This study compared several techniques of manual and power instrument supragingival scaling and subsequent polishing with different methods. Observations were made to determine if there was an optimal method of enamel surface treatment based on the efficacy of the polishing and damage to the enamel. The maxillary fourth premolar and canine teeth were used as experimental teeth. These teeth were extracted after treatment and immersed in 10% buffered formalin solution for further processing and evaluation using electron microscopy. Our observations indicated that the most effective method for scaling and enamel protection during periodontal treatment was provided by power instrumentation followed by polishing using a soft polishing wheel with pumice paste.

Effect of polishing on the morphology of Zircaloy-4 nanostructure: formation of a novel hexagonal nanoscale pattern.

Zircaloy-4 (Zr-4) is widely used as the cladding material in nuclear power plants (NPPs) due to its excellent corrosion resistance and low neutron absorption cross-section. Under Loss of Coolant Accident (LOCA) conditions, oxidation of Zr-4 can compromise the safety of the NPPs by accelerating hydrogen production. Therefore, enhancing the oxidation resistance of Zr-4 is a critical research focus.

Chlorhexidine (CHX) is the most commonly used mouthwash with proven antiplaque and antibacterial activity. The aim is to evaluate the effect of vitamin C (VitC) in CHX mouthwash on plaque accumulation and gingivitis, and to compare it with CHX alone mouthwash and antiseptic phenol-containing mouthwashes. This study conducted as a multicenter, randomized, controlled, double-blind, parallel design clinical study.

Dental ultrasonic scalers are commonly employed in periodontal treatment; however, their ability to roughen tooth surfaces is a worry since roughness may increase plaque production, a key cause of periodontal disease. This research studied the influence of a piezoelectric ultrasonic scaler on the roughness of two distinct flowable composite filling materials. To do this, 10 disc-shaped samples were generated from each of the two flowable composite materials.

To address this issue, this paper presents a method based on stereo deflectometry for measuring the figure of the off-axis aspheric mirror. In this method, point cloud of the off-axis aspheric mirror is first obtained using stereo deflectometry.

Background: In this study, we estimated the risk of surgically treated postoperative periprosthetic femoral fractures (POPFFs) associated with femoral implants frequently used for total hip arthroplasty (THA).
Methods: In this cohort study of patients who underwent primary THA in England between January 1, 2004, and December 31, 2020, POPFFs were identified from prospectively collected revision records and national hospital records. POPFF incidence rates, adjusting for potential confounders, were estimated for common stems.
