This article discusses a study that examined the relationship between tooth loss and cardiovascular diseases. The study found a strong association between the number of lost teeth and heart valve diseases and cardiomyopathy. However, no significant associations were found for other cardiovascular diseases. The study also explored the impact of demographic factors on tooth loss and found that age, gender, and rural/urban residence were related to the number of lost teeth. The findings suggest that tooth loss may be a predictor of certain cardiovascular diseases, but more research is needed to fully understand the relationship. Additionally, a document of references and citations is provided, which can be helpful for researchers and individuals interested in the impact of tooth loss on overall health.

Introduction. Dental fatigue fractures are the result of occlusal overloads occurring because of increased intensity of occlusal forces or decreased resistance of dental hard tissues to habitual occlusal forces. In the COVID-19 pandemic, occlusal stress has increased significantly, and so has the number of dental fractures. The study has the aim to determine if the number of cases of dental fatigue fractures during the pandemic crisis was higher than in the immediately preceding period. Methodology. The retrospective study was carried out in a private dental clinic, selecting from the case series presented during March 2019-March 2021 the cases of dental fatigue fractures presented for diagnosis and treatment. The data collected from the patients included the reason for the presentation, the dental and medical history, and results from dental examination and radiological data. The statistical analysis was carried out with Microsoft Excel and SPSS software. Results. The study included 644 patients, 430 women and 214 men, with ages between 25 and 85 years (61±7.4 years). From a total of 2581 visits, 1534 visits were made to 383 patients between March 2019 and March 2020, and 1047 visits were made to 261 patients between March 2020 and March 2021, the number of visits decreasing by 31.75% during the pandemic. During the pandemic, the number of fractured teeth tripled, increasing from 0.53% to 1.53% (p=0.009). The most affected teeth were the maxillary premolars and the permanent first molar, both mandibular and maxillary. In most cases, the indication for treatment was extraction. Conclusions. The Sars-Cov2 virus pandemic crisis has significantly increased the number of teeth with dental fatigue fractures presented to the dental office for diagnosis and treatment. [ABSTRACT FROM AUTHOR]

Aims: The aim of this paper was to validate the Romanian version of an ageism scale for dental students. Materials and Methods: The initial 27‐item ageism scale was translated into Romanian and administered to 210 dental students in Craiova. The data were analysed using principal components analysis (PCA) with an orthogonal, Varimax rotation. The answers were then compared across several demographic variables using a combination of independent samples t tests and one‐way between‐subjects analysis of variance (ANOVA). Results: Adequate factorability was confirmed with a Kaiser‐Meyer‐Olkin (KMO) of 0.676 and a Bartlett's Test of Sphericity yielding P < 0.001. PCA revealed a 10‐item scale distributed into three components that accounted for 58% of the overall variance. The first component contained 4 items related to the cost‐benefit of providing care to older patients (α = 0.80). The second contained 3 items that revolved around the perceptions about older people and their value in the society (α = 0.59). The third contained 3 items related to gerodontology training (α = 0.46). Discriminant validity showed differences in the first component based on whether a student had an older family member. Conclusions: The 10‐item, three components scale demonstrated acceptable validity and reliability. [ABSTRACT FROM AUTHOR]

Introduction: This study investigated the distribution and magnitude of stress generated in the enamel of an upper first premolar, after applying normal and excessive occlusal loads in a vertical and horizontal direction, using Finite Element Analysis (FEA). Methodology: A 3D virtual model of an upper first premolar was analyzed. The CT images of the tooth were converted into 3D data using the program MIMICS and Finite Element Analysis (FEA) was used for the stress study. To better understand the distribution of stress generated by occlusal loading, the situation of the enamel in various 3D virtual models was presented. 14 scenarios for the occlusal loading of the virtual models of the upper first premolar were obtained and the areas with the highest concentration of stress were emphasized. Results: In the model with the tooth intact, stress values were higher than the admissible ones in the simulation of the excessive vertical loading, normal horizontal loading and excessive horizontal loading. Stress was found in the buccal cusp area and in the cervical area, mainly on the buccal side of the tooth. In the models with horizontal occlusal tooth wear, stress values were higher than the admissible ones in the simulation of the excessive vertical loading. Stress was found in the cervical area. In the models with oblique occlusal tooth wear, stress values were higher than the admissible ones in the simulation of the normal and excessive horizontal loading. Stress was found mainly in cervical area, on the buccal side of the tooth. Conclusions: The most harmful loads were the heavy vertical ones and the horizontal ones, no matter the magnitude.

Introduction: Root resorption is a pathological process characterized by loss of dental root substance, caused by bacterial infections, traumatic injuries or chemical irritation. Root resorption might be accidentally observed on digital panoramic radiography. Objective: The objective of the study was to identify characteristic radiological aspects for the different types of root resorption that could be observed on digital panoramic radiography, to make an easier diagnostic of root resorption. Material and Method: The retrospective study used the X-ray base from the Oral Rehabilitation and Dental Prosthetics Clinic of UMF Craiova to identify the most representative images for different types of root resorption. Digital panoramic radiographies were analysed by two investigators, of which the most suggestive images were selected and described. Results: Digital panoramic radiographies and dental charts of 240 patients were analyzed. 113 cases of root resorption were identified. External inflammatory root resorption (EIRR) was present in 27.07% of studied cases, external cervical root resorption (ECRR) was identified in 10.83% of all studied cases, external replacement root resorption (ERRR) was diagnosed in 7.08% of studied cases and internal root resorption (IRR) was the most rare type of root resorption, with only 2.08% from all studied cases. 16 cases were selected to describe the radiologic features of different types of root resorption, featuring the most interesting images of root resorption evident on digital panoramic radiographies. Discussion: Comparative analyses have been made between our results and the results of other specific studies, with both similar and different values. The radiological features which lead to the diagnostic of each type of RR were highlighted, assessing the causes that caused the lesions, as well as the treatment recommendations. Conclusions: Digital panoramic radiography is a useful tool to identify root resorption, since it has become the most common radiological investigation for diagnostic in dentistry. Description of radiological aspects of different types of root resorption on panoramic digital radiography allows faster diagnosis. Still, the CBCT may be recommended in some cases to confirm the diagnosis. [ABSTRACT FROM AUTHOR]

The purpose of the study was to analyze the prevalence of different forms of partial edentulism and the description of the various parameters associated with this disease. Materials and Methods. The study was conducted on a total of 204 subjects who presented themselves at the Clinic of Dental Prosthetics and Oral Rehabilitation Clinic of the Faculty of Dentistry Craiova between October 2015 and June 2016. Results. Of the 204 subjects diagnosed with partial edentulism, 51.47% belonged to the age group of 20-29 years, 52.46% were female and 82.84% came from the urban environment. The most frequent cause of the edentulism was dental caries and their complications. The present study has shown that the partial edentulism forms encountered, especially those of the Kennedy III class, had an increased frequency among the young population, especially in the maxillary arch.

Introduction.Fixed partial bridges represent the most used therapeutic method in oral rehabilitation in Romania. Survival rate of dental bridges is almost 90% after 10 years. Most failures of dental bridges are biological in nature, caused by a defective marginal fit of the dental crowns. The aim of the study is to establish the failure rate of dental crowns (components of dental bridges) and to show OCT application in evaluating their marginal fit. Materials and methods. Panoramic radiographs taken from 22 patients with fixed dental bridges underwent a marginal fit evaluation. 10 teeth covered with different types of crowns, extracted as a consequence of periodontal breakdown, were selected from 85 extracted teeth. Teeth were washed under running water, scaled to remove periodontal tissue and calculus, and then OCT scanned. For the experiment, we used an OCT system manufactured by Thorlabs (OCS1300SS) powered by a swept laser source with central wavelength of 1310 nm, a spectral bandwidth of 100 nm, and an average power of 12 mW. Results and discussion. Out of the 154 teeth covered with crowns, 6.493% showed poor marginal fit, especially the second molars. OCT examination showed multiple sectorial deficiencies in the cervical marginal fit of crowns, especially on second molars distal surfaces, a clinically and radiologically undetectable situation.Conclusions. OCT in dentistry was used for both hard and soft tissues, oral mucosa and periodontal tissues. Poor cervical marginal fit of the fixed prosthetic restorations is the most common cause of dental bridges' biologic failure. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the present study was to correlate etiological factors with noncarious cervical lesions in a group of patients from Craiova. Material and Methods: The study was conducted between November 2015 and May 2016 on 50 patients, aged 18-56 years, who addressed to the Oral Rehabilitation Clinic, from the University of Medicine and Pharmacy of Craiova. Patients were divided into two groups: the study group consists of patients who had noncarious cervical dental lesions (NCCLs) and the control group with patients who did not have noncarious cervical lesions. Each patient underwent a clinical examination and completed a questionnaire, referring to eating habits, oral hygiene, vicious habits and personal impressions about the appearance and functionality of his teeth, highlighting the factors involved in the noncarious dental lesions etiology. Results: The study group consisted of 64% women and 36% men. Noncarious cervical lesions were higher in men (72.22%) compared to women (56.25%). Regarding on the tooth brushing method, it has been noted that 34% of patients used a vertical tooth brushing method, 52% were using a circular brushing method, while 14% were practicing a horizontal tooth brushing method. Cervical sensitivity has been detected in 48% of the patients, against 52% who showed no sensitivity. 62% of the participants did not have bruxism, while nighttime/daytime bruxism was found in 38% of the patients. Conclusions: There are several etiological factors correlated with noncarious cervical lesions, among which are: tooth brushing method, bruxism, eating behaviors. [ABSTRACT FROM AUTHOR]
