简要总结
pulpotomy will be done I primary molars with occlusal or proximal decay and level of cytokines will be measured as an indicator for pulp inflammation levels
详细描述
The proposed trial interventions, pulpotomy, will follow standard clinical procedural guidelines. Participants will be allocated to one of the two intervention groups only after intra-operative confirmation of pulp vitality and achievement of radicular pulp hemostasis.
Standard clinical protocol for both groups with occlusal and proximal decay:
- A detailed history of symptoms will be obtained, and a thorough clinical examination will be conducted.
- Pre-operative pain intensity will be assessed using a validated five-face visual analog scale (VAS), where children select the face that best represents their pain level.
- A standard pre-operative periapical radiograph will be taken, ensuring the image extends beyond the root tip and shows no distortion or processing errors.
- Local anesthesia will be administered, and the tooth will be isolated with a rubber dam.
- To minimize further bacterial contamination, carious tissues will be removed progressively, starting from the cavity periphery and then over the pulp chamber roof.
- Before managing the pulpal hemorrhage, a sterile cotton pellet will be placed over the pulp tissue for 30-45 s. to obtain pulpal blood samples. The specimens will be collected into heparin-coated tubes with 1 mg saline solution and stored at - 20 °C (-4.0 °F) for 6 months until the day of testing.
- A fresh sterile bur will be used to remove all coronal pulp tissue down to the root canal orifices, with copious water irrigation. Intra-operative assessment of pulp vitality will be conducted, with healthy vital pulp appearing as uniformly reddish-pink vascular tissue and non-vital pulp as dark avascular tissue or yellowish liquefied areas. If necrotic, the tooth will be excluded from the study, and local management protocols will be followed for treatment (Bas et al., 2024).
- MTA will be used as medicament of choice for pulpotomy.
- Once a 2-3 mm thickness is ensured, the cavity will be filled with restorative glass ionomer cement to seal it.
- The pulpotomy-treated tooth will be prepared to receive a full-coverage stainless steel crown (SSC) after the procedure.

结局指标
主要结局
Post operative Pain
时间窗: pain will be measured at one week , 3 months , 6 months and 12 months.
The Visual Analogue Scale (VAS) measures pain intensity. The VAS consists of a 10cm line, with two end points representing 0 ('no pain') and 10 ('pain as bad as it could possibly be'). Ask the patient to rate their current level of pain by placing a mark on the line. Use a ruler to measure the distance in centimetres from the 'no pain marker' (or zero) to the current pain mark. This provides a pain intensity score out of 10; for example, 6 out of 10 (or 6/10).
Preapical lesion
时间窗: will be measured at 3 months , 6 months and 12 months
by Clinical examination: presence of Swelling, sinus tract, or fistula: ,(binary outcome: present or absent )
Pain on percussion
时间窗: will be measured at 3 months , 6 months and 12 months
Tapping the tooth with the blunt end of the mirror binary outcome: present or absent
Mobility
时间窗: will be measured at 3 months , 6 months and 12 months
using Miller's mobility test :involves holding the tooth firmly between two instruments and assessing its mobility on a scale from 0 to 3. A score of 0 indicates no detectable movement, while scores of 1-3 represent increasing degrees of mobility. it will be measured as present for any score from 1 to 3 (binary: present or absent)
次要结局
- radiographic success(baseline data at the first visit following the procedure completion and at 6 and 12 months)
- Cytokines level(at the time of pulpotomy procedure)
