Abstract: Immune thrombocytopenia (ITP) is an autoimmune disease defined as decreased platelet count which is caused by antiplatelet autoantibodies. Here we present a case of elderly patient who exhibited petechiae in oral mucosa and forearm which was found by the dentist and subsequently diagnosed as ITP by the hematologist. An 89-year-old male who had a chief complaint of the problem about his denture visited a general dental practitioner. As the dentist noticed the lesion like a hematoma on the left side of the tongue, he was introduced to our hospital. His medical history revealed that he had undergone the operation of stoma 20 years ago. He had full maxillary and mandibular dentures, but did not recall biting his tongue on his own. On physical examination, soft dark purple hematomas on the bilateral side of the tongue. We initially suspected a traumatic hematoma. However, multiple petechial hemorrhages were present on the oral mucosa, namely, subcutaneous hemorrhages on the palate and the bilateral buccal mucosa. Moreover, when the extremities were checked, some purpura were observed. Laboratory data showed the following: platelet 18,000 /μL. We consulted with the hematologist. A thorough examination revealed that the patient had ITP. Dentists should consider the possibility of encountering unaware ITP patients.

Abstract: This study aims to report an unusual clinical case of cemental tear in the upper left canine, presenting the clinical and radiographic characteristics of the lesion, predisposing factors, differential diagnosis, treatment and 12-month postoperative control. A 73-year-old male patient was referred for an apicectomy of the left maxillary lateral incisor. After the procedure the patient still had a capsulated intraosseous lesion at the apex communicating with the left maxillary canine. It was decided to place an immediate implant in that same region, which was later lost, and even so, the fistulated lesion continued to recur. After several attempts of curettage and total removal of the lesion the patient still presented it frequently. Through a Cone Beam Tomography, the diagnosis of cemental tear in the upper left canine was defined and its extraction was then performed. After the extraction, maintenance consultations were carried out in the subsequent periods of 3 months, 6 months and 12 months, where good bone healing was found and there was no more sign of infection. After 12 months of clinical follow-up, the surgical treatment proved to be quite efficient and, even without the placement of any type of biomaterial, bone neoformation could be observed in the region and there was no recurrence of the lesion.

Abstract: Objective: In order to solve the effective problem of removing the rotten material in the root canal, and can adapt to the various continuous surgical procedures in the root canal surgery. Methods: When it is necessary to clean the rotten tissue, place the device above the teeth after drilling, insert the inner tube into the hole and extend it to the required depth, and then further adjust the depth of the inner tube in the hole by adjusting the position of the outer tube of the driving mechanism. The driving mechanism is started so that the driving mechanism drives the elastic hollow part to rotate. Then, a liquid with a certain consistency is filled into the first cyst through a pipe so that the first cyst can be effectively propulsive and closely adhered to the corrupt tissue, while the inner tube is continuously pulled upward. The second capsule is continuously filled with liquid through the pipe, so that the second capsule can contact the tissue after cutting and fully contact the surface of the tissue after cutting and complete the sealing. In jecting the clean water into the hole on the teeth. The teeth can be filled through the cavity formed between the elastic hollow and the pipe by pouring the tooth filling material into the hole of the treated tooth. Results: The use of the device can adapt to a variety of continuous operation processes in root canal surgery, the use is more simple and convenient, and the operation is more efficient. Conclusion: The use of this device can adapt to a variety of continuous operation procedures in root canal surgery, which is simpler and more convenient to use, and more efficient to operate.

Abstract: Early orthodontic treatment based on occlusive guidance is an important aspect of dental care that focuses on improving the growth and development of the craniofacial region in children. This approach has been shown to be effective in reducing the occurrence and severity of malocclusion, which can have negative impacts on both physical and mental health. However, early orthodontic treatment based on occlusive guidance is not without its challenges. The process requires careful consideration of various factors, including the unpredictability of growth and development during childhood and adolescence. Furthermore, the transition from primary to permanent teeth presents unique challenges that require the integration and collaboration of multiple dental disciplines, including orthodontics, restorative dentistry, endodontics, and prevention. Despite the challenges, early orthodontic treatment based on occlusive guidance remains an essential aspect of dental care for children. To ensure that the best outcomes are achieved, it is important to select the right timing and treatment methods that are tailored to each child’s unique needs. This can be challenging due to the absence of a universal strategy for selecting treatment options. In light of this, this article provides guidance on the timing and selection of orthodontic treatment methods based on different stages of growth and development. By conducting a systematic review of the occlusive guidance management system, this article can assist clinicians in providing multidimensional prevention and early orthodontic treatment of malocclusion.

Abstract: Objective: To explore the application of self-made distractors to construct a unilateral DO model of rabbit mandible and evaluate the microstructure of bone specimens. Method: Designing a linear dual arm distractor and performing DO implantation surgery on 5 rabbits under local anesthesia. Stretching the mandible at rate of 1.0mm/day, 2 times/day for 10 days. After fixation for 3 months, taking mandibular specimens for gross observation, Micro-CT imaging and HE histological examination to analyze the bone density, maturity and three-dimensional structure of the new bone. Result: Except for one animal that died of unknown cause, the right mandibular body of the other animals was extended by about 10mm. The traction gap is completely filled with bright and red new bone with clear contours; Micro-CT reconstruction of three-dimensional bone images clearly shows high bone density in the gaps, with trabeculae arranging along the direction of distraction; HE staining shows that the bone trabeculae were connected into woven and layered bones, with a large number of concentric arranged bone plates surrounding the central canal to form the Haversian system, and osteoblasts proliferated actively. Conclusion: The use of Micro-CT and HE staining proves the success of the unilateral DO model of rabbit mandible using a self-made distractor, providing animal experiment for various biological factors and drug assisted methods to promote efficient DO in the later stage, and for its safe and effective clinical application.

Abstract: Human history is littered with epidemics. If these have devastated entire societies throughout the ages, and have left indelible scars in history, literature, the arts, and even in the human genome, they have nevertheless enabled him to adapt to circumstances and to create a kind of symbiosis with nature. The plague, the Spanish flu, cholera, Ebola or recently COVID-19, the return of an epidemic, even a pandemic, seems inevitable, but not ineluctable. Coronavirus disease (COVID-19) is a respiratory infectious disease caused by the SARS-COV-2 virus. This virus is not only spread by direct contact, but also by airborne droplets. This has led to an embarrassing situation for the government, which has to adopt a policy of last resort in terms of containment or isolation to limit the infection. The study is carried out in order to evaluate the online learning during the pandemic of COVID-19 among the students of the Faculty of Dentistry of Casablanca.
