Effect of Various Vital Bleaching Systems on Clinical Outcomes and Patient Satisfaction.

Objective To evaluate the clinical behavior of different bleaching products - the hydrogen peroxide (HO), carbamide peroxide (CP), and titanium dioxide bleaching systems. Methods Three bleaching systems with different concentrations (HO 15%, 38%, CP 15%, 35%, and titanium dioxide 20% HO) were used. Sixty participants with discolored teeth were enrolled and equally divided into six groups.

Effectiveness of Different Rotary Files Systems in Removal of Gutta-percha during Endodontic Retreatment with or without Solvents: A Comparative Study.

Aim: The purpose of the present study was to compare the efficacy of three different file systems in removing gutta-percha during endodontic retreatment with or without solvents.

Materials And Methods: The current study used 120 freshly extracted, single-rooted human mandibular premolars extracted for orthodontic procedures. The canal was prepared utilizing the step-back technique and obturation was done.

Comparison of the Fracture Resistance of Root-Canal-Treated Premolars Obturated With Dissimilar Materials: An In Vitro Study.

Introduction The utilization of endodontic sealers is of paramount importance in ensuring the sustained efficacy and resilience of endodontic treatment. The primary objective of the research was to appraise and contrast the fracture resistance (FR) of three distinct categories of endodontic sealing materials that are frequently employed in the context of endodontic therapy. Materials and methods This research used an in vitro experimental design.

Dentists' Utilization of Caries Risk Assessment and Individualized Caries Prevention Methods in Pediatric Patients in Saudi Arabia.

Introduction: The first step in any complete oral health care plan for a child is a thorough caries risk assessment (CRA). This study aimed to investigate whether the practice dentists in Saudi Arabia's Western province do CRA methods and offer Individualized Caries Prevention (ICP) to their pediatric patients.

Material And Methods: Dentists in active clinical practice in the Western province of Saudi Arabia were the participants of this cross-sectional survey.

Dental Students' Ability to Detect Only-Enamel Proximal Caries on Bitewing Radiographs.

Introduction The dental students are trained to identify the proximal carious lesion using clinical tools and radiography over three years of academic curriculum. During these years the students are expected to learn detection of incipient carious lesions and take appropriate preventive/restorative measure. Method This study aimed at evaluating the ability of the students and interns to detect only-enamel proximal caries on the five digital bitewing radiographs.

Complementary and Alternative Medicines in Oral Health Care: An Integrative Review.

Complementary and alternative medicine (CAM) uses a holistic approach that finds natural solutions that help the immune system to fight off infection and diseases. In conventional medicine, the diseases are treated as a series of symptoms developed and not its actual cause or etiology, but CAM commonly targets the exact cause of the disorder thereby stimulating the body's healing process. This is based on an integrative literature review of methods and techniques used as complementary and alternative approaches for oral health care.

FPGA Realizations of Chaotic Epidemic and Disease Models Including Covid-19.

The spread of epidemics and diseases is known to exhibit chaotic dynamics; a fact confirmed by many developed mathematical models. However, to the best of our knowledge, no attempt to realize any of these chaotic models in analog or digital electronic form has been reported in the literature. In this work, we report on the efficient FPGA implementations of three different virus spreading models and one disease progress model.

Growth Behavior of Probiotic 01 in Tiger Nut Milk Prepared with Milk By-Products.

<b>Background and Objective:</b> Different researches have been achieved on non-dairy products as an alternative to dairy products. The interest in tiger nut tubers has considerably increase in recent years due to its nutritional and health benefits. Fermented drinks of non-dairy origin play an important role in diets worldwide.

Microbial synthesis of 3-deoxy-D-erythro-hex-2-ulosonic acid 6-phosphate.

A microbial route was explored for the synthesis of 3-deoxy-D-erythro-hex-2-ulosonic acid 6-phosphate (2-keto-3-deoxy-6-phosphogluconate, KDPG). Two strains of bacteria, Alcaligenes eutrophus H16 F34 (DSM 529) and Escherichia coli DF 71 (CGSC 4880), lacking in KDPG-aldolase activity were tested for excretion of KDPG. Using pyruvate and gluconate as carbon sources, Alcaligenes eutrophus H16 F34 accumulated and excreted 3-deoxy-D-erythro-hexulosonic acid 6-phosphate into the culture broth, while the E.
