RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Objectives: To determine the frequency of orthodontic emergencies and their impact on the treatment progress caused by delayed appointments due to the lockdown during the COVID-19 pandemic. Materials and methods: Two hundred thirty-eight patients undergoing fixed orthodontic treatment participated in this cross-sectional study. A pre-structured questionnaire was divided into six parts (Part A-C comprised of orthodontic emergencies and Part D-F comprised of various adverse effects and impacts on treatment progress). Two specialist orthodontists performed clinical examinations to complete the questionnaire. The final data were expressed as frequency and percentage. Results: Maximum number of patients reported four months after lockdown. Nearly half of the patients reported debonding of at least one of the brackets. Loosening of molar bands and debonding of second molar tubes were observed in 12.6% and 18.9% of patients, respectively. Ligation method failures were reported in 41.2% of the patients. Patients fitted with transpalatal arch/lingual arch skeletal anchorage showed a failure rate of 26.1% and 10%, respectively. Almost 29% of the patient complained of discomfort due to distal wire impingement. Undesired tooth movements were seen in almost 25% of patients. Alignment, space closure, and settling of occlusion were affected in 47.6%, 17.4%, and 35.7% of patients, respectively. Conclusions: This study helps to determine various types of adverse effects that can occur due to delayed appointments. The study's outcomes suggest that clinicians should be prepared to deal with future pandemics or other causes that might lead to delayed appointments.

RESUMO

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.

RESUMO

COVID-19 is a relatively new disease whose complete pathogenesis and complications have not been elucidated. Apart from the morbidity and mortality caused by the virus itself, it is noted that patients affected with this virus have a higher susceptibility to bacterial and fungal co-infections. Mucormycosis is a rare and life-threatening fungal infection generally associated with uncontrolled diabetes mellitus and immunosuppression. It tends to rapid disease progression and poor prognosis if not diagnosed and managed promptly. There has been a sudden increase in the number of mucormycosis cases in patients with moderate to severe COVID-19 infection in the past few months. Herein, we present a series of 10 mucormycosis cases diagnosed over one week.

RESUMO

Purpose and Objectives: One of the main causes of the increasing oral cancer (OC) burden in India is a lack of awareness and a significant gap in knowledge about risk factors and symptomology of OC. Materials and Methods: A questionnaire-based cross-sectional study was to evaluate the knowledge and awareness about OC among 500 random patients presenting for care at a tertiary hospital in western Rajasthan which serves a wide area of western, northern, and central Rajasthan. Results: A total of 446 participants, among which 83.6% were males enrolled in the study. Much to our despair, the results showed 35.23% of the participants (P = 0.007) started their habit at age <15 years. Nearly 60.3% of the participants were well aware of the harmful temporary or permanent effects of the tobacco. Around 40.85% of the participants taking tobacco products were ignorant about their changes in the tissues (site of tobacco placement). TV and Radio (50.5%) were the main source of information of the ill effects of tobacco and form a major contribution in public awareness. More than 90% of the participants had read the warnings on the tobacco packets. No doubt participants have knowledge about the ill effects of tobacco still there was a lack in behavioral modifications for tobacco cessation, leading to nonsuccess in quitting, with actual nonunderstanding about the ill effects of tobacco and overall lack of belief in the tobacco control measures. Conclusion: Our findings have found a gap in the awareness efforts of OC for the general population and will make public health professionals, clinicians, policymakers, and government a better judge and motivate them to strengthen existing national tobacco control efforts.

RESUMO

Aim: MicroRNAs have been widely acknowledged as a diagnostic, prognostic, and/or therapeutic biomarker for the progression of OSCC, but the correlation of hsa-miR-101-5p and hsa-miR-155-3p is yet to be established with c-Fos in OSCC and OSMF. Methodology: An observational study enrolled 40 patients divided into 2 groups: Group I-21 OSMF patients without malignant transformation, Group II-19 patients with locally advanced, large-operable, or metastatic OSCC, after applying inclusion and exclusion criteria. Both miRNAs were extracted and analyzed from the tissue sample excised from the involved site. The linear regression analysis of the expression of hsa-miR-155-3p, hsa-miR-101-5p, and levels of c-fos in OSMF and OSCC patients and its correlation for habits, age, and gender were evaluated. Results: The expression of hsa-miR-101-5p was 0.81 times downregulated in OSCC tissue compared to OSMF, whereas hsa-miR-155-3p and c-fos were both upregulated 9.30 times and 1.75 times, respectively, in OSCC tissue. In Gutkha and tobacco chewers, the hsa-miR-155-3p expression could explain 12.3% (p = 0.031) for Gutkha chewers, whereas c-fos could explain 38.6% of the cases (p = 0.020) for tobacco chewers. The expression of hsa-miR-101-5p and hsa-miR-155-3p explained 43.7% and 59.5% of OSCC cases in alcoholics, respectively. Interestingly, in non-alcoholics, hsa-miR-155-3p and hsa-miR-101-5p were significant predictors of OSCC. Conclusion: Downregulation of tumor-suppressor hsa-miR-101-5p and upregulation of proto-onco hsa-miR-155-3p is responsible for intricate regulation of the progression of OSMF to OSCC via deregulated expression of c-Fos and tobacco chewing and advancing age is significant contributors for OSCC.

RESUMO

Cold Atmospheric Pressure (CAP) plasma has shown successful antibacterial efficacy in different medical applications which have prompted researchers to explore its possible use in endodontics. The aim of the present study was to comparatively evaluate the disinfection effectiveness of CAP Plasma jet with 5.25% sodium hypochlorite (NaOCl) and Qmix in Enterococcus Faecalis infected root canals at different time intervals (2, 5, and 10 min). 210 single-rooted mandibular premolars were chemomechanically prepared and infected with E. faecalis. The test samples were exposed to CAP Plasma jet, 5.25% NaOCl, and Qmix for 2, 5, and 10 min. The residual bacteria from the root canals if any were collected and evaluated for colony-forming units (CFUs) growth. ANOVA and Tukey's tests were used to evaluate the significant difference between treatment groups. 5.25% NaOCl showed significantly more antibacterial effectiveness (<0.001) when compared with all other test groups except Qmix at 2 and 10 min of exposure time. A minimum contact time of 5 min with 5.25% NaOCl is recommended to get zero bacterial growth in E. faecalis infected root canals. QMix requires a minimum contact time of 10 min to achieve optimal CFUs reduction and CAP plasma jet requires a minimum contact time of 5 min to achieve substantial CFUs reduction.

RESUMO

OBJECTIVE: To compare rate and anchorage loss during en-masse retraction of anterior maxillary teeth between friction mechanics (FM) and frictionless mechanics (FLM). SETTING AND SAMPLE POPULATION: Thirty-eight patients requiring en-masse retraction of protruded anterior maxillary teeth were randomly allocated into FM and FLM groups. METHODS: En-masse retraction with sliding mechanics (FM) using an elastomeric chain was compared with continuous mushroom loop archwire mechanics (FLM). Study models and lateral cephalograms were taken before (T1) and immediately after retraction (T2). The primary outcome was the rate of en-masse retraction. Anchorage loss was the secondary outcome. Intergroup comparison was performed using an independent t test (P < .05). RESULTS: Baseline characteristics were similar between groups. Thirty-six patients completed the trial. Two patients were lost to follow-up in the FLM group. The rate of en-masse retraction did not differ significantly (P = .625) between FM (0.7 mm/mo) and FLM (0.8 mm/mo) groups. The intragroup comparison showed significant anchorage loss in FM (2.28 mm) and FLM (1.13 mm) groups; however, the intergroup comparison showed no statistically significant difference (P = .093). Maxillary first molar showed a statistically significant change in angulation between the two mechanic groups (P < .001). Vertical movement of the maxillary incisor and first molar showed no significant difference between FM and FLM groups (P = .143, P = .546, respectively). CONCLUSIONS: The rate of en-masse retraction and anchorage loss was comparable between the FM and FLM groups. Significant anchorage loss was seen with both mechanics. The result suggests that both the mechanic group require external reinforcement to prevent anchorage loss.

RESUMO

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.

RESUMO

Oral squamous cell carcinoma (OSCC) is one of the common types of cancer. Its progression follows a transition from oral potentially malignant disorders (OPMDs) such as oral submucous fibrosis (OSMF). Epigenetic modifiers, especially microRNAs (miRNAs), have an appreciable role in the regulation of various carcinogenic pathways which are being used as biomarkers. miRNAs may also be helpful in the differentiation of oral submucous fibrosis from oral squamous cell carcinoma. Three miRNAs, miR-221-3p, miR133a-3p, and miR-9-5p, were found differentially expressed in many cancers in the literature search supported by our preliminary database search-based screening. The literature and our functional enrichment analysis in an earlier study have reported these miRNAs to regulate carcinogenesis at various steps. In the present study, the expression of these miRNAs was examined in 34 histopathologically confirmed OSCC, 30 OSMF, and 29 control (healthy volunteers) human samples. There was a significant downregulation of miRNA-133a-3p in OSCC compared to OSMF and controls, whereas there was up-regulation in oral submucous fibrosis compared to controls. There was no significant difference in the expression of miR-221-3p between OSCC and OSMF, but an upregulation in OSCC compared to controls. miR-9-5p was also found upregulated in both OSCC and OSMF. Further, miR-133a-3p expression was negatively correlated with age, smoking, drinking status, and AJCC staging, whereas miR-9-5p expression was only positively associated with tobacco/ areca nut chewing. The ROC plots, logistic regression model generated, and the correlation between the expression of miR-9-5p and miR-133a-3p in blood and tissue suggests that these could be used as risk stratification biomarkers.

RESUMO

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.

RESUMO

Background: Even after the invention of the modern injection techniques, palatal injection still remains a painful experience for patients, and this pain is attributed to the presence of rich nerve complement and displacement of tightly adherent palatal mucosa during anesthesia. Aim: To check the clinical efficacy of EMLA as a topical anesthetic agent instead of palatal injection during maxillary dental extractions. Methodology: The trial includes a total of 102 participants, in whom maxillary molar extractions were indicated, were randomly divided into the experimental group (eutectic mixture of local anesthesia (EMLA) topical application was used along with buccal injection) and control group (palatal injection along with buccal injection). Pain perception during extraction was recorded using the visual analog scale (VAS). Results: Mean VAS score for 'injection' in control group patients was 5.2 ± 2.08 in contrast to no pain in experimental group. In experimental group, mean VAS score on 'probing' was 0.92 ± 1.50. VAS score on 'extraction' in EMLA group was little higher though the difference was not statistically significant. The overall experience using Liekert's scale was higher in experimental group (4.0 ± 0.76) as compared to (3.3 ± 0.82) in control group leading to higher overall satisfaction among patients who underwent extraction in the experimental group. Conclusion: EMLA application produced a satisfactory level of anesthesia in the palatal tissue when compared with the palatal injection.

RESUMO

BACKGROUND: We diagnosed various cases of rhino-orbital-cerebral- COVID-associated Mucormycosis (ROCM-CAM) during India's second wave of COVID-19. This helped formulate novel suggestions for improving laboratory output, applicable anywhere in the world. METHODS: To diagnose ROCM-CAM by microbiological methods, we used direct microscopy and conventional culture on various clinical samples within the shortest turn-around time. DESIGN: Prospective single-center observational study. PARTICIPANTS: Patients with ROCM-CAM. RESULTS: Of 113 suspected cases of ROCM-CAM during May 2021, direct microscopy and culture could confirm the disease in 87.61% and 44.25% of patients, respectively. The highest pathogen isolation was seen from maxillary bone fragments, FESS-guided biopsy from pterygopalatine fossae, nasal turbinates and nasal mucosal biopsy. Direct microscopy could diagnose the disease in almost 40% of patients within 24 hours and 60% within two days. Conventional cultures yielded Rhizopus spp. (86%) as the commonest fungal pathogen followed by Mucor spp. (12%) within 7 days. Deep tissue biopsies are more useful for rapid diagnosis than superficial specimens. Routine fungal cultures can supplement case detection and help prognosticate survivors. CONCLUSION: The management of ROCM is a surgical emergency. The diagnosis of the condition must therefore be prompt and precise. Despite ongoing antifungal therapy, nasal mucosal tissue, FESSguided, and intra-operative tissue biopsies showed the pathogen's highest diagnostic yield. The diagnostic index improved further when multiple (4-5) high-quality specimens were collected. Nasal swabs and crusts, among the most commonly requested specimens worldwide, were found to have an overall low diagnostic potential.

RESUMO

ABSTRACTS: Aberrant methylation pattern leads to altered gene expression, that is, involved in the transformation of various cancers, including oral squamous cell carcinoma (OSCC). In the present study, an attempt has been made to examine the association of global and promoter-specific methylation of tumor suppressor genes in patients with OSCC and oral submucous fibrosis (OSMF). Promoter-specific methylation of tumor suppressor genes P16, SOCS1, and SHP1 had been studied earlier for their aberrant methylation patterns in other cancers; however, these studies were mainly conducted in-vitro or in animal models, and as such, only a few studies are available on human samples. In the present study evaluation of promoter-specific methylation of genes P16, SOCS1, and SHP1 in 76 patients' blood and tissue samples was done and compared with methylation of 35 healthy control samples using qPCR. Further, these samples were analyzed for global methylation patterns using ELISA. The results have shown a significant decreasing trend of promoter methylation (OSCC > OSMF > Controls); the methylation indices (MI) were significantly higher in OSCC than in the controls. The median MI of three genes for OSCC were P16MI (0.96), SHP1MI (0.79), and SOCS1 (0.80). Similarly, median MIs for OSMF were P16MI (0.18), SHP1 MI (0.19), and SOCS1 MI (0.5) against controls with MI (0) for each of the three genes. The global methylation %mC values were 1.9, 0.5, and 0.1, respectively. The values of MI and %mC were found to correlate with various risk factors such as tobacco, smoking, and alcohol consumption, which are positively involved in OSMF pathogenesis followed by oral cancer progression. Further, the methylation trend in tissue was reflected in blood samples, proving a window for methylation load to be used as a lesser invasive biomarker. The sensitivity and specificity of methylation load were also found reasonable. Therefore, the current study suggests that there may be a role of global and promoter-specific methylation load in the transition of OSMF to OSCC.

RESUMO

Mucosal melanoma is an exceedingly rare and aggressive neoplasm with high mortality rate. In contrast to the cutaneous melanomas, the risk factors and pathogenesis are poorly understood. It is predominantly localized in the region of the hard palate and maxillary alveolus. Surgery is the mainstay of treatment, but it may turn out to be challenging depending on the anatomic location, extent and size of the tumor and presence of metastasis. Presented here is a series of two cases of maxillary mucosal melanoma with varied presentation.

RESUMO

Context: The widely accepted caries risk assessment tools such as the Cariogram model needs modifications in the scoring of different factors for reliable results. Aims: The study was aimed to report the caries experience in 3-60 years of the Rajasthan population and to apply the newly derived average decayed exfoliated filled teeth/Decayed Missing Filled Teeth (deft/DMFT) scores in the Cariogram model to assess the caries risk. Settings and Design: The cross-sectional study was planned in the Department of Dentistry and a total of 500 participants were equally divided into five groups (3-6, 7-12, 13-30, 31-44, and 45-60 years) were included. Methods and Material: All participants were examined for caries detection using deft/DMFT, ICDAS, and CAST indices according to the predefined protocol. A single examiner evaluated the participants in a dental operatory and data was recorded. Statistical Analysis Used: One-Way ANOVA and Tukey's Post-Hoc tests were used to evaluate the significant difference between the groups of each caries index. Results: A statistically significant difference was observed between the mean deft/DMFT and CAST scores of 3-6, 7-12, and 13-30 age groups with the 45-60 years age group. Caries prevalence was highest (83%) in 31-44 and 45-60 year age groups and lowest (51%) in the 3-6 year age group. Conclusions: Caries experience scores increase as the age increases and the highest scores were observed in 31-44 and 45-60 year age groups and the lowest were observed in the 3-6 year age group. The average ICDAS and CAST scores were higher when compared to the deft/DMFT index.

RESUMO

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.

RESUMO

Introduction: Recurrent aphthous stomatitis (RAS) is one of the most common ulcerative diseases affecting the general population. The present study aimed to evaluate the clinical efficiency of 0.5% minocycline mouth rinse prescribed along with the topical anesthetic gel and vitamin supplement over the topical anesthetic gel and vitamin supplement prescribed alone for treating RAS. Materials and Methods: A total of 60 participants were randomly divided into two groups-experimental group: 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel; and control group: vitamin supplement and topical anesthetic gel alone. The pain symptoms were evaluated using the VAS scores at baseline and first follow-up visits. The data were analyzed using Student's t test. Results: A significant reduction in the pain scores was observed in participants using the 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel on the first follow-up visit (P = < 0.001). Conclusion: The 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel had shown more reduction in the pain symptoms when compared to topical anesthetic gel and vitamin supplement prescribed alone for the treatment of RAS.
