Relationship Between Gingival Thickness and Other Periodontal Phenotypical Features: A Cross-Sectional Study.

This study aimed at characterizing the gingival thickness (GT) and determining correlations with other local phenotypical features. Cone-beam computed tomography scans from adult subjects involving the maxillary anterior teeth were obtained to assess buccal GT at different apico-coronal levels, periodontal supracrestal tissue height (STH), the distance from the cementoenamel junction to the alveolar bone crest (CEJ-BC), and bucco-lingual tooth dimensions in mm. A total of 100 subjects and 600 maxillary anterior teeth constituted the study sample.

Relationship between soft tissue dimensions and tomographic radial root position classification system for immediate implant installation.

The aim of this study was to evaluate the relationship between soft tissue dimensions and radial root position (RRP) classification for immediate implant placement on maxillary anterior teeth. Maxillary anterior teeth (n = 420) were analyzed in the radial plane of cone beam computed tomography (CBCT) scans. Each tooth was classified according to its RRP: class I, (IA, IB); class II (IIA, IIB) class III; class IV, and class V.

Correlation of Gingival Stippling with Periodontal Phenotypic Features: A Cross-Sectional Study.

This study aimed to determine the correlation between gingival stippling (GS) and other phenotypic characteristics. Adult subjects in need of CBCT scans and comprehensive dental treatment in the anterior maxilla were recruited. Facial gingival thickness (GT) and buccal bone thickness (BT) were assessed utilizing CBCT.

Non-invasive assessment of peri-implant mucosal thickness: A cross-sectional study.

Background: This study aimed to evaluate the reliability and reproducibility of different non-invasive methods for the assessment of peri-implant mucosal thickness.

Methods: Subjects with two adjacent dental implants in the central maxillary region were included in this study. Three different methods to assess facial mucosal thickness (FMT) were compared: digital file superimposition using Digital Imaging and Communication in Medicine (DICOM) and stereolithography (STL) files of the arch of interest (DICOM-STL), DICOM files alone, and non-ionizing ultrasound (US).

Relationship between supracrestal soft tissue dimensions and other periodontal phenotypic features: A cross-sectional study.

Background: The purpose of this study was to determine the association between periodontal supracrestal soft tissue dimensions (PSSTDs) and other phenotypic features in non-molar maxillary teeth.

Materials And Methods: Adult subjects in need of comprehensive dental treatment were recruited. Periodontal phenotypic variables (i.

Current landmarks for gingival thickness evaluation in maxillary anterior teeth: a systematic review.

Objectives: To identify and report the current landmarks used for measuring gingival thickness (GT) in healthy maxillary anterior teeth.

Material And Methods: The protocol of this Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) 2020-compliant systematic review was registered in PROSPERO. A literature search was conducted to identify articles that met the eligibility criteria published up to 2022.

Relationship between smile type and periodontal phenotype: A clinical and tomographic cross-sectional study.

Objectives: To evaluate the correlation between smile type (ST) and the periodontal phenotype (PP).

Material And Methods: Clinical and photographic examinations of 164 participants (48 men and 116 women, mean age 22.9 ± 4.

Gingival landmarks and cutting points for gingival phenotype determination: A clinical and tomographic cross-sectional study.

Background: This cross-sectional study assessed the role of gingival landmarks (GLs) and cutting points (CPs) for gingival phenotype (GP) determination.

Methods: Six maxillary anterior teeth (70 subjects) were evaluated using soft tissue cone-beam computed tomography (ST-CBCT). Gingival thickness was measured at different GLs: 1) tissue zone (gingival margin [GM], 1 and 2 mm apical to GM, cemento-enamel junction, above the bone crest); 2) bone zone (buccal bone crest [BBC], 1, 2, and 3 mm apical to BBC).

Tomographic sagittal root position in relation to maxillary anterior bone housing in a Brazilian population.

Purpose: This cross-sectional study evaluated and categorized the tomographic sagittal root position (SRP) of the maxillary anterior teeth in a Brazilian population.

Materials And Methods: Cone-beam computed tomographic scans of 420 maxillary anterior teeth of 70 patients (35 men and 35 women, mean age 25.2±5.

Micro-tomographic analysis of the root trunk and pre-furcation area of the first mandibular molars.

This study analyzed the root trunk (RT) and the pre-furcation area (PFA) of mandibular first molars. Thirty lower first mandibular molars extracted due to advanced periodontal disease were evaluated in a high-energy spiral computerized micro-tomography. Two gutta-percha markings on the cementoenamel junction (CEJ) and at the furcation entrance (FE) at buccal and lingual surfaces served as reference points for measurements of RT length, and PFA width and depth, at the levels of CEJ, 1 mm apical to CEJ, 2 mm apical to CEJ, and at the FE.

Biometric study of the prefurcation area of human mandibular first molars.

This study analyzed the length of the root trunk (RT) as well as the width and depth of the prefurcation area (PFA) of human mandibular first molars. Ninety-six human mandibular first molars that were extracted after being observed to be in poor condition both clinically and radiographically were used in this study. A contour-measuring instrument was used, and profiles of the buccal and lingual root surfaces of these teeth were traced on a millimeter-scaled paper.

Evaluation of a dense polytetrafluoroethylene membrane to increase keratinized tissue: a randomized controlled clinical trial.

Background: The presence of an adequate zone of keratinized tissue has been associated with implant health. This study evaluated the increasing of the zone of keratinized tissue using dense polytetrafluoroethylene (d-PTFE) membranes over extraction sites, without primary closure.

Materials And Methods: Fifteen sites received d-PTFE membranes.

Supracrestal gingival tissue measurement in normal periodontium: a human histometric study.

Twenty-four teeth were extracted en bloc with the marginal periodontal structures and processed for histologic purposes. Measurements were taken from the top of the gingival margin to the apical limit of the junctional epithelium (GM-JE), from the apical limit of the junctional epithelium to the top of the alveolar bone crest (JE-AB), and from the top of the gingival margin to the top of the alveolar bone crest (GM-AB). Data were histometrically analyzed.
