Introduction: Furcation perforation can have a negative impact on the prognosis of the affected tooth by compromising the attached apparatus. Hence these perforations require immediate repair. A variety of materials have been suggested for repair, of that MTA is the most promising material. The purpose of this study was to compare the ability of Gray and White MTA to seal furcation perforations using a dye extraction method under spectrophotometer.

Materials And Methods: A total of 60 permanent mandibular molars were randomly divided into four experimental groups of 15 samples each as follows: Group A: Perforation repaired with White MTA. Group B: Perforation repaired with Gray MTA. Group C: Perforation left unsealed (positive). Group D: without perforation (negative). Dye extraction was performed using full concentration nitric acid. Dye absorbance was measured at 550 nm using spectrophotometer. The data analyzed using one-way-Anova Ratio and Unpaired t-test showing statistically significance difference among the groups.

Result: It was seen that Group D samples without perforation showed least absorbance followed by Group A (perforation repaired with White MTA) and Group B (perforation repaired with Gray MTA). Group C (perforation left unsealed) showed highest absorbance.

Conclusion: The White and Gray Mineral Trioxide Aggregate performed similarly as a furcation perforation repair material. There was no significant difference between the Gray MTA and White MTA.

Management of a dentigerous cyst associated with inverted and fused mesiodens: a rare case report.

J Int Oral Health 2013 Aug 28;5(4):73-7. Epub 2013 Aug 28.

Inverted mesiodens is a disorder of Odontogenesis relatively characterized by an excess number of teeth in the premaxillary region, in between the central incisors and in an inverted direction. The etiology of inverted mesiodens is still unknown. The complications associated with inverted mesiodens include eruption disturbance of adjacent teeth, displacement & rotation of the central incisors, diastema, root resorption, abnormal occlusion, cyst formation or nasal eruption of the mesiodens. Early detection and timely surgical intervention of inverted mesiodens is crucial to prevent unwanted consequences. Dentigerous cysts are developmental cysts of odontogenic origin, which are found to surround the crown of unerupted/erupting teeth, odontomas or even supernumerary teeth. Dentigerous cysts' involving an inverted mesiodens is a rare occurrence with only few cases reported.This article reports a rare and unusual case of a dentigerous cyst of the anterior maxilla involving an inverted and fused mesiodens.

Traumatic injuries of teeth involve varying degrees of damage to the supporting soft tissues or the teeth itself. A very common injury to the permanent dentition affecting children and adolescents during their growing years is the anterior crown fracture. Recent developments in restorative material, placement techniques, preparation designs, and an adhesive protocol allow clinicians to predictably restore fractured teeth. With the advent of adhesive dentistry the process of fragment reattachment has become simplifed and more reliable. This procedure provides an improved function, is relatively faster to perform and at the same time provides long lasting esthetics. This paper discusses various innovative techniques of fracture reattachment depending on the complexity of the case.
