BACKGROUND: This study adopts a novel approach of using single-item surveys to simplify the assessment of oral health status and behaviors among Japanese private sector employees. We aimed to establish the validity of self-reported oral health in relation to clinical dental examinations, and to elucidate the relationship between oral diseases, health behaviors, and self-assessments. A secondary aim was to explore the association of self-rated oral health with oral health behaviors.
METHODS: Self-administered questionnaires and dental examinations were obtained from 2262 Japanese private sector employees. Workers self-rated their overall oral health status according to five choices: \"very good,\" \"good,\" \"fair,\" \"poor,\" or \"bad.\" Self-reports were then compared with the results of clinical dental examinations, which included measuring the oral hygiene index (DI-S), the number of decayed teeth, periodontal status (Community Periodontal Index) and number of missing teeth. Convergent validity was also tested by examining the correlations of self-reported oral health status with oral health behaviors.
RESULTS: Overall, 30.8% of workers reported their oral health as \"poor\" or \"bad.\" \"Poor\" or \"bad\" oral health status was significantly correlated with missing teeth, periodontitis, and decayed teeth. However, lower correlations were found for gingivitis and the oral hygiene index. Most self-reported oral health behaviors were correlated with self-rated oral health; exceptions were \"tooth brushing instructions received in a dental clinic,\" \"having a primary-care dentist,\" and \"habitual snacking between meals.\"
CONCLUSIONS: Self-rated oral health provides reasonably valid data, and correlated well with clinically assessed oral health status, including dental caries, periodontal status, and tooth loss. Convergent validity was also found for oral health behaviors.

Early tooth loss in pediatric patients can lead to various complications, making quick and accurate diagnosis essential. This study aimed to develop a novel deep learning model for classification of missing teeth on panoramic radiographs in pediatric patients and to assess the accuracy. The study included patients aged 8-16 years who visited the Pusan National University Dental Hospital and underwent panoramic radiography. A total of 806 panoramic radiographs were retrospectively analyzed to determine the presence or absence of missing teeth for each tooth number. Moreover, each panoramic radiograph was divided into four quadrants, each of a smaller size, containing both primary and permanent teeth, generating 3224 data. Quadrants with missing teeth (n = 1457) were set as the experimental group, and quadrants without missing teeth (n = 1767) were set as the control group. The data were split into training and validation sets in a 4:1 ratio, and a 5-fold cross-validation was conducted. A gradient-weighted class activation map was used to visualize the deep learning model. The average values of sensitivity, specificity, accuracy, precision, recall and F1-score of this deep learning model were 0.635, 0.814, 0.738, 0.730, 0.732 and 0.731, respectively. In the experimental group, the accuracy was the highest for missing canines and premolars, and the lowest for molars. The deep learning model exhibited a moderate to good distinguishing power with a classification performance of 0.730. This deep learning model and the newly defined small sized region of interest proved adequate for classifying the presence of missing teeth.

BACKGROUND: The rapid growth of the older adult population in the United States and their increased risk of edentulism make it essential to analyze trends and factors associated with edentulism.
METHODS: Data were obtained from the Behavioral Risk Factor Surveillance System from 2012 through 2020. US- and state-level trend lines were reported. Multiple logistic regression analyses were used to evaluate the association between self-reported complete edentulism and demographic characteristics, chronic diseases, smoking status, and health insurance status. Multiple imputations were used to address the missing data.
RESULTS: A total of 771,513 (weighted n = 50,410,576) participants were included in the study. There was a significant (P = .021) downward trend in the prevalence of edentulism from 2012 (16.36%) through 2020 (13.54%). Having less than a high school education, being a smoker, being non-Hispanic Black, having an annual household income less than $75,000, and having chronic conditions, including diabetes, myocardial infarction, arthritis, depression, and stroke, were significantly associated with complete edentulism.
CONCLUSIONS: Despite a decrease in prevalence of edentulism, disparities based on race, income, and education still exist. Edentulism is associated with chronic diseases in older adults.
CONCLUSIONS: Public health initiatives should be aimed at reducing the impact of edentulism and improving overall quality of life among older adults. Community health programs allocating resources to improve access to affordable care, reducing precursors to edentulism, expanding dental coverage, and promoting oral and general health awareness are vital components of these efforts.

BACKGROUND: Edentulism 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.
OBJECTIVE: To investigate the perception, sentiments, and level of awareness toward dental implants among the general population in Sulaimaniyah City, Iraq.
METHODS: A 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.
RESULTS: The 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.
CONCLUSIONS: Most 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.

This case study offers a rare and difficult condition involving the impaction of teeth 11, 12, and 13, providing a severe dental challenge. A thorough examination was performed on the patient, which included clinical evaluations and radiographic examinations. Because the impacted teeth were causing discomfort and functional impairment, a multidisciplinary approach was required, which included surgical exposure followed by traction forces to level and align the impacted teeth. The abstract emphasizes the case\'s complexity, digging into the diagnosis process and the establishment of a personalized treatment strategy. The complexities of handling many impacted teeth are explored in length, including surgical intervention, orthodontic considerations, and postoperative care.

OBJECTIVE: When young patients are congenitally missing anterior teeth, different treatment modalities can be used to complement the dental arch. This article proposes a new treatment modality for the replacement of anterior teeth, the cantilever contact-point resin bonded bridge (CCP-RBB).
METHODS: In this proof of principle study, CCP-RBB\'s delivered by one operator were clinically assessed. Patients who were missing maxillary incisors and had suitable intra-oral conditions for a contact-point cantilever RBB were included. Three cases are presented to describe all adhesive steps. This proof of principle clinical study is presented with up to 60 months follow-up of the cantilever contact resin bonded bridges.
RESULTS: A total of 19 CCP-RBB\'s were evaluated after a mean period of 29.8 months. None of the restorations exhibited failure, carious lesions or fractures during the follow-up periods, demonstrating an absence of restoration debonding or the need for repair.
CONCLUSIONS: The new cantilever contact-point resin bonded bridge exhibited an excellent treatment modality without failure or debonding up to 5 years. More and extended duration in vivo studies are needed to evaluate this new treatment modality.
CONCLUSIONS: In this proof of principle the new cantilever contact-point resin bonded bridge obtained excellent results up to 5 years of clinical follow-up.

Oral health, a critical aspect of overall well-being, is influenced by various sociodemographic and lifestyle factors, with poor oral health associated with systemic diseases and diminished quality of life.
This cross-sectional study leverages data from the Hungarian European Health Interview Survey (EHIS) representative of the Hungarian population, to conduct a comprehensive examination of the intersection between these factors and oral health, aiming to identify potential risk factors and contribute to the development of targeted interventions. The research examined associations between sociodemographic/lifestyle factors and oral health. Statistical techniques included Pearson\'s Chi-square test, multivariate and ordinal logistic regression analyses. Weighting was applied to assure the representativeness of the population and enhance the validity of the survey results.
The study identifies gender, age, education, financial status, smoking, and self-perceived oral health as key factors influencing oral health outcomes. Notably, regular dental visits significantly reduced the risk of poor oral health and caries. Females, non-smokers, university graduates, high-income individuals, and those with good self-perceived health had fewer missing teeth and better self-perceived oral health. Teeth extractions due to decay, especially when not replaced, significantly increased the perception of poor oral health, while regular dental visits improved it.
The study highlights the need for personalized oral health interventions considering the different sociodemographic and lifestyle factors, along with promotion of healthy lifestyle, more frequent dental office visits and equitable dental care access. The findings offer the potential to inform regional oral health policies and prevention strategies, improving oral health and overall wellbeing.

OBJECTIVE: The aim this retrospective analysis was to evaluate the survival, success and possible complications of transplanted premolars to the anterior region subdivided in development stage and patient\'s age.
METHODS: The material comprised patients that underwent a tooth transplantation between April 2004 and December 2021. A total of 910 premolars were transplanted in 707 patients. Tooth mobility, oral hygiene, and periodontal parameters were clinically evaluated. Standardized radiographs were used to evaluate pulpal and periodontal healing and root formation. The cumulative survival rate was calculated using the Kaplan-Meier method.
RESULTS: The data were subdivided in three groups based on the stage of root development and patient\'s age. The average age at surgery was 16 years. The main indication for transplantation was trauma, followed by agenesis and other indications. Two premolars were lost during the whole observation period. The overall survival and success in the immature premolars group after an observation period of 10 years was 99.8%. The 10-year survival and success rate when fully developed premolars were transplanted in the anterior region in adolescents were 100% and 96.3%, respectively. In adults, the 10-year survival and success rate were 87.5%.
CONCLUSIONS: Transplantation of premolars with developing and fully developed roots to the anterior region in children, adolescents, and adults is a predictable treatment modality.

Background To evaluate the association of dental diseases and oral hygiene care with incidence of heart failure (HF) among patients with type 2 diabetes. Methods and Results This study included 173 927 patients with type 2 diabetes aged ≥40 years, who underwent Korean National Health Insurance Service health examinations in 2008 and were followed up until the end of 2017. Hazard ratios (HRs) and 95% CIs for HF were estimated using multivariable Cox proportional hazards regression analysis. During a median follow-up of 9.3 years, 1.94% of participants developed HF. An increased number of missing teeth was associated with a higher risk of HF (P<0.001). HRs of HF increased among individuals with ≥15 missing teeth (HR, 1.37 [95% CI, 1.14-1.64]) compared with those without missing teeth. Decreased risk of HF was observed in individuals with ≥1 time/year of professional dental cleaning (HR, 0.93 [95% CI, 0.87-0.99]) and in those with ≥2 times/d of toothbrushing (HR, 0.90 [95% CI, 0.82-0.98]) compared with those without these practices. While combined presence of missing teeth and periodontal disease (P=0.004) or dental caries (P=0.007) increased HF risk, combined oral hygiene care was associated with further HF risk reduction (P=0.024). Better oral hygiene care was associated with decreased HF risk, even as the number of missing teeth increased (P<0.001). Conclusions Among patients with type 2 diabetes, dental diseases and oral hygiene care are important determinants of HF development. Dental disease management and good oral care may prevent HF in patients with type 2 diabetes.

UNASSIGNED: The early tooth loss has an adverse effect on the overall well-being of an individual. The aim of the current study was to highlight the orthodontic complications of long-term tooth loss in the city of Najran.
UNASSIGNED: This was a cohort study of patients presenting for orthodontic rehabilitation. A total of 326 patients that presented for orthodontic rehabilitation were examined clinically and data such as age, gender, number of missing teeth, missing teeth, duration of missing teeth, tipping, and overerupted and rotated teeth were recorded. Patients that can be treated with orthodontic space closure were excluded from the study. Patients\' data were analyzed using IBM SPSS Statistics and results were presented as simple frequencies and descriptive statistics.
UNASSIGNED: Out of 326 patients that presented for orthodontic rehabilitation, 259 patients had missing teeth with its sequelae that will demand prosthodontic rehabilitation with a prevalence rate of 79.4%. There are 97 (37.5%) males and 162 (62.5%) females with M:F ratio of 1:1.7. The age ranged from 15 to 52 years with mean ± standard deviation (28.5 ± 8.5). The age group 21-30 years constitutes the group with the highest number of missing teeth. A total number of 595 (60.2%) teeth were missing, 173 (17.5%) teeth were tipped, and 124 (12.5%) teeth were overerupted, whereas only 97 (9.8%) teeth were rotated (n = 989). Fixed orthodontic appliances (FOAs) were used for all cases with rotation and FOAs + Mini Screws were used for all cases with tipping, overeruption, and/or combinations. The dental loss was managed by prosthesis depending on patients\' choice and financial capability ranging from removable/fixed prosthesis and dental implants.
UNASSIGNED: Orthodontic consequences of early tooth loss include tipping and rotation of adjacent teeth and overeruption of opposing teeth. Early acknowledgment of tooth replacement after tooth loss is essential in preventing long-term orthodontic adverse effects.
