“…5 In the present study the periodontal probing depth was associated with thicker gingiva among the cases, which was in accordance with observations made by several other authors who also reported that subjects with a thick periodontal phenotype had on an average higher mean periodontal probing depth. 19,20,21 However, such a correlation between the probing depth and gingival thickness did not exist in the control group.…”

CONTEXTThe harmony and beauty of a smile are characterized by both our teeth and gums, wherein the gingival display in the maxillary anterior teeth is more apparent than that of the posterior teeth. Anatomical characteristics of the periodontium, such as width of keratinized tissue and gingival thickness are known to reflect the health of the periodontium. Hence, it is cardinal to establish a relationship between the gingival parameters like the width of keratinized gingiva and the thickness of gingiva with the periodontal status in the anterior teeth region. AIMThe objective of the study is to evaluate whether there is a positive correlation between the gingival thickness, width of the zone of gingival keratinized tissue and periodontal status. SETTINGS AND DESIGNThis is a comparative clinical study with a sample size of 120, of which 60 patients having periodontitis in the maxillary and mandibular anterior teeth regions were regarded as cases and 60 patients without any form of periodontitis in the maxillary and mandibular anterior teeth regions were regarded as controls. METHODS AND MATERIALSIn all subjects, periodontal parameters like plaque index, gingival index, bleeding index, probing depth, clinical attachment level, width of keratinized gingiva and the number of recessions were recorded. The thickness of gingiva was recorded using an endodontic spreader and digital calipers. STATISTICAL ANALYSISKarl Pearson correlation coefficient and unpaired t test were used for statistical analysis. RESULTSAmong the cases, plaque index and gingival index negatively correlated with the width of keratinized tissue, the width of keratinized tissue positively correlated with thickness of gingiva and the probing depth, clinical attachment level and gingival recessions were negatively correlated with the width of keratinized tissue. The control group showed a positive correlation between the width of keratinized tissue, the probing depth and clinical attachment level. CONCLUSIONThere exists a difference in the width of keratinized tissue and gingival thickness among periodontitis patients and controls. Moreover, periodontal parameters like probing depth, clinical attachment level and incidence of gingival recession correlate with the width of keratinized gingiva and gingival tissue thickness in the anterior teeth region.

Although ultrasonography is a non-invasive, inexpensive and painless diagnostic tool for soft tissue imaging, this technique is not currently used for oral exploration. Therefore, we developed a 25-MHz high-frequency ultrasound probe, specially designed for intraoral applications. This paper aims to present clinical intraoral ultrasound images actually interpretable, in order to identify the relevant applications of this novel tool and to design future oral studies. Two independent radiologists performed ultrasound examinations on three healthy volunteers. All the teeth were explored on the lingual and buccal sides (162 samples) to evaluate the ergonomics of the system and the visualisation of anatomic structures. Osseointegrated dental implants and a mucocele were also scanned. At the gingivodental junction of the maxillary and mandibular teeth, the device clearly identifies the tooth surfaces, the alveolar bone reflection with its surrounding subepithelial connective tissue of the gingiva and the gingival epithelia. The bone level and the thickness of soft tissue around the implant are measurable on the buccal and lingual sides. Therefore, intraoral ultrasonography provides additional morphological information that is not accessible by conventional dental x-rays. We propose a novel diagnostic tool that explores the biological width and is able to define the thin or thick nature of the gums. Moreover, intraoral ultrasonography may help to monitor precancerous lesions. This promising device requires large-scale clinical studies to determine whether it should remain a research tool or be used as a diagnostic tool for daily dental practice.

“…Transgingival probing method, which is a direct invasive measurement involving a periodontal probe, may be influenced by the diameter, angulation, and pressure of the periodontal probe and may cause the distortion of the tissue on probing; it is, however, simple and relatively inexpensive 3,10) . The ultrasonic method is also simple; however, the area available for study is limited by the large diameter of the probe and the results may be influenced by humidity 11,12,16,17) . Recently, many studies using radiographic measurements with CBCT have been reported.…”

Purpose: The purpose of this study was to assess the relationship between gingival biotype and underlying crestal bone morphology in the maxillary anterior region. Materials and Methods:The maxillary anterior teeth from 40 subjects (20 thin biotype, 20 thick biotype) with ages from 20 to 50 years were included in this study. All subjects had healthy gingiva in the maxillary anterior region and had no history of orthodontic treatment, periodontal treatment, or hyperplastic medication. Using the probe transparency method, the scalloped distance (SCD) between the contact point-bone crest and the midface-bone crest was measured for each maxillary anterior teeth of two groups.Result: The mean SCD was 3.00±0.21 mm in thin biotype and 2.81±0.20 mm in thick biotype. The SCD value in the thin biotype was statistically significantly greater than in the thick biotype (t=2.982, P<0.01). Comparing the degree of crestal bone scallop in each maxillary anterior teeth in the two groups, all six teeth in the thin biotype showed higher bone scallop than in the thick biotype. Conclusion:A simple procedure using a probe could to determine gingival biotype and to predict the underlying crestal bone morphology was introduced. This may be useful for effective treatment planning.

Variance components of gingival thickness

Abstract: Gingival thickness is mainly associated with tooth-related variables. Bleeding tendency is higher if gingiva is thin. Subject variability related to periodontal phenotype may add to the total variance, however, to a very low extent.
