Effectively improves wear resistance and marginal integrity of composite restorations

• Low viscosity modified BIS-GMA resin base with THFMA - for increased hydrophobicity and resistance to hydrolytic degradation and durability.
• Light cured - conforms to ISO 6874
• Low viscosity allows for air brushing and seals the smallest margins
• Highly transparent, allows for easy monitoring of underlying activity
• Very low oxygen inhibited layer

Instructions for use

DESCRIPTION

Resist is a low viscosity, unfilled resin that is cured by visible blue light. It is designed for use as a pit & fissure sealant but may also be used to seal the margins around composite restorations. Resist has a very thin oxygen inhibited layer.

INDICATIONS

Resist is indicated for use as a pit and fissure sealant for children & adults who (i) may be at moderate or high risk of developing dental caries, (ii) have incipient caries that are limited to the enamel of pits & fissures, (iii) have existing pits and fissures that are anatomically susceptible to caries, or (iv) have sufficiently erupted permanent teeth with susceptible pits and fissures.

INSTRUCTIONS

Preparation: Perform a prophylaxis on the area to be sealed using a prophylaxis paste that does not contain fluoride or oil. Rinse the area thoroughly with water. Once clean, isolate the area with cotton rolls or a rubber dam. Dry the teeth with uncontaminated air.

Note that inadequate isolation and subsequent contamination is the most common reason for failure of a sealant.

Etching: Etch the area with BDT’s Etching Gel or similar 37% phosphoric acid etch for 15-20 seconds. The air dried etched areas should appear dull and frosty white. If not, re-etch them. Teeth with high fluoride content and some primary teeth may require longer etching times. Note that etching solutions may not penetrate deep recesses and that these may also contain some debris. It is therefore suggested that these areas be cleaned and prepared with a burr or air abrasion to allow penetration of the sealant. Do not allow the etched surfaces to be contaminated with moisture as this may cause the restoration to fail.

Placement: Apply sealant to the occlusal surfaces taking care not to create air bubbles.

Curing: Cure the sealant for 20 seconds with a reputable visible light curing light held 1-2mm away from the surface.

Finishing: Once the sealant has set, wipe the surface with cotton gauze to remove any unpolymerised resin. If desired, a high gloss can be achieved using a felt wheel or fine rubber cups and points. Do not over polish.

Follow up: Examine the condition of the sealant at six months and reapply sealant to any exposed areas
