AbstractThe purpose of this study was to evaluate the separate effect of fluoride dentifrice, fluoride mouthrinsing and fluoride varnish on approximal dental caries. All 252 13–14‐yr‐old children at an elementary school were selected al random and divided among four groups for a 3‐yr longitudinal study. Group 1 received a fluoride dentifrice for home care and a fluoride mouthrinse once a week. Group 2 received a fluoride dentifrice for home care and a placebo mouthrinse once a week. Group 3 received a fluoride dentifrice for home care and a fluoride varnish once every 3 months. Group 4 received a placebo dentifrice for home care and a fluoride rinse once a week. Fluoride rinsing did not give any additional effect compared with placebo‐rinsing when a fluoride dentifrice was used for home care. Fluoride varnish gave a significant caries reduction compared with fluorid

摘要:

AbstractData from a survey of 3727 14‐yr‐old children from 31 secondary schools in England in 1984–85 were analysed to obtain information about tooth brushing frequency, social group, number of siblings, and time of going to bed. Subjects completed a questionnaire, anonymously, in class. One third of respondents cleaned their teeth once or less per day. Tooth brushing frequency was found to increase significantly with improvement in social status in males (P<0.05), while a similar non‐significant trend was found in females. Tooth brushing frequency decreased significantly as the number of siblings increased (P<0.01) and a trend towards decreasing brushing frequency as bedtimes became later was observed. These findings indicate that family factors do influence tooth brushing practice in adolescents. These factors need to be understood more thoroughly if tooth brushing habits in school‐age children are to be

摘要:

AbstractDietary factors related to dental caries may be both biological and behavioral. In the present study the relative contribution of a number of behavioral characteristics is analyzed in order to differentiate between caries‐active (CA) and caries‐inactive (CI) children. The study group comprised 49 CA and 55 CI 14‐yr‐old Danish children, constituting the dichotomous dependent variable. Several variables related to the social and cultural context in which food and snack consumption takes place were studied. Subsequently, their relative contributions to the discriminant function (CA vs. CI) were estimated using discriminant analysis. The three strongest discriminating variables were “weekly milk consumption” (−0.726), “packed lunch from home” (0.554), and “weekly consumption of candy in DKK” (0.306) as measured by standardized canonical discriminant function coefficients. These variables may be indicative of the impact of the social environment on dietary habits, pointing to the need for incorporating the social network as reinforcing agent in dietary counseling if dietary beha

摘要:

AbstractThe dental needs, demands and patterns of service utilization were assessed in a randomly selected sample of 750 subjects attending the Dental Faculty, University of Malaya, Kuala Lumpur. Toothache accounted for the most frequent overall dental complaint. However, the most common motives for seeking dental care varied among children (2–12 yr), adolescents (13–18 yr) and adults (19 + yr). The attendance behavior of women is more preventively orientated and more inclined towards rehabilitation compared to that of men. The proportion of normative needs of the patients varies from 7.5% for dentures to 66% for dental caries. About 50% of service utilization for the first visit consisted primarily of extractions in the oral surgery departm

摘要:

AbstractThe treatment times for the fabrication of Extensive Amalgam Restorations (EAR) as recorded in a longitudinal clinical trial at the Dental School in Nijmegen were analyzed. 269 EAR's with different retention methods were made on molars by three operators. A mean total treatment time of 60 min was found. The factor operator had a significant influence on all treatment phases resulting in a 26% difference in total treatment time between operators. Also significant influences were found in some treatment phases for the factor retention, side location of the tooth and extension of the restoration. The results of this study with regard to treatment times must be considered from the perspective of the quality of the care provided.

AbstractThe potential ocular hazards associated with the use of dental curing lights were evaluated. Recommendations are provided for precluding exposure of personnel to hazardous levels of optical radiation. Users should not stare directly into the dental curing lights at distances shorter than 25 cm (which would not be a likely event).

摘要:

AbstractThe use of the life table method for assessing the longevity of dental restorations is growing. One reason for this is the availability of statistical computer packages which can be used by the non‐expert, and this is tending to lead to an uncritical approach to the methodology. Although much can be learnt regarding the durability of restorations by using life table analysis, there are many inherent problems related to its use in dental studies. The survival pattern of many restorations is such that long‐term studies are required to obtain valid assessments of durability. Results reported after only a few years of study contain many restorations not followed to failure. The ways in which data on these restorations are handled can greatly affect the estimates of longevity. These considerations have not, to date, received sufficient attent

摘要:

AbstractThe aim of the present study was to compare the results obtained using two different methods of data collection about caries preventive services provided in general dental practice. A questionnaire was mailed to a random national sample of 479 dentists resident in Norway in January 1985. The sample was divided into two groups by random allocation. All dentists, irrespective of group, were requested to give background information. One group, comprising 287 dentists (OR), was asked to complete a separate form for every adult patient (≥20 yr) treated in the course of 1 day. The demographic characteristics and dental visiting habits of the patients, as well as the number of teeth present, caries lesions and preventive services rendered were recorded. The other group, 192 dentists (GE), was requested to make general estimates of the time spent on caries prevention and the proportion of patients receiving various types of caries preventive services. The dentists were unaware of the methodologic aspect of the survey and everyone received one reminder in order to guarantee anonymity. The estimation method (GE) did not give the expected advantage over the registration method (GR) in response rate (51.7% vs 46.2%,P>0.40), and gave a gross overestimation of the frequency with which adult patients received different types of caries preventive procedures (P<0.005). Thus, even though the estimates of the proportion of total treatment time spent on caries prevention were comparable for the two methods, and the estimation approach is labor‐saving, it cannot be recommended for the collection of data on caries prevention in the dental off

摘要:

AbstractAssessment of denture quality is important in prosthetic research. The aim of this investigation was to determine the intra‐ and inter examiner reliability of denture quality assessment. Three groups of patients with full maxillary and mandibular dentures and two dentists participated. The patients in group 1 (n= 195) were examined by the two dentists independently, in group 2 (n= 35) twice by one of the dentists and in group 3 (n= 20) twice by the other dentist. A denture quality scale was constructed containing nine variables. The internal consistency (coefficient alpha) of this scale was 0.60. The intra‐ and inter examiner reliability was between 0.59 and 0.86. For individual items of this scale these values were between 0.22 and 1

摘要:

AbstractA representative sample of 1650 children randomly selected in the 6–15‐yr‐old schoolchild population of Strasbourg was examined by well‐calibrated examiners. The prevalence of caries was determined with the DMFT, DMFS and dft indices using bitewing radiographs. Plaque, calculus and gingival indices were also determined. The results obtained were compared with the initial study of 1974 performed in Strasbourg using the same epidemiologic methods. Whereas no important variations were observed in caries prevalence of primary teeth, a significant reduction of caries activity was observed in DMFT and DMFS indices in all age groups. There was a reduction of these two indices of respectively 32% and 33% in the 12‐yr‐old children. The reduction was the most significant on approximal surface lesions. A statistically significant decrease of the calculus and gingival indices was also observed between 1974 and 1984. A less significant decrease was observed for the p
