Parafunctional habits, such as bruxism, are contributory factors for temporomandibular disorders (TMD). The aim of this study was to evaluate the maximal bite force (MBF) in the presence of TMD and bruxism (TMDB) in young adults. Twelve women (mean age 21.5 years) and 7 men (mean age 22.4 years), composed the TMDB group. Ten healthy women and 9 men (mean age 21.4 and 22.4 years, respectively) formed the control group. TMD symptoms were evaluated by a structured questionnaire and clinical signs/symptoms were evaluated during clinical examination. A visual analogical scale (VAS) was applied for stress assessment. MBF was measured with a gnatodynamometer. The subjects were asked to bite 2 times with maximal effort, during 5 seconds, with a rest interval of about one minute. The highest values were considered. The data were analyzed with Shapiro-Wilks W-test, descriptive statistics, paired or unpaired t tests or Mann-Whitney tests when indicated, and Fisher's exact test (p < 0.05). TMDB women presented lower values of MBF as compared to those presented by TMDB men and by the control group. MBF for TMDB men was similar to that of the control group. The proportion of TMDB women with muscle pain and facial/teeth/head pain upon waking up was significantly higher than that of men. Control women presented significantly lower stress scores than the others. It was concluded that MBF was reduced in TMDB women, as they presented more signs and symptoms. Men presented higher MBF values than women, but TMD and bruxism did not significantly decrease MBF. Stress was not an influencing factor for TMD and bruxism in men.

PURPOSE: The purpose of this study was to evaluate the presence of signs and symptoms of temporomandibular disorders (TMD) in children with headaches in a neuropediatric ambulatory. METHOD: Fifty patients between 4 and 18 years of age were examined: 31 had headaches (24 migraine, 4 tension type and 3 unspecific headache) and 19 formed the control group. The data collection was comprised of a structured questionnaire answered by the children's parents, and a subjective evaluation about the children’s emotional state. A specific questionnaire for TMD was applied, followed by a clinical dental examination of the children. As signs of TMD, mouth opening limitation, mandibular trajectory deviation in opening mouth, and joint noise were considered. As symptoms, pain on palpation of masseter and temporal muscles and on the poromandibular joint. RESULTS: A significant increase in signs and symptoms of TMD was found in patients with headaches when compared to the control group. There was also a significant difference in signs and symptoms of TMD according to age (increased with age) and emotional state (tense> calm). CONCLUSION: There is a higher frequency of TMD in pediatric patients with headaches; thus, it is important to look for TMD signs and symptoms in this population.

ABSTRACTObjectives: The objectives of this study were to assess the prevalence of temporomandibular disorders (TMDs) in patients with relapsing-remitting multiple sclerosis (MS) and to investigate whether an association exists between the presence of TMD symptoms and the degree of MS-related disability. Materials and Methods: In all, 120 individuals were evaluated: 60 patients with a diagnosis of relapsing-remitting MS and 60 age- and sex-matched controls without neurological impairments. A questionnaire recommended by the European Academy of Craniomandibular Disorders for the assessment of TMD symptoms was administered. For those who answered affirmatively to at least one of the questions, the RDC/TMD Axis I instrument was used for a possible classification of TMD subtypes. The Expanded Disability Status Scale (EDSS) was the measure of the degree of MS-related disability. Statistical Analysis Used: Fisher’s exact test was used to analyze the data. ANOVA was used to detect significant differences between means and to assess whether the factors influenced any of the dependent variables by comparing means from the different groups. Results: The prevalence of TMD symptoms in patients with MS was 61.7% versus 18.3% in the control group (CG). A diagnosis of TMD was established for 36.7% in the MS group and 3.3% in the CG (P = 0.0001). There were statistically significant differences between degrees of MS-related disability and the prevalence of TMD (P = 0.0288). Conclusions: The prevalence of both TMD and TMD symptoms was significantly greater in the MS group. EDSS scores and TMD prevalence rates were inversely related.

Abstract Background Multiple sclerosis (MS) is an autoimmune disease of the central nervous system, characterized as an inflammatory demyelinating disease. It presents a diversity of neurologic signs and symptoms as well the incapacities. Since the need for advances in MS treatment, many studies are for new therapeutic technologies, mainly through using preclinical models as experimental autoimmune encephalomyelitis (EAE). This study aimed to observe and analyze the development in Lewis rats-induced model of EAE. Methods It was used 23 females of Rattus norvegicus, from 6 to 8 weeks, weighing around 170 g. Of 23 rats, 19 underwent EAE induction distributed in six groups to establish the evolution of clinical signs. B. pertussis toxin (PTX) doses were 200, 250, 300, 350–400 ng, and four animals as the control group. The animals had weight and scores analyzed daily, starting seven and ending 24 days after induction. Then, all animals were euthanized, and the brain and spinal cord were collected for histopathological analyses. Results The results showed that the dose of 250 ng of PTX induced de higher score and weight reduction. All groups who received the PTX demonstrated histopathological findings. Those characterized as leukocyte infiltration, activation of microglia and astrocytes, and demyelinated plaques in the brain. In the spinal cord, the loosening of the myelinated fibers was observed by increasing the axonal space in all tested doses of PTX. Conclusions EAE was not dose-dependent. Histopathological findings do not proportionally related to clinical signs, as in human patients with MS.

Context: Heavy metals, including thallium and lead, are introduced to illicit drug users’ body as a result of using drugs such as cocaine and heroin. Objective: This study aimed to determine urine, blood, and hair thallium (Tl) concentrations in illicit opioid users along with the relevant clinical signs and symptoms consistent with thallotoxicosis and to compare them with the corresponding variables in the control non-opioid user group. Materials and Methods: This case–control study was conducted on 50 illicit opioid users who had abused opioids continuously for more than a year, referred to Amirie Drug Abuse Treatment Clinic in Kashan, Iran. The control group included 50 non-opioid users. Thallium concentrations in urine, blood, and hair were assessed in both groups ( n = 100) using electrothermal (graphite furnace) atomic absorption spectrometry (ET AAS, GF AAS). Results: In the studied group, the median (interquartile range) concentrations of thallium in urine, blood, and hair were 54.8 ± 79.9 μg/L, 14.5 ± 11.1 μg/L, and 5.4 ± 3.7 µg/g, respectively; these values were 4.8 ± 5.2 μg/L, 2.5 ± 2.4 μg/L, and 1.4 ± 1.1 µg/g, respectively, in the control group. There were significant differences in urine, blood, and hair thallium concentrations between the study group and the control group ( p < 0.001). There were significant correlations between duration of illicit opioid use and urine thallium concentrations ( r = 0.394, p = 0.005) and hair thallium concentrations ( r = 0.293, p = 0.039), but not with blood thallium concentrations ( r = 0.246, p = 0.085). Urine and blood thallium concentrations of illicit opioid users with clinical signs and symptoms consistent with thallotoxicosis of weakness ( p = 0.01), depression ( p = 0.03), and headache ( p = 0.03) were higher than users without these problems. Discussion and conclusion: The results of the study showed that thallium concentrations in urine, blood, and hair in illicit opioid users were significantly higher than the comparable concentrations in the control group. This can be due to the use of illicit opioids adulterated with thallium. Also, this study showed long-term illicit opioid use may lead to thallium exposure. In addition, cigarette smoking was associated with increased thallium exposure.

Background: Previous studies do not agree with each other on the association between electrodiagnostic findings and clinical symptoms of Carpal tunnel syndrome (CTS). In most of these studies, many variables such as age, sex, obesity and hypothyroidism have not been taken into account. Material & methods: About 62 patients with hypothyroidism and 62 patients without hypothyroidism with sign and symptoms of CTS were included in this study. Electrodiagnostic tests were done for all patients. And relationship of the severity of CTS signs and symptoms with electrodiagnostic parameters was examined statistically in each group. Results: This study showed that distal motor latency in control group (without hypothyroidism) is significantly more prolonged than hypothyroid patients. Also there was significant correlation between clinical symptoms and electrodiagnostic findings in control group, but there was not such correlation in hypothyroid patients. In 62% of hypothyroid patients with clinical signs and symptoms of CTS, electrodiagnostic findings were normal and only in 38% of cases, electrodiagnostic findings were suggestive of CTS. Conclusion: Relationship of the severity of CTS signs and symptoms with electrodiagnostic parameters is very weak in hypothyroid patients. Many hypothyroid patients with clinical signs and symptoms of CTS have normal electrodiagnostic findings; so we need more studies for revising the para-clinic criteria of labeling patients having CTS in hypothyroid patients.

Abstract Context: Bisphosphonate-related osteonecrosis (BON) of the jaws is a newly identified condition for which the exact mechanism involved in its pathogenesis remains obscure. Objective: The objective of the study was to evaluate whether diabetes mellitus (DM) may be a contributing factor in the development of BON. Design: From 2004 to 2006, 31 patients were diagnosed with BON. The diagnosis of BON was based on the medical and dental history of each patient as well as the observation of clinical signs and symptoms of this pathological process. DM was based on two consecutive fasting blood glucose levels above 7 mmol/liter. Setting: The study was completed in the Hebrew University-Hadassah Hospital referral center. Results: Of the 31 patients with BON, 18 (58%) were found to have DM or impaired fasting glucose. The proportion of diabetic patients was much higher than expected relative to the incidence of DM in the general population (14%) and compared with the proportion of diabetic patients in a control group of oncological patients treated with bisphosphonates and without BON (12%) (P = 0.00003). Conclusions: This finding indicates that DM may be a risk factor for BON and that DM patients treated with bisphosphonates should be carefully monitored. We discuss here the bone metabolic pathways characteristic of DM patients and the way in which these pathways can augment the effects of bisphosphonates.

To evaluate functional and periodontal aspects in patients with unilateral or bilateral congenitally missing maxillary lateral incisors, treated with either implants or space closure and tooth re-contouring. The sample consisted of 68 volunteers, divided into 3 groups: SCR - space closure and tooth re-contouring with composite resin (n = 26); SOI – implants placed in the area of agenesis (n = 20); and CG - control group (n = 22). A modified Helkimo questionnaire and the Research Diagnostic Criteria for Temporomandibular Disorders were used by a single, previously calibrated evaluator to assess signs and symptoms of temporomandibular joint disorder. The periodontal assessment involved the following aspects: plaque index, bleeding upon probing, pocket depth greater than 3 mm, gingival recession, abfraction, periodontal biotype and papilla index. The data were analyzed using Fisher's exact test and the nonparametric Mann-Whitney and Kruskal-Wallis tests (α=.05). No differences in periodontal status were found between treatments. None of the groups were associated with signs and symptoms of temporomandibular joint disorder. Both treatment alternatives for patients with congenitally missing maxillary lateral incisors were satisfactory and achieved functional and periodontal results similar to those of the control group.

Aim:  The aim of this study was to compare the efficacy of Alveogyl, 0.8% hyaluronic acid (HA), and 0.2% chlorhexidine digluconate (CHX) gel in reducing pain and improving clinical signs and symptoms of alveolar osteitis. Methodology: The clinical data of patients treated for alveolar osteitis between 01/01/2015 and 01/01/2019 were retrieved for this study. All patients were initially treated by curettage and physiological saline irrigation. Patients were then divided into 4 groups. Group 1 was considered the control group; no other biomaterials were administered after curettage and physiological saline irrigation. All other groups were administered an additional treatment in the socket after curettage and physiological saline irrigation (Group 1 – Alveogyl; Group 2 - 0.8% HA; Group 3 - 0.2% CHX). Patents were evaluated before surgery as well as days 3 and 7 after surgery. The postoperative evaluations included: Visual analog scale(VAS) pain scores, the presence of clinical signs and symptoms of exposed alveolar bone, disorganized blood clot, inflammation around the socket, and bad odor and taste. Results: Sixty-seven patients were included in the study. There was no statistically significant difference between groups in all control evaluations (p>0.05). There was significantly reduced inflammation around the extraction socket on postoperative day 7 in the CHX group compared to that in the control group (p<0.05). No other significant changes in clinical signs and symptoms were observed among groups. Conclusion: There was no significant difference between curettage with physiological saline irrigation alone and the addition of Alveogyl, 0.8% HA, or 0.2% CHX in the reduction of pain in alveolar osteitis. Nonetheless, CHX may reduce inflammation around the extraction sockets.   How to cite this article: Dereci Ö, Görkem T, Koşar YÇ.
