Abstract 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 χ2 test, and log-rank test at α = .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.

The purpose of the present study was to evaluate in vivo the failure rate of metallic brackets bonded with two orthodontic composites. Nineteen patients with ages ranging from 10.5 to 38.7 years needing corrective orthodontic treatment were selected for study. The enamel surfaces from second premolars to second premolars were treated with Transbond Plus-Self Etching Primer (3M Unitek). Next, 380 orthodontic brackets were bonded on maxillary and mandibular teeth, as follows: 190 with Transbond XT composite (3M Unitek) (control) and 190 with Transbond Plus Color Change (3M Unitek) (experimental) in contralateral quadrants. The bonded brackets were light cured for 40 s, and initial alignment archwires were inserted. Bond failure rates were recorded over a six-month period. At the end of the evaluation, six bond failures occurred, three for each composite. Kaplan-Meyer method and log-rank test (Mantel-Cox) was used for statistical analysis, and no statistically significant difference was found between the materials (p=0.999). Both Transbond XT and Transbond Plus Color Change composites had low debonding rates over the study period.

BACKGROUND: Bonding is an important step in fixed orthodontic mechanotherapy. Many new materials introduced an adhesive for bonding. This study was designed to evaluate the clinical bond failure rate of orthodontic brackets bonded with green glue: two way color changes adhesive and transbond XT adhesive paste.METHODS: Eighteen male patients with a mean age of 16 years were included in the study. Convenience sampling technique was used to select the sample for this study. The split-mouth design was used to bond 360 brackets by one operator and both adhesives were used in each patient. Bond failure rates were estimated with respect to bonding procedure, dental arch, tooth type (incisor, canine, and premolar). The results were evaluated using the chisquare test. Kaplan – Meier analysis and the log rank test were used to estimate the survival rate of the brackets. Bracket failure rates for each system were analyzed, and failure causes as reported by the patients and the quadrant of each tooth in which bracketsfailed were recorded.RESULTS: The bond failure rate was 5.00% and 4.44% for green gloo and transbond XT group. No significant difference was found in the bond failure rate between transbond XT and Green gloo group. No significant difference was found in the bond failure rate between the two groups, in relation to right and left side and the type of teeth.CONCLUSION: Green gloo adhesive can be effectively used to bond orthodontic brackets.

One hundred and twelve first molar bands and 614 directly bonded brackets on incisor, canine, and premolar teeth were included in a clinical trail to investigate the importance of omission of pumice prophylaxis at the time of banding and bonding, on their possible subsequent failure. Half of the sample were selected for the non-pumiced test groups using a random number allocation method, the remaining pumiced teeth acting as control groups. Two etch times were used for the direct bonding part of the study, 15 and 60 seconds, with non-pumiced test and pumiced control groups included within both etch-time groups. Results showed no statistical difference in the failure rate of attachments in either test or control groups during the course of treatment. The different etch times had no significant effects in the direct bonding part of the study.

Background: The aim of the study was to compare the survival rate of brackets bonded with amorphous calcium phosphate containing adhesive and fluoride releasing orthodontic adhesive over 6 months period. White spot lesions were also evaluated prior to bonding, 3 months and 6 months from the date of bonding. Methods: Thirty six orthodontic patients were randomly divided into two equal groups using split mouth design. 592 brackets were bonded up to the premolars with either Aegis Ortho or Transbond Colour Change(TPCCA). Bracket failure rate and survival distribution were evaluated and compared using Kaplan- meier analysis and Log rank test with respect to adhesives, dental arches, segments , tooth types, gender and age groups. White spot lesion was assessed using WSL index. Results: There was no significant difference between the failure rate of Aegis Ortho(3.0%) and TPCCA(1.4%). Kaplan Meier analysis, Log rank test showed that the difference in the overall failure rate and survival time between the arches, gender, and different age groups were not statistically significant. Both adhesives had a high bond failure rate in the posterior segment especially in the premolar region. Three patients had white spot lesions in the upper premolar region bonded with Aegis ortho. Conclusion: Both Aegis ortho and Transbond plus colour change adhesive with a low bond failure rate can be used as an alternative orthodontic adhesive. Key words : bond failure, amorphous calcium phosphate, transbond colour change adhesive, white spot lesions.

ABSTRACT INTRODUCTION: The use of flowable composites as an orthodontic bonding adhesive merits great attention because of their adequate bond strength, ease of clinical handling and reduced number of steps in bonding. OBJECTIVE: The aim of this Randomized Controlled Trial was to comparatively evaluate over a 6-month period the bond failure rate of a flowable composite (Heliosit Orthodontic, Ivoclar Vivadent AG, Schaan) and a conventional orthodontic bonding adhesive (Transbond XT, 3M Unitek). METHODS: 53 consecutive patients (23 males and 30 females) who fulfilled the inclusion and exclusion criteria were included in the study. A total of 891 brackets were analyzed, where 444 brackets were bonded using Heliosit Orthodontic and 447 brackets were bonded using Transbond XT. The survival rates of brackets were estimated with the Kaplan-Meier analysis. Bracket survival distributions for bonding adhesives, tooth location and dental arch were compared with the log-rank test. RESULTS: The failure rates of the Transbond XT and the Heliosit Orthodontic groups were 8.1% and 6% respectively. No significant differences in the survival rates were observed between them (p= 0.242). There was no statistically significant difference in the bond failure rates when the clinical performance of the maxillary versus the mandibular arches and the anterior versus the posterior segments were compared. CONCLUSIONS: Both systems had clinically acceptable bond failure rates and are adequate for orthodontic bonding needs.
