Early Childhood Caries Prevention at a Pediatric Clinic
A study testing fluoride varnish and patient education in people with Dental Caries, run by University of Maryland, Baltimore at 1 site in United States.
Trial summary
This purpose of this study was to evaluate effectiveness of a risk-based dental caries prevention program conducted by dental personnel at an urban pediatric primary care clinic serving largely low-income residents of Baltimore, Maryland, and to appraise this program as a model for similar urban pediatric settings.

About this study
This purpose of this study was to evaluate effectiveness of a risk-based dental caries prevention program conducted by dental personnel at an urban pediatric primary care clinic serving largely low-income residents of Baltimore, Maryland, and to appraise this program as a model for similar urban pediatric settings.
Read the detailed description
A demonstration caries prevention trial lasting 26 months was conducted with a total of 219 children aged 6 to 27 months of age. The "prevention" group consisting of children 6-15 months of age at their initial visit were compared at the end of the trial with a "comparison" group at their initial visit. The comparison group was 12 months older than the enrollment age of the prevention group (18-27 months) and had not received previous routine professional dental care. Interventions were dental examination and periodic recalls, caries-risk assessments, monitoring of oral mutans streptococci (MS) levels, application of 5.0% sodium fluoride varnish to teeth, dental health counseling to care-givers, referral for dental treatment if indicated and periodic recalls.
Outcome measures were: 1) number of decayed, missing, filled primary tooth surfaces, 2) number of pre-carious lesions, 3) counts of oral MS and 3) care-giver responses to a questionnaire about the child's diet and home care.
Prevention group children at the last recall experienced fewer mean carious dental surfaces (0.1 vs. 1.29, p<0.014) and over 8-fold less MS (p<0.013) than comparison group subjects at the initial visit. The number of precarious lesions, however, were not significantly different. In the absence of carious or precarious lesions, oral levels of MS was a reliable indicator of caries risk status, particularly for low risk subjects (sensitivity, 0.64; specificity, 0.98). Caregiver reports of dietary practices and presence or absence of visible dental plaque also served as caries-risk determinants.

Questions about this trial
What is this clinical trial studying?
A study testing fluoride varnish and patient education in people with Dental Caries, run by University of Maryland, Baltimore at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
dmfs scores (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00497029, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 May 2023.
