What is the most common cause of a radicular cyst?
Radicular cysts generally originate after trauma or dental caries. Dental caries cause inflammation of the pulp cavity, leading to pulp necrosis [8]. The infection then spreads to the tooth apex of the root, causing periapical periodontitis, which leads to either an acute abscess or a chronic granuloma.
What is radicular cyst?
A radicular cyst is generally defined as a cyst arising from epithelial residues (cell rests of Malassez) in the periodontal ligament as a consequence of inflammation, usually following the death of the dental pulp.
Is periapical cyst same as radicular cyst?
Periapical cysts, also known as radicular cysts, are the most frequent cystic lesion related to teeth (see mandibular lesions) and result from infection of the tooth. On imaging, they generally appear as a round- or pear-shaped, unilocular, lucent lesion in the periapical region, usually measuring <1 cm.
Does radicular cyst cause root resorption?
Radicular cysts grow slowly and lead to mobility, root resorption and displacement of teeth. Once infected they may lead to pain and swelling and patients become aware of the problem.
What does a radicular cyst look like?
Radiographic features Most radicular cysts appear as round- or pear-shaped, unilocular, lucent lesions in the periapical region 3. They are usually <1 cm in diameter and are bordered by a thin rim of cortical bone. The associated tooth usually has a deep restoration or large carious lesion.
What causes a cyst under a tooth?
Periapical Cyst This cyst is caused by the death or necrosis of the pulp tissue inside the tooth. Death of the pulp is usually a result of tooth decay or injury. When pulpal necrosis occurs, it causes inflammation and the release of toxins, usually at the end of the root tip, hence the name “root end cyst”.
How does radicular cyst form?
Radicular cysts may account for up to as many as 70% of all cystic jawbone lesions. These cysts are thought to be the end results of epithelial cell rests proliferating during inflammation of teeth with infected and necrotic pulp, and apical periodontitis (inflammation of the gums).
What does the word radicular mean?
Definition of radicular 1 : of or relating to a plant radicle. 2 : of, relating to, or involving a nerve root radicular pain.
Is radicular cyst a true cyst?
Histologically, radicular cysts can be categorized into pocket and true cyst. The radicular cyst appears as an osteolytic periapical radiolucent lesion around the apex of an endodontically involved tooth on conventional radiography and cone beam computed tomography.
Are radicular cysts painful?
Such cysts are very common. Although initially asymptomatic, they are clinically significant because secondary infection can cause pain and damage. In radiographs, the cyst appears as a radiolucency (dark area) around the apex of a tooth’s root….

How are dental cysts diagnosed?
Since small cysts usually go unnoticed, their diagnosis may not be possible until you have a dental x-ray. A cyst may appear on the x-ray as a small spot. For further confirmation of a cyst, you may have to do a CT scan or an MRI scan.
What is radicular pulp?
Radicular pulp is that pulp extending from the cervical region of the crown to the root apex. They are not always straight but vary in shape , size and number. The radicular portion is continuous with the periapical tissues through the apical foramen or foramina.
Is radicular cyst painful?
Such cysts are very common. Although initially asymptomatic, they are clinically significant because secondary infection can cause pain and damage. In radiographs, the cyst appears as a radiolucency (dark area) around the apex of a tooth’s root.
Do antibiotics help a dental cyst?
Sometimes a minor dental cyst can be treated with a course of prescription antibiotics or anti-inflammatory medication. This can allow your body to naturally absorb the cyst without need of invasive treatment. A small dental cyst near the gumline or another minimally invasive location might be removed without sedation.
How are dental cysts treated?
There are two ways to treat a dental cyst: Surgery – for the removal of all types of cysts or tumours. Endodontic Therapy – This is done in conjunction with surgical removal if the cyst is associated with an infected root canal.
Are radicular cysts associated with primary teeth normal?
Radicular cysts associated with primary teeth are rare. This case report describes radicular cyst associated with carious primary mandibular second molar in a 5-year-old patient and discusses its surgical intervention, space management, and follow-up for 3½ years. Radicular cysts associated with primary teeth are rare.
How do you identify a radicular cyst?
A small size radicular cyst is difficult to identify as it is considered a normal dental follicle. When the crown and dental sac distance expands the normal limit it is known to be the primary sign of radicular cyst. X-ray and 3D cone beam images can be used to identify the cyst as well.
What causes a radicular cyst on the jaw?
The most common factor considered to cause a radicular cyst is caries. Traumatic injuries to the teeth can also result in the cyst of jaws. There was a steep rise in the cases of radicular cysts in the third decade. The frequency of radicular cyst in females is generally lower than in males.
Does pulp therapy increase the rate of growth of radicular cysts?
Radicular cysts arising from deciduous teeth are rare. This report presents a case of radicular cyst associated with a primary molar following pulp therapy and discusses the relationship between pulp therapy and the rapid growth of the cyst.
