Brief summary
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.
Detailed description
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.
Interventions
PROCEDUREAir Polishing
After ultrasonic scaling, teeth will be polished using sodium bicarbonate air polishing with an air polishing device in a circular motion for 10 seconds.
PROCEDUREUltrasonic Scaling
Teeth in the control group will undergo ultrasonic scaling only, with no additional polishing procedures.
PROCEDUREBristle Brush Polishing
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.
PROCEDURERubber Cup Polishing
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.

Masking description
This study follows a double-blind approach where both the SEM technician capturing micrographs and the analyst evaluating surface roughness will be blinded to the specific group allocations.
Intervention model description
The study compares the effects of three different polishing methods (bristle brush, rubber cup, and air polishing) on tooth surface roughness in a randomized controlled trial with a control group.

Inclusion criteria
* Extracted human teeth with intact buccal or lingual surfaces. * Patients with a history of trauma affecting the oral cavity will be eligible, provided they meet other criteria (e.g., intact buccal or lingual surfaces). * Male and female patients aged 18 years and above.
Exclusion criteria
* Teeth with restorations, caries, fractures, or significant developmental defects (e.g., amelogenesis imperfecta, dentinogenesis imperfecta , fluorosis etc). * Patients with systemic disease such as diabetes mellitus, cardiovascular disorders or any other condition will be excluded. * Mentally impaired patient. * Patients who have undergone scaling and polishing within the last 3 months.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Tooth Surface Roughness | 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. |
