Abstract:
Pain measurements help to determine the severity, type and duration of pain and are used to make an accurate diagnosis and evaluate the effectiveness of treatment. Pain relief can be achieved pharmacologically or non pharmacologically. Pharmacologically, NSAIDs are the drugs of choice. They act by inhibition of enzyme cyclooxygenase which mediates the transformation of prostaglandins from arachidonic acid in the cellular plasma membrane. PGs such as PGE and PGE2 are important mediators of bone resorption. COX – 1 is considered important in tissue homeostasis. COX – 2 is transcripti

Background context. Dental implants are designed to replace a missing tooth. Implant stability is vital to achieving osseointegration and successful implantation. Although there are many implants available on the market, there is room for improvement. Purpose. We describe a new dental implant with improved primary stability features. Study design. Lab bench test studies. Methods. We evaluated the new implant using static and flexion–compression fatigue tests with compression loads, 35 Ncm tightening torque, displacement control, 0.01 mm/s actuator movement speed, and 9–10 Hz load application f

Introduction There are many orthodontic simulators known as Typodonts used since 1981. We use in daily practice electrodonts by Savaria-Dent Kft (Szombatheley, Hungary), a laboratory device, which simulates the orthodontic movements. The electrodonts were created by setting the teethes in a silicone mould filled with dual consistency wax. Every tooth is wrapped in coper coil and continuous electric current is injected, heating the wax generating orthodontic movement under the action of orthodontic wires. This device comes with a time regulator and the amperage is limited to 2 Amps. The electro

Abstract:
Orthodontically induced inflammatory root resorption (OIIRR) is inevitable as the force applied during orthodontic treatment to initiate tooth movement induces inflammation, causing iatrogenic root resorption. Even with the use of new technologies in orthodontic appliances, the traumatic effects on the periodontium are still present. Therefore, a proper understanding of the biological aspect of OIIRR such as its pathophysiology and the repair process is crucial to aid in its prevention or minimizing the damage to the apical region.

Abstract:
Bruxism is known as the rhythmical clenching of the lower jaw (mandibular) by the contraction of the masticatory muscles and parafunctional grinding of the teeth. It affects patients’ quality of life adversely due to tooth wear, pain, and fatigue in the jaw muscles. Recently, effective diagnosis methods that use electromyography, electrocardiography, and electroencephalography have been developed for bruxism. However, these methods are not economical since they require specialization and can be performed in clinical conditions. Although using surface electromyography signals alone is an econom

This article reviews the evolution of concepts regarding the biological foundation of force-induced tooth movement. Nineteenth century hypotheses proposed two mechanisms: application of pressure and tension to the periodontal ligament (PDL), and bending of the alveolar bone. Histologic investigations in the early and middle years of the 20th century revealed that both phenomena actually occur concomitantly, and that cells, as well as extracellular components of the PDL and alveolar bone, participate in the response to applied mechanical forces, which ultimately results in remodeling activities

Finding the greatest way to maximize tooth motion with the least drawbacks is now more important than ever.
