conventional acid etching technique with the use of pumice prophylaxis with use of Aster Prophy Pumice Prophylaxis paste, 3M ESPE scotchbondâ„¢ etchant, 3Mâ„¢ Transbondâ„¢ XT Light Cure Adhesive in Syringes kit |
The maxillary right segment teeth will be addressed. Before bonding, the labial/buccal surface of the incisors, canine, and premolars will be cleaned using a fluoride-free, oil-free Aster Prophy Pumice prophylaxis paste. It will then be washed with water and dried with compressed air .The mid-buccal enamel of each tooth will be etched for 15 to
30 seconds with a 37% 3M ESPE scotchbondâ„¢ etchant orthophosphoric acid gel applied by a sponge pledget. After rinsing with distilled abundant water spray and drying with oil-free compressed air to achieve a frosted enamel
appearance, Transbond XT primer will be applied to the etched surface. Transbond XT composite will then be applied to the bracket base, the bracket will be placed firmly in position, and excess composite will be removed prior to light curing about 40 seconds

Brief Summary
Modification(s)

This study aims to
contribute more evidence-based research to the existing orthodontic literature.
The following conclusions can be drawn based on the findings of this clinical
investigation:
1. Conventional
acid etching with pumice prophylaxis (Group A1) exhibited the lowest bond
failure rate (5.0%) over the 9-month observation period and showed
statistically significant superiority (p = 0.015) in long-term bracket
retention compared to other groups, reaffirming its reliability as the gold
standard for bonding.
2. Self-etching
primers (SEP) significantly reduced chairside bonding time due to a simplified
application process. The shortest mean bonding time was observed in Group B2
(115.6 sec), while Group A1 took the longest (156.55 sec). These differences
were highly statistically significant (p < 0.001).
3. Pumice
prophylaxis significantly enhanced bond strength and reduced bond failure rates
in both conventional and SEP systems. The bond failure rate in Group B2 (SEP
without pumice) was 18.0%, which was significantly higher than in Group B1 (SEP
with pumice) at 8.0%, confirming that pumice use significantly improves enamel
preparation (p = 0.035 for B1 vs. B2).
4. Most
bracket failures occurred in the first 6 months, particularly in Group B2
(15.0%), and the chi-square analysis showed statistical significance at this
stage (p = 0.040). This highlights the critical role of precise bonding
technique and patient compliance in the early treatment phase.
5. While
SEP systems offer time efficiency, they may compromise bond
reliability—particularly without pumice. For consistent clinical success,
clinicians should strive for a balance between procedural efficiency and
long-term bond stability, using pumice prophylaxis with SEP when necessary, and
maintaining traditional CAE with pumice as the most dependable bonding
protocol. |
