The aim of this in vitro study was to investigate the potential of CO2 laser (10.6 µm) associated with fluorides in inhibiting enamel erosion. Human enamel samples were divided into 9 groups: G1: eroded enamel , G2: APF gel, G3: AmF/NaF gel, G4: AmF/SnF2 solution, G5: CO2 laser ( =10.6 µm) + APF gel, G6: laser + AmF/NaF gel, G7: laser + AmF/Sn F2 solution, G8: laser and G9: sound enamel. The CO2 laser parameters were: 0.45J/cm2, 15mis, 128Hz. After surface treatment, samples (except group G9) were immersed in 1% citric acid (pH 4.0, 3min). Knoop Surface microhardness (SMH) (0.49N, 20s) was measured at baseline and after surface softening. Data were statistically analyzed by ANOVA with subsequent pairwise comparisons (p 0.05). It was concluded that AmF/NaF and APF application have shown a potential to protect and control erosion progression in dental enamel and that CO2 laser irradiation at 0.45J/cm2 did not influence its efficacy. Solely CO2 laser at the same conditions may also significantly decrease enamel erosive mineral loss, although at lower levels.

Results of first part of the study is evaluation of firmly bound & loosely bound fluoride. The purpose of this study was to evaluate the amount of loosely bound fluoride and firmly bound fluoride formed after the application of APF gel and laser activated APF gel in acidic and neutral pH at different time intervals and also to compare and evaluate the pulpal response of 810nm diode laser to different power and duration (2W & 3W for 5secs ,15secs & 30secs) in laser assisted fluoride therapy. The study on pulpal response gives an overall impression of maximum inflammatory cell infiltrate in 810nm diode laser treated at a power of 2W for 5sec, animals treated at a power of 2W & 15sec showed the pulp was affected the least whereas only one animal showed minimal inflammatory cell infiltration. Animals treated at 3W & 15sec showed less inflammatory cell infiltration though dentin demineralisation was observed and in animals treated with 3W power and 30sec, only 1 animal had exhibited minimal inflammatory cell infiltration and cellular congestion.
