RETENTION OF THE ORTHODONTIC BANDS... IN VITRO STUDY - authored by DR. PRIYA K, MDS.



Orthodontic band has been in clinical use for more than 100 years. In spite of the wide spread use of direct bonded brackets and tubes in clinical orthodontics, the convent ional band st ill plays an important role in fixed appliance therapy. 


Alt hough bonding of orthodontic tubes to the teeth is receiving much current interest in the form of indirect bonding, the vast majority o f buccal attachments are still being cemented using stainless steel bands and convent ional cements, considering the force levels in the posterior region. Enamel demineralizat ion under orthodontic bands is a serious, but a common problem to all orthodontists. White spot formation or enamel decalcification can occur whenever bacterial plaque is retained on enamel surface for a prolonged period.



By the presence of fixed appliance the efficiency of home prophylactic procedure is great ly reduced and there is a need for protection of adjacent enamel surface. Inadequate bonding strength of dental cement, seal break down, solubility of the current ly used dental cements in oral fluids and poor oral hygiene all contribute to the init iat ion of decalcification.



Several studies in the past have invest igated the chemical co mposit ion of various cements, their physical and chemical properties and their applicat ion as well as use in restorative dentistry.



The retent ion of orthodontic bands to the tooth surface is important to ensure fixed appliance therapy. Numerous agents have been used to retain orthodontic bands. Gutta percha, zinc oxide eugenol, zinc polyacrylate cement, zinc polycarboxylate cement, resin based cements, zinc silicophosphate and black copper cement have all been investigated. More recent ly attention has been focused on glass ionomer cement.
