Department of Oral Diagnosis, Piracicaba Dental School, University of Campinas, Av. Limeira, 901, Areião, Piracicaba, SP, 13414-903, Brazil.
Objectives: To assess the influence of a handheld X-ray unit in the diagnosis of proximal caries lesions using different digital systems by comparing with a wall-mounted unit.
Methods: Radiographs of 40 human teeth were acquired using the Eagle X-ray handheld unit (Alliage, São Paulo, Brazil) set at 2.5 mA, 60 kVp and an exposure time of 0.

Oral cancer detection is based on biopsy histopathology, however with digital microscopy imaging technology there is real potential for rapid multi-site imaging and simultaneous diagnostic analysis. Fifty-nine patients with oral mucosal abnormalities were imaged in vivo with a confocal laser endomicroscope using the contrast agents acriflavine and fluorescein for the detection of oral epithelial dysplasia and oral cancer. To analyse the 9168 images frames obtained, three tandem applied pre-trained Inception-V3 convolutional neural network (CNN) models were developed using transfer learning in the PyTorch framework.

In response to the increasing prevalence of dental diseases, dental health, a vital aspect of human well-being, warrants greater attention. Panoramic X-ray images (PXI) and Cone Beam Computed Tomography (CBCT) are key tools for dentists in diagnosing and treating dental conditions. Additionally, deep learning for tooth segmentation can focus on relevant treatment information and localize lesions.

Department of Ophthalmology, Hospital das Clínicas - Empresa Brasileira de Serviços Hospitalares, Federal University of Pernambuco, Recife, Brazil.
Background: Oculodentodigital dysplasia (ODDD) is a rare syndrome that causes a constellation of facial, ophthalmic, dental, and limb abnormalities. Variants in the gap junction alpha-1 () gene have been described in patients with ODDD. Hereby we present the ocular manifestations in a patient with recessive ODDD due to a novel homozygous frameshift variant in .

Department of Neurosciences, School of Dentistry, University of Padua, Padua, Italy.
Objective: This study aimed at investigating implant survival rate and marginal bone loss (MBL) around extra-short implants. The impact of the loading protocol and of the use of an intermediate abutment was also evaluated, to explore possible differences in terms of the outcome measures.
Materials And Methods: Patients with single or multiple mandibular or maxillary posterior edentulism rehabilitated using extra-short 5-6 mm long implants were included.
