This case report refers to an 11-year-old boy with avulsion of the upper left central and lateral incisors. The teeth were replanted after 4 h, splinted with a semi-rigid splint for 12 days, and then endodontically treated. Severe progressive root resorption was seen after 2 years and the teeth were extracted. The boy had a normal occlusion with spacing in both jaws and slight protrusion of the anterior teeth. The treatment objectives were to close some of the spaces by mesial movement of the buccal segments in the upper jaw to minimize bone loss for a future single osseointegrated implant. Fixed appliance in combination with a removable plate was used for the mesial movements, levelling, and alignment of the upper jaw. Fixed appliance in the lower jaw and Class II traction were used for the final adjustment of the occlusion. A good occlusion with coincident upper and lower midlines and up-righted anterior teeth were achieved. A Maryland bridge was performed as a temporary solution for a future osseointegrated implant.

Jansen metaphyseal chondrodysplasia: analysis of craniofacial manifestations.
JBMR Plus

Radiology and Imaging Sciences, National Institutes of Health Clinical Center, National Institutes of Health, Bethesda, MD 20892, United States.
Jansen metaphyseal chondrodysplasia (JMC) is an ultra-rare disorder caused by constitutive activation of parathyroid hormone type 1 receptor (PTH1R). We sought to characterize the craniofacial phenotype of patients with the disease. Six patients with genetically confirmed JMC underwent comprehensive craniofacial phenotyping revealing a distinct facial appearance that prompted a cephalometric analysis demonstrating a pattern of mandibular retrognathia.

Objective: This study aimed to evaluate the positional and morphological changes in the temporomandibular joint (TMJ) in adult patients with skeletal Class I malocclusion treated with fixed orthodontic appliances (FAs) and clear aligners (CAs), both with and without premolar extractions.
Methods: This retrospective study involved 120 adult patients divided into non-extraction and extraction groups, each further subdivided equally into those treated with FAs and CAs. Cone beam computed tomography (CBCT) was used to assess the TMJ measurements before (T0) and after treatment (T1).
Objectives: To: 1) analyze possible differences in the CIEDE2000 lightness, chroma and hue of the gingiva at the free gingival margin (FGM) and the middle zone of keratinized gingiva (MZ) between participants with an ISFP in the maxillary anterior region and participants with natural dentition and healthy gums; and 2) examine the perceptibility/acceptability of the differences in CIEDE2000 lightness, chroma and hue and in overall color, using the Euclidean and CIEDE2000 formulae.
Methods: The L*, a* and b* color coordinates were measured in 60 adult participants (30 with an ISFP and 30 with healthy teeth and gums) using a Spectroshade™ Micro spectrophotometer. From these coordinates, the changes in lightness (ΔL'), chroma (ΔC') and hue (ΔH') CIEDE2000 between the participants with and without an ISFP were quantified.

Objectives: To report up to 9-year results of a prospective and retrospective study on non-invasive full-mouth rehabilitation of worn dentition with PICN CAD-CAM restorations using the One-Step No-Prep technique. The secondary objective is to evaluate the influence of restoration thickness on fracture of restorations.
Methods: A total of 580 Vita Enamic restorations (218 anterior and 362 posterior; 260 monoblock (MO) and 320 multiColor (MC)) in 24 patients were clinically evaluated once a year (up 9 months to 9 years) according to FDI criteria.
Colorimetric analysis of intraoral scans: A novel approach for detecting gingival inflammation.

Discipline of Periodontics, School of Dentistry, University of São Paulo, São Paulo, Brazil.
Background: Gingivitis, a widely prevalent oral health condition, affects up to 80% of the population. Traditional assessment methods for gingivitis rely heavily on subjective clinical evaluation. This study seeks to explore the efficacy of interpreting the color metrics from intraoral scans to objectively differentiate between healthy and inflamed gingiva.
