The aim of this study was to evaluate the interradicular septum bone morphometric characteristics using cone beam computed tomography (CBCT) images, as well as to establish quantitative shortcuts to allow clinicians to make a faster and more reliable plan for immediate implant placement in the maxillary molars area. This retrospective quantitative study was conducted on CBCT images obtained from 100 patients. The morphometric analysis of the maxillary molars region was based on the parameters obtained on the sagittal and axial slices. The analysis performed on sagittal slices showed that the first maxillary molars had a wider interradicular septum when compared to the second molars, but the septum height in the first molars was significantly below the height in the second maxillary molars. The axial CBCT slices analysis showed that both interradicular septum perimeter and surface area were significantly more pronounced in the first than in the second maxillary molars. The interradicular furcation angle significantly correlated with the surface area (positively) and septum height (negatively) for both molars. The results of this study may recommend CBCT image analysis as a useful tool in predefining the circumstances that can allow for substantially better planning of immediate implant placement procedures in the region of maxillary molars.

Background/Aim. Inappropriate prescribing of antibiotics to the patients with acute bronchitis is frequent event in clinical practice with potentially serious consequences, although majority of treatment guidelines do not recommend it. The aim of this study was to reveal risk factors associated with inappropriate prescribing of antibiotics to the patients with acute bronchitis in primary healthcare. Methods. This case/control study included the adult patients with acute bronchitis during the initial encounter with a general practitioner. Prescription of an antibiotic was an event that defined the case, and patients without prescribed antibiotic served as controls. Results. Antibiotics (mostly macrolides and beta-lactams) were prescribed to the majority of patients with diagnosis of acute bronchitis (78.5%). A significant association was found between antibiotic prescription rates and patient age, whether an attending physician is a specialist or not and the average number of patients a physician sees per day [ORadjustedwas 1.029 (1.007-1.052), 0.347 (0.147-0.818) and 0.957 (0.923-0.992), respectively]. Conclusion. When there is primary care encounter with patients suffering from acute bronchitis, older patients are more likely to receive inappropriate antibiotic prescription, especially if their physician is without specialist training and has less patient encounters in his/her office daily.

The interradicular septum describes area in the root furcation that separate alveoli of multi-rooted teeth. The shape and dimension depend of the topography of the extraction socket, the geometry of residual root and anatomy of molars alveoli. The clinical implications of this anatomic structure may be used in oral surgery resection procedures, periodontology and implantology. There is an opinion from the surgical and prosthodontic side that center of interradicular septum may be adequate place for immediate implantation. The aim of this study was to investigate morphological characteristics and clinical implications of upper molars interradicular septum. The studies showed that interradicular septum is important for success of resection surgery procedures: hemi-section, bisection and root amputation. It’s reported that furcation involvement in periodontal disease is clinical sign for severe bone loss. By reviewing the available literature for immediate implantation, it’s reported the clinical implications for diagnostical plan (pre-intervention), presurgical (pre-instrumentation) and intraoperative evaluation of interradicular septum for immediate implantation. The cone beam computed tomography analyze study presented mean values of septum height and wide for hypothetical plan of immediate implant placement. The presurgical studies evaluate how to assure preservation of septum and safe implant position in center of septum. The research showed varies therapy modalities that can be used, and how to choose right therapy according the socket type and initial septum width classification. According to observation of studies results, other researches should be considered for CBCT anatomical structure analyze and measures of interradicular septum for immediate implantation planning.

Replacement of deciduous teeth with permanent teeth is a physiological process, and as a consequence of early tooth loss in deciduous or mixed dentition, loss of space may occur. There is no doubt that the loss of space after the premature extraction of deciduous molars occurs, however, the width of the lost space and the need for their clinical use are still a topic that is up for discussion. This period is an indication for the designing and installation of space maintainers. The goal of therapy in such situations is to maintain the position of the deciduous dentition in the arch until the eruption of permanent teeth takes place and those teeth take their natural and correct positions. Depending on the method of fixation, space keepers can be fixed, cemented and mobile. These devices are divided by the way they function into active (enable the increase of space by their action) and passive. Space maintainers are a bit neglected, and they represent a very important clinical treatment whose use can bring a lot of benefits, both prophylactic and therapeutic. The development of biomaterials and digitalization in dental practice can direct us to modify and improve this therapeutic method.
