Keynote: Current state of digital dentistry: Digital dentures and their properties
Biography:
Rata Rokhshad is a 6th year dental student at Tehran medical sciences, Islamic Azad University, Tehran, Iran. She has been working in a digital dental office and a digital dental lab. She has published papers in dental journals. she has presented several poster presentation and oral lectures in different dental congress.
Abstract:
Digital technologies offer the opportunity to integrate facial scans into the design of digital dentures and provide a 3D preview and simulation of the tooth arrangement for treatment planning. The conventional fabrication methods are, error-prone, time-consuming, complex, and expensive procedures. Removable partial dentures(RPD) and Complete dentures(CD) fabricated by computer-aided design and computer-aided manufacturing (CAD-CAM) techniques have become popular. Therefore, we reviewed the treatment outcomes of concepts used for implant-supported overdentures, RPDs and CDs.
Method and Materials:
An effective search of the literature was done, mainly through pubmed and Google Scholar with( "CAD-CAM" and "dentures" or "Digital" or "RPD") as keywords. We found 42 published studies from 2003 to 2020. According to the research methods 21 articles were chosen.
Results:
Digital dentures can be fabricated digital or combined analog-digital while using intraoral scanners or extraoral scanners. Milling and rapid prototyping (3D printing), have been widely used in the fabrication of dentures. They have been reported to have clinically acceptable results. Digital dentures were evaluated by their accuracy, patients satisfaction, outcomes and their procedures. CAD/CAM dentures have several advantages such as reducing clinical chair time and the number of visits, digital archiving, significantly higher retention, and more favorable clinical and patient-centered, less denture tooth movement, increased toughness, ideal flexural strength, and higher elastic modulus. CAD/CAM dentures showed at least comparable accuracy. However, disadvantages such as high cost, software errors, and lack of jaw relations in functional state, are still the problem.
Conclusions:
CAD/CAM dentures had better clinical outcomes than conventional dentures. Although, there are some limitations in the manufacturing procedures. Results of studies suggest there is a great potential for further investigations.

Session Introduction
Peter P. Flores
DMD, MS Dental Education Department of Dentistry, Centro Escolar University, Philippines
Title: Module development in the teachings of Removable partial Denture (RPD
Biography:
Dr. Peter P. Flores has completed his Masters of Science Health Science Education Major in Dental Education from Centro Escolar University, Manila Philippines. He is a faculty member at Centro Escolar university, Makati Department of Dentistry. His expertise and interest is on Cosmetic Dentistry and Prosthodontics. He is also a member and a graduate of the Philippine Association of Esthetic Dentistry.
Abstract:
Removable Partial Denture (RPD) is defined as the division in prosthodontics that pertains to the restoration and maintenance of the oral function and appearance of the patient. This study was aimed to develop a simplified module in RPD framework designing that can easily understand and followed by students and clinicians. The research design used is descriptive qualitative research method. There were 8 student respondents and 5 faculty respondents selected to answer open ended questions conducted on a face-to-face interview, to assess the respondent's behavior, beliefs and attitudes towards RPD. The student clinicians’ level of competencies in understanding and comprehending the RPD concepts affected their case analysis process which also affected their choice of appropriate components for the RPD prosthesis. The gaps identified in this research were incomplete comprehension in conducting case analysis, distinguishing the correct designing principles, and identification of the correct RPD components in the designing process. The poor decision performance of the clinicians and students in removable partial denture cases are concluded from the wrong and inappropriate designing of the RPD framework. An instructional module in framework designing that includes a step by step sequence approach to come up with an appropriate RPD framework designing has been developed which is necessary to address the issues faced by the students and clinicians.

Title: Evaluation of Oral Health Status in Multiple Sclerosis Patients
Biography:
Marziye Rezaei is a 6th year dental student in Tehran University Of Medical Sciences.She is in charge of Dental College Mentorship in Tehran University Of Medical Sciences about educational ,mental or research matters.Besides,she had some oral presentations like Usern Miniature Talk 2020,Student conference in Northdent Congress and Poster presentation about educational ideas for dental students in Tehran.
Abstract:
Background: Recent trends in the increasing incidence rate of MS have led to need attention to oral health status. Oral health plays an important role in overall peoples' health. The purpose of this paper is assessment of oral and dental hygiene indexes in MS patients and compare it with a healthy control group.
Material & Methods: Forty patients that fulfilled the MS McDonald criteria were enrolled in our study and forty healthy volunteers were recruited into the control group. Dental and periodontal examination were carried out in order to evaluate of the decayed, missing and filled teeth (DMFT) index, the assessment of community periodontal index of treatment needs (CPITN) index and determination of tooth wear status and oral health status. Statistical analysis was done using SPSS statistical package (version 22, IBM).
Results: Mean age, educational level and tooth brushing was not statistically different between MS patients and control group. DMFT index in MS patients was significantly higher than control group (p=0.011). There was statistically significant difference in CPITN index between cases and control group (p=0.042). There was no statistically significant difference between case and control group in tooth wear index of maxillary teeth (p=0.28) and mandibular teeth (p=0.475).
Conclusion: This finding, suggests that MS patients need more attention to dental and oral health. Considering increase in prevalence of multiple sclerosis in Iran in recent years, planning a protocol for oral hygiene instruction is necessary. In this regard, coordination between neurologists and oral medicine specialists may improve comprehensive care.

Title: Unicystic Ameloblastoma mimicking Periodontal lateral cyst: a rare case report.
Biography:
Maya fedhile is completing her last year at the Dental University of Monastir and plans to present her thesis for the Doctor in Dentistry diploma on novembre 2021 at the age of 24 years. She is the president of the Tunisian Red Cresent Dental Comitee. She has one article submited and another one under writting process.
Abstract:
Intraosseous unicystic ameloblastoma (UA) is rare subtype of a true neoplasm of odontogenic epithelial origin: ameloblastoma. Despite its rareness, dealing with UA is problematic. It is usually mistaken for an odontogenic cyst, and biopsy is rarely relevant because of its multiple grow patterns. The biggest challenge remains the treatment choice. When we are facing a mural UA presenting strong similarities with the periodontal lateral cyst and having high rates of recurrence, how the balance between a young age, psychological fragility, post operation process and biopsy diagnostic need is found? That was our dilemma. Our patient is a 23 years old men with a mural unicystic ameloblastoma, diagnosed with general anxiety disorder. The final decision was to turn to a simple enucleation because of the small size of the lesion and its radiological features strongly evoked a periodontal lateral cyst. Besides, his young age, psychological condition and its proximity to the surrounding soft tissues guided us toward the simple enucleation. Two years later, no sign of radiological recurrence was noted. However, we are aware of a later resection eventuality in case of recurrence
