Extraction might be contraindicated and might be simple or surgical, often depending on the location of the teeth. In some cases, for aesthetic purposes, a surgeon may wish to expose the canine. This may be achieved through open or closed exposure. Studies show no advantage of one method over another. Laser can be used to uncover superficially impacted teeth with no bleeding and quick recovery

Bleb or bulla
The most common disease causing blebs or bullae is paraseptal emphysema though centrilobular emphysema may sometimes be involved. Other conditions associated with lung bullae are:
Other conditions associated with lung bullae are:

Alpha 1-antitrypsin deficiency
Marfan syndrome
Ehlers–Danlos syndromes
Cocaine smoking
Sarcoidosis
HIV/AIDS
Intravenous substance abuse

Cyst
A pulmonary cyst is not necessarily the same type of cyst seen in many cystic lung diseases. The cyst for example in pneumocystis pneumonia is not the same as the pulmonary cyst. Cystic lung diseases include:

Langerhans cell histiocytosis (LCH)
Lymphangioleiomyomatosis (LAM)
Lymphocytic interstitial pneumonia (LIP)
Birt–Hogg–Dubé syndrome
Pneumocystis pneumonia
Pulmonary amyloidosis
Light chain deposition disease
Lung metastases rarely cause multiple cystic lung lesions. This form of presentation has been described in metastatic sarcomas. Incidental blebs and cysts
A focal lung pneumatosis that is an incidental imaging finding such as on a CT scan, without suspicious findings (such as findings indicating any of the diseases listed above), generally does not indicate further follow-up. Cavity

Two infectious diseases that are commonly associated with cavities of lung tissue are Mycobacterium tuberculosis and Klebsiella pneumoniae. The formation of cavities is due to tissue necrosis and creates an environment that allows the pathogen to expand in numbers and spread further.In the absence of infectious symptoms, a lung nodule with cavitation is a suspected lung cancer. == References ==
