Nasolabial Cyst: A Case Report with Ultrasonography and Magnetic Resonance Imaging Findings.

Nasolabial cysts are uncommon nonodontogenic lesions that occur in the nasal alar region. These lesions usually present with asymptomatic swelling but can cause pain if infected. In this case report, we describe the inadequacy of conventional radiography in a nasolabial cyst case, as well as the magnetic resonance imaging (MRI) and ultrasonography (US) findings in a 54-year-old female patient.

Correlation Between Tinnitus and Petrotympanic Fissure Status Among Patients With Temporomandibular Joint Dysfunction.

Purpose: The objective of this study was to evaluate the correlation between tinnitus and petrotympanic fissure (PTF) subtypes in patients diagnosed with temporomandibular joint dysfunction (TMD).

Materials And Methods: One hundred patients with TMD (50 with tinnitus, 50 without tinnitus) were evaluated retrospectively using cone-beam computed tomography (CBCT). CBCT images were analyzed according to PTF subtype diagnosis (types 1 to 3).

Evaluation of the morphological changes in the mandible for dentate and totally edentate elderly population using cone-beam computed tomography.

Purpose: The loss of teeth considerably modifies the mandibular shape. The aim of this study was to compare the morphological changes in the mandible for dentate and totally edentate elderly subjects using cone-beam computed tomography.

Methods: In total, 50 cone-beam computed tomography patients (25 dentate, 25 edentate) without any maxilla-mandibular dysmorphosis were analyzed retrospectively.

Mucoepidermoid carcinoma in a minor salivary gland in a child.

Mucoepidermoid carcinoma (MEC), one of the most common salivary gland malignancies, is rare in children. MEC mainly occurs in the parotid gland, along with minor glands being the second common site, particularly in palate. Clinical, histological, and radiological findings of palatal MEC in a 12-year-old girl are presented with three-year follow-up.

Do children with Wilson's disease have distinct craniofacial morphology? A cephalometric study.

Objectives: Patients with Wilson's disease (WD) develop osseous changes such as osteoporosis, spontaneous fractures, areas of sclerosis and demineralization of maxillary and mandibular bones, and neurologic symptoms including swallowing dysfunctions, which may affect dento-facial growth. However, dento-maxillo-facial structures of these patients have never been investigated. The present study aimed to discover if subjects with WD have different dentofacial structures.

The effect of right or left handedness on caries experience and oral hygiene.

Background: There is an indisputable relationship between tooth decay and oral hygiene. Caries can only be prevented by keeping tooth decay at bay. In several prophylactic methods, brushing is the most important.

Relationship among Schneiderian membrane, Underwood's septa, and the maxillary sinus inferior border.

Background: Osseo-integrated implants are increasingly being used to restore functional dentition; however, in the posterior region, implant placement can be problematic because of inadequate bone height. In this condition, maxillary sinus floor elevation surgery has become the treatment of choice. The presence of anatomic variations within the maxillary sinus such as Underwood's septa and thin Schneiderian membrane decreases the success of the sinus floor elevation.

Aplasia and agenesis of the frontal sinus in Turkish individuals: a retrospective study using dental volumetric tomography.

Agenesis of the paranasal sinuses is an uncommon clinical condition that appears mainly in the frontal (12%) and maxillary (5-6%) sinuses; in some populations, it appears at a higher proportion. This study investigated the prevalence of agenesis of the frontal sinuses using dental volumetric tomography (DVT) in Turkish individuals. The frontal sinuses of 410 patients were examined by DVT scans in the coronal planes for evidence of the absence of the frontal sinuses.

Prevalence of the types of the petrotympanic fissure in the temporomandibular joint dysfunction.

Background: Petrotympanic fissure (PTF) is a fissure in the temporal bone that runs from the temporomandibular joint (TMJ) to the tympanic cavity (TC). In PTF, the discomallear ligament (DML) connects the malleus in the tympanic cavity and the articular disc and capsule of the temporomandibular joint. PTF with the DML is a possible cause of aural symptoms related to temporomandibular joint dysfunction (TMD).

The mandibular angle in osteoporotic men.

Objectives: Osteoporosis induces the reduction of bone mass and screening for low bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) has been the current gold standard test to determine osteoporosis. Panoramic radiography is widely used in dentistry for routine examination of jaws. The objective of this study was to determine the relationship between the mandibular angle (MA) values and the vertebral bone mineral density (v-BMD) in 20 osteoporotic men.

A retrospective analysis of sphenoid sinus hypoplasia and agenesis using dental volumetric CT in Turkish individuals.

Purpose: In adults, sphenoid sinus agenesis is an extremely rare anomaly. The objective of this study was to investigate the prevalence of sphenoid sinus hypoplasia and agenesis using dental volumetric computed tomography (DVCT) in a population of Turkish individuals.

Materials And Methods: DVCT scans in the axial, coronal and sagittal planes of the sphenoid sinus of 384 patients were examined for evidence of sphenoid sinus agenesis and hypoplasia.

No correlation between mandibular and non-mandibular measurements in osteoporotic men.

Background: Screening for low bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) has been the traditional method for determining osteoporosis. Panoramic radiography is widely used in dentistry.

Purpose: To determine the relationships between the values of dental panoramic indices (the mental index (MI), antegonial index (AI), panoramic mandibular index (PMI)) and the values of skeletal BMD (femoral BMD (f-BMD), and vertebral BMD (v-BMD)) in 25 osteoporotic men.

Oral pemphigus vulgaris: a case report with review of the literature.

Pemphigus vulgaris is a chronic autoimmune mucocutaneous disease that initially manifests in the form of intraoral lesions, which spread to other mucous membranes and the skin. The etiology of pemphigus vulgaris is still unknown, although the disease has attracted considerable interest. The pemphigus group of diseases is characterized by the production of autoantibodies against intercellular substances and is thus classified as autoimmune diseases.

Keratocystic odontogenic tumor invading the right maxillary sinus: a case report.

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw. Involvement of the maxillary sinus is an unusual presentation. We present the case of a 23-year-old man with extensive KCOT and impacted third molar in the right maxillary sinus.

A dentigerous cyst containing an ectopic canine tooth below the floor of the maxillary sinus: a case report.

Ectopic eruption into the dental environment is common, whereas eruption into other sites is rare. Diverse anatomical locations such as the mandibular condyle, coronoid process, palate, maxillary sinuses and nasal cavity can infrequently be the site of ectopic tooth eruption. One of the nondental sites for ectopic eruption is the maxillary sinus.

Florid cemento-osseous dysplasia: a case report.

Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissues and involve, essentially, the same pathological process. They are usually classified, depending on their extent and radiographic appearances, into three main groups: periapical (surrounds the periapical region of teeth and are bilateral), florid (sclerotic symmetrical masses) and focal (single lesion) cemental dysplasias. Florid cemento-osseous dysplasia clearly appears to be a form of bone and cemental dysplasia that is limited to jaws.
