ABSTRACT
Situs inversus totalis (SIT) has been reported as a rare entity. It may elude routine patient evaluation, detailed knowledge about the normal anatomical structure and its variations must be known for daily clinical practice and even more critical in an emergency. SIT is inherited as an autosomal recessive pattern and is associated with multiple gene mutations. Situs inversus totalis is a condition that is characterized by abnormal positioning of the heart and other internal organs. It may or may not be associated with other congenital defects. Diagnosis of situs inversus totalis is an important in a patient who does not have any congenital anomalies, which may indicate a normal life expectancy, the patient’spresentation of common ailments may become difficult to diagnose due to mirrored anatomy. Here we report the full mouth rehabilitation in a case of situs inversus totalis.

ABSTRACT
Tooth loss is, for the majority of patients, a strong physical and psychological disorder. The objective of this study was to evaluate the individual perception of dental aesthetics among patients received for joint prosthetic rehabilitation in the prosthesis department of the CHU-OS of Bamako. This was an epidemiological, descriptive and prospective study. The survey lasted 5 months, from April to August 2013. The population studied is made up of all the people seen in the prosthesis department. The variables studied were socio-demographic (sex, age) and clinical variables (reason for consultation, color, shape and position of teeth, personal appreciation of aesthetics, smile identification, patient satisfaction). The data obtained were entered and analyzed with SPSS version 20 software and processed with Word 2013 software. We examined 218 patients and the distribution according to sex showed a predominance of women with 67% with a sex ratio of 0.49. The study highlighted the youth of our population with 34.86% of people who are between 25 and 34 years old. In this study, white and well-positioned teeth are the dental aesthetic criteria most sought after by patients with respectively 91.3% and 54.6% of cases considering the position of the tooth always in association with the color as an important element in the aesthetics of a smile. The disability of edentulism opens up a psychological dimension that the practitioner must understand. It is a global care of the patient with his doubts and anxieties.

ABSTRACT
Background: Ankyloglossia “tie tongue” is a congenital anomaly, characterized by abnormal short thick lingual frenum that causes limitation of tongue movement, which results in problems in speech, mastication and patient discomfort. Laser is an alternative for conventional surgery to treat ankyloglossia. Case Report: A 50 years old female patient presented with ankyloglossia to laser clinic in faculty of Dentistry in Misr University for Science and Technology. Lingual frenectomy was done with Diode Laser with 980 nm wavelength, fiber tip diameter 300 μm, power 1.5 Watt, continuous wave mode and contact mode. The time of procedure was only 15 minutes, with bloodless field during work. Patient dismissed without sutures or wound dressing. Results: There was no post-operative pain, discomfort or swelling. Complete healing occurred after 2 weeks. The patient was very satisfied with the quick painless procedure. Conclusion: Diode Laser 980nm treatment of Ankyloglossia is a simple, quick, painless and safe, and effective procedure. We recommend this treatment modality because of its advantages for both the patient and the operator.

ABSTRACT
Еndodontic irrigants could alter the mechanical properties of root canal dentin. The aim of the current study was tо compare the effect of three irrigation protocols on root canal dentin microhardness and roughness with respect to their concentration and additional ultrasonic activation for the same treatment period. Forty single-rooted, intact upper incisors were decoronated and sectioned longitudinally in buccolingual direction. The surfaces of all eighty samples were polished and randomly allocated into four equal groups (n=20): Group 1: Control group (distilled water); Group 2: 2% NaOCl/2 min followed by 17% EDTA/2 min; Group 3: 2% NaOCl/2 min followed by 17% EDTA/2 min, both ultrasonically activated Group 4: 5.25% NaOCl/2 min followed by 17% EDTA/2 min. Root dentin microhardness was significantly lowered by all of the irrigants regardless of their concentration and/or additional agitation (p<0.05). The surface of root canal dentin was roughned to the greatest extent by the ultrasonically activated irrigation solutions (p<0.001). The ultrasonic activation of the disinfection solutions significantly altered the biomechanical properties of dentin.
