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 aimed to investigate the relationship between the maximum standardized uptake value (SUVmax) of alveolar bone and lymph nodes (LNs) in the neck using 18F-FDG PET scans in patients with and without odontogenic inflammation.
  • Significant differences in SUVmax values were found for level IB and IIA LNs between the two patient groups, indicating that inflammation affects these lymph nodes more than others.
  • The research concluded that higher SUVmax values in level IB and IIA LNs are linked to increased SUVmax values in alveolar bone, suggesting a connection between dental inflammation and lymphatic response.

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.

Background: Very recently, a significant relationship between tonsilloliths and dental plaque-related pathologies was reported using digital panoramic radiographs. Their dynamics over time suggest that tonsilloliths may be in a permanently active phase that functions to remove foreign matter. The aim of the study was to evaluate the relationship between the occurrence of tonsilloliths and the extent of periodontitis.
