Abstract:
Although the development of electronic technology, electronic devices, such as cell phones or personal computers (PCs) have spread worldwide in recent years; however, there have been several reports of physical abnormalities occurring because of electro-magnetic waves emitted by such electronic devices. In addition, the incidence of adverse biological effects due to electromagnetic waves may be increasing. Such unpleasant symptoms are termed as electromagnetic hypersensitivity. This condition includes many symptoms, such as headaches, fatigue, tinnitus, dizziness, memory loss, irregular heartbeats, and dermatological symptoms, which are considered to be caused by electromagnetic hypersensitivity. Dental implants have spread worldwide in dentistry. The risks and complications reported are limited to local issues. However, sometimes, there are patients who complained of systemic symptoms after dental implantation. The aim of my presentation is to demonstrate that systemic symptoms such as lumbago, shoulder stiffness, neck pain, hip joint pain, and facial pain improved after the removal of well-osseointegrated titanium implants. The results suggest that harmful electromagnetic waves received by implants affect body conditions; however, to date, the underlying mechanisms have not been identified. Therefore, further research regarding the same is required.

Abstract:
Intentional replantation (IR) is a concept that has been known for over a thousand years, it is defined by Grossman (1966) as an atraumatic extraction of a tooth and its reinsertion into its socket immediately after endodontic treatment and apical repair is done extra-orally. Intentional replantation is a treatment option when more conventional forms of treatment and retreatment either fail or are impossible. Recent case reports have demonstrated that with good case selection, intentional replantation can be a reliable and predictable procedure. The two most important factors for successful intentional replantation procedures are short extraoral time and atraumatic extraction. Through case reports, the indications and contraindications for intentional replantation will be discussed. The updated procedures for this rarely used treatment will be presented.

Abstract:
Effective chemomechanical preparation of the root canal and optimal 3-d obturation have been recognized as the two ultimate goals of endodontic treatment, more particularly in teeth with necrotic infected pulp and apical periodontitis disease. The effectiveness of irrigation in the complex root canal system at the apical root canal remains the most critical therapeutic requirement to treat apical periodontits. Experimental approaches and clinical data showed that irrigation is the most effective way for eradication of the root canal bacteria (planktonic and biofilms). The characteristics of irrigation protocol, such as the solution flow dynamics and irrigant replacement, have been recently attracted attention as the key factors in successful treatment outcome. The aim of this study is to critically review observations in relation to the variation of morphology of the apical canal system in different tooth types, and the required profile of apical canal instrumentation. The cross sectional diameter of the apical part of the used hand and rotary files, need to be evaluated before application of the irrigation protocol. The instrumentation technique should also be selected on the basis of the desirable geometry of apical root canal preparation. Finally the optimal working length must be carefully determined and confirmed in order to decrease the risk of apical debris and irrigant extrusion. The apical root canal irrigation as a balance between effectiveness and safety is further discussed and conclusions are justified on the following subjects: 1. The desirable size of apical enlargement, 2. The optimal design (taper) of apical part of instruments and 3. Distance of irrigation needle from the apex and 4. The specific form of irrigation needle tip.

Abstract:
Aim: For many children’s medical and dental procedures, unfamiliar dental staff and treatment places are disturbing and stressful. Stress in children often makes them uncooperative. General anaesthesia is indicated for anxious uncooperative children or those who are disabled, immature or too young to undergo dental treatment by other means. Moreover parents’ separation while entering the operative room is a traumatic experience for children. Thus premedication such as midazolam is recommended to decrease child’s stress. In these situations the increased recovery time was considered as one of the midazolam side effects. There is no study that evaluated the effect of midazolam both in parents-child separation and recovery time in long dental procedure. The purpose of this study was to evaluate the effect of nasal midazolam premedication with placebo on parents-child separation and recovery times in uncooperative paediatric patients undergoing long-lasting general anaesthesia for dental procedures.
Materials & Methods: Study Design: This randomized, double-blind study was done on 60 uncooperative patients (ASA physical status I or II) aged 2-4 years who were scheduled for general anaesthesia for dental treatment. Group A received 0.2 mg/kg intranasal midazolam as premedication, and group B received the same volume of intranasal placebo 20 minutes before entering the operating room for general anaesthesia. General anaesthesia was done with the same method for all patients, then
parent-child separation and recovery times were compared between the two groups.
Statistical Analysis: Statistical significance was set at P≤0.05. Statically analysis was performed using SPSS version 17. Chi-squared and student t-tests were applied to analyse the data.
Results: We found significant differences in parents-child separation assessment between two groups. Nasal midazolam premedication had a positive effect on parents-child separation; but there was no significant difference between the two groups in terms of recovery time.
Conclusion: Premedication of nasal midazolam before induction of general anaesthesia did not prolong recovery time, but made the separation of children from their parents easier by showing a better behaviour.

Abstract:
Hypophosphatemic vitamin-D resistant rickets is characterized by persistent hypophosphatemic and hyperphosphaturia. This metabolic disorder causes deficient calcification of mineralized structures such as bones and teeth. One of the most important oral alterations elicited by this condition is the recurrent formation of spontaneous abscesses. These affect multiple caries or trauma free primary o permanent teeth and are related to a deficient dentin mineralization. We report a case of hypophosphatemic vitamin-D resistant rickets in a patient who reported multiple dental abscesses and who required treatment consisting in pulpectomies, pulpotomies and chrome-steel crowns in molars and composite resin in anterior teeth. The aim of the present article was to raise awareness on the characteristics of this disorder, as well as its treatment and dental considerations.

Abstract:
Endodontic pain diagnosis is similar to a puzzle-diagnosis and cannot be made from a single isolated piece of information. The importance of correct diagnosis and treatment planning must not be underestimated. There are many causes of facial pain and the differential diagnosis can be both difficult and demanding. All the relevant information must be collected; this includes a case history and the results of both a clinical examination and diagnostic tests. The practitioner should be fully conversant with the prognosis for different endodontic clinical situations, only at this stage the cause of the problem be determined, a diagnosis made, the appropriate treatments discussed with the patient and informed or valid consent obtained. The clinician must systematically gather all of the necessary information to make a “probable” diagnosis. When taking the medical and dental history, the clinician should already be formulating in his or her mind a preliminary but logical diagnosis, especially if there is a chief complaint. The clinical and radiographic examinations in combination with a thorough periodontal evaluation and clinical testing (pulp and periapical tests) are then used to confirm the preliminary diagnosis. In some cases, the clinical and radiographic examinations are inconclusive or give conflicting results and as a result, definitive pulp and peri-apical diagnoses cannot be made. It is also important to recognize that treatment should not be rendered without a diagnosis and in these situations; the patient may have to wait and be reassessed at a later date or be referred to an endodontist.

Abstract:
One of the recent trends in endodontics has been the development of bonded obturating materials, in an effort to provide a more effective seal coronally and apically. The bond strength of endodontic filling materials to dentin is important to maintain the integrity of root canal seal. Increased adhesive properties to dentin might lead to greater strength of the restored tooth, which may provide greater resistance to root fracture and clinical longevity of an endodontically treated tooth. Recently, adhesive obturation systems have been introduced in endodontics in an attempt to obtain a “monoblock” in which the core material, sealing agent and root canal dentin form a single cohesive unit within the root canal. This review discusses the materials utilizing dentin adhesive technology in endodontics, limitation to effective bonding, and possible strategies for improved materials in the future.

Title: Is type of impaction of 3rd molars a risk factor in the frequency of post-operative complications? A retrospective study undertaken in the Charles Clifford Dental Hospital, United Kingdom
Biography:
Abstract:
Aim: To investigate the relationship between the type of impaction of wisdom teeth and the incidence of post-operative complications of surgical removal of impacted third molars.
Methods: A retrospective study of 210 patients, who has had one or more of their impacted 3rd molars removed at the Department of Oral Surgery in Charles Clifford Dental Hospital was done by reviewing case notes to collect the incidence of post-operative complications and comparing them to the type of impaction identified on plain film radiographs. The information was collected from patients attending the hospital from the period February 2016 to June 2016.
Results: There was no significant difference between the type of impaction and the incidence of post-operative complications, (Kruskal-Wallis ANOVA p≥0.12). Alveolar osteitis (dry socket) was the most common post-operative complication (77.7%), with females and smokers at a higher risk compared to male and non-smokers. Surgical difficulty score of all four types of impacted wisdom (mesioangular, horizontal, vertical and distoangular) had no significant effect on the incidence of post-operative complications.
Conclusion: This retrospective study suggests that there is no relationship between the frequency of post-operative complications and the type of impaction of third molars.

Abstract:
Low level laser therapy (LLLT) still lacks a clinical application in human distracted mandibles, although it has a potentially positive effect and has been tried experimentally. Studies describing the use of LLLT on distracted mandibular bone in animals are numerous and support its use. Is the use of diode laser following mandibular distraction osteogenesis in the human useful as well as in animals? At the end of the lecture, the participants will have a clearer idea about the effect of low level diode laser on human distracted mandibles as well as how ultrasonography and panoramic x-ray are useful to evaluate distracted bone healing.

Abstract:
Aim: To determine the prevalence and characteristics of pneumatized articular tubercle (PAT) at computed tomography (CT), and to determine whether the presence of PAT is a predictor of larger pneumatized spaces of temporal bone.
Materials & Methods: A retrospective study was performed using axial, sagittal and coronal CT images of 225 patients who attended a private medical imaging centre. Age and gender were recorded for all patients and, for cases of PAT, laterality and types were also recorded. Temporal bone pneumatization was recorded based on three reference structures on axial images. The Chi-square and ManneWhitney U-tests were used.
Results: Of the 225 patients, 43 (9.55%) had PAT, of whom 24 were female and 19 were male. This difference was not statistically significant (p>0.05). The age range of the patients with PAT was 8-67 years. Of the 43 patients, 24 had unilateral and 19 had bilateral PAT. Fifteen cases of PAT were unilocular and 28 were multilocular. Cases of PAT showed larger pneumatized spaces of other parts of the temporal bone (p=0.0001).
Conclusion: It is possible that PAT is a more frequent condition than is commonly perceived. The degree of pneumatization of temporal bone can be estimated by the evaluation of the air cells around the articular tubercle. CT is highly recommended in patients with PAT undergoing surgical treatment to determine the exact size an relationship of PAT to other parts of temporal bone.

Title: Patients with cardiovascular pathology in the focus of the dentist
Biography:
Abstract:
It is the middle age and the third age patients that usually face pathologies of different course such as cardiac, endocrine, neurological but there are combined natured pathologies which need more attention and more importance in treatment for the patients who need dental surgical intervention. In this study, our attention is focused on the pre-treatment and post-treatment of the patients who suffer from a cardiovascular disease while prone to a dental surgical intervention. The purpose of the study is to specify, clarify and outline the codes and the regulations of interventions in this category of patients for the only purpose of getting the right treatment while in the outpatient ambulatory clinics/private offices rather than in the regional hospital. Surely, we have to assure the patients that the treatment offered is of high level of proficiency, meanwhile focusing on the reduction of the cost for the patient and for our health institutions. In these days, the continuous changes in the life style we lead, the huge change we see in the quantity and the quality of the food we consume every day followed by the increase longevity/life expectancy has made all of us aware of the high number of people that suffer from cardiovascular diseases.

Title: Management of class III malocclusion in growing children
Biography:
Abstract:
Class III malocclusion is a rare malocclusion. Treating it is one of the most complex parts of contemporary orthodontic practice owing to the difficulties in accurate growth prediction, longer duration of mandibular growth and long term retention requirements. Different treatment modalities for correction of developing class III malocclusion are orthopedic appliances, myofunctional appliances and combination of the two though rare. This presentation shows cases treated with face mask, reverse twin block and face mask reverse twin block combination. Five years follow up shows their results to be stable.

Abstract:
Statement of the Problem: An anterior open bite is a definite lack of contact, in the vertical direction, between the incisal edges of the maxillary and mandibular anterior teeth. Good results in terms of function, aesthetics and stability are usually difficult to be obtained when treating open bite malocclusions. The purpose of this study is to describe an original protocol developed in order to treat this kind of malocclusions successfully.
Materials & Methods: The new non-extractive protocol involves the smart use of several therapeutic means such as rapid maxillary expander, mandibular lingual arch and/or lip bumper, occlusal grinding of deciduous first and second molars, lingual grid, myofunctional exercises and fixed straight wire appliances.
Results: Cases treated using this protocol is described and their long term stability is assessed.
Conclusions: The proposed therapeutic protocol seems to give good results in terms of oral health, malocclusion correction, disappearance of relationship problems and stability seven years after the completion of treatment. Selective grinding of deciduous teeth, permits to obtain fast therapeutic results with minimally invasive and transitional effects for dental tissues. Its effect, coupled with rapid expansion of the palate, mandibular lingual arch, lingual grid and myofunctional exercises, allows bite closure, which is followed and completed by fixed Straight Wire appliances. Any functional deficiencies or bad oral habits must be detected and corrected after the end of treatment to ensure long-term stability.

Abstract:
Objective:
Fixed spiral wire retainers offer several advantages, however they are prone to breakages which may result in relapse. The aim of the present study was to identify the frequency and factors associated with failure of fixed spiral wire retainers.
Material and Methods:
A retrospective cross-sectional study was conducted using orthodontic files and dental casts of 126 patients from dental clinics of a tertiary care hospital. Descriptive statistics were applied to calculate the frequency and most common site of breakages. Chi-square test was applied to compare the frequency of breakages among age groups and different retainer spans. Independent sample t-test was used to compare the mean overbite in retainer breakage and retainer intact groups. A p - value ≤ 0.05 was considered as statistically significant.
Results:
The frequency of retainer breakage was found to be 53.1%. Maxillary retainer breakages were found in 41.3% subjects whereas mandibular retainer failed in 22.2% subjects. The mean survival time of retainer was 8.91 ± 4.57 months. The detachment of the retainer from the tooth surface was the most common occurrence (86%). The most common site of retainer breakage was maxillary canine (32.5%) and mandibular central incisor (12.7%). All the subjects who had retainers extending till maxillary molars encountered breakages.
Conclusions:
A longer retainer span is associated with a greater risk of breakage. Failure rate in the maxillary arch was higher than the mandibular arch. The most common sites were the maxillary canine and mandibular central incisor. The most common pattern was wire detachment.
