“…For this reason, the chisquared test was estimated for both the types of SB (II and III) due to the irrelevant number of patients with type III SB. The chisquared statistic confirmed that there is no statistically significant association between the PP and types II and III SB (p > 0.05) as confirmed in literature (23,47).…”

Background: The ponticulus posticus (PP) is an important anomaly of the atlas (C1 vertebra) with a complete or partial bone bridge that transforms the groove of the vertebral artery (VA) into a canal (arcuate foramen). The aim was to retrospectively determine prevalence of PP evaluating morphological features and the possible association with other dentoskeletal anomalies in the midface and neck area such as maxillary canine impaction (MCI), atlas posterior arch deficiency (APAD), and sella turcica bridging (SB).Methods: This study was conducted in the Department of Medical, Oral and Biotechnological Sciences of the University “G. D'Annunzio” in Chieti. The detection of PP was performed on 500 patients with cone beam CT (CBCT) images (6 to 87 years).Results: Analysis revealed the presence of uni- and bi-lateral PP in 110 patients (22%): 24 (4.8%) patients with bilateral complete PP, 12 (2.4%) patients with complete PP on the left, 6 (1.2%) patients with complete PP on the right, 8 (1.6%) patients with complete PP on the right and partial PP on the left, 6 (1.2%) patients with complete PP on the left and partial PP on the right, 26 (5.2%) patients with partial bilateral PP, 18 (3.6%) patients with partial left PP, and 10 (2%) patients with partial PP on the right. The Chi-squared statistic confirmed that there are significant associations between MCI and PP (p = 0.020) and between SB and MCI (p <0.00001). No correlation between chronological age and presence of the PP (p = 0.982), between chronological age and morphotypes of the PP (p = 0.779), between APAD and the PP (p = 0.0757), between SB and the PP (p = 0.111), and between APAD and MCI (p = 0.222) were found.Conclusion: This observational study showed how bilateral partial variant and bilateral complete variant are the most represented morphotypes in all the age groups. The prevalence of MCI is positively associated with PP and with SB.

Introduction: Researchers have been interested in the relationship between sella turcica bridging and various dental anomalies. This study investigates the association of sella turcica bridging and morphologic characteristics with the palatally impacted canine tooth.Materials and Methods: Orthodontic records with high-quality lateral cephalometric and panoramic images were chosen. The study comprised 30 patients with palatally impacted canines (17 females and 13 males) and 30 controls with erupted canines (15 males and 15 females). The measurements were performed using the SCANORA 5.2.6 software. Further, the relevant data was collected and analyzed using SPSS software version 22. Descriptive statistical analysis was used to investigate data after their validation, with t-tests and chi-square tests to compare the two groups. The regression test was used to lessen the effects of confounding variables.Results: In the study group, 5 patients had type III sella turcica bridging, whereas 2 patients in the control group had type III sella turcica bridging. Results showed a statistically significant difference between the two groups (P-value=0.017). In the study group, the interclinoid distance and canine tooth angle were significantly lower than the control group (P-value=0.001, P-value=0.001). However, there were no significant differences in the depth and anterior-posterior diameter of sella turcica between the two groups (P-value=0.543, P-value=0.766). In terms of age (P-value = 0.400) and gender (P-value = 0.605), there was no significant difference between the two groups.Conclusions: The palatally canine impaction may be associated with the bridging of the sella turcica. Therefore, sella turcica bridging can be used as a diagnostic parameter for palatally canine impaction.

“…Possible limitations of this systematic review result from a lack of standards for keywords in scientific papers. The use of a combination of subject headings, MeSH terms and free-text terms: “sella turcica” AND (“dental abnormalities” OR “dental anomalies” OR “malocclusion”), makes it impossible to find scientific papers with very detailed multi-word keywords, such as Dadgar et al 2020 [ 32 ] (“Palatally displaced impacted maxillary canines”, “Skeletal anomalies and normal variants”, “Sella turcica bridging”, “Atlas ponticulus posticus (arcuate foramen; sagittal foramen))” or Wak et al 2018 [ 33 ], with the following keywords: “Sella turcica bridging”, “Palatal impacted canine”, “CBCT”. In our opinion, the use of multi-word keywords is a serious obstacle in finding scientific papers to be cited and thus should be discouraged by editors in authors’ instructions.…”

Background: The sella turcica is a saddle-like structure in the middle cranial fossa on the intracranial surface of the sphenoid bone, visible on lateral cephalograms routinely conducted for orthodontic diagnosis. The development of facial structures follows similar traits to the sella turcica: glandular anomalies may be associated with functional disorders, e.g., altered hormonal levels, thus influencing dental development. The aim of this study is to find out if there is any association between the morphology of the sella turcica on cephalometric radiographs and the presence of dental abnormalities. (2) Methods: The search was conducted on 27 January 2021 in four search engines: Medline (PubMed Central), Scopus, Web of Science, Embase. The keywords used in the search strategy were as follows: “sella turcica” AND (“dental abnormalities” OR “dental anomalies” OR “malocclusion”). Since all the studies finally included were retrospective case–control studies, the Newcastle–Ottawa Quality Assessment Form for Case–Control Studies was applied. (3) Results: The search strategy identified 465 articles: 289 from PubMed, 121 from Scopus, 32 from Web of Science and 23 from Embase. Finally, 10 full-text papers were included into qualitative analysis. (4) Conclusions: Sella turcica bridging is very frequent among orthodontic patients. A clear association exists between dental abnormalities and sella turcica bridging.
