Between the 20th and 21st centuries, periodontal disorders became common. Inflammatory periodontal disorders affect 90–95% of cases, while 80% of children have some kind of periodontal disease and over 95% of people over the age of 35 years have some form of periodontal disease. The gums, cement, alveolar bone, and other periodontal tissues can all sustain damage from the illness known as periodontitis. There are several reasons for this, such as smoking, poor oral hygiene, genetics, and other t

Orthodontic devices can disturb the balance of oral biofilms, increasing plaque accumulation and the risk of oral disease, with elastomeric modules (EMs) particularly prone to bacterial colonization due to their material properties. Surface modifications have been explored to limit microbial growth. This study investigated the mechanical performance, antibacterial effects, and cytocompatibility of chitosan-based coatings applied to EMs. EMs were coated with either chitosan (CS) or chitosan cross

Odontomas, the most prevalent mixed odontogenic tumors, can obstruct the eruption of adjacent teeth and cause functional difficulties in mastication. Management of tooth impaction associated with odontomas depends on the stage of root development and the tumor’s location within the alveolar bone. This case report aims to illustrate the outcomes of combined surgical and orthodontic management in growing patients with odontomas. Two pediatric patients—a 8-year-old boy and a 17-year-old girl—presen

Traditionally, dental implants are placed several months following tooth extraction. Immediate implants, however, are inserted on the same day as extraction, preserving the crestal bone. Immediate loading allows for prosthetic reconstruction within forty eight hours of implant placement. This study aimed to evaluate peri‑implant bone changes, implant stability, and soft‑tissue outcomes in both immediately and delayed placed implants that were immediately loaded. 14 patients participated, with se

The injection moulding technique (IMT) offers a conservative, minimally invasive approach for dental restorations, enabling precise application of thin, flowable composite into a transparent silicone mould. Its fluid consistency allows complete adaptation to the mould and natural tooth surfaces, often avoiding the need for any tooth preparation and preserving tooth integrity. Using an etch-and-rinse protocol, IMT is highly reproducible and particularly advantageous following orthodontic treatmen

Periodontitis is a chronic inflammatory disease driven by complex interplays between a dysbiotic oral microbiome and a dysregulated host inflammatory response that results in the destruction of the tooth-supporting apparatus. Among the inflammatory cells involved in the pathogenesis of periodontitis, macrophages are recruited early on to sites of periodontal infection. These cells can polarize in different phenotypes that mediate the initiation and resolution of inflammatory responses, as well a
