Regarding the prevalence of the artery, there was a statistically significant difference between edentulous and dentulous alveolar crest where the artery was identified.
Following primary debridement AP flaws and alveolar crest deformities can be seen in patients with maxillary AP fractures.
Correlational statistics compared three variables (the length of the tongue stud, the diameter of the tongue stud ball, and the length of time that the tongue stud had been worn) to presence of osseous abnormalities inferior to the alveolar crest. Independent sample t-test statistics were conducted comparing the experimental group to the control group in relation to presence or absence of mobility, recession, periodontal pocketing, and broken teeth.

Using digital radiography technology (Computer-Assisted Radiographic Evaluation [C.A.R.E.] software, Kaiser RT 1 Fototechnik, San Antonio, Texas), two independent examiners enlarged and measured posterior interproximal mesial and distal sites (a possible total of 48 measurements per subject) from the CEJ to the alveolar crest in order to calculate differences in the linear alveolar bone height.
(2014) found that the height of the mandible at the mental foramen region and the distance from the superior margin of the foramen and the alveolar crest were significantly higher in males compared to females, it was suggested, therefore, that these traits can be used to determine sex.
