The Odontogenic Keratocyst in BCNS and Non-Syndrome Patients

As far as odontogenic keratocysts are concerned, it is not easy to envisage such stimuli as ultraviolet radiation or physical trauma to either mucosal basal epithelium or to odontogenic rests. Furthermore, although inflammation is commonly supposed to be the stimulus to proliferation in other odontogenic cysts, keratocysts, both syndrome and non-syndrome, often lack inflammation in their walls.12 However, it could be pertinent that these epithelia are subject to dental diagnostic X-rays, to “normal” masticatory and other physiological forces, to iatrogenic forces during dental treatment, and to tooth eruptive forces; these last in particular may be increased when eruption is impeded (i.e., in tooth impaction). There would seem to be scope here for a number of research projects; for example, is there a correlation between odontogenic keratocyst formation and tooth impaction, and can cultured mucosal and odontogenic epithelium from patients with odontogenic keratocysts be more easily induced to proliferate by such stimuli as we have alluded to than similar epithelium from non-keratocyst patients?

The CBCT images of 53 individuals (28 males and 25 females) with CL/P (40 unilateral and 13 bilateral patients) were obtained at the Faculty of Dentistry, Inonü University, Malatya, Turkey. For comparison, we evaluated a control group of 76 randomly selected patients (42 males and 34 females) in the same age range as the CL/P group for whom CBCT was performed for any other reason, including tooth impaction, temporomandibular joint problems, and a bone pathology, etc. We retrospectively evaluated 258 temporal bone images from 129 patients in terms of the morphological characteristics of the SSCC. This study was performed according to the principles of the Helsinki Declaration; all study subjects signed informed consent forms.

Calcifying epithelial odontogenic tumor (CEOT), also known as Pindborg tumor, was described by Danish oral pathologist Jens Pindborg in 1955 [1]. This benign odontogenic neoplasm is slow growing and expansile. Among all types of odontogenic tumors, CEOT accounts for only 1% of cases [2,3]. Primarily intraosseous, the tumor typically occurs in the posterior mandible, with over half of the described cases being associated with tooth impaction [1,4,5] and most patients being asymptomatic. An extraosseous variant, usually found in the anterior gingiva, has also been reported [6].
Incidence of impacted teeth requiring fenestration, traction, and orthodontic treatment in Japan

These included tooth impaction due to odontoma, impacted teeth associated with follicular dental cysts, horizontal impaction of all four maxillary anterior teeth, palatal impaction of the canine, inverse impaction of the central incisors, and impacted mandibular second molars below impacted mandibular third molars.
