Comparative Evaluation of Two Novel Natural Desensitizing Agents on Dentinal Tubule Occlusion: A Scanning Electron Microscopy Study.

Aim: The present study is aimed to compare the effectiveness of dentinal tubule occlusion of two natural-based desensitizing toothpaste (Bentodent Desensitizer and Fang Farm Mint) and Novamin-based toothpaste (Shy-NM) under scanning electron microscope (SEM).

Materials And Methods: A total of 60 root dentin discs (3 mm-thick) were obtained from recently extracted permanent premolar teeth and were randomly divided into four groups based on the desensitizing toothpaste used, each group with 15 samples: Group I: Control, group II: Shy-NM, group III: Bentodent desensitizer, group IV: Fang Farm Mint. Samples were brushed for 2 min twice daily with a soft toothbrush with respective pea size amount of toothpaste for 14 days manually.

The efficacy of lining materials in the reduction of microleakage in class II composite resin restoration using the sandwich technique: A stereomicroscopic study.

Background: The sealing ability of different liners under composite restorations in the reduction of microleakage.

Aim: To evaluate the effects of three different liners in sandwich techniques on gingival microleakage of class II composite restorations.

Materials And Methods: Standardized Class II box cavities were prepared on forty premolar teeth and randomly divided into four groups, = 10: Group A, no liner (control); Group B, Polofil NHT Flow; Group C, Ionolux; and Group D, Fuji VII.

Comparison of the effectiveness of three different desensitizing toothpastes in reducing dentin hypersensitivity: A 4-week clinical study.

Aim: To compare the effectiveness of three different desensitizing toothpastes containing potassium salt, natural ingredients, and 8% arginine in reducing dentin hypersensitivity (DH).

Materials And Methods: A 4-week study was conducted on 45 adult patients suffering from hypersensitivity associated with cervical abrasion of two or more teeth anterior to the molars. Patients were divided into three toothpaste groups as follows: Group I: potassium salt, Group II: herbal desensitizing paste containing natural ingredients, and Group III: 8% arginine.

Rotary science and its impact on instrument separation: A focused review.

Efficient endodontic treatment demands thorough debridement of the root canal system with minimal procedural errors. The inherent weakness of nickel-titanium alloys is their unexpected breakage. Modifications in the design, manufacturing, thermomechanical and surface treatment of alloys and advancements in movement kinetics have shown to improve the fatigue properties of the alloys, reducing the incidence of separation.

Comparative Evaluation of Cleaning Efficacy using Four Novel Nickel-titanium Rotary Instruments: An in vitro Scanning Electron Microscope Study.

Aim: The aim of the study was to compare the cleaning efficacy (debris and smear layer removal) of two multifile rotary systems (MTwo and Silk) and two single-file rotary systems (F6 Skytaper and NeoNiTi).

Materials And Methods: Eighty mesial canals of mandibular first molars were cleaned and shaped using four nickel-titanium (NiTi) rotary instruments to size # 25 and 3% NaOCl and 17% ethylenediaminetetraacetic acid (EDTA). Samples were randomly divided into four equal groups (n = 20) according to instrumentation: Group I, Mtwo; group II, Silk; group III, F6 Skytaper; group IV, NeoNiTi.
