Abstract Vertical condensation of gutta-percha is one of the frequently used techniques of hermetic and three-dimensional obturation of root canal system which is one of the primary goals of endodontic tooth treatment. Techniques for filling root canals have been described since ancient Egypt and have undergone dynamic development in recent decades. The aim of the article is to analyze the technique of obturation of root canals using vertical condensation of guttapercha and to point out its benefits and pitfalls. The poor-quality treatment of the tooth deteriorates its prognosis, function, and long-term survival in the oral cavity; thus, the hermetic obturation of the root canals is one of the most important pillars of the complex tooth treatment. Obturation of the root canals by vertical condensation of warm gutta-percha is nowadays considered in the correct indications as one of the most commonly used techniques in the excellent dental practices. Even though it is quite technologically challenging and time-consuming it enables to reach high level of predictability and clinical success. Currently, the obturation technique based on master gutta-percha cone combined with the calcium-silicate based sealer is emerging. However, long term results of clinical studies and follow-up are needed to make a significant improvement in the area of endodontics.

AbstractObjectives:The three-dimensional anatomy and conspicuous location of the nasal tip makes it one of the most challenging sites of facial plastic surgery. This article reviews literature on nasal tip sculpture using suture techniques, as well as the authors' own experience.Methods:A search was conducted using Pubmed, the Google internet search engine and the authors' files, using the keywords ‘nasal tip’, ‘suture’, ‘rhinoplasty’ and ‘septorhinoplasty’.Results:Common nasal tip suture techniques and suture algorithms are presented, along with a summary of the indications and side effects of each technique.Conclusions:Predictable long-term results are more likely to occur with minimal local tissue excision. Suture techniques remodel the shape of the nasal tip by altering the configuration of, and the relationship between, the tip cartilages and their supporting structures; they also preserve nasal tip anatomy and limit resection. Intra-operatively, the effects are immediately visible, and can be adjusted or reversed. Tip sutures should therefore be considered instead of tissue excision whenever possible.

Purpose: The objective of this investigation is to study prosthodontics and internal components resistance to the masticatory stress and considering different force directions by using Finite Element Method analysis (FEM). The structural materials of the components are usually Titanium alloy grade 4 or 5 and thus, guarantee the integration of the fixture in the bone due to the osteointegration phenomena. Even if the long-term dental implant survival rate is easy to be obtained and confirmed by numerous researches, the related clinical success, due to the alteration of the mechanical and prosthodontics components is still controversial. Methods: By applying engineering systems of investigations like FEM and Von Mises analyses, it has been investigated how dental implant material was held against the masticatory strength during the dynamic masticatory cycles. A three-dimensional system involved fixture, abutment and the connection screws, which were created and analyzed. The elastic features of the materials used in the study were taken from recent literature data. Results: Data revealed a different response for both types of devices, although implant neck and dental abutment showed better results for all conditions of loading while the abutment screw represented aweak point of the system. Conclusion: The data of this virtual model showed all the features of different prosthetic retention systems under the masticatory load. Clinicians should find better prosthetic balance in order to better distribute the stress over the component and to guarantee patients’ clinical long-term results.

The authors analyzed long-term follow-up data to assess the value of intracavitary irradiation with stereotactically implanted beta-emitting radioisotope 90Y-silicate colloid for the treatment of craniopharyngiomas. Fifty-seven craniopharyngiomas in 42 patients were selected for retrospective analysis. The yttrium-90 was implanted intracavitally, using computerized tomography-guided and three-dimensional stereotactic treatment planning. The cumulative dose aimed at the inner surface of the cyst wall was 300 Gy. An average of 75% shrinkage of the initial cyst volume was observed. In 18 cases the reduction was more than 91%, and the cyst disappeared totally in 11 cases. A 50% decrease in cyst volume was usually apparent between the 2nd and 4th months. A 70% decrease in cyst volume was seen by the 5th and 6th months and an 80% reduction by the 7th and 8th months. Cysts that were unchanged remained so throughout the observation period. The time course of volume reduction could be expressed mathematically by the formula of 0.73 X e-0.62 X T + 0.27, where “e” is the basic number of natural logarithm and “T” is the time expressed in months. Mean survival duration after intracavitary irradiation was 9.4 years. The shrinkage of the cyst was a consequence of fibrosis of the wall, as seen on histopathological examination. The neuroophthalmological prognosis was favorable only when the optic disc was normal or nearly normal at the time of the treatment. In the presence of preexisting optic atrophy, visual deterioration proved to be irreversible. The long-term results support the view that intracavitary90Y-irradiation is a noninvasive and very effective method of treatment for craniopharyngioma cysts. Because of the 1.1 mm half-life decay of beta irradiation, it cannot influence the solid part of the tumor; therefore, the best result can be expected in solitary cysts.
