[Ab] Abstract:For patients with a single discolored tooth who desire to have it lightened, a thorough examination and radiographic analysis need to be performed prior to initiating any bleaching treatment so that the cause of the discoloration can be determined. Underlying pathology, such as internal resorption, is often asymptomatic and difficult to diagnose and if left untreated could result in tooth loss. This article describes a case of a patient with a discolored maxillary central incisor resulting from internal resorption and the subsequent endodontic and bleaching therapy performed to resolve the pathology and achieve an acceptable esthetic result.

[Ab] Abstract:Occlusal discoloration due to staining frequently occurs on the pits and fissures of teeth. Noncariogenic discoloration (non-CD) refers to the attachment of staining chromogens to sound surfaces, whereas cariogenic discoloration (CD) represents the discoloration of porous structures due to bacterial metabolites and mineral loss from the enamel surface. This study evaluated whether it is possible to distinguish between non-CD and CD on stained occlusal surfaces with fluorescence assessed by the quantitative light-induced fluorescence (QLF) technology. Sixty-two extracted human permanent teeth with suspected discolorations on the pit and fissure were examined. The maximum values of fluorescence loss (ΔFmax) and red fluorescence gain (ΔRmax) were calculated using QLF images. Using histology as the gold standard, it was found that 12 teeth were sound (non-CD), while 50 teeth had enamel and dentine caries (CD). The validity tests at the enamel histological caries level, ΔRmax (ρ = 0.80) were strongly correlated with the histology (P < 0.001). At the optimum threshold (105.0) of ΔRmax, it showed high levels of sensitivity and specificity (0.96 and 0.83, respectively). Therefore, QLF can be used to distinguish non-CD from CD on occlusal surfaces using red fluorescence values with high validity.

[Ab] Abstract:FOCUS QUESTION: What is the efficacy of a chlorhexidine (CHX) mouthwash (MW) containing sodium fluoride (NaF) compared to a CHX - MW alone on the parameters of plaque, gingivitis and discoloration? MATERIAL AND METHODS: MEDLINE-PubMed, Cochrane-CENTRAL, and EMBASE were searched for papers from inception to December 2017. The inclusion criteria were (randomized) controlled clinical trials conducted in human subjects with good general health and without removable prosthesis. Papers evaluating the effect of a MW containing CHX + NaF compared to a CHX alone were included. From the eligible studies, data were extracted, a descriptive analysis was performed and a meta-analysis when feasible. RESULTS: Independent screening of 412 unique papers resulted in 9 eligible publications presenting 10 clinical trials comparing the effect of CHX + NaF to CHX - MW and provided 13 comparisons. Five evaluated the MW as an adjunct to brushing and 8 were non-brushing comparisons of which 4 used an experimental gingivitis model. No significant difference was observed for plaque score reduction in the brushing studies the end scores (diffM; -0.04, P = .36; 95%CI: [-0.13, 0.05]) nor the differences (diffM; 0.11, P = .33; 95%CI: [-0.12, 0.24]). In the descriptive analysis, none of the experiments demonstrated a statistical significant difference regarding Gingival Index (GI), Bleeding Score and Discoloration Scores. For the GI, a meta-analysis of the difference of Means was not significant when included experimental gingivitis model studies end scores (0.01, P = .78; 95%CI: [-0.08, 0.11]) and the difference (0.01, P = .81; 9 5%CI: [-0.08, 0.10]) either for the end scores of brushing studies (diffM; -0.01, P = .82; 95%CI: [-0.10, 0.08]). CONCLUSION: From this study, it can be concluded that NaF and CHX may be present in the same MW without reducing CHX efficacy with respect to plaque and gingivitis scores. Moreover, no difference in the development of tooth discoloration was observed.

[Ab] Abstract:OBJECTIVE: Three kinds of zirconia specimens were made respectively by milling of the prisintered blocks and by three dimensional (3D) gel deposition for in vitro evaluation of their optical translucency under three different thicknesses and their color masking effect on discolored teeth. The study aims for establishing the principle for guiding the materials selection in clinical practice. METHODS: Ninety A2-colored zirconia disc specimens with diameter of 14 mm were prepared and were divided into three groups (n=30). (1) Group CZ, by milling of the presintered blanks; (2) Group NZW, by 3D gel deposition, without a color masking opaque inner layer; (3) Group NZY, by 3D gel deposition, with a color masking opaque inner layer. Furthermore, each group was divided into three sub-groups (n=10) according to the sample thickness, i.e., 0.6, 1.0 and 1.5 mm, respectively. The maxillary anterior teeth with severe discoloration, extracted owing to periodontal disease, were collected and embedded. By gentle gridding and polishing a plane, larger than 6 mm2×6 mm , was generated on the labial surface of each tooth. Chromatic values(CIE1976-L a b ) of the zirconia samples in the nine sub-groups were measured by the spectrophotometer Crystaleye in front of the black or white background in a cassette, and the translucency parameter (TP) values were calculated for each sample. Thereafter the zirconia specimens were bonded onto the labial surface of the polished teeth for measuring the chromatic values, using the chromatic value of the medium 1/3 of the standardized Vita A2 as a control. The color aberration ΔE between each zirconia specimen and the control value was calculated, respectively. The results were statistically analyzed by One-way ANOVA and Bonferroni. RESULTS: (1) The optical transparency of the three kinds of zirconia disc specimens with the thickness of 0.6, 1.0 and 1.5 mm was 14.09, 12.31 and 10.45 for group CZ; 19.84, 16.54 and 12.44 for group NZW;14.81, 13.16 and 11.92 for group NZY. In each group, the degree of optical transparency of the specimens showed a clear tendency as in the sub-group 0.6 mm >1.0 mm >1.5 mm. The TP value of the specimens in the three groups with the same thickness showed a tendency of the group NZW >group NZY >group CZ. (2) After bonding onto the polished labial surface of the teeth, the color aberration ΔE of the specimens with the thickness of 0.6, 1.0 and 1.5 mm was calculated to be 10.77, 9.94 and 8.50 for group CZ; 6.84, 5.89 and 5.29 for group NZW; 4.16, 3.92 and 3.67 for group NZY. In each group, the color aberration of the specimens showed a clear tendency as in the sub-group 0.6 mm >1.0 mm >1.5 mm; the color aberration of the three groups with the same thickness was in the order of the group CZ >group NZW >group NZY. CONCLUSION: In all the specimen groups with a fixed specimen thickness, the optical translucency of the specimen was the highest in group NZW made by 3D gel deposition, and the best color masking effect was obtained in specimens with a color masking opaque inner layer in group NZY, where a thickness of 0.6 mm was sufficient enough for obtaining the ideal color masking effect.

[Ab] Abstract:INTRODUCTION: This study aimed to compare the success rates of direct pulp capping (DPC) by using either ProRoot Mineral Trioxide Aggregate (MTA) or Biodentine in the cariously exposed permanent teeth of 6- to 18-year-old patients. Gray discoloration was also evaluated. METHODS: Fifty-nine cariously exposed permanent teeth, including teeth with diagnosis of normal pulp, reversible pulpitis, or irreversible pulpitis, early periapical involvement, and exposure size of up to 2.5 mm, were included. Each patient with only 1 cariously exposed tooth was randomly allocated to DPC with either ProRoot MTA (n = 30) or Biodentine (n = 29). Patients were recalled every 6 months. Clinical and radiographic examinations were used to determine success. RESULTS: Fifty-five patients (mean age, 10 ± 2 years), 27 treated with ProRoot MTA and 28 with Biodentine, were included in the analysis. At mean follow-up of 18.9 ± 12.9 months, the success rate was 92.6% with ProRoot MTA and 96.4% with Biodentine (P > .05; difference, 4%; 95% confidence interval [CI], -8% to 16%). Biodentine was non-inferior to ProRoot MTA. Failures were distributed equally in all categories of pulpal diagnosis and occurred in teeth with no periapical involvement and small exposures (0.5 mm). The survival probabilities of DPC with ProRoot MTA and Biodentine were 0.92 (95% CI, 0.73-0.98) and 0.96 (95% CI, 0.80-0.99). No significant difference was observed between them (P > .05). Gray discoloration was observed only with ProRoot MTA (55%). CONCLUSIONS: Biodentine was non-inferior to ProRoot MTA when used as a DPC material for cariously exposed permanent teeth of 6- to 18-year-old patients. However, Biodentine did not cause any gray discoloration in this study.

[Ab] Abstract:BACKGROUND: To investigate the association between critical and communicative oral health literacy (OHL) and oral health outcomes (status, oral health-related quality of life and practices) in adults. METHODS: This cross-sectional study examined a household probability sample of 248 adults, representing 149,635 residents (20-64 years old) in Piracicaba-SP, Brazil. Clinical oral health and socioeconomic and demographic data, as well as data on oral health-related quality of life (OHIP-14) and health practices were collected. The oral examinations were carried out in the participants' homes, using the World Health Organization criteria for oral diseases. The critical and communicative OHL instrument was the primary independent variable, and it was measured using five Likert items that were dichotomized as 'high' ('agree' and 'strongly agree' responses for the 5 items) and 'low' OHL. Binary and multinomial logistic regressions were performed on each outcome (oral health status and practices), controlling for age, sex and socioeconomic status (SES). RESULTS: Approximately 71.5% presented low OHL. When adjusted for age and sex (first model) low OHL was associated with untreated caries (Odds Ratio = 1.92, 95% Confidence Interval = 1.07-3.45), tooth brushing <3 times a day (OR = 2.00, 1.11-3.62) and irregular tooth flossing (OR = 2.17, 1.24-3.80). After SES inclusion in the first model, significant associations were found for low OHL when the outcomes were: presence of biofilm (OR = 1.83, 1.08-3.33), dental care for emergency only (OR = 2.24, 1.24-4.04) and prevalence of oral health impact on quality of life (OR = 2.06, 1.15-3.69). CONCLUSION: Adjusting for age, sex and SES, OHL is related to a risk factor (biofilm) and a consequence of poor oral health (emergency dental visits) and can interfere with the impact of oral diseases on quality of life. As low OHL can be modified, the results support oral health promotion strategies directed at improving critical and communicative oral health literacy in adult populations.

[Ab] Abstract:The aim of this study was to compare customized zirconia and titanium abutments with respect to survival rates and technical, biologic, and esthetic outcomes. A total of 28 patients with single implants were randomly assigned to 12 customized zirconia (test, AC) and 16 customized titanium (control, MC) abutments. Technical, biologic, and esthetic outcomes were assessed after a mean follow-up time of 18 months. No biologic complications were observed, and no statistical difference for the bone-to-implant distance was found at 18 months (AC -0.05 ± 0.51 mm vs MC -0.28 ± 0.77 mm; P = .40). A similar discoloration of the peri-implant mucosa was observed (ΔE 9.6 ± 5.4, ΔE 7.6 ± 5.3; P = .46). The mean papilla score values evaluation presented no statistically significant differences between the test and control groups (AC 2.07 ± 0.94, MC 1.96 ± 0.84). At 18 months, reconstructions based on zirconia and titanium abutments exhibited similar survival rates and similar clinical outcomes.
