Effectiveness of fluoride-containing toothpastes associated with different technologies to remineralize enamel after pH cycling: an in vitro study.

Background: To evaluate the efficacy of fluoride-containing toothpastes with different technologies to remineralize artificial caries lesions in enamel.

Methods: Bovine enamel blocks were divided into three thirds: intact (untreated), demineralized (artificial caries lesion), and treated (caries lesion, pH cycling with dentifrices). Enamel blocks were randomly distributed into five groups (n = 12): Fluoride-free toothpaste, Colgate Oral Care (NC); Arginine-containing toothpaste, Colgate Total Daily Repair (PC); Silicate-based fluoride toothpaste: REFIX technology, regenerador + sensitive (RDC), NR-5 technology, Regenerate Enamel Science (RES), and NOVAMIN technology, Sensodyne Repair and Protect (SRP).

Influence of energy drinks on enamel erosion: study using different assessment techniques.

Background: Dental erosion has become a relevant public health problem in recent years and is related to the increase in the consumption of acidic beverages. Objective: The aim of the present study was to evaluate the erosive potential of energy drinks on dental enamel using an in vitro erosion model.

Material And Methods: Thirty-eight blocks of human enamel were divided into four groups: G1- TNT Energy Drink®(n=8), G2- Red Bull® (n=10), G3- Monster Energy® (n=10), and G4- Coca-Cola® (n=10) (positive control).

Erosive effect of industrialized fruit juices exposure in enamel and dentine substrates: An study.

Background: Erosive tooth wear has been a highly prevalent and emerging phenomenon related to eating habits of the population. Aim: This study sought to investigate industrialized fruit juices exposure in enamel and dentine substrates in terms of erosive effect.

Material And Methods: Human enamel and dentine specimens were randomized into 8 groups (n=8): Grape juice - Ades®, Grape juice - Del Valle Kapo®, Grape juice - Aurora®, Orange juice - Del Valle Kapo®, Orange juice - Ades®, Strawberry juice - Mais Vita®, Strawberry juice - Ades®, Citrus fruit juice - Tampico®.

Nanoencapsulated fluoride as a remineralization option for dental erosion: an study.

Objective: To compare the performance of different dentifrices indicated for dental erosion and a new dentifrice with controlled fluoride release system (NanoF) in terms of surface microhardness remineralization in enamel erosion lesions.

Materials And Methods: 72 human enamel specimens were divided into 6 groups ( = 12): PC (100% NaF - positive control); NC (Placebo - negative control); 50%nF (50% NanoF + 50% free NaF), 100%nF (100% NanoF); PN (Sensodyne ProNamel™) and AG (Colgate Sensitive Pro-Relief™). A surface microhardness analysis was performed before (SH) and after (SH) the erosion lesion formation.

Allium sativum Compared to Cilostazol as an Inhibitor of Myointimal Hyperplasia.

Objective: Intimal hyperplasia is associated with graft failure and vascular sutures in the first year after surgery and in postangioplasty restenosis. Allium sativum (common garlic) lowers cholesterol and has antioxidant effects; it also has antiplatelet and antitumor properties and, therefore, has great potential to reduce or inhibit intimal hyperplasia of the arteries. Our objective is to determine if the garlic has an efficacy to inhibit myointimal hyperplasia compared to cilostazol.

In situ effect of a CPP-ACP chewing gum on enamel erosion associated or not with abrasion.

Objectives: The purpose of this study is to analyze the in situ effect of a casein phosphopeptide-stabilized amorphous calcium phosphate (CPP-ACP) chewing gum on human enamel erosion lesion associated or not with abrasion.

Material And Methods: A three-way crossover study of 7 days was conducted involving 10 volunteers subjected to the same protocol: (G1) CPP-ACP sugar-free chewing gum, (G2) regular sugar-free chewing gum without CPP-ACP, and (G3) saliva-no chewing gum. An abrasion test was included in each phase.

Facial growth evaluation of complete unilateral cleft lip and palate operated patients: a cleft reference center in Paraíba, Brazil, using the "GOSLON" yardstick.

Objectives: To evaluate the surgical outcomes of patients with complete unilateral cleft lip and palate (CUCLP) operated on by a single surgeon of the cleft reference center of the Lauro Wanderley University Hospital at the Federal University of Paraiba.

Methods: Forty-four individuals' dental casts diagnosed with CUCLP, born between 1995 and 2002, mean age of 11 years, were evaluated by three calibrated orthodontic specialists and scored by the Great Ormond Street, London and Oslo (GOSLON) yardstick on two occasions. The scores were compared with those observed in other centers around the world.

Evaluation of different methods for monitoring incipient carious lesions in smooth surfaces under fluoride varnish therapy.

Background: There are only a few studies relating visual inspection methods and laser fluorescence when monitoring regression of incipient carious lesions.

Aim: The purpose of this study was to monitor incipient carious lesions in smooth surfaces under varnish fluoride therapy using visual inspection methods and laser fluorescence (LF).

Design: Active white spot lesions (n = 111) in upper front teeth of 36 children were selected.
