The definition of "Oral Health and Relationship between Oral Health and Quality of Life" was recently reviewed by Patrick Hescot, president of the FDI World Dental Federation, in 2017, addressing oral health as a determinant of general and psychophysics health on quality of life. Since oral health includes a series of skills (speaking, smiling, tasting, chewing, swallowing and facial expressions), conditions such as oral pain, discomfort and/or diseases can affect quality of life at varying degree of severity. 1,2 As example, caries may determine excessive suffering, growth
Dental development is relatively independent from other systems maturation. Recent studies have reported changes in the timing of tooth development for contemporary children comparing to children that lived more than 30 years ago (secular trend). Detectable variations in the tempo of tooth mineralization and duration of tooth maturation between children from different geographical regions were reported. Dental age is important not only for dental specialists, but also for pediatricians (in the evaluation of growth and development of healthy children, in pediatric endocrinology, in children with different diseases or syndromes) and forensic doctors (in order to estimate the age or to identify the child). The aim of our study was to investigate the regional characteristics of dental maturation in actual Romanian children. We conducted a cross-sectional study on a final sample of 441 radiographs of patients aged between 5.5 and 14.5 years (218 girls and 223 boys). The dental panoramic radiographs were scored by two examiners and intra-and inter-examiner calibration was made. We used a dedicated software for easy scoring, automatic dental age determination and as a database. On average, the Romanian girls showed an overestimation of 0.36 years, meaning 132 days, p=0.129, α = 0.05 and boys an underestimation of 0.04 years, meaning 15 days, p = 0.852, α = 0.05. New tables were developed in order to convert dental maturity calculated according to Demirjian method into dental age of contemporary Romanian children.
Plastic materials are widely used today in Paedodontics and Orthodontics for manufacturing preventive and therapeutic devices. Since these are worn for long times in the oral cavity biofilm forms on the smooth acrylic surfaces of those appliances. The biofilm must be removed not to destroy the oral microbiology. The aim of this study was to research the possibility of removing the microbial biofilm and disinfecting retainers using the photodynamic effect of toluidine blue O, Fotosan System (CMS Dental, Copenhagen, Denmark) in comparison to two products available on the market Corega Denture Cleanser Tablets (GlaxoSmithKline) and the Retainer Brite� Cleaning Tablets (DENTSPLY International Raintree Essix, FL, USA). The plastic material used in this experiment was the cold-cure acrylic Palapress� vario (Heraeus-Kulzer GmbH, Hanau, Germany). Images of the biofilm formed by Streptococcus pyogenes were obtained using a confocal laser scanning m icroscope. The images were analyzed using Comstat 2 software. The results showed that all the three investigated methods had a disinfectant effect. Corega Denture Cleanser Tablets reduced most of the biofilm formed on the plastic substrate.
Background: Dental age assessment is very useful in the pediatric dentist's and orthodontist's everyday practice. The eventual lack of correlation between dental age, skeletal maturation and chronological age can infl uence treatment procedures regarding mostly their application time. The aim of our study was to investigate the relationship between dental age based on the calcifi cation stages of the fi rst lower premolar (PM1i) and skeletal maturity stages using cervical vertebrae (C2, C3, C4) among Romanian individuals and to determine the clinical value of the fi rst premolar as a growth evaluation index. Material and methods: In a sample of 30 patients (13 males, 17 females) ranging in age from 9 to 15 years (mean age 11.2 years) we examined the orthopantomography radiographs (OPT) and lateral cephalometric radiographs of each case. Results: The biological development of girls is about 1.5 years more advanced than in boys. When the Demirjian Index was at stage F, then CVS was at stage 3.4, which means that in developmental stage "F" (according to Demirjian index) premolars are indicators of the optimal time for orthodontic treatment. We found a signifi cant correlation (R = 0.871, p <0.001) between CVM and Demirjian's index. Conclusions:The correlation shown in this study will allow clinicians to use mandibular fi rst premolar as an adjunctive tool to assess adolescent growth spurt, combined with the evaluation of the cervical vertebrae. The results also show the usefulness of the assessment of the development of dental status as a simple diagnostic test to determine the biological age of the population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
