The Use of Pit and Fissure Sealants in Children Requiring Caries Related Dental Extractions

Dental Caries Clinical Trial

Official title: A Pilot Study to Investigate the Use of Pit and Fissure Sealants in Children Requiring Caries Related Dental Extractions Under a Chair General Anaesthetic

Status Completed

Clinical Trial Summary

The purpose of thus study is to assess the feasibility and inform the planning of a proposed definitive randomised controlled clinical trial to investigate the efficacy of sealing permanent molars in children requiring caries related extractions under a chair General Anaesthetic.

Clinical Trial Description

Objective:

To evaluate,

1. The ability to recruit based on failure to meet exclusion criteria, declining to participate or other reasons and retention rates based on subsequent withdrawals.

2. Feasibility and acceptability of placing sealants in this setting, based on compliance with the intervention.

3. Sealant retention rates based on the proportion of sealants that were fully intact, partially intact or lost after 24 months.

4. Two-year incidence of caries in permanent molars that were sound and suitable for sealants at the time of the pre-GA assessment, based on the proportion of children with:

1. Experience of caries into dentine in at least one permanent molar

2. Untreated caries into dentine in at least one permanent molar

5. Oral health related Quality of Life (OHRQoL) two years following caries related extractions under GA, based on the Child-Oral Impacts on Daily Performances (Child-OIDP) scale and separate questions relating to specified oral symptoms.

6. Oral health support provided by referring practitioners, within the 2 years following the dental GA, based on,

1. Structured interview questionnaire to record parents' experience of preventive advice and treatment received, following the GA extractions

2. Sealants identified at follow up that were not present at baseline or provided as part of the study

Recruitment and randomisation:

Recruitment was carried out over a total period of 8 months. However, during this time, the study investigator (AR) was only available to recruit participants on ad hoc dates. Therefore, to facilitate recruitment, referral letters were triaged to identify children that were likely to be eligible (based on age, postcode and reason for GA referral) so they could be scheduled on these dates.

Study information (including separate leaflets for parents and children) was posted a few weeks before the GA assessment appointment.

At this visit, clinicians responsible for completing the GA assessment, also screened children to identify those that had potentially sealable permanent molars, and they were then invited to see the investigator on the same day. Further to this, eligibility to take part in the study, based on the full list of inclusion criteria was confirmed following full verbal and written consent.

Results:

Although the recruitment period extended over 8 months, as explained earlier, the study investigator was only available to undertake enrolment on a limited number of ad hoc sessions throughout this time. Based on these, 132 children were assessed for eligibility. ;
