Unsupervised Anomaly Detection of Paranasal Anomalies in the Maxillary Sinus [PDF]
arXiv, 2022 Deep learning (DL) algorithms can be used to automate paranasal anomaly detection from Magnetic Resonance Imaging (MRI). However, previous works relied on supervised learning techniques to distinguish between normal and abnormal samples. This method limits the type of anomalies that can be classified as the anomalies need to be present in the training ...

TWO ROOTED MAXILLARY LATERAL INCISOR
UNIVERSITY JOURNAL OF DENTAL SCIENCES, 2020 Maxillary lateral incisors are generally considered as a tooth with a single root and single canal. This is not true in all cases as case reports have advocated maxillary lateral incisors showing two roots with two or three root canals, Thorough knowledge of the internal and external dental anatomy and its variations is essential ...

Supervised Contrastive Learning to Classify Paranasal Anomalies in the Maxillary Sinus [PDF]
arXiv, 2022 Using deep learning techniques, anomalies in the paranasal sinus system can be detected automatically in MRI images and can be further analyzed and classified based on their volume, shape and other parameters like local contrast. However due to limited training data, traditional supervised learning methods often fail to generalize.

Developmental absence of maxillary lateral incisors in the Portuguese population [PDF]
European Journal of Orthodontics, 2005 The aim of this study was to evaluate the prevalence and clinical manifestation of developmental absence of maxillary permanent lateral incisors in the Portuguese population. The study group comprised 16 771 patients observed between 1993 and 2000 at the Faculty clinic. Two hundred and nineteen patients were found to have missing upper lateral incisors

Genetic and Morphological Variation in Hypodontia of Maxillary Lateral Incisors
Genes, 2023 (1) Background: Hypodontia has a multifactorial aetiology, in which genetic factors are a major component. Associated with this congenital absence, the formed teeth may show differences in size and shape, which may vary with the specific genetic variants and with the location of the missing teeth.
