“…In the medium viscosity IDBS without the adhesion promoter, the SBSs for two (11.8%) of 17 specimens were less than 6MPa, and the mean SBS reached 6 MPa. These results are consistent with the findings of Goto et al 11) that the SBSs for two (8.7%) to three (13.0%) specimens out of 23 were less than 6 MPa in the BOB Paste Viscos DBS. To obtain a clinically adequate level of SBS in the medium viscosity IDBS, this system needs to be used in combination with an adhesion promoter.…”

“…Some studies have reported that an adhesion promoter significantly increased the SBS in IDBSs 7) and DBSs 8) , whereas others have reported that this promoter did not significantly increase the SBS in a DBS 9) . Some DBS studies have shown that the SBSs achieved with high-viscosity adhesives with a high amount of filler were significantly higher than those obtained with low-viscosity adhesives with a small amount of filler 10,11) . However, other studies found no significant differences among the SBSs achieved with adhesives of different viscosities 12) .…”

“…Still, there is no optimum or ideal bonding force mentioned in literature other than advocating the application of gentle force [3] to get the uniform thickness of adhesive. However, few researchers in past have studied the effect of bonding force which widely varied from 50 g to 1000 g. Goto et al [4] reported that increasing the contact compressive force caused a significant reduction in adhesive thickness and shear bond strength. However, Jain et al [5] in 2013 noted that an increase in bonding force tends to increase shear bond strength initially to a specific thickness and later on it decreases with a decrease in film thickness.…”

“…It is important to note that the previous studies [4][5][6][7][8][9] have used indirect methods to apply compressive bonding force while seating bracket on the tooth surface. Hence, the results of these studies have to be considered with caution; as there was no specialized orthodontic instrument used in the past that can measure bonding force directly and accurately while positioning a bracket on tooth surface.…”

Objectives: The optimum adhesive thickness present between bracket base and tooth surface plays an important role in achieving ideal treatment outcome in straight wire technique. As thickness of adhesive largely depends on amount of force applied while bonding an orthodontic brackets on the tooth surface. Therefore, it becomes prudent to find direct and accurate method to quantify the bonding force. The aim of this paper was to describe the design and working of novel bracket positioning gauge with force sensor which directly quantifies the amount of bonding force applied by orthodontists. Material and Methods: The present prototype is a bracket positioning gauge where load cell and vertical stopper blade are fixed on base platform. The force sensing blade attached to load cell detects the force applied and transmit to load cell which converts compressive force into an analogue signals. These inputs are then converted into digital signals for further processing. The prototype was tested five times by ten orthodontists for measuring bonding force while orthodontic brackets were bonded on extracted premolars. The same procedure was repeated after seven days to assess the reproducibility and reliability of prototype. Results: The majority of orthodontists participated in present study applied bonding force between the ranges of 50-200 grams with the mean bonding force applied by participant orthodontists was similar in time interval of seven days with 134.67 grams and 132.76 grams respectively. Conclusion: The novel bracket positioning gauge with force sensor was able to measure compressive bonding force accurately and can aid in achieving optimum adhesive thickness for clinically acceptable bond strength. The present innovation needs further refinements to be more useful in clinical settings.

“…To avoid any examination bias, the photographs were coded by a person who was unrelated to this research. These coded photographs were examined by an investigator to evaluate the bond failure modes using the adhesive remnant index (ARI) 12) . One month later, the same examiner made a second evaluation of the ARI scores.…”

The purpose of this study was to determine whether a system using a resin coating material (PRG Barrier Coat) with anticariogenic ability can effectively bond orthodontic brackets to human teeth. Resin-modified glass-ionomer cement system (Fuji Ortho LC, group 1) and resin composite cement systems (BeautyOrtho Bond) combined with a self-etching primer (group 2), with the resin coating material (group 3), and with the resin coating material after an organic acid etching agent (group 4) were used for bracket bonding. The mean shear bond strength (SBS) was significantly higher in group 1 than in groups 2, 3 and 4. Groups 2 and 4 exhibited a significantly higher mean SBS than group 3. The resin composite cement system combined with the resin coating material after the organic acid etching agent can serve as an alternative for orthodontic bracket bonding.
