Miswak-Infused Glass Ionomer Cement: A Comparative In Vitro Analysis of Antibacterial Efficacy and Compressive Strength.

BACKGROUND: Glass ionomer cement (GIC) restorations are commonly used in primary dentition, due to their aesthetic appeal, self-adhesive nature, and biocompatibility. However, the material's limited antibacterial activity and inadequate mechanical strength highlight the necessity for modifying the material. AIM: The study aims to evaluate and compare the antimicrobial potency and compressive strength of GIC-incorporated Miswak extract with that of conventional GIC. MATERIALS AND METHODS: After obtaining the Miswak extract, a modified GIC was formulated by combining the extract with the conve…

Accelerated Canine Retraction by Using Mini Implant With Low-Intensity Laser Therapy.

Background The continuous increase in demand for reduced treatment times has led researchers to think in terms of "accelerated orthodontics. … gy This study was conducted using the split-mouth method, which included 20 patients with permanent dentition who required first premolar extractions. A miniscrew implant was placed on both the right and left sides for maximum anchorage. Irradiation doses were applied on days 0, 3, 7, and 14 of the first month. Subsequently, irradiations were given every 15 …

Feeding behaviour and functional morphology of the neck in the long-snouted aquatic fossil reptile Champsosaurus (Reptilia: Diapsida) in comparison with the modern crocodilian Gavialis gangeticus.

The extinct freshwater choristoderan reptiles Champsosaurus and Simoedosaurus are characterised by large body size and an elongated snout. T … t. However, inertial feeding is less likely to have occurred in this genus, and the aligned palatal dentition may have aided the lingual transport of prey into the mouth. Simoedosaurus, on the other hand, appears to have been less specialised, with a neck that combined lateral and dorsolateral flexion, a move that could have been effective in catching both …

Laboratory mice are staples for evo/devo and genetics studies. Inbred strains provide a uniform genetic background to manipulate and underst … . Future work will incorporate more anatomical detail (such as individual cranial bones, turbinals, dentition, middle ear ossicles) and more diversity into the template.

Esthetic outcomes following immediate and early implant placement in the anterior maxilla--a systematic review.

PURPOSE: The objectives of this systematic review are (1) to quantitatively estimate the esthetic outcomes of implants placed in postextract … with implants placed after extraction of teeth in the maxillary anterior and premolar areas of the dentition. Recession of the midfacial mucosa is a risk with immediate (type 1) placement. Further research is needed to investigate the most suitable biomaterials to reconstruct the facial bone and the relationship between long-term mucosal stability and pres …

Morphologic analysis of third-molar maturity by digital orthopantomographic assessment.

Accurate timing of the eruption of first and permanent teeth is an important parameter in forensic odontology to establish the age of dead o … develop.

The Frankfurt proportion: The ratio between anterior tooth size and occlusal vertical dimension.

STATEMENT OF PROBLEM: Extensive tooth wear compromises both incisal length and occlusal vertical dimension (OVD). Evidence-based reference values correlating anterior tooth morphology with OVD are needed to guide reconstruction in patients with severely worn dentitions. PURPOSE: The purpose of this clinical study was to analyze correlations between anterior tooth dimensions and OVD in young adults, assess the validity of commonly used reference ratios, and develop updated morphometric guidelines for clinical application. MATERIAL AND METHODS: Eighty-one participants underwent digital intraor…

Clinical accuracy of three intraoral scanners for determining an increased vertical dimension of occlusion: A pilot study.

STATEMENT OF PROBLEM: The accuracy of maxillomandibular relationships captured by intraoral scanners (IOSs) has been previously evaluated under in vitro conditions; however, the accuracy of different IOSs in registering an increased vertical dimension of occlusion under clinical conditions remains unclear. PURPOSE: The purpose of this in vivo study was to assess the accuracy of maxillomandibular relationship records at an increased vertical dimension of occlusion using different IOSs. MATERIAL AND METHODS: A participant dentition was digitized using an IOS (PrimeScan) to obtain a reference s…

Perceptions, Practices, and Challenges of Interceptive Orthodontics Among Indian Pediatric Dentists: A Cross-Sectional Survey.

Background Interceptive orthodontics in the primary and mixed dentitions can reduce the severity of developing malocclusions and simplify later comprehensive treatment. Pediatric dentists are ideally placed to recognize early malocclusion and initiate or coordinate interceptive care, yet data on how they perceive and implement interceptive orthodontics in India are limited. Aim This study aimed to evaluate Indian pediatric dentists' perceptions, clinical practices, and perceived barriers related to interceptive orthodontics. Materials and methods A descriptive, questionnaire-based, cross-secti…

Assessment of evidence from teeth and the alveolar bone of skulls.

A notable lack of agreement on a standardised criterion for representing changes in alveolar bone persists, which limits its application in forensic dentistry. This study aimed to describe the data on loss of tooth substance and alveolar bone in skulls. Dental and trabecular bone information from 28 skulls from the German Helmer skull collection was collected through dental charting, intraoral photographs taken with a DSLR camera (Nikon D5600, Nikon Corporation, Japan), and small radiographs obtained using a handheld dental X-ray device (Nomad Pro 2, Kavo Kerr, Biberach, Germany).

… The literature on these distinctions in bone is abundant, as opposed to human dentition 61 . For the prior, the assessment of the timing of injuries is dependent upon the evidence of their healing and remodelling, or the lack thereof 61 . … These findings highlight the complex aetiology of tooth wear and its predominance in anterior dentition. Also, the high number of missing posterior teeth in this study could have contributed to this disparity in comparison. …
