The purpose of this study was to objectively evaluate the stability of dental implants by use of resonance frequency analysis (RFA). In this study, 60 Nobel Replace Tapered Groovy implants were placed in the premolar region of the maxilla in 60 patients. Thirty implants were placed immediately after tooth extraction and 30 implants were placed in healed bone sites.

In recent years, the delivery of osteoinductive factors such as bone morphogenic proteins (BMPs) has become an alternative approach to traditional bone grafting due to their capacity to produce bone healing and new bone formation. BMP-2 has proved to possess the highest osteoinductive potential among BMPs. The case reported the clinical use of recombinant human BMP-2 for bilateral vertical alveolar ridge augmentation.

Renaming of the Odontogenic Keratocyst as the Keratocystic Odontogenic Tumor by the World Health Organization (WHO) is based on the aggressive nature of this lesion. Satellite cysts founded in the walls of the original cysts may give rise to a new lesion formation. The aim of this retrospecitve study was to identify the existence of specific features according incidence of satellite cysts and the pallisading of the basal layer of the epithelium and to establish their mutual correlation.

Purpose: High-energy lasers have been proposed as an alternative to the conventional surgical drill in oral and maxillofacial surgery. The aims of this study were to compare thermal changes of the bone surface, procedure time, and volume of the removed bone after drilling with an erbium (Er):yttrium-aluminum-garnet (YAG) laser versus a low-speed surgical drill. The bone sections were observed under light microscopy and examined histologically.

Objective: The aim of this study was to evaluate the effect of Bluephase light emitting diode (LED) light on cell viability, colony-forming ability and proliferation in V79 cell culture and to determine how much the temperature of the nutrient medium rose.

Methods: The investigation included a low (L), soft start (S) and high (H) illumination mode for 20, 40 and 80 seconds. The viability was determined by the trypan blue exclusion test, colony-forming ability by counting colonies 7 days after exposure and cell proliferation by the cell counts on 5 post-exposure days.

Although it is still not clear whether elevated serum triglycerides are directly atherogenic or not, the results of many studies indicate that they are undoubtedly an important risk factor/biomarker for coronary heart disease (CHD). Therefore, targeting hypertriglyceridaemia should be beneficial for subjects at high risk for CHD. Elevated triglycerides are often accompanied with low HDL cholesterol, particularly in high risk patients with diabetes type 2 and/or metabolic syndrome.

Although immediate implantation has not been previously recommended in infected sites, it is now becoming a procedure of choice in modern implant dentistry. We report a case of a 65-year-old male patient, who required multiple tooth extractions in the lower jaw and fabrication of a new overdenture in the lower jaw and a complete denture in the upper jaw. Immediate implantation in infected tooth sockets followed extraction.

The clinical picture of classical homocystinuria is diverse. This is the first report of an adult homocystinuric patient with non-traumatic spontaneous small bowel perforation. A 47-year old man presented with abdominal rebound tenderness, hypotension and tachycardia, anemia, and elevated markers of inflammation.

It has been known for quite a long time that the concentration of HDL-cholesterol correlates inversely with cardiovascular disease (CVD) risk and that low HDL-cholesterol is an independent CVD risk factor. This review aims to highlight evidence on several topics concerning the role of HDL particles and the importance of HDL-cholesterol. The main antiatherogenic functions of HDL particles are presented in details--reverse cholesterol transport, but also their anti-oxidant, anti-inflammatory, anti-thrombotic and anti-apoptotic properties as well as endothelial stabilizing and repair properties.

The aim of this study was to obtain the 3-D qualitative and quantitative nanoscale data of the surface topography and surface roughness of glazed and unglazed feldspathic ceramics. Twelve samples composed of Ni-Cr alloy (Wiron 99, Bego Germany) and feldspathic ceramics (IPS Classic, Ivoclar-Vivadent, Schaan, Liechtenstein) were prepared, and divided into two groups, dependent of the surface final finishing; 6 unglazed and 6 glazed samples. The surface of the samples was recorded and analysed by atomic force microscopy (AFM, Veeco Instruments, Santa Barbara, CA, U.

The purpose of this paper was to determine the prevalence and impact of various etiological factors on marginal ridge fractures of teeth with amalgam fillings. 50 subjects participated in this research, 172 teeth restored with amalgam were examined out of which 28 premolars and 144 molars of both jaws. Data used in the research was obtained by nonaggressive exploration of oral cavity and by checking dental charts and radiographic charts of patients.

This study was designed to assess the impact of the surgical removal of a mandibular third molar on health-related quality of life (HRQoL) in the postoperative period. Data was obtained from 101 patients who had undergone 105 surgical procedures. Only one mandibular third molar was removed per visit.

The purpose of this study was to research the possible influence of difference in construction of mechanical joint in arcon and nonarcon articulators, upon the adjustment of condylar inclination by intraoral protrusive record. The determination of condylar inclination by protrusive record in two types of articulators was performed on 30 examinees, and the adjustment of condylar inclination in each articulator was done for left and right joint. In arcon articulator the measured values for condylar inclination were higher and the mean difference for right joint was 7.

The aim of this study was to evaluate microleakage along resin restoration in cavities prepared with an erbium:yttrium-aluminium-garnet (Er:YAG) laser, with and without acid etching, and to compare it with that in diamond-drilled cavities. Thirty intact molars were divided into three equal groups. In the teeth in group I, class V cavities were prepared with a diamond drill.

Flapless technique is a surgical approach of implant placement without raising a mucoperiosteal flap. Such approach has many advantages: shorter surgical treatment, minimal bleeding, postoperative discomfort for the patient is reduced; possibility of immediate loading of the inserted implant, faster procedure of implant placement and by that less time is needed for the complete implant-prosthetic restoration. Purpose of this pilot study was radiographic assessment of flapless technique and determination of its clinical values in comparison with two-stage dental implant technique through computerized densitometric analysis.

Human paraoxonase (PON1) is a serum high-density lipoprotein-associated phosphotriesterase. High-density lipoprotein (HDL) plays the role of a carrier and the site of action of this enzyme. According to a majority of authors, PON1 acts as an antioxidant, preventing low-density lipoprotein (LDL) peroxidation.

Healing of bone defects is the most frequent cause of failure in surgical treatments of an odontogenic ostitic processes. The aim of this study was to determine successfulness in healing of bone defects after implantation of alloplastic co-polymer-polyglycol bone implant. A group of 45 cases with periradicular ostitic processes were examined.
