Background: Most tooth cavities start to develop inside pits and fissures where brushing, saliva, fluoride toothpaste or mouthwashes have no access. Therefore, 3D morphology of pits and fissures is an important subject to be studied in relation to maintaining proper oral hygiene.
Objective: This study aimed to present high resolution images of pits and fissures in human teeth using a laboratory-based micro X-ray Computed Tomography (mXCT) and also to present the basic structure evaluation that could be obtained.
Methods: Three human wisdom teeth were examined. Two different set-ups were used in this study achieving resolution of 14.59 μm (Field of View of 14.9 mm) and resolution of 4.43 μm (FOV of 4.5 mm) respectively. Automated segmentation was performed for further evaluation to distinguish between empty space (pits and fissures) and the filled space (enamel).
Results: The 3D tomography results demonstrate detailed morphology with accurate dimensions and the locations of the pits and fissures, which is important to investigate the relationship with tooth decay that mostly starts deep inside pits and fissures.
Conclusions: Segmentation from the mXCT imaging of pits and fissures provides obvious visual evidence to help in promotion of oral health and to improve personal tooth care in preventive treatment protocols.

Dental caries remains a significant public health challenge in Romania, with recent studies reporting a prevalence of 40% in children's permanent teeth, with 90% of cases untreated. This study aimed to evaluate the dental status of the first permanent molars in children aged 11-12 years. This cross-sectional study was conducted over 12 months at the Integrated Center for Dental Medicine in Târgu Mureș and two private clinics in Transylvania.

Materials And Methods: One hundred sound third molars have been sealed as follows: group 1 (n = 20), light-cured resin sealant at room temperature, group 2 (n = 20), light-cured resin sealant, preheated to 41.0°C, group 3 (n = 20), light-cured resin sealant, preheated to 51.
Background: Dental caries remains the most prevalent chronic disease worldwide. Hence the importance of detecting and evaluating caries and combining this with additional diagnostic methods to ensure the best treatment. The main objective was to study what is the sensitivity and specificity for detecting initial and cavitated caries lesions by students in third, fourth and fifth year of the Degree in Dentistry at the University of Barcelona, analysing if there is any difference between the diagnoses and treatments among the different years and each student's clinical experience.

Background: Pit and fissure sealant is a micro-invasive modality for treating deep and retentive pits and fissures to prevent and/or stop occlusal caries. Every effort needs to be done to enhance sealant retention and survival. The aim of this research is to assess the retention rate of giomer S-PRG filler containing pit and fissure sealant applied with or without etching.
