Cervical signs and symptoms in patients with Meniere's disease: a controlled study.

This study compares the frequency of signs and symptoms from the cervical spine in 24 patients diagnosed with Meniere's disease and 24 control subjects from a population sample. From a previous controlled comparative study concerning signs and symptoms of craniomandibular disorders, 24 patients diagnosed with Meniere's disease (10 males and 14 females) and their 24 matched control subjects participated in this investigation on the state of the cervical spine. Symptoms of cervical spine disorders, such as head and neck/shoulder pain, were all significantly more frequent in the patient group than in the control group. Most of the patients (75%) reported a strong association between head neck movements in the atlanto-occipital and atlanto-axial joints and triggered attacks of vertigo. Also, 29% of the patients could influence their tinnitus by mandibular movements. Signs of cervical spine disorders, such as limitations in side-bending and rotation movements, were significantly more frequent in the patient group than in the control group. Tenderness to palpation of the transverse processes of the atlas and the axis, the upper and middle trapezius, and the levator scapulae muscle were also significantly more frequent in the patient group. The study shows a much higher prevalence of signs and symptoms of cervical spine disorders in patients diagnosed with Meniere's disease compared with control subjects from the general population.

Craniomandibular disorders in patients with Menière's disease: a controlled study.

This study compares the frequency of signs and symptoms of craniomandibular disorders and dental conditions in patients diagnosed with Menière's disease and in control subjects from a population sample. Thirty-one patients (12 men, 19 women) diagnosed with Menière's disease were referred from three otolaryngologic clinics for clinical examination and possible treatment of craniomandibular disorders. Thirty-one control subjects were selected from the population in the same area of Sweden (Ystad). Both groups were subjected to a screening of their symptoms with a self-administered questionnaire and to a routine stomatognathic examination. The function of the masticatory system was further calculated according to the index of Helkimo for both anamnestic dysfunction (Ai) and clinical dysfunction state (Di). Clinical symptoms of craniomandibular disorders such as pain in the face or jaw; pain on movement of the mandible; fatigue of the jaws; and pain located in the vertex area, the neck/shoulder area, and the temples all occurred significantly more often in the patient group. Findings at the clinical examination included a statistically higher frequency of tenderness to palpation of the masticatory muscles, the temporomandibular joint, and the upper part of the trapezius muscle in the patient group compared to that of the control group. The findings indicate a much higher prevalence of signs and symptoms of craniomandibular disorders in patients diagnosed with Menière's disease than in the general population.

Etiology of craniomandibular disorders: evaluation of some occlusal and psychosocial factors in 19-year-olds.

This study involved 264 19-year-old adolescents who comprised 93% of an epidemiologic sample followed longitudinally from the age of 17. Case histories as well as self-ratings of anxiousness and comfort in daily living were collected with the aid of a questionnaire. The clinical examination included evaluation of TMJ, muscles, jaw mobility, and occlusion. The number of contacting teeth in the intercuspal position during light pressure was the occlusal factor with the most significant relationships to symptoms of mandibular dysfunction. Being tense was significantly related to a number of signs and symptoms of mandibular dysfunction. The risk ratio of having craniomandibular disorders was about three times as high in the group with few contacting teeth in the intercuspal area compared to those with the most occlusal contacts. The group who estimated themselves as tense had a risk ratio of craniomandibular disorders 3.4 to 8.5 times higher than those who did not experience tension. When the groups were constructed on the basis of combination of tension and few contacting teeth, these factors seemed to potentiate the risk ratios to values from 3.9 to 21 times those with most occlusal contacts and no experience of being tense.

Temporomandibular joint sounds in adolescents: a longitudinal study.

A 2-year longitudinal study on signs and symptoms of mandibular dysfunction was performed with 285 17-year-old adolescents living in a certain geographic area in Skellefteå, Sweden. Crepitation was neither reported nor recorded in any subject. Both reports and recordings of TMJ clicking sounds fluctuated with time. The 2-year period prevalence was 24%, and 5.8% consistently reported TMJ clicking sounds. The corresponding figures for clinically recorded clickings were 36% and 9.3%, respectively. Both reported and recorded joint sounds were significantly more frequently found in 19-year-old girls than in boys. No consistent pattern of relationships between reported and recorded clicking sounds and single factors obtained by the questionnaire or clinically recorded variables could be found. Palpation tenderness in three muscle sites was to a varying degree related to both reports and recordings of clicking. Each year, significant relationships were found between reports of TMJ sounds and symptom indices. Recorded sounds were significantly related to a clinical index in the two oldest age groups. The prevalence of TMJ clicking sounds increases with age, and girls are more prone to have them than boys. In view of the natural longitudinal fluctuations, most clickings only need to be supervised, and when there is a demand for treatment, reversible methods are advocated in adolescents.

Craniomandibular disorders in an urban Swedish population.

A sample of 637 persons was interviewed and examined clinically for signs and symptoms of CMD. Five percent reported daily headaches, and recurrent headaches were more frequently (P less than 0.001) reported by women (28%) than men (15%). Women more often (P greater than 0.001) had headaches upon awaking and in the afternoon. Face, eyes, throat, and neck were the most common locations of pain (20%). Women (18%) more often (P less than 0.05) reported CM symptoms than men (10%), and 16% of the women and 9% of the men considered themselves to be in need of treatment. About 20% reported oral parafunctions (clenching/grinding/biting). The most frequent clinical finding was TMJ sounds (58%). Both clicking and crepitation were more frequent in women (P less than 0.01). Palpation tenderness in the jaw muscles was most frequently found in the lateral pterygoid (34%) and temporal muscle (27%). Women generally had more tenderness and muscles tender to palpation. Mean maximal opening capacity was significantly larger in men. Only 12% of the sample were found to be free of signs of mandibular dysfunction. As signs and symptoms of CMD were common findings, routine dental examination should always include functional examination of the stomatognathic system to evaluate the need of treatment.

Craniomandibular disorders in adult populations of West Bothnia, Sweden.

A randomly selected sample of 1992 adults (995 men and 997 women) representing four equally sized age groups of 25-, 35-, 50-, and 65-years-old inhabitants of West Bothnia were studied for prevalence of symptoms and clinical signs of mandibular dysfunction. Of the sample 79% completed a questionnaire and a clinical examination. The chewing inability increased with age. Recurrent headaches (once a week or more often) were reported to occur in 11% to 15% of the four age groups, and the duration of headaches was generally more than 2 years. Tooth-clenching, which was the most frequent oral parafunction, was reported significantly more often in women, whereas attrition was more severe in men. The commonest clinical finding was temporomandibular joint clicking, which varied between 13% and 35% in the different age groups. Crepitation was observed more often in women and increased with age. The jaw muscles were more frequently tender to palpation in women and the elderly. The mean maximal mouth opening capacity varied between 55 mm and 44 mm, decreasing with age, and was for the whole sample significantly higher among men. Since signs and symptoms of craniomandibular disorders were common findings in all age groups, routine dental examination should always include functional evaluation of the stomatognathic system.

Frequency of occlusal interferences: a clinical study in teenagers and young adults.

Contact relations between the teeth in the lower and upper jaws in the retruded position and on the nonfunctional side were investigated in two different age groups with mean ages of 15 and 22 years, respectively. The subjects had no complaints of mandibular dysfunction. The relations on the nonfunctional side were registered in four different positions of the mandible. Unilateral tooth contacts in the retruded position were found in 75% of the persons in both age groups. Lateral displacement of the mandible of 0.2 mm or more in sliding from RP to the IP occurred in 34% in the younger group and in 66% of the adults. Contacts on the balancing side at the four different lateral positions were found in 6% to 13% among the teenagers and in 9% to 25% among the adults. Balancing interferences, which appeared in 5% to 10% of the persons in both age groups at 3 mm lateral movement, increased 5% to 11% between each one of the other positions registered. These interferences reached a level of appearing in every three to four persons at maximal lateral movement of the mandible. No less than 88% and 89%, respectively, of the individuals in both age groups had at least one occlusal contact, usually defined as an interference, in one or more of the nine registered positions of the mandible. Because the subjects had well-functioning masticatory systems, this study does not support the opinion that the mere presence of occlusal interferences is of major importance in the etiology of mandibular dysfunction.

Bite force after temporomandibular joint surgery.

Bitings were recorded bilaterally on 5 different submaximal and maximal force levels on 12 patients (7 women and 5 men) who had earlier been subjected to TMJ surgery (10 diskectomies and 2 condylectomies). The maximal bite force was relatively low for the recorded sample with mean values of 7.8 Kp and 8.3 Kp for operated and non-operated sides, respectively. The strongest forces were recorded after condylectomy. There was a wide range between the individual recordings on all levels and the differences increased with the force and were largest at maximal bite force level. No significant differences in bite force between operated and non-operated sides could be found for any of the force levels. The ability to discriminate between different force levels was better on the higher levels. The almost comparable results of the recordings of bite force on the operated and the non-operated sides may be an effect of functional interaction within the masticatory system and be an expression of the essentially improved function after the surgical treatment.

Signs and symptoms of mandibular dysfunction in patients with suspected oral galvanism.

Fifty-four consecutive patients were examined by means of a self-administered questionnaire with questions related to general health and subjective symptoms. In addition, a clinical stomatognathic evaluation was carried out including palpation of the temporomandibular joints (TMJ) and the masticatory muscles and functional analysis of occlusion and mandibular mobility. High frequencies of general diseases were reported. The dominant subjective symptom was headache (62%), which often appeared daily. Symptoms such as pain from the teeth, pain in the face/jaws, and burning sensations in the tongue or oral cavity all appeared in more than half of the sample. The patients were frequently aware of parafunctions such as clenching of the teeth and tongue press. None of the investigated persons were completely free of clinical signs of dysfunction. The most frequent clinical finding was palpation tenderness in the masticatory muscles (96%), generally located in the masseter, temporal, and lateral pterygoid muscles. In more than half of the material TMJ findings were recorded, and more than one-third had TMJ pain. In 35% mandibular mobility was reduced. Occlusal interferences on retrusion and on the mediotrusion side were frequent findings. Impaired general state of health and multiple signs and symptoms of mandibular dysfunction were thus frequent findings in these polysymptomatic patients. Three-fourths of the patients needed treatment for mandibular dysfunction, indicating that great consideration must be made for the functional status of the masticatory system in clinical evaluation of so-called 'oral galvanists'.

Discomfort and bite force in painful masseter muscles after intramuscular injections of local anesthetic and saline solution.

Thirty women with a history of daily pain in the masseter muscles were injected with either lidocaine or saline. The participants were told that they were being given an anesthetic injection to reduce their muscular discomfort. The dentist performing the injections did not know which fluid was used. The discomfort in the masseter muscle was assessed by using Borg's new rating scale before and 10 minutes after injection. The evaluation was followed up on day 1, day 3, and day 7. Bite force was registered between the first molars on the injection side. When scale values were compared individually within groups before and after injection, a significant decrease in discomfort was found in both groups, with the exception of day 1 for the lidocaine group and days 1 and 3 in the saline group. The total lidocaine and saline groups assessed the discomfort similarly except on day 3 when the lidocaine group showed significantly less discomfort. The intraindividual force values increased significantly after injection in the saline group. This effect was not found in the lidocaine group. Despite the minor tendencies for lidocaine to have a better effect, the placebo effect was considered to be high and important.
