Influence of immigration and other factors on caries in 12- and 15-yr-old children.
2007
In recent years the Valencia region has undergone mass immigration, mainly of people from eastern Europe, North Africa, and Latin America. The objective of this study was to assess the effect of immigration on caries prevalence and experience in 12- and 15-yr-old children in the Valencia region, and to relate this to other socio-economic and oral hygiene-related variables. The data were obtained from the epidemiological study of oral health carried out in the Valencia Region in 2004. The study group comprised 478, 12-yr-old children and 401, 15-yr-old children. Immigration status, age, toothbrushing frequency, and intake of cariogenic foods between meals showed significant association in a …
Prevalence of root caries among elders living in residential homes of Bengaluru city, India
2015
Background: Among the various oral ailments which have been observed in elderly, root caries is a significant one. Tooth loss is chief oral health-related negative variable to the quality of life in elderly and root caries is the major cause of tooth loss in them. It has been reported about a third of older population bears most of the root caries burden, so the present study aimed to assess the prevalence of root caries among older individuals residing in residential homes of Bengaluru city India. Material and Methods: Elderly individuals aged 60 and above, residing in residential homes of Bangalore city, were included in the study. The study participants filled a questionnaire regarding t…
Probiotics and oral health
2012
Probiotics are living microorganisms (e.g., bacteria) that are either the same as or similar to organisms found naturally in the human body and may be beneficial to health. Current researches have shown that the balance between beneficial and pathogenic bacteria is essential in order to maintain the oral health. Therefore, oral cavity has recently been suggested as a relevant target for probiotic applications. Dental caries can be seen as a microbial imbalance where the oral microbiota shift towards community dominance which produces acidogenic and acid-tolerant gram positive bacteria. Similarly, the accumulation of bacteria within the biofilm, facilitated by poor oral hygiene, predisposes …
Progressive symmetric erythro-keratosis associated with oligodontia, severe caries, disturbed hair growth and ectopic nail: a new syndrome?
2008
A 7-year-old girl had well-demarcated erythematous plaques covered with white pityriasiform scales which were symmetrically distributed and involved the extensor surfaces of the extremities as well as the abdomen, buttocks and face. Histological examination showed marked hyperkeratosis with parakeratosis, and a thickened granular cell layer, mild acanthosis and slight lymphocytic infiltration surrounding the papillary blood vessels, compatible with a diagnosis of progressive symmetrical erythrokeratodermia. Remarkably, a keratotic excrescence similar to a normal nail plate involved the tip of the nose since the age of 6 months. Moreover, occipital hairlessness, oligodontia and severe caries…
Caries Prevalence Evolution and Risk Factors among Schoolchildren and Adolescents from Valencia (Spain): Trends 1998–2018

Kariesa izplatība, kas novērtēta ar ICDAS II (starptautiskā kariesa noteikšanas un novērtēšanas sistēma), pirmsskolas vecuma bērniem Latvijā
2019
Ievads Zobu kariess ir plaši izplatīta multifaktoriāla slimība, kas ietekmē visu populāciju, tomēr pieejami maz datu par zobu kariesa prevalenci Latvijas populācijā. Šis šķērsgriezuma pētījums tika veikts 2018.gadā Rīgas apkaimē, lai novērtētu kariesa prevalenci pirmsskolas vecuma bērniem. Šī pilotpētījuma galvenie mērķi bija, pirmkārt, izpētīt kariesa prevalenci starp 2-6 gadus veciem bērniem Latvijas bērnudārzā, pielietojot ICDAS II; otrkārt, salīdzināt ICDAS II kritērijus ar DMF indeksu, lai izvērtētu kariesa prevalenci. Metodes Kopumā tika izmeklēti 176 Latvijas bērnudārza bērni vecumā no 2 līdz 6 gadiem. Zobu kariesu izvērtēja, lietojot ICDAS II kritērijus. Bērni tika iedalīti 2 gadu, …
Microradiography and confocal laser scanning microscopy applied to enamel lesions formed in vivo with and without fluoride varnish treatment
1996
The aim of the present investigation was to combine 2 techniques suitable for lesion characterization: quantitative microradiography (TMR) and confocal laser scanning microscopy (CLSM) on in vivo induced lesions with and without a fluoride varnish (Duraphat(R)) treatment. Orthodontic bands were attached to premolars to be extracted for orthodontic reasons to induce enamel caries on the buccal surfaces. In the caries development part of the study, 1 tooth of each pair received at the start 1 topical application with the fluoride varnish Duraphat(R), the contralateral tooth serving as untreated control. All teeth were extracted after 4 weeks. In the caries progression part, the premolars were…
Using ultrasound transmission velocity to analyse the mechanical properties of teeth after in vitro, in situ, and in vivo irradiation.
2000
Ultrasound transmission velocity (UTV) in isotropic material as a measure for the modulus of elasticity was correlated to mechanical properties. Changes in micromechanical properties of radiated teeth and influence of the oral cavity were to be evaluated nondestructively. UTV was measured in extracted teeth after 36 Gy and 62 Gy of in situ (enorally, with no contact to the oral cavity) and in vitro irradiation. Relative to controls, teeth subjected to 62 Gy in vivo showed higher UTV values for dentine and enamel. Sound teeth irradiated with 60 Gy in situ also showed higher UTV values for enamel, whereas dentine values were not significantly different from those of control. The mechanical pr…
Is there association between chronic kidney disease and dental caries? A case-controlled study
2018
Background The purpose of this study was to assess the association between chronic kidney diseases (CKD) and dental caries. Material and Methods 107 patients with CKD and 107 with no systemic alteration were randomly included. DMFT (decayed, missing, and filled teeth), plaque index, colony-forming units (CFU) of Streptococcus mutans and salivary composition (IgA total, IgA anti- Streptococcus mutans, calcium and urea) were evaluated. McNemar and Wilcoxon tests were used to compare test and control groups. Spearman test was used to correlate time of hemodialysis and variables studied. Associations between variables were evaluated by logistic regression analysis. Results The number of filled …
Italian Deprivation Index and Dental Caries in 12-Year-Old Children: A Multilevel Bayesian Analysis
2014
Evidence from the literature has shown that people with a lower socioeconomic status enjoy less good health than people with a higher socioeconomic status. The Italian deprivation index (DI) was used with the aim to evaluate the association between the DMFT index and risk factors for dental caries, including city population and DI. The study included 4,305 12-year-old children living in 38 cities classified by demographic size as small, midsize and large. Zero-inflated negative binomial multilevel regression models were used to assess risk factors for DMFT and to address excess of zero DMFT and overdispersion through a Bayesian approach. The difference in the average level of DMFT among chi…
