The aim of this study is to prove the effeteness of this devise that have been developing. The ultrasonic excavator will be easily used to penetrate in caries and defective dentine which will decrease traumatic injury through connecting ultrasonic wave to excavator tip.

Objectives: Remove the caries and defective dentine with less trauma, and laceration to the pulp tissue, also, to reduce heat generation, vibration, noise and the hand pieces pressure applied on the tooth that come from air driven by using ultrasonic excavator According to Laird and Walmsley in the solution for all problems that are mentioned above.(1991) it is possible to use ultrasound without the resource of analgesia. And according to A.g.Antonio, L.g.primo and L.c.maia (case report 2005) the ultrasonic technique is the only one able to remove carious dentine without the formation of a smear layer and the consequent obstruction of dentinal tubules, and in same case report he said about using the ultrasonic technique for caries removal it is provides more safety during the treatment and offering comfort to the patient. And according to Ming-shu l (2013 animal study) if we make perforation on a tooth by ultrasonic device is better than making it by air driven handpieces based on the bleeding level, histologically and time to become a necrotic pulp after perforated. As conculsion: According to my experience when I used the ultrasonic excavator to excavate the caries and defective dentine for two molars extracted teeth, it proved to me the devise can removed a caries and defective dentine. But the device under development and there is a trial version of it and also I have patent application from Saudi patent office, number 116380118.

The main goal of root canal treatment is total eradication of the microorganisms to attain bacteria-free environment both in the tooth and at the apex, including the periodontal tissue and the surrounding apical bone to favor the environment for healing without the need of periapical surgery in some resistant cases. Recently the use of lasers has gained an increased interest in the endodontic field due to its bactericidal effect and bio-stimulation effect. In this case report, five cases diagnosed with necrotic pulp and periapical lesion were selected. A CBCT scan for each patient to verify the size (5-10 mm) and bone density of the periapical lesion preoperatively. Microbiological samples were taken after accessing the root canal, after conventional root canal treatment and after canal irradiation with diode laser (980 nm) coupled with the optical fiber 200 μm to assess the bacterial count after each procedure. A second CBCT scan was taken for each patient at 6 months follow up to evaluate the healing process. Complete eradication of the bacteria after canal irradiation with diode laser was obtained. The evaluation of the CBCT scan showed decrease in the periapical lesion size and increase in its density after the 6 months follow up. It can be concluded that laser therapy may be used as an adjunct to conventional endodontic therapy to improve the treatment quality of infections of the oral cavity. This may lead to save the patients from the invasive surgical intervention.

Practical Application Of Lasers In Every Day Dentistry

 

Background: In the past decades the concept of “Laser applications in Dentistry“has been established. This new concept implies several changes to widely adopted “cut and suture” and radical strategies when managing the caries and gingival procedures. New generation of Erbium and diode lasers have been introduced to dental clinics with very high success and patient acceptance rates. What can’t not be solved using the traditional treatment, laser can be a good choice to resolve it.

In this lecture we will discuss the details of lasers application of hard and soft tissue lasers

1. What are the advantage of using laser over the traditional treatment

2. Hard tissue applications of lasers in dentistry

3. Soft tissue application of lasers in dentistry

4. Clinical cases presentation

5. Low level laser therapy from science to practice

 

Methods: A recent review about the use of lasers in dentistry was conducted .

 

Results: Dentistry today is evolving tremendusly and the use of lasers in dentistry is a double –edged sword : if it is properly used, laser can be an initial and/or additional tool in our daily practice , whereas if it is misused it can lead to catastrophic results.

Currently, her research is related to know the frequency of HPV infection and its association with head and neck tumors, identifying the HPV genotypes, the expression of viral genes and cellular proteins. Her expertise in Public Health Education, specially with elderly patients came after some years of experience in research and teaching both in hospitals and education institutions.

In Brazil, 8.6% of the total population is 60 years old and most of them consume 60% of the national production of medicines. Due to the mouth-related (oral) side effects of medications and its impact on public health, the aim of this study was to analyze the association between salivary flow and the use of medications in the elderly, as well as to enquire if patients who use medicines were told about the possible side effects in the oral cavity. Methodology: This research was a case study (n = 30) of people aged over 60 that attended the dental clinic of Herrero School of Dentistry, approved by the ethics committee of the institution. Unstimulated saliva samples were collected and data were obtained through a questionnaire, after application of IC. Salivary volume flow and pH were assessed, and data were subjected to statistical analysis with p = 0.05 significance level. Findings: None of the patients in this study had ever received any professional information about possible oral side effects of medication. The results showed that the salivary flow of 59.37% of the sample was between 0 and 0.25 ml / l and that 68.75% had a pH between 6.1 and 7. The use of some medication was reported by 78.1% of the sample and the all the 14 pharmacological groups indicated were significantly associated with changes in the oral cavity such as dry mouth, difficulty swallowing, chewing and difficulty swallowing solid foods.

The aim of this study was to simplify the optimal temporal areas for safe and reproducible approach for BoNT injections into the temporalis muscle(TM) by carrying out detailed dissections and measurements of the structures in the temporal area, and to virtually represent a topographic mapping of postural relations among the major anatomical structures such as superficial temporal artery, middle temporal vein and temporal branch of the facial nerve in the temporalis muscle of the temporal area. Nineteen sides of TM from 10 embalmed Korean cadavers were used in this study. The lateral canthus of the eye and tragus were set as landmarks to establish the reference line of this study. The topographies of the superficial temporal artery, middle temporal vein, temporalis tendon, and the temporalis muscle were evaluated. On the disclosed boundary of the muscle, we can visualize an imaginary, rectangular TM in the temporal area. The surface of TM can be divided into 9 equally sized rectangular areas. The topography of studied anatomical structures in these nine compartments was observed and measured from the superficial to deep layers. After drawing the muscle boundaries, they were divided into nine compartments in order to simplify the relationship between the soft-tissue landmarks and the anatomical structures, and to more facilitate the description of appropriate injection sites. The relative positional ratios between the anatomical structures were constant in all of the specimens. The reference line was first established as C–T, and the distance between C and E' was set as the bottom side of the TM rectangle. The vertical sides of the rectangle were configured at 80% of the bottom side(ratio 5:4). Based on the results of this study, Am, Mu, and Pm were proposed as suitable BoNT injection sites. (figure)

Mohamed Mohsen Abielhassanan is an assisstant lecturer at the department of Endodontics, Faculty of Dentistry Cairo University. He completed his Masters Degree at the age of 28 years in 2017. He is a Staff Member at the Department of Endodontics, Cairo University. Both started to conduct a series of Lectures targeting the merge between recent evidence based studies and clinical tips and tricks that lead consequently to better outcomes and help to achieve the goal of Endodontic treatment despite the difficulty or challenge faced by the operator.

 

The variation and difference in morphology and configuration of pulp and root canal space creates challenges in everyday endodontic practice. This diversity dictates unique and customized treatment plans for various cases. Despite the breakthrough in techniques and instruments used in the field of Endodontics, yet still the clinical tips and tricks provide a clinical guideline and more convenient ways to deal with various challenges. In this lecture, we are going to discuss some of the clinical challenges faced by the endodontist or general practitioners in daily practice.Broken files represents one of the most difficult challenges faced in Endodontics. To manage a broken file it needs a solid base of scientific knowledge about lines of treatment in addition to high skills of the operator. So how to avoid files’ separation and how to deal with broken files in a simple and step by step protocol. Open apices are also one of the obstacles faced by the endodontist, different modalities of treatment as apexification or surgical intervention with MTA plug application. With the breakthrough of tissue engineering and revascularization an alternative line of treatment has been introduced, that affects prognosis and success rate of cases and solve various complexities of previous lines of treatment. How to avoid files’ separation and how to deal with broken files. Calcified canals and how to deal with calcifications of root canals using different mechanical tricks. Finally, the detection and management of extra root canals that affects the prognosis of daily endodontic cases and may lead to subsequent failures. This lecture has been awarded the best clinical and evidence based lecture in the fifth international Dental congress in Egypt in April 2017.

Introduction: Inverted smoking habit consists of the technique of placing the burning part of the tobacco inside the oral cavity, generating multiple lesions, most of them with a tendency to malignize oropharyngeal cancer. This habit is common in South America, Sri lanka and India.

Objective: The aim of the study is to identify oral lesions caused by smoking habit in rural populations of Colombia.

Methodology: A cross-sectional descriptive study was carried out, 23 patients with a history of this habit were studied, they underwent a stomatological exam, anamnesis and biopsies.

Results: Several manifestations in the oral cavity are evidenced, in close relation by the practice of such habit, such as nicotinic palate, leukoplasia and squamous cell carcinoma. The etiology of this practice is considered related to cultural beliefs.

Conclusions: The practice of this habit tends to cause multiple manifestations in the oral cavity, among them cancer in high percentage, it is considered important the education of this population, in addition to its initial treatment, also the dissemination of these results is important for the global academic community, to prevent fatal consequences.

Suturing lacerations in accident and emergency departments within hospital is a crucial part of working in the Oral and Maxillofacial Surgery Department. For a trainee, it is important to learn about the anatomical landmarks of the face, layers of soft tissue and general treatment and management of patients who present with lacerations of the head and neck region, to achieve the best functional and aesthetic results. I will present a series of 5 case reports with photographs where lacerations have been sustained by patients attending the emergency department. The treatment delivered to these patients are dependent on a number of factors: Mechanism of injury, depth of laceration, any involved structures, patient background (including medical history) and a simple guide for those early in their training, including the benefits of prescribing chloramphenicol eye ointment 1% for use on the wound for 7 days, and supporting evidence, indications for antibiotic cover and use of haemostatic agents to control bleeding.

Aim: Temporomandibular joint internal derangement (TMJ-ID) is the imbalance of metabolic processes in the extracellular matrix (ECM) of the articular disc, which progressively degrades causing tissue breakdown. The Vitamin D receptor (VDR) gene polymorphisms have been investigated for their potential effects and functional significance on several pathological conditions particularly osteoarthritis (OA) and disc degeneration-linked pathologies. The aim of this study was to investigate the possible association of Fok1, Apa1 and Taq1 polymorphisms of VDR gene with TMJ-ID.

Materials and methods: The study included 49 unrelated TMJ-ID patients (31.7 ±7.9) and 70 healthy controls (28.22 ±5.9) without TMJ-ID. Additionally, TMJ-ID patients were evaluated as anterior disc displacement with reduction (ADDWR) (n=24) and anterior disc displacement without reduction (ADDWOR) (n=25). Blood samples were obtained and DNA was extracted by standard proteinase K/phenol-chloroform method. Fok1, Apa1 and Taq1 polymorphisms of VDR gene were investigated by a polymerase chain reaction (PCR) based restriction fragment length polymorphism (RFLP).

Results: The genotype and allele frequency distributions of Fok1/rs2228570 (C>T), Taq1/rs731236 (T>C) and Apa1/ rs7975232 (A>C) did not show significant differences in TMJ-ID patients compared to the healthy group. In Fok1, carrying the TT genotype was almost 2 fold risk factor in TMJ-ID, ADDWR and ADDWOR patients compared to the healthy group (OR=1.72, OR=1.55, OR= 1.93 respectively) although not significant. In ADDWR, CT genotype was significantly different

than CC genotype (OR=0.35, CI:0.12-1.02, p<0.05) as a protective factor. In Apa1, carrying the AC and CC genotype was almost 1.23-1.79 fold risk factor in TMJ-ID patients, in ADDWR and ADDWOR cases compared to the healthy group although not significant. There were no significant results in none of the groups in Taq1 polymorphism.

Conclusion: Our results suggest that Fok1 and Apa1polymorphisms may be associated with TMJ-ID pathogenesis. Increasing the case and controls numbers is needed to further evaluate the genotype and allelic frequencies and risk factor ratios of VDR

polymorphisms in TMJ-ID.

After extraction of the teeth, the alveolar bone goes through the remodeling process, which leads to horizontal and vertical bone loss. These reabsorption processes complicate dental rehabilitation, particularly in connection with implants. Careful management of post-extraction tissues is necessary to preserve the alveolar ridge. Several methods of guided bone regeneration have been described to retain the original bone size after extraction. Most procedures use filling materials and membranes to support the oral plaque and soft tissues, stabilize the clot and prevent epithelial growth. Instead of surgical augmentation to correct a defect peak, the socket-shield technique offers a promising solution. With this method, it will be demonstrated how the crest and the entire buccal bone are clinically preserved and the biological integrity of the buccal periodontium remains untouched. This method has also been described in connection with the immediate placement of the implant and the provisional crown. The immediate postoperative period, as well as the follow-up of one year, will be demonstrated as a functional and aesthetic result of the treatment. The socket-shell technique is a highly promising addition to clinical implant dentistry. We will discuss the possibilities, limitations, and guidelines for future research that we begin at our university.

Missing upper anterior deciduous teeth may be caused by trauma or due to extraction as a result of extensive carious attack. The premature loss of anterior dentition may affect eating, speech development and behavioral problems. The parents' attitude toward restoration of damaged, unaesthetic or missing anterior teeth is very positive and may influence the final treatment. Several attempts to restore missing anterior teeth using polyethylene fibers were published with positive results. The use of glass fibers as a frame for restoration of missing permanent teeth showed success rate of more than 90% after 5-20 years. The use of glass fibers in pediatric dentistry poses several problems to the clinician: 1. the small size of the crowns that reduce the area of bonding. 2. the adhesive procedure which is affected by the thick a-prismatic layer of the deciduous teeth. 3. the length of the chair side procedure that is affected by the child age and tranquility. The aim of the study was to establish the optimal bonding procedure and bonding material for adhesion of glass fibers frame to deciduous teeth and to develop a method of preparing a preformed rigid frame for restoring missing upper anterior deciduous teeth. The presentation will show the results of the laboratory study and the clinical implication of the procedure with long follow-up periods.

The objective of this cross-sectional study was to determine the reliability of foveae palatinae for locating the position of the vibrating line in edentulous patients. The study was conducted in a tertiary care dental hospital in Islamabad, Pakistan on a sample of 150 completely edentulous patients. Clinical examination of the soft palate area was conducted to assess for the location of the vibrating line, whether it was at, anterior or posterior to the foveae. Interestingly, foveae were not present in 27.2% of the sample. 32.5% patients had foveae present at the level of vibrating line, 31.1% had vibrating line posterior to foveae palatinae, while only 8.6% presented with vibrating line anterior to fovea palatinae. Within the limitations of the present study, it was concluded that foveae palatinae are not a reliable anatomical landmark for determining the position of the vibrating line.

From being one of the dentists; I have been thinking for creating an instrument to help in restoring the most difficult types of dental caries, (CLASS II Cavity), because it is a caries related to the teeth adjacent to it, which make it difficult to restore it and for that reason we are using an instrument in restoring this type of caries. So in which that instrument be easier, flexible and integrated than what is now available in dental clinics. Therefore, when looking to the instruments which are using in dental clinics now-a-days for restoring (CLASS II CAVITY), we find dis-advantages including the following: Most of it does not take the form of tooth curvature or not formed on the form that required to make the filling compensates of caries of the tooth properly and intimate fit to the composition of the tooth, which prevents future caries due to lack or increase the filling of the caries cavity as well as do not maintain the distance between teeth, making it difficult in using of dental floss and so on. And most of these instruments cause injury and damage gingival structure due to a thickness of the unit of these instruments and its types are completely incompatible with the gingival pockets, which is necessary to allowing entering these instruments, especially if the caries is under CEJ. The innovative instrument has the following characteristics: It has a strong ability to form around the tooth, which gives a great ability to take the form of filling cavity only, which makes it easy to keep the distance between the teeth to be cleaned and thus prevent the occurrence of any subsequent caries. And does not cause any injuries to the gingiva because it is too thin and sharp so easily flow it in the pockets of gingiva, especially When decay is below the CEJ line .And also the instrument is hydrophobic, which helps to prevent the arrival of liquids to the cavity and this is important for the success of filling. Marketing quality is possible because this instrument is disposable material and very symbolic value also I has been formed a good number of them and use it in phantom, which proved the feasibility of the idea and its effectiveness.
