“…Additionally, we had a Ds individuals group in our study for which we evaluated common eruption disturbances (n = 213/338-63%) associated with this syndrome, which had a major influence on our 338 impacted or delayed/unerupted teeth [5,7,19,20]. According to the literature, GC absence or anatomical deformation could be possibly associated with various obstructive odontogenic tumors, such as compound or complex odontomas, mesiodens, or adenomatoid odontogenic tumors, which is demonstrated in our results [21][22][23][24][25][26][27][28][29][30][31].…”

“…The main reason why this sample was selected was that individuals with this genetic disorder may present various oral cavity alterations and specific oral/craniofacial characteristics such as class III malocclusions, maxillary hypoplasia, periodontal disease, dental caries, missing teeth, and some dental abnormalities such as microdontia, taurodontism, impacted teeth or hypodontia, and tongue disorders such as macroglossia that will affect their oral and respiratory functions, decreasing their oral quality of life [15][16][17][18]. Furthermore, due to these oral cavity alterations and Ds craniofacial characteristics, some parafunctional habits can be seen in these individuals such as tongue thrusting, bruxism, mouth breathing, and obstructive sleep apnea [25][26][27][28].…”

Background: The gubernacular canal (GC) is an important dental structure that enables the alveolar bone ridge cohesion of permanent teeth, although GC absence may indicate a dental eruption that might be associated with certain syndromes such as Down’s syndrome. This study aims to correlate the eruptive delay of permanent teeth in individuals with Down’s syndrome (Ds) and the gubernacular canal (GC) through cone-beam computed tomography (CBCT). Methods and Results: This cross-sectional study was conducted between January and July 2022 with a total of 31 individuals (G1 = 16 nonsyndromic and G2 = 15 Down’s syndrome) who went through imaging evaluation using CBCT with the following acquisition parameters: tube voltage of 95 kVp, tube current of 7 mA, exposure time of 5.9 s and voxel sizes and field of view 0.15 mm and 0.30 mm, respectively. The imaging evaluation was to assess whether all teeth analyzed had the presence of GC and/or teeth eruption disturbance, with a descriptive statistical analysis of relative frequencies and quantitative variables as well as the p-value (p < 0.005) by G Test. Results: A total of 618 teeth among 31 individuals were analyzed, 475 (76.8%) GC were detected by CBCT in 23/31 patients and of these, 6 belonged to G2. G2 had a decreased GC detection rate (n = 180–37.9%) and the most common tooth with GC detected was the mandibular 1st molar (21 GC/25 teeth—84%) and the absence of GC was most frequently observed in impacted and delayed/unerupted teeth of Ds individuals. Conclusion: We concluded that GC absence was higher among Ds individuals, explaining the increased rates of unerupted or impacted teeth in Ds individuals.

“…The gubernacular canal or gubernacular tract is an alveolar bony canal that contains the gubernacular cord, a fibrous connective tissue containing peripheral nerves, blood, lymph vessels, and epithelial cells of the dental lamina. The canal, which connects the permanent tooth’s pericoronal follicular tissue (dental sac) to the alveolar crest and the overlying gum, is located relative to the palatal of the deciduous tooth ( 1 , 2 ). The gubernacular canal has been stated to have a potential effect on the normal growth of permanent teeth ( 3 , 4 ).…”

Background There have been few studies that have evaluated the imaging characteristics of the gubernacular canal. Additionally, it is important to understand the role of this structure and its relationship with tooth erupt. Therefore, the objective of this study was to investigate the association between gubernacular canal features and teeth eruption status on cone-beam computed tomography (CBCT) images. Material and Methods In this cross-sectional study, 150 CBCT images were obtained from patients referred to a maxillofacial radiology clinic in Babol, northern Iran, in 2021. Eruption status (normal, delayed, and impacted) and the presence of the gubernacular canal were recorded. If the gubernacular canal was detected, its opening site in the alveolar crest (buccal, lingual, and central) and its attachment site to the dental follicle (usual, unusual) were further assessed. Results Gubernacular canal was observed in 133 (88.7%) of the total 150 CBCT images. Also, 41 cases (27.3%) had impacted teeth. The detection rate of the gubernacular canal in the normal, delayed, and impacted eruption of teeth was 92.1% (n=93), 75.0% (n=6), and 82.9% (n=34), respectively ( p =0.135). Opening the gubernacular canal in the alveolar crest was not associated with teeth eruption status. Also, unusual attachment sites of the gubernacular canal to dental follicles were mostly seen in abnormal eruptions. Conclusions According to the findings, observing the presence of the gubernacular canal on CBCT may not help anticipate teeth eruption problems. Key words: Gubernacular canal, Cone-beam computed tomography, Tooth eruption.

“…Supernumerary teeth most commonly occur in the anterior part of the upper jaw, lying symmetrically on one or both sides of the jaw, followed by maxillary fourth molars, maxillary premolars and mandibular premolars, in descending order [1,2]. Clinically, supernumerary teeth, irrespective of a normal or deformed shape, may lead to difficulties in permanent teeth eruption, malocclusion, resorption of adjacent tooth roots and failure of orthodontic treatment.…”

Impacted supernumerary teeth are defined as the presence of one or more teeth in a patient's upper and lower jaws in addition to the normal number of teeth in the dental arch. It has an incidence rate of approximately 1%-14% and more frequently occurs in males than females, may be single or multiple, unilateral or bilateral, erupted or impacted. In this article, we describe the case of a patient with two supernumerary teeth between the roots of the mandibular second premolar and the first molar, which influenced the effectiveness of the first orthodontic treatment. The special anatomical position of the complex supernumerary teeth made tooth extraction challenging. Given the higher risk status of surgery, we implemented a novel tooth extracting technique for this patient. Thus, in this study, we describe a case of minimally invasive extraction of bilateral mandibular impacted supernumerary teeth using a digital 3D positioning guide plate.
