Maxillary first premolar is most commonly a bi-rooted tooth, occasionally having three roots. It usually has two canals, but may rarely have three, which can easily be missed, demanding more attention during endodontic intervention. This paper reports this rarity of 3 roots and canals in maxillary premolar, highlighting the difficulties special care needed treatment. Careful investigation diagn...

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 ...

Evaluation of Microleakage Self-Adhesive Composite Resin in Pits and Fissures Extracted Premolar Teeth: An Vitro Study

conclusions the clinical success rates of endodontically treated premolars restored with fiber posts and direct composite restorations, direct composite restorations with cusp capping and simple direct composite restoration were perfect after one year of follow-up evaluation. background endodontically treated teeth need to be restored in a manner to provide protection for the remaining tooth st...

Correction of skeletal Class II malocclusion with camouflage orthodontic treatment generally requires the extraction maxillary first premolars to provide space for retraction incisors. Retraction incisors changes position and dimensions dental arch, which can cause in tongue posture affect upper airway. The purpose this study was determine relationship between premolar on airway malocclusion. T...

Introduction Based on previous researches, dental pulp stem cells (DPSCs) are easily accessible with limited morbidity after collection. Their embryonic origin, from neural crests, explains their multipotency. DPSCs are primarily derived from the pulp tissues of the teeth.Objective: This study was undertaken to isolate, culture, and characterize two different third molar and first premolar hum...

This report is a clinical case of a 7-year-old child who presented right impacted second primary mandibular molar. This tooth was positioned inferior to the second premolar successor and a supernumerary tooth superior to the second premolar. Clinical examination did not reveal systemic diseases ot trauma in the facial region. Treatment consisted of the extraction of the impacted second primary ...
