Dental trauma in children in Budapest. A retrospective study.

Aim: Traumatic dental injuries (TDIs) are among the most serious dental public health problems in childhood. This study aimed to determine the prevalence of anterior tooth TDIs in 7- to 18-year-old children who presented for treatment over a period between January 2007 and December 2016, and to survey the effect of an increased health awareness and educational campaign about the risk of TDIs and the importance of prevention methods in decreasing their prevalence compared with data published in the years 1985-1999.

Materials And Methods: The current study was carried out on 454 children who presented for treatment at the Department of Paediatric Dentistry and Orthodontics in Budapest, Hungary.

Complex analysis of multiple single nucleotide polymorphisms as putative risk factors of tooth agenesis in the Hungarian population.

Objectives: The role was studied of multiple single nucleotide polymorphisms in tooth agenesis in the Hungarian population using a complex approach.

Methods: Eight SNPs, PAX9 -912 C/T, PAX9 -1031 A/G, MSX1 3755 A/G, FGFR1 T/C rs881301, IRF6 T/C rs764093, AXIN2-8150 A/G, AXIN2-8434 A/G and AXIN2-30224 C/T, were studied in 192 hypodontia and 17 oligodontia cases and in 260 healthy volunteers. Case-control analysis was performed to test both allelic and genotypic associations as well as associations at the level of haplotypes.

Novel possible pharmaceutical research tools: stem cells, gene delivery and their combination.

Both stem cell research and gene delivery are very promising fields of today's biomedical research. In the present review we first attempt to summarize the state of the art in stem cell research. We describe the major categories of stem cells based on cell sources: embryonic, fetal, postnatal and induced pluripotent stem cells.

Prevalence and distribution of permanent canine agenesis in dental paediatric and orthodontic patients in Hungary.

Non-syndromic permanent canine agenesis, or combined with agenesis, or developmental absence of other tooth types, has occasionally been described in the literature, but isolated forms are rarely observed. The purpose of the present retrospective radiographic study was to provide data on the prevalence and distribution of permanent canine agenesis in the Hungarian population. Dental panoramic tomograms and the medical history data of 4417, 6- to 18-year-old children (average age 12 years, male-to-female ratio 1:1), who presented for treatment at the Department of Paediatric Dentistry and Orthodontics of the Semmelweis University Budapest, Hungary, were examined.
