Objectives: To investigate the correlation between gingival thickness (GT) and buccal bone thickness (BBT), as well as the effects of GT, BBT, bone crest level (BC), and tooth position on the buccal gingival margin location of maxillary teeth in the esthetic zone.
Materials And Methods: Periodontally healthy subjects with prior cone beam computed tomography and intraoral scans for dental implant planning were included. The hard and soft tissue measurements were retrospectively analyzed digitally.
Article Synopsis
- The study aimed to noninvasively measure supracrestal tissue attachment dimensions (STADs) and explore their relationships with other dental factors like gingival thickness and tooth position.
- Researchers involved 19 healthy subjects and utilized advanced imaging techniques and statistical analyses to assess 203 teeth, finding variations in STADs based on tooth location and associated factors.
- Results indicated that STADs were generally larger in mandibular teeth and showed complex correlations with gingival and bone characteristics, emphasizing the importance of tooth position in understanding STAD dynamics.
Periodontal disease is an infection-driven inflammatory disease characterized by the destruction of tooth-supporting tissues. The establishment of chronic inflammation will result in progressive destruction of bone and soft tissue changes. Severe periodontitis can lead to tooth loss.

It is well established that MAPK/NF-kB axis is a key signaling pathway engaged in osteoclast differentiation. It is stated that that biphasic calcium phosphate (BCP) and platelet-rich fibrin (PRF) have significant antiostoeclastogenic effects in chronic periodontitis.

Materials And Methods: A retrospective evaluation of 273 surgically placed dental implants with adequate preoperative cone-beam computed tomography (CBCT) between 2017 and 2019. Misch classification was used to assess the bone quality, and CBCT grayscale values, utilizing Hounsfield units (HU), were used for radiographic bone density assessment.
The present study aims to compare the levels of micro-RNA-146a and micro-RNA-126 in oral subgingival plaque and coronary plaque from artery walls in patients with coronary artery disease who suffer from generalized periodontitis. A total of 75 participants were selected and grouped into three categories of 25 patients each: GP+CAD, GP, and HP groups. GP+CAD consisted of patients diagnosed with generalized periodontitis (GP) and coronary artery disease (CAD).

Methods: Seventy-six subjects received 87 implants with a modified osteotome sinus elevation technique using BG bone graft and simultaneous implant placement. The radiographs taken at the time of implant placement and at the time of implant uncovery were retrospectively evaluated to assess the degree of BG dimensional changes.
