Ammdent LC Cal Excel Light Curing Radiopaque Calcium Hydroxide

Ammdent Root Plus MTA

Ammdent Root Plus MTA is a mineral trioxide aggregate–based repair material composed of very fine hydrophilic particles of multiple mineral oxides. When mixed with ROOT PLUS liquid, it forms a gel that hardens into an impermeable barrier, providing an excellent seal and long-term biological compatibility.

Root Plus MTA is indicated for a wide range of endodontic repair procedures including perforation repair, root-end fillings, apexification, and pulp capping. It sets even in the presence of moisture or blood and promotes regeneration of hard tissues.

Composition :

• Powder consisting of fine hydrophilic mineral oxides
• Forms a gel with ROOT PLUS liquid that hardens into an impermeable barrier

Indications :

• Repair of root perforations during root canal therapy
• Root-end filling (retrograde)
• Root-end filling (orthograde)
• Pulp capping

Advantages :

• Antimicrobial activity
• Non-toxic and non-mutagenic
• Vasoconstrictive effect supporting hemostasis during pulp capping
• Excellent long-lasting sealability
• Low solubility
• Sets in the presence of moisture or blood
• No dimensional changes during setting
• Minimal microleakage with no setting shrinkage
• High clinical success rate
• Alkaline pH with antibacterial effect
• Induces formation of dentin, cementum, bone, and periodontal ligament
• Excellent biocompatibility and mechanical properties
• Creates an artificial barrier for obturation
• Higher radiopacity than calcium hydroxide

Features :

• Good compressive strength
• Calcium ion release enhancing mineralized tissue formation
• Hydrophilic – suitable for humid clinical conditions
• High alkalinity for antibacterial properties
• Low solubility preventing leakage
• Calcium oxide content promotes biocompatibility
• Aggregated oxides provide excellent compressive strength
• High radiopacity for clear radiographic visualization

Key Specifications :

• Storage temperature: 10–25 °C (50–77 °F)
• Do not store below 10 °C
• Do not use after expiry date

Packaging :

• 1 × 1 g powder
• 1 × 3 ml liquid

Direction to Use :

Dispensing and Mixing :

• Recommended powder/liquid ratio: 26 : 1
• Mix 1 level scoop of powder with 2 drops of liquid
• For thinner or firmer consistency (orthograde), use a 2 : 1 ratio by weight
• Mix 3 level scoops of powder with 8 drops of liquid
• Mix on a water-impervious mixing pad or glass slab
• Total mixing time: approximately 30 seconds
• Final mix should be thixotropic and homogeneous

Repair of Root Perforations :

• Isolate with rubber dam and clean canal using NaOCl
• Dry canal and isolate the perforation
• Fill apical canal space up to the perforation
• Mix and apply ROOT PLUS MTA to the perforation site
• Condense and verify placement radiographically
• Place a damp cotton pellet and seal temporarily
• Permanent restoration may be completed after 5 minutes

Root-End Filling (Retrograde) :

• Resect root end and prepare a 3–5 mm cavity
• Dry and achieve hemostasis
• Apply and condense ROOT PLUS MTA
• Remove excess material and confirm placement with X-ray

Pulp Capping :

• Isolate and disinfect exposed pulp
• Apply a small amount of ROOT PLUS MTA
• Cover with a flowable liner and light cure
• Proceed with bonding and composite restoration

Root-End Filling (Orthograde) :

• Disinfect canal and place calcium hydroxide for one week
• Apply ROOT PLUS MTA to create a 3–5 mm apical barrier
• Verify placement radiographically
• Seal temporarily or permanently after 5 minutes
