A Comparison of Arch Length, Intercanine Width, Intermolar Width, and Interalveolar Width in Patients With Angle's Class II Division I Malocclusion With Shallow and Deep Palates.

Background and objective Palatal depth is significant as it impacts the intra-arch dimensions in patients with Angle's Class II Division 1 malocclusion. Hence, understanding this relationship is crucial for developing targeted orthodontic treatment plans, to optimize dental alignment and overall facial aesthetics. This study aimed to compare the arch length, intercanine width, intermolar width, and interalveolar width in patients with Class II Division 1 malocclusion with deep palates and those with shallow palates.

Comparative assessment of surface irregularities of enamel after bonding with different techniques followed by three composite removal methods: An atomic force microscopic study.

Background: To compare and assess the enamel surface roughness by Atomic Force Microscopy between ceramic and metal brackets after adhesive removal with 3 different methods.

Methods: 90 extracted premolars were collected and divided equally into 3 groups G, Y, and R. With group G bonded with metallic brackets (using primer and Transbond XT), group Y with ceramic brackets (primer and Transbond XT), and group R with ceramic brackets (silane and Transbond XT).

Correlation of Palatal Index With Pharyngeal Airway in Various Skeletal Patterns.

Introduction This retrospective study aimed to correlate palatal index with pharyngeal airway in class I, class II and class III skeletal patterns. Materials and methods A total of 30 individuals with a mean age of 17.5 years were included in the study.

Comparison of Alveolar Bone Thickness, Sagittal Root Positions, and Arch Forms in Class I, II, and III Malocclusions: A Cephalometric Study.

Objective: This retrospective study aimed to evaluate the sagittal root position, arch shapes, and alveolar bone thickness in classes I, II, and III of skeletal patterns.

Material And Methods: Alveolar bone thickness, sagittal root placements, and arch morphologies in classes I, II, and III malocclusions were measured using 30 study models and 30 lateral cephalograms, both with a mean age of 16.5 years.

Cemental annulation: An approach to age estimation in transverse and longitudinal sections using three different microscopes.

Background: Estimation of age is an important aspect in determining a person's identity. Since teeth are resistant to decay and degradation, estimation of age using dental structures may be a valuable tool in human identification. Recent research suggests that tooth cemental annulation could be used as an effective method for age estimation than other morphologic or histological parameters.

Evaluation of as matrix metalloproteinase inhibitor in human dentin with and without dentin-bonding agent: An study.

Background: Proper hybrid layer formation lays the foundation of resin-dentin bonding. The resin infiltration in demineralized dentin collagen couples with the adhesive/resin composites in the mineralized dentin surface. However, the activation of enzymatic activity in the collagen matrix can degrade the hybrid layer.

Occlusal stress distribution in the human skull with permanent maxillary first molar extraction: A 3-dimensional finite element study.

Introduction: The objective of this research was to analyze the effect of orthodontic treatment with maxillary permanent first molar extraction on the occlusal stress distribution and displacement in the human skull.

Methods: A 3-dimensional finite element model was constructed on the basis of a computed tomography scan, and it was used as the pretreatment model. The software used for geometric modeling was Solid Works (Dassault Systèmes, Paris, France).

Coronavirus Disease 2019-Challenges Today and Tomorrow in Orthodontic Practice: A Review.

From the start of 2020, the world has witnessed the biggest health and humanitarian crisis in the modern century named coronavirus disease 2019. The rapid spread of infection created chaos and confusion across the globe. Like all other health professions, a timely and major reorganization of orthodontic services is challenging.
