Effect of Low-Level Laser Therapy Following Direct Pulp Capping on Postoperative Sensitivity by Thermal Stimulus

The aim of this study was to investigate the effect of low-level laser therapy (LLLT) on postoperative pain provoked by thermal stimulation in direct pulp capping. All the patients who received consent form in this retrospective study were retrieved from the records of patients attended for routine dental treatment at the Ordu University, Faculty of Dentistry, Department of Endodontics between 01.10.2017-01.10.2018. Study subjects were recruited from the pool of patients who performed direct pulp capping by a single operator. A total of 123 pre-treated teeth of 123 patients who referred to Ordu University, Faculty of Dentistry were examined. Follow-up examinations were carried out at postoperative 6th hours, 1st and 7th days with visual analog scale (VAS), and treatment outcome were assessed. Participants were allocated to the laser and control group which consist of 42 patients in each group. 6 patients were excluded from the study due to missing data in both groups. Thus, data from 72 patients who had been carried out direct pulp capping were assessed.

Treatment and study plan

Low-Level Laser Therapy

Device

The low-level laser was applied to each patient in low-level laser therapy group.

Primary outcomes

Effect of low-level laser therapy following direct pulp capping on postoperative sensitivity as assessed by visual analog scale.

Time frame: 7 days

Postoperative sensitivity was assessed and documented via a visual analog scale. The visual analog scale consists of a 100 mm line which is represented at one end by a sign 'no pain' and at the other end 'unbearable pain'. This form was given to each patient and instructed to mark at home according to the pain intensity at 6th hours. Also, patients were seen 1 and 7 days postoperatively to mark the degree of pain on the visual analog scale. Patients were informed that the marking must be performed only when sensitivity induced by the cold stimulus. On a visual analog scale named postoperative sensitivity scale, '0' presents the minimum value and '10' presents the maximum value. High scores indicate a worse result, while low scores indicate a better result. Lower sensitivity was detected on the visual analog scale at 7th days in the low-level laser therapy group compared to the control group.
