Study summary

The purpose of this study was to compare the conventional and diode 808 nm laser-assisted techniques in direct pulp capping in permanent teeth .The present study was based on a series of ten clinical studies with pulp exposure caused by carious lesions.The hypothesis of this paper was laser supported direct pulp cap-ping has proven effectiveness by its capacity to stimulate reparative dentine formation by pulp cells, de-contamination ability of irradiated areas, its ability in the fast and better haemostatic, and pain reduction.

Groups and cohorts

  • conventional group,RM-GIC

    1. Group A: Five teeth were treated with traditional rotating instruments, the cavities were prepared with diamond drills by turbine, multiple-blade drills by headpiece for removing the decayed dentine and, after cleaning and control of bleeding with cotton pellets with saline solution,RM-GIC (3M ESPE, USA) light-hardening paste was placed gently on the exposed part of the pulp and cavity floor next final restoration with composite z350 flow able and p60 (3M ESPE, USA).

  • Diode 808 nm laser-assisted group

    2. Group B : Five teeth cavities were prepared as the same with group one with traditional rotating instruments, hemostatic and cavities sterilization were achieved by a diode 808 nm (Picasso- AMD, USA) laser using following parameters: * Hemostatic: 1.5 W, CW, fiber diameter 400µm, in contact, 2s per 1mm, vertical and horizontal scanning movement on exposure site. * Cavity sterilization: 1W, CW, fiber diameter 400µm, in contact, 2mm per s, circular movement. After hemostatic and cavity sterilization, RM-GIC (3M ESPE, USA) light-hardening paste was placed on the exposed part of the pulp and cavity floor next final restoration with composite z350 flow able and p60 (3M ESPE, USA).

What researchers measure

Primary outcomes

  1. Maintenance of teeth vitality was be measured via thermal tests also by radiographic.

    Given low success rate of conventional methods, new techniques as laser-assisted need to be developed.The outcome measure of this study was maintenance of teeth vitality with carious exposed via tertiary dentine formation.the tertiary dentine formation during the time of study was assessed radiological. Therefore vitality of the teeth was depend on dentine formation that was measured periodically in 1,6 and 12 months.

    Time frame: up to 12 months
