objective: microleakage in the gingival floor of class ii composite restorations can compromise the marginal adaptation of the filling material to the cavity edges. the aim of this study was to evaluate the effect of light conducting cylindrical inserts in decreasing the microleakage of the gingival floor in cavities 1mm below the cej. materials and methods: eighty maxillary first molars were r...

introduction: although composite resins have improved greatly since their introduction, microleakage is one of the most frequently encountered problems. this study compared the effects of different monomer systems and layering techniques on the bacterial leakage of cl i composite resin restorations. methods: eighty-two sound human third molars were used. the teeth were randomly divided into six...

the anterior maxilla presents a challenging milieu interior for ideal placement of implants because of the compromised bone quality. with the advent of intraoral bone harvesting and augmentation techniques, immediate implant placement into fresh extraction sockets have become more predictable. immediate implant placement has numerous advantages compared to the delayed procedure including superi...
