Temporomandibular dysfunction and tinnitus the knowledge of the dental surgeon in primary health care.

A longitudinal study of quantitative nature applied through a structured and self-administered questionnaire. The purpose of the questionnaire was to verify the knowledge of the Primary Health Care Dentist (PHC) on the interrelationship between temporomandibular dysfunction and tinnitus after continuing education. The collected data (n=37) indicated insufficient knowledge with no significant statistical difference in knowledge or professional conduct. It is important to emphasize the importance of instructing and strengthening the knowledge of the PHC professional on the interrelationship between temporomandibular dysfunction and tinnitus. This may help minimize problems such as the professionals' lack of attention in the routine of care in changes that affect the patients' quality of life. Moreover, there is a need to sensitize managers to institute tools that subsidize the professional in this care with resoluteness.

Relationship between Otological Symptoms and TMD.

BACKGROUND: Patients with any type of temporomandibular disorder (TMD) may have several symptoms in their temporomandibular joints, masticatory muscles and associated structures, and may have otological symptoms such as tinnitus, ear fullness, ear pain, hearing loss, hyperacusis, and vertigo, which may be due to the anatomical proximity between the temporomandibular joint, muscles innervated by the trigeminal nerve, and ear structures. Objective: This study found a prevalence of ear complaints described in the medical records of patients (n = 485) at the Center for Diagnosis and Treatment of the Temporomandibular Joint and Dental-Facial Functional Alterations at Tuiuti University of Paraná (CDATM/UTP), with TMD evaluated by the Research Diagnostic Criteria/Temporomandibular Disorders (RDC/ TMD). METHOD: After approval by the ethics committee were examined 485 medical records of patients of the CDATM/UTP, of both sexes a period of 2 years. The data analyzed were gender, age and the presence of reported otologic symptoms. The data were organized and subjected to statistical analysis using SPSS (IBM Statistic 20.0). RESULTS: The results showed a higher number of female patients between 41 and 50 years old. There was a prevalence of otological symptoms (tinnitus, deafness, dizziness, imbalance, and ear fullness) in 87% of TMD cases, regardless of sex and age. Tinnitus was the symptom with the highest prevalence (42%), followed by the ear fullness (39%). CONCLUSION: These data support the correlation between temporomandibular disorders and otological symptoms, even without being caused directly by the ear.

Tinnitus and temporomandibular disorders: the knowledge of professionals for primary health care in the city of Curitiba.

INTRODUCTION: The high prevalence of temporomandibular disorders and tinnitus along with the negative effects on the quality of life of affected individuals makes this association a matter of public health. OBJECTIVE: To assess the knowledge of primary health care professionals about the interrelationship between temporomandibular disorders and tinnitus. MATERIALS AND METHODS: This was a quantitative cross-sectional study, using a structured, self-administered questionnaire for a group of 54 dental surgeons. The statistical analysis used involved descriptive analyses through absolute and relative frequency distributions. RESULTS: The results showed that the professionals do not, as a routine, examine the temporomandibular joints and masticatory muscles during physical examination. In addition, there was a low percentage of correct answers on questions that assess knowledge. CONCLUSIONS: There is a need to inform dentists about the interrelationship between temporomandibular disorders and tinnitus. Furthermore, there is a need to encourage managers to establish teaching and learning tools that support and strengthen the role of dentists in primary health care. In this way, routine visits might minimize these disorders, and thus contribute to the quality of life of the population.

Analgesic effect of Hypericum perforatum, Valeriana officinalis and Piper methysticum for orofacial pain

To evaluate in vivo the association of hypericum Hypericum perforatum, valerian Valeriana officinalis and kava Piper methysticum with analgesia by assessing their effects in reducing orofacial pain as well as the possible hepatic, hematologic and biochemical alterations induced by regular administration of these extracts. METHODS: Orofacial pain was induced in mice with the administration of 2.5% formalin in the upper lip. After 60 min, the animals were treated with saline, carbamazepine and hydroalcoholic plant extracts. The nociceptive intensity was determined by the timing at which the animal remained rubbing the injected area. To assess the hepatotoxic effect, mice were chronically treated for 25 days with saline, carbamazepine and hydroalcoholic extract. The animals were euthanized and the liver weighed, followed by a differential count of leukocytes and measurement of alanine transaminase and alkaline phosphatase. RESULTS: The evaluation of analgesic activity in phase 1 reduced the time of rubbing compared to the control by 86% 0.05 mL/10 g and 76% 0.10 mL/10 g. In phase 2, the extracts reduced rubbing time by 94% and 85%, respectively. In the evaluation of alkaline phosphatase, the groups treated with extracts at doses of 0.05 mL/10 g and 0.1 mL/10 g increased by 16.1% and 9.5% compared to the control group and a reduction of 8.5% and 9.1% in the evaluation of alanine transaminase respectively. It was demonstrated that in the differential counts showed an increase in eosinophils in the treated group with 0.05 mL/10 g. CONCLUSIONS: The use of hydroalcoholic extract of the associated plants reduced the orofacial formalin-induced pain with better results than carbamazepine, at both the neural conductor level of pain phase 1 and in inflammatory or later pain phase 2 without presenting hepatotoxicity. The observed eosinophilia is suggestive of a phenomenon called hormesis...
