Evaluation of Success Rate of Partial Pulpotomy Versus Complete Pulpotomy in Primary Molars Using NeoPUTTY MTA

Children with symptoms of reversible pulpitis in their second primary molar will be chosen to be enrolled in the study, and then randomly allocated into two groups. One group will undergo partial pulpotomy and the other group complete pulpotomy and followed up for 12 months. The blinding of the operator is not possible due to the nature of the technique used. Trial participants, outcome assessors and statistician will be blinded.

1. Informed consent from participating children's parents.
2. Baseline records photographs, percussion test, periapical radiograph and personal data collection.
3. Diagnostic chart with personal, medical and dental history will be filled.
4. Allocation (concealed by withdrawing a sealed opaque envelope containing Four-folded numbered papers containing the type of vital pulp therapy technique that will be used then writing the patient's name and I.D. on it and will be opened after removing the carious lesion).
5. Clinical examination will be performed to assess the clinical inclusion criteria. (Pulpal and periapical diagnoses are established after clinical examination).
6. Preoperative and Postoperative photographs will be taken.

• Partial Pulpotomy (Procedure): After removing caries high-speed handpiece with water coolant using a round diamond bur. Once there is an exposure, the bur is changed with another sterile one with which the superficially inflamed pulp tissue will be gently removed to a depth of 1-3 mm beneath the pinpoint pulp exposure that occurred at the end of caries removal. A sterile cotton pellet with saline will be placed with light pressure for 2-3 minutes to achieve hemostasis.
• Complete pulpotomy (Procedure): After removing caries with a large round bur, the access cavity will be opened. Excavation of inflamed coronal pulp tissues will be done using a sharp excavator. A sterile cotton pellet with saline will be placed with light pressure for 2-3 minutes to achieve hemostasis.

Primary outcomes

• Postoperative pain [one week postoperative]: Postoperative pain assessment through Visual Analog Scale (the lower the value the better).
• Swelling/ Fistula [3, 6, 9, 12 months]: Assessment of swelling and fistula through visual examination.
• Mobility [3, 6, 9, 12 months]: Assesment of pathological mobility using mobility test.

Secondary outcomes

• Radiographic success [0, 6, 12 months]: Radiographic evaluation (Radiolucency at furcation or periapical, internal or external root resorption) through visual interpretation of digital radiograph at 0, 6 and 12 months postoperatively.
