Objective:
Double antibiotic paste is a root canal medicament used in regenerative endodontics and its long-term exposure to dental hard tissues was shown to reduce its mechanical properties. The amoxicillin-clavulanate paste is a medicament effective against endodontic pathogens and is effective in endodontic regeneration. Its effect on radicular dentine is yet to be investigated. The purpose of this study is to investigate and compare the effects of double antibiotic paste and amoxicillin-clavulanate paste on the microhardness of radicular dentine.
Materials and Methods:
The root canal of 45 premolars was mechanically prepared and divided into three groups for the placement of intracanal medicament: Group 1 (
n
= 15) double antibiotic paste, Group 2 (
n
= 15) amoxicillin-clavulanate paste, and Group 3 control group (
n
= 15). All the specimens were subject to microhardness testing at 500 and 1000 microns depth for 1 week, 1 month, and 3 months and analyzed.
Results:
There is no significant reduction in microhardness of radicular dentin at 1 week on all the three groups. At 1 month and 3 month period, the amoxicillin-clavulanate paste is found to have no significant effect on dentin microhardness when compared to double antibiotic paste.
Conclusion:
The use of amoxicillin-clavulanate paste as an intracanal medicament does not cause significant weakening of dentin even after its long-term use.
Odontomas behave more like developmental abnormalities (hamartomas) than true neoplasms. Odontomas are developmental anomalies resulting from the growth of completely differentiated epithelial and mesenchymal cells that give rise to ameloblast and odontoblast. Odontomas are classified as complex odontoma and compound odontomas. The purpose of the article is to enumerate the diagnostic criteria for odontomas.

Coronal fractures of the anterior teeth are a common form of dental trauma that mainly affects children and adolescents. Various treatment modalities have been practiced in the past, but reattachment of fractured fragment is considered to be the most conservative, natural, and esthetic approach. The restoration of natural teeth form, color, and alignment in these patients creates a positive social and emotional response in such patients. This paper reports on conservative management of the fracture of maxillary anterior teeth using two different approaches, namely, one with tooth fragment reattachment and other of recontouring with composite resin.
