Comparison Of Efficacy Of Steroids Alone And Combination Of Steroids With Hyaluronidase On Mouth Opening In Oral Submucous Fibrosis Patients.

BACKGROUND: Eventually Oral submucous fibrosis causes pronounced stiffness and failure to open the mouth. Objectives are to determine compare the efficacy of intralesional steroids alone and combination of steroids with hyaluronidase on mouth opening in oral submucous fibrosis. METHODS: It was a prospective comparative cohort study. Total of 74 patients both male and female having history of pan chewing and limited mouth opening and burning sensations were included in the study. Informed consent was taken and divided into two groups. Patients of group 1 were managed with mixture of betamethasone 1 ml and hyaluronidase 1500 IU and patients of group 2 were treated with only steroid injection of betamethasone 1 ml given intralesional, both injections were given intralesional, by multiple puncture technique and once a week and continued for twelve weeks (3 months). And data compiled and analyzed in SPSS-20. RESULTS: The mean age of group 1 was 40.027±6.97 years, and mean age of Group 2 was 37.351±5.48 years. In both groups, the greatest number of cases aged from 31-59 years. Compared to females in both groups, the majority of patients were males. In 32 (86.4)% patients of group 1 showed efficacy compared with 18[43.2] patients in group 2 [p-0.000]. Conclusion: In this study Intralesional steroids with hyaluronidase injections are more efficient for opening the mouth in patients with oral sub-mucus fibrosis.

The Association Between Environmental Perchlorate, Nitrate, and Thiocyanate Exposure and Oral Pain in NHANES.

Aim: To examine the human exposure to perchlorate, nitrate, and thiocyanate, and their associations with oral pain (OP) in the general population from the U.S. Methods: A total of 13,554 participants were enrolled in the National Health and Nutrition Examination Survey. The urinary perchlorate, nitrate, and thiocyanate were measured using ion chromatography coupled with an electrospray tandem mass spectrometry. The multivariable linear and logistic regressions were performed to explore the associations of the urinary perchlorate, nitrate, and thiocyanate, with the prevalence of oral pain. Restricted cubic splines were used to explore the non-linearity. Results: There are 3,129 OP cases. There was a higher urinary level of perchlorate, nitrate, and thiocyanate in OP. We found that urinary thiocyanate was positively associated with OP (odds ratio [OR] = 1.06; [1, 1.13]; p = 0.049). Restricted cubic spines revealed that urinary thiocyanate was in a U-shape association with OP. Conclusions: Urinary thiocyanate was in a U-shape association with OP, suggesting that we should keep the exposure of thiocyanate under a reasonable range.

СHARACTERISTICS OF CYCLIN D1-MEDIATED REGULATION OF CELL CYCLE OF PERIPHERAL BLOOD LIMPHOCYTES OF CHORNOBYL CLEAN-UP WORKERS AND PERSONS WITH MALIGNANT NEOPLASMS OF THE ORAL CAVITY, OROPHARYNX AND LARYNGOPHARYNX. / KhARAKTERYSTYKA TsYKLIN D1-OPOSEREDKOVANOÏ REGULIaTsIÏ KLITYNNOGO TsYKLU LIMFOTsYTIV PERYFERYChNOÏ KROVI UChASNYKIV LIKVIDATsIÏ NASLIDKIV AVARIÏ NA ChAES TA OSIB, KhVORYKh NA ZLOIaKISNI NOVOUTVORENNIa POROZhNYNY ROTA, ROTOVOÏ TA GORTANNOÏ ChASTYN GLOTKY.

OBJECTIVE: to explore proliferative potential of peripheral blood lymphocytes of Chornobyl clean-up workers and persons with malignant neoplasms of the oral cavity, oropharynx and laryngopharynx by level of expression of cyclin D1 and quantitative parameters of cell cycle. MATERIALS AND METHODS: A total of 294 men aged (58.47 ± 7.32) were surveyed, 215 of them were Chornobyl clean"up workers (1986-1987), exposed at the dose range 10.43-3623.31 mSv; 49 persons of the control group and 30persons with malignant neoplasms of the oral cavity, oropharynx and laryngopharynx at III, IVА and IVВ stages ofthe disease. The analysis of parameters of cell cycle and proliferative activity of peripheral blood (PB) lymphocyteswas performed using the flow cytometry. The evaluation of distribution of cells by G0/G1, S, G2/M cell cycle phaseswas done in vivo and in in vitro. Proliferative potential was analyzed by level of expression of cytoplasmic protein ofcyclin D1. RESULTS: Proliferative potential of PB lymphocytes of Chornobyl clean"up workers and persons with malignant neo"plasms of the oral cavity, oropharynx and laryngopharynx was assessed. An increase in the level of spontaneousсyclin D1 expression and disturbance of сyclin D1-dependent regulation of cell cycle of PB lymphocytes after mito"gen activation were determined in the Chornobyl clean-up workers. An increase in pool of cells in the S" and G2/M"phases of cell cycle was detected, which characterizes high proliferative potential of PB lymphocytes. These changesare most pronounced in the subgroup of persons with a radiation dose of D > 500 mSv, and in persons with oncolo"gical pathology. CONCLUSIONS: A positive linear dependence has been established between the radiation dose and the number of cellsin the S"phase of cell cycle in the subgroup of Chornobyl clean"up workers with a radiation dose of D > 500 mSv. The detected changes of cyclin D1-dependent regulation of cell cycle and proliferative status of lymphocytes depend on the radiation dose, can be a manifestation of genome instability and be a cause for risks of oncogenesis, in a remote period after radiation exposure.

Postoperative oral dysfunction following oral cancer resection and reconstruction: A preliminary cross-sectional study.

OBJECTIVES: Oral cancer treatment reportedly causes decreased oral function, but few studies have examined the effects of oral cancer treatment on oral function in depth. This study aimed to comprehensively evaluate the oral function after treatment and classify the conditions related to oral dysfunction in patients with oral cancer. MATERIALS AND METHODS: We recruited participants, collected their background data, and evaluated their oral function from September 2019 to March 2021. Principal component analysis was used to identify the components of oral function measurement and oral health perception. Receiver operating characteristic analysis was performed to investigate the accuracy of oral function measurements in predicting oral intake and nutritional status. RESULTS: Fifty patients treated for oral cancer, including 33 (66.0%) males and 17 (34.0%) females, were included. Their median age was 71.0 years (interquartile range: 63.0-76.0). There were significant differences in oral dryness between males and females, occlusal force among different age groups, tongue pressure based on the tumor stage and performance of reconstructive procedures, and masticatory function and Eating Assessment Tool scores based on whether radiotherapy was performed (P < 0.05). The principal component analysis proposed that oral function measurements and subjective oral health perception could be divided into three main components (transport, oral hygiene, and occlusion type), which explain 61.5% of the variance of the phenomenon. CONCLUSION: A significant decrease in oral function after oral cancer treatment should be diagnosed as postoperative oral dysfunction. Postoperative oral dysfunction can be classified into three types, each of which may present with different pathologies.

Effects of Oral pH Changes on Smoking Desire.

BACKGROUND: Nicotine addiction is associated with nicotine absorption from the buccal mucosa, and it is stated that the main factor that determines nicotine absorption is saliva pH. In the literature, the effects of changes in saliva pH values after eating and drinking on smoking desire in smokers were not questioned. AIM: To show the effect of saliva pH changes on smoking desire. The secondary aim was to show the impact of coffee and water drinking on saliva pH and smoking on oral-dental health (oral hygiene and gingival bleeding). STUDY DESIGN: Case-control study. METHODS: A questionnaire was administered that included "Sociodemographic Data Form" and smoking history and Fagerström Test for Nicotine Dependence (FTND). Oral and dental examinations were performed with mirror sonds and using oral hygiene standard Silness and Leöe plaque index and DMFT Index (Index of Decayed Missing or Filled Teeth). Untreated saliva samples were taken, and baseline saliva flow rate and pH values were measured. To assess pH changes, saliva pH was remeasured after sugar-free instant coffee and water consumption. Smoking desire was evaluated with the Visual Analog Scale (VAS). RESULTS: In this study, 24 (55.8%) females and 19 (44.2%) males were among the 43 smoking and 39 nonsmoking cases. Smoking was significantly associated with poor oral hygiene (in smokers 4.71 (±1.40), in non-smokers 2.30 (±1.59); P < .01). DMFT index was higher in smokers than in non-smokers (in smokers 6.45 (±3.69), in non-smokers 3.87 (±2.67); P < .01). Gingival bleeding was more prevalent in smokers (0.68 (±0.76)) than non-smokers (1.20 (±0.90); P = .009). Salivary flow rates were lower in smokers (in smokers 2.56 (±1.34), in non-smokers 3.00 (±1.22), P = .06). In both groups, pH values increased after coffee consumption and decreased after water; in smokers basal: 6.67 (±0.41), pH coffee: 6.93 (±0.36), pH water: 6.85 (±0.33); in non-smokers pH basal: 6.84 (±0.37), pH coffee: 7.02 (±0.37), pH water: 6.97 (±0.31), P < .01. The VAS values of smokers at basal 4.73 (±3.21); P < 0.01, after coffee consumption 4.91 (±3.08); P < .01, and after water 3.15 (±2.72); P < .01. CONCLUSION: The saliva pH increased after coffee consumption and decreased after drinking water. Besides, VAS values decreased significantly after drinking water. The results suggest that a simple behavior such as drinking water may be used in conjunction with behavioral and cognitive therapies to pursue smoking cessation.

Biostimulatory Effects of Low-Intensity Pulsed Ultrasound on Rate of Orthodontic Tooth Movement and Associated Pain, Applied at 3-Week Intervals: A Split-Mouth Study.

Objective: Low-intensity pulsed ultrasound (LIPUS) is a noninvasive modality to stimulate bone remodeling (BR) and the healing of hard and soft tissues. This research evaluates the biostimulatory effect of LIPUS on the rate of orthodontic tooth movement (OTM) and associated pain, when applied at 3-week intervals. Methods: Twenty-two patients (11 males and 11 females; mean age 19.18 ± 2.00 years) having Angle's Class II division 1 malocclusion needing bilateral extractions of maxillary first bicuspids were recruited for this split-mouth randomized clinical trial. After the initial stage of alignment and leveling with contemporary edgewise MBT (McLaughlin-Bennett-Trevisi) prescription brackets (Ortho Organizers, Carlsbad, Calif) of 22 mil, followed by extractions of premolars bilaterally, 6 mm nickel-titanium spring was used to retract the canines separately by applying 150 g force on 0.019 × 0.025-in stainless steel working archwires. LIPUS (1.1 MHz frequency and 30 mW/cm2 intensity output) was applied for 20 minutes extraorally and reapplied after 3 weeks for 2 more successive visits over the root of maxillary canine on the experimental side whereas the other side was placebo. A numerical rating scale- (NRS-) based questionnaire was given to the patients on each visit to record their weekly pain experience. Impressions were also made at each visit before the application of LIPUS (T1, T2, and T3). Models were scanned with a CAD/CAM scanner (Planmeca, Helsinki, Finland). Mann-Whitney U test was applied for comparison of canine movement and pain intensity between both the groups. Results: No significant difference in the rate of canine movement was found among the experimental (0.90 mm ± 0.33 mm) and placebo groups (0.81 mm ± 0.32 mm). There was no difference in pain reduction between experimental and placebo groups (p > 0.05). Conclusion: Single-dose application of LIPUS at 3-week intervals is ineffective in stimulating the OTM and reducing associated treatment pain.

Evaluation of changes in oral health-related quality of life over time in patients with Sjögren's syndrome.

OBJECTIVES: To assess oral health-related quality of life (OHRQoL) and changes in OHRQoL in 3 years of patients with Sjögren's symdrome (SS). METHODS: Thirty-five SS patients and 23 non-SS individuals were enrolled. OHRQoL were quantitatively evaluated using the shortened Oral Health Impact Profile (OHIP-14). After 3 years, 22 patients and 14 controls tool the OHIP-14 survey again. RESULTS: The SS group had a significantly higher OHIP-14 score, which indicated a lower OHRQoL, than the non-SS group. Among individual questions in the OHIP-14, scores for 'trouble pronouncing words', 'uncomfortable to eat foods', 'self-conscious', and 'diet unsatisfactory' were markedly higher in the SS group than in the non-SS group. The OHIP-14 score significantly increased in 3 years in the SS group. Furthermore, there was an inverse correlation between the change rate of salivary flow rate and change of OHIP-14 scores in 3 years in patients with SS whose OHIP-14 score increased. Scores for 'irritable with other people', 'difficulty doing usual jobs', 'felt life less satisfying', and 'unable to function' significantly increased in 3 years. CONCLUSION: In SS, OHRQoL decreased in 3 years, which was associated with a decrease in saliva secretion. Moreover, troubles related to psychosocial aspects in SS patients were found to intensify over time.

An analysis of the completeness of referral forms and cases evaluated by an oral medicine specialized service

Introduction: Oral lesions are present in approximately 30% of the population worldwide. Although the mouth is an anatomical region that can be easily accessed for direct visual examination, most dentists of dental surgeons have reported difficulties in the diagnosis and management of oral diseases. The primary aim of this study was to assess the completeness of referral forms of the patients referred by dentists from the primary care basic health units to an Oral Medicine service. The secondary aim was to analyze if the complexity of the cases justify the referral to a specialist. Methods: Data from 131 referral forms of patients referred from June 2014 to April 2016 were retrieved from the records. The referral's completeness analysis comprised two stages. Stage 1 mainly comprised patient and applicant's information. In the Stage 2, the documents were scored according to amount of information, including the description of the lesion characteristics and the procedures required for the patients' diagnosis and management. The referral was considered justifiable if some procedures not available at primary care were required for diagnosis or treatment. Results: Five (9.8%) referral forms were considered well filled. Diagnosis agreement was 71.4%. Regarding the need of referral, 40,6% of the cases (n = 50) could be settle at the primary care. Conclusion: In conclusion, few referral forms had high-quality information and the many cases could be managed at primary care health services. (AU)

Recognizing and refuting the myth of tongue swallowing during a seizure.

OBJECTIVE: There is a harmful myth that persists in modern culture that one should place objects into a seizing person's mouth to prevent "swallowing the tongue." Despite expert guidelines against this, the idea remains alive in popular media and public belief. We aimed to investigate the myth's origins and discredit it. METHODS: A medical and popular literature review was conducted for the allusions to "swallowing one's tongue" and practice recommendations for and against placing objects into a seizing person's mouth. Current prevalence of these beliefs and relevant anatomy and physiology were summarised. RESULTS: The first English language allusions to placing objects in a patient's mouth occurred in the mid-19th century, and the first allusions to swallowing one's tongue during a seizure occurred in the late 19th century. By the mid-20th century, it was clear that some were recommending against the practice of placing objects in a patient's mouth to prevent harm. Relatively recent popular literature and film continue to portray incorrect seizure first aid through at least 2013. There is ample modern literature confirming the anatomical impossibility of swallowing one's tongue and confirming the potential harm of putting objects in a patient's mouth. CONCLUSION: One cannot swallow their tongue during a seizure. Foreign objects should not be placed into a seizing person's mouth. We must continue to disseminate these ideas to our patients and colleagues. As neurologists, we have an obligation to champion safe practices for our patients, especially when popular media and culture continue to propagate dangerous ones.

Oro-facial fibrosis in systemic sclerosis: a reconstructive journey.

Oro-facial fibrosis presents a significant disease burden in patients with systemic sclerosis, but there remains no established treatment modality. Autologous fat grafting is a minimally invasive surgical procedure that is now increasingly recognised for its regenerative capacity, propagating an expansion of heterogeneous indications beyond volume restoration, including fibrotic diseases such as systemic sclerosis. We present a 42-year-old woman with oro-facial involvement of systemic sclerosis leading to severe limitation in mouth opening and closure, with marked retraction of the lower lip and gingival display. We describe the reconstructive journey over a 12-year period, where the antifibrotic effect of autologous fat grafting served as the basis on which a series of surgical procedures were performed to achieve functional and aesthetic improvement. Autologous fat grafting provides a novel treatment modality for oro-facial skin fibrosis, previously considered a non-treatable disease manifestation of systemic sclerosis.

A Case of Long-standing Temporomandibular Joint Dislocation: Restoration of Oral Function Following Condylectomy.

BACKGROUND: Temporomandibular joint (TMJ) dislocation can be categorized into three groups: acute, habitual or recurrent, and long-standing. Long-standing TMJ dislocation refers to a condition that persists for more than one month without reduction. Long-standing dislocation of the TMJ is rare and the most challenging and difficult to treat of the three. CASE REPORT: The present case study relates to a 53-year-old woman with long-standing TMJ dislocation of a year's duration who presented for treatment. Due to this condition, she was unable to take food orally, and nutrition was managed by gastrostomy tube feeding. She also suffered from schizophrenia and had been admitted to a closed hospital. Bilateral mandibular condylectomy was performed, restoring oral function. However, post-reduction, an open bite remained, restricting the types of food that she could eat. Additional intermaxillary fixation and intermaxillary traction would have been required for an optimal outcome, but they were not possible for this patient. CONCLUSION: Despite an inability to provide comprehensive treatment, due to patient-related factors, occlusal and masticatory functions were restored to adequate levels following bilateral condylectomy alone. This enabled oral feeding and improved her quality of life.

Common causes of 'swelling' in the oral cavity.

BACKGROUND: Conditions that present as a 'swelling' in the oral cavity are relatively common, and patients may seek initial assessment from their general practitioners. OBJECTIVE: The aim of this article is to provide an overview of common causes of a 'swelling' in the oral cavity to help with formulating a differential diagnosis and stratifying the urgency of referral. DISCUSSION: Pathological conditions in the oral cavity (excluding mucosal presentations) may present as a swelling in the submucosa or jaws, symptoms related to teeth and/or gums or an incidental finding on imaging. In this review, the authors outline the most common submucosal or jaw swellings, organised according to their clinical presentations, and describe their typical appearance and management.

Reproducibility of measurements on physical performance in head and neck cancer survivors; measurements on maximum mouth opening, shoulder and neck function, upper and lower body strength, level of physical mobility, and walking ability.

BACKGROUND: Survivors of Head and Neck Cancer experience specific problems in functional performance. The aim of this study was to obtain the test-retest reliability of measurements on Maximal Mouth Opening (MMO), shoulder and neck function, lower and upper body strength, level of mobility and walking ability. MATERIALS AND METHODS: Test-retest study design. Measurements on MMO (intra- and extra orally), Active range of motion of shoulders and neck, 30 Seconds Chair Stand Test, Grip Strength, Timed Up and Go test, and Six Minute Walk test. RESULTS: In total 50 participants were included. The mean age was 68.6. ± 9.9 years and median time since end of treatment was 3.0 years (Q1-Q3: 1.0-5.25 years). We found good to excellent test-retest reliability on the core set of measurements (Intraclass Correlation Coefficient (ICC) 0.77 to 0.98). Measurement of MMO with cardboard card, forward flexion shoulder and Six Minute Walk test had a relatively small measurement error (Smallest Detectable Change (SDC) % 5.4% - 15.1%). Measurement of MMO with a caliper, shoulder abduction, shoulder external rotation, later flexion and rotation of the neck, grip strength, 30 Seconds Chair Stand Test, and Timed up and Go test had a relatively large measurement error (SDC% 19.8% - 44.7%). CONCLUSION: This core set of measurements on physical performance is found reliable and therefore able to differentiate in physical performance. The reported measurement errors should be taken into consideration when interpreting the results of repeated measurements. IMPLICATIONS FOR CANCER SURVIVORS: A core set of physical measurements can be used to measure physical performance in survivors of Head and Neck Cancer.

Association among kidney function, frailty, and oral function in patients with chronic kidney disease: a cross-sectional study.

BACKGROUND: Chronic kidney disease (CKD) involves many factors that can cause frailty and oral hypofunction. We aimed to investigate the prevalence of frailty and oral hypofunction and to examine the associations among kidney function, frailty, and oral function in adults with CKD in Japan. METHODS: This cross-sectional study was conducted at two institutions. The participants included 109 patients with CKD stages 3-5 who visited outpatient clinics or were admitted for inpatient treatment. Frailty was evaluated using the Japanese version of the Cardiovascular Health Study frailty criteria. Oral function was evaluated by assessing oral motor skills [oral diadochokinesis (ODK) rate], masticatory ability, and the repetitive saliva swallowing test. The estimated glomerular filtration rate (eGFR) was used to indicate kidney function. We examined the associations among kidney function, frailty, and oral function using binomial logistic regression analysis. RESULTS: In total, 31 participants (28.4%) were classified as being frail. Univariate analysis showed that age, body mass index, eGFR, and haemoglobin level were significantly associated with frailty. ODK and swallowing function were significantly associated with frailty. Multivariate analysis revealed that frailty was significantly associated with eGFR [odds ratio (OR) 0.96, 95% confidence interval (CI) 0.92-1.00, p = 0.048] and ODK rate (OR 0.68, CI 0.47-0.98, p = 0.038). However, no significant association was found between CKD severity and masticatory or swallowing function. CONCLUSION: We found a high prevalence of frailty in patients with CKD and a significant association between frailty and oral motor skills, affecting the swallowing function of patients with nondialysis CKD. The high prevalence of frailty among patients with CKD suggests that routine assessment of frailty is necessary to prevent the development of severe complications. In addition, oral and kidney function should be carefully evaluated, and oral health education and interventions should be performed for patients with CKD.
