摘要:

AbstractThe effect of a preventive program was studied in Polish schoolchildren. The study was carried out in a group of 133 children, aged 10–12 yr, divided into a teat and a control group. Children in the test group were initially treated with temporary restorations and were then given oral health education and preventive treatment by a specially trained chairside assistant. The preventive treatment included prophylaxis and topical fluoride treatment and was carried out at least 10 times a year. The mean 3–yr DFS increment was 1.7 in the test and 10.9 in the control group at baseline and after 1 and 2 yr. At the examination after 3 yr, a difference was established between the two gro

摘要:

AbstractA group of 71 patients was examined to determine the longevity of restorations placed at the University of North Carolina School of Dentistry. Patients with an overall restorations failure rate of equal to or greater than 40 per 1000 restoration‐yr were categorized as having a “high failure rate” and those below that were considered “low failure rate”. An investigation was made to determine statistical differences between these two groups of patients using survival analysis and various statistical indices. Time of exposure and age of patients for both groups were similar. High rate patients had a greater number of anterior restorations and anterior teeth restored. In addition, the number of restorations per tooth was significantly greater in anterior and posterior teeth of the high failure rate group. No single variable was found to account for the differences in the failure rates in the two groups of patients. A prospective study is needed in order to examine possible causes for restoration

摘要:

AbstractNo formal analyses comparing the treatment alternatives of replacing a failed amalgam with either another amalgam or crown have been done to determine the optimum treatment strategy based on lifetime costs to the patient. Using decision analysis, a computer model was developed of the lifetime restorative needs of an adult's posterior tooth. A cost‐effectiveness analysis of large amalgams vs crowns was then done to determine the optimum strategy. According to the analyses, the optimum treatment decision is to attempt to replace the failed first amalgam with another amalgam, instead of with a crown. When this amalgam restoration fails, then the subsequent replacement may be with a crown. Potential lifetime cost savings were between 11% and 24% if the first replacement was an amalgam. This study concludes that the technique of decision analysis provides the dental community with an effective evaluation tool for the study of clinical decision‐making, taking into account all levels of clinical uncertai

摘要:

Abstract234 dentists and dental nurses were examined with a normal and a high‐frequency audiometer in high standard clinical conditions. Their ordinary and high‐frequency hearing as compared with the controls showed no significant differences. Thus, exposure to high‐frequency noise from high‐speed drills and other modern dental instrumentation does not appear to be harmful to one's hearing and does not necessitate audiologic screening procedures for dental pe

摘要:

AbstractThe oral health of subjects over 75 yr and living independently in the southwest of Britain was assessed. The majority (80%) of the sample were edentulous, and a large proportion of both edentate and dentate subjects were using dentures. More than half of the denture wearers were using loose, very unhygienic, or structurally defective dentures. Mucosal pathoses were quite common, although most of the lesions were denture‐induced stomatitis found in association with unhygienic dentures. The dentate subjects had, on average, 11 natural teeth, frequently with evidence of root caries and deep periodontal pockets or extreme bone loss. The oral health problems suggest that there is a significant need to develop effective methods of improving oral hygiene in this age group. The prosthetic treatment is related principally to denture repairs while there is a need to control root caries among the growing population of elderly dentate peopl

摘要:

AbstractThe aim of this study was to measure the relative importance of a number of psychologic and social variables in explaining the severity of symptoms of functional disturbances of the stomatognathic system. 261 non‐care seeking patients with respect to pain and dysfunction of the stomatognathic system were examined. The total sample consisted of two subgroups: Group 1 (n= 130) with a complete natural dentition and Group 2 (n= 131) wearing complete maxillary and mandibular dentures. Symptoms of functional disturbances of the stomatognathic system were assessed using two questionnaires. One was derived from the Anamnestic Dysfunction Index and the other was an extended questionnaire which included accessory symptoms frequently mentioned in the literature. The patients also completed the Hopkins Symptom Checklist, the Dutch Personality Inventory, and a Dutch form of the Minnesota Multiphasic Personality Inventory. In both patient subgroups symptoms of functional disturbances of the stomatognathic system were significantly correlated with patient's sex and a complex of highly intercorrelated psychologic variables: psychoneurotic‐ and somatic symptoms, neuroticism, negativism, and somatizat

摘要:

AbstractThe relationship between dietary, dental health behaviors, and other health‐related behaviors was studied using factor analysis. The study group comprised 234 8th graders from 11 schools in the municipality of Aarhus. A semi‐structured interview included 12 items of health behavior (e.g. sugar intake, meal pattern, sports activities, sleeping habits, and consumption of alcohol, cigarettes, vitamin pills, candy, and milk). The analysis is based on the assumption that the 12 observed variables are determined by a reduced number of underlying but unobservable factors. Four dimensions of health behavior which explained 38.6% of the variance between the variables were produced. The four unrotated factors accounted for a varying proportion of the total variance (17.6%, 11.8%, 4.4% and 4.3%, respectively). Factor 1 was denoted “Sugar behavior”, factor 2: “Regularity of dietary‐behavior”, factor 3: “Problem behavior” and factor 4: “Spare‐time activity”. This could imply that the motives underlying sugar consumption are different from those of other health‐related behaviors. The present behavioral pattern is consistent with that of other studies in which health behavior has been sho

摘要:

AbstractThe aim of this investigation was to compare dietary habits, plaque and gingival scores, and the dental caries prevalence of 16–yr‐olds in 1979 with those of individuals of the same age 5 yr later, i.e. in 1984. Students from two high schools in Kristianstad, Sweden, participated, 273 in 1979 and 228 in 1984. The same two dentists treated the children in 1979 and 1984. The students were asked to fill in a questionnaire concerning breakfast, school‐lunch and between‐meal habits. Information about the number of decayed (D) and filled (F) approximal tooth surfaces (Sa), DFSa, dental plaque and gingival bleeding scores was obtained from records at the Public Dental Clinics. The prevalence of caries lesions was also determined on 116 and 110 randomly selected pairs of bitewing radiographs from the participants in 1979 and 1984. respectively. The mean DSawas 0.9 in 1979 and 0.3 in 1984. The corresponding values for FSawere 3.6 and 1.5, respectively. In 1979, the DFSawas zero in 28% of the children, compared to 54% in 1984. All these differences were statistically significant (P<0.05). When analyzing the distribution of enamel and dentin caries lesions diagnosed on radiographs, the same tendency was found, i.e. that dental health had improved from 1979 to 1984. The dietary habits, however, were on the whole the same on both occasions, as judged from the answers given in the questionnaire. The distribution of plaque and gingival scores did not change during the 5‐yr period. The main conclusion from this study is therefore that other factors than improved dietary habits and oral hygiene must have contributed to the obvious reduction of caries prevalence in these groups of high school

摘要:

AbstractA pilot oral health epidemiological survey using WHO assessment forms was conducted in Yugoslavia in the year 1986. The study population consisted of 2600 persons aged 6, 12, 15, 18, 35–4, and over 65 yr. The survey included 22 towns (11 developed and 11 underdeveloped) in the six Republics and two Provinces of Yugoslavia. The results showed the prevalence of dental caries in the Yugoslav population to be very high (98.7% in 12–yr‐olds). The mean decayed, missing, and filled teeth (DMF) scores were as follows: 6.1 at age 12 yr, 9.6 at age 15, 10.9 at age 18, 18.0 at age 35–44, and 28.0 in persons aged over 65 yr. Assessment of the periodontal status showed calculus to be the predominant disorder in the age groups 18 and 35–44 yr, while loss of sextants prevailed in persons aged o

摘要:

AbstractThe caries prevalence (dmft) and severity (ess) in 3‐, 4‐, and 5‐yr‐old children in South Africa were examined. Four levels of S. mutans in the saliva of 228 of these children was estimated by the spatula method. In all three age groups a statistically higher dmft and css was found with a S. mutans level of>106CFU/ ml in saliva than at lower concentrations. At age 5 ANOVA showed significant differences between dmft and css at all S. mutans levels. A high concentration of S. mutans in the saliva may be an indicator of the high risk child at an ea
