Background Gingival thickness, keratinized tissue width, and bone morphotype are three important parameters used to categorize periodontal phenotypes. These elements all play an important role in the maintenance of periodontal health. The aim of this review is to explore the importance of converting thin phenotype into a thick phenotype for periodontal health maintenance. Methods Three clinically relevant focused questions were defined to understand the role of gingival phenotype around teeth. 1) What are the factors affecting gingival phenotype (e.g., age, sex, dental arch, race, crown forms, etc.)? 2) Is there a difference between thin versus thick gingival phenotype in terms of gingival health? 3) Does the conversion of gingivae from a thin to thick gingival phenotype in sites without mucogingival defects help with periodontal health maintenance? Results Extensive electronic and manual literature search identified a total of 1,129 citations. After title, abstract, and full‐text screenings, 30 articles were included in the present review. Twenty‐five studies met the inclusion criteria and provided data for focused question 1. It was found that periodontal phenotype varies among different individuals and different areas of the mouth within the same individual. Asian individuals tend to have thinner gingival phenotype compared with white subjects. Eleven studies met the inclusion criteria for the focused question 2. Prevalence and severity of gingival recession was higher at the sites with thin gingiva compared with the sites with thicker gingiva. No studies provided data for focused question 3. Conclusions Available evidence indicates that subjects with thin and narrow gingiva tend to have more gingival recession compared with those with thick and wide gingiva. Currently, there is no published evidence to support conversion of thin to thick gingival phenotype in sites without gingival recession or mucogingival deformity.

“…Gingival phenotype refers to gingival thickness (GT) and keratinized tissue width (KTW) (Muller & Eger, ). Bone morphotype measurement with cone‐beam computed tomography (CBCT) has not been recommended (Jepsen et al, ) since there is a correlation between the GT and the buccal bone plate (Ghassemian et al, ; Zweers, Thomas, Slot, Weisgold, & Van der Weijden, ).…”

Aim The aim of this present study was to evaluate the effect of gingival thickness (GT) and keratinized tissue width (KTW) using injectable platelet‐rich fibrin (i‐PRF) alone and with microneedling (MN) in individuals with thin periodontal phenotypes. Materials and Methods In this split‐mouth study, 33 systemically healthy patients with thin periodontal phenotypes were randomly treated with MN + i‐PRF and i‐PRF. I‐PRF was injected on one side, and MN + i‐PRF was performed on the other side of the same patient at 4 sessions with 10‐day intervals. Clinical periodontal measurements, GT and KTW were assessed before the treatment and every month for six months after the final injection. Results After the evaluation of GT between the groups, a statistically significant difference was found in MN + i‐PRF group at the sixth month. In the intra‐group comparisons, a statistically significant increase in GT was observed within both i‐PRF [from 0.43 mm ± 0.14 to 0.62 mm ± 0.11 (p < .001)] and MN + i‐PRF [from 0.4 mm ± 0.14 to 0.66 mm ± 0.12 (p < .001)] groups at the sixth month. Conclusions In individuals with thin periodontal phenotypes, standalone i‐PRF and i‐PRF with MN may have an influence in increasing GT. The results suggest that application of i‐PRF and MN may be a first step of non‐surgical method for increasing gingival thickness.

Objectives: To investigate the association between the periodontal soft tissue, alveolar bone and dental parameters surrounding the incisors at baseline in patients with skeletal Class III malocclusion. Materials and Methods: The study sample comprised 154 teeth from 28 patients with skeletal Class III malocclusion (19 men and 9 women, 21.15 6 4.02 years). Periodontal soft tissue examination and hard tissue measurements with cone-beam computed tomography (CBCT) were performed. Factor analysis was used to reduce the CBCT variables, and correlation analysis between the hard tissue factors and soft tissue parameters was performed. Differences in hard tissue parameters between thick and thin gingival types were evaluated. Results: CBCT measurements were reduced to three hard tissue factors: lingual plate, coronalbuccal plate, and apical-buccal plate. Keratinized gingiva width and thickness were positively correlated with the coronal-buccal plate factor and negatively correlated with the apical-buccal plate factor. In the thin gingival biotype, mandibular incisors were more proclined, and the apical part of the buccal alveolar plate and the coronal part of lingual alveolar plate were thicker than in the thick gingival biotype. Conclusions: In the anterior teeth in cases of skeletal Class III malocclusion, hard tissue structures on the buccal side can be grouped based on coronal and apical factors that are significantly correlated with keratinized gingival width and thickness. Thick and thin gingival biotypes exhibited differences in tooth inclination and alveolar plate thickness with regard to the mandibular incisors. (Angle Orthod. 2018;88:91-99.)
