Abstract:

Tradition holds that the people we serve are patients. Yet, consumer-centric practices think about things differently than pure patient model practices do. Dental practices are consolidating into clinics and are being taken over by practice management companies. The success of dental practice or an oral care company can be profoundly influenced by online consumer reviews by patients on online sites, such as health grades and Yelp. It is time to rethink the terms of engagement we have with the people we serve, the people we have been accustomed to regard as patients? This session describes the once in a life time marketplace shift and what is means for dental practices and oral care companies and delivers solutions that will
help attract and retain clients. Rowpar Pharmaceuticals makes and markets the ClōSYS brand of oral care products to dentists
and to consumers. ClōSYS is now the #1 preferred oral care products on Amazon.com, has a Facebook page with over 30,000
followers, and is in the top 10% of oral care products in US pharmacies nationally. Rowpar received the Corporate Live Wire
Award for Innovation in oral care in North America in 2017 and 2018 and received the Fast Lane Company Award from
the Arizona Bioscience Association in 2018. Rowpar has worked with dental and medical professionals and their practices
and clinics, riding the tide of change to where consumer-centric business succeeds. From the CloSYS story, and the story of
the practices, clinics and businesses with which Rowpar was partnered, the session will present keys to building a successful
consumer-centric practice.

Emil Svoboda

Park Place Dental Centre, Canada

Keynote: Prevention of peri-implant disease by design and protocol

Time : 10:25-11:05

Conference Series American Dentistry 2018 International Conference Keynote Speaker Emil Svoboda photo
Biography:

Emil Svoboda has earned his BSc (1974), PhD (1978) and DDS (1982) at the University of Toronto. His undergraduate work involved general sciences including Bacteriology and Virology. His PhD research was supervised by Drs AH Melcher and DM Brunette and was part of the MRC group in Periodontal Physiology in the Faculty of Dentistry.

Abstract:

The incidence of prosthetic related peri-implant disease is on the rise. Abutment manufacturers must comply with Government and ISO Standards in order to sell their products in North America. These standards assume that the dentist will install these abutments according to manufacturer’s specifications and thus optimize the implant-abutment connection. The current screw-in prosthesis installation systems make it unlikely that dentists can consistently comply with these regulations. The basis of the problem rests in the fact that all dental models are inaccurate, and thus the prosthesis made to fit a dental model is also inaccurate. The screw-in installation technique dictates that the abutments are to be attached to the prosthesis on the dental model, before being installed into the mouth. The abutments are thus constrained by the inaccurate prosthesis, and their fit onto their respective dental implants cannot be optimized. It exposes our patients to the known “technique related” risk factor for peri-implant disease, known as the implant-abutment misfit or macrogap. Applying an intra-oral cementation
step to the screw-in technique, can solve this macrogap and misfit problem. The technique involves the use of well-designed
custom abutments, prostheses and supporting techniques that are sensitive to the Gingival Effects™ and precludes cement
voids, overhangs and open margins.

Biography:

Amir Hadjhamou has obtained his post-doctoral degrees in Prosthodontics and Implantology from University Lyon I where he was also appointed as lecturer at the faculty of dentistry, In addition to his clinical duties in the Oral Maxillofacial department and Prosthodontics department, at Hotel-Dieu Hospital, Lyon, France. He is currently an Adjunct Assistant Professor at the University Lyon in France.

Abstract:

Beauty lies in the eye of the beholder. Patients seeking elective aesthetic treatments have become more demanding in terms
of the results desired and/or expected. Modern techniques and approaches have been introduced and a new work flow and protocol is recommended. One of the most common aesthetic treatments is porcelain laminate veneers. Thanks to the latest developments in the materials, bonding techniques and types of ceramics available nowadays, it is now possible to offer our patients a predictable aesthetic result with minimal compromise to the dental tissues. In order to achieve that, a precise workflow and a specific set of steps should be followed in such an approach with minimally invasive notions, starting with Dental photography, Initial impressions, Digital Smile Design, wax up, Fabrication of a Silicone Key, Mock ups, and deep cuts through the mock up. Proper temporization and impression techniques and materials as well as respecting the recommended cementation protocols are mandatory for the long-term success of these restorations. This presentation will focus on the workflow, clinical steps and protocol followed in the fabrication of porcelain laminate veneers from A to Z.

Session Introduction

Konstantinos Bakos

UAB School of Dentistry, USA

Title: Temponary anchorage devices in orthodontics
Biography:

Konstantinos Bakos has completed his dental training at Aristotle University of Thessaloniki in Greece and his advanced educational training in Orthodontics at
University of Alabama, USA. He is currently a PhD candidate and scientific Assistant at the Department of Orthodontics at Aristotle University of Thessaloniki. He is an eligible member of the American Board of Orthodontics and a WFO, EOS, GRESLO and EOGME fellow.

Abstract:

Orthodontic anchorage is an important factor in obtaining good treatment results. Stable anchorage is a pre-requisite for orthodontic treatment with fixed appliances. Until lately, several conventional orthodontic modalities, such as transpalatal arches, headgears, Nance buttons, or the application of differential forces, were used for this purpose. However, it is difficult to obtain stable anchorage with such appliances even with the full cooperation of the patient. Their clinical effectiveness lies in their ability to maintain close contact with the bone thus remaining stable during orthodontic treatment while resisting
reactive forces thus mini- mizing anchorage loss. Systematic reviews show success rates ranging from 80% to 100% for the Tads. Mini-implants were introduced at the start of the 21st century as a new means of precisely controlling tooth movements during some orthodontic treatments. MIs are fabricated from stainless steel, commercially pure titanium, or titanium alloy
with a diameter of 1 to 2 mm and length of 8 to 20 mm, and they are not osseointegrated. Mini-implants are frequently placed between the roots of teeth, but may also be sited in the roof of the mouth. They are then connected to a fixed brace to help move the teeth. Survival of non-osseointegrated implants seems to be affected by many risks. The use of MIs significantly decreased or negated loss of anchorage. MIs were found more effective in supporting anchorage when they were used in the mandible, between the second premolar and the first molar, when two MIs were inserted into a patient’s jaw, when they were directly connected, when they were used in adult patients, as well as when treatment lasted more than 12 mos. MIs used for anchorage have a success rate of 87.7%, with no significant differences between the various subgroups.

Abstract:

Ameloblastic fibroma is a rare, slow-growing benign neoplasm, which comprises tissue of odontogenic origin. It constitutes 2% of odontogenic tumors and can occur at any age but tends to have a predilection to present in the first two decades of life. The posterior mandible is the most commonly affected site. Herein, we describe the case of a 6-year-old Caucasian
male who presented to the Oral and Maxillofacial Department at Alder Hey Children's’ Hospital, Liverpool, United Kingdom with a painless expansive mass in the left mandible which was diagnosed as a benign ameloblastic fibroma. The lesion was surgically enucleated and reconstructed with a parietal calvarial bone graft. A literature search using the PubMed, Embase
and CINAHL databases was performed. The terms included in the search were Ameloblastic, Fibroma, Ameloblastic Fibroma and Odontogenic Tumor. We further meshed all search terms to incorporate a wide range of alternative phrases surrounding the topic. Our results produced 604 papers, from which duplicates were removed and this left 334 papers to review. Of these
papers, the highest level of evidence was an abstract on a systematic review by Chrcanovic et al 2017. The management of AF is challenging, and there is no clear consensus regarding a conservative versus a more aggressive approach. In our opinion, a ‘case specific’ approach is appropriate. The aims of treatment are to remove the tumor and decrease the chances of recurrence while preserving adjacent vital structures when safe to do so.

Omar El Bayoumy he is an orthodontist and founder and owner of Omar Dental Center.

Abstract:

Mini-implants have influenced orthodontic treatment plans by providing possible management of complicated discrepancies than those treatable by conventional biomechanics. By the help of mini-implants, force can be applied directly to the, bone-borne anchor unit. Therefore, mini-implants not only eliminated concerns about anchorage demanding cases, but they also have enabled clinicians to overcome tooth movement in three dimensions. Furthermore, adjunctive orthodontic treatments in adults, and treatment for impacted teeth are the other indication of mini-implant treatment. Mini -implants were grouped as follow: common appliances for providing orthodontic anchorage, bio-mechanical details of mini-implants and their insertion, clinical application of mini-implants for orthognathic treatments, limitations and possible complications. In conclusion, mini-implant evolved the orthodontic treatment plans and compromised the required orthognathic surgery. Malocclusion treatment and pure orthodontic orthopedic movements in the three-dimensions have become recently possible by using mini-implant to provide skeletal anchorage.

Abstract:

In recent years a portion of the scientific literature and clinical trials from all over the world have shown an anatomicalfunctional and pathophysiological connection between craniomandibular and craniocervical dysfunction, connecting various zones of the organism in a single tonic-postural system. This research is based on biomechanical concept theory, Molar Lever conception and Domino effect reaction in organism. According to this theory, when dental support is not adequate the skull tends to collapse. Thus the top cervical vertebrae get miss-aligned and the skull tilts and moves away from a symmetrical and balanced position on top of the shoulders. When postural collapse affects, strains, compresses and twists the brain stem, the body reacts with neurological symptoms. They are automatic unconscious reflexes that do not make it past the brain stem to the conscious brain so called dystonia involuntary asymmetric muscle contractions. This study shows new vision in the treatment of cervical dystonia, as a bio-mechanical approach. Research is based on clinical cases using starecta method, modified dental splint –The rectificier to solve a postural problem. Each case is individual and needs several diagnostic methods (postural platform, stabilometric Platforms, x-rays, MRI scan and Face photos) according to the diagnoses. Statistics is based on multi analysis and effectiveness of this conception. You can solve a postural problem only if you know precisely how the bio-mechanism works and therefore the exact relationship between teeth, occlusion and posture.

Abstract:

Introduction: In Greek, “ergo” means work and “nomos” means natural systems or laws. The term ergonomics was rustled up by British psycholo¬gist Hywelmurrel, at the 1949 convention at the United Kingdom, which later steered the foundation of the ergonomic society. Ergonomics can be defined as, the scientific disci¬plines concerned with the indulgent of interactions
among human being and supplementary elements of a system, and the occupation that applies principles, data, meth¬ods and theory to scheme in order to augment human well-being and by large system performance. The good news is that these predicaments can be sidestepped by collective awareness of the postures used for the duration of the work, reforming the
workstation to encourage examining the impact of instrument use on upper extremity pain, neutral positions, and tailing hale and hearty work practices to lessen the stress of dental work on the practitioner’s body. This article introduces the signs, symptoms, and risk factors of musculoskeletal disorders. The article also converses the imperative issue of posture and offers
ten recommendations to recuperate your posture to allow you to work with efficiency coupled with comfort.
 
Materials & Methods: The presentation of this systematic review is in accordance with the PRISMA statement. Meta-analysis is done by using Covidence tool. The review included articles published in the last 10 years, from 2007 to 2017 on the MEDLINE, Scopus, and Cochrane Library. The search strategy used a combination of free text terms controlled vocabulary based on the following
 
keywords: ergonomic, dentist, musculoskeletal, posture, and prevention, neck pain, used with these search strings: dentist + prevention + ergonomic, dentistry + musculoskeletal + prevention, dentist + prevention + neck pain, additionally, we practiced a hand search on reference lists of the selected articles and reviews for a wider analysis. Relevant reports were selected
according to inclusion and exclusion criteria. Finally, the compatible full texts were independently assessed for definitive eligibility.
 
Results: Online research indicated 2098 references: PubMed (1719), Scopus (357) and the Cochrane Library (22). Of these, 604
were excluded because they were unrelated to dentistry and the occupational hazards of dental practitioners. Of the remaining
866 items were excluded due to duplication. The full text of 628 studies was assessed, 614 papers that did not meet inclusion
criteria were excluded. Ultimately, 14 studies were included in this review
Conclusion: Ergonomic characterization of dental work methods has revealed various occupational risk factors inherent in dental procedures and their contribution to a high degree of MSD observed among dentists. Well planned ergonomic intervention program can reduce the overall burden of this problem. By making small changes in work practices, instrument usage, posture, workstation setup, and health practices, you can greatly affect your ability to provide quality care over a long, healthy, and successful career in dentistry.

Abstract:

The impact of malocclusion on quality of life has been the objective of study in different populations. A total of 210 students (105 foreign students and 105 local students) studying in Nanjing University and Southeast University of Nanjing were selected for the study. Data were collected with the questionnaire, which included the desire for orthodontic treatment,
satisfaction with their dental appearance, importance of well-aligned teeth, awareness of other teeth and self-perception of psychosocial impact of malocclusion and clinical examination was done by a trained and calibrated orthodontist to assess the ICON index. The independent variables which were statistically significant were screened using logistic regression analysis
with the method of forward stepwise and regarded as factors affecting the subjective need for orthodontic treatment. The p value was taken as p<0.05. The results of my research were very interesting which I would like to share with the participants in the conference. Besides this, I would also like to share my experience working as a foreign expert consultant orthodontist in China and I hope my presentation will be knowledgeable as well as interesting to all the participants of the conference.

Abstract:

This research aimed to investigate the association of inferior alveolar nerve block injection (IANB) and procedural pain with contributing psychological factors in patients undergoing endodontic therapy. Of 208 patients who had tooth with symptomatic irreversible pulpitis and required an IANB injection, 164 patients completed the study. Participants fill out questionnaires on procedural pain (needle insertion pain, anesthesia solution deposition pain and access cavity preparation pain) and psychological factors (depression, anxiety and personality traits). For measuring pain Wong Baker Faces Pain Rating
Scale (WBS) and Visual Analog Scale (VAS) were used. Participants mean age was 34.63 years. Significantly depressed patients felt higher levels of pain for needle insertion as well as anesthesia solution deposition in both Scales (WBS: T1; (OR=1.08; 95% CI=1.01, 1.22) ,T2; (OR=1.09; 95% CI=1.02, 1.25), and VAS: T1; (OR=1.12; 95% CI=1.03, 1.29) ,T2;(OR=1.13; 95% CI=1.05,1.32)), but not in access cavity preparation. Among personality traits, the factor mostly associated with feeling higher levels of pain was neuroticism in both scales (WBS: T1;(OR=1.10; 95% CI=1.03, 1.25) ,T2; (OR=1.08; 95% CI=1.02,1.28), and VAS: T1;(OR=1.11; 95% CI=1.02, 1.28) ,T2; (OR=1.09; 95% CI=1.01, 1.20) ). It seems that depression and neuroticism can be considered as risk factors for feeling higher levels of pain during dental treatment. For helping these patients effort by both dentist and psychologist may be needed.

Abstract:

Objectives: Psychosomatic problems such as health anxiety are a newly discussed topic in today’s dentistry. The aim of this
study was to clarify the role of these factors in pain perception during RCT procedures.
 
Method: Data for this clinical study was gathered from 208 patients (mean age of 34.63) were referred to the endodontic department of the Isfahan University of Medical Science and had at least one mandibular molar tooth with symptomatic irreversible pulpitis. Participants were not able to fill out all the questions were excluded. For measuring pain, Wong-Baker
Faces Pain Rating Scale (WBS) and Visual Analog Scale (VAS) were used.
 
Result: Although significant levels of pain was not reported by high stressed patients in access cavity preparation, interestingly
they felt more pain during needle insertion as well as anesthesia solution deposition in both scales (WBS: T1;(OR=2.50;
95% CI=1.22,5.05) ,T2; (OR=2.13; 95% CI=1.05,4.31), and VAS: T1; (OR=2.25; 95% CI=1.11,4.59) ,T2; (OR=2.21; 95%
CI=1.09,4.48)). Among psychosomatic factors, the factor mostly associated with feeling more pain was health anxiety in both
scales (WBS: T1; (OR=2.40; 95% CI=1.19, 5.35), T2; (OR=2.24; 95% CI=1.08, 4.60), and VAS: T1; (OR=2.23; 95% CI=1.07,
4.65), T2; (OR=2.15; 95% CI=1.04, 4.44)).
 
Conclusion: It seems high stress and health anxiety can be considered as risk factors for more pain sensation during dental
treatment while researching in this field is a road less traveled. So, more effort is needed for controlling psychosomatic factors
by dental professionals.

Title: Oral health conditions of children ages 6-12 in Barangay 81: An assessment
Biography:

Raminkhoo Roshanak is a dentist graduated from Shahid Beheshti University of Medical Sciences and Health Services, Iran. In partial fulfillment of the requirements for the degree of Doctor of Dental medicine, This thesis entitled: Oral health conditions of children ages 6-12 in Barangay 81.

Abstract:

This study primarily aimed to assess the oral health condition of children ages 6-12-year-old in Barangay 81. It also aimed to find out how living in a poor Barangay affected quality of life, dental hygiene and oral health care of the children living in the area? The researcher used descriptive method. It examined if there was a significant association between the socioeconomic
status, educational attainment of parents, age, gender of children ages 6-12-year-old and oral health condition of the respondents. This study used a random sampling of 40 children ages 6-12-year old of Barangay 81 for interview and data gathering. A total of 40 children aged 6-12-year old were included. The prevalence of Dental caries was 97.5%. 30% had malocclusion; 15% had thumb sucking, 20% had premature loss of tooth, 27.5% had gum disease; 2.5% had lip sucking; 2.5% had mouth ulcer; 5% had Bruxism; 0% had acid erosion and 27.5% had broken teeth. The results indicated that dental caries was highly prevalent in the Barangay 81 accounting to 97.5% of respondents. Number of the dental problems in male was more than female. In the poor location, majority of the parents had a low degree of education. Also in the hypothesis, there was no association between socio-economic status, age, gender, educational attainment and oral health conditions of the respondents as confirmed by Chi square to be of no significance association because x2< tubular value. This may be due to a widespread neglect of oral health due to failure of parents to maintain oral hygiene of their child. Despite new oral product and outreach programs, this high level of untreated caries in this age bracket 6-12 years old raises concern.

Title: Treatment of severe idiopathic gingival fibromatosis in mixed dentition
Biography:

Virgílio Roriz has completed his PhD from University of São Paulo, School of Dentistry, Riberirão Preto, SP. He is the Professor in Federal University of Goiás
School of Dentistry, Department of Periodontics. He has published more than 16 papers in national and international journals.

Abstract:

Gingival fibromatosis may occur as an isolated finding or in combination with additional clinical problems associated with some syndromes. It may result in difficulties with proper dental hygiene keeping, chewing and occlusion. This work aims to describe a case of a child that was submitted a periodontal surgery for tissue removal caused by severe idiopathic gingival fibromatosis (IGF). The case study begins with a 10 years old male patient reported that presented a very large gingiva and he related about difficulty of tooth brushing. As treatment for resolution of the case, it was opted for the gingivectomy
surgery. This procedure was performed using the internal bevel technique with blade 15c at 45º with the alveolar bone crest, surrounding all the vestibular teeth’s faces and the palatine faces of the molars, removing about 4mm of gingival tissue. During urgery, teeth 64, 65 and 84 were extracted due they presented great mobility. A small part of this material was sent for histopathological analysis. Histological sections revealed the presence of an epithelial lining showing marked acanthosis and additionally, connective tissue hyperplasia was observed, such findings compatible with fibroepithelial hyperplasia. Based on medical history, clinical examination and histopathological study of gingival tissue biopsies the patient was diagnosed with IGF. After six months of follow-up, the patient was very satisfied with the aesthetic and functional results because the crowns were much more exposed in the oral cavity, facilitating mastication and hygiene.

Abstract:

Background: GTR technique is the gold standard for periodontal intrabony regenerative therapy. The aim of this study was
to evaluate the effect of using L-PRF and EMD growth factors along with GTR technique for regeneration of periodontal
intrabony defects.
 
Methods & Materials: Forty-five intrabony defects resulted from periodontal disease which can be reconstructed were enrolled in the study. Group 1 just got GTR treatment as control group, group 2 got L-PRF along with GTR treatment and in group three EMD used along with GTR. Clinical factors such as periodontal probing depth (PPD), clinical attachment level (CAL), keratinized gingival width (KGW) and bleeding on probing (BOP) were evaluated before and six months after treatment. Also amount of bone fill was evaluated with standard radiography.
 
Result: Treatment in all three groups significantly result in reduction of PPD and gaining of CAL. Sites with BOP significantly decreased, defects significantly filled with bone, however, there was no significant difference in KGW. Intragroup comparison showed no significant difference among groups in evaluated factors. But the most PPD reduction was 5.4±1 in L-PRF+GTR
group, the most CAL gain was 3.37±2 in GTR group, the most reduction in BOP sites were 14 sites in L-PRF+GTR groups and the most bone fill was 73% in GTR group.
 
Conclusion: Using EMD or L-PRF along GTR treatment does not have additional effect on positive results of GTR treatment alone.

Biography:

Objective: The objective of this study was to evaluate the degree of enamel demineralization of teeth bonded with ceramic and metal brackets.
 
Materials & Methods: In this cross-sectional experimental in-vitro study, 60 extracted human premolar teeth were selected according to certain criteria. They were divided into three groups; 20 premolar teeth in each group. Teeth in group-1 were bonded with APC Plus Adhesive Ceramic brackets, and teeth in group-2 were bonded with APC Plus Adhesive Metal brackets, while teeth in group-3 were not bonded with any brackets “control group”. All groups were then immersed in demineralization media, de-bonded, sectioned into three parts (proximal-1, middle, and proximal-2), and evaluated in the aspect of enamel
demineralization under Scanning Electron Microscope.
 
Results: On tooth level, the results show that the control group has significantly less enamel demineralization compared to the two experimental groups with mean value of 145.3μm and 192.7μm, respectively (P=0.000). The mean value of enamel demineralization in metal group is 55.93μm compared to 72.55μm in ceramic group, which is significantly less (P≤0.05), while there is no difference between the control and metal group with regard to enamel demineralization. On section level, the control group has significantly less enamel demineralization in all three sections compared to the ceramic group, while the significance is found in one of proximal section when compared with the metal group. Moreover, the ceramic group has significantly higher enamel demineralization in the middle section compared to the metal group (73.54μm, 46.5μm respectively) (P=0.000), while there is no statistical significant difference between the two experimental groups in proximal sections.
 
Conclusion: Non-bonded teeth have showed least demineralization compared to bonded teeth. Moreover, teeth bonded with ceramic brackets have showed significantly higher demineralization compared to teeth bonded with metal brackets.
