Brief Summary
Micro-CT is a non-destructive imaging method with high resolution and allows to examine all tooth structures individually. Pre- and post-application images obtained by micro-CT can be superimposed and differences can be precisely detected. Intraoral scanners in CAD/CAM systems also provide non-destructive image scanning. CAD/CAM are systems that are widely used in dentistry today. Access to the device is easier than micro-CT. This study was focused on to compare two different imaging methods by assessing changes caused by sodium bicarbonate and glycine air polishing on the tooth surfaces.

Outcome Measures
Primary Outcomes (1)
Defect volume
The teeth were divided into two groups, the crown and exposed root surface were air polished using glycine and sodium bicarbonate powders at instrumentation time of 5s, combinations of medium and maximum power and medium water settings, distance of 5mm and angulation of 60 degree. Samples were scanned in a micro-computed tomography (micro-CT) and CAD/CAM at baseline and then after powder treatment and the defect volume was estimated.
5 second
Study Arms (2)
Micro-CT
Samples were scanned before and after air polishing with a high-resolution micro-CT device. The scanning conditions were 100 kVp; 100-mA, 0.5-mm Al/Cu filter; 13.1-μm pixel size; and rotation at 0.2 steps. According to the manufacturer's instructions, each sample was rotated 360°. The mean scanning time was around 1hour.
CAD/CAM
The teeth surfaces were digitalized before and after air polishing with an intraoral scanner. The mean scanning time was around 10 second. The virtual images of the scanned teeth were saved in stereolithography (STL) format.
Interventions
Micro computed tomography (micro-CT) is an imaging method in which cross-sectional images are obtained and these images are transferred to the computer through specific software, processed and stored.
CAD/CAM (computer aided design-computer aided manufacturing) is a production method that is frequently used in many areas of technology. These systems are composed of a data acquisition unit, software for designing virtual restoration, and a computerized milling device.
Eligibility Criteria
The patients were recruited from individuals seeking periodontal and/or dental treatment at Kocaeli University, Faculty of Dentistry.
You may qualify if:
- Being older than age of 18, Willing to participate the study, To have a single rooted tooth with gingival recession on all surfaces and need to be extracted, The tooth has to be free of caries, defects and restorations.
You may not qualify if:
- Have history of infectious diseases like Hepatitis and/or HIV (+).
