“… 2 7 Accurate radiographic localization of the tooth is a prerequisite for both an initial extraction and the extraction of a displaced tooth. 15 The preoperative assessment should include a detailed morphologic analysis of the third molar and its relationship to adjacent structures and surrounding tissues. 16 The identification of predictive variables associated with adverse events may be helpful in reducing complications.…”

PurposeThis study investigated maxillary third molars and their relation to the maxillary sinus using panoramic radiography and cone-beam computed tomography (CBCT).Materials and MethodsA total of 395 maxillary third molars in 234 patients were examined using panoramic radiographs and CBCT images. We examined the eruption level of the maxillary third molars, the available retromolar space, the angulation, the relationship to the second molars, the number of roots, and the relationship between the roots and the sinus.ResultsFemales had a higher frequency of maxillary third molars with occlusal planes apical to the cervical line of the second molar (Level C) than males. All third molars with insufficient retromolar space were Level C. The most common angulation was vertical, followed by buccoangular. Almost all of the Level C molars were in contact with the roots of the second molar. Erupted teeth most commonly had three roots, and completely impacted teeth most commonly had one root. The superimposition of one third of the root and the sinus floor was most commonly associated with the sinus floor being located on the buccal side of the root.ConclusionEruption levels were differently distributed according to gender. A statistically significant association was found between the eruption level and the available retromolar space. When panoramic radiographs showed a superimposition of the roots and the sinus floor, expansion of the sinus to the buccal side of the root was generally observed in CBCT images.

“…Nevertheless, the tooth displacement to lateral pharyngeal space is not common, occurring in few cases [2,3,[9][10][11][12]. In the present case report, we believe that the absence of the lingual portion of cortical bone, which occurs in the contralateral side, facilitated the dental displacement when combined with the direct trauma.…”

The removal of displaced dental elements from deep anatomical spaces is a condition that requires the knowledge of the region and skills to perform the procedure. The lateral pharyngeal space contains important structures such as the internal carotid artery and close proximity with the cranium basis. The aim of this paper is to report a clinical case of a lower third molar displaced to the lateral pharyngeal space after a mandibular angle fracture and its treatment by surgical intervention. The tooth was removed under general anesthesia by direct approach and the fracture was reduced and fixed with a plate and screws. This case report illustrates the importance of an immediate procedure to avoiding severe complications and further damage to important anatomical structures.

“…It should also be extended with the necessary radiological diagnostics to assess possible difficulties resulting from the position of the retained tooth and its relation to the lower alveolar nerve canal and adjacent teeth in the aspect of possible complications. In some cases, in addition to the pantomographic X-ray, it is advisable to perform a CBCT examination, which additionally presents the projection of the retained tooth in three dimensions [7]. It allows the assessment of the position er into the anatomical structures and impede its subsequent extraction [6].…”

“…It allows the assessment of the position er into the anatomical structures and impede its subsequent extraction [6]. Postponing surgery can often lead to the formation of an abscess and cause not only local complications like pain, swelling, lock-jaw, or dysphagia but also general inflammatory reaction [3,7,9]. Kose et al [6] suggest removal of the dislocated tooth as soon as it is possible.…”

Iatrogenic dislocation of the lower wisdom tooth to the bottom of the oral cavity and neck is a rare complication that may occur during surgical extraction, usually causing inflammation and abscesses, and therefore it requires specialist treatment in a hospital in the Department of Maxillo-Facial Surgery. The case described in this paper required surgical removal of the displaced tooth and evacuation of the abscess from the extraoral approach. The patient had uneventful perioperative course, no postoperative complications were observed, and the healing proceeded in a normal way. During three outpatient follow-ups carried out at intervals of one month, no abnormalities in healing were found.
