Studies on cross-contamination in the dental clinic.

The purpose of this study was to determine the amount of cross-contamination of potential pathogens currently occurring in the dental hygiene clinic at the Ohio State University. Results of this investigation show that there is a significant amount of cross-contamination in the clinic. Potentially pathogenic organisms were transferred from the patients' mouths to the fingers of the dental hygiene students, and then to the switches on the dental chair unit and to the handles of the sink. Use of 5% iodophor in 70% isopropyl alcohol was effective in sterilizing certain fomes in the dental operatory.

The atraumatic restorative treatment (ART) approach to restoring primary teeth in a standard dental clinic.

OBJECTIVES: The aims of this study are to assess the feasibility of the Atraumatic Restorative Treatment (ART) approach in primary teeth and to compare the ART approach with traditional amalgam restorations in primary molars. METHODS: This study was conducted in a paediatric dentistry clinic in Kuwait between April 1999 and December 2001. The ART and amalgam restorations were placed randomly on comparable pairs of primary molars, if available. In addition, the ART approach was used for other primary teeth that had no pulpal involvement and no perceived pain before treatment. The restorations were assessed by both the ART evaluation criteria and USPHS criteria in August-September 2000 and in August-December 2001. The mean follow-up period for the restorations was 8.3 months in the first assessment (2000) and 22 months in the second assessment (2001). The assessment was possible for 35 children (mean age = 5.7 years), 18 of whom had comparable pairs (n = 35 pairs) of restorations in their primary molars. In addition, 48 other ART restorations were assessed in 2000 and 42 in 2001. RESULTS: In a 2-year follow-up, 89.6% of all ART restorations were considered successful. The failure rate of the comparable pairs of ART and amalgam restorations was 5.7%. There was no significant difference in success rate between ART and amalgam techniques. CONCLUSIONS: Based on a 2-year follow-up evaluation, the class I ART restorations seemed to have a high success rate, indicating the appropriateness of the ART approach in primary teeth.

Changes in comprehensive dental care of the primary dentition from 1979 to 1989. II. Restorative treatment of primary molars in a population treated at a university dental clinic.

The aim of this study was to compare the success of operative caries therapy of primary molars in two cohorts, one of children born in 1971, Cohort '71, and the other of children born in 1981, Cohort '81, followed up from the age of 3 to 8 years. There were significantly fewer caries lesions to treat in Cohort '81 than in Cohort '71. In Cohort '71, silver amalgam was used while in Cohort '81 silver amalgam was inserted in 65% and glass polyalkeonate cement (GPA) in 35%. Significantly fewer restorations were replaced in Cohort '81 than in Cohort 71, 49 v. 106. When the proportion of replacements was studied in relation to the number of proximal caries lesions, the percentage of replacements in Cohort '71 was 17% and in Cohort '81 14%, the distal surface of the lower first molar showing the same proportion in both cohorts, 21%. Of all replacements in Cohort '81, 41% were performed in the high caries prevalence group. In Cohort '81, 22% of all silver amalgam and 6% of all GPA fillings were replaced. The number of extracted primary molars decreased significantly, from 4% in Cohort '71 to 2% in Cohort '81. The success rate of the operative caries therapy did not increase much. Instead, cost benefits were found in decreasing caries prevalence and later onset of manifest caries.
