Effectiveness of an antibacterial primer used with adhesive-coated brackets on enamel demineralization around brackets: an in vivo study

Abstract

Background The aim of the study is to assess the clinical effect of an antibacterial monomer-containing primer on preventing white spot lesions (WSLs) during fixed orthodontic treatment. Subject and methods The study included 35 patients. A split-mouth design was used during bonding of the brackets. In Clearfil (CF) group, adhesive-coated brackets (APC Plus Victory series, 3M Unitek, Monrovia, CA, USA) were bonded with an antibacterial monomer-containing primer (Clearfil Protect Bond, Kuraray Medical, Okayama, Japan). In Transbond (TB) group, the same adhesive-coated brackets were bonded using a conventional primer (Transbond XT Primer; 3M Unitek, Monrovia, CA, USA). The mean duration of orthodontic treatment was 16 months. Digital images of each tooth were used to assess the WSLs. The areas of the WSLs were measured with a software. The bond failures during orthodontic treatment were also recorded. Results After fixed orthodontic treatment, 23 of the 35 patients showed one or more WSLs. Of the total of 666 teeth, 114 WSLs occurred over the orthodontic treatment time. Rates of WSL in the CF and TB groups were 8.03% and 9.24%, respectively. The difference in WSL rates between the two groups was not statistically significant. No significant difference was observed in the lesion areas between the groups. Moreover, the difference in bracket failure rates between the two groups was also not statistically significant. Conclusion The results of this long-term clinical study indicated no significant difference between the antibacterial monomer-containing primer group and the control group in the efficacy of reducing demineralization throughout the orthodontic treatment.

White Spots: Prevention in Orthodontics—Systematic Review of the Literature

“…The considerable drop in salivary pH and rise in plaque index may be one cause of the rise in DMFT index. Because increased salivary flow is associated with a rise of the plaque index, which reduces pH, it does not seem to be good to reduce the possibility of carious lesion occurrence [ 28 , 39 ].…”

“…The aim of the study by Oz et al, is to clinically evaluate an antibacterial primer containing monomer in the prophylaxis of WS during fixed therapy [ 28 ]. The study’s findings demonstrate that there was no discernible difference between the antibacterial monomer-containing primer group and the control group in terms of their capacity to prevent demineralization during orthodontic treatment [ 68 ].…”

An In Vitro Comparison of Clinpro™ XT and Duraphat Varnish for Protecting Teeth from Discoloration during Orthodontic Treatment

“…Tus, it inhibits the demineralization of the enamel surface [29]. Te layer formed by fuoride varnish on the enamel surface can even act as a shield, reducing the adsorption of cofee [30].…”

Effectiveness of a Selective Etching Technique in Reducing White Spots Formation around Lingual Brackets: A Prospective Cohort Clinical Study

“…This could also explain why dental plaque accumulation was lower in test sides compared to control sides, without any increase during the entire first year of treatment in test sides, where all the enamel surface sandblasted and etched was covered by the bracket base and sealed with a resin cement. Furthermore, the utilization of a self-adhesive resin cement allowed for avoiding the application of a bonding agent known to contain chemical components with an estrogenic effect that, if some adhesive remnants remain below the gingival margin, promote increased inflammation, gingival swelling, and, consequently, an increase in plaque accumulation [31,32].…”
