Abstract:
Root canal treatment is normally prescribed to treat an infection, and as with all surgical procedures an aseptic technique is essential throughout. Even after complying with the best of the treatment regimens a root canal therapy can fail due to the presence of certain resistant, residual organisms. This study is all about clinical efficacy of 2% chlorhexidine gel in reducing intracanal bacterial count during RCT instrumentation. A total of 138 patients participated in this study. The sample included 69 male and 69 female patients. The mean age of the sample was 28.3 (SD = 4.16). The mean baseline bacterial count was 4.51 x 106 as compared to post medication count after 15 days which was 2.88 x 106. Bacterial growth/positive culture was found in only 29.7% of patients. Furthermore, effectiveness of Ca (OH)2, 2% chlorhexidine gel as measured by 50% decrease in bacterial count was observed in 65.2% patients. The results of Ca (OH)2, 2% chlorhexidine gel in the present study was able to reduce bacterial count after 15 days. These results suggested that CHX gel might be more effective at curtailing bacteria, and thus be better suited as intracanal medication.

Abstract:
Horizontal ridge augmentation is very challenging procedure which requires primary closure to prevent early exposure of grafting material and membrane. To accomplish soft tissue closure, adjunct procedure such as releasing incisions, advancement of flaps, periosteal release, or scoring of the periosteum, are often required. These adjunctive procedures can compromise blood supply to the grafting site and eliminate keratinized tissue which is of great importance in implant survival. In this case series, a technique will be introduced which can achieve successful horizontal bone augmentation with simultaneous keratinized tissue widening by open membrane treatment modality. In this presentation, rh-BMP2 was used with non-porous teflon sheet to covering graft material with intentional open membrane technique. Basic surgical procedure is as follows: 1. Full thickness flap was elevated (split keratinized tissue if possible) 2. Decortication of recipient site was performed with round bur 3. Teflon sheet was trimmed to cover grafting material 4. Implant was placed based on prosthetically favorable position when primary stability can be achieved 5. Graft material is placed with gentle pressure (Autograft or Xenograft alone or mixed with allograft) 6. Short healing abutment (<2mm) is connected to implant to reserve space for soft tissue 7. PRF is placed and teflon sheet is covered. 8. 4-0 nylon suture is used without primary closure 9. Inject rh-BMP2 in augmented site 10. Suture was removed 1 week after surgery and Teflon sheet was removed 3 weeks after surgery 14 cases had successful result without any complication. 1 case failed due to heavy smoking. Autogenous bone harvested from chin or ramus showed more dense regeneration of cortical and cancellous bone according to cone beam CT evaluation than Xenograft and Allograft material. This case series suggested that the open membrane technique utilizing rh-BMP2 and teflon sheet can be used to recover horizontal bone defect with simultaneous keratinized tissue widening without primary closure.

Title: A Nouvelle approach for extraction socket healing and reservation
Biography:
Youmna has completed her MsC at the age of 28 years from Alexandria University and a diploma in Proffesional Healthcare Management from The American University in Cairo. She is an ass. lecteurer of Oral Biology and Dental Morphology at the Faculty of Dentistry, Ahram Canadian University in Egypt. She has managed to publish one paper at the Alexandria Dental Journal, and an E-poster in the 29th Annual American Dentistry congress. She is a young dedicated researcher in the field of bone regenration.
Abstract:
Studies concerning healing of extraction sockets revealed that sockets are filled with new bone by as much as two thirds in 40 days and completely filled with new bone in 10 weeks. There have been many studies demonstrating the bone-promoting effect of simvastatin local application in animal models. Simvastatin is shown to increase bone volume, bone formation rate, and bone compressive strength. The use of statins for bone regeneration is a promising and growing area of research. Statin drugs are mainly used in the treatment of high cholesterol since the discovery in the 1970s. The molecules produced by Penicillium citrinum, called citrinin and compactin (mevastatin), are potent inhibitors of an important enzyme 3-hydroxy-3-methylglutaryl-CoA reductase (HMG-CoA reductase) in the cholesterol production pathway.The first experimental evidence in an animal model of the osteo-modulador effect of statins was reported by Mundy et al who demonstrated that treatment with simvastatin resulted in a significant increase (up to 2–3 times compared with controls) in the rates and bone formation markers, and that the effect of statins were comparable to that induced by treatment with bone morphogenetic protein-2 (BMP-2) and fibroblast growth factor, which are known stimulants of bone metabolism. The aim of this study is to examine the influence of simvastatin on bone healing in extraction socket of first molar in rat mandibles, where the specimens will be processed for scanning electron microscopy, light microscopy and immunohistochemical detection of Vascular Endothelial Growth Factor and Fibronectin.

Abstract:
Since the concept of osseointegration was introduced by Brånemark et al., modern dental implants have been considered a safe and reliable option for replacing missing teeth. Even though implant dentistry is constantly evolving towards simplification of clinical procedures and shortened treatment times, with such developments as immediate implant placement. Recently, a novel approach for immediate implant placement design has been proposed to replace a (soon to be) missing tooth, in contrast to traditional immediate implant approaches using conventional, threaded, cylindrical or tapered implants; this technique provides a preemptively individually made root analogue implant (RAI). These customized dental implants not only preserve more hard and soft tissues but also reduce rehabilitation time and prevent the second surgical intervention, leading to overall cost reduction and an improvement in the patients’ psychological outlook for dental treatment. All that in mind, dental implants closely imitating natural root geometries are difficult to fabricate with conventional methods of computer numerical control machining because of the existence of irregularly curved surfaces and complex 3-dimensional (3D) geometry, however with the rapid development of implant materials and computer-aided design/computer-aided manufacturing (CAD/CAM) technology and also improvement of additive manufacturing (AM), also known as 3D printing, researchers are capable of directly producing almost any desired geometry without an expensive mold and tooling now. With the combined use of cone beam CT 3D data and high-end CAD/CAM technology it was possible to manufacture a RAI with sufficient precision. The custom-made implant resulted by combination usage of CBCT and CAD/CAM showed almost perfect functional and aesthetic integration. The possibility of fabricating custom-made, root analogue implants opens new interesting perspectives for immediate placement of dental implants. The aim of this present study was to review the different means of fabricating root analogue implants and their success rate.

Title: The effect of two nano filled resin-based coatings on color stability of five glass ionomer restoratives immersed in three different food simulating solutions
Biography:
Dana Jafarpur is a sixth year Dental student at Shiraz University of Medical Sciences. Next semester she will be graduating Summa cum laude from Shiraz Dental School and has written a book on Forensic Dentistry and published 5 papers during her undergraduate studies.
Abstract:
Objectives: To evaluate the effect of different nano filled resin coatings on the staining susceptibility of glass ionomer restoratives after immersion in three food simulating solutions (FSS).Methods: Five encapsulated glass-ionomer restoratives (Riva light-cure (SDI), Riva self-cure (SDI), Fuji II LC (GC), Fuji Bulk (GC), Equia Forte Fil (GC)) and two nano filled coatings (EQUIA Coat (GC) and G-Coat plus (GC)) were employed. All specimens were immersed in distilled water for 24 h and then subjected to a color measurement with a spectrophotometer. Then the samples were divided into three subgroups and immersed for another one week in lactic acid (0.1 mol/L), coffee and distilled water (control) respectively. The differences in the lightness and chromaticity values (ΔL, Δa, Δb) were determined and the total color change (ΔE) was calculated using the formula:
Results: Three-way ANOVA showed a significant interaction effect between materials, coatings and solutions for the color change values. Therefore, one-way ANOVA was used to compare different variables between the materials. Color change values (ΔE) varied depending on the material and solution. G-Coat Plus exhibited lower color change values compared to the EQUIA-coated and the uncoated groups. The effect of immersion in FSS on color change values among materials varied depending on the type of coating.

Title: Novel piperidone derivatives with the potential to treat oral cancer
Biography:
Dania Alkhani has completed her Doctor of Dental Medicine (DMD) at University of Saskatchewan College of Dentistry. She is working as Dentist in Ottawa, Canada.
Abstract:
Aim: The aim of the present study is to prepare novel lead compounds with CC50 values of less than 10 uM and SI figures in excess of 10. Oral cancer accounts for 1-2% of all cancers that may arise in the body and 90% of these oral cancers are in the form of squamous cell carcinoma (SCC). Currently, the main method of management of SCC is through Mohs surgery, which is an invasive and technique-sensitive procedure. The aim of this research is to synthesize compounds that are toxic to oral SCC and also display tumor-selective cytotoxicity. The hope is to create a more effective and less invasive method for treating SCC.Methodology: The prototypic molecule used is 3,5-bis(benzylidene)-4-piperidone (compound 1) which was synthesized by a literature procedure. From this juncture, four additional compounds, 2-5, were prepared which have different substituents on the aryl rings. These compounds were screened against three human cell lines of oral squamous cell carcinoma: HSC-2, HSC-3 and HSC-4. They were also assessed against human gingival fibroblasts, pulp cells and periodontal ligament fibroblasts which are non-malignant cells. Melphalan was used as the reference drug. From this data, the potencies and selectivity index (SI) figures (CC50 values against non-malignant cells/CC50 figures towards neoplastic cells) were determined.Results: Among the five compounds evaluated, compound 4 was the most potent with a mean CC50 value of 0.51±0.21 uM towards the malignant cells. It has an average SI figure of 6.4. Compound 5, although having an average CC50 figure of 22.3±4.3 uM, was the most selective with a SI value of >17.2.Conclusions: Since compound 4 was the most potent and compound 5 was the most selective towards malignant cells, a future goal is to prepare analogs of 4 and 5 bearing in mind the structural features of these two compounds. The aim is to prepare novel lead compounds with CC50 values of less than 10 uM and SI figures in excess of 10. Should these objectives be met, consideration for animal testing will be made.

Abstract:
The foundation for successful treatment planning is largely reliant on the ability of the clinician to attain an accurate and contemporaneous patient history and to carry out a meticulous clinical examination. Treatment planning should aim to fulfill the patient’s realistic expectations, provide an out-come that boasts functional and aesthetic success and where possible, utilize techniques that involve minimal intervention. Emphasis should be placed on actively listening to the patient’s concerns and attitudes. Golden Proportion is a mathematical concept applied in architectural design and engineering to study design proportionality in the beauty of art and natures. The terms ‘aesthetic zone’ and ‘smile zone’ are commonly used to denote the appearance of the teeth and smile. These zones have been shown to influence significantly factors such as social acceptability, self-confidence and professional prospects. It is paramount to undertake a meticulous assessment of the aesthetic zone during patient examination, so that you may best determine which features may require addressing while developing the treatment plan. It is important in the first instance to gain an insight into the personal perceptions of your patient concerning their dental and facial aesthetics and their expectations; there are certain proportions of both a facial and dento-labial variety that are accepted as being visually pleasing. These are can be referred to as universal concepts in dental aesthetic. Clinical evaluation of the aesthetic zone can be subdivided into an assessment of the following: Facial features; Lips and facial skin; Dento-labial and dento-facial relationships; Teeth and gingivale. Patient satisfaction can be achieved by different types of dental treatment plan such as, Tooth Whitening; Cosmetic Teeth Shaping: Also referred to as “enamel shaping,” the dentist can reshape the tooth by filling or removing some of the enamel; Tooth Bonding: This is a procedure that can be used to repair or improve the appearance of a tooth that has been badly stained, broken or chipped; Dental Veneers: Veneers are a thin shell made out of porcelain or composite; crowns.

Biography:
Dr. Naghme Talakoub received her dental degree from Azad University of Esfahan, Iran. She started working as a clinician from 2007. She had a poster presentation in AADR 2016 about the effect of using different bonding resins a on contaminated enamel and its effect on reducing the micro leakage before the application of fissure sealants, and is currently working with an oncologist, Dr. Farhad Ghadiri, on treating patients who suffer from Mucositis.
Abstract:
Introduction & Aim: Oral mucositis is a common and debilitating condition in patients who go through radiation and chemotherapy. It appears as small patches to extensive ulcerations and tissue necrosis in oral mucosa. The prevalence of mucositis is 40-100% depending on the type of the cancer and the therapy undertaken. The aim of this study is to evaluate the effect of the Low Level Laser Therapy (LLLT) on reducing the symptoms of mucositis.Methods & Materials: Between Dec 2009 to Aug 2011, 36 patients who underwent chemotherapy or head and neck radiotherapy were randomized to receive LLLT and standard drug treatment for mucositis that was a suspension mixture of AlMG-S, Diphenhydramine, Nystatin, Lidocaine and Sucralfate. To be included in the study, patients had to be over 18, have a histological diagnosis of cancer, non-smokers, have an ECOG performance status of 0 or 1 and have an oral mucositis condition that has brought them to office for treatment. 36 patients were divided into 2 groups: those who received laser treatment and the control group. 8 patients in each group (laser and control) underwent radiation chemotherapy, 10 patients in each respective group underwent chemotherapy. The mean age was 45 to 47. A diode laser, emitting continuous light at 660 nm, 100 mW with a spot size of 0.1 cubic cm, was utilized for this study. The LLLT treatment was applied daily immediately after the appearance of the symptoms of mucositis for the duration of five days. The application time per point was 5 sec and the total application time was 12 min.Results: Results showed that only one patient in the laser group had his treatment delayed or interrupted, while seven people in the control group had to postpone their treatment due to mucositis complications. Only two patients in the laser group needed to take opioids for their pain, while ten patients in the control group took opioids. Only two patients in the laser group needed IV hydration, while twelve in the control group had to get IV hydration due to compromised food intake. Three patients in the laser group received GCSF while seven in the control group received it. No patient in the laser group hospitalized due to mucositis, while three patients in the control group had to be hospitalized for additional care.Conclusion: It is conclude in our study that LLLT for oral mucositis due to radiotherapy or chemotherapy in cancer patients is effective and can alleviate the complications of the condition. Further studies need to be conducted in order for the treatment to become a standard care for the cancer patients suffering from mucositis.
