Objective Masticatory muscle tendon-aponeurosis hyperplasia (MMTAH) is a recently identified condition characterized by restricted mouth opening due to hyperplasia of the temporalis muscle tendon and masseter muscle aponeurosis. This study examines the treatment and clinical course of patients with MMTAH who underwent surgery at our hospital. Subjects and methods The study included 14 patients (four males and 10 females; mean age: 33.

Article Synopsis
  • The study aimed to analyze the imaging characteristics of the gubernaculum tract (GT) in patients with cleidocranial dysplasia (CCD) using computed tomography (CT).
  • It found a high detection rate of GTs for both unerupted permanent teeth (83.5%) and supernumerary teeth (83.1%), with no significant differences between the two.
  • The results suggest that a specific structure involving GTs and dental follicles may indicate that multiple teeth could originate from a single dental lamina, potentially leading to eruption failures.

Article Synopsis
  • The study focuses on the challenges dentists face in accurately diagnosing cemento-osseous dysplasia (COD), especially when it's related to embedded teeth, as there aren't many reports detailing its imaging characteristics in these cases.
  • Researchers analyzed radiographs and histological findings of 225 patients with COD, uncovering 15 cases in 13 asymptomatic patients that highlighted specific imaging features around embedded mandibular third molars.
  • The findings emphasize the need for dentists to recognize the distinct imaging traits of COD compared to other dental cysts or tumors to improve diagnosis and treatment approaches.

Article Synopsis
  • * A significant difference was found in the distribution of ducts between the two groups, with patients having ranula showing fewer instances of undetected ducts.
  • * Additionally, patients with ranula lacked a specific type of duct (Rivinius duct only), highlighting differences in drainage patterns compared to healthy subjects.

The eruption pathway from the dental follicle to the gingiva for permanent teeth is known as the gubernaculum tract (GT), a physiologic structure thought to play a role in tooth eruption. Cone beam computed tomography and multi-detector computed tomography have recently been used to visualize the GT, with the results indicating that this structure might be related to the normal eruption of teeth. By contrast, curved and/or constricted GTs may lead to abnormal tooth eruption.

Objectives: The shapes of gubernaculum tracts (GTs) in molars as accessional teeth remain unidentified. To elucidate imaging peculiarities of GTs in molars with aging on multidetector-row computed tomography (MDCT).

Material And Methods: This retrospective study was conducted using CT images, including maxillary and mandibular molars, with no abnormal findings from 239 patients.

Background: Tonsilloliths are related clinically to halitosis and tonsillar abscess. However, the dynamics of tonsilloliths over time are unknown. The aim of the study was to evaluate change in the characteristics of tonsilloliths in a time-dependent fashion by follow-up computed tomography (CT).
