Title: Prevalence of malocclusion in 15 yrs old school going children in Ahmedabad city
Biography:
Abstract:
Objective: The objective of this study was to determine the prevalence of malocclusion among school children of Ahmedabad city, Gujarat State, India after their mixed dentition period at the age of 15 years. Materials & Methods: The sample consisted of 930 children (486 males and 444 females) in the age 15 years randomly selected from twelve different schools in Ahmedabad city. The selections of the school were done by dividing the city into four zones. Further, 3 schools were selected from each zone and all the students who were willing to participate were included in the study. Occlusal anteroposterior relationships were assessed based on the Angle classification. Results: The results showed that about 74% of the subjects had malocclusion. Crowded incisors were found to be most common finding in subjects with class I malocclusion.

Title: Maxillary anterior teeth width proportion and its relation to facial measurements-a systematic review
Biography:
Mahdmood Dashti is last year dental student at Shahid Beheshti Univerisity of Medical Sciences in Tehran, Iran. He is Head of Iranin Dental Student’s Association Financial Committee. He has presented poster in some congress back in Iran.
Abstract:
Aim: This article reviews some of the most common dental proportion and the relation between maxillary anterior teeth width and some facial measurements to achieve pleasant esthetic appraisal. Methods & Materials: In this study we had reviewed articles from 2000 till now with these keywords: maxillary anterior teeth, dental proportion, golden proportion, recurrent esthetic dental (RED), esthetic, facial measurement, teeth width, smile. We used 9 out of 14 found articles based on the topic which was use of dental proportion and its relation to the facial measurement in the studies. Studies with restoration of anterior teeth such as crowns, veneers, fillings, etc. And facial cosmetic surgery such as rhinoplasty were excluded. Results: These studies illustrated that in different ethnic groups the relations are different, meaning teeth with different height are better have appropriate proportion due to their heights to achieve pleasant esthetic appraisal. Also correlation between width of maxillary anterior teeth and Interpupillary Distance (IPD) or Inner Canthal Distance (ICD) or Interalar Distance (IAD) have been reported. Conclusion: These studies showed that gender has nothing or a little to the correlation between maxillary anterior teeth width and facial measurements such as IPD, ICD, IAD. Also considered that dental proportion differs in teeth with different height.

Abstract:
In 1925, Angle described the Edgewise bracket in an article entitled "Latest and Best in Orthodontic Mechanism." The Edgewise appliance was designed as a means to provide positive control of mesiodistal and angular movements of teeth. The concept was simple, but the bracket provided so much control that it was difficult to make the anteroposterior inter-arch corrections necessary to treat Class II or Class III discrepancies. Since its invention, orthodontists have striven to overcome the inherent limitations of the Edgewise slot. In 1986, Kesling P and Rocke T modified the Edgewise archwire slot and stated that the Tip-Edge technique was for the Twenty First Century. In 2000 Kesling provocatively claimed that Angle had unintentionally placed an albatross around the necks of orthodontists-the Edgewise archwire slot. Kesling also stated that "90 percent of orthodontists do not have a clue about the most efficient and physiologic method of tooth movement - differential". In 2012, Chamda and Evans confirmed the ease of use of the appliance and found that the Tip-Edge technique was efficient and effective and achieved adequate anchorage control without the use of any adjuncts or extra-oral devices. This workshop will demonstrate the simplicity of the mechanics by which the Tip-Edge appliance operates and enables practitioners to correct difficult malocclusions non surgically.

Abstract:
Objective: The purpose of this study was to locate the fracture sites and treatment modalities of the different fractures. Material And Methods: Patients treated at the Oral and Maxillofacial Department of Kantipur dental college teaching hospital and research center during a one-year period between 2014 and 2015 were retrospectively evaluated with respect to age groups, gender, etiology, localization and type of fractures, treatment methods and complications. Results: 174 patients were included in the study, 142 (81.6%) males and 32 (18.4%) females, with a total of 244 mandibular fractures sites with a male/female ratio of 4.4:1. The most common causes of injury were falls (χ2=17.1607, P=0.0087) accounted for 139 (79.9%) of the fractures. The most common fracture sites, symphysis of the mandible being significantly (χ2=21, P=0.0008) affected than other sites. However, 96 (39.3%) and 132 (54.1%) of the fractures occurred on the right and left sides of the mandible respectively. Most patients had single (44.3%) and double (31.6%) fractures and this finding was significant (χ2=60.9314, P=0.0000). The fractures were successfully treated by arch bar and intermaxillary fixation, and open reduction and internal fixation. Conclusion: This study shows falls were the common cause of fracture and others being secondary. Symphysis was the common sites of fracture. Arch bar placement internal fixation and open reduction and internal fixation were the treatment modalities we used in our instution.

Abstract:
Canine impaction is a dental problem very often encountered in orthodontic practice. After the third molar, the canine is the most frequently impacted tooth. Bringing the impacted canine into a normal position is important for functional occlusion and the final esthetics of the orthodontic treatment. This article illustrates a peculiar case, in which all four permanent canines maintained their unerupted status at age of 16 years. All four impacted canines were surgically exposed, attachment bonded, traction given with K-9 spring and ideally positioned with fixed orthodontic mechanotherapy.

Title: Stem cells from exfoliated deciduous teeth, a way for pulp and dentin regeneration (an animal study)
Biography:
Shirin Shahnaseri is working as an Assistant Professor of Oral and Maxillofacial surgery in Isfahan University of Medical Sciences since 2010. She has been researching since 2005 and her special research field is harvesting of stem cells from adipose tissue for maxillofacial alveolar cleft reconstruction. She had done some project under process for TMD treatment by harvesting chondroblast from stem cells and pulp regeneration by stem cells harvested from deciduous teeth.
Abstract:
Dental pulp tissue has the potential to regenerate dentin in response to stimulations. Thus, stem cell therapy has considerable promise in the field of pulp dentin regeneration. The aim of this study is an in-vivo evaluation of pulp's stem cells capacity in pulp and dentin regeneration in dogs. In order to isolate stem cells, one Iranian mixed-breed and 5-months dog was used. The deciduous tooth was extracted. The pulp of tooth was isolated and exposed to type 1 collagenase enzyme. Isolated cells were cultured on Dulbecco’s modified Eagle’s medium (DMEM), supplemented with 10% fetal bovine serum (FBS) and 1% antibiotic. Polyglycolate (PGA) scaffolds were prepared and sanitized in 75% ethanol, and seeded with 4×104 cells. Twenty anterior and premolar dogs' teeth underwent shallow pulpotomy. Then all teeth were divided into three groups. 12 teeth were transplanted with seeded scaffolds and then cavities were filled with MTA and amalgam. Control groups consisted of four teeth with unseeded PGA restored with MTA and amalgam and four teeth with only MTA and amalgam. Eight weeks after transplantation, samples were histologically analyzed. Mann-Whitney U test was used to compare inflammation, calcific barrier and hyperemia and Chi-square test to compare necrosis and odontoblastic layer formation. There was no significant difference between 3 groups except for calcified barrier type between group 1 and 2, dentin like matrix, collagen fibers and small vessels observed in the cavity in group using stem cells. The results of the study suggest the possibility of pulp and dentin regeneration with stem cells in damaged teeth.

Abstract:
HIV infection is a major health concern in India. India has the third highest number of people living with HIV in the world with 2.1 million Indians accounting for about four out of 10 people infected with the deadly virus in the Asia Pacific region. There are considerable regional variations in the oral manifestations of HIV infection, depending both on the populations studied and on the clinical heterogeneity. The oral manifestations in Asian countries as compared to western countries and other developing nations in Africa and Latin Americas are relatively different. The constraint of resources in Asian countries hinders the possibility of providing an effective health care system. Though many studies have been conducted on oral manifestations in HIV, the research in Asia is currently at a pivotal juncture as the existing research is getting repetitive. Currently, Asian studies predominantly focus on prevalence of oral manifestations and assess their association with parameters of HIV infection, sociodemographic data and deleterious habits. Hence a cross sectional study was undertaken among HIV population in western India, Gujarat with main focus and objectives: 1) Evaluation and diagnostic usefulness of saliva for detection of HIV antibody 2) To calculate CD4 count of HIV positive patients. 2) To evaluate systemic manifestations of HIV positive patients. 3) To detect oro-maxillofacial manifestations in HIV positive patients. 4)To compare and correlate systemic and oro-maxillofacial manifestations of HIV positive patients with the CD4 count. Study population comprised of newly diagnosed 100 confirmed seropostive patients, before starting any antiretroviral therapy, were included. Saliva of HIV positive patients was collected and was tested by ELISA by using special reagents and modifications leading to detection of antibody in saliva. The oral lesions were diagnosed based on clinical manifestation using international criteria and CD4 count was determined within maximum 1 week of oral examination. Oral and systemic manifestations of HIV positive patients were recorded and correlated with CD4 counts. It was found that decrease in CD4 count is associated with a wide range of oral and systemic manifestations which can be used as prognostic marker for immune suppression in AIDS patient. This study can be very useful in epidemiological surveys, diagnosis and management of HIV positive patients.

Recently, he published an article in an internationaly reputed peer reviewed journal.
Abstract:
Purpose: There is not a universally accepted standard treatment protocol for the condylar fracture. The intent of this study is to explore the factors that are most responsible for the pleasing postoperative response. Patients and Methods: This study was a single-centre retrospective cohort study. The sample was composed of the cases of mandibular condylar fracture collected from the Craniomaxillofacial Trauma Unit of study hospital between January 2011 and September 2015. The Predictor variables were age, gender, occupation, cause of injury, injured side, combined injury, degree of displacement and damage shift, position of fracture, treatment timing, treatment method, and fracture reduction situation. The outcome variable was postoperative satisfaction (overall, physician and patient). Descriptive, univariate, and multivariate statistics were computed. P value was set at 0.05. Results: The sample was constituted of 102 cases. Male to female ratio was 2.1:1 with an average age of 29.02 ± 13.55 years. Manual workers were more; the primary cause was fall injury (50%). The most common combined fracture was mandibular symphysis fracture; condylar neck fractures in 64 sides (52%). The ratio of conservative versus surgical treatment was 1:2.73. The cause of injury, fracture displacement, treatment time and fracture reduction condition have the significant association with overall postoperative satisfactions (P<0.05).Whereas fracture displacement was excluded in patient satisfaction model(P>0.05) and occupation was affixed on it(P<0.05). Conclusion: The result of this study infers that the overall treatment effect is good or not good highly depends on the level of patients satisfaction. This level would be high with treatment timing as early as possible and the good quality of fracture reduction. Violent injury unfavorably affects the outcome, and the mental workers bear the result reasonably. However, it is not within the control of treatment methods and fracture displacement.

Abstract:
Implant dentistry has seen rapid and remarkable progress in recent years. Several questions have been raised concerning materials as well as designs of both implants and implant abutments to achieve maximum clinical success rates. An understanding of their properties will help the clinician in selecting the ideal prosthesis for each clinical case while promoting final esthetic outcomes. With the evolving technology and knowledge, an update of the current trends is necessary.The use of implants to replace missing teeth in the esthetic zone is challenging. The restorations are subjected to direct visual comparison with the adjacent natural teeth. Perfect three dimensional implant positioning and well-designed superstructures are therefore essential to mimic the appearance of a natural tooth and to achieve an optimal esthetic outcome.The development of computer aided design computer aided manufacturing (CAD/ CAM) technology has focused on precise and consistent manufacturing of zirconia ceramics with high strength and toughness. CAD/ CAM technology relies on exact dimensional predictions to compensate for sintering shrinkage, and is an economical and highly reproducible method for manufacturing complex and individual geometrics from a green or presintered ceramic material. Zirconia has become one of the dominant types of ceramic used for a variety of CAD/CAM restoration classes, including framework/ hand veneer, framework/pressed veneer , framework milled /veneer, full contour fixed prosthodontics , implant abutments, and large implant supported substructures. Although zirconia is currently the strongest dental ceramic material available, fabrication variations and finishing procedures can affect the longevity of this material as well as the veneer porcelain. Having a good working relationship with a dental laboratory is strongly recommended. Of the all-ceramic restorations produced in 2010, zirconia based units represented approximately 50% of that total. The introduction of computer aided design/ computer aided manufacturing (CAD/ CAM) has facilitated the use of superior dental ceramic, to enhance the fabrication of consistent and predictable restorations in terms of strength, marginal fit and esthetics. CAD/CAM technology in combination with zirconia ceramic has increasingly gained popularity in implant dentistry.Marginal accuracy, retention and color matching of esthetic implant supported crown are critical determinant in the over all success of implant therapy and yet it remains challenge. Especially with the innovative revolution of CAD/ CAM systems designs and materials which has improved and refined endlessly. So on understanding of their properties is a demand for helping the clinician in selecting the ideal prosthesis for each clinical case while promoting final esthetic outcomes. In this lecture we will spot light in a comparative way between different CAD/CAM techniques [Full contour CAD/CAM technique, Anatomical core CAD/CAM technique, over press CAD/CAM technique] ..we will show their marginal accuracy, color matching and retention when used as a cemented versus screw retained esthetic implant supported crowns.Digital implant dentistry isn’t the future …Far from it… digital implant dentistry is the “here and now” for dental implant practitioners.From digital treatment planning and delivery to patient communication, new technologies are changing the way dentists practice implant dentistry. The digital advancements in dentistry are growing at an incredible speed.

Abstract:
Background: We have recently reported a rapidly rising rates of adult obesity (Farshori et al, 2015) and rising cases of type II diabetes (T2DM) in adult Saudi population (Farshori et al, 2016). If diabetes is poorly controlled it can eventually lead to serious complications such as many types of cancers, heart disease, renal failure and the poor oral hygiene leading to gingivitis, severe periodontis and even tooth loss (Schulze and Busse, 2016). Methods: Thorough oral exams were performed by Vth year female dental students on a total of 114 female non diabetic subjects and 60 T2DM female patients to look for cases of dental carries, gingivitis, periodontitis, and tooth decay and tooth loss. The data was recorded and analyzed by 5th year female dental students. Results: In control group (age range 14-75 years, mean age 33.82 years), 89.47% showed signs of gingivitis and 31.57 % showed signs of serious periodontitis with 16.96 % tooth loss in control group. In comparison female diabetic patients (age range 23-71 years, mean age 45.1 years), 41.6% were Type I and 58.3% were T2DM patients. We found 95% of T2DM patients with gingivitis and 65% had severe periodontitis. Therefore our results show 89% of female control subjects showing signs of gingivitis as compared to 95% cases of gingivitis in diabetic patients. Although there was no significant difference in the cases of gingivitis between the control and diabetic female population however we found a statistically significant number of female T2DM patients showing signs of serious periodontitis (65%) as compared to the control population (31%). Similarly a significantly high percentage of tooth loss ((25.93%) was seen in diabetic patients as compared to the control group (16.96%). Conclusions: A high percentage of diabetic patients show serious cases of periodontitis (65%) and increased tooth loss (26% lost tooth) as compared to the control non diabetic patients with 32% showing periodontitis and 17% lost tooth.
