Comparison of arthrographic findings of the temporomandibular joint with palpation of the muscles of mastication.

Two hundred five patients were examined for temporomandibular joint pain and dysfunction and specifically for tenderness to muscle palpation. Arthrograms were performed on 222 joints (188 unilateral and 17 bilateral). Significant findings were ascertained for the middle portion of the temporal muscle in "normal" patients versus "with and without meniscus reduction" patients. The superficial masseter muscle was more tender in "normal" patients and in "reducing meniscus" patients than in "without meniscus reduction" patients. The medial pterygoid muscle was more tender in "normal" patients and in "without meniscus reduction" patients than in "reducing meniscus" patients. Though there are some significant findings with respect to muscle palpation, by itself muscle palpation is not a specific indicator of temporomandibular joint internal derangement.

Clinical and arthrographic evaluation of the location of temporomandibular joint pain.

Two hundred five patients were prospectively examined for temporomandibular joint pain. Arthrograms were performed on 222 joints (188 unilateral and 17 bilateral). Pain in the ear occurred more frequently in arthrographically normal patients and in nonreducing meniscus patients compared with reducing meniscus patients. The location of pain in front of the ear, in the temples, or in the neck or the degree of pain intensity did not correlate to specific meniscal abnormalities. No correlation between the distribution and the character of headaches was observed. Pain characterization alone does not clinically separate meniscal abnormalities.

Use and quality of bitewing films in private dental offices.

Patient records (387) were obtained from twenty-five dentists in private practice in Rochester, New York. The number and types of radiographs taken at each recall examination in the most recent 10-year period were recorded. Bitewing radiographs were taken at 50.5% of the recalls with size 2 film used most frequently (83.7%). The average recall interval was 8.4 months overall and 18.0 months for bitewing recalls. Of all proximal surfaces available on the bitewing films, 68.2% were judged adequately separated for diagnostic purposes. For individual surfaces, the highest percentages were recorded for the mesial surface of the maxillary second premolar (89.9%) in the permanent dentition and for the distal surface of the mandibular second molar (83.7%) in the deciduous dentition. Taking four bitewing films instead of two improved the percentage of adequately separated proximal surfaces at a given recall by 2% to 25%. The percentage of unreadable proximal surfaces caused by overlapping or distortion on the bitewing radiographs, when excluding the canines, ranged from 6.3% to 39.5% in the permanent dentition and from 12.5% to 24.9% in the deciduous dentition.

Bitewing radiographs and dentists' treatment decisions.

A study involving twenty-one general dentists in private practice in Rochester, New York, was performed to assess the relationship between radiographic evidence of caries and restorative intervention in permanent teeth. Seven thousand three hundred thirty-eight bitewing radiographs taken of 387 patients over the most recent 10-year period were obtained and independently examined by six Eastman Dental Center faculty members as to presence of restorations and caries status of nonrestored proximal surfaces. Patients 20 years of age and younger had significantly lower mean maximum caries penetration scores before restorative treatment when compared to older patients. For all age groups, the mean maximum caries penetration scores indicated that, on the average, restorative treatment was initiated before there were radiographic changes in dentin. There were no differences among the dentists in the study regarding the mean elapsed time between radiographic caries diagnosis and restorative treatment. The random distribution and low number of apparent caries reversals, and the subsequent restoration of 25% of these teeth, suggested that the dentists in this study did not employ systematic remineralization strategies for their patients.

Comparison of internal derangements of the TMJ with occlusal findings.

Two hundred five patients were examined because of temporomandibular joint pain and dysfunction. Arthrograms were performed on 222 joints (188 unilateral and 17 bilateral). No significant differences were found between arthrographic groups with respect to Angle classification, horizontal and vertical overlap, posterior tooth wear, missing posterior teeth, cuspid-protected occlusion, balancing-side contacts, deflective occlusion, and clenching of the teeth. Tilted teeth on the contralateral side were more common in cases of reducing meniscal dislocation than in cases of normal meniscus position or of nonreducing meniscal dislocation.

Retention of sealants over carious and sound tooth surfaces.

Bacteriologic and clinical studies suggest that sealants can be used therapeutically on incipient caries of the enamel. The present study was designed to explore this approach further by determining whether there is a difference in retention rates on sound or carious tooth surfaces sealed for the first time as well as resealed surfaces. A total of 1766 teeth were sealed for subjects 12-14 yr of age of which 120 were judged to be carious. Mouths were divided sagittally on a random basis and an ultraviolet light activated resin with a filler or an autopolymerizing resin without a filler was placed on contralateral surfaces of all molar and premolar teeth. The effects of sealant type, caries status, arch and tooth type on retention over a 2-yr period were tested using Mantel-Haenszel statistics. At the end of 1 yr, 88% of the teeth sealed with the autopolymerizing resin were judged to be completely intact compared to 82% of the teeth filled with the ultraviolet light resin. At the end of the second year the retention rates were 84% and 75% respectively. The retention rates for carious and sound teeth at the end of both years were almost identical. Overall, premolars had a 15% more favorable retention rate than molars. There were minimal differences between arches although maxillary premolars had approximately a 5% higher retention rate than mandibular premolars. The reverse was true for molar teeth. Retention of sealants at the end of the second year (resealed after 1 yr) was 4% less than comparable teeth sealed initially.

Prevalence of drugs causing hyposalivation in an institutionalized geriatric population.

The types and numbers of drugs prescribed for nursing home residents were enumerated in order to determine the prevalence of drugs that cause hyposalivation. Drugs were coded as having a definite or probable hyposalivatory side effect, or as having no effect, and were also categorized by therapeutic action. The average number of drugs prescribed for each patient was approximately four. Approximately half of the institutionalized elderly received one or more drugs with a hyposalivatory side effect. The hyposalivatory drugs were mainly antipsychotics, antidepressants, antihistamines, and analgesics.

Clinical and arthrographic evaluation of temporomandibular joint sounds.

Two hundred five patients were examined for temporomandibular joint pain and dysfunction. Arthrograms were performed on 222 joints (188 unilateral and 17 bilateral). Patients with joint sounds suspected of being caused by meniscus displacement with reduction were evaluated. Seventy-two patients (38%), were suspected of "clicking" (a reducing meniscus), but only 53 had arthrographic findings of a reducing meniscus. Further evaluation of this patient group revealed that only 41 probably could be candidates for a protrusive splint. This represents only 57% (41 of 72) of patients with "clicking" who may be candidates for protrusive splint treatment.

Clinical radiographic evaluation of sealed carious and sound tooth surfaces.

The results of a 2-year radiographic assessment of 113 carious posterior teeth that were sealed with one of two sealants are presented. Little or no difference was found in radiographic ratings of caries by type of sealant. Sealant loss between annual recall visits had little or no detectable effect on radiographic ratings of caries during the study. Radiographs suggested that caries may regress in sealed teeth with early caries. The results support the safety of sealing incipient caries in pits and fissures to increase the potential uses of sealants.

Mandibular range of motion versus arthrographic diagnosis of the temporomandibular joint.

The range of mandibular movements has been correlated with arthrographic findings of the temporomandibular joint in 205 patients. Abnormalities of meniscus position and function have been found to influence mandibular movements in characteristic patterns. However, altered mandibular movements alone are insufficient for a definitive clinical diagnosis of the specific type of internal derangement of the temporomandibular joint.

Effects of fluoride, lithium, and strontium on intracellular polysaccharide accumulation in S. mutans and A. viscosus.

Fluoride (5 mg/l) consistently depressed the accumulation of intracellular iodophilic polysaccharides (IPS) in Streptococcus mutans strains BHT, FA-1, and GS-5 by over 90% and in Actinomyces viscosus strain RC-45 by over 50%. There was little further reduction in IPS content when fluoride was increased from 5 to 100 mg/l. Lithium (0 to 1 mg/l) neither enhanced nor inhibited IPS accumulation, nor did it modify the inhibitory effects of fluoride in three of the four strains tested. Strontium (0 to 100 mg/l) did not alter IPS accumulation in S. mutans GS-5 but decreased accumulation (less than 10%) in S. mutans FA-1 and BHT and significantly enhanced IPS accumulation in A. viscosus RC-45. Analysis of variance indicated no statistically significant interactions between fluoride and strontium, fluoride and lithium, or strontium and lithium.
