The risk of healing complications in primary teeth with concussion or subluxation injury-A retrospective cohort study.

Background/aim: Traumatic dental injuries in the primary dentition occur frequently. Long-term complications may potentially cause damage to the permanent successor. The aim of this study was to report the risk of pulp necrosis (PN), pulp canal obliteration (PCO), repair-related resorption (RRR), infection-related resorption (IRR), ankylosis-related resorption (ARR), and premature tooth loss (PTL) in primary teeth following concussion and subluxation injuries, and to identify possible risk factors for PN, PCO, and PTL following subluxation.

Maxillary Sinus Impaction of a Core Carrier Causing Sustained Apical Periodontitis, Sinusitis, and Nasal Stenosis: A 3-year Follow-up.

Introduction: The aim was to present a case report of a full-length extrusion of an obturator's core carrier into the maxillary sinus, causing clinical symptoms from the nose region with differential diagnostics aspects, which, in turn, led to several surgical treatments of the nostrils before diagnosis and correct endodontic retreatment of a maxillary right first molar. A 36-year-old man presented in 2012 with complaints from the right nostril region. Medical treatment with antibiotics and surgical procedures because of nasal stenosis resulted only in partial improvement.
