This study aimed to evaluate by microCT the preparation of the artificial teeth (ATs), TrueTooth®, versus natural teeth (NTs): (1) the time and number of pecking movements needed for preparation; (2) the root canal volume increase; (3) if the pul...
New minimally invasive endodontic cavities have been described and proposed to preserve dentin (and enamel) through strategic access, including point endodontic access cavity (PEAC). There is no consensus to what extent PEAC contributes to tooth&rsqu...
Background: Missed second mesiobuccal second (MB2) canals are a recognized contributor to endodontic failure, and enhanced visualization may facilitate their detection. This study evaluated the influence of magnification devices and operator experien...
Background and Objectives: Evaluating jaw augmentation procedures usually necessitates pre- and postoperative tomographic imaging. Ethical considerations emphasize minimizing radiation exposure. Given that panoramic radiographs (PR, 2D) offer a lower...

In diagnostic accuracy studies, the test of interest is typically applied only once in each patient. This paper illustrates some possibilities that arise when diagnoses are carried out by a sufficiently large number of multiple raters. In a dental st...
Early diagnosis and timely management of tooth or dental material wear is imperative to avoid extensive restorations. Previous studies suggested different methods for tooth wear assessment, but no study has developed a three-dimensional (3D) superimp...
Retrotransposon insertion patterns facilitate a virtually homoplasy-free picture of phylogenetic history. Still, a few most likely random parallel insertions or deletions result in rare cases of homoplasy in primates. The following question arises: h...
The identification of unknown human remains represents an important task in forensic casework. If there are no clues as to the identity of the remains, then the age, sex, and origin are the most important factors to limit the search for a matching pe...
Traditional methods for age determination of wildlife include either slicing thin sections off or grinding a tooth, both of which are laborious and invasive. Especially when it comes to ancient and valuable museum samples of rare or extinct species,...
Background and Objectives: Ectodermal dysplasia (ED)—a genetic disorder—is characterized by severe tooth deficiency. We compared the mandibular volume and the sagittal and horizontal mandibular widths between patients with ED (ED group) a...
The precise measurement of crankshaft torsional vibration is critical for diesel engine reliability, yet it is often compromised by systematic errors from toothed disc runout. To address this challenge, this paper elucidates the dual mechanism of the...
Aim: The increasing popularity of do-it-yourself (DIY) tooth whitening using natural products has raised concerns regarding their effectiveness and potential adverse effects on enamel. This in vitro study aimed to compare the colour changes produced...
The Invisalign® system (SmartForce® G8) aims to guarantee aesthetics and provide good orthodontic treatment results. Dentoalveolar expansion is possible with clear aligners and can be used to correct dentoalveolar crossbite, resolve crowding...
In dental research, the morphometric assessment of restorations is a challenge. This also applies to the assessment of the length of interfacial adhesive defects in composite restorations as a measure of tooth-restoration bond failure. The determined...
Background: Furcation involvement (FI) represents one of the most challenging conditions in periodontal therapy due to the anatomic complexity of multi-rooted teeth and the progressive interradicular attachment loss that compromises long-term tooth s...
The current study aimed to implement and validate an automation system to detect carious lesions from smartphone images using different one-stage deep learning techniques. 233 images of carious lesions were captured using a smartphone camera system a...

In recent years, there has been an increase in the incidence of dental wear; thus, an early diagnosis is important. Conventional methods of diagnosis are based primarily on the visual abilities of the dentist, and therefore the use of new technologie...
Pediatric odontogenic tumors are rare but are frequently overlooked because they often mimic simple cysts on routine radiographic examinations. The radiographic appearance on panoramic imaging and cone-beam computed tomography (CBCT) frequently does...

Due to the high prevalence of periodontitis, dentists have to face a larger group of patients with periodontally compromised dentitions (PCDs) characterized by pathologic tooth migration and malocclusion. Impression taking in these patients is challe...
Background: Maxillary transverse deficiency is a common skeletal discrepancy in orthodontic patients that often requires expansion therapy for correction. Failure to address this condition during growth may compromise the orthopedic prognosis, freque...
Predictable pulp-dentin regeneration continues to represent a major challenge in regenerative endodontic procedures (REPs). Although collagen-based scaffolds are widely investigated for their excellent biocompatibility, their ability to deliver consi...
The limitations on the use of fluoride therapy in dental caries prevention has necessitated the development of newer preventive agents. This review focusses on the recent and significant studies on P11-4 peptide with an emphasis on different applicat...
The genus Crocidura represents a remarkable model for the study of chromosome evolution. This is the case of the lesser white-toothed shrew (Crocidura suaveolens), a representative of the Palearctic group. Although continuously distributed from Siber...
Background and objectives: Enamel matrix derivative (EMD) is produced from developing porcine tooth buds and represents a complex of low-molecular-weight hydrophobic enamel proteins. EMD is widely applied in periodontal regeneration. Osteoclasts are...
Aim: Root canal treatment preserves the natural tooth and avoids the consequences of extraction, yet its acceptance depends on public knowledge, attitudes, and perceptions. This cross-sectional online survey assessed the knowledge, attitudes, and exp...
Background/Objectives: To assess and compare the knowledge of and attitudes toward erosive tooth wear (ETW) among university students at the Portuguese University Fernando Pessoa (UFP). Methods: Cross-sectional, prospective pilot study approved by th...
Background/Objectives: Machine learning (ML) models predicting the risk of refinement (i.e., a subsequent course of treatment being necessary) in clear aligner therapy (CAT) were developed and evaluated. Methods: An anonymized sample of 9942 CAT pati...
Introduction: The aim of the study was to compare the Intubrite laryngoscope and the standard Macintosh blade laryngoscope (MCL) used by persons with no clinical experience in simulated hospital and non-hospital conditions on a manikin model. Materia...
Objectives: To examine the effects of surface treatments on the color stability, surface roughness, surface gloss, and wettability of monolithic polychromatic material jetting (MJT) 3D-printed denture material. Material and Methods: Twenty-one color...
