to report the effect of oroantral communication OAC on the prognosis of apicectomy of maxillary canine, premolars, and molars and its effect on the sinus status.

n (patients): 276 Patients. n (teeth): 314, OAC in 13% of the teeth (41 teeth)

Materials and Methods:

 – Surgery was done in conventional; way retrograde filing was silver amalgam in 133 teeth, GP 11 teeth, and Cavit in 8 teeth.

F/U period varied between 6 months and 12 years.

26 Pts with OAC were exposed to tomography


Successful, when the apical area showed complete bone regeneration ± periodontal membrane; Uncertain, when at certain degree of bone regeneration had occurred but a radiolucency was still demonstrable; Unsuccessful, when there was no bone regeneration or an increased radiolucency and/or demonstrable resorption of the root and/or presence of S&S uncertain was used at the 6-month follow-up even when the radiographic status was unchanged.

The status of maxillary sinus was based on the fluid level, bone defect, and hyperplasia. If the mucosal hyperplasia was less than 5 mm thick it was considered moderate if it was thicker it was severe.

Most Highlighted Results: ⁻Success with OAC 75% Success without OAC 80%

Clinical Significance:

Cases with OAC would have similar results to cases with no communications
