All cultivated Patescibacteria, or CPR, exist as obligate episymbionts on other microbes. Despite being ubiquitous in mammals and environmentally, molecular mechanisms of host identification and binding amongst ultrasmall bacterial episymbionts are largely unknown. Type 4 pili (T4P) are well conserved in this group and predicted to facilitate symbiotic interactions.

Introduction: Implant failures resulting from peri-implant infections can have substantial consequences, underscoring the urgent need for effective strategies to prevent biofilm formation on implant surfaces. However, despite advancements in antimicrobial surface technologies, significant challenges persist in translating these innovations into clinically viable solutions.
Areas Covered: This article provides an overview of the limitations of current treatment protocols and explores the potential of antimicrobial surface treatments for controlling such infections.

Periodontitis is a chronic inflammatory disease driven by the accumulation of bacterial plaque and the host's immune response, leading to the destruction of periodontal tissues. Nutrition, particularly the intake of micronutrients with anti-inflammatory and antioxidant properties, plays a crucial role in maintaining periodontal health. This review explores the impact of various micronutrients-vitamins (A, B, C, D, E), minerals (calcium, iron, zinc, potassium, copper, manganese, selenium), and omega-3 fatty acids-on periodontal disease prevention and management.

The necessity for regenerating peri-implant and periodontal tissues is increasingly apparent. Periodontal diseases can result in a significant loss of clinical attachment level, and tissue regeneration stands as the ultimate goal of periodontal therapy. With the rise of osseointegration, the prosthetic rehabilitation of missing teeth using dental implants has surged, leading to a frequent need for alveolar bone regeneration around implants.

The present review summarizes the findings from human histological studies conducted over the past 20 years at the University of Guarulhos, Brazil, examining the impact of various implant surface topographies and smoking on peri-implant bone response. Seven different implant surfaces were evaluated in 90 partially or completely edentulous individuals using a total of 123 micro-implants. Histometric parameters, including bone-implant contact (BIC%), bone area within the threads (BA%), and bone density (BD), were assessed after an 8-week healing period.

Nonsurgical therapies have been recommended and employed as a less invasive and cost-effective modality in managing periodontitis. In this context, different therapeutic protocols have been tested in the last decades. Therefore, mapping the scientific trends and patterns provides critical insights into the state of research in the field, which has not been explored for overall nonsurgical periodontitis treatment studies.

This study quantified the production of the pro-resolving agent Resolvin E1 by peripheral blood mononuclear cells (PBMC) from 20 systemically healthy volunteers with and without periodontitis after stimulation with lipopolysaccharide (LPS) from Porphyromonas gingivalis (Pg). Ten periodontitis patients and 10 healthy volunteers (30-50 years old), matched by age and sex, were recruited. Peripheral blood mononuclear cells were isolated and stimulated in culture plates for 24 hours with Pg LPS.

Implant-supported immediate loading full-arch rehabilitation has been documented in the literature. More recently, computed surgical guides have frequently been used since they facilitate planning and performing surgical treatment without the need to raise a flap, thus reducing trauma and morbidity. This case report describes an immediate full-arch, fixed rehabilitation with full loading placed on four commercially available 3D-printed implants, with a 24-month follow-up.

Implantable biomedical devices have found widespread use in restoring lost functions or structures within the human body, but they face a significant challenge from microbial-related infections, which often lead to implant failure. In this context, antimicrobial hydrogels emerge as a promising strategy for treating implant-associated infections owing to their tunable physicochemical properties. However, the literature lacks a comprehensive analysis of antimicrobial hydrogels, encompassing their development, mechanisms, and effect on implant-associated infections, mainly in light of existing in vitro, in vivo, and clinical evidence.

To provide an overview of the use of autogenous platelet concentrates (APCs) in periodontal regeneration and to conduct a systematic review (SR) of the treatment outcomes of periodontal intrabony defects by using platelet-rich fibrin (PRF) compared with other commonly utilized modalities. The eligibility criteria comprised randomized controlled trials (RCTs) comparing the clinical outcomes of PRF with that of other modalities. Studies were classified into 21 categories and into five different groups as follows: Group I (1) open flap debridement (OFD) alone versus OFD/PRF, (2) OFD versus Titanium-PRF (T-PRF) Group II, (3) Comparative PRF protocols (PRF vs.

Background: With advancements in orthodontic technology, treatment durations have shortened, often concluding at earlier ages. This shift prompts scrutiny of contemporary retention and post-treatment protocols. The study aimed to assess current professional preferences, compare them against patient age and treatment duration, and investigate the potential impacts of reduced treatment times on professional protocols, particularly when treatment concludes before pubertal growth.

The objective of the study was to compare the treatment outcomes of periodontal furcation defects by using platelet-rich fibrin (PRF) with other commonly utilized modalities. The eligibility criteria comprised randomized controlled trials (RCTs) comparing the clinical outcomes of PRF with those of other modalities for the treatment of furcation defects. Studies were classified into 11 categories in 3 different groups as follows: Group I (addition of PRF): (1) open flap debridement (OFD) alone versus OFD/PRF, (2) OFD/bone graft (OFD/BG) versus OFD/BG/PRF; Group II (comparative studies to PRF): (3) OFD/BG versus OFD/PRF, (4) OFD/collagen membrane versus OFD/PRF, (5) OFD/PRP versus OFD/PRF, (6) OFD/rhBMP2 versus OFD/PRF; and Group III (addition of biomaterial/biomolecule to PRF): OFD/PRF versus … (7) OFD/PRF/BG, (8) OFD/PRF/amniotic membrane (AM), (9) OFD/PRF/metformin, (10) OFD/PRF/bisphosphonates, (11) OFD/PRF/statins.

This study evaluated the efficacy of synthetic bone blocks, composed of hydroxyapatite (HA) or β-tricalcium phosphate (B-TCP), which were produced by additive manufacturing and used for the repair of critical size bone defects (CSDs) in rat calvaria. Sixty rats were divided into five groups ( = 12): blood clot (CONTROL), 3D-printed HA (HA), 3D-printed β-TCP (B-TCP), 3D-printed HA + autologous micrograft (HA+RIG), and 3D-printed β-TCP + autologous micrograft (B-TCP+RIG). CSDs were surgically created in the parietal bone and treated with the respective biomaterials.

Titanium (Ti) is an ideal material for dental implants due to its excellent properties. However, corrosion and mechanical wear lead to Ti ions and particles release, triggering inflammatory responses and bone resorption. To overcome these challenges, surface modification techniques are used, including micro-arc oxidation (MAO).

This clinical report presents a technique to reconstruct extensively resected mandibles using a combination of autologous bone grafts and additive manufacturing techniques. Mandibular defects, often arising from trauma, tumors, or congenital anomalies, can severely impact both function and aesthetics. Conventional reconstruction methods have their limitations, often resulting in suboptimal outcomes.
