The resorption of the residual alveolar ridges is a chronic and continuous process of bone remodeling. The aim of this study was to analyse the rate of residual ridge resorption at different sites in ...the both jaws in complete denture wearers, through a five-year period of denture wearing. Residual ridge changes were measured on successive lateral cephalograms at 5 measurement points of the maxilla and the mandible. The first lateral radiograph was obtained at the delivery of complete dentures. The second lateral cephalogram was obtained after five years of denture wearing. Measurements were performed using a calibrated grid. The results of this study showed the existence of a significant alveolar ridge resorption at all five measurement points of the maxilla and the mandible. The observed variables, such as body mass index and the night time denture wearing had no significant influence on the rate of residual alveolar ridge resorption (p > 0.05). The duration of edentulousness had a significant influence on the rate of residual ridge resorption with significantly higher amounts of alveolar bone height decrease in those patients who had lost the last remaining teeth more recently.
People with intellectual disability (ID) usually have a poor quality of oral health, which include poor oral hygiene, untreated caries and high proportion of missing teeth. Due to their fear and ...repulsive attitude towards medical staff general anesthesia is often a useful method for dental treatment. One thousand and fifty four intellectual disability patients for the period of 1985-2009 who received dental treatment under general anesthesia in Dental Polyclinic Split, were included in the study. Patients were divided into five groups based upon the period when a specific dental treatment had been received. Each period was analyzed for the number of ID patients treated and the type of dental treatment. The results showed that the most services provided were 4006 fillings, followed by 3225 extracted teeth and finally 274 endodontic treatments. Significantly the lowest number of fillings and endodontic treatments were found among patients in group II (1990-1994), with significantly the highest number of extracted teeth. In Conclusion, the types of dental treatment have changed during twenty five years. Number of extracted teeth decreased while the number of fillings and endodontic treatment increased. However, dental status of people with intellectual disability should be improved with more restorative treatments and with better oral health prevention program.
Orthodontic therapy is associated with a more significant accumulation of dentobacterial plaque and impaired oral hygiene, which increase the risk of developing dental caries and periodontal disease. ...Therefore, it is crucial to educate orthodontic patients about proper oral hygiene maintenance and oral health before and during treatment. The aim of this pilot study was to implement evidence-based best practices related to oral hygiene in adult orthodontic patients and improve compliance. In addition to evaluating oral hygiene practices, another goal of the project was to assess the knowledge of orthodontic patients regarding oral health. Questionnaires with seven pre- (before) and post-test criteria (90 day after implementation) were developed based on the best evidence available. This project was conducted in a private dental clinic in Split, Croatia, and included 45 patients. The baseline audit showed a gap between clinical practice and the best evidence. Three criteria achieved a high compliance baseline, while after implementation, there were substantial improvements in compliance for all. The everyday use of mouthwash improved from 17.8% at baseline to 66.7% at follow-up, as did the use of interdental aids, which increased from 55.6% to 91.1%. Statistically significant differences were found in the total score for oral health knowledge between the baseline (6.67 ± 1.74) and the follow-up audit (7.78 ± 0.56, p ≤ 0.001). The strategies developed in this project were effective in providing essential information to adult orthodontic patients and improving compliance with evidence. Guidelines on this topic should be designed to assist orthodontists and patients in maintaining oral health and oral hygiene.
Abstract Background/purpose The use of dental adhesives in everyday dental practice has raised questions about their biologic safety. Their biocompatibility is a relevant aspect of the clinical ...success of these materials. The objective of this study was to evaluate the genotoxicity of dental adhesives ex vivo using a cytogenetic assay. Materials and methods Four materials (AdheSE, G-Bond, Excite, and Adper Single Bond 2) were tested on human peripheral blood leukocytes using a comet assay. Prepared materials were eluted in a saline solution for 1 hour, 1 day, and 5 days. The comet assay was used to evaluate primary DNA damage by measuring the tail length and tail intensity. A Kruskall-Wallis nonparametric test was used for the statistical analysis, with the significance level set to P < 0.05. Results None of the tested dental adhesives revealed a statistically significant increase in the tail length or tail intensity in treated leukocytes, independent of the applied dilution, elution duration, and polymerization form. A slight increase in the tail length and intensity of DNA molecules was observed after 1 and 5 days of the elution period at the lowest dilution (1:102 ) for all tested adhesives, only in their nonpolymerized form; however, these results were not statistically significant. Conclusion Under the conditions used in this study, all adhesives had acceptable biocompatibility in terms of genotoxicity.
Human bones decrease in quality and increase in porosity beginning at about the third decade of life. The aim of this study was to establish an equation to predict the maxillary and mandibular linear ...vertical resorption potential for elderly edentulous patients on the basis of the analysis of the cervical vertebrae in a single cephalometric radiograph. The morphology of the bodies of the third and fourth cervical vertebrae and measurements of linear vertical resorption in the frontal region of the jaws were analyzed in two consecutive cephalometric observations of 26 elderly edentulous patients over the five-year period of wearing complete dentures. An equation was determined to obtain maxillary and mandibular linear vertical resorption on the basis of measurements in the third and fourth cervical vertebral bodies and the average errors between the predicted and the actual values were 0.14 mm. The cervical vertebrae exhibited significant decrease in the height and width, and residual alveolar ridges exhibited significant decrease in the height over the 5-year period of wearing dentures (p < 0.01). These results suggest that using cervical vertebral measurements might allow predicting the maxillary and mandibular resorption for edentulous elderly patients wearing complete dentures.
