Intentional oroantral communications were established in 5 Macaca fascicularis monkeys by forcing root canal instruments through the palatal root canal of the maxillary second molar. Calcium hydroxide was then injected into the maxillary sinus cavity. Postoperative inflammatory changes of the ipsilateral sinus cavity were noted by both clinical (at autopsy) and histologic examination at 8, 12 and 16–week intervals. Following radiographic examinations, the periodic identical projection technique was used prior to insertion of the calcium hydroxide, immediately after, and at the time the animals were sacrificed.
