“…This is surprising as the lower first molar is reported to have the greatest rate of bond failure in the clinical situation. 14,15,16,17 The reason for the higher rate of bond failure for these teeth may be due to greater masticatory forces. 16 If the stresses placed upon ortho- .…”

“…[15][16][17][18][19]21,[23][24][25][26][27] This finding has been attributed to higher masticatory forces exerted on posterior teeth, 19,23,28,29 access difficulties during bonding, [15][16][17]19,25,26 and differences in the micromorphology and structure of the superficial enamel layer between posterior and anterior teeth. 19,23,30 Because more failures were found in boys than in girls (P ϭ .040), it seems that the boys who participated in this study were less attentive to diet and care of the fixed appliances during the observation period.…”

Objective: To comparatively assess clinical failure rate of brackets cured with two different photopolymerization sources after nine months of orthodontic treatment. Materials and Methods: The sample of this study comprised 30 patients who received comprehensive orthodontic treatment by means of fixed appliances. Using the same adhesive, 600 stainless steel brackets were directly bonded and light cured for 10 seconds with the light-emitting diode (LED) lamp or for 20 seconds with the conventional halogen lamp. A split-mouth design randomly alternated from patient to patient was applied. Failure rates were recorded for nine months and analyzed with Pearson 2 test, and log-rank test at ␣ ϭ .05 level of significance. Results: The overall failure rate recorded with the halogen unit (3.33%) was not significantly different from the failure rate for the LED lamp (5.00%). Significantly more failures were found in boys compared with girls, in the mandibular dental arch compared with the maxillary arch, and in posterior segments compared with anterior segments. However, no significant difference was found between the right and left segments. Conclusion: Both light-curing units showed sufficiently low bond failure rates. LED curing units are an advantageous alternative to conventional halogen sources in orthodontics because they enable a reduced chair-time bonding procedure without significantly affecting bond failure rate.

“…As it has been reported in most previous studies, the highest failure rate of orthodontic brackets occurred in the posterior region when compared with the anterior region (16,21,23). The high incidence of bracket failures in the posterior teeth could be associated to a number of factors, such as poor moisture control, (21,23,26) the partial eruption of second premolars (27,28), the heavier occlusal forces exerted on the posterior teeth during mastication (16,29) and the larger amount of aprismatic enamel on premolars affecting the quality of micromechanical bond (21).…”
