AI Article Synopsis
- Study aimed to evaluate the effectiveness of different radiographic techniques for detecting proximal dental caries using 100 extracted human teeth.
- Two observers scored the radiographs against a histological gold standard, analyzing their accuracy with ROC curve analysis.
- Findings revealed that the improved interproximal panoramic and extraoral bitewing radiographs outperformed conventional panoramic radiography, especially for patients unable to undergo intraoral imaging.
Article Abstract
Objectives: Dental caries are common and have a high incidence among populations. Radiographs are essential for detecting proximal caries. The best technique should be recognized for accurate detection of caries. The aim of this study was to compare the accuracy of detection of proximal caries using intraoral bitewing, extraoral bitewing, improved interproximal panoramic, improved orthogonality panoramic and conventional panoramic radiographs.
Materials And Methods: In this descriptive cross sectional study, 100 extracted human teeth with and without proximal caries were used. Intra and extraoral radiographs were taken. Images were evaluated and scored by two observers. Scores were compared with the histological gold standard. The diagnostic accuracy of radiographs was assessed by means of receiver operating characteristic (ROC) curve analysis (P<0.05).
Results: Microscopic evaluation of proximal surfaces revealed that 54.8% of the surfaces were sound and 45.2% were carious (with different depths). The differences in the area under the ROC curve (Az value) among the five techniques were not statistically significant.
Conclusion: Improved interproximal panoramic and extraoral bitewing radiographs were superior to conventional panoramic radiography for detection of proximal caries ex vivo and should be considered for patients with contraindications for intraoral radiographs.

Effect of Glass Fiber Reinforcement on Marginal Microleakage in Class II Composite Restorations: An In Vitro Pilot Study.
Dent J (Basel)

Polymerization shrinkage of composite resins affects the marginal closure of direct dental restorations. It is responsible for developing secondary caries and indirectly affects the survival rate of restorations. This study aims to investigate the null hypothesis, which states that there are no significant differences in the marginal microleakage of Class II restorations when examined in vitro using different dental adhesives, whether the restoration material used is a composite with glass fiber reinforcement or not.

Article Synopsis
- Oral health has a crucial impact on overall well-being, with a growing burden of oral diseases such as dental caries and periodontal disease in Saudi Arabia due to lifestyle changes.
- The study aims to investigate both direct (proximal) and indirect (distal) factors that influence oral pain (OP) and self-rated oral health (SROH) among different age groups in Saudi Arabia, using data from a national health survey conducted in 2017.
- Findings reveal a notable discrepancy where a high percentage of respondents rated their oral health positively despite reporting oral pain, with tooth brushing frequency strongly linked to lower OP and better SROH, while sugar consumption negatively affected oral health across ages.
Introduction: The aim of this in vitro study was to evaluate the accuracy of near-infrared imaging (NIRI) generated by the iTero Element 5D scanner for detecting proximal caries lesions in deciduous molars, compared with visual inspection (VI), bitewing radiography (BW) and histological examination (HT) (reference standard).
Methods: Sound deciduous molars and those with caries lesions (ICDAS 0 to 5) on the proximal surface were included, while teeth with marginal crest breakdown, restoration on the mentioned surfaces, or extensive dentin resorption were excluded. A total of 182 deciduous molars, divided into 91 pairs of first and second molars, were evaluated by two blinded examiners.
Objective: Aim: Assessment of dental caries and its impact on the level of dental health of children aged 15-18 years of Upper Tysa region, who constantly live in conditions of combined negative effects of factors of natural and technological genesis.
Patients And Methods: Materials and Methods: During the dental examination, the incidence of dental caries in 360 children aged 15-18 years from various biogeochemical zones of the cross-border region of the Upper Tysa region was studied and assessed using the International Caries Detection and Assessment System - ICDAS II (International Caries Detection and Assessment System).
Results: Results: It was found that the use of physiologically suboptimal drinking water from decentralized water resources is among the environmental determinants of the state of dental health of children in the Upper Potyssia.
Minimal intervention dentistry for treating primary teeth: a survey study among members of the Israeli Society of Paediatric Dentistry.
Eur Arch Paediatr Dent
December 2024
Department of Pediatric Dentistry, Hadassah Medical Center, Faculty of Dental Medicine, Hebrew University of Jerusalem, P.O.B. 12272, 9112102, Jerusalem, Israel.
Purpose: To assess the attitudes of dentists in Israel to minimal intervention on primary teeth.
Methods: For this cross-sectional study, data were accessed from questionnaires that were completed anonymously by members of the Israeli Society of Paediatric Dentistry. For four clinical scenarios, the respondents were asked to describe the stage at which they would intervene, the type of preparation they would utilize, and the restorative materials they would use.
