3 MT UNIVERSL - DirectCaps - Technical Product Information PRODUCT DESCRIPTION MT UNIVERSL powder is consisting of very fine hydrophilic particles of se- veral mineral oxides. fter contact with MT UNIVERSL liquid it forms a gel that hardens to an impermeable barrier. During the setting phase release of calcium hydroxide takes place. MT UNIVERSL is suitable for the following indications: - repair of root perforations - root end filling (retrograde) - pulp capping - root end filling (orthograde) ccessories: application gun page 3

4 MT UNIVERSL - DirectCaps - Technical Product Information MT UNIVERSL Features and Benefits Features: biocompatible permanent cement high ph value excellent marginal adaptation thanks to bonding to dentine and very low solubility high radiopacity convenient mix and fixed proportions with capsule Benefits: real biological sealing bacteriostatic by release of calcium hydroxide excellent barrier against bacteria and fluids easy clinical documentation with radiographs very easy to use with excellent handling page 4

5 MT UNIVERSL - DirectCaps - Technical Product Information MT UNIVERSL - Indications MT UNIVERSL in DirectCaps gives a mixed cement with a consistency suitable for all indications given below. Repair of root Perforations Pulp capping Root end filling (orthograde) Root end filling (retrograde) page 5

[mm] Disc diameter of MT Cements MT UNIVERSL DirectCaps Olident Pro Root MT (Dentsply) MT Gray (ngelus) High value for disc diameter means low viscosity. Low value for disc diameter means high viscosity. The photos below show the consistency of mixed MT UNIVERSL after extrusi- on from the capsule. page 6

The prepared roots were sectioned at different levels (thickness of slices 2 mm). The force required to dislodge the MT cement from the root slice was measu- red with a Universal Testing Machine. MT UNIVERSL shows a push-out bond strength in the same range as Pro Root MT. fter removal of smear layer, push-out bond strength was significant- ly reduced.

9 MT UNIVERSL - DirectCaps - Technical Product Information MT CEMENTS - Clinical Studies Pulp Capping Independent clinical studies show that MT is more effective than calcium hydroxide to maintain the vitality of the pulp after direct pulp capping. fter treatment of 149 patients between 2001 and 2006, 108 of them (122 treated teeth) were available for follow up. successful outcome was recor- ded for 78% of teeth (54 of 69) in the MT group and for 60% of teeth (32 of 53) in the calcium hydroxide group.

10 MT UNIVERSL - DirectCaps - Technical Product Information MT UNIVERSL - Competitive Products Beside Pro Root MT (Dentsply) some other products for the same range of indications are listed below: Dentsply ngelus Isasan BioMT Maruchi valon Biomed Septodont Pro Root MT MT-NGELUS, MT-FILLPEX TECH BIOSELER (endo, apex, capping and root end) OrthoMT, RetroMT EndoCem MT MT Plus Biodentine For most of these materials the powder is pre-dosed, but normally these materials have to be mixed by hand on a glass plate. Disadvantages lost of material inhomogeneous mixture time-consuming labor-intensive (cleaning of glass plate and mixing device) EndoCemMT (Maruchi) and Biodentine (Septodent) offer a vial with a pre-dosed amount of powder. fter adding the liquid, the material is mixed in a mixing device. OLIDENT MT UNIVERSL is delivered in easy to mix DirectCaps. fter a mixing time of 30 seconds, the material is extruded from the DirectCap with an optimal consistency. page 10

11 MT UNIVERSL - DirectCaps - Technical Product Information Instruction for activating and mixing DirectCaps DirectCap before activation. For activation of the DirectCap press the plunger on a hard and plane surface to the end into the DirectCap. Insert the DirectCap into the DirectGun and click once to standardize. Note: The plunger must be at the same level as the bottom of the capsule. Insert the DirectCap into a mixer (or an amalgamator), close lid and mix immediately (about 4300 oscillations / min). Mixing time: 30 sec Remove the pin from the nozzle. If not, capsule can burst. Insert the DirectCap into the DirectGun. Pull the lever 2 times (2 clicks) to prime the DirectCap. Extrude the mixed material directly into the preparation. Unlock the gun (push button ) and remove the DirectCap. page 11
