(Bmc, 2025) Karayurek, Fatih; Altindal, Dicle; Karayurek, Erva; Gulses, Aydin
BackgroundThe cross-sectional study aimed to compare and evaluate the conversion rates of theses and dissertations of Ph.D. and specialization programs of the periodontology department in T & uuml;rkiye.MethodsA total of 789 theses of dentists who successfully graduated from higher education institutions in T & uuml;rkiye between 2001 and 2020 and qualified to become specialist dentists were analyzed. In these analyses, after descriptive information, the status of the theses converted into publications, the duration of publication, the number of citations, the indexes of the journals, and the employment status of dentists in the academy after graduation were evaluated. The Shapiro-Wilks test and Kolmogorov-Smirnov test were applied for the normality test. A chi-square test was used for categorical variables. Independent T-test, Mann-Whitney U test, Kruskal-Wallis test, and time series linear regression test were applied.Results336 Ph.D. (60.54%) and 110 (47%) dentists in specialty programs had their theses translated for publication (p = 0.001). 242 Ph.D. dentists (72.02%) published their thesis in an SCI-Expanded journal, while only sixty-nine specialty dentists (62.7%) published in these journals (p = 0.001). The publications of dentists with Ph.D. in SCI-Expanded indexed journals were mostly in journals ranked Q1 and Q2, while those of dentists with specialization were in journals ranked Q3 and Q4 (p = 0.012). The publications of dentists with Ph.D. received an average of 24 citations on the Web of Science, while those of specialists received seven (p = 0.001).ConclusionsThe decline in the conversion of the theses of dentists graduating from the specialty program into publications may impact the field of periodontology in T & uuml;rkiye. More comprehensive studies are needed to evaluate the effectiveness of the specialty program.

Clinical and Radiographic Evaluation of the Use of Prf, Cgf, and Autogenous Bone in the Treatment of Periodontal Intrabony Defects: Treatment of Periodontal Defect by Using Autologous Products
(Wiley, 2024) Alshujaa, Basem; Talmac, Ahmet Cemil; Altindal, Dicle; Alsafadi, Anas; Ertugrul, Abdullah Seckin
Background: The purpose of this randomized clinical study was to clinically evaluate and compare the efficiencies of platelet-rich fibrin (PRF), concentrated growth factor (CGF) and autogenous bone graft (ABG) in the treatment of intrabony pockets and to assess the alveolar bone gain (AB gain) radiographically (panoramic and CBCT images).Methods: Eighty intrabony pockets were divided into four groups: ojnly open flap debridement (OFD), OFD+PRF, OFD+CGF and OFD+ABG; each group consisted of 20 defects. Plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and tooth mobility (TM) by using Periotest M device were evaluated. Radiographic images were also taken to evaluate the AB gain. PRF was produced using a protocol of 2,700 RPM for 12 min and the relative centrifugal force (RCF) was evaluated. CGF was prepared as follows: 2 min 2700 rpm, 4 min 2400 rpm, 4 min 2700 rpm, 3 min 3000 rpm.Results: The study results revealed a similar improvement in PI and GI values in all groups (p > 0.05). There was a statistically significant decrease in PD and CAL in favor of ABG group at day 180 in comparison with other groups (p = 0.001). There was also a statistically significant decrease in TM and alveolar bone height loss (ABHL), whereby the AB gain gradually increased among the groups with the best group being ABG, followed by CGF, PRF, and control groups, respectively (p = 0.001).Conclusions: The study results support the treatment of periodontal intrabony pockets using OFD in combination with ABG, CGF, and PRF, as ABG showed the best results followed by CGF and PRF.
A Comparison of the Smile Esthetic Understanding of Periodontists, Orthodontists, General Dentists, and Dental Students
(Pera Yayincilik Hizmetleri, 2024) Altindal, Dicle; Tunca, Yasemin
Objective: The aim of this study was to evaluate smile esthetics among periodontists, orthodontists, general dentists, and dental students. Methods: The study consisted of five groups: periodontists, orthodontists, general dentists, fifth-year dental students, and fourth-year dental students. The evaluators used the Smile Esthetics Index (SEI) consisting of 10 items to analyze the natural smile photographs of 15 different individuals. One-way ANOVA was performed for the comparison of group means. The Duncan multiple comparison test was also used to identify different groups. Non -linear principal component analysis was performed to determine the configuration of the relationship between categories of variables in two-dimensional space. Results: The group with the highest reliability coefficient among the groups was the fourth-year dental students (Cronbach's Alpha = 0.89). This was followed by general dentists, periodontists, fifth-year dental students, and orthodontists. According to the evaluation of the total score averages of the fifteen pictures, a statistically significant difference was observed between the groups ( p = 0.041). Accordingly, the fourth-year dental students (5.78 +/- 1 .13) had a lower total score than the fifth-year dental students (6.56 +/- 0.88), and this difference was statistically significant. However, no significant difference was observed between the fourth-year dental students and the general and specialized dentists and between the fifth-year dental students and graduated and specialized dentists in terms of the total score given to the pictures. Conclusion: It was observed that the reliability coefficient was high in all groups evaluated with SEI. It can be concluded that esthetic perception is formed by actively performing the profession of dentistry, and this situation does not change according to specialization.

(Springer Heidelberg, 2024) Altindal, Dicle; Alsafadi, Anas; Alshujaa, Basem; Talmac, Ahmet Cemil; Ege, Bilal; Calisir, Metin; Alpaslan, Nazli Zeynep
Objective The aim of this study is to evaluate the effectiveness of submucosal 8 mg (2 mL) dexamethasone (DEX) on postoperative pain, swelling, chewing efficiency, trismus, healing, and discomfort after periodontal flap surgery (PFS). Methods In this randomized controlled split-mouth study, 25 patients underwent PFS in the mandible, whereby postoperative, submucosal DEX was injected to the surgical field to the test group and submucosal normal saline was applied to the control group. Pain was evaluated using the Visual Analogue Scale (VAS) and the 101-point numeric rate scale in the first 8 h after PFS and on the 2nd, 3rd, 4th, and 7th days, whereas swelling, chewing efficiency, trismus, healing, discomfort and analgesic consumption were evaluated preoperatively on the 1st, 2nd and 7th days. Results In the intergroup evaluation, the VAS-7th hour value of the test group was lower than the control group(p < 0.05). On the 1st day, it was observed that there was less swelling and more chewing efficiency in the test group than in the control group(p < 0.05). When time-dependent changes were examined, the decrease in mouth opening due to trismus in the control group was greater than that in the test group on the 1st and the 2nd days compared to the preoperative period(p < 0.05). Finally, postoperative healing, discomfort, and analgesic consumption were similar between groups. Conclusion Within the limits of this study, the submucosal DEX may be an effective protocol in the management of pain, swelling, and trismus after PFS. Clinical relevance Our findings shed light on the possible effects of DEX after PFS. Trial registration This study was registered on ClinicalTrials.gov (NCT06119893).

(Kerman Univ Medical Sciences, 2019) Yayli, Nazli Zeynep Alpaslan; Tunc, Serap Keskin; Kaki, Gulter Devrim; Altindal, Dicle
BACKGROUND AND AIM: The purpose of this study was assessing oral health status and dental anxiety differences between the freshman and senior dental students and the effect of awareness on dental practices. METHODS: Freshman (n = 71) and senior dental students (n = 41) were included in this study. All participants were applied Corah Dental Anxiety Scale (C-DAS) and asked for the frequency of dental visits in a year. Gingival index (GI), plaque index (PI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and decayed, missing, and filled teeth (DMFT) index were recorded. Number Cruncher Statistical System (NCSS) program and Shapiro-Wilk, t, Mann-Whitney U, Pearson chi-square, and Fisher-Freeman-Halton tests were used for statistical analysis (P < 0.0500). RESULTS: C-DAS score of the freshman students was found significantly higher than the senior students (P < 0.0500). There was a statistically significant difference in the frequency of dental visits between freshman and senior students (P < 0.0010). GI, PI, and BOP values of the freshman students were significantly higher than the senior students (P < 0.0010). There was no statistical differences between PD and CAL measurements (P > 0.0500). It was found that the DMFT index of freshman students was significantly higher than the senior students (P < 0.0010). CONCLUSION: This study has shown that dental anxiety decreases as awareness and consciousness increase in terms of dental practice. More anxious participants' oral health is weak, individuals with high dental anxiety make fewer visits to the dentists and need more dental practices.

(Wiley, 2023) Altindal, Dicle; Deveci, Kubra Ceran; Talmac, Ayse Gul Oner; Talmac, Ahmet Cemil; Calisir, Metin
ObjectivesBad breath is a condition that negatively affects people's social interactions and quality of life. The aim of this study was to evaluate the effect of thyme mouthwash on intraoral halitosis, gingival index (GI) and plaque index (PI) in patients with gingivitis. MethodsIn this retrospective study, 60 gingivitis patients (30 women/30 men) received initial periodontal treatment followed by oral hygiene instructions (OHI) and then were divided into four groups: The control group (C) received only OHI, while chlorhexidine (CHX) mouthwash was prescribed to the CHX group, Zinc acetate and CHX diacetate mouthwash was prescribed to the zinc acetate and CHX diacetate (ZnA) group, and the thyme (T) group was instructed to use thyme mouthwash. GI, PI and volatile sulfur compound (VSC) values were recorded at baseline and at the first week of treatment. ResultsThe initial values of the recorded parameters did not differ significantly between the groups. In all groups, VSCs, GI and PI decreased after treatment (p = 0.001). There was no significant difference between the PI values of the groups after treatment (p = 0.188). On the contrary, the GI and VSC values after treatment were significantly different between the groups (p = 0.001). GI values were highest in the control group and lowest in the CHX group. In terms of VSCs, a significant difference was found between groups T and C, and between groups T and ZnA (p = 0.001). ConclusionThis study showed that the use of thyme mouthwash after periodontal treatment was effective in improving bad breath and gingivitis in gingivitis patients.
Erbium, Chromium-Doped: Yttrium, Scandium, Gallium, Garnet and Diode Lasers in the Treatment of Peri-Implantitis: Clinical and Biochemical Outcomes in a Randomized-Controlled Clinical Trial
(Springer London Ltd, 2022) Alpaslan Yayli, Nazli Zeynep; Talmac, Ahmet Cemil; Keskin Tunc, Serap; Akbal, Damla; Altindal, Dicle; Ertugrul, Abdullah Seckin
This study aims to evaluate the effects of 940 nm diode laser and 2780 nm erbium, chromium-doped: yttrium, scandium, gallium, garnet (Er,Cr:YSGG) laser used in addition to mechanical therapy in the non-surgical treatment of peri-implantitis on clinical parameters and matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) levels in the peri-implant crevicular fluid. A total of 50 patients with peri-implantitis were randomized into three groups to receive peri-implant treatment. The control group (n = 17) only received conventional non-surgical mechanical therapy. The trial groups [(diode group (n = 16) and Er,Cr:YSGG group (n = 17)] received dental laser in addition to mechanical therapy. Gingival index (GI), plaque index (PI), bleeding on probing, probing depth (PD), MMP-9, and TIMP-1 levels were assessed at baseline (T0) and at 6 months after treatment (T1). The GI, PI, and PD significantly decreased in all groups at T1, compared to T0 (p < 0.05). The decrease in the PD was similar between the control and diode groups with Er,Cr:YSGG providing more reduction (1.16 +/- 0.64 mm) than either method (p = 0.032). A significant intra-group decrease in MMP-9 level was only observed in the Er,Cr:YSGG group (p = 0.009). The decrease in TIMP-1 level from T0 to T1 was similar between the control and the diode groups (p > 0.05) and it was significantly lower than the decrease in the Er,Cr:YSGG group (p < 0.05). Addition of diode laser to non-surgical mechanical therapy does not provide any additional benefit for treatment outcomes. The Er,Cr:YSGG laser seems to be more efficient both at clinical and molecular levels.

(Springer London Ltd, 2020) Aydinyurt, Hacer Sahin; Akbal, Damla; Altindal, Dicle; Bozoglan, Alihan; Ertugrul, Abdullah Seckin; Demir, Halit
Background Recent studies reported that hyaluronic acid (HA) has anti-inflammatory, anti-edematous, and anti-bacterial activities in dentistry, particularly in gingival disorders caused by subgingival plaque microorganisms. Aims This study aimed to evaluate the early term effects of HA as an adjunct to scaling and root planing (SRP) on clinical parameters, periodontal inflamed surface area (PISA), and adenosine deaminase (ADA), catalase (CAT), and glutathione (GSH) levels in gingival crevicular fluid (GCF) in periodontitis. Methods A total of 24 periodontitis patients per group were included in this randomized-controlled study. The study population was divided into four groups: in Group 1: SRP+ saline; in Group 2: SRP + HA gel; in Group 3: SRP+ HA mouth rinse; and in Group 4: SRP + HA mouth rinse + HA gingival gel were applied. At baseline and week 4, clinical parameters and PISA were calculated. Also, biochemicals' (ADA, CAT, and GSH) levels were determined by spectrophotometric analysis. Results There was a statistically significant improvement in clinical parameters and PISA in all four groups in control sessions (p < 0.05). There was a significant decrease in ADA in GCF and significant increases in CAT and GSH levels after SRP (p < 0.05) in all four groups. The groups that were administered only gel (2nd and 4th) were different from other groups in terms of ADA, CAT, and GSH levels at 1st week (p < 0.05). Conclusion HA application as an adjunct to SRP did not affect the clinical results, although, in the control sessions following the application, the results were favorable for the biochemical data in gel-applied groups.
Evaluation of Il-8 and Il-6 Levels in Gingival Crevicular Fluid of Individuals Undergoing Clear Aligner Therapy
(E H Angle Education Research Foundation, inc, 2025) Altindal, Dicle; Tunca, Yasemin; Tunca, Murat
Objectives: To compare short-term changes in the levels of interleukin-8 (IL-8) and interleukin-6 (IL-6) in the gingival crevicular fluid (GCF) of individuals undergoing orthodontic treatment with clear aligners. Materials and Methods: This study included 15 individuals. Each patient used clear aligners designed not to cause tooth movement in the GCF sampled teeth, to be changed every 10 days. GCF samples were collected from teeth 16 (upper right first molar) and 31 (lower left central incisor) at baseline and after the procedure at the first hour, third, seventh, 14th, and 21st days. In addition, clinical periodontal parameters for the full mouth and the teeth from which GCF was collected were recorded initially and on the 21st day. Results: A statistically significant difference was observed between the levels of IL-8 before the procedure, on the third and seventh days, and on the 21st day (P < .01). The increase in IL-6 levels on the 14th and 21st days was significantly different compared to the levels before the procedure (P < .01). A positive correlation was detected between IL-8 and IL-6 levels at the first hour, a negative correlation on the third day, and a lower level of positive correlation on the seventh, 14th, and 21st days. Conclusions: Within 21 days, the levels of IL-8 and IL-6 significantly increased in individuals undergoing orthodontic treatment with clear aligners. Within the limits of this study, the clear aligner material may affect the levels of IL-8 and IL-6 in the GCF.
Evaluation of Knowledge About and Attitudes Towards Toothbrush Disinfection, Personal Plaque Control, and Periodontal Diseases of Patients Presenting To Dental Clinics
(Wiley, 2023) Altindal, Dicle; Aydinyurt, Hacer Sahin; Yalcin, Duygu Korkmaz
Objectives The present study aims to evaluate patients' knowledge about toothbrush disinfection (TBD), plaque control, knowledge, and awareness of periodontal diseases (P-knowledge and P-awareness). Methods The study enrolled 121 participants (70 women and 51 men). Participants were asked to fill out a survey containing questions about demographic characteristics, toothbrushing habits, toothbrush storage conditions, toothpaste use, TBD, P-knowledge, and P-awareness. The periodontal clinical parameters (GI, PI, PPD, CAL, BOP, and GR) and DMFT index were recorded. The patients were informed about TBD, and 1 month later, the participants were contacted again and asked whether they disinfected their toothbrushes. Results The participants (51.2%) do not have any knowledge about TBD. Most of those who reported disinfecting their toothbrushes think that washing toothbrushes with tap water is disinfection (23.1%). One month after the TBD training, only 36.3% of the participants reported that they disinfected, albeit not regularly, their toothbrushes with white vinegar. While there was no statistically significant relationship between genders in terms of visiting dentists, a significant relationship was found between genders in terms of toothbrushing frequency (p < 0.05). P-awareness was found to be "medium" while P-knowledge was at a "low" level. While there was no statistically significant difference between income levels in terms of P-knowledge levels, a significant difference was found between genders and educational backgrounds in terms of P-knowledge levels (p < 0.05). Conclusions The results of the study suggest that the participants do not have enough knowledge about toothbrush storage conditions, toothpaste sharing, and TBD. Collaborating with dental hygienists to raise awareness about oral health and TBD may have a positive impact.

(Kerman Univ Medical Sciences, 2023) Altindal, Dicle; Kaya, Filiz Acun; Yildirim, Tuba Talo; Uysal, Ersin; Duger, Nurullah
Objective: The aim of this study was to evaluate the anxiety levels of orthodontic patients during the 1-year period in the ongoing pandemic. Methods: The study included patients between the ages of 12 and 30 years and who were continuing their fixed orthodontic treatment at Ad & imath;yaman University, Faculty of Dentistry, Department of Orthodontics and filled out the State-Trait Anxiety Inventory. A total of 266 patients filled out the questionnaire at their first clinical visit between June 8 and July 8, 2020 (T0) and 176 of 190 patients (response rate: 92.63%) that were still under treatment filled out the questionnaire for a second time between June 15 and July 16, 2021 (T1). Results: In the total population, there was a significant decrease in the State-Trait Anxiety Inventory-S score (P < .05), while there was no significant change in the State-Trait Anxiety Inventory-T score (P > .05). Anxiety scores were significantly higher in women and individuals aged over 18 years at T0 (P < .05), whereas only the anxiety scores of individuals aged over 18 years were significantly higher in T1 than in individuals aged below 18 years (P < .05). The State-Trait Anxiety Inventory-S score showed a significant decrease at T1 compared to T0 for female patients (36.02 +/- 11.32 vs. 38.82 +/- 9.84) and patients aged under 18 years (34.26 +/- 9.54 vs. 36.85 +/- 9.26) (P < .05). Conclusion: The state anxiety levels of orthodontic patients decreased during the 1-year period of the pandemic, while there was no significant change in their trait anxiety levels.
Evaluation of the Effect of Er,cr:ysgg Laser Application on Peri-Implant Crevicular Fluid Receptor Activator of Nuclear Factor-Kappa B Ligand and Osteoprotegerin Levels in the Non-Surgical Treatment of Peri-Implantitis: a Randomized Clinical Trial
(Wiley, 2024) Alpaslan, Nazli Zeynep; Altindal, Dicle; Akbal, Damla; Talmac, Ahmet Cemil; Tunc, Serap Keskin; Ertugrul, Abdullah Seckin
Background: This study aimed to investigate the effect of erbium, chromium doped:yttrium,scandium,gallium,garnet (Er,Cr:YSGG) laser application combined with non-surgical mechanical debridement (MD) on clinical parameters and peri-implant crevicular fluid receptor activator of nuclear factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) levels in the treatment of peri-implantitis. Methods: A total of 49 patients who underwent non-surgical treatment of peri-implantitis were randomly divided into two groups. The control group (n = 26) received MD alone, while the laser group (n = 23) received MD+Er,Cr:YSGG. The clinical parameters (bleeding on probing [BoP], gingival index [GI], plaque index [PI], probing depth [PD]), marginal bone loss (MBL), and biochemical parameters (RANKL and OPG) were measured at baseline (T0) and 6 months after treatment (T1). Results: There was a statistically significant decrease in all the clinical parameters in both groups at T1 compared to T0 (p < 0.05). The BoP, PD, MBL, and RANKL reductions were significantly higher in the laser group than in the control group (p = 0.046, p = 0.014, p = 0.047, p = 0.045, respectively). The OPG levels significantly increased at T1 in the laser group (p = 0.01). The OPG/RANKL ratio increased significantly in both groups at T1, which favored the laser group (p = 0.034). Conclusions: Although both treatment methods were influential in treating peri-implantitis, the laser group (MD+Er,Cr:YSGG) yielded more favorable results by reducing clinical inflammation and improving biochemical parameters. Based on these findings, Er,Cr:YSGG laser may be a beneficial adjunctive treatment in this patient group.
Evaluation of the Effectiveness of Diode Laser Therapy in Conjunction With Nonsurgical Treatment of Peri-Implantitis
(Korean Acad Periodontology, 2023) Altindal, Dicle; Alkan, Eylem Ayhan; Calisir, Metin
Purpose: Peri-implantitis (PI) is an inflammatory condition associated with the destruction of bone tissue around a dental implant, and diode lasers can be used to treat this disease. In this study, we aimed to evaluate the effectiveness of a 940-nm diode laser for the nonsurgical treatment of PI. Methods: Twenty patients (8 women and 12 men) were enrolled in a split-mouth randomized controlled study. In the control group (CG), mechanical debridement with titanium curettes accompanied by airflow was performed around the implants. The test group (TG) was treated similarly, but with the use of a diode laser. Clinical measurements (plaque index, gingival index [GI], probing pocket depth [PPD], bleeding on probing [BOP], clinical attachment level, and interleukin-1 beta [IL-1 beta] in the peri-implant crevicular fluid) were evaluated and recorded at baseline and 3 months. IL-1 beta levels were determined using the enzyme-linked immunosorbent assay method. Results: The symptoms were alleviated in both groups at 3 months as assessed through clinical measurements. GI, BOP, and PPD were significantly lower in the TG than in the CG (P<0.05). The IL-1 beta level increased post-treatment in both groups, but this increase was only statistically significant (P<0.05) in the CG. Conclusions: The diode laser enabled improvements in clinical parameters in the peri-implant tissue. However, it did not reduce IL-1 beta levels after treatment. Further studies about the use of diode lasers in the treatment of PI will be necessary to evaluate the effects of diode lasers in PI treatment.
