Oral Health: Oral hygiene
Intervention
A randomised controlled trial with two study groups:
1. Group 1: standard intervention (control) including manual toothbrush and standardised oral and written tooth brushing instruction based on the bass technique
2. Group 2: as with standard intervention with the addition of standardised photographic evidence of the subjects oral health status and instructions how best to use this.
All paperwork to be used by subjects reviewed by focus group through PPI for B&D service.
Procedure:
1. Define whether patient fits inclusion criteria
2. Gain written photographic consent for inclusion in trial
3. Assign to group 1 or 2 in random fashion
4. Initial appointment: initial questionnaire (demographic data, i.e. age, sex, is appearance important to you, etc.); measure modified plaque and bleeding indices (how much tartar and bleeding from teeth and gums). If assigned to group 2 take initial standard set of photos and give set plus instructions (to put them on bathroom mirror) to subject. If group 1 a single photograph of anterior view showing incisors, to both groups give written oral hygiene instructions.
5. Review at 6 weeks - measure plaque and bleeding indices and take new set of photos appropriate to group, and if group 2 give set to patient
6. Review at 12 weeks - measure plaque and bleeding indices and take final photos and give final questionnaire (how did they use the information given, what was most helpful)
Analysis:
1. For each subject analyse any changes in plaque and bleeding scores and for group 2 compare the standardised initial and review photos for both groups by measuring the change in gingival height from a fixed point on the lower central incisors (i.e., has there been any reduction in swelling to the gums) to give an accurate measure of actional improvements (rather than the kids just brushing hard before coming to the clinic) in oral hygiene. This latter measure will give significance to the results.
2. Maintain record of photographic costs and find information for similar volumes using alternatives, e.g. digital photography, i.e. is it financially viable to use photos for this purpose in clinics.
