Purpose: To evaluate in vitro the potential of an intraoral scanner (IOS) to monitor erosive tooth wear (ETW) using different alignment software with distinct quantitative measurement metrics.

Methods: 15 unpolished bovine crowns were exposed to citric acid (pH ~2.5) at 24-hour intervals up to 168 hours.

Efficacy of a calcium-phosphate/fluoride varnish and ionomeric sealant on cervical dentin hypersensitivity: A randomized, double-blind, placebo-controlled clinical study.

Background: Dentin hypersensitivity (DH) is a common problem in the population that can have a significant impact on the quality of life of those who suffer from the condition.

Objectives: Compare the efficacy of two treatments for DH: Ca/PO /F varnish (Clinpro White Varnish) and ionomeric sealant (IS) (Clinpro XT Varnish) with a placebo.

Methods: Participants (121) with at least one tooth with visual analogue scale (VAS) score of 4 and above were randomly and blindly allocated to the groups.

Association of Nd:YAG laser and calcium-phosphate desensitizing pastes on dentin permeability and tubule occlusion.

Objective: To evaluate the efficacy of Nd:YAG laser associated with calcium-phosphate desensitizing pastes on dentin permeability and tubule occlusion after erosive/abrasive challenges.

Methodology: Dentin specimens were exposed to 17% ethylene diamine tetra-acetic acid (EDTA) solution for 5 min and randomly allocated into five groups: G1, control (no treatment); G2, Nd:YAG laser (1 W, 10 Hz, 100 mJ, 85 J/cm2); G3, Laser + TeethmateTM Desensitizer; G4, Laser + Desensibilize Nano P; and G5, Laser+Nupro®. Specimens underwent a 5-day erosion-abrasion cycling.

Anti-erosive effect of rinsing before or after toothbrushing with a Fluoride/Stannous Ions solution: an in situ investigation: Application order of Fluoride/Tin products for erosive tooth wear.

Objective: To evaluate the impact of the application of a F/Sn-containing mouthrinse before or after toothbrushing with a F/Sn/chitosan toothpaste on the progression of erosion/abrasion on enamel and dentin.

Methods: This crossover in situ study had five arms: Control (toothbrushing without toothpaste), Brushing (toothbrushing with toothpaste), Brushing + Rinsing, Rinsing + Brushing, and Rinsing (without toothbrushing). Fifteen subjects used removable mandibular appliances containing 3 enamel and 3 dentin specimens, which were subjected to erosion-abrasion cycling of 60 min salivary pellicle formation followed by 5 min extra-oral erosion with 1% citric acid (4x/day for 5 days).

Bleaching of severely darkened nonvital tooth case report-48 months clinical control.

Objective: To record in detail, the long-term success of a bleaching treatment employing hydrogen peroxide in a severely darkened tooth.

Clinical Considerations: Tooth discoloration is an important aesthetic complain of patients. Because it is a relatively common condition, different materials and techniques capable of restoring the tooth color in a minimally invasive, conservative, and longstanding manner were developed.

Enamel surface loss after erosive and abrasive cycling with different periods of immersion in human saliva.

Objective: This in vitro study aimed to evaluate different periods of exposure to clarified human saliva for the ability to protect enamel against erosive tooth wear.

Methods: For this purpose, sixty specimens (4 × 4 × 1.5 mm) were prepared from third human molars.

Using fluoride mouthrinses before or after toothbrushing: effect on erosive tooth wear.

Objectives: 1. To evaluate the use of fluoridated mouthrinses before or after toothbrushing on erosive tooth wear. 2.

Effect of in-office desensitizers containing calcium and phosphate on dentin permeability and tubule occlusion.

Objectives: To evaluate the performance of calcium/phosphate desensitizing agents when used for dentin permeability and tubule occlusion.

Methods: 1 mm-thick dentin specimens were immersed in 17% EDTA solution and allocated into 7 groups: 1. Clinpro White Varnish, 2.

Associative Protocol for Dentin Hypersensitivity Using Nd:YAG Laser and Desensitizing Agent in Teeth with Molar-Incisor Hypomineralization.

The aim of this article was to describe and discuss a clinical case in which the Nd:YAG laser and a desensitizing agent were associated in a protocol for dentin hypersensitivity (DH) in teeth with molar-incisor hypomineralization (MIH). DH is a common condition among the population, being one of the main reasons for patients to seek for a dental treatment. MIH can be considered a condition that induces DH.

Nd:YAG laser and calcium sodium phosphosilicate prophylaxis paste in the treatment of dentin hypersensitivity: a double-blind randomized clinical study.

Aim: This double-blind, placebo-controlled, randomized clinical trial evaluated the effectiveness of Nd:YAG laser and a calcium sodium phosphosilicate-containing paste (NovaMin®) in the treatment of cervical dentin hypersensitivity (CDH).

Materials And Methods: Seventy patients were randomly allocated into the following experimental groups: control-placebo, calcium sodium phosphosilicate paste (NovaMin®), and Nd:YAG laser (1 W, 10 Hz, 85 J/cm). Pain was evaluated by means of a visual analog pain scale (VAS) after evaporative stimulation with a jet of air and tactile stimulation with an exploratory probe, before treatment (baseline) and after 5 min, 1week, and 4 weeks.

Effectiveness and acid/tooth brushing resistance of in-office desensitizing treatments-A hydraulic conductance study.

Objective: To evaluate dentin permeability and tubule occlusion of in-office desensitizing treatments, and to analyze their resistance to erosive/abrasive challenges.

Design: Ninety-one 1mm-thick dentin discs were immersed in EDTA solution for 5 min. After analyzing the maximum dentin permeability, the specimens were randomly allocated into 7 experimental groups (n = 10): Control (no treatment); Er,Cr:YSGG laser; Nd:YAG laser; Gluma Desensitizer; Duraphat; Pro-Argin toothpaste; Calcium Sodium Phosphosilicate (CSP) paste.

Is photobiomodulation (PBM) effective for the treatment of dentin hypersensitivity? A systematic review.

The present study aims to evaluate the current scientific data regarding the effectiveness of photobiomodulation (PBM) in the treatment of dentin hypersensitivity (DH) as an alternative method for pain control. A systematic review was conducted to assess the effectiveness of PBM as treatment for DH. A complete literature search was performed up to October 2016.
