Factors Involved in the Perception of Enamel Dyschromic Lesions-A Questionnaire-Based Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19020900. [PMID: 35055723 PMCID: PMC8775837 DOI: 10.3390/ijerph19020900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 01/11/2022] [Accepted: 01/12/2022] [Indexed: 11/24/2022]
Abstract
Dyschromic lesions (DLs) of tooth enamel are common disorders, with multiple etiologies and various clinical forms, that raise public health concerns. This study aimed to determine the factors that influence the perception of DLs and to assess the perceived need for dental treatment in various clinical cases. A paper-based questionnaire with attached images of frontal teeth exhibiting different DLs was distributed to patients, dental students, and dentists. A total of 383 volunteers participated in this study, and their answers were statistically described and analyzed. This study found that in cases with multiple, well-demarcated areas of opacities associated with diffuse opacities on neighboring teeth, most respondents noticed and reported only the most severe lesions, disregarding the minor ones. The contrast of the lesion with the color of the substrate influenced the overall perception and a significant correlation between these two variables was found. However, the color of the DLs did not significantly impact the overall perception of the lesions. A higher overall perception of DLs was significantly correlated with a favorable opinion regarding the need for treatment. Furthermore, gender and medical background were significantly associated with the overall perception of DLs.

Pan Z, Que K, Liu J, Sun G, Chen Y, Wang L, Liu Y, Wu J, Lou Y, Zhao M. Effects of at-home bleaching and resin infiltration treatments on the aesthetic and psychological status of patients with dental fluorosis: A prospective study. J Dent 2019; 91:103228. [PMID: 31704387 DOI: 10.1016/j.jdent.2019.103228] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 11/02/2019] [Accepted: 11/04/2019] [Indexed: 10/25/2022] Open
Abstract
OBJECTIVE This study aims to evaluate the effect of the combination approach of at-home bleaching (HB) and resin infiltration (RI) techniques on different severity degrees of dental fluorosis (DF) and further analyze the psychological changes caused by HB and RI in patients. METHOD Twenty-two patients (4 males, 18 females, 27.8 ± 1.6 yrs) with 186 fluorotic teeth were included in this study and classified into mild (N = 56), moderate (N = 100) and severe (N = 30) DF groups according to the Dean's index. The treatment effects on patients with DF were assessed by questionnaires including the changes in patients' subjective evaluation of their teeth and psychological status before and after treatments. Standardized digital photographs were taken at each time point of the treatment process, including baseline (T1), after bleaching (T2), immediately after RI treatment (T3) and more than six months after RI treatment (T4). The color alterations (ΔE) between the fluorotic (F2) and the surrounding relatively sound areas (F1) were analyzed. RESULTS Bad tooth appearance caused 13.64% of patients often depressed, frustrated, or disappointed, whereas 72.72% occasionally had these feelings. After treatment, the satisfaction of DF patients regarding tooth appearance increased from 0% (satisfied) to 58.82% (satisfied) and 23.53% (very satisfied). Moreover, these treatments improved all patients' confidence in smiling, laughing and showing their teeth. The percentage of fluorotic teeth with ΔE values more than 3.0 and 3.7 units decreased gradually from T1 stage to T3 stage in mild and moderate DF groups (p < 0.05), whereas the ΔE value in T3 stage was significantly lower than that of T2 stage in severe DF group (p < 0.05). In T4 stage, no significant difference was observed in the ΔE values between T4 and T3 stages (p > 0.05). CONCLUSION This study shows the obvious positive aesthetic effect of HB and RI treatment on different severity degrees of DF and the great improvements in psychological discomforts. CLINICAL SIGNIFICANCE The combination treatment of RI and low concentration HB gel improves the aesthetics of DF and may have a stable effect after 6-months follow-up, suggesting that this approach is a valuable clinical choice for dentists to treat DF.

[PMID: 30159081 PMCID: PMC6108811 DOI: 10.3889/oamjms.2018.304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 07/26/2018] [Accepted: 07/28/2018] [Indexed: 11/09/2022] Open
Abstract
AIMS: This study aimed to compare the participant’s perceptions about their peers’ dento-facial condition with different incisal appearances (intact, discoloured, fractured, and avulsed incisors). MATERIALS AND METHODS: A cross-sectional study was conducted among schoolchildren of both primary (8-11 years) and secondary (12-14 years) levels. Each participant was asked to judge photographs with one intact and three digitally modified central incisors giving the appearance of a traumatised tooth. Data on perceptions were collected for each condition using 12 attributes (8 positive and 4 negative; scored on a 4 point Likert scale). The positive, negative and total attribute scores were analysed separately by unpaired Student’s t-test. Repeated Measures ANOVA and Bonferroni post hoc analysis was also used. RESULTS: A group of 587 children participated in the study. The perception for intact and traumatised incisors about demographic factors is well appreciated. Among the gender delineation, girls showed a significant difference in judgment between discoloured and fractured incisors. In comparison to intact incisors, positive and total attributable scores were found to be significantly higher (P < 0.001), whereas negative attribute scores were significantly lower (P < 0.001) for traumatised incisors. Pairwise comparison showed high significance (p <0.001) between the intact and traumatised incisor conditions. CONCLUSION: The results demonstrated that visible dental trauma influenced the psychosocial judgment given by children towards their peers. This judgment would, in turn, affect their level of acceptance towards such appearances. Therefore, these conditions ought to be redressed as swiftly as possible. CLINICAL SIGNIFICANCE: The primary purpose of this study was to highlight the psychosocial perceptions of children in judging their peers, regarding not only attractiveness but also intelligence, friendliness, confidence, outgoing nature, etc.

Abstract
Aims and Objectives: Colored and deformed fluorotic teeth may affect the quality of life (QOL). The present study, therefore, evaluates the effect of dental fluorosis on the QOL of female high school and precollege students of Behbahan district in 2014. Materials and Methods: One hundred 15–18-year-old female students with dental fluorosis were selected from the high schools of Behbahan district by random cluster sampling technique. Dental fluorosis was measured clinically using Dean's index after analyzing the drinking water of the affected district. The effect of dental fluorosis on the QOL was then evaluated through a questionnaire. The data from Dean's index, condition-specific oral impact on daily performance (CS-OIDP) questionnaire, and the mean score of QOL questionnaire were analyzed in SPSS version 20 using Pearson's and Spearman's correlation analyses (α = 0.05). Results: The mean values of age and the QOL regarding appearance were 16.5 years and 61.5 ± 20.8 from 100, respectively. Spearman's correlation showed a positive correlation between CS-OIDP total score and the severity of fluorosis (P = 0.0001, r = 0.342). Spearman's correlation also showed a negative correlation between the QOL and the severity of fluorosis (P < 0.001, r = −0.496) so that by increasing the severity of fluorosis, the QOL was decreasing. Conclusions: Increasing the severity of fluorosis is associated with increasing the dissatisfaction and decreasing the QOL.

Abstract
AIMS This study investigated the effectiveness of laser-assisted in-office bleaching and home-bleaching in sound and demineralized enamel. MATERIALS AND METHODS The sample consisted of 120 freshly-extracted bovine incisors. Half of the specimens were stored in a demineralizing solution to induce white spot lesions. Following exposure to a tea solution for 7.5 days, the specimens were randomly assigned to 4 groups of 30 according to the type of enamel and the bleaching procedure employed. Groups 1 and 2 consisted of demineralized teeth subjected to in-office bleaching and home bleaching, whereas in groups 3 and 4, sound teeth were subjected to in-office and home bleaching, respectively. A diode laser (810 nm, 2 W, continuous wave, four times for 15 seconds each) was employed for assisting the in-office process. The color of the specimens was measured before (T1) and after (T2) staining and during (T3) and after (T4) the bleaching procedures using a spectrophotometer. The color change (ΔE) between different treatments stages was compared among the groups. RESULTS There were significant differences in the color change between T2 and T3 (ΔE T2-T3) and T2 and T4 (ΔE T2-T4) stages among the study groups (p<0.05). Pairwise comparison by Duncan test revealed that both ΔET2-T3 and ΔET2-T4 were significantly greater in demineralized teeth submitted to laser-assisted in-office bleaching (group 1) as compared to the other groups (P< 0.05). CONCLUSION Laser-assisted in-office bleaching could provide faster and greater whitening effect than home bleaching on stained demineralized enamel, but both procedures produced comparable results on sound teeth.

Abstract
Background To assess the ability of fluorescence imaging to detect a dose response relationship between fluorosis severity and different levels of fluoride in water supplies compared to remote photographic scoring in selected populations participating in an observational, epidemiological survey in Chiang Mai, Thailand. Methods Subjects were male and female lifetime residents aged 8-13 years. For each child the fluoride content of cooking water samples (CWS) was assessed to create categorical intervals of water fluoride concentration. Fluorescence images were taken of the maxillary central incisors and analyzed for dental fluorosis using two different software techniques. Output metrics for the fluorescence imaging techniques were compared to TF scores from blinded photographic scores obtained from the survey. Results Data from 553 subjects were available. Both software analysis techniques demonstrated significant correlations with the photographic scores. The metrics for area effected by fluorosis and the overall fluorescence loss had the strongest association with the photographic TF score (Spearman’s rho 0.664 and 0.652 respectively). Both software techniques performed well for comparison of repeat fluorescence images with ICC values of 0.95 and 0.85 respectively. Conclusions This study supports the potential use of fluorescence imaging for the objective quantification of dental fluorosis. Fluorescence imaging was able to discriminate between populations with different fluoride exposures on a comparable level to remote photographic scoring with acceptable levels of repeatability.

Abstract
BACKGROUND The use of fluorides for caries prevention is well established but is linked with an increased risk of dental fluorosis, some of which may be considered to be aesthetically objectionable. Patient opinion should be considered when determining impact on aesthetics. The aim of this study was to assess participant rating of dental aesthetics (from photographic images) of 11 to 13 year olds participating in an epidemiological caries and fluorosis survey in a fluoridated and a non-fluoridated community in Northern England. METHODS Consented participants were invited to rank in order of preference (appearance) a collage of 10 computer generated images on a touch-screen laptop. The images comprised an assortment of presentations of teeth that included white teeth, a spectrum of developmental defects of enamel and dental caries. Data were captured directly and exported into SPSS for analysis. RESULTS Data were available for 1553 participants. In general, there were no significant differences in the rank positions between the fluoridated and non-fluoridated communities, with the exception of teeth with caries and teeth with large demarcated opacities. Very white teeth had the highest rating in both localities. Overall, there was a trend for teeth with fluorosis to be ranked more favourably in the fluoridated community; for TF 1 and TF 2 this preference was significant (p < 0.001). CONCLUSIONS The results of this study suggest teeth that are uniformly very white have the highest preference. The rankings suggest teeth with a fluorosis score of TF 1 may not be considered aesthetically objectionable to this population and age group. The image depicting a tooth with caries and the image with large demarcated opacities were deemed to be the least favoured. Participant preference of images depicting fluorosis falls with increasing severity of fluorosis.

Abstract
There is much that we know about fluoride as it relates to human health in general and dental health in particular. Some of the information that is known concerning water fluoridation and dental fluorosis is listed. What we do not know about fluoride is discussed in more detail, namely the efficacy of lower levels of fluoride in drinking water, the effect of discontinuing fluoride in drinking water in the absence of additional preventive measures, the prevalence of fluorosis and whether or not this presents a cosmetic problem. Other issues discussed include the actual amount of fluoride ingested from all sources, whether low-fluoride dentifrices are as efficacious as conventional dentifrices in caries protection and reducing enamel fluorosis, the role of socioeconomic factors in determining caries prevalence, and the effects of bottled water use on caries prevalence in fluoridated communities.

Abstract
OBJECTIVES To ascertain what proportion of dental hygienists and dentists in Indiana, United States, support the application of fluoride varnish in medical offices, and to determine if support differed by dental provider characteristics, practice characteristics, a limited assessment of knowledge about fluoride, or use of fluoride. METHODS Practicing dental hygienists and dentists in 2005 were asked to fill out a mail questionnaire. Logistic regression models tested the association of independent variables with support for medical providers applying varnish. RESULTS Response rates were 36% (dental hygienists) and 37% (dentists); median year of graduation was 1988 and 1981. Sixty-six percent of respondents were in solo practices, 82% of dentists in general practice, 5% in dental pediatrics, and 13% were other specialists. While 51.2% of dental professionals agreed that medical practices could apply fluoride varnish, 29% responded "none" should be allowed, and 19% were undecided. In the multivariable logistic regression for support of medical practices applying fluoride versus not supporting it, three practice characteristics and two measures of fluoride use were significant. Provider characteristics and a limited assessment about knowledge about fluoride were not significant. CONCLUSIONS Half of dental professionals felt that it was appropriate for medical providers to apply fluoride varnish; pediatric dental professionals were less supportive. A few dental practice characteristics were associated with acceptance of the use of fluoride varnish by medical care providers: targeting messages to dental hygienists and those with practices in mixed rural-urban areas may be a useful approach to garner greater support for this medical/dental partnership.

Abstract
UNLABELLED Aesthetic perceptions and oral health-related quality of life concerning dental fluorosis have been assessed in several studies during the past two decades. However, no comprehensive review article summarizing the studies investigating this issue has been published. OBJECTIVE To assess the relationships between perceptions of dental appearance/oral health-related quality of life (OHRQoL) and dental fluorosis. METHODS The PubMed database was searched using the Medical Subject Headings (MeSH) for English-language studies from 1985 to March 2009. Thirty-five articles qualified for inclusion and then were classified into three categories based on the type of study approach: (i) respondent review of photographs and assessment concerning satisfaction/acceptance, (ii) respondent assessment of study subject's teeth concerning satisfaction/acceptance, and (iii) respondent assessments of the psychosocial/OHRQoL impact. RESULTS There were varied results from earlier studies focused on satisfaction/acceptance of very mild to mild fluorosis. More recent studies with methodological improvements to assess impact on quality of life clearly showed that mild fluorosis was not a concern. Furthermore, mild fluorosis was sometimes associated with improved OHRQoL. Severe fluorosis was consistently reported to have negative effects on OHRQoL. CONCLUSION Because dental fluorosis in the United States and other nations without high levels of naturally-occurring fluoride is mild or very mild, with little impact on OHRQoL, dental professionals should emphasize the appropriate use of fluorides for caries prevention and preventing moderate/severe fluorosis.

Abstract
This study evaluated the effectiveness of two microabrasion products for the removal of enamel fluorosis stains. Using a split-mouth study design, two operators used PREMA (PM) and Opalustre (OP) to remove fluorosis-like stains from 36 subjects (10-12 years old). Both products were rubbed onto the surface of the affected teeth for 30 seconds. This procedure was repeated five times during each clinical appointment. A maximum of three clinical appointments were scheduled. The subjects and/or their parents were questioned about their satisfaction with the treatment. Two blinded evaluators appraised both sides of the mouth using a visual scale system. The data were analyzed by Friedman repeated measures ANOVA and Wilcoxon test. The majority of the subjects (approximately 97%) reported satisfaction at the end of the treatment (p = 0.0001). A significant improvement in appearance was detected after the second clinical appointment when using PREMA and Opalustre (p < 0.002). After the first clinical appointment, OP showed a statistically higher mean rating for improvement in appearance (3.4 +/- 0.7) than PM (2.4 +/- 0.5) (p = 0.002).

Abstract
OBJECTIVE To evaluate the effect of external bleaching on the color and luminosity of inactive white-spot lesions (WSLs) present after fixed orthodontic appliance treatment as means for achieving color matching of the WSLs with adjacent tooth surfaces. MATERIALS AND METHODS Ten patients with inactive WSLs after therapy with fixed orthodontic appliances were selected. At baseline, the lightness of maxillary incisors and canines was assessed with a colorimeter. Color determinations were performed in the area of the initial lesions (F1) and at adjacent, sound enamel areas (F2). Then, anterior teeth were bleached once with a bleaching gel for 60 minutes. After a break of 14 days, in-office bleaching was followed by a 2-week home bleaching period with daily home bleaching for 1 hour. After this, color determinations were repeated. Additionally, patients were asked to fill out a questionnaire to provide information about their degree of contentment with the treatment. RESULTS The lightness values of both the F1 and F2 regions were significantly higher after bleaching as compared with baseline. F2 L-values increased significantly more as compared with F1, indicating a better color matching of these two areas in comparison with baseline. All patients were satisfied with the outcome of the bleaching therapy. CONCLUSION External bleaching is able to satisfactorily camouflage WSLs visible after therapy with fixed orthodontic appliances.

Abstract
OBJECTIVE To evaluate the oral health-related quality of life (OHRQoL) of children by dental caries and fluorosis status. METHODS A random sample of South Australian 8- to 13-year-old children was selected. Caries data were collected from school dental service records to group children by combined deciduous and permanent tooth caries experience. Children were examined for fluorosis using the Thylstrup and Fejerskov (TF) Index to form groups by fluorosis scores on maxillary central incisors. Occlusal traits were recorded using the Dental Aesthetic Index. Children and their parents completed the Child Perception Questionnaire (CPQ) and the Parental Perception Questionnaire (PPQ) and a global rating of oral health (OH). OHRQoL indicators, rating OH as Excellent/Very good, and mean overall CPQ/PPQ scores were compared between groups by fluorosis scores and caries experience. Multivariate models were generated for both OH and CPQ/PPQ indicators. RESULTS Two hundred forty-two children (43.0 percent) had 0 decayed, missing, and filled primary and permanent tooth surface (dmfs/DMFS), while 170 (23.9 percent) had 5+ dmfs/DMFS. The prevalence of TF scores 1, 2, and 3 were 14.5, 9.5, and 1.9 percent, respectively. The proportion of children/parents rating OH as Excellent/Very good was significantly associated with children's caries experience. That proportion increased when fluorosis severity increased from a TF score of 0 to 2, but decreased with a TF of 3. Having low caries experience and better dental appearance were associated with parents' perception of good OH. Having mild fluorosis and more acceptable appearance were significant factors for children's perception of good OH. Caries and malocclusion were associated with lower OHRQoL, while having a TF score of 2 was associated with better OHRQoL in multivariate models for overall CPQ/PPQ scores. CONCLUSION Caries and less acceptable appearance showed a negative impact, while mild fluorosis had a positive impact on child and parental OHRQoL.

Abstract
OBJECTIVES To assess dental practitioners' views on the need to treat developmental defects of enamel (DDE). In addition, to identify factors associated with practitioners' treatment decision (tooth factors and dentist-related). METHODS A random sample of 300 Hong Kong dentists were sent a booklet containing computer-generated images of various forms of DDE and asked to rate the treatment need. In addition, some dentist-related information was collected. RESULTS The response rate was 79% (237/300). The majority of the dental practitioners considered that aesthetic treatment was indicated for people with DDE subtypes of brown demarcated opacities (51.0%), confluent/patchy plus staining and/or loss of enamel (80.2%), missing enamel (67.1%) and the combination of discolouration and diffuse opacities (83.1%); their decisions were in relation to the type (P < 0.001), size (P = 0.001) and colour (P < 0.001) of the enamel defects. Dental professionals who were older, self-employed, graduated from institutions overseas, or had postgraduate qualifications, tended to consider aesthetic treatment for the teeth that exhibited the milder forms of enamel defects (P < 0.05). CONCLUSIONS Dentists frequently perceive that DDE constitutes a 'great need' for dental treatment. Dentists' perceptions of the need to treat DDE is influenced by type, size and colour of DDE and associated with dentist-related factors, principally the age of the dentist.

Abstract
Fluorescence imaging hardware and software have been recently employed to assess demineralization due to early dental caries. Dental fluorosis also presents as diffuse surface hypomineralization of enamel and in principle similar measurement methods might be applicable to both. The caries analysis system requires the user to select an area of sound enamel around the lesion so that the affected surface can be reconstructed and the lesion subtracted. Whereas early caries presents as discrete isolated lesions fluorosis is characterized by diffuse opacities covering most of the tooth. Consequently it is difficult to use commercial QLF software for the assessment of fluorosis, as there is typically no sound area of enamel to use for reconstruction. This study describes a fluorescent imaging device capable of recording digital images of the anterior teeth and also software that is able to objectively measure fluorosis area and severity. A convenience sample of 26 subjects with a range of fluorosis from TF scores 0-3 took part in the study. The upper left central incisor of these subjects was scored for fluorosis using the TF index, photographed using a conventional digital camera and imaged using the fluorescence imaging device. The TF index was then used to visually score the digital photographs and the fluorescence images. The data from the fluorescence method demonstrated a strong correlation with TF scores from fluorescence images (Kendall's tau = 0.862). The fluorescence imaging method shows promise as an objective, potentially blinded system for the longitudinal assessment of enamel fluorosis in vivo.

Abstract
BACKGROUND Understanding socially relevant attitudes to fluorosis and dental caries is important. Previous studies have concentrated mainly on aesthetic implications. AIMS To investigate social judgements beyond the aesthetic, made when viewing digitally manipulated extraoral images of dental fluorosis of varying degrees of severity and images of dental caries. METHODOLOGY Using a response latency technique, which allowed both the direction and strength of attitudes to be measured, 40 volunteers made judgements on 144 image/characteristic combinations. RESULTS Participants made social judgements which extended beyond the aesthetic to factors such as sociability, reliability and cleanliness. Judgements on mild fluorosis were not markedly different from those made about the same individual with normal enamel, but severe fluorosis had a significant negative impact on social judgements. Untreated dental caries was judged less favourably than normal enamel and mild fluorosis. CONCLUSIONS Attribution of characteristics that go beyond the aesthetic are significantly influenced by altered tooth appearance.

Abstract
OBJECTIVES To develop a new model to establish teenagers' perceptions of the aesthetic impact of fluorosis, in the context of overall facial appearance. This web-based model was used to compare different degrees of fluorosis at any one distance, while also comparing the same level of fluorosis at different 'distances'. METHODS A 14-year-old subject was used as the model face. Different degrees of fluorosis were 'built-up' on this subject's teeth using digital simulation. A web-based questionnaire showed 30 photographs, displaying four levels of fluorosis, in addition to fluorosis-free, at five different 'distances'. The closest images were shown with and without retractors, while the more distant pictures showed more of the subject's face. Teenage pupils (n = 217) were then asked to grade the acceptability of the appearances and indicate if they would wish treatment for each such appearance. RESULTS At any one distance, acceptability fell as fluorosis level increased. When the same degree of fluorosis was compared at different distances, acceptability improved as the teeth were viewed from further away. Pictures taken without retractors had higher acceptability than those taken with retractors in place. CONCLUSIONS Teenagers can discriminate between various degrees of fluorosis. However, more distant viewing of fluorosed teeth, within the overall context of the face, improves acceptability of the appearance.

Abstract
OBJECTIVES A cross-sectional national survey to explore perceptions of dental fluorosis and to determine the proportion of people regarding fluorosis as aesthetically objectionable at differing levels of defect. METHODS A survey using a multistage stratified random probability sample of 6,000 UK adult households. Face-to-face interviews were carried out using a structured questionnaire and photographs of different levels of dental fluorosis. Respondents were interviewed about the parameters of satisfaction, attractiveness and need for treatment for dental fluorosis. RESULTS The proportion of respondents perceiving teeth as unattractive, unsatisfactory and requiring treatment increased with increasing severity of dental fluorosis. Using agreement between the three negative perceptions as a measure, 14% of the sample perceived mild dental fluorosis as aesthetically objectionable, 45% at moderate level and 91% at severe levels. CONCLUSION Negative perceptions of dental fluorosis were lower than reported previously. Three parameters were included in the approach to estimate aesthetically objectionable fluorosis which may provide a more realistic measure than those used previously. The nature of the index and the sample included suggest that findings of this survey provide a reasonable indicator of the likely impact of water fluoridation. Findings may have important implications for fluoridation policies in the United Kingdom and elsewhere.

Abstract
AIMS To determine the prevalence of perceived tooth discolouration in the United Kingdom and to investigate socio-demographic variations and satisfaction with own tooth colour. METHODS A national cross-sectional questionnaire study was carried out using a multistage random probability sample. Assessment of people's perceptions of their own tooth colour was conducted by asking study participants to match colour to the closest of a set of photocards demonstrating different levels of tooth discolouration. A separate question asked how satisfied they were with their tooth colour. Information on socio-demographic characteristics of the population were gathered at the same time. ANALYSIS Data was coded and entered into SPSS software. Descriptive statistics were used to determine the prevalence of perceived discolouration and satisfaction with own tooth colour. Bivariate and regression analyses were performed to explore the effect of socio-demographic variations. RESULTS The self-assessment exercise was completed for 3215 subjects. Half of the study population perceived their tooth colour to be normal and 6% perceived that they had severe discolouration, the remainder reported themselves to have levels of tooth discolouration between these two extremes. Satisfaction with tooth colour decreased with increased discolouration. Sex, age, income and smoking, had statistically significant effects on the prevalence of perceived discolouration (P< 0.01). CONCLUSIONS Half of the people in this study perceived themselves to have tooth discolouration. Results suggest that the general public is concerned about dental appearance in terms of tooth colour, indicated by public dissatisfaction with relatively mildly discoloured teeth. Findings may suggest that a further increase in the demand of tooth whitening services and cosmetic dentistry in general is likely. The changing emphasis and level of perceived dissatisfaction need to be taken into account in planning dental services. Evidence based approaches are needed for the appropriate management of patients who demand treatment of mild discolouration.

Abstract
BACKGROUND As part of a large-scale fluoridation cessation study, standardized examiners assessed 8,281 school-aged children for dental fluorosis using the Thylstrup Fejerskov index, or TFI, in which scores range from 0 (no fluorosis) to 9 (severe loss of enamel with change of anatomical appearance). METHODS Dentists, parents and children were asked to respond to a statement, "The color of these teeth (mine or my child's) is pleasing and looks nice." Agreement or disagreement with the statement was indicated on a five-level scale, with a rating of 1 representing total agreement with the reference statement. The authors used repeated-measures analysis of variance to ascertain differences in satisfaction with the esthetic appearance of the subject's tooth color across dentists', parents' and subjects' perceptions. RESULTS Girls were more critical of their tooth color than were boys; however, parents and dentists were more critical of boys' tooth color than of girls'. While younger subjects were more critical than older subjects, parents of younger subjects were less critical than those of older subjects. Dentists' ratings were not significantly associated with subjects' age group. Subjects with a TFI score of 1 or 2 were not significantly more critical than subjects with a TFI score of 0, while those with a TFI score of 3 of higher were. Similarly, only parents of subjects with a TFI score of 3 of higher had significantly different ratings. CONCLUSIONS The three stakeholders in the esthetic treatment of children-parents, dentists and patients-appear to see the potential outcome of such treatment differently. CLINICAL IMPLICATIONS Dentists should ensure that parents and children agree about the course of treatment, the rationale for undertaking it and the results that could reasonably be expected.

Abstract
OBJECTIVES To investigate which types of enamel opacity are effectively treated by the microabrasion technique and whether this technique could be used as a diagnostic aid to determine the aetiology of these defects. MATERIALS AND METHOD Thirty two patients who had enamel opacities affecting both upper central incisors were selected and the disfigurements were classified into four types: single line, multi-line, patched and diffused. The patient's previous medical history, possible history of fluoride ingestion, presence of taurodontism and family history of similar enamel defects were recorded. Both incisors were treated with Prèma abrasive paste mixed with 18% hydrochloric acid. The aesthetic improvements were assessed by the patients and their parents and their satisfaction level after the treatment was recorded. RESULTS Approximately two-thirds (65.6%) of the patients were satisfied with their appearance after microabrasion. Apart from four patients, the improved appearance was stable and acceptable to the remaining patients at the six month recall. Statistical analysis showed that acceptable improvement was found in patients with single line/patched types of defects but not in multi-line/diffused types (P = 0.03). However, the aesthetic improvement was not related to the patient's fluoride history, presence of taurodontism or the family history of enamel defects. CONCLUSION Microabrasion using Prèma abrasives with 1 8% HCI is effective in improving the appearance of enamel with single-line or patched opacities, indicating that these defects are a surface phenomenon. For the multi-line and diffused types, the defects appear to extend deeper into the enamel. The technique failed to assist in determining the aetiology of these defects.

Abstract
OBJECTIVE We compared estimates of fluorosis prevalence and risk attributable to fluoridation using an index applied to the entire dentition and to the maxillary anterior teeth. We also estimated the prevalence of perceived esthetic problems attributable to current fluoridation policy (Attributable Burden). METHODS Fluorosis prevalence estimates were obtained from the National Survey of Oral Health in US School Children (1986-87) for the 1839 survey children aged 12 -14 years who were scored for fluorosis, had never received fluoride drops or tablets, and had lived in only one home. For each child we calculated Dean's fluorosis index, and an anterior fluorosis index (value of the highest scored maxillary anterior tooth). We used each index to calculate risk of fluorosis attributable to fluoridation by subtracting at each level of severity the prevalence of fluorosis among those living in low fluoride areas (F <or= 0.3 ppm) from the prevalence among those living in optimally fluoridated areas (0.7 ppm F <or=1.2 ppm). Findings from five published studies were used to calculate risk of perceived esthetic problem attributable to fluorosis, by severity, i.e. the difference in the mean percentage of respondents who were satisfied with the appearance of their teeth with and without fluorosis. Finally, Attributable Burden was estimated by summing the products of risk of perceived esthetic problems attributable to fluorosis and risk of fluorosis attributable to fluoridation for each level of fluorosis severity. RESULTS Prevalence of fluorosis, very mild or greater, was 26% with Dean's Index, which was significantly higher than the 18% figure calculated with the anterior index. Using the anterior index, fluoridation was a risk factor for very mild (attributable risk = 15%) and mild fluorosis (attributable risk = 3%). Risk of fluorosis (very mild or greater) attributable to fluoridation was significantly higher when calculated from prevalence estimates using Dean's Index than estimates calculated with the anterior index (24% versus 18%). The mean values of risk of perceived esthetic problems attributable to very mild and mild fluorosis were 9% and 33%, respectively. CONCLUSION We found that approximately 2% of US schoolchildren may experience perceived esthetic problems which could be attributed to the currently recommended levels of fluoride in drinking water. The findings further suggest that both estimates of fluorosis prevalence and risk of fluorosis attributable to fluoridation will be higher when calculated with an index applied to the entire dentition. Data were unavailable for fluoridated toothpaste and diluted formula consumption, thus the risk of fluorosis attributable to fluoridation may be overestimated if consumption was higher in fluoridated areas. The risk of perceived esthetic problems attributable to fluoridation must be weighed against its lifetime benefits and the associated costs of alternative solutions such as educating parents about appropriate toothpaste use and lowering the fluoride content of children's toothpaste.

Abstract
AIMS The aim of this study was to investigate the effects of pumicing and acid etching on the remineralisation of enamel opacities using quantitative measurement methods. METHODS Teeth with diffuse opacities were subjected to a treatment sequence of: (a) pumicing for 30-35 seconds (b) etch with 37.5% phosphoric acid for 2 minutes, (c) pumicing for 30-35 seconds and (d) etch for 1 minute, or served as controls. Both groups were then placed in a remineralising solution containing 1.5 mmol/L Ca2+ for 3 weeks. Mineral content changes were measured using contact microradiography and x-ray microtomography. In addition, the reflectivity of the opacities was monitored with infrared reflectance. RESULT The treatment sequence removed 34 +/- 4 microns of the surface enamel but no mineral loss was observed in the subsurface layer. The treatment sequence enhanced the formation of a new remineralised surface layer with a mean thickness of 22 +/- 3 microns. This new surface layer was less reflective. CONCLUSION Pumicing and acid etching can be used as a simple technique for the conservative treatment of enamel opacities.

Abstract
The authors surveyed parents of 708 patients in a pediatric dental practice about their satisfaction with the color of their children's teeth and factors associated with their level of satisfaction. Overall, 43 percent of parents were dissatisfied with their children's tooth color, and 78 percent of children had a Tooth Surface Index of Fluorosis, or TSIF, score greater than 0. The worst TSIF score was the only factor associated with parent satisfaction.
