Item Comparison of diode laser and conventional method in treatment of gingival melanin hyperpigmentation(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Koca Ünsal, Revan Birke; Other; OtherABSTRACT Purpose: We aim to compare the scalpel and diode laser methods in the treatment of gingival hyperpigmentation in terms of postoperative pain and wound healing. Materials & Methods: Sixteen systemically healthy individuals requesting treatment for light or moderate gingival hyperpigmentation were enrolled for this study. The individuals were randomly assigned to treatment with the diode laser method or conventional scalpel method. Dummett oral pigmentation index was recorded at baseline. The VAS form was given to the individuals and postoperative pain and wound healing were compared on the postoperative 7th day. Comparisons between the groups were tested using the Mann-Whitney U test and P-value < 0.05 was considered significant. Results: The scalpel group showed total epithelialization, however, the laser group showed incomplete epithelialization. The scalpel group declared significantly higher pain perception in comparison to the laser group on the first and second days after the surgery (p=0,002 and p=0,038, respectively). No significant differences were found between the groups on the fourth and seventh day regarding pain perception (p>0,05). Also, no significant difference was observed in any comparisons between the pain perceptions of female and male individuals (p>0,05). Conclusion: Both scalpel and diode laser are obtained successful clinical results in the treatment of gingival hyperpigmentation. Although increased chair-time and impaired wound healing at one-week follow-up, intraoperative homeostasis and relatively less postoperative pain reveal the superiority of diode laser to the scalpel. The choice of the method may vary depending on the available equipment and preference of the patient and the clinician.Item Examination of damage on enamel surface due to removal of metal and ceramic brackets: a review(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Gundal, Hasan; Other; OtherThe primary objective of the current review is to examine the enamel cracks before and after debonding of metal and ceramic brackets. The variables evaluated are: size, shape, localization of the cracks and the adhesive remnant index. Braces should be removed from the enamel surface, after orthodontic treatment. Removing the brackets may damage the tooth enamel. The risk of enamel damage increases when removing ceramic brackets. Some researchers evaluated different debonding methods in order to find the one that would cause less damage on the enamel and some others evaluated the bond strength of both metal and ceramic brackets showing that enamel cracks are associated with the bond strength. More specifically, it has been demonstrated by some researchers that higher bond strength is correlated with increased number and size of enamel cracks. There are authors reporting that brackets with chemical retantion do not exhibit greater bond strength compared with brackets with mechanical retantion. On the other hand, some authors asserted that brakets with chemical retention produce significantly higher bond strengths than brackets with other types of retention basesItem Knowledge, attitude and practices of dental patients about cross-ınfection and ınfection control(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Tekbaş Atay, Meltem; Other; OtherObjectives: This study aimed to evaluate the patient’s knowledge, attitude, and practice of cross-infection control in dentistry. Materials and Methods: This cross-sectional study was conducted at the Dentistry Faculty of……….. University. A total of 250 patients (134 female and 116 male) aged 18 years and older (35.5±13.9) participated in the questionnaire containing questions to determine the knowledge, attitudes, and practices related to cross-infection and infection control. Required personal and socio-demographic data were obtained. Chi-square test was conducted for categorical variables. Kruskal Wallis and Mann Whitney U tests were used to compare questionnaire scores (p <0.05). Results: The majority of the participants (30.5%) reported that their sources of information on dental infection control were social media. Knowledge scores of females were statistically significantly higher than males (p=0.005) and participants living in the city were significantly higher than those living in the town (p=0.015). Knowledge scores of health-care workers were significantly higher than both other workers and unemployed/students (p=0.001, p=0.004, respectively). Regarding participants’ attitudes and practices, only 29.2% of the participants questioned the dentists about the contagious disease, and only 36% asked about the sterilization method of the dental instruments. The majority of participants perceived that wearing gloves, masks, eyewear, and face shield would protect both patients and dentists. Conclusion: Participants in this study demonstrated a satisfactory level of knowledge about cross-infection and infection control methods in the nowadays’ pandemic condition. However, dental health professionals should take additional efforts to educate and encourage dental patients.
