Abstract: La neurofibromatose type 1 est une maladie génétique causée par un défaut d'un seul gène codant pour la neurofibromine, une protéine cytoplasmique impliquée dans le contrôle du cycle cellulaire. L'oeil est fréquemment affecté dans la neurofibromatose, et par conséquent les manifestations oculaires jouent un rôle majeur dans le diagnostic de la NF. Ce cas clinique rare soulève l'importance de l'examen ophtalmologique chez ces patients en décrivant les manifestations oculaires trouvées dans la neurofibromatose notamment des paupières, de la cornée et l'iris mais aussi le nerf optique.

Abstract: Le mélanocytome est une forme distincte de naevus qui se localise souvent sur la papille, mais qui peut également concerner le tractus uvéal ou la rétine sensorielle. Il est très important de différencier les lésions bénignes du mélanome malin. Il se reconnaît par son aspect typique avec une pigmentation intense occupant tout ou juste une partie du disque optique avec une extension en surface ou en profondeur ou tout autour. Il est souvent stable, sans tendance à se compliquer. Mais il est important de savoir que dans 10 à 15% des cas, le ménalocytome du disque optique peut provoquer une baisse de l'acuité visuelle qui est souvent le motif..........

Abstract:Objectives: To evaluate and compare translucency of Zirconia reinforced lithium silicate and lithium disilicate. Zirconia reinforced lithium silicate glass ceramic has been introduced to the dental market for dental CAD/CAM applications. Lithium disilicate glass ceramic has more favourable mechanical properties compared with conventional dental porcelains and has excellent optical properties. Materials and Methods: The translucency of the specimens placed on white or black backings was measured with a reflection spectrophotometer (Color Eye 7000A, Xrite; GretagMacbeth) in the wavelength range of 400 to 700 nm with 10-nm data intervals.

Abstract: Introduction: Finding a complete human skeleton at a disaster site is statistically less likely than finding broken bone fragments. These factors increase the possibility of incorrect sex determination. Aim: The aim of the present study is as skeletal characteristics vary by population, we attempted to determine the sex using significant parameters in the mandibular length, mandibular index, and body thickness of the mandible in the population of Indore region. Materials & methods: Prior to starting, the study received approval from the institutional ethics committee. The Department of Anatomy's initiative is located at the Index Medical College and Hospital in Indore, India's Madhya Pradesh state. jawbones from dried humans, unknown in gender........

Abstract: The use of low level lasers have been increasingly advancing in the recent years. Low level laser therapy seems to have promising results in areas like wound healing, pain management, tissue stimulation, cell proliferation, differentiation and control of inflammation. Anti-microbial photodynamic therapy also helps in reducing the bacterial contamination. The future of LLLT depends on the correlation of technological innovations with clinical application.

Abstract: Background: Porcelain fused to metal crown prosthesis has a combined effect of fracture resistance of metal substructure and esthetic property of porcelain. The bonding ability of porcelain to metal affects the long-term reliability of porcelain fused to metal restorations. New technologies have led to introduction of new materials, so an evaluation of the adhesion of porcelain to these material is needed. Materials and Methods: Total 30 discs 10 discs each of cobalt chromium were fabricated by conventional lost wax technique (casting) and two CAD/CAM systems by subtraction (direct milling) and addition (laser sintering) which were later fired with a popular commercial porcelain system.........

Abstract: Artificial intelligence (AI) has shown great potential in the field of dentistry. One of its most useful applications is in diagnostics, where AI algorithms can analyze dental images and identify dental conditions at an earlier stage. This can help dentists provide more effective treatments and improve patient outcomes. Additionally, AI can be used for predictive analytics to identify patients at risk of developing dental problems and provide preventive care. Chatbots and virtual assistants powered by AI can improve patient engagement and satisfaction by providing information and answering common dental questions. Finally, robotics can assist in complex dental procedures, such as dental implant placement, making them more accurate and efficient. Overall, AI has the potential to revolutionize dentistry and improve patient care.

Abstract: Photogrammetry is a powerful tool in implantology that can improve the accuracy and efficiency of implant placement. By creating accurate 3D models of a patient's mouth and teeth, dentists can plan implant placement with a high degree of precision and ensure better outcomes for patients. As technology continues to advance, we can expect to see even more applications of photogrammetry in the field of dentistry, leading to better outcomes and a more comfortable experience for patients. Photogrammetry technology has become increasingly popular in implant dentistry due to its non-invasive nature and ability to produce accurate 3D models of the oral cavity.......

Abstract: Introduction: A surgical incision acts as an aperture into the body to permit the work of the operation to proceed. As majority of the surgeries performed by the general surgeons take place within the abdominal cavity and hence laparotomy is one of the most common procedure performed in emergency as well as elective settings. So, incision and closure occupies the most important aspect in the abdominal surgery. The aim of this study was to compare the benefits of interrupted and continuous closure of abdominal fascia in midline laparotomy wound and complications like seroma formation, wound gaping, burst abdomen and incisional hernia in both types of closures......
