CTG and CTG + PR were effective to treat CD. Use of PR resulted in better gingival margin contour and DH reduction, without effect on CD coverage by CTG. (NCT02817763).

Diabetes has become a global epidemic. Its complications can have a significant impact on quality of life, longevity, and public health costs. The presence of diabetes might impair the prognosis of periodontal treatments due to its negative influence on wound healing. Antimicrobial photodynamic therapy (aPDT) is a local approach that can promote bacterial decontamination in periodontal pockets. The aim of this study was to investigate the local effect of adjunct aPDT to ultrasonic periodontal debridement (UPD) and compare it to UD only for the treatment of chronic periodontitis in type 2 diabetic patients. Twenty type 2 diabetic patients with moderate to severe generalized chronic periodontitis were selected. Two periodontal pockets with probing depth (PD) and clinical attachment level (CAL) ≥5 mm received UPD only (UPD group) or UPD plus adjunct aPDT (UPD + aPDT group). Periodontal clinical measures were collected and compared at baseline and 30, 90, and 180 days. After 180 days of follow-up, there were statistically significant reductions in PD from 5.75 ± 0.91 to 3.47 ± 0.97 mm in the UPD group and from 6.15 ± 1.27 to 3.71 ± 1.63 mm in the UPD + aPDT group. However, intergroup analysis did not reveal statistically significant differences in any of the evaluated clinical parameters (p > 0.05). The adjunct application of aPDT to UPD did not present additional benefits for the treatment of chronic periodontitis in type 2 diabetic patients. The ClinicalTrials.gov identifier of the present study is NCT02627534.

Introduction Gingival recession (GR) is a prevalent problem that is related to esthetic demands and dentin hypersensitivity. Frequently, GR is associated with non‐carious cervical lesion (NCCLs) forming a combined defect (CD), which requires restorative and surgical treatment. Connective tissue graft procedures allow predictable root coverage but can result in patient discomfort. Case Presentation This first case report describes multiple GRs associated with B+ NCCL at teeth #4 and #6 of a 27‐year‐old patient with a thin periodontal phenotype. The aim of this report was to evaluate the 6‐month outcome of a new volume‐stable collagen matrix (VCMX) combined with modified coronally advanced flap (MCAF) and partial restoration to treat CDs. After 6 months, significant improvement was observed regarding CD coverage (69.05%), recession reduction (2.25 mm), gingival thickness gain (0.74 mm), and keratinized tissue width gain (0.75 mm). In addition, excellent esthetic evaluation and patient comfort were achieved by using the biomaterial. Conclusion VCMX associated with MCAF and partial restoration may be an option to treat multiple recession defects plus B+ NCCLs.
