Introduction

Aphthous ulcers or recurrent aphthous ulcer (RAU) or canker sores are probably the most common1 and affect 5 to 25% of the population worldwide.2-4 The term aphthous is defined as a breach in the oral epithelium which typically exposes nerve endings in the underlying lamina propria resulting in pain and soreness.5-6 Clinically, aphthous ulcer is characterized by shallow round or oval shape7 with a white-yellow base which is a fibrinous slough,8 a discretely elevated yellowish edge9 and a distinct irregular border with a narrow red halo. Their etiology and pathogenesis are still unclear and much discussed.10 Several factors are suspected including immunological disorders,1,5 genetics, h…

Effect of Fluoride-Based Prophylactic Agents on Titanium Corrosion: A Literature Review and Clinical Implications

Dr. Wiam El Ghoul Dr. Mireille Rahi Dr. Elias Smaira Pr. Khaldoun Rifai

Abstract
Titanium is known to possess excellent biocompatibility as a result of corrosion resistance and lack of allergenicity when compared with many other metals. Fluoride is well known as a specific and effective caries prophylactic agent and its systematic application has been recommended widely over recent decades. Nevertheless, high fluoride concentrations impair corrosion resistance of titanium. The purpose of this paper is to discuss the current data regarding the influence of fluoride on titanium corrosion process in the last years. These data demonstrate noxious effects induced by high fluoride concentration as well as low PH in the oral cavity. Therefore, such conditions should be considered when prophylactic treatment is indicated with patients having dental implants or other dental devices.

Dr. Pablo Echarri


Abstract
In this article, different CA® CLEAR-ALIGNER therapeutic possibilities are demonstrated through the case reports presentation.
Keywords CA® CLEAR-ALIGNER. Therapeutic possibilities.

Introduction
Definition The CA® CLEAR-ALIGNER technique is an orthodontic treatment whose appliances consist of transparent, esthetic, comfortable, effective, progressive and sequential aligners. It allows the treatment of many patients who don’t want to wear fixed appliances. Normally, the CA® CLEAR-ALIGNER is used in adult patients, but it also can be used in mixed dentition.
Characteristics - Three different  aligners which vary in thickness are used: CA®-soft, CA®-medium and CA®-hard. - It is made step by step and one at the time with each impression. It is sequential. According to our experience and depending on the characteristics of the case or circumstances of a patient (if a patient is able to attend the appointments at the dental office, if he is on a holiday, traveling, etc.), 2 …
