摘要:

Twenty-two patients (29 joints) with temporomandibular joint (TMJ) arthritis of specific or unspecific nature were given one intra-articular glucocorticoid (GC) injection. The effect on subjective symptoms and clinical signs in the craniomandibular system and on joint aspirate concentration of neuropeptide Y-like immunoreactivity (NPY-LI) was evaluated at follow-up visits 2-3 or 4-6 weeks after treatment. In the patients with specific inflammatory joint disease the treatment resulted in an improvement of symptoms and clinical signs and in a reduction in the TMJ level of NPY-LI 2-3 weeks after treatment. In the patients with unspecific inflammatory joint disease there was also an improvement in the clinical variables and a reduction in the NPY-LI level after 2-3 weeks, but not on a statistically significant level. The results of this study show that intra-articular GC treatment causes a short-term decrease of the TMJ fluid level of NPY-LI in patients with specific inflammatory joint disease, while symptoms and signs improve.

摘要:

The laser fluorescence method (LAF) was validated with longitudinal microradiography (LMR) for assessment of mineral loss in incipient caries lesions inhuman enamel. Fluorescence radiance scans and LMR recordings were made of 36 enamel slabs with incipient lesions. Original sound values for fluorescence radiance and enamel amount (kg·m-2) at the lesion site were reconstructed by a computer algorithm. Changes in fluorescence radiance and amount of enamel in each measuring point were calculated. The reconstruction method was tested on 20 sound enamel surfaces. The differences between measured and reconstructed values were -0.13±0.17% with LAF and 0.002±0.005 kg·m-2with LMR. The repeatability of the caries quantification was tested by measuring one lesion 20 times. The fluorescence loss in this lesion was 18.2±1.0%. The enamel loss was 0.09±0.02 kg·m-2. The correlation between measurements with the two methods wasr= 0.73. The non-destructive laser fluorescence method was concluded to be a sensitive and valid method for quantification of mineral loss in enamel caries lesions.

摘要:

Sixteen individuals with rheumatoid arthritis (RA) and 19 individuals with ankylosing spondylitis (AS) participated in this 3-year follow-up study. The individuals in each disease group were allocated to an experimental group (E group) and a comparison group (C group). They were investigated by questionnaire, clinical examination of the stomatognathic system, and laboratory tests. The individuals of the two E groups had performed a physical training program of the stomatognathic system during 3 weeks. After 3 years most of the patients in the E groups reported an unaltered or decreased severity of symptoms and signs from the stomatognathic system compared with the initial status. The clinical dysfunction score according to Helkimo (CDS) was lower in the RA group, and the mouth opening capacity was larger than before training. In the AS group there was no long-term change in the CDS but an increase of mouth opening capacity. The general inflammatory disease process in the RA group showed an increased activity during this follow-up period as assessed by erythrocyte sedimentation rate. This study suggests that local physical training of the stomatognathic system has a positive effect in individuals with RA.

摘要:

The bonding strength of two glass ionomers, a resin-modified and a conventional one, to dense synthetic hydroxyapatite (HA) and fluoroapatite (FA) ceramics was compared by measuring the shear strength between the ionomers and the apatites. Before the glass ionomers were applied on the apatites, the surfaces of HA and FA plates were either fine-polished or acid-etched after fine polishing. Commercially pure titanium (CP Ti) plates were used as a control. The effects of polyacrylic acid (PAA) surface preconditioning on bonding strength were also studied. The results show that the ionomers bind to HA significantly more strongly than to FA in all cases. The resin-modified material showed a significantly higher shear strength to apatites than the conventional one. Acid etching increased the shear strength significantly for the conventional glass ionomer to both HA and FA, and 25% PAA preconditioning increased the shear strength significantly for the resin-modified glass ionomer to both HA and FA. It was concluded that glass ionomers seemed to bind to apatite chemically, and the bonding strength was influenced by the cohesive strength of the ionomers and the surface roughness of the apatites. The dense synthetic apatites seemed to be good test materials for bonding evaluations of glass ionomers to mineral tissue.

摘要:

A retrospective study of patients hospitalized for complications after third-molar surgery during a 10-year period showed that of the total 19 cases, 15 presented as infections. Five admissions were attributable to surgery performed by oral surgeons, including two cases of postoperative bleeding, two infections, and one displaced root fragment. Fourteen patients admitted after surgery by general dental practitioners included 12 acute and 2 chronic infections. Apart from daily smoking, no medical problems or other risk factors were associated with the complications. According to assessments of regional volume of third-molar surgery by general dental practitioners and oral surgeons, the rates of serious postoperative infections were 2.8·10-4and 6.5·10-3cases per operation, respectively. This difference in infection rates may be explained by less surgical training and experience in general dental practice.

摘要:

The aims of the analysis were 1) to examine the development in utilization of dental care provided for adults in Denmark under the National Health Insurance during the period 1975-90; 2) to assess the appropriateness of available dental care statistics for studies of oral health trends; and 3) to analyze the price development of dental services during 1975-90 and its impact on patient and Insurance expenses, respectively. Utilization and economic data were retrieved from available registers and analyzed. Three trends were found. First, the utilization has increased more than what could be explained by the population increase; secondly, the panorama of dental services changed from predominantly restorative/extraction services to predominantly diagnostic/preventive services. Thirdly, the price paid by Danish adults for dental care increased disproportionately to other price developments in society. On the basis of traditional health economic theory this development could be expected to affect demand for dental services negatively.

摘要:

The aims of this study were 1) to analyze changes in and determining factors for demand for dental care among Danish adults during 1975-90, and 2) to apply standard cohort analysis on sequential cross-sectional survey data, thereby enabling the separation and examination of age, period, and cohort effects. Samples of non-institutionalized Danes aged 15 years and more were interviewed in 1975 (n= 1204), 1980 (n= 1108), 1985 (n= 1123), and 1990 (n= 1003), in accordance with a standardized questionnaire. Overall demand for dental care increased from 59% in 1975 to 76% in 1990; the younger the respondents, the higher the demand- Standard cohort table analysis indicated that the main effect derived from cohort succession; that is, the higher demand of the new cohorts entering the population remained higher than that of previous cohorts. Logistic regression analysis indicated that from 1980 to 1990 the significant predictors for regular dental care shifted from being predominantly predisposing and need variables to predominantly enabling and need variables.

摘要:

The effect of a vegetarian diet on oral health status could be manifold, but reports have so far mainly appeared from within Western populations. This study reports the oral health status of southeast Indian vegetarians, obtained by means of a questionnaire, clinical examination, and study cast evaluations. The material comprised 30 vegetarians and 25 sex- and age-matched non-vegetarian controls. Comparison between the samples included dietary and oral hygiene habits, health-related variables, caries prevalence, and dentoalveolar characteristics. The questionnaire showed significantly less consumption of between-meal sweets and more widespread use of a soft toothbrush by the vegetarians. The vegetarians had a significantly higher degree of tooth wear than the non-vegetarians, but no difference in the degree of wear between women and men in either group was found. The vegetarians had a significantly higher tendency towards crowding in the maxillary arch, numerically higher DMFT, and greater number of cervical buccal defects than the controls. The results of this study suggest that the Indian vegetarian diet may produce certain effects on the oral health, associations that need to be studied further.

摘要:

The present epidemiologic dental caries study indicates a high number of decayed surfaces (mean, 13.5±11.8 (SD)) in a Portuguese population of 30- to 39-year-olds from Porto. The most influential determinants for variation in carious surfaces were oral hygiene, gender, salivary buffer capacity, and missing teeth. By entering the most influential independent variables in a final multiple classification analysis, the total explained variance in carious surfaces was 27%. A comparison with results from a similar Norwegian dental health study showed that the biologic factors of importance for number of carious surfaces were the same, whereas the sociocultural determinants differed.

摘要:

The flexure strength of three resin-modified glass ionomer cements and one conventional glass ionomer cement and their bond strength to dental composites were studied by measuring the three-point bending and the shear strengths. The bond strengths between the dental composite and the resin-modified glass ionomer cements were dependent on the curing modes. Resin-modified glass ionomer cements bonded significantly more strongly to cured dental composites than dental composites bonded to cured resin-modified glass ionomer cements. However, the dental composites showed a significantly stronger bonding to the resin-modified glass ionomer cements than to the cured conventional glass ionomer cement, to which the dental composite did not adhere without acid etching. The flexure strengths of the resin-modified glass ionomer cements were significantly improved compared with the conventional one but were still significantly lower than that of the dental composites.
