Abstract
Aim: The study evaluated enamel surface roughness after bracket debonding and adhesive removal using three methods: Tungsten carbide burs (TCB), aluminum oxide air abrasion (AO), and sodium bicarbonate air abrasion (SB).
Materials and methods: A total of 90 extracted premolars were divided equally into three groups based on adhesive removal methods: TCB, AO, and SB. Procedures were performed under a 4× magnifying loupe. Surface roughness (Ra) was measured using a profilometer and atomic force microscopy (AFM) before bonding (T0). Brackets were bonded, debonded after 24 hours, and the adhesive remnant index (ARI) was assessed. After adhesive removal, Ra was re-evaluated (T1), and removal time was recorded. Data were analyzed using IBM Statistical Package for Social Sciences software.
Results: The results showed no significant difference in ARI among the three groups. All methods led to a significant increase in Ra after adhesive removal (p < 0.001), with the highest Ra in the TCB group, followed by AO, and the lowest in SB. Atomic force microscopy analysis confirmed these findings with surface area roughness (Sa) values. Sodium bicarbonate air abrasion required the shortest adhesive removal time, followed by AO, while TCB took the longest.
Conclusion: Sodium bicarbonate air abrasion effectively removes adhesive remnants and produces the lowest surface roughness compared with other methods. Air abrasion offers a promising alternative to rotary handpieces, restoring the enamel surface to a nearly original condition and reducing the risk of permanent tooth damage.
Clinical significance: Sodium bicarbonate air abrasion is a fast, minimally invasive method for adhesive remnant removal. It preserves enamel integrity.

期刊介绍：
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
