Clinical efficacy of intraoral ultrasonography versus transgingival probing for measurement of gingival thickness in different gingival biotypes: a clinical trial.

Background: Transgingival probing is conventionally used for gingival thickness (GT) measurement. However, invasiveness is a major drawback of transgingival probing. Thus, researchers have been in search of alternative methods for measurement of GT.

Morphological Variations of the Posterior Mandible: Proposing a Classification for Ridge Morphology Based on Cone-Beam Computed Tomography Data.

This study sought to assess the morphological variations of the posterior mandible and propose a classification for ridge morphology based on cone-beam computed tomography (CBCT) data. This retrospective, cross-sectional study evaluated 130 CBCT scans of patients with edentulous mandibles. Qualitative variables including lingual and crestal concavity, vertical, horizontal and angular limitations, and ridge morphology were assessed at 631 sites on CBCT scans of 87 males and 43 females.

Variations in bone quantity in the posterior mandible: a cross-sectional cone beam computed tomographic study.

In this retrospective cross-sectional study, cone beam computed tomography (CBCT) was used to assess the bone quantity variations in the posterior mandible of edentulous patients. The crestal cortical bone thickness, buccal cortical bone thickness, lingual cortical bone thickness, ridge height, ridge width, ridge angle, lingual concavity depth, and cortical to cancellous bone surface area ratio were measured at 631 sites on 130 CBCT scans of edentulous patients. The patient sample comprised 87 men and 43 women with a mean (SD) age of 63.
