Finite Element Stress Analysis of Composite Polymerisation Shrinkage in Endodontically Treated Maxillary Central Incisors
Finite Element Polymerization Resin Composite
2009/4/2
Introduction: Resin composites are common materials used to restore anterior teeth following root canal therapy, but are accompanied with shrinkage during polymerization. The aim of this in vitro st...
Four fused incisors in the maxillary and mandibular primary dentitions
Fused tooth Maxillary and mandibular dentition Primary central incisor Primary lateral incisor
2008/11/12
Bilateral dental fusion in the primary dentition is a dental anomaly. However, bilateral fusion of maxillary and mandibular primary central and lateral incisors is very rare. The fused teeth were cons...
Severe cases of ectopically erupting maxillary canine with excessive mesial angulation
Ectopic eruption Eruption disturbance Impaction Maxillary canine Uneruption
2008/11/12
The aim of the present study was to examine retrospectively how best to treat severe cases of ectopically erupting maxillary canines with mesial angulation exceeding 50 degrees. From the ectopically e...
Root resorption of maxillary primary incisors in relation to position of successive permanent incisors by Micro-CT
Bony crypt Dry skulls of Indian children Maxillary primary incisors Micro-CT
2008/11/12
The aim of this study is to elucidate the root resorption of primary incisors in relation to the development of permanent incisors. We observed the maxillas of the dry skulls of Indian children, using...
Intentional replantation of maxillary molar affected by an intractable periapical abscess related to a radicular groove: A case report
Computerized tomography Fused roots Intentional replantation Radicular groove
2008/11/12
We presented a case of an intractable periapical abscess in the area of the maxillary first molar. The tooth had no evidences of dental caries, restoration, or fracture, and responded well to a pulp v...
