Systemic parameters (waist circumference, blood pressure, lipid profile, and glycemic indices) and periodontal parameters (bleeding on probing, plaque score, probing depth, and clinical attachment loss) were assessed. aMMP-8 was evaluated qualitatively using point-of-care testing (PoCT) and quantitatively via ELISA in oral rinse, saliva, and GCF.The PoCT was positive in 90% of MetS-PD and 85% of SH-PD participants, while all SH-PH participants tested negative (<i>p</i> < 0.01). MetS-PD exhibited significantly higher aMMP-8 levels in oral rinse and saliva than SH-PD (<i>p</i> = 0.001), whereas GCF aMMP-8 levels were higher in SH-PD but not substantially different from MetS-PD (<i>p</i> = 0.086).

In contrast, crosslinked xenogeneic collagen matrix (Fibro-Gide) effectively enhances keratinized gingival thickness (KGT) but is unable to increase KGW. The aim of this study is to investigate the combined transplantation of Mucograft and Fibro-Gide in patients with thin gingival biotypes and insufficient KGW, evaluating whether this approach can simultaneously achieve both widening and thickening of the keratinized gingiva.

Comprehending the biomechanics of expansion appliances in individuals with UCLP is crucial in determining the suitable RPE design to rectify the asymmetric arch. This study used finite-element analysis (FEA) to investigate how scar contractures affect maxillary segments displacement during RPE in UCLP patients.A three-dimensional model of the maxilla was constructed from cone beam computed tomography images of an 11-year-old boy with UCLP who received RPE. ANSYS 2022 R2 software was employed to conduct FEA simulations with this model. Three forces were considered: expansion force, upper lip tension, and scar tension. Two simulation conditions were analyzed: a control scenario with only the expansion force and a second scenario with all three forces applied. Displacement was assessed in transversal (x-axis), vertical (y-axis), and sagittal (z-axis) directions at 14 reference points located across the palate and dentition.Both simulations exhibited similar patterns of maxillary displacement, but the magnitude of displacement was reduced when scar and lip tension were included. The minor segment exhibited a greater displacement than the major segment, with the largest movement occurring in the anterior region along the x- and z-axes, which gradually decreased posteriorly. The displacement pattern was as follows: x-axis > z-axis > y-axis for the major segment and z-axis > x-axis > y-axis for the minor segment.The FEA model demonstrated that RPE in UCLP produces an asymmetrical expansion with a pyramid-shaped displacement pattern. However, when scar tension from the palate and the upper lip is included, the extent of the segmental movement is reduced.
