简要总结
The study will compare the clinical and radio-graphic performance of newly introduced non-staining bio-active bio-ceramic (Neo MTA 2) versus White MTA used as coronal plug material in revascularization of non-vital immature permanent anterior teeth.Visual examination, palpation, A measuring scale in digital radio-graph software (DIGORA for Windows software) will be used for evaluation.
详细描述
Mineral trioxide aggregate (MTA) has been widely used in revascularization procedures for coronal sealing in more than 85% of studies for privilege of bio compatibility, good sealing properties, and marginal adaptation. However, its poor handling characteristics and potential coronal discoloration effects are the major disadvantages of using mineral trioxide aggregate.
Although white MTA (WMTA) has been developed to overcome the tooth discoloration caused by the application of grey MTA, several in vivo and in vitro studies have also reported tooth discoloration after using WMTA.
To overcome the problems associated with WMTA, a new modification was introduced to the market called NeoMTA 2 as a new hope to overcome the discoloration problem. NeoMTA 2 provides easier handling, shorter setting time, and better color. The lack of post-operative discoloration problems was mainly due to the absence of Bismuth oxide in NeoMTA.
up to date, no clinical trials have reported the clinical and radio-graphic outcomes after revascularization of non-vital immature permanent anterior teeth using Neo MTA 2. Thus, the present study aims to evaluate and compare clinically and radio-graphically the effect of using two different coronal plug materials (Neo MTA 2 versus White mineral trioxide aggregate) in revascularization of non-vital immature permanent anterior teeth.

研究组 & 干预措施
Group I
NeoMTA 2
Manipulation and mixing will be done according to manufacturer instructions:
- 1 scoop (0.1gm) of NeoMTA 2 Powder will be dispensed on a glass slab. Then two drops of NeoMTA 2 Gel will be dispensed next to the powder.
- Gradually as much Gel as necessary will be added to the Powder to achieve the desired consistency. The Gel will be incorporated by spatula-ting the Powder/Gel mixture firmly against the glass slab to ensure all of the Powder is thoroughly witted by the Gel.
干预措施: NeoMTA2 (Drug)
Group II
White mineral trioxide aggregate
- One spoon of powder and one drop of distilled water are dispensed on a sterile glass slab.
- A metal spatula will be used to gradually mix the liquid and powder together for 30 seconds to ensure full wetting of the powder particles and to obtain a consistency similar to wet sand.
- 3-4 mm of white MTA will be placed over the clot carefully by using an amalgam carrier.
The mix will be placed over the collagen matrix 2mm beneath the clinical cement-enamel junction.
干预措施: WMTA (Drug)
