Dental disease and dietary isotopes of individuals from St Gertrude Church cemetery, Riga, Latvia.

2018

This research explores oral health indicators and stable carbon and nitrogen isotope data to explore diet, and differences in diet, between people buried in the four different contexts of the St Gertrude Church cemetery (15th– 17th centuries AD): the general cemetery, two mass graves, and a collective mass burial pit within the general cemetery. The main aim is to assess whether people buried in the mass graves were rural immigrants, or if they were more likely to be the victims of plague (or another epidemic) who lived in Riga and its suburbs. The data produced (from dental disease assessments and isotope analyses) were compared within, as well as between, the contexts. Most differences em…

Identification of Lactobacilli from Deep Carious Lesions by Means of Species-Specific PCR and MALDI-TOF Mass Spectrometry

2014

SUMMARY Background: The aim of the present study was to compare MALDI-TOF results for the identification of 87 lactobacilli, isolated from soft or hard carious dentin from 70 first molars of 7- to 8-year-old children with those obtained by species-specific PCR. Methods: The 87 isolates were analyzed by MALDI-TOF MS (Microflex LT, MALDI Biotyper 3.0, Bruker Daltonik, Bremen, Germany), using a reference data base of 4110 strains including > 90 lactobacillus species. For the identification with species-specific PCR, oligonucleotide primers (16S rRNA) specific for L. casei, L. paracasei, L. rhamnosus, L. gasseri, L. plantarum, and L. acidophilus were used; type strains served as controls. The P…

A comparative quantitative & qualitative assessment in orthodontic treatment of white spot lesion treated with 3 different commercially available mat…

2019

Background To comparatively evaluate the esthetic improvement of white-spot lesions (WSLs) treated by: BiominF, CPP-ACP paste with fluoride & ICON resin infiltration, using Spectrophotometer & Diagnodent. Material and Methods The study was done using 72 sound permanent extracted premolars, divided into four groups (18 teeth per group). After taking the ethical approval the study was commenced. WSLs were created on human premolars and randomly assigned to four groups: Group A: Artificial Saliva, Group B: CPP-ACP with fluoride, Group C: BiominF, Group D: Resin infiltration (Icon). The color change (∆E) of each specimen was measured with a Spectrophotometer (VITA Easy Shade Compact), and fluor…

DMFT indekss un kariesa izplatība Latvijas Universitātes studentu zobārstniecības klīnikas pacientiem

2022

Mutes veselībai ir ļoti nozīmīgs iedzīvotāju labklājības faktors. Slikta mutes dobuma veselība var būt par iemeslu sāpēm, zobu zaudējumam, funkciju zudumumam un pazeminātai pašcieņai. Zobu kariess ir viena no divām visbiežāk sastopamajām mutes dobuma saslimšanām un zobu zaudējuma iemesliem. Epidemioloģiskie pētījumi, izmantojot dažādus starptautiski pieņemtus indeksus, lēš, ka globāli neārstēts kariess pastāvīgo zobos ir 2,3 miljardiem cilvēku un neārstēts kariess piena zobos - 532 miljoniem bērnu. Taču pētījumu pieaugušajiem ir daudz mazāk nekā bērniem, kas arī pamato darba mērķi - analizēt DMFT indeksu un kariesa izplatību pieaugušiem pacientiem, kuri apmeklē Latvijas Universitātes Studen…

Resultados La concentración mediana de fluoruro de las aguas minerales naturales españolas es de…

Determinación de ácido láctico en el dorso de la lengua: Su relación con la presencia de caries activa

2004

Resumen: Fundamento: el diagnostico de susceptibilidad a la caries es un reto que actualmente tienen que abordar los procedimientos diagnosticos. La presencia de acidos en el medio oral produce una reduccion del pH, siendo el acido lactico el maximo responsable de esta situacion. La posibilidad de detectar sus niveles en la boca puede plantearse como una medida diagnostico adecuada para estimar el riesgo individual frente a la caries. Objetivo y Metodologia: este estudio evalua, de forma preliminar, un test recientemente introducido en el mercado por la casa 3M (Clinpro Cario L-Pop) que permite medir mediante una escala ordinal la presencia de acido lactico en la superficie lingual. Para el…

Relación entre la caries, el índice de masa corporal y la clase social en niños españoles

2017

Abstract Objective: To determine the association between caries, body mass index (BMI) and social class in child population of the Valencia region (Spain) at 6, 12 and 15 years, and study. Methods: In a cross sectional study of 1326 children aged 6 (n = 488), 12 (n = 409) and 15 years (n = 433) who took part in the 2010 Oral Health Survey of the Valencia region, the ICDAS II criteria were employed for diagnosing and coding all the teeth examined. The quantitative BMI values on a continuous scale were grouped into 3 categories (normal weight, overweight, obese) based on a table adjusted for age and gender. The highest-ranking occupation of the parents was taken to indicate the social class o…

Cytotoxicity and dentin composition alterations promoted by different chemomechanical caries removal agents : a preliminary in vitro study

2021

Background The use of chemomechanical agents for caries removal has been indicated as a non-invasive treatment option; however, their possible deleterious effects on the dental-pulp complex have been insufficiently studied. This study assessed the direct cytotoxicity of two chemomechanical caries removal agents (Brix 3000™ - BX and Papacarie Duo™ - PD) on pulp cells from deciduous teeth, as well as to assess the morphology and chemical compositions of the dentin surface after the application of these materials. Material and methods The cells were seeded (50,000 cells/cm²) in a culture medium (DMEM with 10% fetal bovine serum - FBS). After 24 hours, the BX and PD materials were added to 1:20…

Caries arresting effect of silver diamine fluoride on dentine carious lesion with S. mutans and L. acidophilus dual-species cariogenic biofilm

2013

OBJECTIVES: This in vitro study investigated the effects of silver diamine fluoride (SDF) on dentine carious lesion with cariogenic biofilm. STUDY DESIGN: Thirty human dentine blocks were inoculated with Streptococcus mutans and Lactobacillus acidophilus dual-species biofilm to create carious lesion. They were equally divided into test and control group to receive topical application of SDF and water. After incubation anaerobically using micro-well plate at 37oC for 7 days, the biofilms were evaluated for kinetics, morphology and viability by colony forming units (CFU), scanning electron microscopy (SEM), and confocal microscopy (CLSM), respectively. The carious lesion underwent crystal cha…
