The emerging field of senolytics is centered on eliminating senescent cells to block their contribution to the progression of age-related diseases, including cancer, and to facilitate healthy aging. Enhancing the selectivity of senolytic treatments toward senescent cells stands to reduce the adverse effects associated with existing senolytic interventions. Taking advantage of lipofuscin accumulation in senescent cells, we describe here the development of a highly efficient senolytic platform consisting of a lipofuscin-binding domain scaffold, which can be conjugated with a senolytic drug via an ester bond.

Methods: Thirty-nine patients planned for two similar flap surgeries under IV sedation were included. Before the first surgery, patients were randomized to receive 8 mg of IV or submucosal dexamethasone.
Background: This study compared titanium and zirconia implant ligature-induced peri-implant defect progression and response to regenerative surgical intervention.
Methods: Eight tissue-level endosseous implants were placed in 6 mixed-breed foxhounds, with 2 zirconia and 2 titanium alternating in each hemimandible. Cotton ligatures were placed subgingivally for 16 weeks followed by 8 weeks of spontaneous progression.
Objective: To evaluate the possible association between thyroid function within the euthyroid range and musculoskeletal parameters as well as body composition in a sample of postmenopausal women.
Methods: This cross-sectional study included 96 postmenopausal women with serum thyroid-stimulating hormone (TSH) within the normal laboratory reference range. Fasting venous blood samples were obtained for biochemical/hormonal assessment.
Background: Alveolar ridge preservation (ARP) procedures are designed to lessen dimensional changes in the alveolar ridge after tooth extraction. Wound healing after ridge preservation involves the formation of new vital bone in the former socket, and this vital bone is important in the osseointegration of dental implants.
Methods: A series of ARP studies have been performed to help clinicians better understand the wound-healing events that occur following tooth extraction and ridge preservation.
Background: Peri-implantitis is a frequent finding. Initial treatment involves non-surgical debridement of the implant surface. Recent studies have found a correlation between titanium (Ti) particle release and peri-implantitis, yet there is a dearth of information regarding the effect of various non-surgical instrumentation on particle release or peri-implantitis resolution.

The secondary aim is to determine the patient and professional evaluation of color match and graft texture between the two groups.
Methods: Patients with ≤2 mm keratinized tissue indicated for a FSTA were randomly assigned to control group (FSTA with epithelium) or test group (de-epithelialized FSTA).
Focused Clinical Question: What are the appropriate preparation protocols for autologous blood products to support their clinical utilization?
Summary: Autologous blood products provide a unique clinical benefit. Their popularity among the professions is growing. However, as this is a rapidly evolving field, multiple modalities are presented within the literature.
Background: This randomized controlled trial was designed to evaluate the histological wound healing and alveolar ridge dimensional changes following ridge preservation using two different xenograft/collagen matrices.
Methods: Fifty-four patients each with non-molar teeth that required extraction and replacement with dental implants were enrolled. Teeth extractions were completed with minimal flap reflection and were randomized to receive ridge preservation with either 90% bovine-derived xenograft granules in a 10% porcine collagen matrix (Group A) or a sponge-like matrix of 80% microparticulate hydroxyapatite alloplast graft with 20% sugar cross-linked porcine type 1 collagen (Group B).
To evaluate the effectiveness of a structured education program on lifestyle habits, which is also incorporating teaching on deep breathing, progressive muscle relaxation, and guided visualization, in the control of various components of the climacteric symptomatology in peri- and postmenopausal women. Sixty-one women aged 40-65 years with varying climacteric and stress symptoms were included in this study. Women were randomly assigned to the intervention group (31) or the control group (30).

Importantly, a new classification scheme for periodontal and peri-implant treatments has recently been devised that is incorporating current evidence and enabling patient-specific periodontal care. However, this important progress can be further accelerated with the availability of patient-perceived outcomes of periodontal and implant interventions.

Material And Methods: This was a retrospective chart review and radiographic analysis of patients that had undergone lateral window sinus augmentation with PRGF and had dental implants placed at least 6 months post augmentation. All implants included were followed up for at least one year after placement.
Objectives: The purpose of this study was to evaluate the effect of chlorhexidine and essential oils containing mouth rinses on oral wound healing after periodontal flap surgery.
Materials And Methods: Eighty subjects participated in the study and were randomly assigned to use water, 0.12% chlorhexidine (CHX), essential oils (EO), 5% CHX, and 10% EO.
Background: The aim of this study was to identify any associations between predictor variables, mainly clinician training and dental implant outcome, among the residents in different departments and to compare statistical analysis with the use of MATLAB R2017a™ to SAS version 9.4.
Methods: Dental records were reviewed from January 1, 2011, to December 31, 2015.
Purpose: This systematic review aimed at assessing the effects of PRGF in new bone formation, soft tissue healing and post-operative pain and swelling in sites that underwent ridge preservation, ridge augmentation and maxillary sinus augmentation procedures.
Materials And Methods: A comprehensive literature search employing seven databases was conducted by two independent reviewers. Only randomized and non-randomized controlled clinical trials using PRGF alone or in combination with bone grafting materials were selected.

This systematic review aimed to assess the effects of leukocyte-platelet-rich fibrin (L-PRF) on bone regeneration, soft tissue healing, and postoperative complications in patients undergoing ridge preservation, ridge augmentation, and maxillary sinus augmentation procedures. A comprehensive literature search was conducted by two independent reviewers. Only randomized and non-randomized controlled clinical trials were selected.

Introduction: Acellular dermal matrix (ADM) is a cell-free dermal matrix comprised of a structurally integrated basement membrane complex and extracellular matrix in which collagen bundles and elastic fibers are the main components. There are several commercially available ADM allografts that have different processing methods. This case series reports the histologic presentation of two of the most widely used ADM allografts, referred to as ADM-A and ADM-B, in patients that had specific situations involving reentry.

But in some cases the degree of impulsivity begins to create negative effects on one's life and acquires pathological connotation. Two clinical entities in which can be observed a high degree of impulsivity is Attention Deficit Hyperactivity Disorder (ADHD) and Addictive disorders.

Methods: Twenty-seven patients (30 implants) were divided into three groups. All implants were 4 mm wide in diameter and 8 mm long.
Objective: The adaptation of the brain to aging is subject to the impact of psychological and environmental factors and possibly climacteric symptomatology. We aimed to determine the association of climacteric symptomatology with different aspects of episodic memory in a sample of Greek menopausal women.
Methods: This cross-sectional study included 39 postmenopausal women with subjective memory complaints.
This investigation was undertaken to determine if multithreaded implants partially coated with plasma-sprayed hydroxyapatite (HA) could be effectively loaded earlier than 3-6 months after placement. Forty-eight patients (22 men, 26 women) were enrolled in the study and received 48 implants. The population was divided into 2 groups: A implants (n = 23) were loaded immediately on the day of surgery and group B implants (n = 19) were loaded 3 weeks after surgery.
