Successfully Treatment of Dental Fluorosis using the Simple Technique of Enamel Microabrasion

Dental dyschromias have several origins among them we cite fluorosis. Dental fluorosis is defined as a qualitative anomaly of the enamel, resulting histologically in hypomineralisation due to excessive ingestion of fluorides during amelogenesis. Clinically, it takes the form of opacities in the enamel. These opacities may affect homologous teeth symmetrically, and generally affect several groups of teeth. Topographically, isolated or confluent white lines or discrete white patches are observed. Interpretismatic spaces are wider, resulting in porous and permeable enamel. On the one hand, this explains the post-eruptive dyschromias, where exogenous pigments penetrate the pores and transform the white opacities into brown. It is classified into 3 categories: mild, moderate and severe. So that this case was moderate fluorosis and appropriated for the treatment with enamel microabrasion. Differential diagnosis for this condition includes: enamel hypoplasia, amoelogenesis imperfecta, and dental caries.

Does Pre-Workout Supplement Consumption Affect Enamel Microhardness?

The aim of this study was to compare in vitro the micro hardness of enamel exposed to the erosive effects of three pre-workout drinks. Forty blocks (4mmx4mm) of bovine enamel were randomly selected and divided among the following pre-workout drinks (n=10): G1: Universal Shock Therapy®, G2: 1.M.R Vortex™, G3: Jack3Dmicro™, G4: Control (distilled water). The enamel microhardness was evaluated before (T1) and after (T2) the in vitro erosive test (5 min/3 times/5 days) using a Vickers digital microduremeter (load 100g/penetration 15s). The data was analyzed using descriptive statistics (mean, ±sd) and for comparison testing, using the Kruskall Wallis test and the t Student test (p≤ 0.05). All groups showed a reduction in micro hardness after the erosive test (p =0.001).1.M.R Vortex™ drink showed a large decrease in micro hardness (%SMH:34,92%). Pre-workout drinks significantly decreased the superficial micro hardness of enamel

Evaluation of Pumice, Fissure Enameloplasty, Dentin Adhesive and Air Abrasion on Sealant Microleakage

By (1995), Siegel stated that sealants are an important dental caries prevention technology, ideally used in combination with patient education, effective personal oral hygiene, fluorides, regular dental visits. There is a growing need to seal primary molars, as demonstrated by Head Start’s report that found that, for those children who had dental caries, 86% had caries of the pits and fissures of the molars.

Feasibility Analysis of Autogenous Tooth-based Bone Graft Material after Guided Bone Regeneration Technique

We set out to determine the possibility of radiographically evaluating the degree of marginal bone loss in humans after functional loading of implants at sites of guided bone regeneration (GBR) with autogenous tooth-based bone graft (ATBBG) material (AutoBT®, Korea Tooth Bank, Seoul, Korea).

Legal Medical Age Estimation in Portuguese Adult Cadavers: Evaluation of the Accuracy of Forensic Dental Invasive and Non-Invasive Methods

Age estimation of unknown human cadavers is important in setting a crime investigation, such as homicide, suicide or in mass disaster because it can guide forensic investigators to the correct identity among a large number of possible matches. More and more the courts ask for medico-legal age estimations of unknown human cadavers by forensic dentistry.
