INTRODUCTION Previous studies have shown that populations differ with respect to interarch tooth-size relationships, and differences in tooth sizes are not systematic. The aims of this study were to determine the Bolton ratios in Spanish subjects. METHODS We used a digital method and measured the casts to the nearest 0.05 mm. The sample consisted of 100(More)
The eruption cyst is a lesion associated with an erupting tooth. It appears as a transparent, bluish, blue or blue-black swelling of the alveolar mucosa, over a temporal or permanent tooth in eruption. The analysis of the thirty-six eruption cysts cases studied, corresponding to twenty-seven patients, revealed that their most frequent location is in the(More)
The Bolton Index is one of the most useful calculations for precise orthodontic diagnosis as it shows if there is a correct ratio between dental proportions. However, at times, this calculation is not applied because it is a long and time-consuming procedure compared with digital methods. A new digital method for measuring tooth sizes and for calculating(More)
Digital technology is becoming day by day a more important procedure in most of the clinic activities and, thus, orthodontists are increasingly adding digital technology to their orthodontics records. In this article we want to outline the advantages and disadvantages of the use of digital photography, digital radiography as well as one of the latest(More)
INTRODUCTION The aim of this study was to evaluate in vivo the effect of saliva contamination at different stages of the bonding procedure on the bond failure rate and the adhesive remaining on teeth after debonding brackets bonded with a hydrophilic self-etching primer (Transbond Plus self-etching primer [TSEP], 3M Unitek, Monrovia, Calif). METHODS This(More)
To evaluate the utility of CA 15.3 in detecting breast cancer relapse before clinical evidence of metastatic disease, serial determinations of CA 15.3 serum levels were made in 444 disease-free patients after surgery, during 36 months of follow-up. The results were compared with carcinoembryonic antigen (CEA) and tissue polypeptide antigen (TPA). The study(More)
The specificity and sensitivity of a tumor marker (TM) are important in establishing its potential clinical utility for a specific type of neoplasm. CA 15.3 is a TM specific for breast cancer; it is defined by two monoclonal antibodies (DF3 and 115D8), whose specificity, in disease-free follow-up patients, and sensitivity, in patients at diagnosis of first(More)
This work presents the development of a protocol based on the dynamic laser speckle designed to monitor the reaction of cancer cells of line MEL-RC08 to the application of the drug Colcemid in two different concentrations: 0.2 and 0.4 μg/mL. The protocol was designed using the forward scattering approach with an He-Ne laser of 632.8 nm illuminating the(More)
AIM To investigate the relationship between morphology and position of double teeth, and the occurrence of other dental anomalies in the same subjects and in their siblings. SAMPLE OF CHILDREN AND METHODS: Fifty-three double teeth in a group of 50 Spanish children were included in the study. All of these children were examined clinically and had radiographs(More)
OBJECTIVES Cone Beam Computerized Tomography (CBCT) allows the possibility of modifying some of the diagnostic tools used in orthodontics, such as cephalometry. The first step must be to study the characteristics of these devices in terms of accuracy and reliability of the most commonly used landmarks. The aims were 1- To assess intra and inter-observer(More)
