Abstract: Oral disease is one of the most common causes of death in some countries. Changing habits and diet, not observing oral hygiene, neglecting the importance and health of teeth are the most important causes of oral diseases, these diseases may be specific to the oral cavity or may contribute to the disease in humans as part of an incompatible substance. In the meantime, the field of image processing has been proposed to provide automatic systems for disease diagnosis. Among medical image processing methods, image edging is the process of identifying and changing the display of an image. The purpose of this study is to use the edge recognition method and compare it with previous algorithms to be able to more accurately identify oral tissue from biological materials used in teeth than in the past. In the present study, using the method of Image segmentation (edge detection) is labeled for each pixel, so that pixels with the same label have similar properties. Oral and dental tissue segmentation was performed. Quantitative analysis of the results showed an accuracy of over 80% of the proposed method for oral tissue diagnosis. So that by using the results, it is possible to best identify a person who has a lesion in the tooth or oral tissue.

Abstract: Aim: This ex-vivo study evaluated the efficiency of an Er, Cr: YSGG laser (2780 nm) at different power settings to remove smear layer from the apical third of mesial roots of first lower molars by using SEM. Materials & Methods: 42 mesial root canals of first mandibular molars (type II Vertucci) were divided into 4 groups of 10 teeth each. The rest 2 teeth were used as control groups. After coronal access, all teeth were instrumented by Protaper Gold rotary files up to size F2 (25/0.08), followed an irrigation protocol with saline. Then, the experimental groups were irradiated by Er, Cr: YSGG laser. Four different output powers were tested, namely 1.25 W, 1.5 W, 2 W, 2.5 W was used to irradiate the roots in Group 1 (G1), Group 2 (G2), Group 3 (G3) and Group 4 (G4) respectively. Control group (n=2) was instrumented as experimental groups but not irradiated. Teeth were sectioned longitudinally and observed under SEM. Results were statistically analyzed with the Kruskal-Wallis Test and Mann-Whitney Test. Results: None of the tested groups succeeded in removing completely the smear layer from apical dentinal walls. The results showed no statistically significant differences between laser groups in removing smear layer from apical third of lower molars. Group 3 (2 W) showed better outcomes but it was not statistically significant. Conclusion: The outcome of the present study showed that laser-assisted smear layer removal with an Er, Cr: YSGG laser with the tested parameters is not predicable for the apical third of root canals. Clinical significance: The presence of chelating factor may play an important role in the mechanism of laser-assisted removal of smear layer in the apical third of root canals. Further research needs to be performed in order to find the optimal irradiation protocol.

Abstract: Background: The teeth with dental trauma in children are mostly young permanent teeth of school-age children. Once trauma occurs, it will have adverse effects on children's masticatory function, occlusal relationship, beauty, growth and development. Objective: To improve the success rate of replantation of completely dislocated teeth. Methods: Through literature review, we focus on “Tooth Injuries, Complete Dislocation, Replantation” to understand the current rescue measures of dislocated teeth, and conceive a rapid cleaning and portable storage device for dislocated teeth. Results: A device for rapid cleaning and portable preservation of dislocated teeth was successfully designed. Setting the ultraviolet sterilization lamp can play the role of irradiation sterilization and setting the mesh vertical plate can prevent the violent collision of multiple teeth when cleaning. It is possible to divide the storage slot space by setting the baffle, so as to achieve the purpose of classified storage. Conclusion: A rapid cleaning and portable storage device for dropped teeth is described, which solves the problems that the existing rapid cleaning and portable storage device cannot clean teeth uniformly, the cleaning effect is poor, and the cleaned teeth cannot be stored at low temperature.

Abstract: Objective: Periodontitis is linked to increased prevalence of cardiovascular disease and it is significant to have a comprehensive cognition on the mutual influence for combined treatment. The present investigation aimed to promote oral health instruction to patients with periodontitis and/or cardiovascular disease and the medical staffs from the department of cardiology and stomatology. Materials and Methods: A total of 120 Cardiologist and dentists and 120 patients with cardiovascular diseases were randomly investigated in Hainan public hospitals. The subjects' cognition of the correlation between cardiovascular disease and periodontitis were examined through questionnaires. Results: The public represented by patients with cardiovascular disease in Haikou City has a lack of cognition of the two-way relationship between periodontitis and cardiovascular disease. 32.1% of medical staff and 72.2% of patients did not know that "periodontitis is a cause of cardiovascular disease", and 83.5% of patients did not know that "periodontitis is a complication of cardiovascular disease". 96.3% of dental medical staff and 87.9% of cardiovascular medical staff expressed the willingness to popularize the correlation between the two diseases to patients. Conclusion: The public in Hainan has insufficient understanding of the correlation between periodontitis and cardiovascular diseases. Clinicians should strengthen the education on the bidirectional relationship between periodontitis and cardiovascular disease.

Abstract: The effect of age in years, food consumption pattern and prevalence of Dental carries among preschool children in settlements of Owerri metropolis, Imo State, Nigeria was investigated. It was aimed to determine the related risk and causative factors of early childhood caries among preschool children residing in areas of Owerri, Imo State. The schools used for this study were Imo State University staff school, Orlu road primary school, Owaelu- Uratta primary school and Nekede primary schools respectively. Data were collected through a questionnaire and were distributed to the parents of the preschool subjects under the study area. The data were analysed using frequencies and percentage and, the mean results obtained were analysed using ANOVA (SPSS 2.10 version). The research revealed, incidence of caries of between 5-50% following findings. Dental caries is associated with parental occupation with 50% and among the rural areas studied; Owaelu- Uratta primary school had the highest caries risk with 40%. However, risk factors of dental caries observed ranged between 2.5% to 57. 5% and 7.5% to 77.5% for pre- school children. Prescisely. Orlu road primary school had the least caries risk with 5%. The highest risk factor was found to be as a result of food consumption pattern of frequent sugar intake, ready availability of snacks, also occasional and ineffective cleaning or brushing of teeth. However, the lowest risk factor was seen as a result of drinking fluoridated water, low sugar intake and frequent cleaning of teeth. The study recommended that dietary counseling should be encouraged to parents and care givers so as to modify the children’s diet, inclusion of dental health care in school curriculum at all levels and also the socio-economic status of families should be raised through increasing their income and wages.
