The mean peak value of fluorescence in the carious area was recorded and teeth were divided in enamel caries, dentin caries and sound dental structure. After fluorescence readings, Raman spectroscopy was carried out on the same sites. The results showed significant difference (ANOVA, p<0.05) between the fluorescence readings for enamel (16.4 ± 2.3) and dentin (57.6 ± 23.7) on carious teeth. Raman peaks of enamel and dentin revealed that ∼575 and ∼960 cm−1 peaks were more intense in enamel caries. There was significant negative correlation (p<0.05) between the ∼575 and ∼960 cm−1 peaks and dentin caries. It may be concluded that the higher the fluorescence detected by Diagnodent the lower the peaks of phosphate apatite and fluoridated apatite. As the early diagnosis of caries is directly related to the identification of changes in the inorganic tooth components, Raman spectroscopy was more sensitive to variations of these components than Diagnodent.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-11-12T12:20:07Z No. of bitstreams: 1 Fabíola Bastos de Carvalho.pdf: 288796 bytes, checksum: 051f7d8a8f461caf77dc6164edf777e0 (MD5)Approved for entry into archive by Delba Rosa (delba@ufba.br) on 2014-11-12T14:39:56Z (GMT) No. of bitstreams: 1 Fabíola Bastos de Carvalho.pdf: 288796 bytes, checksum: 051f7d8a8f461caf77dc6164edf777e0 (MD5)Made available in DSpace on 2014-11-12T14:39:56Z (GMT).
