A bibliometric analysis of the pediatric dental literature in MEDLINE.

PURPOSE: The purpose of this study was to estimate the availability of dental literature between 1989 and 1998 in seven disciplines within pediatric dentistry by using a bibliometric analysis on MEDLINE and to compare the results to that for adolescents and adults. METHODS: A search strategy was developed for each discipline incorporating dental vocabulary obtained from the MEDLINE Medical Subject Heading (MeSH) index. The number of articles retrieved from MEDLINE for adolescents and adults (> 13 yo) was compared to those for children (< 12 yo) in seven dental disciplines: dental implants, endodontics, oral medicine/radiology, oral surgery, orthodontics, periodontics, and restorative dentistry. RESULTS: There was an average of 8,097 dental articles published each year for the combined seven disciplines studied with an eight-fold range from 327 articles/year for endodontics to 2,765 articles/year for oral medicine/radiology. Of the mean number of articles published each year, 1,273 (16%) were limited to children, while the remaining 6,824 (84%) were on adolescents and adults. The number and percentage of children articles relative to the total number of publications on children ranged from 7 articles/year (1%) for dental implants to 528 articles/year (42%) for oral medicine/radiology. Implant dentistry publications increased the fastest, growing at an average yearly rate of 25%, followed by restorative dentistry (9%), endodontics (9%), oral surgery (6%), orthodontics (6%), periodontics (3%), and oral medicine/radiology (2%). CONCLUSIONS: There is a substantial amount of literature in pediatric dentistry upon which to base clinical decisions. Within this large body of literature, there is a significant amount of variation between the various dental disciplines examined. To stay current, one would need to read and absorb approximately 24 articles each week over 52 weeks per year in more than 75 different journals. Furthermore, the volume of literature is increasing each year, making access even more difficult. These trends suggest the need for computer systems that will facilitate access and retrieval of clinically useful literature.

Children with hypoplastic enamel defects of primary incisors are not at increased risk of learning-problem syndromes.

Developmental enamel defects of primary teeth have been associated in earlier reports with motor, hearing and psychological disturbances. The relationship between hypoplastic enamel defects and learning problems had not been evaluated previously. For a total of 149 girls and 196 boys we collected a primary tooth shortly after shedding and approximately 2 years later a teacher-completed questionnaire about function in school. Children with a hypoplastic enamel defect of one of their primary incisors were no more likely than their peers without an enamel defect to have any of 7 different learning problem syndromes. In the absence of reason to suspect selection bias, confounding, or misclassification of hypoplastic defects or school problems, we conclude that hypoplastic enamel defects are not associated with teacher-identified learning problems.

Investigation of the possible associations between fluorosis, fluoride exposure, and childhood behavior problems.

PURPOSE: This study investigated the potential association between fluoride exposure and behavior problems in children, as well as the prevalence of and risk factors for fluorosis. METHODS: Children between the ages of 7 and 1 years (N = 197) were included in the study and were examined for dental fluorosis using the Modified Dean's Index. Parents of subjects completed and returned three questionnaires which investigated their children's history of exposures to fluoride, social and medical backgrounds, and behavior using the Child Behavior Checklist (CBCL). RESULTS: Sixty-nine percent of the study participants demonstrated fluorosis with very mild fluorosis being the most common (39%), while 13% demonstrated moderate to severe fluorosis. Using a summation of the Modified Dean's index (Sum of 8), we divided the children into high fluorosis (HF) and low fluorosis (LF) groups. These groups were compared to each other with respect to fluoride exposures and behavior. CONCLUSION: Although there was no association between the fluoride exposures in aggregate and fluorosis, there was a significant association between supplemental fluoride exposure from ages 0-3 years and fluorosis. There was no association between behavior problems and dental fluorosis in this population.
