Clinical presentation and differential diagnosis of nasolabial cyst. (1/7)
Nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst occurring inferior to the nasal alar region. The patient usually presents with a slowly enlarging asymptomatic swelling, typically without radiographic abnormalities. This paper documents the presentation and management of a 46-year-old woman with a nasolabial cyst. The histopathologic features, differential diagnosis, treatment and prognosis are discussed.

The objective of this study was to assess the prevalence of odontogenic cysts (OCs) in Sicily and evaluate their distribution during a 20-year period. A cross-sectional retrospective study was carried out in 1,310 cysts of the jaw diagnosed in 12,197 individuals, who consecutively attended the Odontostomatologic Clinic of Palermo from 1986 to 2005. 1,273 cysts were classified as odontogenic, whereas only 37 were non-odontogenic. In the former group, the most frequent lesions were radicular cysts (84.5%), followed by dentigerous OCs (11.4%). Inflammatory radicular cysts were observed more in male gender, younger age at diagnosis and anterior maxilla as site of presentation. Unlike dentigerous cysts, the frequency of radicular cysts decreased from 10.4% in 1986-1995 to about 8% in 1996-2005 (P < 0.0001). Inflammatory radicular cysts are the most represented group among OCs in our area with a higher prevalence than that reported in other countries. The decreasing epidemiologic trend with time could be attributed to the possible changes in individual oral health behavior. (+info)Nasopalatine duct cyst. (4/7)

OBJECTIVE: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. STUDY DESIGN: A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayis University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. RESULTS: The prevalence of odontogenic and nonodontogenic cysts was 3.51%; males were affected more frequently than females. There were 452 odontogenic cysts (98.5%) and seven nonodontogenic cysts (1.5%). The most frequent odontogenic cyst was radicular (54.7%), followed by dentigerous (26.6%), residual (13.7%), odontogenic keratocyst (3.3%), and lateral periodontal cyst (0.2%). Nasopalatine duct cyst (1.5%) was the only nonodontogenic cyst. By age, cysts peaked in the third decade (24.2%). Concerning location, no statistically significant difference was found between the maxilla and mandible (p>0.05). The most frequent radiological feature of these lesions was unilocular cyst (93.7%). Pathologies associated with cystic lesions occurred in 14.7%. CONCLUSION: The prevalence of both odontogenic and nonodontogenic cysts were lower than that reported in many other studies. In our study population, cysts were mainly inflammatory in origin. (+info)Morphological characterization of the nasopalatine region in human fetuses and its association to pathologies. (7/7)
(+info)Nonodontogenic cysts are a type of cyst that occur in the oral and maxillofacial region, but they do not originate from tooth-forming tissues. These cysts can develop in various locations within the jaws, including the bone or soft tissues. They are typically classified into several categories based on their origin, such as developmental, inflammatory, or neoplastic.
Examples of nonodontogenic cysts include:
1. Nasopalatine duct cyst - This is the most common type of nonodontogenic cyst and arises from remnants of the nasopalatine duct, which is a structure present during embryonic development. It typically appears in the anterior region of the maxilla (upper jaw).
2. Nasolabial cyst - This rare cyst develops near the nasolabial fold, between the nose and the upper lip. Its origin is unclear but may be related to embryonic remnants or developmental abnormalities.
3. Median mandibular cyst - Also known as a median mental cyst, this rare cyst forms in the midline of the mandible (lower jaw) and may originate from remnants of the dental lamina or other developmental structures.
4. Lateral periodontal cyst - This inflammatory cyst arises from the periodontal ligament, which supports the teeth within their sockets. It is usually found near the roots of lower molars and premolars.
5. Glandular odontogenic cyst - This developmental cyst originates from remnants of minor salivary glands or epithelial rests in the jawbone. It can appear as a unilocular (single-chambered) or multilocular (multi-chambered) cyst and may have a more aggressive behavior than other nonodontogenic cysts.
6. Dentigerous cyst - Although technically classified as an odontogenic cyst, the dentigerous cyst is sometimes considered a borderline case because it arises from the crowns of unerupted teeth rather than their roots. It can grow quite large and may cause significant bone resorption.
Nonodontogenic cysts are less common than odontogenic cysts, but they still require proper diagnosis and treatment to prevent complications such as tooth displacement, jaw deformation, or infection. Treatment options for nonodontogenic cysts depend on their size, location, and histological features and may include enucleation (complete removal), marsupialization (creating a communication between the cyst and oral cavity to allow for gradual reduction), or more extensive surgical procedures. Regular follow-up appointments with your dentist or oral surgeon are essential to monitor healing and ensure that the cyst does not recur.
Jaw diseases refer to a variety of conditions that affect the temporomandibular joint (TMJ) and the surrounding muscles, as well as dental disorders that can impact the jaw. Some common examples include:
1. Temporomandibular Joint Disorders (TMD): These are problems with the TMJ and the muscles that control jaw movement. Symptoms may include pain, clicking or popping sounds, and limited movement of the jaw.
2. Osteonecrosis of the Jaw: This is a condition where bone in the jaw dies due to lack of blood supply. It can be caused by radiation therapy, chemotherapy, or certain medications.
3. Dental Cavities: These are holes in the teeth caused by bacteria. If left untreated, they can cause pain, infection, and damage to the jawbone.
4. Periodontal Disease: This is an infection of the gums and bones that support the teeth. Advanced periodontal disease can lead to loss of teeth and damage to the jawbone.
5. Jaw Fractures: These are breaks in the jawbone, often caused by trauma.
6. Oral Cancer: This is a type of cancer that starts in the mouth or throat. If not treated early, it can spread to the jaw and other parts of the body.
7. Cysts and Tumors: These are abnormal growths in the jawbone or surrounding tissues. While some are benign (non-cancerous), others can be malignant (cancerous).
8. Osteomyelitis: This is an infection of the bone, often occurring in the lower jaw. It can cause pain, swelling, and fever.
9. Oral Thrush: This is a fungal infection that causes white patches on the inside of the mouth. If left untreated, it can spread to the jaw and other parts of the body.
10. Sinusitis: Inflammation of the sinuses can sometimes cause pain in the upper jaw.
A toothache is defined as pain or discomfort in or around a tooth, usually caused by dental cavities, gum disease, tooth fracture, or exposed tooth roots. The pain may be sharp and stabbing, throbbing, or constant and dull. It can also be aggravated by hot, cold, sweet, or sour foods and drinks, or by biting or chewing. Toothaches are serious and should not be ignored as they can be a sign of more significant dental issues that require immediate professional attention from a dentist.
Root canal therapy, also known as endodontic treatment, is a dental procedure that involves the removal of infected or damaged pulp tissue from within a tooth's root canal system. The root canal system is a series of narrow channels that run from the center of the tooth (pulp chamber) down to the tip of the tooth roots, containing nerves, blood vessels, and connective tissues.
During the procedure, the dentist or endodontist will gain access to the pulp chamber, carefully clean and shape the root canals using specialized instruments, and then fill and seal them with a rubber-like material called gutta-percha. This helps prevent reinfection and preserves the structural integrity of the tooth. In many cases, a crown or other restoration is placed over the treated tooth to protect it and restore its function and appearance.
Root canal therapy is typically recommended when the pulp tissue becomes inflamed or infected due to deep decay, repeated dental procedures, cracks, or chips in the teeth. The goal of this treatment is to alleviate pain, preserve natural tooth structure, and prevent the need for extraction.
Odontogenic cysts are a type of cyst that originates from the dental tissues or odontogenic apparatus. They are typically found in the jawbones, and can be classified as developmental or inflammatory in origin. Developmental odontogenic cysts arise from remnants of the tooth-forming structures, while inflammatory odontogenic cysts result from an infection or injury to a tooth.
The most common types of odontogenic cysts include:
1. Periapical cyst - an inflammatory cyst that forms at the tip of the root of a dead or non-vital tooth.
2. Dentigerous cyst - a developmental cyst that surrounds the crown of an unerupted or impacted tooth.
3. Follicular cyst - a type of dentigerous cyst that forms around the crown of an unerupted wisdom tooth.
4. Odontogenic keratocyst - a developmental cyst that arises from the dental lamina and has a high recurrence rate.
5. Lateral periodontal cyst - a rare, developmental cyst that forms in the periodontal ligament of a vital tooth.
Odontogenic cysts can cause various symptoms such as swelling, pain, or numbness in the affected area. They may also displace or resorb adjacent teeth. Diagnosis is typically made through radiographic imaging and histopathological examination of tissue samples obtained through biopsy. Treatment options include surgical excision, marsupialization (a procedure that creates an opening between the cyst and oral cavity), or enucleation (removal of the cyst lining).
A cyst is a closed sac, having a distinct membrane and division between the sac and its surrounding tissue, that contains fluid, air, or semisolid material. Cysts can occur in various parts of the body, including the skin, internal organs, and bones. They can be caused by various factors, such as infection, genetic predisposition, or blockage of a duct or gland. Some cysts may cause symptoms, such as pain or discomfort, while others may not cause any symptoms at all. Treatment for cysts depends on the type and location of the cyst, as well as whether it is causing any problems. Some cysts may go away on their own, while others may need to be drained or removed through a surgical procedure.
An Odontogenic Cyst, Calcifying is a specific type of cyst that originates from the dental tissues. It's also known as a calcifying odontogenic cyst or Gorlin cyst. This cyst is characterized by the presence of calcified structures within its lining.
The calcifications can appear as flecks or more complex structures, such as teeth-like formations. The lining of this cyst often contains ghost cells, which are the remains of epithelial cells that have undergone calcification.
These cysts are typically slow-growing and asymptomatic, although they can sometimes cause swelling or pain if they become large enough to compress adjacent tissues. They are most commonly found in the jaw bones, particularly the mandible.
While the exact cause of calcifying odontogenic cysts is not fully understood, they are thought to arise from developmental abnormalities in the tissues that form teeth. Treatment typically involves surgical removal of the cyst.
Odontogenic tumors are a group of neoplasms that originate from the dental tissues or their remnants, including the odontogenic epithelium, ectomesenchyme, and/or their derivatives. These tumors can be benign or malignant and may affect the jaw bones and surrounding structures. They can cause various symptoms, such as swelling, pain, loosening of teeth, and altered bite. The classification of odontogenic tumors includes a wide range of entities with different biological behaviors, clinical features, and treatment approaches. Accurate diagnosis is essential for proper management and prognosis.
Aneurysmal bone cyst (ABC) is a benign but locally aggressive tumor that typically involves the metaphysis of long bones in children and adolescents. It is characterized by blood-filled spaces or cysts separated by fibrous septa containing osteoclast-type giant cells, spindle cells, and capillary vessels.
ABCs can also arise in other locations such as the vertebral column, pelvis, and skull. They may cause bone pain, swelling, or pathologic fractures. The exact cause of ABC is unknown, but it is thought to be related to a reactive process to a primary bone lesion or trauma.
Treatment options for ABC include curettage and bone grafting, intralesional injection of corticosteroids or bone marrow aspirate, and adjuvant therapy with phenol or liquid nitrogen. In some cases, radiation therapy may be used, but it is generally avoided due to the risk of secondary malignancies. Recurrence rates after treatment range from 10-30%.
Maxillary diseases refer to conditions that affect the maxilla, which is the upper bone of the jaw. This bone plays an essential role in functions such as biting, chewing, and speaking, and also forms the upper part of the oral cavity, houses the upper teeth, and supports the nose and the eyes.
Maxillary diseases can be caused by various factors, including infections, trauma, tumors, congenital abnormalities, or systemic conditions. Some common maxillary diseases include:
1. Maxillary sinusitis: Inflammation of the maxillary sinuses, which are air-filled cavities located within the maxilla, can cause symptoms such as nasal congestion, facial pain, and headaches.
2. Periodontal disease: Infection and inflammation of the tissues surrounding the teeth, including the gums and the alveolar bone (which is part of the maxilla), can lead to tooth loss and other complications.
3. Maxillary fractures: Trauma to the face can result in fractures of the maxilla, which can cause pain, swelling, and difficulty breathing or speaking.
4. Maxillary cysts and tumors: Abnormal growths in the maxilla can be benign or malignant and may require surgical intervention.
5. Oral cancer: Cancerous lesions in the oral cavity, including the maxilla, can cause pain, swelling, and difficulty swallowing or speaking.
Treatment for maxillary diseases depends on the specific condition and its severity. Treatment options may include antibiotics, surgery, radiation therapy, or chemotherapy. Regular dental check-ups and good oral hygiene practices can help prevent many maxillary diseases.
Mandibular diseases refer to conditions that affect the mandible, or lower jawbone. These diseases can be classified as congenital (present at birth) or acquired (developing after birth). They can also be categorized based on the tissues involved, such as bone, muscle, or cartilage. Some examples of mandibular diseases include:
1. Mandibular fractures: These are breaks in the lower jawbone that can result from trauma or injury.
2. Osteomyelitis: This is an infection of the bone and surrounding tissues, which can affect the mandible.
3. Temporomandibular joint (TMJ) disorders: These are conditions that affect the joint that connects the jawbone to the skull, causing pain and limited movement.
4. Mandibular tumors: These are abnormal growths that can be benign or malignant, and can develop in any of the tissues of the mandible.
5. Osteonecrosis: This is a condition where the bone tissue dies due to lack of blood supply, which can affect the mandible.
6. Cleft lip and palate: This is a congenital deformity that affects the development of the face and mouth, including the lower jawbone.
7. Mandibular hypoplasia: This is a condition where the lower jawbone does not develop properly, leading to a small or recessed chin.
8. Developmental disorders: These are conditions that affect the growth and development of the mandible, such as condylar hyperplasia or hemifacial microsomia.
