Musée de la Cour d'Or, Metz, France, possesses a female skull bearing a gold wire dental appliance claimed in a 1934 article on the history of dental prosthetics to be 'probably' Merovingian in origin. Inquiries in 2017 revealed current museum curators were unaware of this claim but were skeptical of such dating suggesting scientific analysis might provide clarity. Carbon dating of a tooth from the skull was carried out placing the artifact in the mid seventeenth-late eighteenth centuries while Metz historical records reveal the find site was occupied by a convent of nuns for most of C14 dated period. Strontium isotopic analysis indicates the woman was a local of the Metz region while fluorine analysis indicates exposure to fluoride early in life. Oral health status and the dentistry indicate the woman was of high social status.

Introduction: This study aimed to evaluate the stability of palatal rugae patterns after slow maxillary expansion (SME) treatment and the reliability of the rugae region as a reference region in digital superimposition.
Methods: The SME group comprised 21 subjects with Angle Class I or Class II dental malocclusion with unilateral or bilateral crossbite and constricted maxilla and were selected before the pubertal peak. Intraoral scans were captured via the intraoral scanner iTero Element software (version 1.

Good oral hygiene is crucial during treatment with fixed appliances, emphasising the need for additional or alternative oral health methods during orthodontic treatment. This study investigates the effect of essential oil (EO)-based preparations on biofilm adhesion to orthodontic archwires. Five identical-sized orthodontic archwires of different materials were tested using therapeutic and preventive applications of essential oils.

The finite element method (FEM) is an advanced numerical technique that can be applied in orthodontics to study tooth movements, stresses, and deformations that occur during orthodontic treatment. It is also useful for simulating and visualizing the biomechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios. The objective of this research was to analyze the mechanical behavior of teeth, tissues, and orthodontic appliances in various clinical scenarios.

Background: Proper torque control is crucial to the outcome of orthodontic treatment. This study aimed to employ finite element analysis to compare the torque capabilities of a novel spherical self-ligating bracket with a lock-hook system against those of commonly used passive self-ligating and conventional bracket systems, as well as to reveal the biomechanical changes in the periodontal ligament (PDL) during torque expression.
Methods: A maxillary right central incisor, along with its PDL and alveolar bone, were modeled.

Background: There are different intraoral appliances for cessation of thumb/finger sucking habit, but they have many disadvantages and to overcome it, extra oral appliances with colourful and attractive shape were developed. Electronic habit reminder in the form of wristwatch with alarming sound was assessed in cessation of thumb/finger sucking habit in children versus palatal crib after 6 and 9 months.
Methods: This study is a randomized clinical pilot study, with allocation ratio 1:1 parallel group.
