Resumo IPEN-doc 07936 Efeitos termicos da irradiacao intracanal do laser de Nd:YAG1999 - STREFEZZA, C.; ZEZELL, D.M.; BACHMANN, L.; CECCHINI, S.C.M.; PINOTTI, M.; EDUARDO, C.P.Resumo IPEN-doc 08048 Effects of holmium laser on dental structure in vivo2001 - STREFEZZA, C.; BACHMANN, L.; BAUER, J.A.; ANTONIAZZI, J.H.; EDUARDO, C.P.; ZEZELL, D.M.Provious in vitro has demonstrated that Ho:YLF laser is capable of inducing physical and chemical changes on dental surfaces for caries prevention. The temperature changes in the pulpal chamber was firstly evaluated in vitro to determine safe energy irradiation conditions range. The purpose of this work is to verify the occurrence of pulp inflammation under those irradiation conditions in rabbits. Ten rabbits (NZB) were divided in 5 groups according to the sacrifice period (control, immediately after irradiation, 6, 24 and 72 hours after irradiation). The rabbits posterior upper region teeth of each animal were irradiated with 10 pulses of a Ho:YLF prototype operating at 0.5 Hz and 300m)/pulse on the left side and 500m) on the right side. Sacrifices were obtained through transcardiac perfusion and the samples were prepared for pathological analysis. The in vitro temperature monitoring revealed an increase of 1°C to the 300m) energy and 4.5°C for the 500m) energy. SEM observations showed the occurrence of melting and resolidification. From the in vivo analysis it can be concluded that there was low degree of inflammation for the highest energy used and no pulpal alterations for the lowest one.Resumo IPEN-doc 08038 An alternative procedure for laser irradiation in endodontical therapy2000 - BACHMANN, L.; STREFEZZA, C.; ZEZELL, D.M.; EDUARDO, C.P.Artigo IPEN-doc 07131 Thermal effects during in vitro intracanal application of Nd:YAG laser2000 - STREFEZZA, C.; ZEZELL, D.M.; BACHMANN, L.; CECCHINI, S.C.; PINOTTI, M.; EDUARDO, C.P.Artigo IPEN-doc 13873 Monitoracao de temperatura na camara pulpar durante irradiacao com laser de Ho:YLF na superficie de esmalte de dente de coelho2001 - STREFEZZA, CLAUDIA; GROTH, EDUARDO de B.; BACHMANN, LUCIANO; ZEZELL, DENISE M.
