    Introduction. In dental surgery digital cameras play a major role. High quality intraoral pictures are useful in scientific and didactic activity. Aim of the study. The aim of the study was to compare the quality of intraoral photographs performed with a simple compact digital camera using lighting from the dental unit lamp and an advanced set based on a DSLR camera in patients under surgical treatment. Material and methods. The study was conducted in the Department of Dental Surgery at the Medical University of Lodz, Poland, from 24.10.2012 to 15.01.2013. The first study arm consisted of 37 adult patients undergoing dental surgical treatment. Intraoral photographs were performed in two series using different equipment sets: 1) using simple compact digital camera and lighting from the dental unit lamp, 2) using a DSLR camera with a makro lens and a ring flash. The photographs were gathered in photograms, printed in high quality and presented to the group of 10 dentists for evaluation according to 3 criteria. Results. According to our study, the quality of photographs performed with a simple compact digital camera using lighting from the dental unit lamp is worse than the quality of photographs performed with advanced set basing on a DSLR camera in all 3 criteria. Conclusion. In situations, where high quality of intraoral photographs is required, using advanced photographic set basing on DSLR camera is highly recommended

    Use of fractal analysis for bone assessment

    Get PDF
    Since Mandelbrot announced the concept of the fractal geometry, fractal analysis has been used in the description of various structures found in nature and biosignals. It has been used to interpret biological phenomena such as nervous tissue, vascular system, the electrical conductivity of the heart and EEG. In dentistry, there have been many attempts to analyze the structure of jaw bones to assess periodontal disease and osteoporosis. Many authors indicate that bone tissue has a fractal structure, and that the fractal analysis can be inexpensive and convenient screening instrument in the diagnosis of systemic diseases that cause changes in the image of bones. This article is a review of applications of fractal analysis in bone evaluation

    Introduction. The most common malformations associated with cleft lip and palate are dental abnormalities. Multifactorial etiology and the time of the formation of cleft palate and start building the dental lamina may be the cause of coexistence cleft defects and dental disorders. Aim of the study. Evaluation of the frequency and type of dental disorders in patients with complete unilateral cleft of the primary and secondary have been the subject of the research. Material and methods. The material consisted of panoramic films of 70 children (31girls, 39 boys) aged 8–11 years with a complete unilateral cleft of the primary and secondary. The radiographic evaluation are: dental status, number of teeth, and their construction. Results. In the group of 70 children were found to have abnormalities in the number and morphology of the teeth in a total of 60 patients (29 girls, 31 boys). The most commonly observed disorder was hypodontia (66.4%) found in 44 patients. Missing teeth (89.8%), were mainly found in upper jaw. In 67.7% hypodontia was on the incisors side located in the vicinity of cleft. There were also lack of upper premolars (29%) and central incisors (3.3%). Hyperdontia occurred in 9.6% and concerned maxillary lateral incisors on the cleft side. Another observed disorder was atypical tooth structure (24%) on the lateral incisors in the upper jaw. Conclusions. In patients with complete unilateral cleft palate primary and secondary, dental disorders were most frequently observed in the vicinity of cleft. The main dental disorder was hypodontia

    Dental implant system design and it’s potential impact on the establishing and sustainability of aesthetics

    Get PDF
    There is a growing appreciation of the importance of establishing and sustaining the aesthetics of implant restorations. Four of the most important factors for achieving this goal are: implant primary stability, implant surface, implantabutmentjunction geometry, and implant-abutment connection. This article reviews each of these factors as they relate to the design of the BIOMET 3i T3â„c Tapered Implant System and discusses the potential impact these factors can have on long-term aesthetics
