The effectiveness of school dental screening: dental attendance and treatment of those screened positive.

OBJECTIVE: To determine dental attendance and treatment outcomes following two models of dental screening. DESIGN: An observational prospective cohort study. SETTING: Infant, primary and junior schools in the North West of England. SUBJECTS: Children aged six to nine years at the start of the study. INTERVENTIONS: Subjects received a screening examination according to either a 'Traditional model' or 'New model' of school dental screening. MAIN OUTCOME MEASURES: Attendance at a dentist within four months of the intervention and treatment received by children referred via the 'New model' with caries in their permanent teeth. RESULTS: In the 'New model' of school dental screening 46% of screened positive and 41% of screened negative children attended a dentist during the study period. Some 44% of children referred with caries in permanent teeth attended a dentist and 53% of those attending received treatment for the referred condition. Larger proportions of children from disadvantaged backgrounds were screened positive but higher proportions of children from more affluent backgrounds attended the dentist and subsequently received treatment. CONCLUSION: School dental screening has a minimal impact on dental attendance and only a small proportion of screened positive children receive appropriate treatment. The programme fails to reduce inequalities in utilisation of dental services.

The development of a consensus among primary care dentists of referral criteria for school dental screening.

OBJECTIVE: To obtain consensus amongst a sample of primary care dentists in the North West of England on a set of clinical criteria that should trigger referral following school dental screening. DESIGN: Delphi process. SETTING: Primary dental care, England 2002. METHOD: Primary care dentists in the North West of England were randomly selected to complete a two round 'Delphi exercise' that included 10 potential referral criteria. The dentists were invited to express their level of support for the inclusion of each referral criterion. MAIN OUTCOME MEASURES: Level of agreement for each referral criterion. Acceptance of any criterion was that the interquartile range should be no more than 3 scale points with the lower value being no less than 7. RESULTS: Eighty-eight dentists, (72.7%), completed the Delphi exercise. Six referral criteria met with the groups' approval: Child with caries in permanent dentition. Child with darkened/discoloured permanent incisors. Child aged 9-10 years with overjet greater than 10 mm. Child over six years with either gross plaque, calculus or swollen gums. Child with evidence of sepsis. Child registered with a GDP with caries in permanent dentition. CONCLUSION: It is possible for a representative sample of primary care dentists in the North West to agree referral criteria following school dental screening.
