Online published on 30 April, 2019. Abstract New tissue formation in the pulp chamber can be observed after adequate infection control and the formation of a blood clot. Low-power lasers have been successfully used in dental practice, and it is known that wound healing is accelerated by their irradiation. Collagen has a potent hemostatic property and ability to aggregate platelets, that facilitates wound maturation by It is chemotactic for fibroblasts and improves their migration and attachment through its fibrillar structure. This property may enhance cell migration into the space between collagen membrane and the pulp wound. The study was conducted to evaluate pulp response to direct capping with collagen with and without laser exposure by histological and histomorphometric analysis. Direct pulp capping procedure was performed on 40 rabbit incisors which were divided into control (10 teeth capped by mineral trioxide aggregate) and experimental groups (10 teeth exposed to laser and sealed by MTA), (10teeth capped by collagen), (last 10 teeth capped by collagen and exposed to laser) for 1 and 4 weeks periods. Histological findings showed variable response of pulp tissue to the applied agents throughout the follow up healing periods as compared to control groups where only mineral trioxide aggregate (MTA) was applied to seal off the exposed pulp. Non-significant differences recorded among the studied groups in duration comparison. There was no significant difference between the Collagen group and Coll/Laser groups.
