Orthodontic intervention as an aid in restorative dentistry.

The successful treatment of patients with multiple problems can be achieved with a multidisciplinary approach. Orthodontics as part of an integrated treatment plan can significantly enhance a favorable result. The intent of this article was to provide insight into the range of treatment options available.

Microscopic evaluation of the thickness of sealants used in orthodontic bonding.

Placement of a resin sealant on the enamel surface prior to orthodontic bracket bonding has been suggested as a means of providing protection against demineralization, particularly at known sites of plaque accumulation. The duration of protection is influenced by resin sealant thickness and distribution. The object of this study was to determine the thickness of polymerized sealant at the vulnerable bracket/resin periphery. Six groups of ten extracted caries-free teeth were bonded with metal brackets using six commercially available bonding materials and their respective sealants. Scanning and light microscopy were used to map sealant distribution and measure sealant thickness at the bracket/resin periphery. Results showed a wide range of sealant thickness, from 0 to 228 micrometers, with considerable intraproduct variation. It was concluded that thin resin films, with their low abrasion resistance, cannot be expected to provide long-standing protection against demineralization.

An ultraviolet photographic technique for monitoring plaque during direct bonding procedures.

An ultraviolet-light dental camera was used to disclose plaque in relation to directly bonded plastic orthodontic brackets. No disclosing solution was used. The reestablishment of plaque patterns 14 days after a prophylaxis and in the presence of the brackets was noted. A further cleaning after debonding removed the plaque, which returned to the base line pattern within 14 days. Small resin remnants left during debonding did not form foci for plaque growth and spread over a 6-month observation period.
