Evaluation of Pulpotomy Success of Different Methods

The study was carried on 65 patients (33 females and 32 males) with ages ranging between 5-9 years and having no systemic disease. Inclusion criteria were as follows; deep dentin caries, lack of spontaneous pain, no sensitivity to percussion and palpation, no soft tissue pathologies such as edema, fistula, abscess, mechanical exposure greater than pinpoint, carious exposure, suitability for restoration with stainless steel crowns, healthy lamina dura and periodontal space, no radiographic pathologies in the interradicular and periapical regions, no pathological external and internal resorption, and no calcified masses within the pulp. Only the mandibular primary molars were included in the study to evaluate the roots better radiologically. A single physician performed all patients' treatments. Following administration of local anesthesia, the teeth were isolated by a rubber dam. The carious enamel tissue was removed and the cavities were formed using a high-speed rotary instrument under water cooling. The carious dentin was removed using a low-speed rotary instrument and steel round bur. In the teeth included in the study, after opening the access cavity, the coronal pulp was removed with a sharp, sterile excavator and low-speed rotary instrument, and the pulp chamber was rinsed with saline. Primary bleeding control was provided in all groups by applying moisturized sterile cotton pellets over the canal orifices for five minutes with minimal pressure. The teeth in which bleeding could not be controlled within five minutes were excluded from the study, and root canal treatment was performed in these teeth. In the teeth that bleeding control was provided, FS, ABS, or Er,Cr:YSGG laser applications were made according to the order on the randomization list.

Following the primary bleeding control, the FS solution was kept in the cavity for 15 seconds using cotton pellets in the FS group. The ABS solution drawn from the 1 ml ampoule to the syringe according to the manufacturer's instructions, was kept in the cavity for 15 seconds using cotton pellets in the ABS group. In the laser group, both the physician and the patient wore protective glasses before the procedure. Er,Cr:YSGG laser (Waterlase MD, Biolase, USA) was applied in a non-contact manner on the pulp tissue. In all groups, after secondary bleeding control, the pulp chamber was sealed with zinc oxide -eugenol (ZOE). Glass ionomer cement was applied over the ZOE base and teeth were restored with stainless steel crown. Following the treatment, the patients were called for follow-up examinations at intervals of 3 months for 12 months.
