AI Article Synopsis
- The study compares two surgical techniques, conventional and modified, for treating gingival recessions using an acellular dermal matrix graft (ADMG) instead of a subepithelial connective tissue graft (SCTG).
- Both techniques led to improvements in clinical parameters like probing depth and attachment levels after 6 months, but the modified technique had notably better results in reducing gingival recession and offered higher root coverage rates.
- The conclusion indicates that the modified surgical technique is more effective for root coverage with ADMG than the traditional method.
Article Abstract
Background: The acellular dermal matrix graft (ADMG) has become widely used in periodontal surgeries as a substitute for the subepithelial connective tissue graft (SCTG). These grafts exhibit different healing processes due to their distinct cellular and vascular structures. Therefore the surgical technique primarily developed for the autograft may not be adequate for the allograft. This study compared the clinical results of two surgical techniques--the "conventional" and a modified procedure--for the treatment of localized gingival recessions with the ADMG.
Methods: A total of 32 bilateral Miller Class I or II gingival recessions were selected and randomly assigned to test and control groups. The control group received the SCTG and the test group the modified surgical technique. Probing depth (PD), relative clinical attachment level (RCAL), gingival recession (GR), and width of keratinized tissue (KT) were measured 2 weeks prior to surgery and 6 months post-surgery.
Results: Both procedures improved all the evaluated parameters after 6 months. Comparisons between the groups by Mann-Whitney rank sum test revealed no statistically significant differences in terms of CAL gain, PD reduction, and increase in KT from baseline to 6-month evaluation. However, there was a statistically significant greater reduction of GR favoring the modified technique (P = 0.002). The percentage of root coverage was 79% for the test group and 63.9% for the control group.
Conclusion: We conclude that the modified technique is more suitable for root coverage procedures with the ADMG since it had statistically significant better clinical results compared to the traditional technique.

Association of Gingival Thickness With Incisor Morphological Characteristics and Papilla Height: A Cross-Sectional Study.

Objective: The aim of the current study was to examine possible associations between gingival thickness and other parameters, such as crown length and width, papilla height and patient's age and gender.
Overview: This cross-sectional study included 238 consecutive white Caucasian consecutive patients in all stages of orthodontic treatment (before, in-course, and after orthodontic treatment). Measurements of gingival thickness were carried out at both central mandibular incisors, mid-facially on the buccal aspect of each tooth, and 2 mm apically to the free gingival margin, with an Ultrasound device.
This case report introduced a new technique to manage buccal deep isolated recession with loss of keratinized tissue. This technique is indicated where there is a good amount of keratinized tissue lateral to the defect and deep vestibule. In this case report, a 27-year-old male patient was referred to a periodontal surgery clinic for the management of an 8 mm buccal recession with loss of keratinized tissue related to auto-transplanted maxillary molar that caused discomfort to the patient.

Objective: This study compared the fracture load, stress distribution, and survival probability under cyclic loading of extensively restored teeth treated with multisonic irrigation with those treated with conventional instrumentation, with or without a post.
Methods: Mesial-occlusal-distal cavities were prepared in 30 human mandibular premolars. The teeth were randomly divided into 3 groups of 10 based on the endodontic and restorative procedures: (1) Root canal treatment (RCT) followed by resin composite restoration (control group), (2) RCT followed by a glass fiber post restoration (conventional group), and (3) minimal instrumentation plus multisonic irrigation followed by resin composite restoration (GW group).

DNA methylation at age-related CpG (AR-CpG) sites holds significant promise for forensic age estimation. However, somatic models perform poorly in semen due to unique methylation dynamics during spermatogenesis, and current studies are constrained by the limited coverage of methylation microarrays. This study aimed to identify novel semen-specific AR-CpG sites using double-enzyme reduced representation bisulfite sequencing (dRRBS) and validate these markers, alongside previously reported sites and neighboring CpGs, using bisulfite amplicon sequencing (BSAS) to develop robust age estimation models.

Background: For a periodontist, treating recession is always a proud moment and a challenging task. The current trial aimed at comparing and clinically evaluating semilunar coronally repositioned flap (SCRF) and coronally advanced flap (CAF) procedures combined with platelet-rich fibrin (PRF) in the management of Miller's Class I recession defects.
Materials And Methods: Thirty-six recession sites were randomly divided into the CAF or SCRF groups.
