analysis confirms the significant risk of MT of these lesions, although variable among the subgroups. Moderate/severe dysplasia bears a much higher risk of cancer evolution than mild dysplasia. It is important to raise public health awareness on the MT rates of these conditions, at the same time efficacious communication with the patient is of utmost importance. This, coupled with strict follow-up measures and optimal treatment strategies, would help in reducing the transformation of these oral conditions into invasive cancer.

Abstract
OBJECTIVES Oral submucous fibrosis (OSF) is a chronic debilitating disease that has a high risk of malignant transformation. Management of OSF is quite challenging, with no definitive cure being available. This systematic review assessed the available evidence for using curcumin for pain alleviation and clinical improvement in patients with OSF. STUDY DESIGN A comprehensive search of PubMed/Medline, Scopus, and ISI Web of Science databases was conducted to identify all relevant clinical trials comparing patients receiving curcumin treatment to active and/or nonactive controls for the treatment of OSF. RESULTS Six clinical trials comprising 298 patients were included. All studies found curcumin to be effective in the management of OSF. Three studies found significantly higher improvement in burning sensation in the curcumin group compared with controls, whereas 3 other studies found comparable results. With regard to clinical signs, 2 studies showed better improvement in mouth opening in the curcumin group; 3 studies reported no differences in effectiveness; and only 1 study found curcumin to be inferior to conventional therapy. CONCLUSIONS The available evidence remains inconclusive but suggests that curcumin is a promising effective treatment option for the management of patients with OSF. Further well-designed clinical trials with large sample sizes and adequate follow-up periods are warranted.

Buccal Mucosal Epithelial Cells Downregulate CTGF Expression in Buccal Submucosal Fibrosis Fibroblasts. J Maxillofac Oral Surg 2017; 17:254-259. [PMID: 29618895 DOI: 10.1007/s12663-017-1056-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Accepted: 11/14/2017] [Indexed: 01/01/2023] Open
Abstract
Introduction Oral submucosal fibrosis (OSMF) is a chronic debilitating fibrotic disease of the oral cavity and is a serious health hazard in south Asia and, increasingly, the rest of the world. The molecular basis behind various treatment modalities to treat OSMF still remains unclear. In this study, we have investigated the in vitro ability of the buccal mucosal cells to reduce the proliferation of the fibroblasts of the fibrotic area in co-culture of cells and also at the molecular levels to reduce the level of connective tissue growth factor (CTGF) in the OSMF fibroblasts (SMF-F). Materials and Methods The study compares isolation, morphological and proliferation kinetics of SMF-F and BMF cells with and without co-culturing with BMEs. In addition, we have compared the mRNA expression levels of CTGF in SMF-F co-cultured BME and non-co-cultured SMF-F cells using validated real-time quantitative PCR (RT-qPCR) method. Results The basic morphological characteristics of SMF-F were similar to BMF, but the former cells had higher proliferation rate in early passages compared to late passage state. We also observed that the CTGF expression levels in SMF-F under co-culture conditions of BME were consistently and significantly downregulated in all four different SMF-F-derived cells from four different patients. Conclusion Rapid proliferation and collagen synthesis in SMF-F as against BMF cells are the factors that confirm the innate nature of fibrosis fibroblasts (SMF-F). Further, the CTGF expression level in SMF-F was significantly suppressed by BME in co-culture conditions against controls (BMF). Considered together, this suggests that the cell therapeutic candidate of BME could be used in treating OSMF.
