About this study
Official title: Laser-assisted Versus Conventional Total Pulpotomy for Postoperative Pain and Clinical-Radiographic Outcomes in Mature Molars With Symptomatic Irreversible Pulpitis: a Randomized Controlled Trial
his randomized controlled clinical trial will compare laser-assisted total pulpotomy with conventional total pulpotomy in permanent molar teeth diagnosed with symptomatic irreversible pulpitis. Participants will be randomly assigned to one of two treatment groups. In the conventional group, bleeding control will be achieved using sodium hypochlorite, whereas in the laser-assisted group, an Er:YAG laser will be used for hemostasis. In both groups, Biodentine will be placed over the remaining pulp tissue and the tooth will be permanently restored.
Postoperative pain will be assessed using a visual analog scale at 6, 12, and 24 hours and on days 3, 5, and 7 after treatment. Clinical and radiographic outcomes will also be evaluated during follow-up to determine treatment success. The study aims to determine whether laser-assisted total pulpotomy differs from conventional total pulpotomy in terms of postoperative pain and clinical and radiographic outcomes.
Read the detailed description
Symptomatic irreversible pulpitis is commonly associated with spontaneous or prolonged pain; however, the presence of severe symptoms does not necessarily indicate that the entire pulp has lost its capacity for healing. Total pulpotomy is a vital pulp treatment intended to preserve the remaining radicular pulp tissue while removing the inflamed coronal pulp. The use of Er:YAG laser irradiation may provide additional hemostatic and tissue-related effects during vital pulp treatment.
In this prospective randomized controlled clinical trial, eligible participants aged 12 to 40 years with permanent molar teeth diagnosed with symptomatic irreversible pulpitis will be randomly allocated to conventional total pulpotomy or laser-assisted total pulpotomy. After local anesthesia, rubber dam isolation, caries removal, and removal of the coronal pulp tissue to the level of the canal orifices, the assigned hemostasis protocol will be performed.
In the conventional total pulpotomy group, hemostasis will be achieved using a cotton pellet moistened with 2.5% sodium hypochlorite. In the laser-assisted group, hemostasis will be achieved using an Er:YAG laser. After hemostasis, approximately 2 mm of Biodentine will be placed over the pulp tissue, followed by a glass ionomer base and composite resin restoration in both groups.
Postoperative pain intensity will be recorded using a visual analog scale at 6, 12, and 24 hours and on days 3, 5, and 7. Clinical follow-up will include assessment of spontaneous pain, percussion and palpation tenderness, swelling or sinus tract formation, and abnormal mobility. Radiographic evaluation will assess the periapical and furcation regions. Clinical follow-up visits are planned at 3, 6, and 12 months, with radiographic evaluation at baseline and 12 months. Treatment will be considered successful when predefined clinical and radiographic success criteria are met.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Conventional Total PulpotomyProcedure or surgery
Following removal of the coronal pulp tissue to the level of the canal orifices, initial bleeding control will be performed using a saline-moistened cotton pellet. Hemostasis will then be achieved using a cotton pellet moistened with 2.5% sodium hypochlorite for 2 minutes and repeated if necessary, without exceeding a total application time of 5 minutes. After hemostasis, approximately 2 mm of Biodentine will be placed over the remaining pulp tissue, followed by a glass ionomer base and composite resin restoration.
Laser-Assisted Total PulpotomyProcedure or surgery
Following removal of the coronal pulp tissue to the level of the canal orifices, initial bleeding control will be performed using a saline-moistened cotton pellet. Hemostasis will then be achieved using an Er:YAG laser (2940 nm) with an H14 handpiece in SP mode at 20 mJ, 15 Hz, and 0.3 W. The laser will be applied approximately 1 mm from the pulp surface using a sweeping motion for 15 seconds and repeated until complete hemostasis is achieved. After hemostasis, approximately 2 mm of Biodentine will be placed over the remaining pulp tissue, followed by a glass ionomer base and composite resin restoration.
| Study group | Role | What they receive |
|---|---|---|
| Conventional Total Pulpotomy | Active comparator | Participants assigned to this arm will receive conventional total pulpotomy. After removal of the coronal pulp tissue, initial bleeding control will be performed with a saline-moistened cotton pellet, followed by hemostasis using a cotton pellet moistened with 2.5% sodium hypochlorite. After hemostasis, approximately 2 mm of Biodentine will be placed over the remaining pulp tissue, followed by a glass ionomer base and composite resin restoration. Receives: Procedure: Conventional Total Pulpotomy |
| Laser-Assisted Total Pulpotomy | Experimental | Participants assigned to this arm will receive laser-assisted total pulpotomy. After removal of the coronal pulp tissue, initial bleeding control will be performed with a saline-moistened cotton pellet, followed by hemostasis using an Er:YAG laser. After laser-assisted hemostasis, approximately 2 mm of Biodentine will be placed over the remaining pulp tissue, followed by a glass ionomer base and composite resin restoration.

What is being measured
The primary outcome is the main question the study is designed to answer.
Postoperative Pain Intensity
Postoperative pain intensity will be assessed using a 0-10 visual analog scale (VAS), where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity. Participants will record their pain scores using the provided follow-up forms.
Measured: 6, 12, and 24 hours and 3, 5, and 7 days after treatment
Secondary outcomes (2)
Clinical Success of Total Pulpotomy
Clinical success will be assessed based on the absence of spontaneous pain, tenderness to percussion or palpation, swelling or sinus tract formation, and increased pathological mobility. Teeth meeting all predefined clinical success criteria will be considered clinically successful.
Measured: 3, 6, and 12 months after treatment
Radiographic Success of Total Pulpotomy
Radiographic success will be assessed using periapical radiographs. Success will be defined as the absence of new furcation or periapical lesions, maintenance of lamina dura continuity, and, when a mild pre-existing lesion is present, evidence of radiographic healing.
Measured: 12 months after treatment
