Implant placement marks the start of a chain of events in both the hard and soft tissues adjacent to the fixture. While earlier concepts have associated early bone loss around dental implants with physiological remodeling, more recent data suggests do not seem to support this notion anymore. Instead, early marginal bone loss is considered pathological and should be avoided or minimized. A multitude of factors have been suggested to be related to the prevalence and severity of early marginal bone loss around implants. These include placement protocol (submerged or non-submerged; crestal/supra or sub-crestal); loading protocols, implant's design and position, residual ridge's dimensions and the quality, width of the facial/lingual walls and the width and quality of the periimplant mucosa. Also, occlusal overload, crown-implant ration and implant's angulation, implants' diameter, flap versus flapless, mandibular versus maxillary implants and fixed versus removable implant supported restorations. Other systemic and environmental factors (smoking habits, diabetes, radiation therapy and past periodontal disease) were also suggested as possible risk factors. This presentation will focus on current knowledge regarding these variables and will try to highlight the currently available data along with many missing pieces in the puzzle. Finally, the ways to minimize this phenomenon will be discussed.

For a long time, the endodontics was stagnant and without great prospects, it was a specialty seen as tiring for the professional and somewhat uncomfortable and even frightening for patients. All this began to change with the advent of NITI systems (Reciprocating and Rotary), with them, the root canal instrumentation became faster and stimulated the emergence of new root canals obturations techniques, These changes brought about a gain of time, a standardization of results. The advances were not limited to the root canal instrumentation and the obturation, they also brought benefits in the treatment of dental perforations, parendodontic surgeries and apical plugs with MTA. There were also advances in magnification with the lenses and especially with the microscope that allow the placement of channels, the visualization of separate instruments and perforations. Facilitating the treatment of each of these situations with the aid of ultrasonic tips of the last generation. And finally the appearance of the cone beam tomography that brought endodontics the possibility of seeing beyond the radiographic image. Because of all this, a better working condition for the endodontist, who ceased to be a sculptor and works with effective tools that did not require so much time of training and psychomotor improvement and the patients have access to faster and better-performing treatments with more comfort.

Orthognathic surgery is gaining more positive response in India over the recent years owing to the increase in awareness to facial esthetics as the priority in undergoing treatment for skeletal malocclusions. Worsening of facial appearance during the period of pre-surgical orthodontics has been the reason for shift towards a surgery, first approach in the management of dentofacial deformities. A universal method for the use of surgery, first process is difficult to adapt as most patients worldwide treated by “surgery first” approach belong to skeletal Class III malocclusion. On the contrary, the Indian population showed diversity in ethnic facial pattern and presented more skeletal Class I and Class II malocclusions. The objective of this paper is to highlight  ifferences in treatment planning and execution of surgical first approach in severe skeletal Class I, Class II and Class III malocclusions and compare them to the conventional orthodontics first approach through ideal clinical scenarios and critically evaluate the early results achieved.

Introduction: The PRF (Platelet Rich Fibrin), PET (Partial extraction technique) also known as socket shield technique and incorporating everything the CTO Technique (Coronal Trans-Odontal Technique). These are three different procedures in the literature and refined to use together for better bone preservation. With all allogeneic materials other than the implant reducing cost and chance of rejection. Use of biological growth factors and ideal placement of the implant preparing the anatomical tooth before using the same as a guide for immediate placement all proves to be promising in osseointegration and bone preservation. All procedures were performed between two privately owned offices by the same surgeon. Methods: Pre and Post CBCT used for comparison. Only patients with conditions which contraindicated the placement of implants and without medical clearance were not treated. Results: Total of 39 implants, 30 Maxillary, 7 mandibular, 2 deciduous performed. 1 failure (97.4% success) after 2 years in function. Conclusion: Use of PRF was a breakthrough in implant dentistry. Socket shield technique proves to be another positive influence in Implant dentistry by helping prevent bone loss. The CTO Technique performed by two private clinics in NY proves to help properly place and implant the same day without the use of static guides. Use all three procedures prove to enhance osseoingration and proper placement of an implant in 3 dimensions.

The conventional crestal implants are indicated in situations when an adequate vertical bone supply is given. These crestal implants function well in patients who provide adequate bone when treatment starts, but prognosis is not good as soon as augmentations become part of the treatment plan. Augmentation procedures tend to increase the risks and costs of dental implant treatment as well as the number of necessary operations. Patients who have severely atrophied jaw bones paradoxically receive little or no treatment, as long as crestal implants are considered the device of first choice. Basal implants are used to support single and multiple unit restorations in the upper and lower jaws. They can be placed in the extraction sockets and also in healed bone. Their structural characteristics allow placement in bone that is deficient in height and width. Basal implants are the devices of first choice, whenever (unpredictable) augmentations are part of an alternative treatment plan. The technique of basal Implantology solves all problems connected with conventional (crestal) Implantology. It is a customer oriented therapy, which meets the demands of the patients ideally. In this presentation the indications of using basal implants and the differences that exist between basal implants and crestal implants are discussed along with a case report.

According to most authors, red flat lichen (RFL) is observed in many countries. Its prevalence ranges from 0.1% to 20%. The

incidence rate in different climatic geographic regions has signif-icant variations: from 45% in France, up to 0.13%-0.34% in

Sweden; In India, it is 1.4%. In the Republic of Kazakhstan, the frequency of the disease is 450: 100,000. The main place in the frequency

of localization of RFL is skin. Observations conducted indicate that of the 374 patients with RFL, there were manifestations of

oral mucosa in 54% of patients, while in 26.5% it was isolated. More recent studies show a lower incidence of RFL lesions in the oral mucosa: out of 585 patients, 22% of patients had eruptions on the oral mucosa, only 13.5% had an isolated le-sion of the oral mucosa alone. Red lichen is more common in people aged 30 to 50 years, in women more often than in men. Men get ill somewhat earlier (30 years) than women (40 years). The same researchers showed a tendency to "rejuvenate" this disease, which is probably due to the growing unfortunate environmental situation and the pace of life, coupled with a constant  sychoemotional stress. We have tested the effectiveness of the use of a   olysaccharide film and apparatus for phototherapy in the complex treatment of RFL. The effectiveness of treatment was evaluated in the immediate and long-term (12 and 24 months after treatment) for the dynamics of the pain syndrome,

the timing of epithelialization of lesions, the average duration of treatment,  hanges in cytological and immunological parameters, the frequency of relapse or exacerbation of the disease.

Background: Using video eyeglasses as an audiovisual distraction is useful in managing anxiety and reducing fear and anxiety in

healthy children during dental treatments. Dental anxiety has a significant impact on cooperative behavior during the dental visit,

particularly in children, and it could impede, or even preclude, the dental treatment. For these reasons, a knowledge of the appropriate

guidelines of behavioral management of children plays a key role in the oral health promotion and represents a major topic in

pediatric dentistry. Distraction is the technique of diverting the patient's attention from an unpleasant procedure.

Aim: The aim of this study is to evaluate the effect of audiovisual distraction on behavior and self-reported pain of children during

dental restorations and its influence on the operator stress and the time of the appointment.

Material & Methods: This randomized controlled crossover trial study of 96 outpatient’s healthy children under 12 years requiring at

least two dental fillings. The written informed consent for participation and publication was obtained from parents/legal guardians of each patient in full accordance with the ethical principles of the Helsinki Declaration. First dental filling was done wearing the videoeyeglasses and other one using conventional behavior management techniques. Subjective and objective pain was evaluated using the Faces Pain Scale - Revised (FPS-R) and the revised Face, Leg, Activity, Cry, and Consol ability scale (r-FLACC). The operator stress using a VAS, the time of the appointment, and the child satisfaction was recorded and tested by paired t-test. Results: Using video eyeglasses, significantly reduced the operator stress. The bivariate analysis showed that the mean FPS-R score and the mean r-FLACC score were significantly lower using the video eyeglasses, only during the second clinical session. Conclusion: Audiovisual distraction could be useful in managing anxiety in children but cannot replace the conventional behavior management techniques.

Introduction: Bone-anchored maxillary expanders have been invented in order to provide extreme Pure skeletal expansion. There are studies that address the clinical effectiveness and outcomes of bone-borne maxillary expansion, but they were done mostly on adult subjects with surgical assistance. Objective: The main aim of this paper is to review publications that studied the effectiveness of bone-borne maxillary expansion compared with tooth-borne maxillary expansion in mixed dentition subjects. Search Strategy: A literature review using relevant articles dated from 2006 to June 2016 on PubMed and B-on databases was conducted. Relevant data were extracted, grouped and analyzed concerning three areas of research: the skeletal vs. dental expansion, side effects, and long-term stability of Tooth-borne maxillary expander (TBME), and Bone-borne maxillary expander (BBME). 16 articles were selected: 11studies addressed TBME; one study was a comparison between TBME and BBME, while the remaining 4 studies addressed BBME. Discussion: The outcome of the literature review showed that the percentage of skeletal expansion and dental expansion varied between TBME and BBME. Moreover, it also varied within TBME itself in different studies. Inter-coronal widths of maxillary permanent molars and first premolars in TBME were significantly greater than their counterparts in BBME. Generally, TBME showed a reduction in alveolar bone thickness on the buccal aspect of the banded teeth. Buccal tipping measured in TBME studies was small or high reaching up to 19 degrees, whereas in BBME group it was clinically trivial. Six months retention period is essential for recovery and long-term stability. Conclusion: Current available reviewed studies and clinical trials led to different inconsistent conclusions regarding the claim of the superiority and effectiveness of bone-borne versus tooth- borne maxillary expansion on mixed dentition patients. They were mostly done on adolescents or adults with surgical assistance. Although theoretically and logically this claim may seem valid, no evidencebased conclusion could be made since they were not done on patients below the age of twelve. Thus, future investigations on mixed dentition patients are highly recommended.
