Rheumatoid Arthritis (RA) is an inflammatory autoimmune disease, affecting multiple joints. Temporomandibular joint disorders (TMD) are common in these patients. Also, parafunctional habits can lead to signs and symptoms of TMD. The purpose of this study was to determine the prevalence of TMD and parafunctional habits in patients with RA.

Forty patients with RA (according to ACR-1987 criteria) participated in this cross-sectional study. The patients’ information was collected by clinical examination and questionnaire. The DAS-28 criteria were employed to determine the disease severity. Thereafter, the TMD (according to RDC/TMD criteria) and parafunctional habits were compared to the control group (n=40).

85% of RA patients had at least one sign or symptom of TMD. The prevalence of joint sound and jaw deviation in patients with RA were 75 and 27.5%, respectively. These values were significantly higher than the values in the control group. A comparison between parafunctional habits demonstrated that both groups had the same frequency for bruxism and clenching. The masticatory muscle tenderness was reported in 32.5% of RA patients.

The prevalence of TMD in patients with RA is considerably higher than in healthy group. Unlike patient’s expressions, more tooth wear and muscle tenderness may indicate the probability of prevalence of bruxism and clenching in these patients.

Bruxism in children negatively affects the quality of life. The present study aimed to evaluate theprevalence of bruxism and its associated factors among 3-6-year-old children in Yazd in 2018. This cross-sectional (descriptive-analytical) study was conducted on 270 3-6-year-old children who were selected via cluster sampling in Yazd. The needed data were collected through parent questionnaire (demographic characteristics of child and parents, as well as child's medical history) and the children's assessment form (muscle examination, occlusion, temporomandibular joint (TMJ), and decayed, missing, and filled teeth (dmft)). The validity of the questionnaires was validated by experts' opinions, and the reliability of the questionnaires was confirmed rendering a Cronbach's alpha coefficient of 0.87. Data were analyzed in SPSS software. As evidenced by the obtained results, the prevalence of bruxism in 3-6-year-old children in Yazd was obtained at 46.7%. The relationship between bruxism in these children and gender was not significant, while the association between bruxism and age was significant (p < /em>=0.0001). There was no statistically significant relationship between parental education and bruxism in children; nonetheless, the relationship between parents' occupation and the prevalence of bruxism in children was significant. Children with bruxism have a family history of bruxism among their families. Furthermore, a statistically significant relationship was detected between bruxism and sleep talking, restless sleep, child dysthymia, prognosis, complaints of temporal pain, complaints of dental pain without signs of decay, type of occlusion, and limitation in mouth opening of children. Based on the results of the current study and the effect of such factors as parental occupation, sleep disorders, and dysthymia on the development of bruxism in children, it is necessary to increase parental knowledge through educational programs in an attempt to prevent and reduce the prevalence of bruxism in community.

Temporomandibular joint dysfunction (TMD) is very common and this high prevalence makes its diagnosis and therapeutic methods necessary. In many cases, in addition to the position of the disc, the morphology of other joint components such as joint protrusion can also be deformed, suggesting a possible association between the position of the disc and the morphology of the bony components of the joint. Headache is among the most common complaints in patients suffering from temporomandibular joint disorder. Thus, it seems that evaluation of patients with headache in terms of TMD is necessary. In patients with TMD parafunctional activities play an important etiologic role considering the high prevalence of bruxism and TMD in patients with headache. So, there is important relationship between headache and TMD. Some factors can affect TMD, such as trauma, dental premature contacts, parafunctional habits and psychological factors. Cochrane, Embase, Google scholar, and BMJ clinical evidence were searched directly by using relevant key words during last six years because of the high number of studies in this field, we discuss about bruxism and TMD, TMD and headache, and bruxism and headache treatment. Bruxism and Temporomandibular disorder are the two main problems that is common treatment of these two phenomen would be effective in the treatment of headache.

Definitive diagnosis of restoring worn surfaces and simultaneous control of the causes of these wears is considered a viable therapeutic option. In this paper, we have described the surgical therapeutic sequence of esthetic crown lengthening and restoration in a patient with bruxism and moderately worn dentition.
Case Report: An 18-year-old male patient referred to the Periodontology Department of the School of Dentistry at Tehran University of Medical Sciences, Iran. The treatment plan involved a crown lengthening surgery in the maxillary anterior sextant and an internal bleaching procedure for the maxillary left central incisor of the patient, followed by the reconstruction of the anterior maxillary sextant with ceramic veneer (IPS e.max). Two months after the recovery of the crown lengthening surgery, crown reconstruction was accomplished. In addition to preventing biologic violation, the crown of the lost tooth and the vertical dimensions of the teeth were also restored

Headache is among the most common complaints in patients suffering from temporomandibular joint disorders (TMD). Thus, it seems that evaluation of patients with headache in terms of temporomandibular joint (TMJ) disorders is necessary. In people with TMD, parafunctional activities play an important etiologic role. Considering the high prevalence of bruxism and TMDs in patients with headache, assessment the accuracy and severity of this association can play a key role in diagnosis and treatment of these two phenomena. The purpose of this study was to investigate the relationship between bruxism, TMD and headache, also assessment the efficacy of TMD conservative therapy with a special approach to self-management in treating patients with headache.
Motor searches of Cochrane, Medline and EMbase databases, PubMed, Google Scholar, Uptodate, BMJ clinical Evidence, MD consult and science direct by using of relevant key words were searched for article published between 2000 and 2015. A total of English language abstracts were reviewed, 80 full articles were obtained and among them, 30 relevant articles were reviewed in this study. Because of the high number of studies in this field, we divided the data into four group, bruxism and TMD, TMD and headache, bruxism, TMD and headache, treatment.
Bruxism and temporomandibular disorders are the two main contributing factors in initiation and perpetuation of headache. Treatment of these two phenomena would be effective in the treatment of headache.

Bruxism is a growing concern in children that has led to negative impact on quality of life. The aim of this study was to determine the quality of life in children 8-9 years old with bruxism in Hamadan city, 2012. In this case- control study 130 students 8-9 year old using a probe, mirror and natural light were examined as well as the questioning of the child (showing how to bruxism), acquaintances, teachers and classmates, 65 students who had bruxism chosen. The questionnaire was given to parents of bruxism and control groups. Data obtained from the questionnaire was analysis with the statistical software SPSS v.16.0 and t-test. In the present study, the bruxism with students age, father's occupation, father's education, mother's education, place of residence, socioeconomic status, living with two parents, divorced (separated) parents, family size, family history bruxism, history and other oral habits, argument in the family, children's education, father's chronic disease, mother's chronic disease and father's addiction was significantly associated (P<0.05), but bruxism with the sex, the family birth rate and mothers addiction was not significantly associated (P>0.05). Quality of life of students with bruxism was significantly lower than quality of life of healthy children. (not having bruxism) (P<0.05). Oral parafunctional habits impact on tooth and jaw, if diagnosed lately and delayed treatment would be led to serious problems, early diagnosis for prevention of disease and education of parents and children to reduce the incidence and complications of bruxism is necessary.

Temporomandibular Disorder (TMD) was generally Presumed to be a condition affecting only adults. However, epidemiological studies have reported incidences of TMD to be just as high in children. The purpose of this study was to assess the prevalence of signs and symptoms of TMD in children aged 7-9 years in schools of Tehran in 2010. In this descriptive study 400 subjects (Male195- Female205), 7-9 years of age in schools of Tehran were (sampling multi stage) randomly selected. The questionaire was completed by all the individuals and clinical examination was carried out with Research Diagnostic criteria. Prevalence of TMD in samples were determined and the relationship between relevant factors like bruxism, posterior crossbite, anterior open bite, deep bite, Trauma gender and occlusal problem was evaluated by chi Square analysis. our study indicated that at least one sign and symptom was present in 65.2% of Children. Bruxism, Class III, deep bite were significantly related with TMD (P<0.05). There is a high prevalence of TMD in pediatric patient due to: lack of parental attention, misdiagnosis by medical professional, and inability of pediatric patients to properly explain and identify their symptoms.
