Dental autotransplantation is a surgical procedure where tooth or dental germ
is transffered from one position to another, within the same person. This
way an edentulous area after extraction can be ...successfully restored without
the need of other more invasive approaches. This procedure is recommended in
young individuals who have lost permanent molars due to caries complications
and have an impacted third molar as a potential donor tooth. The aim of this
report is to present a successful transplantation of wisdom tooth into the
alveolus of the first mandibular molar in a case of a young individual.
Introduction/Objective. Success of guided bone regeneration depends on the size and morphology of defect, characteristics of barrier membranes and adequate angiogenesis. The aim of the study was to ...reveal impact of three different collagen membranes on angiogenesis and bone production in critical-size defects. Methods. Defects were created in rabbit calvarias, filled with bovine bone graft and randomly covered with one of three investigated collagen membranes (Biogide ? BG, Heart ? PC, Mucograft ? MG) or left without a membrane for the control group (C). After two and four weeks of healing, a total of 10 animals were sacrificed for histological and histomorphometric analysis of angiogenesis, bone regeneration, and inflammatory response. Results. In the early healing phase, the highest values of trabecular thickness and trabecular area were recorded with PC and BG membranes, respectively. After four weeks, significantly improved bone healing was noted in the MG group, as well as significantly pronounced inflammation. Initially, vessel density was significantly higher in the C group compared to all three membranes. After four weeks, significantly better results were observed in the MG compared to the other groups, BG compared to the rest of groups, and between PC and C groups. Conclusion. The use of collagen membranes significantly affects angiogenesis, reducing it in the early and enhancing it at the later healing phase. All three tested membranes in combination with bone graft significantly improved the amount of regenerated bone. Among the investigated groups, MG favored more pronounced angiogenic, osteogenic, and inflammatory response in the observation period of four weeks.
Purposes
The primary aim of the study was to investigate a 1‐year success rate of early‐loaded bone level implants with a chemically modified sand‐blasted, large grit, acid‐etched surface (SLActive®, ...Institut Straumann AG, Basel, Switzerland) in the posterior maxilla. Secondary objectives included stability of these implants and peri‐implant bone level.
Materials and Methods
Bone level® implants (Institut Straumann AG) inserted into premolar and/or molar maxillary sites were loaded after 6 weeks of healing. The implants were monitored for 1 year using the following outcome measures: implant success, primary and secondary stability, and peri‐implant bone level.
Results
Out of 37 implants placed in 13 patients, 36 reached sufficient stability and were early loaded, whereas one underwent a delayed loading protocol. One‐year success rate of early‐loaded implants was 100%. Implant stability at baseline was 71.7 ± 5. 6 to be steadily increased thereafter up to 1 year (80.3 ± 3.3), except at 2 weeks when a nonsignificant decrease was noticed (71.9 ± 3.9). Continuous and significant bone loss was observed, reaching 0.4 ± 0.1 mm in the first postoperative year.
Conclusion
Bone level implants with the SLActive surface placed into low‐density bone and loaded after 6 weeks of healing can predictably achieve and maintain a successful tissue integration.
Surgical treatment of odontogenic cysts in childhood could be accompanied by injury of important anatomical structures. Even though enucleation is considered to be preferable treatment of odontogenic ...cysts, the specificities of pediatric age favor more conservative surgical approach. The aim of this study was to assess the effectiveness of decompression as the uttermost treatment of odontogenic cysts in the pediatric age.
This retrospective study included 22 patients, 7-16 years old, with a single jaw cystic lesion. The majority of these lesions were dentigerous cyst (14), and the rest belonged to keratocystic odontogenic tumor (KCOT) (8). All lesions were primarily treated with decompression; it was a final treatment (one-stage procedure) in 13 dentigerous cysts, and it was followed by enucleation (two-stage procedure) in one dentigerous cyst and all the KCOT.
A total of 13 (59.1%) dentigerous cysts were treated successfully only with decompression as one stage procedure, while the other 9 (40.9%) cysts required enucleation (1 dentigerous and 8 KCOT), after decompression (p ≤ 0.001).
Related to non-aggressive lesions, more conservative treatment approach, such as decompression as one-stage procedure, should be considered. On the other hand, KCOTs in children require a two-stage procedure for a successful treatment outcome.

Juvenile paradental cysts (JPC) are rare cystic lesions that usually develop
on buccal, distal, or mesial side of first, and rarely second permanent
mandibular molars. They occur during tooth ...eruption, in children aged 6 to 12
years, and belong to the group of inflammatory paradental cysts. Clinical
symptomatology is scarce and often manifested as appearance of painless
swelling on the buccal side of the offending tooth. Different therapeutic
procedures could be used: enucleation, enucleation with tooth extraction or
marsupialization. This study presents the marsupialization procedure of
bilateral JPC attached to the first permanent lower molars in seven year old
girl.
Juvenilne paradentalne ciste (JPC) su retke cisticne lezije koje se uglavnom
razvijaju na bukalnoj, distalnoj ili mezijalnoj strani prvog, a znatno redje
drugog stalnog molara u donjoj vilici. Nastaju tokom njihovog nicanja kod
dece uzrasta 6-12 godina i pripadaju grupi inflamatornih paradentalnih cista.
Klinickih simptoma je vrlo malo, a oboljenje se najcesce ispoljava u vidu
bezbolnog otoka sa bukalne strane zahvacenih zuba. Terapijski pristup
podrazumeva enukleaciju, enukleaciju sa vadjenjem zuba ili marsupijalizaciju.
Prikazujemo slucaj marsupijalizacije bilateralne JPC prvih stalnih donjih
molara kod sedmogodisnje devojcice.
Clinical presentation of acute odontogenic infections may vary, while adequate evaluation of its severity is of great importance for determination of appropriate and effective therapy.
The aim of the ...present study was to monitor changes of C-reactive protein (CRP) levels, to correlate its values with symptoms of different acute odontogenic infections (AOI), and to monitor the effectiveness of the applied therapy.
Fifty-four patients with AOI were included in the study. Eighteen patients with good drainage and normal body temperature were treated only by surgical incision without using antibiotics. Twenty-two patients with poor drainage after incision and normal body temperature were treated by surgical incision and antibiotics. Fourteen patients with elevated body temperature were treated by incision and antibiotics, irrespective of the quality of the drainage. CRP levels were measured on admission, on the 3rd and 7th day after therapy initiation.
On admission CRP levels were higher in AOI with elevated body temperature compared to poorly and well-drained AOI. There were no differences in CRP levels between well and poorly drained AOI on admission. On the 3rd day, a decline in the CRP levels was evident in all three groups of patients, and there was no difference among the groups. On the 7th day, the CRP levels normalized in all groups.
CRP levels correlate well with the severity and resolution of AOI and could be used as a reliable parameter in monitoring the effectiveness of AOI therapy.
Introduction. The stimulating effect of low-power laser on the process of wound healing is characterized by proliferation of fibroblasts, collagen production, and enhanced enzyme activity. The aim of ...this study was to evaluate the possible enhancing effect of low-power laser on the rate of the healing artificially created osseous defects in rats. Material and methods. Ten albino Wister rats were involved in this experimental study. Round defects (3 mm wide 2 mm deep) were made in each rat on both femurs. The right side was experimental while the left side was control. Osseous defects on the experimental side were daily treated with Galium, Aluminium, Arsenid (GaAlAs) low-power laser (Medicolaser 637, Technoline, Belgrade, Serbia), at the energy output of 4 J/cm2, with constant power density of 50 mW, and a wave length 637 nm (visible red light) per defect during seven days. Defects on the control side healed spontaneously. The effects of laser were evaluated two and three weeks postoperatively. Results. Histological analysis showed the powerful osteoblastic activity on the bone defects of the experimental side two weeks after surgery. On the control side, a new bone formation was noticed at the periphery of the bone defects but fibroblastic tissue with no signs of new bone was presented in the central areas. Three weeks after surgery, on the experimental side, bone defects were completely filled with spongious, lamellar bone while non-treated bone defects were characterized by mature lamellar bone at the peripheral areas and immature bone at the central areas. Conclusion. The results showed that the use of low-power laser could have a significant influence on the speed of curing bone defects in rats.

Uvod. Laseri male snage uticu na proces zarastanja rana, koji odlikuju proliferacija fibroblasta, brze stvaranje kolagena i pojacana aktivnost enzima. Cilj ovog rada je bio da se proceni efekat lasera male snage na zarastanje vestacki izazvanih ostecenja kosti laboratorijskih pacova. Materijali i metode rada. U istrazivanju je korisceno 10 albino vister pacova. Kod svakog od njih su na obe butne kosti nacinjena okrugla ostecenja (3 mm siroka i 2 mm duboka), s tim da je desna bila eksperimentalna strana, a leva kontrolna. Eksperimentalne strane su svakodnevno tretirane galijum-aluminijum-arsenid (GaAIAs) mekim laserom (Medicolaser 637, Technoline, Belgrade, Serbia) sa izlaznom snagom od 50 mW, koristeci 4J/cm2 po ostecenju tokom sedam dana. Kontrolne strane su ostavljene da spontano zarastu. Efekti ozracenosti laserom su procenjivani dve i tri nedelje posle operacije. Rezultati. Dve nedelje nakon operacije histoloskom analizom ostecenja kosti eksperimentalne strane uocena je snazna aktivnost osteoblasta. U istovremena kontrolnoj strani zapazeni su novoformirani kostani izdanci na periferiji ostecenja kosti, odnosno fibroblasticno tkivo bez znakova stvaranja nove kosti u centralnom delu ostecenja. Tri nedelje nakon operacije eksperimentalna ostecenja kosti su potpuno bila ispunjena sundjerastom lamelarnom kosti, dok su netretirana ostecenja kosti odlikovale zrela lamelama kost na perifernim delovima i nezrela kost u centralnim delovima. Zakljucak. Dobijeni nalazi pokazuju da koriscenje lasera male snage moze znacajno uticati na brzinu zarastanja ostecene kosti kod laboratorijskih zivotinja.
Decoronation is a surgical procedure based on idea of sectioning tooth crown and maintaining the root in situ with intention to preclude occurrence of severe deformities of bone and soft tissue which ...may aggravate later rehabilitation of patient. The aim of this report is to present the use of decoronation in a young adult patient as a solution in order to preserve sufficient amount of bone for delayed implant placement and decrease volume of grafting material to a minimum. Obtained results showed this procedure may greatly improve anatomical conditions for implant placement while reducing invasiveness and required financial means.
The author analyses in the paper the sociocultural aspects of consumption, consumer culture and society. With regard to the fact that values in the field of consumption are pouring over into other ...areas of social activity, it can be concluded that modern society in totum is a consumer culture, and not only in its specific consumption activities. One of the main hypotheses of the paper is that the problem of interpreting the consumer revolution, and thus the emergence of contemporary consumer culture and society, is connected to the key question in sociology – the question of the fate of the Protestant ethic. What remains after abandoning the Protestant ethic is only hedonism, which has become the cultural excuse for capitalism. Consumer culture is related to modernity as a whole as well as the main values, practices and institutions that define Western modernity such as choice, individualism and first and foremost market relations. The market is the main determinant of consumer culture. On the other hand, consumption is manifested as the privileged place of the autonomy of meaning, subjectivity, privacy and freedom. For critics of consumer culture it can be observed not as an individual liberation but an anomy, not as social
progress but pathology. Further analysed are some contemporary approaches to consumption, consumer culture and society, whereby the fact emphasised is that the world of commodities and its principles of structuration are crucial in understanding contemporary society.
