In this study, patients with symptoms of irreversible pulpitis in mature permanent molars were treated with two pulpotomies techniques after random allocation in either 2 groups: Diode laser pulpotomy and traditional pulpotomy using bioactive materials (retro mineral trioxide aggregate ) with each group.The null hypothesis of the study was there would be no difference in success rate between Diode laser and traditional methods of adult pulpotomy .
In this study, 40 patients with symptoms of irreversible pulpitis in mature permanent 1st and 2nd molars were treated with two pulpotomy techniques after random allocation in either 2 groups: traditional pulpotomy and low-level diode laser pulpotomy. The pulp in each group was capped with Retro MTA . In the traditional pulpotomy group, the coronal pulp was removed by the traditional method while in the low-level diode laser pulpotomy group, the radicular pulp was biostimulated using low-level diode laser beam with parameters (970nm, power .5Watt, duty cycle 50%, and frequency 5H) 10 sec for each pulp stump in non-contact mode. After that, the capping material was prepared as manufacturer's instructions and applied over the pulp stamp, the final restoration was then placed in both groups. Patients were followed up after 6, 12, and 18 months to evaluate success and failure.

After complete deroofing, the coronal pulp was amputated to the level of the orifice using a high-speed size #2 round bur followed by rinsing the pulp chamber thoroughly with 5ml 0.9% saline solution.Hemostasis was then achieved by placing a sterile cotton pellet moistened with saline in the access cavity for 6 min.Retro MTA capping material was then applied,
after establishing hemostasis, low-level laser energy at (970nm, power .5W, duty cycle 50%, and frequency 5H) was applied to each pulp stump for 10 sec. through 320 microns optical fiber tip . The laser was used in pulsed non-contact mode at the level of the occlusal surface of the tooth.Retro MTA capping material was then applied,

Assessment of success or failure
Assessment of success or failure was done using the technique described by Galeni et al Treatment was considered successful if the patient's final restoration was intact and the patient demonstrated no clinical symptoms (pain (spontaneous or on chewing), swelling, or sinus tract), and had a periapical index score of 1. • Treatment was considered uncertain if the patient's final restoration was intact, and the patient demonstrated no clinical symptoms (pain (spontaneous or on chewing), swelling, or sinus tract), and a PAI score of 2. • Treatment was considered a failure in the following situations: 1\. Any case in which the final restoration was not intact. Irrelevant clinical and radiographic symptoms. 2\. Any case in which the final restoration was intact and the patient demonstrated clinical symptoms. Irrelevant of PAI score. 3\. Any case in which the final restoration was intact and the patient had a PAI score of 3 or above. Irrelevant of clinical symptoms.
Time frame: (T1): 1 week postoperative, (T2): after 6 months, (T3): after 12 months, and (T4) after 18 months.
