- Brief Summary
The goal of this clinical trial is to evaluate the dental lasers as an alternative of chemical medicaments used in the pulpotomy procedures. The main question it aims to answer is:
• Lasers pulpotomies are a viable alternative to the standard Formocresol and Sodium Hypochlorite medicaments.
All participants groups (Formocresol, Sodium Hypochlorite, Diode and Er:Cr;YSGG lasers) for pulpotomy procedure will follow the same clinical protocol, except for the techniques that will be used for hemostasis of the pulpotomies which either will be achieved by Formocresol or Sodium Hypochlorite solutions or by Diode or Erbium lasers.
- Detailed Description
All the selected treatment groups (Formocresol, Sodium Hypochlorite, Diode and Er:Cr;YSGG lasers) will follow the same clinical protocol, except for the techniques that will be used for hemostasis of the pulpotomies:
1. Using 2 percent lidocaine with 1: 100,000 epinephrine as a local anesthetic.
2. Isolation of the teeth with a rubber dam.
3. Using a diamond round #440 bur in a high-speed hand piece with water cooling to eliminate caries and expose pulp chambers.
4. Using a spoon excavator to remove the coronal pulp.
5. Achieving the hemostasis by:
I. In first group (Group A): using a 1:5 dilution of Buckley's FC solution. A sterile cotton pellet will be moistened with a 1:5 concentration formocresol and it will be placed on the pulp stumps for 5 minutes for achieving hemostasis before being covered with MTA. If hemostasis will not be achieved after 5 minutes, it will presume that the pulp tissue in the canal was infected, and the tooth will be removed from the research.
II. In the second group (Group B): using 3% NaOCl. A sterile cotton pellet will be moistened with a 3% NaOCl and it will be placed on the pulp chamber for 5 minutes for achieving hemostasis before being covered with MTA.
III. In the third group (Group C): In this group hemostasis will be achieved by exposure to diode laser of 940 nm. The laser energy will be introduced into the canal orifice through a 300 µm optical fiber at 2 W, in a contact mode with continuous mode CW (According to the user manual) for 1 second at each orifice for three times to achieve complete hemostasis. During laser application patients, operator and assistant will use protective eye shields according to the safety measures of the device user manual.
IV. In the fourth group (Group D): Irradiation of the floor of the pulp chamber with Er,Cr:YSGG laser 2790 nm ) at a Power of 1.5 w, Frequency of 50 Hz, mode S (soft tissue mode) , 20%air and no water with a gold handpiece and Tip type MZ6, for 10 sec.(According to the manufacturer manual iPlus™ software copyright ©2016 BIOLASE, Inc.). In which a fixed char layer should be formed over the pulpal tissue of the canals orifices. During laser application patients, operator and assistant will use protective eye shields according to the safety measures of the device user manual.
1. Then covering the surface with a 2 mm layer of MTA
2. The final restoration will be completed in all the four groups, stainless steel crown will be placed as the final restorative material with a well-fitting marginal adaption and glass ionomer cement(GC company).

Group Intervention Description second group (Group B) Sodium Hypochlorite Solution using 3% NaOCl(Tahno-dent, Greece) A sterile cotton pellet will be moistened with a 3% NaOCl and it will be placed on the pulp chamber for 5 minutes for achieving hemostasis before being covered with MTA first group (Group A) Formocresol using a 1:5 dilution of Buckley's FC (SSA, Produits Dentaires, Switzerland). A sterile cotton pellet will be moistened with a 1:5 concentration formocresol and it will be placed on the pulp stumps for 5 minutes for achieving hemostasis before being covered with MTA. If hemostasis will not be achieved after 5 minutes, it will presume that the pulp tissue in the canal was infected, and the tooth will be removed from the research third group (Group C) Diode laser In this group hemostasis will be achieved by exposure to diode laser (Biolase, epic X) of 940 nm. The laser energy will be introduced into the canal orifice through a 300 µm optical fiber at 2 W, in a contact mode with continuous mode CW(According to the user manual('EpicX_CAN_UM.pdf', no date) for 1 second at each orifice for three times to achieve complete hemostasis. During laser application patients, operator and assistant will use protective eye shields according to the safety measures of the device user manual.
