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.

Slight forward movement of point A occurred with the Alt-RAMEC protocol. The expansion affected not only the maxilla but also other structures of the face. Significant cutaneous changes occurred in the paranasal area. Some significant increase in the upper airway volume was obtained.

Aim: Incomplete polymerization of a resin material used for dental restoration affects the properties of the restoration. We evaluated the structural and mechanical properties of three different colored compomers cured with three different LED units to observe the characteristic changes occurring in different matches. Methods: Polytetrafluoroethylene molds (5 mm in diameter and 2 mm in thickness) were used to prepare disk-shaped sample specimens. Nine sample groups (each of five specimens) were prepared, three each of different compomer resin colors (gold, berry, and silver). Samples were cured using three different LED units (Optima, VALO, and Demi Ultra), according to the manufacturers' instructions. Microstructural properties of samples were characterized by determining the degree of curing using Fourier-transform infrared spectroscopy and by analyzing sample morphology under a scanning electron microscope. The Vickers hardness, compressive strength, and elastic modulus of the samples were measured to investigate their mechanical properties. Results: The degrees of curing decreased in the order of silver > berry > gold for all curing units. Conversely, gold compomers exhibited poorer mechanical values than the berry and silver counterparts. The Optima 10 unit yielded slightly higher degrees of curing than the other devices, followed by Demi Ultra and VALO light-curing units, respectively. Conclusion: The resin color affected the structural and mechanical properties of the compomers, possibly as a result of the complex interactions and relationships between the irradiation light and resin material, such as light absorbance and reflectance; thus, depending on the color as well as the curing protocol.
