Long-term survival of retained deciduous mandibular second molars and maxillary canine incorporated into final occlusion
Orthodontic treatment of a complex case that involves retained deciduous mandibular second molars with missing permanent successors is challenging. Usually, congenitally missing teeth are manifested with other dental anomalies that further complicate orthodontic treatment, such as retained deciduous teeth, impactions, transpositions and peg-shaped lateral incisors. Even though the long term pro...
متن کاملTotal Impaction of Deciduous Maxillary Molars: Two Case Reports
Background: Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membrane, trauma, injury of the periodontal ligament, precocious eruption of the first permanent molar, defective eruptive force, or a combination of ...

متن کاملMorphometric analysis of developing crowns of maxillary primary second molars and permanent first molars in humans.
The purpose of this study was firstly to characterize the changes occurring in size and form of the mineralizing maxillary second primary molar and first permanent molar crowns, and secondly to determine if similar changes in size and form characterize enamel apposition in the crowns of these teeth. Twenty-five primary second molars and 20 maxillary permanent first molars at various stages of d...
متن کاملAnalysis of pulp chamber of primary maxillary second molars using 3D micro-CT system: an in vitro study.
AIM The aim of this study was to determine the positional relationship between the crown contour and the pulp chamber as well as the morphological characteristics of the pulp chamber using micro-CT in order to plan, in restorations of deciduous maxillary second molars, reconstructions with a volumetric rendering programme. MATERIALS AND METHODS STUDY DESIGN In total 16 deciduous maxillary ...
