“…Transbond XT adhesive, a composite resin, was chosen as one of the controls due to its popularity and common use in other bond strength studies. 7,8 Similar to the claims made by the ACP-adhesive manufacturer, the use of resin-modified glass ionomer cement (Fuji Ortho LC) has been said to be more effective in preventing white spot lesions than conventional composite resins. 9 Using this cement as another comparative group allows comparison of adhesives marketed for the purpose of white spot prevention.…”

“…A storage time of 40 hours was chosen since short times in excess of 24 hours are not critical 10 and also to remain consistent with previous studies using Transbond XT as a control. 8,11 An Instron universal testing machine (Instron Corp, Canton, Mass) was used to debond the brackets using a shear load applied to the bracket at a crosshead speed of 0.1 mm/min. Specimens were positioned in the Instron machine in a manner such that the loading force was directed parallel to the long axis of the tooth and contact was made as close to the bracket/tooth interface as possible.…”

Objective: To determine whether an amorphous calcium phosphate (ACP)-containing adhesive has an acceptable level of shear bond strength to be used as an orthodontic adhesive. Materials and Methods: Sixty extracted premolars were randomly divided into three groups for orthodontic bonding. Group 1 used a composite resin adhesive (Transbond XT), group 2 was bonded with an ACP-containing adhesive (Aegis Ortho), and group 3 used a resin-modified glass ionomer (Fuji Ortho LC). All bonded teeth were stored in distilled water at 37ЊC for 40 Ϯ 2 hours prior to debonding. Shear bond strength and adhesive remnant index (ARI) were recorded for each specimen. Results: The mean shear bond strengths for the three test groups were: group 1 (15.2 Ϯ 3.6 MPa), group 2 (6.6 Ϯ 1.5 MPa), and group 3 (8.3 Ϯ 2.8 MPa). A one-way analysis of variance showed a significant difference in bond strengths between the groups. A post hoc Tukey test showed group 1 to be significantly (P Ͻ .001) greater than groups 2 and 3. A Kruskal-Wallis test and a Mann-Whitney U-test showed groups 1 and 3 exhibited lower ARI scores than group 2, but a majority of specimens in each group had greater than 50% of the cement removed along with the bracket during debonding. Conclusions:The ACP-containing adhesive demonstrated a low, but satisfactory bond strength needed to function as an orthodontic adhesive.

“…Vicente et al suggested use of TPCCA along with TSEP/TMIP if there is a risk of contamination with water or saliva. Northrup et al 20 have reported clinically acceptable SBS of a similar color changing adhesive 'bluegloo' (Ormco Corp) with self-ligating bracket in comparison with Transbond XT bonded to self-ligating bracket and conventional stainless steel bracket. Bluegloo also posses the property of color change with temperature retaining blue color in cooler temperature and changes to tooth color with activation by light.…”

Objective: To determine the efficiency of Transbond plus color change adhesive (TPCCA), a newly introduced orthodontic adhesive material with reference to shear bond strength (SBS), debonding characters and degree of cure (DC) and to correlate SBS to the DC. Materials and methods:Forty human premolars, divided into Group I (n = 20) Transbond XT and Group II (n = 20) TPCCA were bonded with metal brackets using the adhesives. Brackets were debonded in shear on an Instron universal testing machine with a crosshead speed of 1 mm per minute. The mode of bond failure was determined by Modified ARI index and the DC was determined by FTIR analysis.Results: There was no statistically significant (p > 0.05) difference between SBS of TPCCA [SD-8.87 (2.11)] and conventional Transbond XT [SD-10.54 (3.12)] and therefore was clinically acceptable. The Weibull analysis suggested that TPCCA behaved consistently with respect to bond failure and reliability. Both adhesives exhibited cohesive type of bond failure. A statitistically significant lower percentage of DC was noted for TPCCA [65.9 (2.4)] than Transbond XT [68.7 (3.2)] but it was within the range reported in the literature (55-75%).Pearson's correlation was significantly positive between SBS and DC for both adhesives. Conclusion:TPCCA has optimum SBS, favorable debonding character and DC at clinically acceptable levels.Clinical implication: TPCCA can be a considered as an innovative orthodontic adhesive material for clinical use.

“…This type of bond failure was preferable because less risk of enamel damage during debonding. 9 It was recommended to have a resin remnant on the tooth surface after debonding to prevent enamel crazing or fracturing. 10 Furthermore, the results of dental disclosing solution application in ARI were consistent with intra-operator and inter-operator reliability of photograph assessment.…”
