ObjectivesThe purpose of this study was to evaluate self-reported oral health attitude and behavior among a group of Turkish dental students and to compare differences in oral health attitudes between years of study and gender.MethodsThis study included 267 (153 female, 114 male) dental students. A modified English version of Hiroshima University Dental-Behavioral Inventory (HU-DBI) which consists of twenty-eight dichotomous responses (yes-no) was used.ResultsTotally 141 preclinical (1, 2 and 3rd years of study) and 126 clinical students (4 and 5th years of study) who were mean age of 21.16 participated in the study. Statistically significant differences were found between years of study for brushing each of teeth carefully, cleaning the teeth well without using toothpaste, using a toothbrush which has hard bristles and for having had their dentist tell that they brush very well. There were statistically significant differences between females and males for using a toothbrush which has hard bristles and using tooth floss regularly. Statistically significant differences were found for brushing each of the teeth carefully and using mouth wash on regular basis between smokers and non-smokers.ConclusionsThis study confirmed that oral and dental health behavior and attitudes and also their knowledge about oral and dental health care of dental students improved with increasing level of education while oral and dental health care of female students were better than males and oral and dental health care of non-smokers were better than smokers.
BackgroundPreoperative radiographic examination of impacted mandibular third molars (IMTM) is essential to prevent inferior alveolar nerve injury during extraction. The purpose of this study was to evaluate the correlation between cone-beam computed tomography (CBCT) and digital panoramic radiography (DPR) findings in preoperative examination of IMTM.MethodsThis retrospective study included 298 teeth in 191 individuals. The relationship between the inferior alveolar canal (IAC) and the IMTM (buccal, lingual, interradicular or inferior), the position of the IMTM with respect to the IAC (contact, no contact), the morphologic shape of the mandible in the IMTM region (round, lingual extended, lingual concave), the type of IMTM (vertical, horizontal or angular) and the number of roots of the IMTM were evaluated on CBCT images. DPR images were evaluated for the number of roots of the IMTM and for the most common radiographic findings indicating a relationship between the IAC and the IMTM (darkening of the roots, diversion of the IAC, narrowing of the IAC and interruption of the white line). Data were statistically analyzed with Cramer V coefficient, Kappa statistic, chi-square and Fisher’s exact test.ResultsThere was a significant difference in number of roots detected on DPR versus CBCT images. There was a significant association between the type of IMTM and the morphologic shape of the mandible on CBCT images. Darkening of the roots and interruption of the white line on DPR images were significantly associated with the presence of contact between the IMTM and the IAC on CBCT images.ConclusionsPanoramic radiography is inadequate, whereas CBCT is useful to detect multiple roots of IMTM. When darkening of the roots and interruption of the white line are observed on panoramic images, there is increased likelihood of contact between the IMTM and the IAC. CBCT is required in these cases.
The aim of this study was to compare the efficacy of using a dishwasher or different chemical agents, including 0.12% chlorhexidine gluconate, 2% sodium hypochlorite (NaOCl), a mouthrinse containing essential oils and alcohol, and 50% white vinegar, for toothbrush disinfection. Sixty volunteers were divided into five experimental groups and one control group (n = 10). Participants brushed their teeth using toothbrushes with standard bristles, and they disinfected the toothbrushes according to instructed methods. Bacterial contamination of the toothbrushes was compared between the experimental groups and the control group. Data were analyzed by Kruskal-Wallis and Duncan's multiple range tests, with 95% confidence intervals for multiple comparisons. Bacterial contamination of toothbrushes from individuals in the experimental groups differed from those in the control group (p < 0.05). The most effective method for elimination of all tested bacterial species was 50% white vinegar, followed in order by 2% NaOCl, mouthrinse containing essential oils and alcohol, 0.12% chlorhexidine gluconate, dishwasher use, and tap water (control). The results of this study show that the most effective method for disinfecting toothbrushes was submersion in 50% white vinegar, which is cost-effective, easy to access, and appropriate for household use.
Objective. This study aimed to evaluate the effectiveness of alternative methods for toothbrush disinfection. Methods. Two-hundred eighty toothbrushes were included in the study. The toothbrushes were divided into 7 groups and were contaminated by standardized suspensions of Lactobacillus rhamnosus (L. rhamnosus), Streptococcus mutans (S. mutans), Staphylococcus aureus (S. aureus), and Escherichia coli (E. coli). The following disinfectants were tested: 1% sodium hypochlorite (NaOCl), 100% and 50% white vinegar, microwave (MW) oven, ultraviolet (UV) sanitizer, and mouth rinse-containing propolis (MCP). Data were analyzed with Kruskal Wallis and Dunn's tests. Results. Statistically significant differences were found between different methods and control group for all tested bacteria. There were statistically significant differences between all test groups for all microorganisms. MW was the most effective for L. rhamnosus and 100% white vinegar was the most effective method for S. mutans and S. aureus. NaOCl was the most effective for E. coli. Conclusion. This study showed that 100% white vinegar was considered to be effective for tested microorganisms. Similarly, 1% NaOCl is cost-effective, easily accessible, and comparatively effective for toothbrush disinfection. Because these agents are nontoxic, cost-effective and easily accessible, they may be appropriate for household use.
Aim:The aim of this study was to evaluate levels of public awareness and knowledge about early signs and risk factors of oral cancer among a group of dental patients in Turkey. Methods and Materials:This study included 1022 participants. Sociodemographic information of patients was obtained. A questionnaire about awareness and knowledge of oral cancer and early signs and risk factors related to the disease was completed by two examiners. Data were statistically analyzed with descriptive analyses, crosstabs and chi-square tests. Results:In total 60.7% of participants had never heard of oral cancer. While 79.2% of the participants were unaware of the early signs related to oral cancer, 29.9% of them were unaware of risk factors of the disease. There were no statistically significant differences between age, gender, and education levels for awareness of risk factors. Statistically significant differences were found between age and gender and no statistically significant difference was found between education levels for awareness of early signs. Conclusion:This study showed that public awareness and knowledge about oral cancer were insufficient in Turkey. Clinical Significance:There is an important need to inform the public about oral cancer, its risk factors, and early signs of the disease. Media campaigns can be useful to raise oral cancer awareness.
