The of this study was to evaluate the bonding strength of a
posterior composite restorations when two different types of
equipment methods were used for preparation of dentin (Erbium-doped
yttrium aluminum garnet laser (Er:YAG ) and diamond burs).
This study specimen consisted of Eighty molars, was divided
randomly into two main groups (40 molars were prepared with
diamond burs, and 40 molars were prepared with laser Er: YAG).
Recently laser applications have been expanding to include many fields.
Among these, are medical laser surgery and biological applications. It is
important to understand the interaction mechanisms that may occur when
applying laser light to biolog
ical tissues in order to minimize damage to the
tissues resulting from extra heat applied. The aim of this study is to study the
temperature distribution in living biological tissues when laser irradiation is
used in a treatment by solving bio-heat equation.
