摘要:

AbstractDental caries remains a prevalent, chronic disease of childhood. The preponderance of dental caries is located on the pit and fissure surfaces of teeth, an area where dental sealants are most effective in preventing this malady. In the school year 1987‐88, 4,879 Ohio schoolchildren participated in an assessment of dental health. Grades chosen for this assessment included 1, 2, 3, 6, 7, 8, and 11. This study focuses on eruption of first and second permanent molars in development of a timing strategy for placement of occlusal sealants in a school‐based program. An eruption score was developed for the determination of the first or second molar eruption status for each child. The data were analyzed for grade, sex, race, locale, fluoridation status, and percent of children on free or reduced‐cost lunch programs. Analyses were performed on 2,215 children in grades 1‐3 and 1,840 children in grades 6–8. Fifty‐seven percent of first graders had all first permanent molars sufficiently erupted for sealant placement on the occlusal surface. Likewise, 23.6 percent of sixth graders had sufficient occlusal exposure on the second molar. Females showed an earlier eruption pattern than males for both first (P<.05) and second (P<.001) molars. Black children preceded white children only in the eruption of the second molar (P<.001). This study provides dental public health decision makers with state‐specific information on the earliest time to initiate a school‐based occlusal sealant program. Information on caries experience is warranted to determine whether or not there can be a delay in performing this service so that more individual teeth can have dental

摘要:

AbstractPrimary canine hypoplasia is an incomplete or defective development of the enamel matrix. The lesion is located on the labial surface and is seen more frequently on mandibular teeth. The purpose of this preliminary study was to determine the prevalence of this lesion among Head Start children. During a dental needs assessment of Mississippi Head Start children, 371 children from 11 centers were examined for this lesion. Of the centers, four were located in optimally fluoridated communities, and six were located in fluoride‐deficient communities. Ages ranged from three to five years. There were 206 males and 165 females, 334 black and 37 white children. At ten centers all children were black, while all children at one center were white. Results indicated no significant differences in the black population between fluoridated (38.2%) and fluoride‐deficient (36.3%) communities (F = .729) or between males (36.8%) and females (37.6%) (P = .877).When data were collapsed on sex and fluoridation status, the racial differences were highly significant(P =.001). The prevalence rate of dental caries associated with primary canine hypoplasia was 26.0 percent. These preliminary data indicate that the presence of primary canine hypoplasia may result in an increased potential for the tooth becoming cari

摘要:

AbstractTooth loss in adults over age 35 usually is attributed t to periodontal diseases. However, certain adult populations are known to have high caries rates. It is not clear to what extent caries contributes to tooth loss in adults. This pilot study examined the causes of tooth loss in a veteran population residing in an 800‐bed, primarily long‐term care facility. The study retrospectively reviewed 572 patients' dental records and documented causes for dental extractions. Of the sample population, 168 teeth were extracted in 51 patients who c had 860 teeth present before treatment. Mean age of the patients undergoing extractions was 57.7 years, lower than the sample population of 60.1 years. Of the 168 teeth extracted, 105 (63%) were attributed to caries and 33 (20%) were documented as root tips, suggesting the presence of root caries. Fifty‐five (33%) were extracted due to periodontal disease and six (4%) were extracted for prosthodontic reasons. Of the maxillary teeth, 67 percent were extracted for caries and 25 percent of periodontal reasons. Caries accounted for 57 percent and periodontal disease accounted for 42 percent of the mandibular teeth extracted. The order in which teeth were most frequently extracted was maxillary anteriors, mandibular anteriors, maxillary and a mandibular premolars, and maxillary and mandibular molars. This study supports the recent work of authors who have found caries contributing significantly to tooth loss in adult popula

摘要:

AbstractWe studied oral hygiene instruction given to 109 patients in 19 Washington State dental practices to investigate the extent to which therapists targeted their efforts toward patients with high disease risk. Patients were examined prior to instruction and prophylaxes. Therapists' instructions were tape‐recorded and their content analyzed: therapists' expectations were scored. There were no statistically significant associations between patients' initial plaque levels and the process/content of the oral hygiene instructions delivered. On average, therapists spent 9.4 minutes of each prophylaxis session discussing oral hygiene. Therapists were judged more genuine with those patients for whom they had higher expectations of compliance, i.e., those with less plaque and low disease risk. We conclude that dental practitioners were not employing effective risk assessment strategies in selection of patients most in need of intensive instructional effort

摘要:

AbstractWe studied the clinical effectiveness of oral hygiene instruction given to 71 “high” plaque patients in 19 Washington State dental practices to determine the extent of plaque reduction. Patients were examined prior to instruction and prophylaxis. Therapist instructions were tape‐recorded and content analyzed, and therapists' expectations were scored. Patients were surveyed as to oral health behaviors and general health habit characteristics. Only 20 of 71 (28%) initially “high” plaque patients had reduced mean plaque scores to 1.0 or less at six weeks. An additional 13 percent had deteriorated plaque levels at 24 weeks. We concluded that therapists did not consistently follow principles of effective instruction and often overestimated their effectiveness. Determinants of relapse involve the educational process, the patients' oral status, and patients' life s
