Spectrophotometric measurements and its correlation to human eye color perception. Influence of white/black vs. Cuspal/non cuspal backgrounds on tooth color assessment

BACKGROUND: The aim of this in vivo study was to compare
spectrophotometric backgrounds - white (WB) with
cuspal (C), black (BB) with non cuspal (NC) - in order to
determine if the oral natural conditions could be used as reliable
backgrounds instead of the traditional black and/or white
for in vivo color matching.
Methods: Spectrophotometric measurements were performed
on ninety-three upper right permanent central incisor.
Among inclusion criteria were A1, A2, A3 (Vita Classical

Dental erosion in patients affected by eating disorders: a preliminary study

BACKGRO UND: Dental erosion, which is the irreversible
loss of hard tissues of the tooth due to a chemical process on
the dental surface, sees the presence of acids as a fundamental
prerequisite: erosive wear is complex and depends on the
interaction of biological, chemical and behavioral disorders,
making it a multi-factor etiology injury. This preliminary
study aims to show the correlations between Eating Disorders
and the onset of dental erosion, from the point of view of clinical

Evaluation of the application of italian national guidelines for prevention and management of dental injuries in developmental age

Background: The objective of this study is to evaluate the application of National guidelines for prevention and clinical management of traumatic dental injuries (NGPCMTDI) in developmental age published by the Italian Ministry of Health. Methods: In the present retrospective and multicenter study, 246 patients who underwent dental injury were selected to assess the management of the traumatic event compiled with the protocol provided by the National guidelines. Each health worker involved completed a form related to the dental injury in order to standardize the collected data.

Orthodontic white spot lesions (WSLs) can affect patients’ aesthetic satisfaction? A spectrophotometric approach

The aim of this in vivo study was to evaluate the colourimetric
changes between sound enamel and post orthodontic WSLs and to
correlate these findings with human eye colour perception threshold
using spectrophotometry. Experimental approach Seventy-six
permanent teeth with post orthodontic WSLs in 12–16 years old
patients were evaluated in this in vivo study at “Sapienza”University
of Rome. The spectrophotometric differences in colour (ΔL*, Δa*,
Δb*; Color Difference ΔE00; Whiteness Index ΔWIO) between

Relationship between upper lateral incisors anomalies and palatal displaced canine: a case-control retrospective study

Background: An observational case-control study was designed to retrospectively assess the association among sex, skeletal and dental variables and the and the palatal maxillary canine impaction. Methods: The STROBE guidelines were followed. The records of 2195 subjects were analyzed. The data records of subjects with palatally displaced canine (PDC) were compared with the data of randomly selected subjects without PDC. Descriptive statistics, logistic regression model and χ2 test were used.
