INTRODUCTION: External apical root resorption (EARR) is often an undesirable sequela of orthodontic treatment. Prior studies have suggested a substantial link between EARR and certain genetic components. Single nucleotide polymorphisms (SNPs) may play a role as predisposing factors. This study aimed to investigate the potential association between EARR and various SNPs. METHODS: The study included 218 orthodontic participants of all malocclusions who had available pretreatment and posttreatment panoramic radiographs...

INTRODUCTION: Orthodontists have many techniques to treat anterior open bites and must involve patients in making treatment decisions. This study aimed to investigate orthodontic treatment plan acceptance by United States adults with anterior open bites and to identify associations between treatment acceptance and patient demographics and dentofacial characteristics. METHODS: A prospective, observational cohort study enrolled the patients of 91 orthodontic providers...

INTRODUCTION: This study aimed to determine whether prescribed molar intrusion, with or without virtual occlusal bite-blocks (BB), resulted in actual molar intrusion and assisted with anterior open bite (AOB) correction in adult patients treated with Invisalign clear aligners (Align Technology, Santa Clara, Calif). METHODS: A retrospective study was conducted with 36 adult patients with AOB. Subjects were divided into 2 treatment groups: planned molar intrusion (PMI) and no-PMI (No-PMI)...

INTRODUCTION: This study aimed to evaluate the effectiveness of Dental Monitoring (DM) (Dental Monitoring SAS, Paris, France) compared with conventional monitoring (CM) during active orthodontic treatment. METHODS: The Peer Assessment Rating (PAR) index was used to evaluate the pretreatment and posttreatment records of 51 patients, with 26 in the CM group and 25 in the DM group. The change in weighted PAR was analyzed to assess the effectiveness of treatment. RESULTS: The chi-square test revealed that the CM group had a higher percentage of patients in the great improvement category compared with the DM group...

INTRODUCTION: White spot lesions (WSLs) represent a prominent pathology encountered during orthodontic treatment, originating from enamel demineralization induced by the accumulation of bacterial biofilms. The previously developed bioinspired enamel coating form of self-assembling antimicrobial peptide D-GL13K exhibited antimicrobial activity and enhanced acid impermeability, offering a potential solution to prevent demineralization. The primary aim of this investigation is to assess the in vivo anti-demineralization properties and biocompatibility of the D-GL13K coating...

INTRODUCTION: This study evaluated the probability of developing malocclusions in mixed dentition. METHODS: A longitudinal study was conducted with 598 children (aged 5 years) in deciduous dentition. The children were followed for 3 years until mixed dentition (aged 8 years). Overjet, overbite, and transversal relations were evaluated. Bayesian models were used to analyze the data and estimate the parameters. RESULTS: The parameter θ was used for the distributions, indicating the probability of presenting a given condition with a credibility index (ICr) of 95%...

INTRODUCTION: The accuracy of tooth segmentation in intraoral scans is crucial for performing virtual setups and appliance fabrication. Hence, the objective of this study was to estimate and compare the accuracy of automated tooth segmentation generated by the artificial intelligence of dentOne software (DIORCO Co, Ltd, Yongin, South Korea) and Medit Ortho Simulation software (Medit Corp, Seoul, South Korea). METHODS: Twelve maxillary and mandibular pretreatment dental scan sets comprising 286 teeth were collected for this investigation from the archives of the Department of Orthodontics, Faculty of Dentistry, Alexandria University...

INTRODUCTION: This study aimed to analyze the comprehensive maxillofacial features of patients with skeletal Class III malocclusion and facial asymmetry to develop a classification system for diagnosis and surgical planning. METHODS: A total of 161 adult patients were included, with 121 patients in the asymmetry group (menton deviation >2 mm) and 40 patients in the symmetry group (menton deviation ≤2 mm). Twenty-eight variables were determined, including transverse translation, roll and yaw of each facial unit, transverse width, mandibular morphology, and transverse dental compensation...

INTRODUCTION: This study evaluated the labial and lingual cortical bone remodeling characteristics of mandibular central incisors after retraction, which remain controversial among orthodontists. METHODS: Cortical bone remodeling and central incisor movement of 33 patients (aged 23.64 ± 4.30 years) who underwent mandibular first premolar extraction and incisor retraction at the crestal (S1), midroot (S2), and apical (S3) levels were analyzed using superimposed cone-beam computed tomography images on the basis of voxel-based registration of the mandibular stable region...

INTRODUCTION: Interproximal reduction (IPR) damages the caries protective superficial layer of the enamel, making the enamel surface prone to caries because of the increase in surface roughness. Remineralizing solutions can help in preventing these undesirable side effects. Therefore, this study aimed to compare the effect of nanohydroxyapatite (nHAp) and sodium fluoride (NaF) application on enamel remineralization after IPR and to evaluate changes in surface roughness, composition, and microhardness of the treated enamel...

INTRODUCTION: This study aimed to design an artificial intelligence (AI) system for dental occlusion classification using intraoral photographs. Moreover, the performance of this system was compared with that of an expert clinician. METHODS: This study included 948 adult patients with permanent dentition who presented to the Department of Orthodontics, School of Dentistry, Mashhad University of Medical Sciences, during 2022-2023. The intraoral photographs taken from the patients in left, right, and frontal views (3 photographs for each patient) were collected and underwent augmentation, and about 7500 final photographs were obtained...

INTRODUCTION: The objective of this study was to identify the soft-tissue profile changes and the potential pretreatment cephalometric parameters that clinicians could use to predict the lip response after premolar extraction treatment in adult patients. METHODS: Pretreatment and posttreatment lateral cephalograms of 75 white patients treated with premolar extractions were analyzed. The following initial cephalometric measurements were recorded: upper and lower lip to E-plane, vermilion thickness, lip length, maxillary and mandibular incisor inclination, and mentolabial and nasolabial angle...
