Early diagnosis of agenesis of the mandibular second premolar (P2) enhances management of the dental arch in the growing child. The aim of this study was to explore the relationship in the development of the mandibular first molar (M1) and first premolar (P1) at early stages of P2 (second premolar). Specifically, we ask if the likelihood of P2 agenesis can be predicted from adjacent developing ...

The upper second premolars are often known to be interfered with the normal development of their roots by the periapical disturbance of the precursor and its adjacent teeth and, in some cases, by the position of floor of the maxillary sinus. This phenomenon called dilaceration is usually characterized by a crease or bend at the junction of the crown and root [1]. In our 10-year consecutive surv...

Distal displacement of the tooth germ mandibular second premolar (MnP2) leads to its impaction and obturation eruption path first molar delaying eruption. The present case report describes treatment 2 cases guidance for distally displaced developing MnP2 that caused delayed molar. Intentional extraction primary predecessor results in mesial shift MnP2. However, unfavorable distal ectopic after ...
