The following should be considered prior to carrying out any dental treatment:
Size of the antrum and proximity to teeth – this can be assessed radiographically
Shape and size of teeth and roots – this can be assessed radiographically
Presence of periapical pathology – this can be assessed radiographically
The age of the patient
The patient’s past dental historyIf the above factors are assessed as increasing the risk of OAC development, the clinician should take appropriate steps to carefully remove the tooth in question, possibly carrying out a surgical extraction and in an appropriate setting. Hence, in such cases:

Avoid using too much of apical pressure during tooth extraction
Perform surgical extraction with roots sectioning
Consider referral to OMFS at local hospital

Treatment
The primary aim of treatment of a newly formed oroantral communication is to prevent the development of an oroantral fistula as well as chronic sinusitis. The decision on how to treat OAC/OAF depends on various factors. Small size communications between 1 and 2 mm in diameter, if uninfected, are likely to form a clot and heal by itself later. Communications larger than this require treatments to close the defect and these interventions can be categorised into 3 types: surgical, non-surgical and pharmacological. Surgery
Surgical methods are required if a large defect is present or if a defect persists. Surgery involves creating a flap utilising local tissue to close the communication. There are a number of different flaps that can be used such as the buccal advancement flap, the buccal fat pad flap, a combination of the two and a palatal flap.
Instead it concluded that "The paucity of evidence related to early versus delayed surgery is of particular concern, as patients and providers must decide whether to attempt initial nonoperative management or proceed immediately with surgical repair". In terms of operative techniques, differences in neither cuff integrity nor shoulder function were reported in studies comparing single-row versus double-row suture anchor fixation and mattress locking versus absorbable sutures. Postoperatively, a slight advantage was evident in patients who performed continuous passive motion alongside physical therapy, as opposed to those who solely performed physical therapy. There is insufficient evidence to adequately compare the effects of operative against nonoperative interventions. Complications were reported very seldom, or were not determined to be clinically significant.A 2016 study evaluating the effectiveness of arthroscopic treatment of rotator cuff calcification firmly supported surgical intervention. Calcification of the supraspinatus tendon is a major contributor to shoulder pain in the general population and is often worsened following a supraspinatus tear. The results of the study included the return to sports and original functionality of 95.8% of the patients after a mean of 5.3 post-operative months. A significant decrease in pain was observed over time following removal of the calcification. The study showed the overall effectiveness of arthroscopic procedures on shoulder repair, and the lack of risk experienced. Before surgery, supraspinatus tendonitis should be ruled out as the cause of pain. Additional images
