Evaluation of the Periotest Method in Dental Traumatology
Summary
Background/Aims: The Periotest® method represents a technique for objective tooth mobility assessment. The aims of this study were: 1. receiving information about normal Periotest® values in vertical and horizontal dimension on periodontally healthy teeth for individuals aged 20-35, 2. investigating the reliability of the Periotest® method in terms of intra-serial and inter-serial reproducibility before splinting and with an applied dental trauma splint, 3. evaluating the splint effect of two different wire-composite splints in vivo.
Materials and Methods: On periodontally healthy dental students (n=33; mean age 24.7 years) Periotest® values were measured on reproducible measuring points, in vertical and horizontal dimension and before splinting and after splint insertion. Three readings were taken per serial to observe the intra-serial reproducibility, and for testing inter-serial reproducibility three serials were measured (Friedman-test; P ≤ 0.001). Two different wire-composite-splints (1 = Dentaflex 0.45 mm, 2 = Strengtheners 0.8x1.8) were inserted, the Periotest® values were measured and the splint effects were calculated and compared (Whitney-Mann-U-test; P ≤ 0.001).

Medical and Biotech [MESH] Definitions
Orthodontic Brackets
Small metal or ceramic attachments used to fasten an arch wire. These attachments are soldered or welded to an orthodontic band or cemented directly onto the teeth. Bowles brackets, edgewise brackets, multiphase brackets, ribbon arch brackets, twin-wire brackets, and universal brackets are all types of orthodontic brackets.
Composite Resins
Synthetic resins, containing an inert filler, that are widely used in dentistry.
Dental Cements
Substances used to bond COMPOSITE RESINS to DENTAL ENAMEL and DENTIN. These bonding or luting agents are used in restorative dentistry, ROOT CANAL THERAPY; PROSTHODONTICS; and ORTHODONTICS.
Jaw Fixation Techniques
The stable placement of surgically induced fractures of the mandible or maxilla through the use of elastics, wire ligatures, arch bars, or other splints. It is used often in the cosmetic surgery of retrognathism and prognathism. (From Dorland, 28th ed, p636)
Electrocoagulation
Procedures using an electrically heated wire or scalpel to treat hemorrhage (e.g., bleeding ulcers) and to ablate tumors, mucosal lesions, and refractory arrhythmias. It is different from ELECTROSURGERY which is used more for cutting tissue than destroying and in which the patient is part of the electric circuit.
Clinical Trials
Evaluation of Cork Splint Materials Instead of Plaster Splint for Children
This is an evaluation of the functionality and added value of cork splint materials instead of a plaster splint for children (3-11 years old).
Functional Splint for Osteoarthritis of the Trapeziometacarpal Joint
Forty participants were enrolled in a randomized, controlled clinical trial to evaluate the effectiveness of a functional thumb splint for trapeziometacarpal OA in the dominant hand.
Cast Versus Splint in Children With Acceptably Angulated Wrist Fractures
The study will compare the effectiveness of a prefabricated wrist splint with thermoplast reinforcements versus a short arm cast in skeletally immature children. The hypothesis is that th...
