The influence of facial types on the morphology and location of the greater palatine foramen: a CBCT study.

Objective: This study aimed to assess the morphology and location of the great palatine foramen (GPF) of different facial types using cone beam computed tomography (CBCT) scans.

Methods: Sixty CBCT scans were divided into: brachyfacial (n = 20), dolichofacial (n = 20) and mesofacial (n = 20) using Ricketts' VERT index for the determination of cephalometric facial type and imported into ImageJ software. GPF shape was characterized as: round, elongated in the anteroposterior direction (EAP), or elongated in the latero-medial direction (ELM).

Signs of the proximity of third molar roots to the mandibular canal: an observational study in panoramic radiographs.

The objectives of this study were to assess the relationship between mandibular third molars and the mandibular canal, establishing which radiographic signs are most prevalent in predicting contact between these structures, and to associate these signs and the proximity with the position of the third molar according to the classifications of Pell & Gregory and Winter. A retrospective, cross-sectional observational study was carried out on panoramic radiographs. From a dataset of 3289 images, a convenience sample of 1548 panoramic radiographs with a total of 2639 third molars was selected for evaluation.

Correction of Vertical Smile Discrepancy through Ceramic Laminate Veneers and Surgical Crown Lengthening.

In cases where malocclusion is associated with intrinsic discoloration and/or discrepancies in tooth size and shape, such as peg-shaped laterals, orthodontics alone may not improve the aesthetics. In these situations, veneers may be considered as an adjunct to orthodontic treatment to improve the overall aesthetics. The aim of this study is to report a clinical case where an uneven occlusal plane was corrected, and the positioning of gingival zeniths, color, shape, and size of the dental elements involved were improved by means of gingivectomy and rehabilitation with 10 ceramic laminate veneers.

Intraosseous Mucoepidermoid Carcinoma in the Mandible.

Although it is a rare neoplasm, intraosseous mucoepidermoid carcinoma is the most common and well-recognized intraosseous salivary gland tumor. Usually, it presents as an asymptomatic volume increase and most patients perceive the presence of the lesion within a year or less of evolution. They are more common in middle-aged adults and have a slight female predilection.

Approach and Treatment of Giant Luminal Unicystic Ameloblastoma.

Unicystic ameloblastoma is an odontogenic tumor that affects mainly young patients and usually involves the posterior region of the mandible. In this article, we report on the case a 12-year-old girl presenting with an 8-month history of facial swelling in her lower right quadrant. Radiographic examination revealed a unilocular radiolucent lesion extending from the body of the mandible through to the angle and ascending ramus.
