简要总结

This study investigates the effects of three polishing methods using a bristle brush, rubber cup, and air polishing on the surface roughness of scaled human teeth. The study aims to determine which polishing method is most effective in minimizing roughness and preventing plaque accumulation, thus contributing to improved oral health practices.

详细描述

Tooth surface roughness influences plaque retention and periodontal health. Polishing after scaling helps smoothen enamel surfaces, reducing bacterial adhesion. While various studies have assessed polishing techniques, there are inconsistencies in findings, particularly regarding air polishing vs. rubber cup polishing. Additionally, most studies focus on bovine teeth or indirect restorative materials rather than extracted human teeth. Using a randomized controlled trial (RCT) design, 56 extracted teeth will be divided into four groups: a control group (no polishing) and three experimental groups subjected to different polishing techniques. Surface roughness will be analyzed using a Scanning Electron Microscope (SEM). This study aims to fill these research gaps and provide region-specific data by determining which polishing method is most effective in minimizing roughness and preventing plaque accumulation, thus contributing to improved oral health practices.

研究组 & 干预措施

Bristle Brush Polishing Group

Experimental

After ultrasonic scaling, teeth will be polished using a bristle brush attached to a low-speed contra-angle handpiece with prophylaxis paste in a circular motion for 10 seconds.

干预措施: Bristle Brush Polishing (Procedure)

Rubber Cup Polishing Group

Experimental

After ultrasonic scaling, teeth will be polished using a rubber cup attached to a low-speed contra-angle handpiece with prophylaxis paste in a circular motion for 10 seconds.

干预措施: Rubber Cup Polishing (Procedure)

Air Polishing Group

Experimental

After ultrasonic scaling, teeth will be polished using sodium bicarbonate air polishing with an air polishing device in a circular motion for 10 seconds.

干预措施: Air Polishing (Procedure)

Control Group

Active Comparator

Teeth in this group will undergo ultrasonic scaling only, with no additional polishing procedures.

干预措施: Ultrasonic Scaling (Procedure)

结局指标

主要结局

Tooth Surface Roughness

时间窗: Immediately after intervention (post-polishing SEM analysis).

The arithmetic mean roughness (Ra) and root mean square roughness (Rq) of the enamel surface will be measured using Scanning Electron Microscopy (SEM) analysis and ImageJ software. This will assess the effectiveness of different polishing techniques in reducing surface roughness after ultrasonic scaling.
