For each type wire, four samples analyzed as received after 1 month clinical use by an atomic force microscope (AFM) a scanning electronic (SEM). sliding resistance, two stainless steel plates with three metallic or monocrystalline...

Structured Abstract Objectives The efficacy of functional appliances remains highly debated. This randomized controlled trial investigated the skeletal and dentoalveolar effects determined by Sander bite‐jumping appliance ( BJA ). null hypothesis to be tested was that would not induce supplementary mandibular growth compared untreated controls. Setting Sample Population study carried out at Section Orthodontics, University Naples Federico II , Italy. Forty‐six patients receiving a clinical...

ABSTRACT Objective This retrospective study aims to assess the predictability of Overbite (OVB) reduction and Curve Spee (COS) levelling in patients with deep bite malocclusion treated Clear Aligner Therapy (CAT). The research evaluates accuracy prescribed movements growing non‐growing patients. Materials Methods Thirty‐six Invisalign from January 2018 using SmartTrack were included. Digital models at pre‐treatment, virtual plan post‐treatment phases collected analysed Geomagic Control X....

Background/Objectives: Condylectomy is a delicate and intricate procedure commonly employed in the management of temporomandibular joint (TMJ) disorders, osteochondromas, condylar hyperplasia, hemimandibular other pathologies affecting region. The advent surgical cutting guides has introduced new dimension to condylectomy procedures as they enable surgeons plan execute precise cuts with heightened level accuracy. In literature already exists cases guide-based condylectomy, but only depend on...

Background/Objectives: Parents/caregivers’ reports are valuable because they frequently play a crucial role in making decisions concerning child’s health, and their perspectives can significantly impact treatment choices. Furthermore, negative effects of oral health issues extend beyond just the adolescent patient, having an on family life. The aim this study is to explore perception parents/caregivers regarding children’s oral-health-related quality life (OHRQoL) how OHRQoL adolescents...

Our goal was to characterize the response of human mesenchymal stem cells (hMSCs) a novel composite scaffold for bone tissue engineering. The hydroxyapatite–polycaprolactone (HA–PCL) scaffolds were prepared by sol–gel method at room temperature and morphology investigated scanning electron microscopy (SEM)/energy-dispersive spectroscopy (EDS) validate synthesis process. two different lines hMSCs, bone-marrow-derived (BMSCs) dental pulp (DPSCs) in terms cell proliferation differentiation into...

Objective: Metal alloys used in dentistry and other biomedical fields may release nickel ions the oral environment. The of might influence normal biological physiological processes, including tissue wound healing, cell growth proliferation. aim this study was to evaluate vitro effects on cycle, viability Materials Methods: Human osteosarcoma cells (U2OS) human keratinocytes (HaCat) were exposed different chloride (NiCl 2 ) concentrations (0 - 5mM) for various periods exposure. cultured...

Although the clinical use of miniscrews has been investigated on a large scale, little is known about their biocompatibility. Since low pH can affect corrosion resistance, aim this study was to evaluate cytotoxic effect orthodontic in different conditions.Four stainless steel and grade IV V titanium were immersed 7 4 saline solution for 1, 7, 14, 21, 28, 84 days. Human osteogenic sarcoma cells (U2OS), permanent human keratinocytes (HaCat), primary gingival fibroblasts (HGF) exposed eluates,...

ABSTRACT Objective: To investigate the cytotoxicity of nickel-titanium (NiTi) esthetic orthodontic archwires with different surface coatings. Materials and Methods: Three fully coated, tooth-colored NiTi wires (BioCosmetic, Titanol Cosmetic, EverWhite), two ion-implanted (TMA Purple, Sentalloy High Aesthetic), five uncoated (BioStarter, BioTorque, Superelastic, Memory Wire Sentalloy), one β-titanium wire (TMA), stainless steel (Stainless Steel) were considered for this study.
