What exactly is an odontogenic cyst? How does it silently erode your teeth?
Odontogenic cyst, also known as apical cyst, is the most common odontogenic cyst. It may develop rapidly from untreated chronic apical periodontitis and result from pulp necrosis. This lesion usually forms around the root tips of the teeth and may grow silently without any obvious symptoms. Its lining is derived from epithelial remnants of Marasse cells, which proliferate to form cysts. Although most of the time odontogenic cysts do not cause significant pain, as the cysts grow and possibly become secondary infected, they may cause serious damage to the surrounding teeth and bone.
Odontogenic cysts often develop painlessly, but by the time they begin to cause pain, irreversible damage has usually already occurred.
Symptoms and Signs
Odontogenic cysts are usually asymptomatic at first, but may later become swollen and painful. When infection occurs, the cyst may appear as a round, hard bump, and over time the body may absorb some of the cyst wall, leaving behind an ointment-like fluid that accumulates beneath the mucosa. When the pulp becomes inflamed or infected, it often affects the tooth, causing discoloration.
Causes of odontogenic cysts
Often, odontogenic cysts form in connection with root infections of teeth, usually due to untreated tooth decay, which allows bacteria to penetrate deep into the pulp of the tooth, causing infection. When the dental pulp dies, the epithelial remnants of the Malassai cells proliferate, releasing toxins, which in turn trigger an inflammatory response at the root apex.
The growth of cysts is usually related to the body's inflammatory response and changes in the physiological environment around it, and they can expand rapidly in a short period of time.
Detection and diagnosis of odontogenic cysts
The diagnosis of an odontogenic cyst usually requires consideration of whether the nerve of the tooth is dead. This can be confirmed on an X-ray, where the cyst will appear as a dark area around the tip of the tooth root. Traditional X-rays or 3D cone beam scanning can help doctors confirm the presence of a cyst.
Treatment methods
The effective treatment is to completely remove the infected tissue, including the epithelium of the cyst wall, otherwise the cyst may recur. For teeth that have not had successful root treatment, root canal treatment should be performed to remove the necrotic pulp and properly seal it. If the tooth requires surgical treatment, a cystectomy or cystostomy may be considered.
EpidemiologyThe balance between public and private interests is an important issue facing dental care. Early detection and treatment of odontogenic cysts can effectively reduce the impact on patients.
Radicular cysts account for approximately 75% of cysts in the oral area, with a male to female ratio of approximately 3:2, and usually occur in the age group of 20 to 60 years old.
Odontogenic cysts occur worldwide, so understanding their characteristics and prevention strategies is essential to maintaining oral health. With advances in medical technology, we can identify and treat this problem earlier, but for the general public, are you ready to learn more about the potential risks and prevention methods of odontogenic cysts?
