The Effect of Disclosing Dental Plaque on Plaque Index and Gingival Index in Faculty of Dentistry Students

Summary

The hypothesis of this study is; using the tooth disclosing agents by individuals has a positive effect on oral care and as if it is an effective method in improving oral health. Therefore, the aim of this study is to assess the effect of visual guidance of plaque disclosing agents on plaque removal efficacy for patients versus the group of patients evaluated without any tools.

Istanbul Medipol University Faculty of Dentistry 4th grade students are going to be invited to the study. The study will carry out with a total of 124 students. The students who are systemically healthy, drug-free, and at least 20 teeth in the mouth will be included in the study. Smokers, those undergoing orthodontic treatment, the presence of pain or infection that may prevent brushing, pregnant/breastfeeding students, and students who do not agree to participate in the study will not include to the study.

After the initial records (Plaque index and Gingival Index and DMFT- caries, missing teeth due to caries, filled teeth) were obtained, the students in the study will randomly divide into 2 groups:

Group 1; Control Group (n=62) After explaining the Modified Bass Technique and the use of dental floss/interface brush, students will be asked to brush their teeth.

Group 2; Test Group (n=62) After explaining the Modified Bass Technique and the use of dental floss/interface brush, the teeth will stain with a plaque disclosing agent, the plaque is going to be shown in the mirror and then the students will brush their teeth.

Post-operatively, periodontal parameters will be evaluated. Plaque index and gingival index will be measured immediately after brushing, 1 week, 1 months are going to be compared to baseline. A single investigator will make measurements of Gingival Index (GI, Löe and Sillness-1967) and Plaque Index (PI, Sillness and Löe-1964) using a Williams periodontal probe. Measurements will be obtained from 4 surfaces of all teeth (mesiobuccal, midbuccal, distobuccal, midlingual) except third molar teeth, and the values obtained will be summed and averaged, and the average of one tooth. Then, these values will be summed up and averaged, and the mean PI and GI of the individual will be obtained. The outcomes of the two groups will be evaluated by statistical analysis.

Conditions

• Periodontal Indexes
• Oral Health

Interventions

OTHER

Experimental: Group 1 (dental examination-training-tooth brushing) Experimental: Group 2 (dental examination-training-plaque disclosing-tooth brushing)

All participants will be examined and their decay, filling and extracted teeth, plaque index and gingival index measurements will be recorded. Plaque disclosing will be applied to Group 2 after brushing training.
