“…The premolar GT3 in the study sample group ranged from 0.9 mm to 1.35 mm. This value is a little higher than the 0.9 mm-to-1.06 mm range reported by Ganji et al [19] using the A-mode US method at a location 3 mm apical to the CEJ in the maxillary premolars and lower than the 1.91±0.41mm reported by Gurlek et al [20] using CBCT at the same locations analyzed in our study. Discrepancies might be caused by differences in the methods, sample sizes and ages as Wara et al [21] reported that participants in a younger age group had significantly thinner mucosa than those in the older age group.…”

“…Clinical B-mode US examination Fifty periodontally healthy participants (25 men; mean age 25.8±4.4 [range, [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]] years) and their 400 premolar teeth were included in this study. The premolars were imaged with the 15 MHz B-mode US device from the buccal side.…”

Aims: Knowledge of gingival thickness (GT) and alveolar crest thickness (ACT) is essential for performing various surgical and non-surgical procedures in oral healthcare. However, a noninvasive, no-radiation and reproducible method for measuring GT and ACT is not yet determined. This study aimed to measure the buccal GT and ACT of premolars using 15-MHz B-mode ultrasonography (US) and to explore the relationship between GT and ACT.Material and methods: The GT in four swine mandibles was measured using15-MHz B-mode US and using K-file needles to gauge the accuracy of US. B-mode US at 15 MHz was also used to measure periodontal tissue structures including buccal GT3 (3 mm apical to the gingival margin) and ACT in 400 premolars of 50 human participants with healthy periodontium.Results: There was a strong positive correlation between US and invasive K-file needle measurements of GT in swine mandibles (p<0.05). The correlation between buccal GT3 and ACT of premolars was moderately positive (p<0.05). The gingiva of the maxillary premolars and ACT of the maxillary first premolars were thicker in men than in women (p<0.05).Conclusions: B-mode US at 15 MHz is a valid and reliable method for measuring GT and ACT and for evaluating their relationship.

“…Hence, the examination paradigm and diagnostic standard must be established for gingival phenotype assessment based on multiple clinical scenarios. To date, several studies have compared ultrasonic devices or CBCT as measuring tools with transgingival probing individually 21–24 . However, no systematic review has evaluated gingival thickness measurement methods.…”

Objective Measurement of the periodontal soft tissue dimension is crucial for clinical decision‐making and aesthetic prognosis. However, the effectiveness of different measuring methods remains unclear. This systematic review aimed to explore the diagnostic accuracy of two non‐invasive methods (namely CBCT and ultrasound) for gingival thickness measurement at different tooth positions. Materials and methods A systematic search was performed using PubMed (including Medline), PubMed Central, OVID, Cochrane Library, LILACS and OpenGrey. Studies focusing on comparisons between CBCT, ultrasound and direct transgingival probing were included. The means, SDs and correlation coefficients with 95% confidence intervals were extracted and analyzed using Review Manager and R software. Results Twelve studies were selected. No significant difference was found between CBCT measurement and transgingival probing in the anterior and posterior dentition, and a moderate correlation was observed between these two methods (r = 0.41). A weak correlation was found between ultrasound measurement and transgingival probing (r = 0.32), and a slight but statistically significant difference was found when comparing ultrasonic devices and transgingival probing in the posterior area. Conclusion CBCT can be considered a relatively reliable method for gingival thickness measurement in both the anterior and posterior areas compared with direct probing. Ultrasonic devices provide limited accuracy in the posterior area but are relatively comparable with direct clinical assessments in the anterior area. Clinical significance Measurement location may affect the diagnostic accuracy and repeatability of gingival thickness measurements. Appropriate method selection in different clinical scenarios is crucial to aesthetic outcome prediction and decision‐making.

“…The GT thickness can be measured with the use of invasive methods such as a needle, an endodontic tool, or a periodontal probe, or with the use of radiological methods like parallel profile radiographs and cone-beam computed tomography (CBCT) [ 12 – 16 ]. Noninvasive methods include using an ultrasonic device and optical coherence tomography [ 13 , 16 – 20 ]. Measurements of the WKT are most often carried out using a periodontal probe calibrated every 1 mm [ 20 ].…”

Background Two clinical parameters, the gingival thickness (GT) and the width of keratinized tissue (WKT), describe the gingival phenotype, which is defined as the 3-dimensional volume of the gingiva. The periodontal phenotype additionally includes the thickness of the labial plate of the alveolar crest (TLPAC). Material/Methods Thirty patients with healthy periodontium on the upper canines and incisors underwent measurements for crestal, supracrestal, free gingival thickness (FGT), the alveolar crest-gingival margin (AC-GM), alveolar crest-cementoenamel junction distance, and the TLPAC at 2, 4, and 8 mm apically from the edge of the alveolar crest using cone-beam computed tomography (CBCT) with computer-aided design and prosthetic-driven implant planning technology. For each tooth, the gingival and periodontal phenotype was evaluated on the basis of the gingival thickness, width of keratinized tissue (WKT), and TLPAC measurements. Each patient’s periodontal phenotype was evaluated according to the coronal width/length ratio of both the upper central incisors. Results The dentogingival units had varying average values for the 3 periodontal phenotypes (thin phenotype: FGT 0.65±0.06 mm, WKT 4.85±1.18 mm, AC-GM 3.17±0.64 mm, TLPAC2 0.66±0.28 mm; medium phenotype: FGT 0.87±0.07 mm, WKT 5.49±1.23 mm, AC-GM 3.36±0.65 mm, TLPAC2 0.76±0.37 mm; and thick phenotype: FGT 1.20 mm, WKT 6.00 mm, AC-GM 3.90 mm, TLPAC2 0.90 mm). Positive correlations were seen among WKT, FGT, AC-GM, and TLPAC2. Conclusions Positive correlations between the FGT and WKT, and the AC-GM distance confirm that measurements using CBCT with computer-aided design and prosthetic-driven implant planning technology can evaluate the gingival phenotype and TLPAC2 for the periodontal phenotype.
