Self-perceived oral health and happiness

In recent years, studies investigating psychological states such as happiness in individuals’ health have increased. Aim: This study investigated a possible association between self-perceived oral health and happiness in university students. Methods: This cross-sectional study was performed in a cohort of university students who entered in the 2016 academic year at the Federal University of Pelotas, located in southern Brazil. Data were collected using a self-administered questionnaire, including demographic and socioeconomic characteristics, psychosocial traits, and oral health-related questions. Happiness was measured through a question accompanied by the Faces Scale of Andrews and Whitey. Poisson regression models with robust variance were used to assess the association between the exposure variables (oral health measures) and the outcome (happiness). Results: The prevalence of happiness was 48.6%. A significant association between happiness and oral health, including satisfaction with dental appearance (PR 1.86; 95% CI 1.73-2.01), oral health-related to quality of life (PR 1.19; 95% CI 1.09-1.31), and halitosis (PR 1.10; 95% CI 1.01-1.20), was found. Conclusion: Individuals who reported dissatisfaction with dental appearance, an impact on oral health-related to quality of life, and halitosis perceived themselves as unhappy.

Functional aesthetic rehabilitation and its impact on self-esteem

The study analyzes the relationship between dental esthetic rehabilitation and self-esteem in adult patients at the Inter-American Open University. The research focuses on how improving dental appearance through prosthetic-aesthetic interventions positively impacts patients' perception of themselves and their overall well-being. Using a qualitative approach, interviews were conducted and clinical documents were reviewed to capture the experiences of 11 patients. The results show that, following rehabilitation, patients experienced a significant increase in their self-esteem, satisfaction and emotional well-being. The study underscores the importance of addressing both functional and esthetic aspects in dentistry, highlighting how a healthy smile influences quality of life and social interaction, reinforcing the need for comprehensive care that includes psychological and emotional considerations

The Effects of Malocclusion Among Priests in Enugu, Nigeria: An Anglican Church-Based Study.

Malocclusion refers to the departure from the normal relationship of teeth to other teeth in the same and opposing arch. It can negatively impact on facial appearance and the quality of life of a person. The present study aimed to investigate the influence of malocclusion on the role of priests as counsellors and preachers in Nigeria as perceived by church members. This was a cross-sectional survey of 112 church members who completed an electronic questionnaire. Thirty-five (31.3%) participants said unattractive dental appearance (malocclusion) will impact negatively on their acceptance of the priest's gospel message. Twenty-seven (24.1%) said dental appearance will influence the choice of priest that they go to for counselling while 71 (63.4%) said it will not. The study found that though unattractive teeth arrangement did not significantly affect the priest's duties as it pertains to sermons and counselling, awareness on the importance of orthodontic care among the clergy is necessary and should be encouraged among all spiritual leaders.

Perception of dental appearance and aesthetic analysis among patients, laypersons and dentists.

Current concepts of beauty are increasingly subjective, influenced by the viewpoints of others. The aim of the study was to evaluate divergences in the perception of dental appearance and smile esthetics among patients, laypersons and dental practitioners. The study goals were to evaluate the influence of age, sex, education and dental specialty on the participants' judgment and to identify the values of different esthetic criteria. Patients sample included 50 patients who responded to a dental appearance questionnaire (DAQ). Two frontal photographs were taken, one during a smile and one with retracted lips. Laypersons and dentists were asked to evaluate both photographs using a Linear Scale from (0-10), where 0 represent (absolutely unaesthetic) and 10 represent (absolutely aesthetic). One-way analysis of variance (ANOVA) and t-test analysis were measured for each group. Most patients in the sample expressed satisfaction with most aspects of their smiles and dental appearance. Among laypersons (including 488 participants), 47 pictures "with lips" out of 50 had higher mean aesthetic scores compared to pictures "without lips". Among the dentist sample, 90 dentists' perception towards the esthetic smile and dental appearance for photos "with lips" and "without lips" were the same for 23 out of 50 patients. Perception of smile aesthetics differed between patients, laypersons and dentists. Several factors can contribute to shape the perception of smile aesthetic. To compare the perception of dental aesthetic among patients, laypersons, and professional dentists, to evaluate the impact of age, sex, educational background, and income on the judgments made by laypersons, to assess the variations in experience, specialty, age, and sex on professional dentists' judgment, and to evaluate the role of lips, skin shade and tooth shade in different participants' judgments. Patients sample included 50 patients who responded to DAQ. Two frontal photographs were taken: one during a smile and one with retracted lips. Laypersons and dentists were asked to evaluate both photographs using a Linear Scale from (0-10), where 0 represent (absolutely unaesthetic) and 10 represent (absolutely aesthetic). One-way ANOVA and t-test analysis were measured for each group. Most patients in the sample expressed satisfaction with most aspects of their smiles and dental appearance. Among laypersons (including 488 participants), 47 pictures "with lips" out of 50 had higher mean aesthetic scores compared to pictures "without lips". Whereas among the dentist sample, 90 dentists' perception towards the esthetic smile and dental appearance for photos "with lips" and "without lips" were the same for 23 out of 50 patients. Perception of smile aesthetics differed between patients, laypersons and dentists. Several factors can contribute to shape the perception of smile aesthetic.

To appreciate the influence of contributed determinants on dental care utilization in the context of socio-economic inequalities

BackgroundTo appreciate dental care utilization in ‌the context of socio-economic inequalities, it is imperative to identify sources of inequalities and evaluate the extent to which dental care utilization is still related to socio-economic status. This study aimed to quantify the influence of contributed determinants on dental care utilization in the context of socio-economic inequalities amongst adults residing in Tehran metropolis.MethodsIn this cross-sectional community-based study, a stratified random sample of 1,510 subjects aged over 18 years was investigated by the zero-inflated Poisson analysis to measure the effect of determinants on utilization of dental care, and concentration index as well as the decomposition approach to identify the contributions of deterministic variables to the socio-economic inequality. Data was obtained by employing a phone interview survey. Individuals who were not willing or able to answer the questions in the telephone interview due to hearing or neurological problems did not participate in the interview. Dental care utilization was measured using the number of dental appointments.ResultsGender (male), oral health-related behaviors (such as brushing and dental flossing), experience of toothache, and concern about dental appearance were associated with an increased likelihood of utilizing dental care. Individuals who belonged to advanced age groups and lived alone significantly underutilized dental care. The concentration index equaling 0.05 (SE = 0.05) corroborates a pro-rich inequality. Decomposition analysis demonstrated the impact of oral health-related behaviors (i.e. dental brushing and use of dental flossing), concern about dental appearance, toothache, gender (male), insurance coverage of dental care, and smoking habit on the poor-rich gap in the dental care utilization.ConclusionsThe influence of socio-economic inequalities on dental care utilization is discernable along the entire spectrum of socio-economic status. Individuals with lower socio-economic status experience more underutilization of dental care. Community subgroups, particularly the more deprived bracket, require consideration from key stakeholders, including policymakers and health professionals for the enhancement of dental care utilization as revealed by underlying determinants.

CLINICAL LONGEVITY OF DIRECT RESIN-BASED COMPOSITE VENEERS ON ANTERIOR TEETH

Introduction: The growing demand for smiles' aesthetic improvement leads direct resin-based composite (RBC) veneers to gain increasing ground when it comes to renewing patients' dental appearance, mainly due to RBC cosmetic properties and the minimally invasive approach related to them. However, it is essential to know the success and survival rates and the main causes of failure of this technique. Objective: The aim of this study was to study the clinical longevity of direct RBC veneers on anterior teeth. Method: PICO framework guided the search strategies in the Pubmed, Google Scholar, and Periódicos Capes databases using a combination of the terms "composite resins, direct veneers, dental veneers, and longevity". Inclusion criteria was clinical follow-up studies of least 6 months, published in English from 2003 onwards, evaluating the performance of RBC veneers in anterior teeth. Books, book chapters, theses, editorials, in vitro studies, and articles that did not provide clinical follow-ups of RBC veneers were excluded. Using language (English) filter, 636 scientific articles were found, which were analyzed following the PRISMA statement and discarded if they did not meet the criteria. At the end, only four articles were selected, and their data collected. Conclusion: There was great variability in the time and criteria used to evaluate restorations in different studies, but the literature considers that direct RBC veneers have an acceptable clinical longevity, but may require repair appointments, and the main cause of failure.

White Spot Lesions in Fixed Orthodontics: A Literature Review on Etiology, Prevention, and Treatment.

White spot lesions (WSLs) are a common complication after treatment using fixed orthodontic appliances. Decalcification of enamel surrounding fixed orthodontic appliances, known as WSLs, poses a significant aesthetic difficulty during and after treatment, as the purpose of fixed orthodontic therapy is to improve facial and dental appearance. Modern dentistry utilizes remineralization therapiesto non-invasively treat WSLsto prevent the progression of disease and enhance the strength, appearance, and functionality of the affected tooth. This review aims to identify and assess the etiology, formation, and risk factors, as well as current treatment approaches used in achieving WSLs remineralization, induced by fixed orthodontic appliances.An electronic search on the PubMed and ScienceDirect databases was performed using a selected keyword.A total of 172 studies (from 2013 to 2023) were retrieved. Their references were also checked to find other relevant studies. Duplicate copies were excluded. After the abstract and full-text screening, only 39 studies were included. Even though numerous studies address the different treatment modalities for managing post-orthodontic WSLs, such as antiseptics; fluoridessuch as dentifrices, mouthwash, and varnish, and remineralizing agents such as casein phosphopeptides amorphous calcium phosphate, biomimetic self-assembling peptides, lasers, bleaching, microabrasion, and resin infiltration. There is a lack of evidence-based studies that examine the long-term effects of WSLtreatment. Further well-performed controlled clinical trials with long-term follow-up are needed to establish best clinical practice.

Bridging the Gap: Soft Tissue Considerations in Dental Implants From Microscopic to Macroscopic Levels.

Successful dental implant therapy not only relies on osseointegration but also on the health and stability of the surrounding soft tissues. Soft tissue concerns are critical to the long-term success of dental implants, influencing both function and appearance. This reviewlooks at soft tissue integration with dental implants from both microscopic and macroscopic viewpoints. It investigates the biological mechanisms, therapeutic management, and factors that influence soft tissue health around implants. By exploring these issues, the review hopes to provide a full understanding of the importance of soft tissue considerations in dental implantology.

Evaluation of Knowledge and Attitude of Adults Towards Comprehensive Orthodontic Treatment Among Dakshina Kannada Population - A Questionnaire Based Study

Aim and Objectives: To evaluate the knowledge and outlook of adult patients towards orthodontic treatment and identify the motivating factors behind their decision to seek such treatment, a study was conducted. The study also aimed to determine if increasing age posed a barrier to seeking orthodontic care and to gauge the overall attitude of patients towards adult orthodontics.  Methodology: A sample comprising 385 adult patients aged between 18 and 35 years, who were seeking orthodontic treatment, was surveyed. These patients completed a questionnaire prior to commencing treatment. Results revealed that the majority of adult patients recognized the necessity of orthodontic treatment during adulthood. Additionally, dissatisfaction with their dental appearance, particularly regarding their smile, was a significant motivator for seeking treatment at this stage of life.

Effectiveness of nanosilver fluoride and silver diamine fluoride in arresting early childhood caries: a randomized controlled clinical trial

BackgroundOne of the most prevalent health problems affecting children worldwide is untreated caries in primary teeth. Agents to arrest caries are used to manage untreated decay in children in disadvantaged communities. Nano Silver Fluoride (NSF) overcomes the staining problems of Silver Diamine Fluoride (SDF). This study compared the clinical cariostatic effect of NSF to 38% SDF for arresting caries lesions.MethodsThe study included 360 children younger than 4 years, with at least one active lesion, ICDAS score ≥ 3, recruited from nurseries in a rural area in Alexandria, Egypt, in 2022. They were randomly assigned to receive a single application of NSF at baseline, or two applications of SDF at baseline and after 6 months. The arrest of active carious lesions was assessed after 6 and 12 months using ICDAS criteria, and parents’ satisfaction with child appearance was also assessed. Chi-Square test was used to compare the groups and multi-level multiple logistic regression was used to assess the effect of the intervention on caries arrest at lesion level and binary logistic regression was used to assess the effect at patient level.Results1853 active lesions were included in children whose mean (SD) age was 42.3 (8.2) months. The arrest rate was significantly higher in the NSF than the SDF group at lesion level (78.4% and 65.0% at 6 months and 71.3% and 56.3% at 12 months, p < 0.001). In regression analysis, NSF had significantly higher odds of caries arrest than SDF at lesion level (at 6 months, AOR = 2.57, 95% CI: 1.55, 4.26 and at 12 month, AOR = 3.27, 95% CI: 1.89, 5.67). Parents of children receiving NSF had significantly greater satisfaction with their children’s dental appearance than those receiving SDF: (97.2% and 76.1%, respectively, p < 0.001).ConclusionNSF demonstrated greater effectiveness in arresting caries in preschool children without inducing black staining of teeth and with greater parental satisfaction than SDF. NSF can be an alternative to SDF in arresting caries especially in underprivileged communities.Trial registrationThe trial was registered in the clinicaltrials.gov registry (#NCT05255913)-16/02/2022.

Self-perceived oral health and orofacial appearance in older adults - an 18-year follow-up study in Karlskrona, Sweden.

To analyze whether self-perceived oral health and orofacial appearance change with increasing age. This longitudinal study is based on data from a questionnaire used in the Swedish National Study of Aging and Care. The sample comprises 160 participants 60 years of age at baseline 2001-2003. The same participants were re-examined at 66-, 72-, and 78 years of age. To analyze whether perceptions of oral health and orofacial appearance changed with increasing age, Cochran's Q test was conducted. Statistical significance was considered at p ≤ 0.05, and the calculated value Q must be equal to or greater than the critical chi-square value (Q ≥ 7.82). Significance values have been adjusted for the Bonferroni correction for multiple tests. Self-perceived mouth dryness, both day (Q = 7.94) and night (Q = 23.41), increased over the 18-year follow-up. When divided by gender, significant differences were only seen for mouth dryness at nighttime. A decrease in sensitive teeth was perceived with increasing age, and an increase in self-perceived satisfaction with dental appearance, and a decrease in self-perceived problems with dental gaps between the ages of 60 and 78. These changes were, however, not statistically significant. Men experienced a higher proportion of discomfort with discolored teeth at age 78 than at 60 (Q = 9.09). Self-perceived oral health and orofacial appearance were relatively stable, with few changes over an 18-year follow-up.

Are changes in malocclusion associated with adulthood psychosocial well-being?

The purpose of this study was to investigate the longitudinal psychosocial effects of changes in malocclusion from adolescence to adulthood on oral health-related quality of life (OHRQOL), self-rated dental appearance, and overall life satisfaction. The Dunedin Multidisciplinary Health and Development Study is a longitudinal birth cohort study of 1037 children born at Queen Mary Hospital, Dunedin, New Zealand, between April 1, 1972 and March 31, 1973. Data on their health and development, including dental examinations, has since been collected periodically. Malocclusion severity was measured using the Dental Aesthetic Index in participants aged 15 and 45 years (data collected at age 18 years was supplemented for data missing at age 15 years). Other data collected included clinically assessed oral health (dental caries and periodontal disease experience) and self-rated dental appearance, OHRQOL, life satisfaction, and personality traits. Malocclusion data were available for 868 participants in adolescence and 834 aged 45 years. For those with a severe handicapping malocclusion at 15 years old, 46.6% who received orthodontic treatment transitioned to a resolved (ie, mild-moderate) malocclusion when aged 45 years, whereas only 16.2% of those who did not receive orthodontic treatment made that transition. A transition to a worse malocclusion was associated with impacts on OHRQOL when aged 45 years in the subdomains of functional limitation, psychological discomfort, and physical disability as well as worse self-ratings of dental appearance, and these findings were held after adjusting for potential confounders. Malocclusion was not associated with overall life satisfaction. Maintenance of acceptable occlusion after orthodontic treatment requires a strong emphasis on achieving and maintaining excellent dental health and avoiding chronic oral conditions such as dental caries and tooth loss. The long-term benefits of orthodontic treatment may diminish by midlife unless good dental health is maintained. Orthodontists have the responsibility to raise awareness among their patients on how to maintain good oral health after orthodontic treatment.

Effect of weight satisfaction on adolescent facial and dental satisfaction.

To investigate if facial and dental satisfaction is related to body fat percentage and body weight satisfaction. A self-administered questionnaire was applied to adolescents from a Private School in Southern Brazil containing sociodemographic (sex and age) and self-perception variables. Adolescents were asked about their perceptions concerning dental problems. Body fat percentage was collected using bioelectrical impedance analysis. A total of 372 adolescents were examined. Most adolescents were satisfied with their dental (81.7%) and facial appearance (87.6%), while 39% of adolescents were satisfied with their body weight. Poisson regression model showed that adolescents who expressed satisfaction with their body weight (PR = 1.12, 95%CI1.06-1.19) and were satisfied with their dental appearance (PR = 1.24, 95% CI 1.08-1.41) exhibited a positive association with facial satisfaction. Adolescents dissatisfied with dental color (PR = 0.88, 95%CI 0.80-0.97), those reporting dental pain (PR = 0.88, 95%CI 0.80-0.97), and individuals with obesity (PR = 0.91, 95%CI 0.83-0.99) demonstrated a decrease in facial satisfaction. Adolescents aged 16 to 19years (PR = 1.08, 95% CI 1.01-1.15) and those satisfied with their facial appearance (PR = 1.20, 95%CI 1.01-1.43) exhibited a higher prevalence of dental satisfaction. Conversely, adolescents dissatisfied with dental color (PR = 0.74, 95% CI 0.66-0.82) and those with misaligned teeth (PR = 0.63, 95%CI 0.55-0.73) reported lower levels of dental satisfaction. Parametric g-formula analysis found that the association between body fat and facial satisfaction was mediated by body weight satisfaction (p = 0.001). While dental satisfaction was not influenced by corporeal characteristics, facial satisfaction was influenced by dental and body weight satisfaction. Obese adolescents had low facial satisfaction.

Association between dental appearance satisfaction and sociodemographic characteristics in Samarinda city, Indonesia

Background: Confidence in the appearance of teeth affects a person's physical and psychological health. The appearance of teeth is influenced by factors such as age, gender, educational level and economic status. The aim of this study was to find out the relationship between dental satisfaction and sociodemographic characteristics. Methods: A cross-sectional study has been conducted on 384 people aged 17 to 45 years in Samarinda City, Indonesia. The research instrument is a questionnaire on age, gender, educational level, family income, and six satisfaction questions about tooth appearance. Data analyzed descriptively and tested chi-square. Results: A total of 222 respondents (57.8%) felt dissatisfied with the appearance of their teeth. Respondents with a younger age tend to be 1.262 times more dissatisfied compared to older ones. There was a significant relationship between age and satisfaction with the appearance of the teeth (p=0.017). No significant relationship was found between teeth appearance satisfaction with gender, educational level and economic status. Respondents who did not want to do orthodontic care tended to be 1.920 times more satisfied than those who wanted to do ortodontic treatment. The most desirable treatments respondents wanted to improve dental aesthetics were bleaching (57.6%) and orthodontist treatment (43.2%). Conclusions: There is a significant correlation between teeth appearance satisfaction and age factor in the Samarinda Indonesian population who are 17 to 45 years old; there is a meaningful relationship between desire for orthodontic care and teeth satisfaction.

Charting the Future of Oral Health: A Bibliometric Exploration of Quality-of-Life Research in Dentistry.

In recent decades, the focus of health research has shifted to the impact of disease or impairment on how people proceed, behave, and experience quality of life. People's lives are affected by oral diseases in various ways. Oral health-related quality of life (OHRQoL) is inextricably linked to general health and well-being, and it has far-reaching consequences for clinical practice and dentistry research. Particularly in Indonesia, increasing attention to OHRQoL is related to several concerning oral conditions, such as the extremely high number of cases of tooth decay and inflammation of dental supportive tissue that inexplicably lowers the population's OHRQoL. To date, there has yet to be a bibliometric study of OHRQoL research in Indonesia. We intend to map the existing scientific literature on OHRQoL research in Indonesia during the last five years and investigate its research gaps. Scopus and the Sinta Database (a national database through Google Scholar) were used to retrieve Indonesian OHRQoL research publications from 2018 to 2023. Bibliographic data were analyzed using SPSS Statistics 25.0 and VOS Viewer 1.6.19. The data demonstrate that the number of OHRQoL-related publications in Indonesia and the number of local writers have increased over time. More of these publications were published in prestigious national journals than foreign ones. The study found that local researchers tended to conduct OHRQoL research on children and older populations, raising the issue of tooth decay or tooth loss. Exploring other subjects, such as dental anxiety, patient satisfaction, chewing performance, aesthetics, and appearance, and other populations (people with oral cancer and other systemic conditions) could broaden the environment of OHRQoL research in Indonesia.

Perception, sentiments, and the level of awareness toward the dental implant among general population in Sulaimaniyah City, Iraq

BackgroundEdentulism is one of the most commonly encountered conditions affecting the oral cavity. Dental implants have emerged as a widely accepted treatment option prosthodontically. However, lack of public awareness and the cost of the treatment act as barriers to limit their applicability.ObjectivesTo investigate the perception, sentiments, and level of awareness toward dental implants among the general population in Sulaimaniyah City, Iraq.Materials and methodsA questionnaire-based survey was conducted on 1132 participants in Sulaimaniyah City, Iraq, from February 15, 2023, till August 15, 2023, to collect their sociodemographic data, knowledge and attitudes toward dental implants for their missing tooth/teeth.ResultsThe mean age of participants was 41.3 ± 14.6 years, and most (30.7%) belong to the age group 31–44 years. Also, most of them were males (63.6%), married (75.3%), educated (91.3%), from rural areas (82.3%), and had > 1 missing tooth (75%). Regarding the participants’ knowledge of dental implants, most had information (78.4%)/heard about it (83.3%), mainly from dentists (43.6%); however, least of them (21.5%) /their family members (43%) had replaced missing teeth by dental implants. Additionally, the participant’s attitudes toward the dental implant indicated that most of them were interested in replacing their missing teeth (88.8%) but did not do it due to financial reasons (87%) and considered replacement as a significant (92.5%) and safe process (79.2%). Also, most of them thought there was no substantial difference between artificial and natural tooth appearance/function (47.9%), preferred the delayed implant for dental implant (47.7%), and would like to do an implant due to problems in dental appearance, speech, or dental function (81.5%). Finally, significant/highly significant differences were seen between each participant’s factor (age, gender, marital status, education level, and residency) with most items of attitude/awareness toward dental implants.ConclusionsMost participants were aware of the knowledge and attitude of dental implants for replacing missing tooth/teeth, especially males, married ones, educated individuals, and those from urban areas; however, financial problems are the main obstacle. Additionally, the delayed implant is preferable for replacing missing tooth/teeth using dental implants among studied individuals.

Psychometric properties of the Arabic version of the perceived prosthodontic treatment need scale: Exploratory and confirmatory factor analyses.

It is crucial to take into account the concerns of dental patients about their prosthodontic needs when planning the course of treatment. However, there is a dearth of research that examines these needs among adult dental patients. This study aims to translate and validate the perceived prosthodontic treatment need scale (PPTN) in Arabic. The 17-item PPTN scale was translated from English into Arabic and completed by 206 patients seeking prosthodontic treatment in a dental hospital in Saudi Arabia. Data collection was carried out in September and October 2023. Exploratory factor analysis (EFA) was used to ascertain the underlying factor structure; a unidimensional scale was hypothesised and tested using confirmatory factor analysis (CFA), including several multiple model fit indices. The assessment of reliability was conducted using Cronbach's alpha. The convergent and discriminant validity of the final scale were examined. EFA produced an 11-item scale distributed into three factors that explain 65.43% of the total variance with eigenvalues > 1. All items showed acceptable reliability, ranging from 0.65 to 0.84. The first factor pertained to social issues, while the second item was concerning dental appearance. Lastly, the third factor included functional difficulties associated with tooth loss or dental problems. The results of the CFA demonstrate a satisfactory level of model fit, with the standardised factor loadings ranging from 0.51 to 0.89. Convergent and discriminant validity of the model factors were established. The translated questionnaire was deemed legitimate and would be useful in comprehending patients' perceived treatment requirements, hence contributing to the advancement of prosthodontic research and practical implementation.

A Minimally Invasive Esthetic Approach for Teeth with Molar Incisor Hypomineralization: a Clinical Case Report

Molar incisor hypomineralization (MIH) is a qualitative defect of enamel, clinically characterized by white or yellow/brownish demarcated opacities that affect permanent molars, often associated with permanent incisors. The etiology is multifactorial, including systemic and genetic/epigenetic factors. Defects of anterior teeth can negatively impact children since they might present lower self-esteem and socialization problems. Purpose: To describe a minimally invasive treatment for anterior teeth affected by molar incisor hypomineralization, performed with direct composite resin restoration and a universal adhesive system. Case Report: An 8-year-old patient sought dental care with complaints about her dental appearance, reporting suffering from school bullying. She presented a white-yellowish opacity on the maxillary right central incisor. After a clinical examination, she was diagnosed with molar incisor hypomineralization. To improve dental esthetics, a direct composite resin restoration was proposed. The enamel surface was prepared and etched with 35% phosphoric acid etchant solution for 15 seconds before applying the universal adhesive system. Two different shades of the composite were used for layering the material to disguise the defect without extensive removal of the dental structure. The result was satisfactory as it was possible to mask the opacity, reestablish enamel thickness, and improve the patient's quality of life. Conclusion: Conservative restorations comprising a universal adhesive system seem to bring desirable esthetic results for anterior teeth with molar incisor hypomineralization.

E-cigarettes and heated tobacco products impact on dental color parameters

ObjectivesAbstaining from tobacco smoking may not only improve general health, but also reduce teeth staining and restore teeth whiteness. Compared with conventional cigarettes, E-cigarettes (ECs) and heated tobacco products (HTPs) may offer substantial reduction in exposure to pigmented tar-like compounds of cigarette smoke. It is possible that improvements in dental color indices may be observed in those who have stopped smoking combustible cigarettes by switching to tar-free nicotine delivery products. MethodsThis cross-sectional study evaluated and compared dental color parameters by digital spectrophotometry among five different groups: individuals who currently smoke ; individuals who used to smoke but have quit ; individuals who have never smoked ; exclusive users of electronic cigarettes (former smokers) ; and exclusive users of heated tobacco products (former smokers) . ResultsDental whiteness in current cigarette smokers was notably worse compared with never and former smokers, (13.38 Whiteness Index for Dentistry (WID) units vs. 19.96 and 16.79 WID units). Remarkably high WID values (i.e., whiter teeth) were also observed in ECs (16.72 WID units) and HTPs users (17.82 WID units). Compared to current smokers, difference in dental whiteness for ECs and HTPs users was visually noticeable (ΔWID difference being on average > 2.90 units). The colour differences measured as delta E*(ΔE*) were all visually detectable except for the comparison between ex-smokers and ECs users for which no perceptible color difference was observed (0.415). ConclusionExclusive use of ECs and HTPs is associated with better dental color measurements than current smoking, suggesting that tar-free nicotine delivery technologies are unlikely to have negative effects on dental appearance. Clinical significanceUse of alternative nicotine delivery systems may be associated with cosmetic benefits with important implications for those smokers perceiving dental aesthetics as a significant problem. For these an oral-based narrative may be a much more significant reason to refrain from smoking than the fear of developing smoking-related diseases in future.
