Background: Although reciprocating instrumentation has been extensively studied for permanent teeth, stronger evidence for its use in primary teeth is lacking.

Aim: The aim of this randomized clinical trial was to compare the efficacy of endodontic treatment in primary molars using reciprocating (RECIP) and manual (MAN) instrumentation techniques after 24 months.

Design: Primary molars with indication of endodontic treatment were randomly divided into two groups: MAN and RECIP.

The aim of this study was to compare the pulp vitality of primary teeth with deep caries treated with two restorative techniques. The restoration survival rate was also evaluated as a secondary outcome. Children aged from 4 to 8 years with at least one deep carious lesion in molars were selected at the Ibirapuera University dental clinic.

Roughness-tactile perception is part of activity assessment in initial-caries-lesions. Hypothesizing that a probe's design influences this examiner's assessment, four probes were designed. The aims of this study were to select the probe with highest inter-/intra-examiners' roughness-assessment agreement and to determine its diagnostic accuracy on artificial initial-caries lesions.

This methodological survey aimed to verify whether there is concordance among several Cariogram different risk models at different thresholds, comparing both children and adult populations and how each risk/protective factor weight on the overall caries risk profile. Three groups' data (two in children and one in adults) were obtained from previous studies, while a fourth, in young adults, was ad hoc enrolled. Different caries risk levels were assessed: a) three risk categories with two different thresholds as: "low risk"  =  61-100% or 81-100% chance to avoid caries, "moderate risk"  =  41-60% or 21-80% and "high risk"  =  0-40% or 0-20%, named model 1 and 2; b) four risk categories with two different thresholds as: "low risk"  =  61-100% or 76-100%, "moderate/low risk" = 41-60% or 51-75%; "moderate/high risk" = 21-40% or 26-50% and "high risk" = 0-20% or 0-25%, model 3 and 4; c) five risk categories as: "very low risk"  =  81-100%; "low risk"  =  61-80% "moderate risk" = 41-60%; "high risk" = 21-40% and "very high risk" = 0-20%, model 5.

Objective: This randomized clinical trial aimed to evaluate the influence of two caries diagnosis strategies, and subsequent management, on oral health-related quality of life (OHRQoL) of preschoolers. Additionally, the association of the OHRQoL outcomes with the clinician-centred primary outcome used in the main study was also explored.

Materials And Methods: This study refers to the OHRQoL secondary outcomes analyses of the so-called RCT 'CARDEC-1'.

Aim: The aim of this non-inferiority randomized clinical trial was to compare the efficacy of an iodoform-based paste (Guedes-Pinto -(GP)) as a filling material in pulpectomies of primary teeth, and a standard material composed by calcium hydroxide and iodoform (CaOH/Iodof paste; Vitapex ).

Design: A total of 104 teeth from 61 children (3-8 years old) were randomly allocated to two groups according to filling materials. Children were followed up for 24 months.

Article Synopsis
  • The study found that Early Childhood Caries (ECC) significantly affects the oral health-related quality of life (OHRQoL) in Mexican preschool children aged 3-5 years.
  • Caries prevalence was notably high at 82.2%, with 45% having dentinal lesions, indicating serious dental issues in this age group.
  • Factors such as attending rural private schools, having fewer meals per day, and unsupervised tooth brushing were linked to higher caries severity levels, emphasizing the role of socioeconomic and lifestyle influences on children's dental health.

Objective: To identify the best available approach to avoid initial caries lesions progression in primary teeth.

Materials And Methods: Search was performed in MEDLINE/Pubmed, Web of Science, Embase and CENTRAL databases until March 2021. Studies compared treatment options to avoid the initial caries lesion progression with at least 12 months of follow-up were included.

Background: To evaluate the clinical course and interventions required during two years of follow-up of dental surfaces of deciduous molars diagnosed, and consequently treated, by two different strategies: diagnosis made by clinical examination alone or associated with radiographs.

Methods: This is a secondary analysis of a two-arm randomized clinical trial with parallel groups related to the diagnostic strategy for caries detection in preschool children. 216 children (3-6 years old) were followed-up for two years.

Background: Visual inspection (VIS) with radiographic examination (RAD) is the recommended diagnostic strategy for detecting caries in children; however, this recommendation is based on accuracy studies. The authors conducted a clinical trial to compare the detection and subsequent treatment of carious lesions in primary molars performed with VIS alone and with RAD.

Methods: Children (3-6 years old) were randomly assigned to 2 groups according to the diagnostic strategy used for caries detection on primary molars: VIS or RAD.

Background: In the last decade, 3D virtual models have been used for educational purposes in the health sciences, specifically for teaching human anatomy and pathology. These models provide an opportunity to didactically visualize key spatial relations that can be poorly understood when taught by traditional educational approaches. Caries lesion detection is a crucial process in dentistry that has been reported to be difficult to learn.

This paper explains how to screen tooth wear in general practice using the Basic Erosive Wear Examination (BEWE) index. It explains how stakeholders in the UK acknowledged the convenience of the BEWE and that it could be recorded at the same time as the Basic Periodontal Examination (BPE). The article contains examples of anterior and posterior tooth wear for each BEWE score to help dentists in their evaluation.

Objectives: To evaluate the impact of radiographic examination on changes of treatment decision related to dental caries compared to decisions guided by visual inspection alone in primary molars.

Materials And Methods: A total of 126 children aged 3-6 years who had sought dental assistance were randomly selected and examined by two calibrated examiners using visual inspection. A treatment plan regarding dental caries was generated based on this assessment.

We aimed to evaluate whether children's caries experience exerts an influence on the performance of visual and radiographic methods in detecting nonevident proximal caries lesions in primary molars. Eighty children (3-6 years old) were selected and classified as having a lower (≤3 decayed, missing, or filled surfaces; dmf-s) or higher (> 3 dmf-s) caries experience. Two calibrated examiners then assessed 526 proximal surfaces for caries lesions using visual and radiographic methods.

Background: Although most clinical guidelines throughout the world indicate that clinicians take two bitewings for detecting caries lesions in primary molars of all children, evidence for this recommendation is essentially based on cross-sectional studies performed in laboratory settings or using convenience samples. The benefits and impact of performing radiographs on diagnosis and treatment decision of caries lesions in primary teeth, mainly considering relevant outcomes for patients, have not been evaluated yet. Thus, the aim of this randomized clinical trial will be to evaluate the impact of performing radiographic examination adjunct to the visual inspection for detecting and making treatment decision regarding caries lesions in primary teeth compared with visual inspection performed alone.

Background: In epidemiological surveys, a good reliability among the examiners regarding the caries detection method is essential. However, training and calibrating those examiners is an arduous task because it involves several patients who are examined many times. To facilitate this step, we aimed to propose a laboratory methodology to simulate the examinations performed to detect caries lesions using the International Caries Detection and Assessment System (ICDAS) in epidemiological surveys.
