The influence of sedation and general anesthesia to patients' psycho-emotional status undergoing wisdom teeth extraction: a pilot clinical trial

Background: Patients usually face negative psycho-emotional status during teeth extraction, therefore sedation and general anesthesia are often selected for wisdom teeth extractions. The aim of this study is to evaluate the difference between sedation and general anesthesia patients' psycho-emotional status and pain, using Universal Scale in Oral Surgery for Psycho-Emotional Rating (USOS), Visual Analogue Scale (VAS) and Modified Corah's Dental Anxiety scale (MDAS). Methods: In the period of 10/21/2019–01/31/2020 a prospective control study was held of adult patients for extraction of four wisdom teeth with sedation or general anesthesia. Patients were evaluated using self-reported questionnaires and physician questionnaire. Results: In total 53 patients were included in study: 43 in the sedation group (SG) and 10 in the general anesthesia group (GAG). Patients' psycho-emotional status was significantly (p < 0.05) more negative in both groups at the day of surgery than before it, but the difference of fear was higher in GAG (p < 0.05). Immediately after surgery GAG (3.80) felt statistically significantly (p < 0.05) more pain than SG (2.60). Conclusion: Sum of USOS, MDAS, dental fear data scores, pulse measurements directly correlated with time, i.e. statistics increased as surgery approached. The pain sensation differences were found only in the assessment immediately after surgery

Surface properties and osteoblastic cytocompatibility of two blasted and acid-etched titanium implant systems with distinct microtopography

OBJECTIVES: The aim of this study is to compare two commercially available screw-type sandblasted and acid-etched (SLA) Ti implant systems from Eckermann Laboratorium S.L., with similar geometry and distinct microtopography, regarding surface properties and osteoblastic cytocompatibility. MATERIAL AND METHODS: Implant I (referred as a conventional SLA system) and Implant II (a system patented as Eckcyte(®)) were characterized for macro and microtopograpphy, surface roughness and chemical composition. For the cytocompatibility studies, human bone marrow osteoblastic cells were seeded over the implants' surface, and the cell response was assessed for cell adhesion and proliferation, alkaline phosphatase (ALP) activity and matrix mineralization. RESULTS: Implant I presented a rough surface with irregularly shaped and sized cavities among flatter-appearing areas, whereas Implant II exhibited a homogeneous rough microporous surface. Compared to Implant I, Implant II presented higher Ra values (0.8 [SD 0.008] μm and 1.21 [SD 0.15] μm, respectively, P < 0.05) and also increased values of Rz, Rt and Rsm, a more negative value of Rsk, and similar RKu values. XPS showed the expected presence of Ti, O, C and N; Al, Si, F, P and Ca were detected in low concentrations. Implant II exhibited significantly lower Al levels. Both implants supported the adhesion, proliferation and differentiation of osteoblastic cells. Implant II showed a thicker fibrilar cell layer and an earlier onset and more abundant matrix mineralization. CONCLUSIONS: The homogeneous rough and microporous surface of Implant II is most probably a main contributor for its improved cell response

Scientific Publications in Dentistry in Lithuania, Latvia, and Estonia Between 1996 and 2018: A Bibliometric Analysis

This study aimed to determine the number and quality of scientific publications in dentistry from the Baltic countries of Lithuania, Latvia, and Estonia between 1996 and 2018 using bibliometric analysis. Web of Science and Scopus were searched to identify scientific publications in dentistry between 1996 and 2018 by authors from centers in Lithuania, Latvia, and Estonia. The annual number of scientific publications, citation rate, and h-index for each publication, and trends in international co-authorship were investigated by country and institution. There were 651 scientific publications in dentistry between 1996 and 2018, by authors from Lithuania (280 publications), Latvia (210 publications), and Estonia (161 publications). Publications from Estonia were ranked highest in qualitative terms (citation rate and h-index), followed by Lithuania, and Latvia. Of 28 authors with at least ten publications, 54% were Lithuanian (15 authors), 25% were Estonian (7 authors), and 21% were Latvian (6 authors). Estonian authors collaborated mainly with Finland (27 publications), Latvian authors with the USA (16 publications), and Lithuanian authors with Canada (26 publications). Most publications came from the academic institutions of the Lithuanian University of Health Sciences (136 publications), the University of Tartu (109 publications), Vilnius University (101 publications), and Riga Stradins University (28 publications). During the past 22 years, authors from Lithuania had the most publications in the field of dentistry, and authors from Estonia had the most cited publications. Authors mainly published in native journals and collaborated with authors in Scandinavia and North America

Slow Resorption of Anorganic Bovine Bone by Osteoclasts in Maxillary Sinus Augmentation

Purpose: Different biomaterials have been suggested for guided bone regeneration (GBR). These might show the ideal properties to let a new bone formation in the grafted area. Among these ideal features, it is essential their controlled resorption in order to be replaced for new vital bone. Bovine bone has been used widely as a good biomaterial for GBR, however there is still an interesting controversy about its resorbable capacity. In this sense, the objective of this study was to examine the behavior of anorganic bovine bone (ABB) in long‐term maxillary sinus graft healing and study its relationship with morphological and morphometrical variables. Materials and Methods: Seventeen maxillary sinus augmentation procedures were performed in patients. Bone cores were obtained from implant receptor sites at 6 months, 3 years, and 7 years of implant placement for histological, morphometric, and immunohistochemical (tartrate resistant acid phosphatase [TRAP]/cathepsin K/CD68) studies. Results: The percentages of bone, ABB particles, connective tissue, osteocytes, and osteoblasts in maxillary sinus grafts were similar at 6 months, 3 years, and 7 years. A progressive and significant decrease was detected in osteoclasts ( p  = .05, Kruskal‐Wallis test), TRAP and cathepsin K expression ( p  = .014 and p  = .021, respectively), and osteoid lines ( p  = .038). Conclusion: According to these data, a decrease in osteoclasts over time may, partially, explain the ABB persistence observed in core biopsies. Further studies with more cases and different graft maturation times are required to elucidate the resorption rates and cell events underlying these phenomena.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/101852/1/cid445.pd

PREFACE. The 1st Baltic Osseointegration Academy and Lihuanian University of Health Sciences Consensus Conference 9 - 10 September 2016, Kaunas, Lithuania

Baltic Ossoeintegration Academy (BOA) together with the Lithuanian University of Health Sciences (LSMU) and Universities from Europe and USA organized their first Consensus Conference (CC) devoted to the topic of peri-implantitis. BOA - LSMU consensus development group (CDG) was seeking to review the dental literature on a topical area in implantology and to produce high-quality, unbiased evidence-based guidelines and consensus statement (CS). CDG as the responsible body formulated the task of developing CS devoted to the topic of peri-implantitis to Gintaras Juodzbalys (Lithuania). CS Panel members were invited by the chairman. They are representatives of Universities, experts in a field and made every effort to produce nonbiased, independent, evidence-based clinical practice guidelines. Panel members had no conflicts of interest and signed a Panel Member Agreement (PMA). Working groups were established and following clinically relevant topics suitable for consensus discussion were identified: Peri-Implantitis Aetiology, Risk Factors and Pathology (group leader: Claudio Stacchi) [1]. Peri-Implantitis Diagnostics and Decision Tree (group leader: Tolga Fikret Tözüm) [2]. Peri-Implantitis Treatment (group leader: Fernando Suárez-López del Amo) [3]
