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 Pre-eruptive Intra-coronal resorption: A report of two cases and review of the literature(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Jagtap, Rohan; Diş Hekimliği; Diş Hekimliği FakültesiPre-eruptive intracoronary resorption is a rare condition mainly affecting pediatric patients. It is a radiographic finding in the dentin of the crown of an unerupted tooth just below the enamel-dentin junction. It is visualized in radiographs as a radiolucent coronal lesion of variable depth; it is well-defined and located in the dentin adjacent to the amelodentinal limit of an unerupted tooth. Historically, this lesion was misdiagnosed as caries and was misnamed pre-eruptive caries, when in reality they were pre-eruptive intracoronal resorptions. We present two rare cases of pre-eruptive intracoronary resorption in patients that needed radiographs for orthodontic purposes. The Oral & Maxillofacial Radiologist detected the existence of pre-eruptive intracoronary resorption in mandibular second premolars and mandibular second molar. These radiographic findings provided the clinician with the advantage of knowing this condition before teeth eruption, allowing for conservative treatment and periodic radiographic follow-up.Item Comparison of the effectiveness of chemo-mechanical and traditional caries removal methods in primary teeth using micro-computed tomography(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Turgut Coşgun, Melike; Diş Hekimliği; Diş Hekimliği FakültesiObjective: The purpose of this study was to evaluate dentin mineral density before and after caries removal with the traditional caries removal technique and chemo mechanical method, with or without the use of caries detection dye. Our null hypothesis was that the chemo mechanical method with minimally invasive treatment would achieve an effect similar to that of conservative pediatric dentistry treatment. Forty-eight extracted human primary molar were used in this study. Materials and Methods: The two main study groups underwent treatment with the chemo mechanical and traditional methods. The teeth were then treated with chemo mechanical and traditional caries removal approach. Teeth were scanned with the same voxel sizes using micro-CT images to figure out the difference dentin mineral density and to calculate the removed (excavated) dentinal volume after chemo mechanical or traditional method application. Results: The results showed increase of cavity volume in the chemo mechanical and traditional method groups. No significant difference was found for cavity volume and dentinal carious volume in both groups (p˃0,05). The mineral density values of demineralized dentin were between 0.52-0.66 g/cm3 before caries removal, and 1.39-1.59 g/cm3 after removing caries. These values were found to be within the range of healthy dentin mineral density values again without any significant difference between groups (p˃0,05). Conclusions: In conclusion, chemo mechanical can be used effectively for removing the caries in the primary molar teeth similar to conservative treatments.Item Knowledge and awareness of turkish mothers regarding primary teeth(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Yıldırım, Sinem; Diş Hekimliği; Diş Hekimliği FakültesiPurpose: This study aimed to evaluate the mothers' knowledge and awareness of primary teeth. Methods: This cross-sectional study consisted of 323 children and their mothers. A questionnaire form consisting of 10 questions about the definition of primary teeth, their total number and treatment requirements was applied to the mothers. Pearson Chi-Square and Fisher-Freeman-Halton tests were used to analyze the data. Results: The rate of wrong answers given by mothers with low education level to the question "What are primary teeth?" was significantly higher (p <0.001). The rate of correct answer given by mothers with low education level to the question "How many primary teeth are there in a healthy dentition?" was significantly lower (p = 0.002). The answer of "no" given by mothers with a low education level to the question "Do you think it is necessary to treat primary teeth?" was significantly higher (p=0.016). The rate of correct answer given by families with a monthly income above 5000 TL to the questions "What are primary teeth?" and "How many primary teeth are present totally?" were significantly higher (p=<0.001). Conclusion: The superior the education level and the monthly income of the family, the higher the rate of answering questions that require information.Item Full-mouth reconstruction with ımplant and tooth-supported zirconia restorations in a digital workflow(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Oğuz, Ece İrem; Diş Hekimliği; Diş Hekimliği FakültesiZirconia has become a popular restorative material regarding the mechanical and biocompatibility advantages. Monolithic and translucent forms of zirconia advanced the aesthetics of this material, making it the material of choice for both tooth- and implant- supported restorations. Also, digital fabrication of zirconia not only enables accurate restorations but also provides time efficiency. The present case report demonstrates the rehabilitation of a patient who has generalized tooth wear with implant- and tooth-supported monolithic zirconia restorations with buccal veneers in a newly established occlusal vertical dimension. The treatment process was completed in a digital workflow as the impressions were taken with a powder-free intraoral scanner and the digital data were send to the dental laboratory to fabricate the restorations. Monolithic zirconia restorations with buccal feldspathic veneers were completed without any adjustments in only two appointments. The patient was satisfied and the restorations have been in service for two years.Item 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.Item Evaluation of different beverages’ effect on microhardness and surface roughness of different artificial teeth(Ankara Üniversitesi Diş Hekimliği Fakültesi, 2021) Özkan, Pelin; Diş Hekimliği; Diş Hekimliği FakültesiPurpose: This study evaluated the microhardness and surface roughness of four artificial teeth type against various beverages. Materials and Methods: Conventional acrylic resin, reinforced acrylic resin, microfiller composite resin, and nanofiller composite resin teeth were used. From each group, 10 maxillary first and second molars were immersed in 5 beverages (tea, filtered coffee, cola, cherry juice, and distilled water. The test period of 24 hours appears comparable to approximately 1 month of normal beverage consumption. The test periods used in this study were arranged according to this protocol and 1 week, 1 month, 3 months and 6 months of normal beverage consumptions were simulated. Vickers microhardness and surface roughness of denture teeth were measured for each test period. Results: The microhardness values significantly decreased in all beverages especially in 6th month. The surface roughness values significantly increased in all beverages especially in 3th month. There were no statistically significant differences between the beverages. Microfiller composite resin denture teeth had the highest microhardness values and the lowest surface roughness values. Conclusions: Different types of beverages consumed daily negatively affect the microhardness and surface roughness of artificial teeth. Microfiller composite resin teeth could have the ideal surface properties.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 bases
