Effectiveness of a new method of disinfecting the root canal, using Er, Cr:YSGG laser to kill Enterococcus faecalis in an infected tooth model.
2013
Some lasers have demonstrated to provide effective disinfection when used as adjunctive device to the conventional treatment. The aim of this in vitro study was to determine the effectiveness of the erbium, chromium:yttrium scandium gallium garnet (Er, Cr:YSGG) laser by measuring its bactericidal effect inside the root canal experimentally colonized with Enterococcus faecalis. The laser was tested at different irradiation times (30 and 60 s) and energy of impulses (75 and 25 mJ). A total of 52 single-rooted extracted human teeth were endodontically prepared with rotary instrumentation. All were sterilized and inoculated with a suspension of E. faecalis (105 bacteria/ml). The teeth were rand…

Trends over Time in Dental Caries status in Urban and Rural Thai Children.
2017
Background Historically, the prevalence of dental caries was higher in urban areas than rural areas of Thailand. This study aim to examine the time trends in caries status in children in Thailand. Material and Methods Linear regression was used to examine trend of dental caries prevalence and mean number of teeth with caries, filled and missing due to caries (dmft/DMFT) in urban and rural, of 3-, 5-6 and 12-year olds from seven Thailand National Oral Health Surveys conducted approximately every 5 years from 1977 to 2012. Results There were declines in the caries prevalence and mean dmft/DMFT in every age group. Significant results were observed in the mean dmft of 3 year-olds and the mean D…
A tooth whitening and chemical abrasive protocol for the treatment of developmental enamel defects
2018
Abstract This clinical report describes a chemical abrasive protocol and whitening techniques to quantify modifications to the color and volume produced when eliminating white spots associated with developmental defects in enamel. Chemical (oxidative-erosive) abrasive treatment (whitening + 6.6% hydrochloric acid) resolves white spots up to a depth of 0.2 mm. At greater depths, infiltration with 16% hydrochloric acid followed by composite resin infiltration is recommended.
Risk Factors Associated with Carious Lesions in Permanent First Molars in Children: A Seven-Year Retrospective Cohort Study
2020
The aim of this study was to evaluate the risk factors associated with the occurrence of caries in permanent teeth (PT) and in the permanent first molar (PFM) seven years after their eruption. Children born in 2005 who were enrolled in a Community Dental Program were included. A total of 278 children were enrolled. Evaluated risk factors were parental caries experience, educational level of the mother, routine medications, systemic diseases, dietary habits, toothbrushing frequency, existence of molar incisor hypomineralization (MIH) in the PT, and caries in the temporary teeth (TT). Associations between independent variables and the DMF-T (decayed, missing, and filled teeth in PT) and DMF-M…
Estudio "in vivo" sobre diferentes métodos para el diagnóstico de caries de fosas y fisuras
2014
En las ciencias médicas se va imponiendo el paradigma de que un diagnóstico precoz de las enfermedades lleva asociado un tratamiento más eficaz de las mismas. La Odontología no escapa a esa idea. No existe unanimidad en la literatura a la hora de afirmar cuál de los métodos o sistemas diagnósticos es el ideal para diagnosticar lesiones incipientes de caries. El estudio cuenta con la aprobación del Comité de Ética de Investigacaión en Humanos de la Universitat de València. La muestra consta de 302 dientes procedentes de 152 individuos con una edad media de 39 años. Se trata de molares y premolares que previamente habían sido diagnosticados para obturación con los métodos tradicionales o iban…
Evaluation of caries risk in a young adult population
2007
Introduction: Various caries risk prediction models have been developed in recent years. Cariogram®, a software program that evaluates an individual’s caries risk profile and illustrates it in graphic form, appears to classify patients more correctly than other risk prediction methods. Objectives: The objective of this study was to determine the caries risk of a population by means of the Cariogram® software and examine the relationships between the different variables used by the Cariogram® and the risk of caries determined by this program. Materials and Methods: Data were collected from a sample of 48 young individuals by clinical and radiological examination, saliva sampling and a dietar…
Oral-Health-Related Quality of Life and Cosleeping: The Role of Nocturnal Breastfeeding
2021
The purpose of this paper is to analyse the association between cosleeping and the number of breastfeeding sessions in infants, OHRQoL of the child and the family, and the DMFT Child’s index. The sample comprised 273 children (2–4 years old). In addition to the clinical examination of the child to assess the DMFT Index, the mother was requested to complete a questionnaire to collect data about the breastfeeding practice, diet, dental hygiene, dental check-ups, quality of the child’s oral life, and family impact (ECOHIS Scale). The children’s OHRQoL is positively correlated with number of night-time breastfeeding sessions at 12 months (r2 = 0.40 **), DMFT index (r2 = 0.60 **), impact family …
The effect of social geographic factors on the untreated tooth decay among head start children
2017
Background: Disparities among untreated dental caries exist for children from low-income families in the United States. Understanding of the mechanism of the disparities is required to reduce it and social geographic factors are one of the important influences. Although the effect of fluoridated water has been well reported, studies of other sociogeograpic factors, such as the density of available dentists, are still very limited. The objective of this study is to explore the effect of sociogeographic factors on the number of primary teeth with untreated dental caries among children from low-income families who are enrolled in Head Start programs throughout Northeast Ohio of the United Stat…
Topical Fluoride for Preventing Dental Caries in Children and Adolescents
2012
The use of topically applied fluoride has been widely researched as a means to reduce the risk of dental caries in conjunction with other treatment modalities (mechanical oral hygiene, dietary control, antimicrobial intervention, pit and fissure sealants). There is overwhelming evidence that reports not only the significance and importance of the use of fluoride as a caries-preventive agent, but also how safe fluoride application is when used appropriately, particularly in higher risk individuals and populations. This paper reviews the caries-protective benefits of topical fluoride application in children and adolescents, with an emphasis on the clinical efficacy and safety of the vehicles …
