Radicular canal disinfection by photosensitizers activated by photodynamic therapy and Er, Cr: YSGG laser bonded to glass fiber post using different cement types. An Invitro study.

Aim: To assess the tensile bond strength (TBS) of conventional glass ionomer cement (GIC) and resin cemented fiber post to radicular dentin when disinfected with different photosensitizers methylene blue photosensitizer (MBP), curcumin photosensitizer (CP), and laser therapy Er, Cr: YSGG laser (ECYL) MATERIAL AND METHODS: Sixty carefully extracted, non-traumatic, non-carious, closed apex human mandibular premolars were collected. Periodontal fibers, plaque, or calculi were detached. Decoration of samples was executed up till the cementoenamel junction.
