Fjalë kyçe

Përshkrim
This will be a randomized single blind clinical trial. Setting and conduct: Twenty caries free premolar teeth from fifteen patients assigned for orthodontic extraction will be included. Participants including major eligibility criteria: Their parents need to sign an informed form, Patients shouldn't have any systematic complication, The teeth should be free of any symptom, caries and decalcification and should reveal a normal response to pulp sensitivity tests, No mobility or swelling in the surrounding soft tissues, sensitivity on palpation or percussion should be present. Intervention: A class one cavity will be prepared and the depth will be increased until the pulp exposure occurs. One millimeter of the coronal pulp will be removed. Then the exposure site will be covered using two pulpotomy agents: White ProRoot MTA as control group and iRoot BP. After six weeks (42 days) the teeth will be extracted after radiographic and clinical examination to find any sign of swelling, abscess or sinus tract. Main outcome measures (variables): The teeth will be sectioned and examined to compare the presence of dentinal bridge, its thickness and feature in the terms of tunnel defect formation. The underlying pulp will be assessed and graded according to the degree of inflammation as follows: grade 0 no inflammation, grade 1 mild inflammation, grade 2 moderate inflammations, grade 3 severe inflammation, grade 4 abscess formation or necrosis. Our criteria are based on ISO 7405.

Experimental: iRoot BP Partial pulpotomy using iRoot BP. Partial pulpotomy includes removal of 1mm of coronal pulp and covering the remaining tissue with a suitable material. Bioaggregate is the first nano particle, water based root end filling material. This product includes calcium silicate, calcium hydroxide, hydroxy apatite and Tantalum oxide. Compared to MTA,this material lacks Bismuth oxide and calcium aluminate. iRoot BP is the injectable for of Bioaggregate (Injectable Root Bioaggregate Paste). | Drug: iRoot BP Partial pulpotomy using iRoot BP.
