We designed an arrayed-waveguide grating spectrometer for the detection of early dental caries in teeth through polarized Raman spectroscopy. Measurement results on extracted human teeth demonstrate the feasibility of the approach. (Abstract) Keywords-component; Raman spectroscopy; integrated optics;

Fracture of anterior teeth due to trauma is the most frequent type of injury affecting permanent dentition. Despite the availability of a wide range of restorative materials, none could match the properties of natural tooth structure like translucency, wear resistance, and color stability. Hence fragment re-attachment is an excellent method of restoring fractured teeth. When the fractured fragm...

PURPOSE The purpose of this study was to investigate the principal reason for primary tooth extraction and the tooth type most frequently extracted in children aged 3-13 years. METHODS The patients selected for this retrospective study were identified by analyzing dental records of children receiving treatment at Franciscan Children's Hospital & Rehabilitation Center, Boston, MA (FCH & RC). I...

Aim: To evaluate the effect of storage media and autoclaving on shear bond strength of composite to enamel. Materials and Methods: 100 human premolars were randomly divided into ten groups of ten as follows: C: freshly extracted teeth. A: Autoclaved freshly extracted teeth. CH-6: 6 month storage in 0.5 % chloramine T. CA-6: 6 month storage in 0.5 % chloramine T + autoclaving. T-6: 6 month stora...

Fusion of teeth is the union of two or more tooth germs, which are usually separated. Depending upon the stage of odontogenesis, it can be complete or incomplete. The present case describes fusion between the maxillary primary right central and lateral incisor with a supernumerary tooth. Clinical and radiographic examination revealed the presence of fused triple teeth. The fused teeth were extr...
