- Turesky Modification of the Quigley Hein Plaque Index (TQPHI)<br>
Dental Plaque and debris will be graded using the same scale as the Turesky Index, but at the following six (6) sites: <br>
Mesial, distal and mid surfaces on the facial aspect; Mesial, distal and mid surfaces on the lingual aspect.<br>
The area to be graded on the mesial and distal will be determined by three reference points. These points are the line angle of the tooth to the contact point both bordered by the gingival margin. This allows a small triangular area to be graded. In the event that there is no contact between teeth, the height of contour of the tooth should be used as the reference point.<br><br>
SCORE CRITERIA:<br>
0 = No plaque / debris.<br>
1 = Separate flecks of plaque at the cervical margin of the tooth<br>
2 = A thin continuous band of plaque (up to 1mm) at the cervical margin of the tooth<br>
3 = A band of plaque wider than 1mm but covering less than 1/3 of the
crown of the tooth.<br>
4 = Plaque covering at least 1/3 but less than 2/3 of the crown of the tooth<br>
5 = Plaque covering 2/3 or more of the crown of the tooth<br>
Achtergrond van het onderzoek
The aim of the present study was to evaluate the effect of 3 new developed brush heads compared to a EB17 brush head in relation to gingival abrasion and plaque removing efficacy
Doel van het onderzoek
The 3 new developed prototype electric brush heads (A,B,C) remove 15% more plaque compared to a EB17 brush head
Onderzoeksopzet
- Appointment 1: screening for inclusion, give written consent, instruction not to brush teeth for 48 hours.
- Appointment 2: Measurements and brushing with all 4 brush heads will be used by each subject, one brush per quadrant.
Onderzoeksproduct en/of interventie
- Removing plaque with the 4 different brushheads of an electric toothbrush
- To evaluate the efficacy of new brushheads an investigation will be carried out using a randomized single used cross-over model whereby all brushes will be used by each subject, one brush per quadrant.
- Different brushheads:
1: Prototype EB-A
2: Prototype EB-B
3: Prototype EB-C
4: EB17
