OptiCaps® Especially for root-end filling (retrograde)

Instructions for Use

Applications

Repair of root perforations

Place rubber dam and clean the root canal system using intracanal instruments and irrigate with NaOCl. Dry the root canal with paper points and isolate the perforation.
Fill the root canal apical of the perforation completely with a suitable root canal filling material.
Mix a capsule of Harvard MTA XR Fast OptiCaps® as described under item 1 and extrude it on a glass plate.
Apply Harvard MTA XR Fast with suitable instruments into the perforation site and condense it.
Check the position of Harvard MTA XR Fast in the root canal by an X-ray. If an adequate barrier has not been created, rinse the MTA cement out of the canal and repeat the procedure.
Remove excess moisture with a cotton pellet or a paper point. Place a moist cotton pellet in the access to the root canal and apply a temporary filling material.
Alternatively seal the root canal with a suitable root canal filling material and seal the cavity with a tight filling. Both options can be done at the earliest 3 minutes after placement of the Harvard MTA XR Fast. Harvard MTA XR Fast repair material remains as a permanent part of the root canal filling.

Root-end filling (retrograde)

Create a surgical access to the root-end and resect the root.
Prepare an apical cavity to a depth of 3-5 mm.
Isolate the area and dry the root-end cavity with paper points.
Achieve hemostasis with suitable methods.
Mix a capsule of Harvard MTA XR Fast OptiCaps® as described under item 1 and extrude it on a glass plate.
Apply Harvard MTA XR Fast with suitable instruments and condense it using a small plugger.
Remove excess cement and clean the surface of the root with a moist piece of gauze.
Confirm placement of Harvard MTA XR Fast repair material with an X-ray. Harvard MTA XR Fast remains as a permanent part of the root canal filling.

Pulp capping

Place rubber dam and prepare the cavity. Rinse the cavity and exposed pulpal areas with a suitable disinfectant.
Mix a capsule of Harvard MTA XR Fast OptiCaps® as described under item 1 and extrude it on a glass plate.
With a suitable instrument apply a small amount of Harvard MTA XR Fast over the exposed pulp and remove excess moisture with a cotton pellet.
At the earliest 3 minutes after application of Harvard MTA XR Fast place a small amount of a flowable light cure liner (e.g. Harvard IonoLine) and light cure.
Etch the remaining cavity walls according to the total-etch-technique with Harvard Etch and apply a suitable bonding agent (e.g. Harvard Bond TE Bond) according to the corresponding instructions.
Place a light cure composite (e.g. Harvard PremiumFill) according to the instructions and light cure.
Check pulp vitality and status regularly.

Apexification / Root-end filling (orthograde)

Place rubber dam and clean the root canal system using intracanal instruments and irrigate with NaOCl. Dry the root canal with paper points.
For disinfection place calcium hydroxide paste in the root canal and seal the access opening with a temporary filling material.
After one week remove the calcium hydroxide paste from the root canal system.
Mix a capsule of Harvard MTA XR Fast OptiCaps® as described under item 1 and extrude it on a glass plate.
With a suitable instrument apply a small amount of Harvard MTA XR Fast into the apical region and condense it. Create a 3 – 5 mm barrier of MTA cement.
Check the position of Harvard MTA XR Fast by an X-ray. If an adequate barrier has not been created, rinse the MTA cement out of the canal and repeat the procedure.
At the earliest 3 minutes after application of the Harvard MTA XR Fast place a cotton pellet in the access to the root canal and apply a temporary filling material.
Alternatively seal the root canal with a suitable root canal filling material and seal the cavity with a tight filling.
