Extended fissure sealants: An adjunctive aid in the prevention of demineralization around orthodontic bands

Liebenberg

Pages: 303-312
PMID: 7938414

Banding of molars is still the attachment mode of choice to the majority of clinical orthodontists. One of the acknowledged hazards of orthodontic treatment continues to be the presence of clinicaly detectable areas of enamel demineralization following the removal of orthodontic appliances. Factors that contribute to this demineralization include inaccurate adaptation of the bands and breakdown of the seal as a consequence of the inadequate bonding strength of the cements and their solubility in oral fluids. Traditional cleaning methods limit adequate plaque control to those areas gingival and incisal to the cemented bands. The iatrogenically created defective band-tooth interface areas pose particular problems, because the ingress of food particles and bacterial plaque make these areas prone to demineralization. A technique is introduced whereby fissure se alant is extended to cover the entire occlusal perimeter, effectively sealing the band-tooth circumferential interface. This technique represents an additional method of prophylaxis against the demineralization that can accompany orthodontic intervention
