Corona virus disease 2019 caused by zoonotic virus SARS-CoV-2 (Severe respiratory syndrome corona virus 2) was first reported in Hubei, Wuhan, China in December 2019 when a group of 41 patients had a perplexing pneumonia. Since then, it has wrecked havoc in the entire world and was declared a pandemic by the WHO on 11th March 2020.
According to WHO, 2019-nCoV principally spreads through respiratory droplets, saliva, discharge from the nose and fomites, thus making dental care and other aerosol generating practices precarious in nature.
Saliva is a bio-mixture secreted from major and minor salivary glands and can play a vital role in prompt diagnosis and close contact transmission of the disease. Its viral load is mainly due to SARS-Cov-2 present in the lower and upper respiratory tract, gingival crevicular fluid via blood and the salivary glands itself where the virus attaches to the ACE2 receptors.
The nasopharyngeal and oropharyngeal swabs being used for testing cause discomfort to the patient and have a high chance of close contact transmission of the virus from the infected person to the health care individual. These swabs may cause bleeding in thrombocytopenic patients and the secretions to be tested may not be produced in 26% of the infected individuals. As compared to this, salivary tests are non invasive, easy to perform, have a lesser chance of cross transmission and are more sensitive to the virus.
This poster discusses the benefits and scope of using saliva as a diagnostic aid during COVID-19.

Title: Multidisciplinary treatment approach in the rehabilitation of missing permanent maxillary central incisors: case report
Time : 11:30-12:00
Maja Hočevar completed her studies of dental medicine at The Faculty of Medicine, University Ljubljana. During her undergraduate studies she collaborate at the Orthodontics Department under the direction of Prof. Dr. Ovsenik. Desire for knowledge led her to many dental clinics abroad. She participate in research study at Virginia Commonwealth University, USA. Until now she presented many papers at reputed congresses around the world. She continued furthering education while working as general dentist, especially in the field of aesthetic dentistry and orthodontics.
Traumatic dental injuries often occur as a result of an accident or sport injury and range from minor chipping to total tooth loss. Avulsion of permanent teeth is the most serious form of dental trauma and represent up to 1% of all dental injuries. Patients with missing anterior teeth may suffer extreme psychological trauma because of unfavorable appearance, phonetic handicap and reduced masticatory ability. Treatment of missing anterior teeth usually represent multidisciplinary clinical challenge and number of clinical factors should be considered. The main factors that influence the choice of therapy are edentulous ridge characteristics, gingival biotype, space conditions of the dental arch, occlusal scheme and patient expectations. Restorative treatment options depend on either to open or close the missing incisor space. In the case of orthodontic space closure, the adjacent teeth should be reshaped to mimic the missing incisor. The other option is to maintain the space for subsequent placement of an implant or some other form of prosthetic treatment. This clinical report describes a 19-year-old male with history of dental trauma who lost both permanent maxillary central incisors. Clinical examination and radiographic findings revealed insufficient bucco-palatal bone ridge which did not allow implant placement in the site of the missing maxillary central incisor. Orthodontic space closure of missing maxillary central incisor with lateral incisors was made and space opening in the site of lateral incisor was maintained for later implant placement. Final prosthodontic treatment included all-ceramic crowns in a position of all four maxillary incisors.

SENOUCI BEREKSI Fatima Zohra, 26 years old, from Tlemcen (ALGERIA), resident in 3rd year of conservative dentistry and endodontics at the University Hospital of Tlemcen.I do a lot of scientific research concerning endodontics, I also participated in a lot of congresses including the 8th international symposium of dentistry in Monastir, Tunisia in 2018; and the French society of pediatric dentistry in Marseille, France in 2017.
MTA® is currently considered to be the gold standard of endodontic repair cements, which has been clinically and radiologically satisfactory and has greatly attributed to postoperative bone and mucosal healing. The objective of this work is to review the clinical and radiological effectiveness of MTA® in relation to its application in different clinical protocols In the conservative dentistry and endodontic department of Tlemcen (Algeria), five patients with different pathologies were treated. MTA® has been used in five operative protocols: apexification, treatment of external root resorptions, repairing of root perforations, apical root fractures and retrograde root canal fillings.
Our therapeutic strategy was first to achieve a watertight seal by placing an MTA® apical barrier, which will secondly induce the mineralization processes. Our clinical trials show high success rates achieved with MTA®, especially in apical surgery, apart from some difficulty in handling and stability of the MTA® felt by the operator. The MTA® is therefore considered a potentially alternative material to other materials used in our endodontic service.

Rajesh Dashaputra completed his Bachelor of Dentistry (B.D.S.) from University of Mumbai in 1985. He has trained in implantology very early when implants were introduced in India and joined as member of ICOI (International Congress of Oral Implantologists) since 1995. He has been working in prestigious research institution of BARC under the dept. of Atomic Energy, govt. of INDIA for more than 23 years as a busy consultant dental implant surgeon with full use of digital technologies including CT and CAD CAM. He now has mastered and conducted more than 16 implant systems and mentors for few of the leaders. He also completed PGDM in Clinical Research with specialisation in CDM (clinical data management). He has further pioneered in another area of interest - healthcare informatics. He is fully trains students in implantology, computer guided solutions in dental treatments, healthcare software systems and telemedicine. He regularly speaks at international events and also has many publications including prestigious IJME (Indian journal of medical Ethics)? Canadian dialogue (due) and JDHODT and involved in stem cell and biomaterials research.
Many times differences in opinion during selection of treatment modalities and options given to patients in routine general practice marks the difference in level of care. With the advent of new technologies in modern 3D dentistry training and delivering new modalities is a challenge and race against time. Implant dentistry as well as restorative dentistry is changing rapidly with many even drastically different approaches preached by mentors for similar situations keeps the generalists confused.
The 3Ai route- a simplification protocol devised explains mainly the core concepts among different modalities to be understood and how to prepare cases for a flexibility to choose next better future options and degree of difficulty in consideration.
The talk reviews different techniques and with case presentations to support a new view.

Purpose: Due to the complex morphological variations of teeth, a successful root canal treatment (RCT) is always a compelling issue for dentists. Cone beam computed tomography (CBCT) is one of the emerging imaging modality for RCTs. Although it provides a 3D view, the patient dose is a substantial limiting factor. The aim of the study is to reduce the patient dose of the CBCT imaging specific to the RCTs by optimization techniques in different acquisition protocols.
Method: An extracted 3rd molar that was embedded in a c-type silicon representing soft tissue was used for the optimization procedure. Promax 3D Max CBCT device was utilized to produce 3D images. KVp, mA and exposure time were considered as the acquisition parameters. Image resolution was 421x421x511. Voxel size was 0.1 mm3. Image quality was quantified by the Dice Similarity Index. The dose was recorded µGy by the software of the CBCT.
Results: Overall 18 different protocols (3 for KVp, 2 for mA and 2 for exposure time) were evaluated. Radiation dose was reduced from 326 µGy to 33 µGy while maintaining a Dice Similarity Index of 0.5 and above.
Conclusion: The proposed optimization technique might provide an evident dose reduction of CBCT imaging with an acceptable imaging quality for RCT.
