ABSTRACT

Orthodontic bonding adhesive is one of the integral parts of orthodontic treatment. By means of orthodontic bonding adhesives, different components of fixed orthodontic appliances are attached to the tooth surface. Manufacturers have been introducing various bonding adhesives as there is an increasing demand for orthodontic treatment presently. Focus has been made more on the physical properties of these bonding adhesives rather than their biocompatibility. As orthodontic treatment is a long-time process, the bonding adhesives also remain in close proximity with intra-oral tissues. Therefore, biocompatibility of these adhesives in respect to their genotoxicity and cytotoxicity should be a concern while clinically implicating them. The aim of this review was to provide information about the genotoxicity and cytotoxicity effects of various orthodontic bonding adhesives. An electronic search was conducted across Cochrane, Medline, Web of Science databases, and Google Scholar for literature analysis on the mentioned topic. The studies were reviewed and compared. This article summarizes the results of research studies that have been done to see the genotoxicity and cytotoxicity of orthodontic bonding adhesives. Most research studies summarized in this review article concluded that orthodontic bonding adhesives show some extent of either genotoxicity or cytotoxicity or both. There is still a lack of scientific literature on long-term in vivo studies on the toxic effects of these adhesives. It is advisable to employ several genetic assays and standardized methods for genotoxic evaluation of bonding adhesives through longtime clinical in vivo studies.

ABSTRAK

Pelekat ikatan ortodontik adalah salah sebahagian daripada rawatan ortodontik. Menggunakan sistem ikatan ortodontik ini, komponen peralatan ortodontik dapat melekat pada permukaan gigi. Pengilang telah memperkenalkan pelbagai jenis pelekat ikatan ortodontik kerana terdapat peningkatan permintaan untuk rawatan ortodontik pada masa ini yang memfokuskan pada sifat fizikal pelekatan ikatan ini. Oleh kerana rawatan ortodontik adalah proses jangka panjang, pelekat ikatan ortodontik mungkin mempunyai hubungan dengan tisu intra-oral mulut. Oleh itu, bioserasi pelekat, dengan tumpuan kepada kegenotoksikan dan kesitotoksikan telah menjadi perhatian apabila diuji secara klinikal. Tujuan kajian ini adalah untuk memberikan maklumat tentang kesan kegenotoksikan dan kesitotoksikan daripada pelbagai jenis pelekat ikatan ortodontik. Carian elektronik dijalankan melalui pangkalan data Cochrane, Medline, Web of Science, dan Google Scholar untuk analisis kepada topik yang disebutkan. Kertas ini merumuskan hasil kajian penyelidikan yang telah dilakukan untuk melihat kesan kegenotoksikan dan kesitotoksikan pelekat ikatan ortodontik. Kebanyakan kajian penyelidikan yang menyimpulkan bahawa pelekat ikatan ortodontik menunjukkan beberapa tahap kegenotoksikan atau kesitotoksikan atau kedua-duanya. Masih kurang keputusan saintifik mengenai kajianin vivo jangka panjang mengenai kesan toksik pelekat ikatan ortodontik ini. Dengan itu adalah disarankan untuk menggunakan beberapa jenis ujian genetik untuk membuat penilaian genotoksik pelekat ikatan ortodontik untuk kajianin vivo klinikal jangka panjang.
