(2016) Gokcen, Esra Yesiloz; Oz, Firdevs Tulga; Ozcelik, Berrin; Orhan, Ayse Isil; Ozgul, Betul Memis; 0000-0002-3291-6174
In recent years, different biotechnological materials and modalities with antibacterial activity are being developed for oral cavity disinfection. However, the antimicrobial effects of all these materials have not been studied and understood in detail. Thus, the aim of this study was to compare the antibacterial activity of ozone therapy with dentine-bonding agents (containing antibacterial monomer 12-meth-acryloyloxydodecylpyridinium bromide (MDPB) and 10-methacryloyloxydecyl dihydrogen phosphate (MDP) and Ca(OH)(2) for deciduous teeth in vitro. The antibacterial effectiveness of the studied materials was determined by using a tooth cavity model on cylindrical cavities created in 90 deciduous second mandibular molars. Streptococcus mutans suspension was inoculated in the cavities. The teeth were distributed into six study groups (five different modalities and a negative control group). Dentine samples, which were collected from the cavities before and after the treatment sessions, were microbiologically evaluated and the materials' antibacterial activities were compared. There were statistically significiant differences in the S. mutans counts before and after treatment (P < 0.05). In terms of antibacterial efficiency, 60-second O-3 treatment was found to be the most successful method, followed by 30-second O-3, Clearfil Protect Bond (containing MDPB), Clearfil SE Bond (containing MDP) and Ca(OH)(2) treatment. The results from this study suggested that longer exposure to ozone might have more beneficial effects in terms of antibacterial activity for reducing the levels of S.mutans.
Attitudes and emotional status of parents regarding traumatic dental injuries
(2023) Uyar, Didem Sakaryali; Uyar, Tansel; Ozgul, Betul Memis; 36264041
Background/Aims Traumatic dental injuries have different effects on children and their parents, depending on the type of trauma and whether it is in primary or permanent teeth. Parents do not always seek immediate intervention for their children after each traumatic dental injury unless accompanied by conditions such as pain or bleeding that will increase emotional stress. The aim of this study was to evaluate the emotional status of parents and parents' attitudes toward urgent intervention for different traumatic dental injuries in both primary and permanent teeth. Material and Methods A questionnaire consisting of two parts was designed with a reliability coefficient of 0.87 according to the results of a pilot study. The questionnaire was sent to parents as a Google Form via online communication methods such as WhatsApp and e-mail. The first part included questions about the demographic data of the parents and children, and the second part consisted of images of traumatic dental injuries of primary and permanent teeth with questions to evaluate the emotional state of the parents and awareness of the necessity for urgent intervention. The Visual Analog Scale (VAS) was used to evaluate the emotional state, and "Absolutely yes;" "Yes;" "I don't have an idea;" "No;" and "Absolutely no" statements were used to evaluate parents' attitudes about urgent intervention. Categorical variables were shown as numbers and percentages and analyzed with Pearson chi-square. Statistical significance was evaluated for p < .05, and correlations between variables were calculated with Pearson correlation. Results The survey was completed by 845 parents. All traumatic injuries except extrusion (p = .202; p >= .05) had statistically different VAS scores for primary and permanent teeth (p < .05). Parents' attitudes for urgent intervention were statistically significant for all traumatic injuries (p < .05) except 4-mm intrusion (p = .062; p >= .05), alveolar fracture (p = .282; p >= .05), complicated crown fracture (p = .136; p >= .05), and non-traumatized healthy teeth (p = .110; p >= .05). Conclusions Traumatic dental injuries with excessive bleeding or tissue loss affect the emotional status of parents more than simple injuries, and they prefer to refer to dentists immediately. Parents responded with higher VAS scores and stronger desires for urgent intervention for permanent teeth injuries compared with primary teeth injuries which shows that parents still do not care about primary teeth as much as permanent teeth.
Does MIH Affects Preoperative and Intraoperative Hypersensitivity?
(2022) Ozgul, Betul Memis; Sakaryali, Didem; Tirali, Resmiye Ebru; Cehreli, Sevi Burcak; 35830629
Objective: Hypersensitivity is an important problem that is encountered during the treatment of hypomineralized teeth. The aim of this prospective study was to compare responses to electrical pulp tests (EPTs) and cold tests among carious teeth with and without molar incisor hypomineralization (MIH) before and after the administration of local anesthesia for caries removal Results: The EPT results of anesthetized carious teeth without MIH were significantly higher than those of carious teeth with MIH (p = 0.011). The cold test results were significantly higher for anesthetized carious teeth with MIH than for those without MIH (p = 0.0001). Intraoperative pain was significantly higher for carious teeth with MIH (p = 0.003). Conclusions: The results of this study suggest that even after achieving sufficient anesthesia, hypersensitivity remains a clinical problem in MIH-affected carious molars. The results presented in this study indicate that this phenomenon is not related to achieving effective local anesthesia; therefore, behavior management in such cases is of the utmost importance compared to relying on adjacent anesthetic methods.

(2016) Ozgul, Betul Memis; Tirali, R. Ebru; Cehreli, S. Burcak; https://orcid.org/0000-0001-6487-3984; 27295863; AAZ-1977-2021; AAD-2907-2020; AAD-6138-2021
Purpose: To compare the effects of two materials, Biodentine and conventional glass-ionomer cement (CGIC), on secondary caries formation around restorations when used as a dentin replacement material. Methods: 30 approximal cavities were prepared on mesial and distal surfaces of 15 caries-free human premolar teeth extracted for orthodontic or periodontal reasons. Cavities were filled with A: Biodentine as a base + Filtek Z250 composite (n = 15) or B: CGIC as a base + Filtek Z250 composite (n= 15). The materials were applied according to the manufacturers' instructions. Teeth were thermocycled, and placed in a demineralizing solution for 5 weeks. Secondary caries formation was assessed using the International Caries Detection and Assessment System (ICDAS) II and quantitative computer aided image measurement of caries depth. Results: The computer-aided measurements showed that the Biodentine group had significantly lower lesion depth measurements than the CGIC group (P = 0.004). However, there was no significant difference among the groups based on the ICDAS II scores (P > 0.05).
Efficacy of oil pulling therapy with coconut oil on four-day supragingival plaque growth: A randomized crossover clinical trial
(2019) Sezgin, Yasemin; Ozgul, Betul Memis; Alptekin, Nilgun Ozlem; 0000-0003-4104-6462; 31780023; AAC-5931-2020; G-1816-2014
Objectives: The aim of this study was to evaluate the plaque-inhibiting effects of oil pulling using 4- day plaque regrowth study model compared to 0.2% chlorhexidine gluconate (CHX) containing mouthrinse. Design: The study was an observer-masked, randomized, cross-over design clinical trial, involving 29 volunteers to compare 0.2% CHX and oil pulling therapy in a 4- day plaque regrowth model. After the preparatory period, in which the subjects received professional prophylaxis, the subjects commenced rinsing with their allocated rinsed. On day 5 plaque index (PI), gingival index (GI), stain index (SI), bleeding on probing (BOP) were recorded from the subjects. Each participant underwent a 14- day wash out period and then used the other mouthrinse for four days. Results: Oil pulling therapy presented similar inhibitory activity on plaque regrowth compared with CHX (PI = 1.67 +/- 0.24, 1.61 +/- 0.20, respectively) with less staining (SI = 0.21 +/- 0.13, 0.47 +/- 0.27, respectively). In addition, GI and BOP was similar in both groups (p > 0.05). Conclusion: Oil pulling with coconut oil seems to have similar plaque inhibition activity as CHX. In addition it caused less tooth staining than CHX. These findings suggest that oil pulling therapy may be an alternative to CHX rinse.

(2021) Uyar, Didem Sakaryali; Ozgul, Betul Memis; Tirali, Resmiye Ebru
The objective of this study was to evaluate inhibition efficiencies of different fluoride-free remineralization agents against erosive challenge of orange juice on primary and permanent teeth samples using optical profilometer and scanning electron microscope. Forty-five non-carious permanent third molar teeth extracted in the orthodontic treatment and 45 non-carious primary teeth extracted at the exfoliation time were included in the study. After surface preparation for each sample, three different toothpastes which included CPP-ACP (Group-1), organic calendula-xylitol (Group-2), and calcium hydroxyapatite-silica (Group-3), were applied during erosion cycle with orange juice. After the cycle, surface depth and roughness for all samples were evaluated by optical profilometer. According to the analysis of exhibited data, significance level was accepted as p<0.05. Linear surface depth values were significantly higher in permanent teeth compared to primary teeth for Group-1. However, volumetric surface roughness values were statistically higher in Group-2 and Group-3 for primary teeth compared to permanent teeth samples. Erosion inhibition efficiency of fluoride is known. However, parents are very concerned about the toxic nature and prefer using fluoride-free toothpastes. Based on the findings, parents should be informed about insufficient erosion inhibition efficiency of these fluoride-free toothpastes and further studies are needed to inform dentists about the remineralization efficiency of ingredients of toothpastes for both primary and permanent teeth.
Root Canal Filling in Primary Molars Without Successors: Mineral Trioxide Aggregate Versus Gutta-Percha/AH-Plus
(2016) Bezgin, Tugba; Ozgul, Betul Memis; Arikan, Volkan; Sari, Saziye; https://orcid.org/0000-0002-3291-6174; 26534871; AAZ-1977-2021
The aim of this study was to compare the clinical and radiographical success of mineral trioxide aggregate (MTA) and gutta-percha/AH-Plus used as a root canal filling material in primary second molars without successors. A total of 16 patients (9 girls, 7 boys) aged 6-13 years (mean: 10.5) were selected and randomly distributed into the treatment groups. Children were recalled for clinical and radiographic examination at 6, 12, 18, 24 and 36 months. Differences in treatment outcomes were analysed using chi-squared and Fisher's exact tests. Clinically, there was no significant difference in the success rates between the groups at the end of a 3-year follow-up period (MTA: 100%; Gutta-percha/AH-Plus: 70%) (P > 0.05). However, radiographically, there was a significant difference between the groups (MTA: 80%; gutta-percha/AH-Plus: 300%) (P < 0.05). The present study showed that MTA can be recommended for use in root canal treatment of primary molars without successors based on better radiographic success.
