Evaluation of surgical-orthodontic treatments on impacted mandibular canines
2010
WOS: 000298087100012 PubMed: 21196853 Objective: The aim of the study was to evaluate patients treated for impacted mandibular canines through a combined surgical and orthodontic approach. Study Design: The cases which were made button operations of impacted mandibular canines were selected from 5100 panoramic radiographs taken from patients who made use of our oral and maxillofacial surgery services between January 1998 to April 2006. All of these selected patients were assessed radiographically. Pertinent information such as sex, age at the time of surgery, site of the unerupted tooth, space availability and any other associated pathoses were also recorded. These patients were called agai…
Gray value measurement for the evaluation of local alveolar bone density around impacted maxillary canine teeth using cone beam computed tomography
2021
Background To investigate whether any relationship between local alveolar bone density and maxillary canine impaction using gray values from cone beam computed tomography. Material and Methods The cone beam computed tomography images of 151 patients were retrospectively evaluated. Maxillary canine was defined as an impacted tooth when root formation was complete and the patient’s age older than 13 or the other side of the maxillary canine has completely erupted. Similarly, complete eruption was defined as the tooth in its expected occlusion and position. Using the cone beam computed tomography software, the region of interest which was 5 mm2 in area, was placed in the trabecular bone on cro…
Impacted maxillary canines and root resorption of adjacent teeth: a retrospective observational study
2016
Background The prevalence of impacted maxillary canine is reported to be between 1% and 3%. The lack of monitoring and the delay in the treatment of the impacted canine can cause different complications such as: displacement of adjacent teeth, loss of vitality of neighbouring teeth, shortening of the dental arch, follicular cysts, canine ankylosis, recurrent infections, recurrent pain, internal resorption of the canine and the adjacent teeth, external resorption of the canine and the adjacent teeth, combination of these factors. An appropriate diagnosis, accurate predictive analysis and early intervention are likely to prevent such undesirable effects. The objective is to evaluate, by means…
Human toxocariasis: a report of nine cases
2008
Aim: Human toxocariasis is caused by infection with the larval stage of nematode parasites of dogs and cats, Toxocara canis or Toxocara cati. These helminths are not able to complete their life cycle in undefinitive hosts and so undergo aberrant migrations in the tissues causing a wide spectrum of signs and symptoms. Eosinophilia is often severe and sometimes represents the only sign of infection, except in ocular and neurological forms. Methods: We describe the clinical features of nine children affected by toxocariasis admitted to our Infectious Diseases department from 2004 to 2006. Results: Fever and hepatomegaly were the most common clinical findings. In two cases eosinophilia was not …
Helminth parasites of the wolfCanis lupusfrom Latvia
2009
AbstractThirty-four wolves were collected between 2003 and 2008 from throughout Latvia and examined for helminths. A total of 17 helminth species were recorded: the trematodeAlaria alata(85.3%); the cestodesDiphyllobothrium latum(2.9%),Echinococcus granulosus(2.9%),Echinococcus multilocularis(5.9%),Mesocestoides lineatus(5.9%),Taenia crassiceps(8.8%),Taenia hydatigena(41.2%),Taenia (ovis) krabbei(8.8%),Taenia multiceps(47.1%),Taenia pisiformis(20.6%),Taenia polyacantha(11.8%),Taeniaspp. (8.8%); and the nematodesAncylostoma caninum(2.9%),Crenosoma vulpis(9.1%),Eucoleus aerophilus(36.4%),Pearsonema plica(41.4%),Trichinellaspp. (69.7%),Toxocara canis(5.8%), andUncinaria stenocephala(41.2%).Ala…
A new approach to assess gold nanoparticle uptake by mammalian cells: combining optical dark-field and transmission electron microscopy.
2012
Toxicological effects of nanoparticles are associated with their internalization into cells. Hence, there is a strong need for techniques revealing the interaction between particles and cells as well as quantifying the uptake at the same time. For that reason, herein optical dark-field microscopy is used in conjunction with transmission electron microscopy to investigate the uptake of gold nanoparticles into epithelial cells with respect to shape, stabilizing agent, and surface charge. The number of internalized particles is strongly dependent on the stabilizing agent, but not on the particle shape. A test of metabolic activity shows no direct correlation with the number of internalized par…
Effect of ATP Binding and Hydrolysis on Dynamics of Canine Parvovirus NS1▿ †
2010
ABSTRACT The replication protein NS1 is essential for genome replication and protein production in parvoviral infection. Many of its functions, including recognition and site-specific nicking of the viral genome, helicase activity, and transactivation of the viral capsid promoter, are dependent on ATP. An ATP-binding pocket resides in the middle of the modular NS1 protein in a superfamily 3 helicase domain. Here we have identified key ATP-binding amino acid residues in canine parvovirus (CPV) NS1 protein and mutated amino acids from the conserved A motif (K406), B motif (E444 and E445), and positively charged region (R508 and R510). All mutations prevented the formation of infectious viruse…
Incidence of impacted and supernumerary teeth-a radiographic study in a North Greek population.
2010
Objectives: The aim of the present study was to investigate the prevalence of impacted and supernumerary teeth, apart from third molars. Study design: This was a retrospective study of 1.239 panoramic radiographs taken of patients who presented to the Department of Dentoalveolar Surgery, Implantology and Radiology at the School of Dentistry of the Aristotle University of Thessaloniki, Greece between 1991 and 1999. The panoramic radiographs and dental records were reviewed in order to determine whether there were impacted or supernumerary teeth. Observations were also made on the space in dentition, corresponding to the position of each impacted tooth, the lack of space for tooth eruption, t…

Determinants of maxillary canine impaction : retrospective clinical and radiographic study
2017
Background: The aim of this study is to evaluate determinants of maxillary canine impaction taking into account both canine position related variables and the pattern of facial growth. Material and Methods: A retrospective clinical and radiographic analysis was carried out on 109 patients aged between 9 and 10 years at the time of first evaluation. At baseline, SN-GoMe angle, the interincisal angle, the canine angle a and the canine distance d were used to characterize canine location and vertical facial growth. At the end of a two years follow up period the eruption state of each canine of each patient was recorded and accordingly classified as erupted or impacted on a clinical and radiogr…
