Assessment of dental pain in children with intellectual disability using the dental discomfort questionnaire
(2021) Senirkentli, Guler Burcu; Tirali, Resmiye Ebru; Bani, Mehmet; 33499707
Objective: This study aimed to compare the Dental Discomfort Questionnaire (DDQ) scores in children with and without intellectual disability (ID) and to measure correlation between the total DDQ and the Decayed, Missing, and Filled Teeth (DMFT/dmft) scores, as well as the condition of the tooth causing pain. Method: This cross-sectional study included 81 children with normal intellectual development who attended the Departments of Pediatric Dentistry at two Turkish Universities and 80 children with different levels of intellectual disability who reported dental pain in special education centers. The 12-question DDQ (Turkish version) was applied to the parents of the patients with their consent. The relationship of the DDQ scores with tha of the DMFT/dmft, dental status, and demographic data was evaluated. Results: When the DDQ scores of children with intellectual disabilities were evaluated, it was found that the majority of the answers given to the questions were statistically similar (p < 0.05) to those of children with normal cognitive level. In the questions in which "pain when eating and brushing teeth" was evaluated, a higher score was obtained, which led to an increase in the total DDQ score (p < 0.001). There was a statistically significant difference between the groups in terms of the distribution of dental conditions (p < 0.001). When compared to the normal cognitive group, patients with mild and severe intellectual disabilities had more deep dentin caries, thoughy, frequent periapical abscess was less common in those groups (p < 0.001 and p = 0.022). There was no statistically significant relationship between DMFTscores. Conclusion: The DDQ was found to be a descriptive, functional, and easy-to-use questionnaire for children with intellectual disabilitiesin terms of detecting the presence of dental pain. No correlation was found between DMFT/dmft, dental status and DDQ scores.
A Neural Expert System Based Dental Trauma Diagnosis Application
(2019) Senirkentli, Guler Burcu; Sen, Seckin; Farsak, Oguz; Bostanci, Erkan
Dental traumas are frequently observed challenging medical situations that the dentists need to handle. This requires a quickly made correct diagnosis and treatment to prevent further complications. Follow up procedures also need to be properly planned for the treatment to be completed successfully. The main goal of this study is to develop a system that facilitates the diagnosis and treatment process for the general dentists and dental students by providing an easy method of accessing a standard guideline in dental traumatology. This system has a big advantage from another expert systems. By using neural network this system can create its own rule with examining previous diagnoses. Thus, the system can find new correlations never known before between symptoms. New correlations may provide faster and easier diagnosis. In this study, it was aimed to find new correlations by using multilayer perceptron algorithm in Weka framework. Although lack of scientific data, the system has showed us the capability of learning.
Proton Therapy for Mandibula Plate Phantom
(2021) Senirkentli, Guler Burcu; Ekinci, Fatih; Bostanci, Erkan; Guezel, Mehmet Serdar; Dagli, Ozlem; Karim, Ahmad M.; Mishra, Alok; 33557337
Purpose: In this study, the required dose rates for optimal treatment of tumoral tissues when using proton therapy in the treatment of defective tumours seen in mandibles has been calculated. We aimed to protect the surrounding soft and hard tissues from unnecessary radiation as well as to prevent complications of radiation. Bragg curves of therapeutic energized protons for two different mandible (molar and premolar) plate phantoms were computed and compared with similar calculations in the literature. The results were found to be within acceptable deviation values. Methods: In this study, mandibular tooth plate phantoms were modelled for the molar and premolar areas and then a Monte Carlo simulation was used to calculate the Bragg curve, lateral straggle/range and recoil values of protons remaining in the therapeutic energy ranges. The mass and atomic densities of all the jawbone layers were selected and the effect of layer type and thickness on the Bragg curve, lateral straggle/range and the recoil were investigated. As protons move through different layers of density, lateral straggle and increases in the range were observed. A range of energies was used for the treatment of tumours at different depths in the mandible phantom. Results: Simulations revealed that as the cortical bone thickness increased, Bragg peak position decreased between 0.47-3.3%. An increase in the number of layers results in a decrease in the Bragg peak position. Finally, as the proton energy increased, the amplitude of the second peak and its effect on Bragg peak position decreased. Conclusion: These findings should guide the selection of appropriate energy levels in the treatment of tumour structures without damaging surrounding tissues.
