Two Different Approaches In Three-Dimensional Planning Of Orthognathic Surgery: Surgery First And Traditional Orthognathic Surgery
(Kapadokya Üniversitesi Yayınları, 2024) Rübendiz, Meliha; Kadıoğlu, Merve Berika; Kurt, Ezgi
In individuals with completed growth development and Class III ma-locclusion, orthognathic surgery is inevitable for achieving ideal occlusion and facial aesthetics. In the treatment of orthognathic surgery, it has been a long-standing approach to plan orthognathic surgery using traditional two-dimensi-onal cephalometric planning and model surgery after fixed orthodontic treat-ment, which allows for the decompensation of malocclusion to improve skeletal correction and position of the teeth ideally.
Assessment of Facial Depth in Skeletal Class III Cases with Mandibular Prognathism: A Cephalometric Study
(Kapadokya Üniversitesi Yayınları, 2024) Örsçelik, Ragıp Burak; Mermut Gökçe, Sıla; Oral, Neşe
Statement of the problem: In patients with mandibular prognathism and skeletal Class III malocclusion, there is a lack of data regarding the relati-onship between average facial depth and anterior facial height. Objective: This study aims to determine the average facial depth in pa-tients with mandibular-origin skeletal Class III malocclusion and to investigate the relationship between this measurement and anterior facial height. Materials and Methods: A total of 626 individuals with Class III malocc-lusion were included in the study (292 females, 335 males). On cephalometric radiographs of the participants, the pogonion (Po), nasion (N), Frankfort Hori-zontal plane (FH), condylion (Co), and menton (Me) points were marked. The anterior facial height of the patients was calculated, and all participants were divided into three groups: long, average, and short. The distance where Co and N intersected the FH was defined as the 'facial depth distance' (Co-N). Finally, the ratio of the facial depth distance (Co-N) to the anterior facial height (N-Me) was calculated. Results: A significant difference was observed in the mean ratio of Co'-N' to N-Me between long-faced individuals and short-faced individuals (P < 0.05). The ratio of the facial depth distance (Co'-N') to the anterior facial height (N-Me) was found to be 69% ± 5. This ratio was determined to be 68% ± 4 in long-faced individuals, 69% ± 4 in average-faced individuals, and 72% ± 5 in short-faced individuals. Conclusions: The ratio between Co-N and N-Me may provide a new perspective in the evaluation of mandibular-origin Class III malocclusions.
Evaluation of Facial Depth in Skeletal Class II Cases of Maxillary Origin: A Cephalometric Analysis
(Kapadokya Üniversitesi Yayınları, 2024) Gider, İsmail Korhan; Ölmez, Hüseyin; Örsçelik, Ragıp Burak
Statement of the problem: The literature currently lacks sufficient data on the correlation between the average facial depth distance and its relationship with the anterior facial height in individuals presenting with skeletal Class II malocclusion of maxillary origin. Objective: This study aims to examine the extent of average facial depth in individuals with maxillary-based Class II malocclusion and to assess the cor-relation between average facial depth and anterior facial height. Materials and Methods: The study included 712 individuals with Class III malocclusion, with 361 being female and 351 male. Cephalometric radiog-raphs of the participants were used to identify the pogonion (Po), nasion (N), Frankfort Horizontal plane (FH), condylion (Co), and menton (Me) points. The distance from point Co projected onto the FH plane to point N (Co'-N') was determined as the facial depth distance, while the distance between points N and Me was considered the anterior facial height distance. Subsequently, the facial depth distances of all individuals were measured and ratioed with the anterior facial height distance to establish standardized ratios for maxillary-ba-sed Class II cases. Results: The mean facial depth measurement (Co?-N?) is 86±5mm, with a corresponding ratio to the anterior facial height (N-Me) of 69±5%. When cate-gorized by facial morphology, this ratio was determined to be 67±4% for indi-viduals with longer faces, 68±4% for those with average facial lengths, and 70±5% for individuals with shorter facial lengths. Conclusions: Utilizing the Co?-N?/N-Me ratio in cephalometric analysis could provide a fresh perspective on evaluating skeletal Class II malocclusions arising from maxillary development.
Evaluation of Facial Depth in Maxillary-Based Class III Individuals: A Cephalometric Study
(Kapadokya Üniversitesi Yayınları, 2024) Koç, Fırat; Sağdıç, Deniz; Örsçelik, Ragıp Burak
Statement of the problem: There is a lack of data in the literature regar-ding the relationship between the average facial depth distance and this dis-tance with the anterior facial height in patients exhibiting skeletal class III ma-locclusion originating from the maxilla. Objective: The aim of this study is to investigate the amount of average facial depth in maxillary-based Class III cases and to evaluate the relationship between average facial depth and anterior facial height. Materials and Methods: The study comprised 592 individuals diagno-sed with Class III malocclusion, of whom 281 were female and 311 were male. The pogonion (Po), nasion (N), Frankfort Horizontal plane (FH), condylion (Co), and menton (Me) points were marked on the cephalometric radiographs of the participants. The projection of point Co to point N on the FH plane (Co'-N') was defined as the facial depth distance, while the distance between N and Me was determined as the anterior facial height distance. Subsequently, the fa-cial depth distances of all individuals were measured. The facial depth distance was then ratioed with the anterior facial height distance in an attempt to reach standard ratios for maxillary-based Class III cases. Results: Average facial depth distance (Co?-N?) is 83 ± 7 mm. The ratio of facial depth distance (Co?-N?) to anterior facial height (N-Me) (Co?-N?/N-Me) is determined to be 68 ± 5%.-When this ratio is evaluated separately according to facial heights; it is determined as 66 ± 4% in long-faced individuals, 67 ± 4% in normal-faced individuals, and 71 ± 5% in short-faced individuals. Conclusions: The use of this ratio in cephalometric film analysis may bring a new perspective to the evaluation of maxillary Class III malocclusions.

(Kapadokya Üniversitesi Yayınları, 2024) Kottaş, Bilgehan; Ahmad, Melika; Akdoğan, Semih; Savaş, Abdulhaluk; Yılmaz Savaş, Tuba
Statement of the problem: Studies are ongoing to enhance the bonding strength between glass ceramic restorations and resin cements. The effect of va-rious drying methods on bonding strength is still controversial. Objective: The aim of this study is to determine whether different drying methods and durations affect the bonding strength between leucite re-inforced glass ceramics and resin cement. Materials and Methods: Thirty different leucite reinforced glass ceramic (G-Ceram, Atlas Enta) specimens were divided into 5 groups. All specimens were treated with 5% hydrofluoric acid (HF) (IPS Ceramic Etching Gel, for 60 seconds according to the manufacturer's instructions. After acid etching, speci-mens were rinsed with water spray for the duration of acid etching and dried with pressurized air. Following the application of primer (Monobond N, Ivoclar Vivadent), specimens were divided into 5 groups based on air-drying methods and durations: Control (C) group (dried with pressurized air for 10 seconds; air drying in ceramic furnace for 30 seconds (CF30); air drying in ceramic furnace for 60 seconds (CF60); air drying with a hair dryer for 30 seconds (HD30); air drying with a hair dryer for 60 seconds (HD60). Ceramic specimens were bon-ded with dual cure resin cement (Multilink N; Ivoclar Vivadent) using a split Teflon mold with a diameter of 2.5 mm. Force was applied to the specimens with a 1 mm/min speed using a chisel-shaped applicator tip until failure occur-red. The results were analyzed using one-way ANOVA followed by Tukey's post hoc test within the 95% confidence interval. Results: There was a significant difference among the mean bond strength values of the groups (P<0.05). Group CF60 and Group HD60 both exhi-bited significantly higher mean shear bond strength values compared with the group C (P<0.05). Group CF30 and Group HD30 showed similar bonding values with CF60, HD60 and C groups (P>0.05).Conclusions: Drying the primer with ceramic furnace or the hair dryer for 60 seconds significantly enhanced the bonding strength between the leucite-reinforced glass ceramic and resin cement.
COVID-19 and Oral and Maxillofacial Imaging and COVID-19 Oral and Maxillofacial Radiology
(Kapadokya Üniversitesi Yayınları, 2023) Verner, Francielle Silvestre; Kamburoğlu, Kıvanç
Oral and Maxillofacial Radiology (OMFR) Clinics, private or at Dental Schools, represent a potential environment for transmission and cross-infec-tion of coronavirus disease 2019 (COVID-19). During OMFR procedures, such as intra- or extraoral imaging examinations, cone-beam computed tomogra-phy, and ultrasonography, the dental staff is in direct contact with patients, increasing the risk of disease transmission. Thus, new biosafety protocols had to be adopted. Due to the high transmissibility of SARS-CoV-2 highly restric-tive measures were imposed, and social distance was the main one. In this scenario, teleradiology was encouraged to reduce contamination and protect radiologists, and dental schools had to take strict precautions in their tradi-tional educational system. Considering recent literature regarding OMFR and COVID-19, this review provides substantial data about the new precautions of biosafety, teleradiology, and the impact on OMFR teaching.

(Kapadokya Üniversitesi Yayınları, 2023) Ozer, Nazire Esra
Statement of the problem: To help physicians choose the right materials for treatment planning, it is necessary to investigate to the mechanical and physical characteristics of denture teeth made with new technology. Objective: This study aims to investigate the comparative microhard-ness of artificial teeth with different composition. Materials & Methods: A total of 96 specimens (n=32) were prepared us-ing three different types of artificial teeth (conventional polymethylmethacry-late, , and nanohybrid composite) (Group CA - Conventional PMMA, Group IS - Isosite Group DCL - double cross-linked acrylic). Surface hardness values were determined using a microhardness tester (Shimadzu HMV Corporation, Tokyo, Japan) with a load of 500 g and a dwell time of 15 seconds. Three inden-tations were obtained for each sample and the Vickers Hardness Number (VHN) was calculated and averaged. One-way analysis of variance (ANOVA) and post-hoc Tukey HSD tests were used for statistical analysis. The statistical significance level of the data was taken as ?=0.05. Results: The highest microhardness values were observed in Group IS (53.96 ± 8.5 VHN) and the lowest in Group CA (53.55±9.9 VHN). However, no statistically significant difference was found between the groups (P>0.05). Conclusions: For the durability and function of prosthetic rehabilita-tions performed by clinicians, the choice of artificial teeth should not be ig-nored, based on cost and accessibility criteria.
Influence of Composition and Thickness on The Color and Translucency of Glass-Ceramic Materials for Laminate Veneer Restorations: An In Vitro study
(Kapadokya Üniversitesi Yayınları, 2023) Yılmaz Savaş, Tuba; Yıldızlar, Seda
Statement of the problem: Numerous glass-ceramic materials are com-mercially available, yet achieving optimal esthetic results relies significantly on material composition and thickness. The selection of suitable material and thickness poses an ongoing challenge in clinical practice. Objective: This study aimed to investigate the effect of the composition and thickness of different glass-ceramic materials on the Commission Interna-tionale de l'éclairage (CIE) L*, a*, and b* color coordinates and the translucency parameter (TP00). Materials & Methods: Glass-ceramic blocks of A2 shade, with low translucency, encompassing feldspathic (FS), leucite-reinforced feldspathic (LR), and lithium-disilicate (LD) compositions, were sectioned into three thick-nesses: 0.5 mm, 0.7 mm, and 1 mm (n=10). All specimens were polished with ceramic polishing rubbers. Using a spectrophotometer, the CIE L*, a*, and b* color coordinates of the specimens were measured over gray, white, and black backgrounds. The TP00 was calculated using the CIEDE2000 color difference for-mula. The CIE L*, a*, b*, and TP00 were analyzed using two-way ANOVA and Tukey HSD post-hoc tests (?=0.05). Results: Material, thickness, and their interaction significantly influ-enced the CIE L*, a*, b*, and TP00 values (P<0.001). The LR group displayed the highest L* and a* values, while the LD group showed the lowest (P<0.001). Con-versely, the LD group exhibited the highest b* value (P<0.001). Lightness was lowest in 0.5 mm-thick specimens (P<0.001) and similar for 0.7 mm-thick and 1.0 mm-thick specimens (P>0.05). Redness and yellowness increased with in-creasing thickness (P<0.001). Regardless of thickness, the FS group had the high-est TP00 (16.32±1.54), while the LR group had the lowest TP00 (14.31±1.67). Re-gardless of material, 0.5 mm-thick specimens demonstrated significantly higher TP00 (17.49±1.10) than 0.7 mm-thick (15.45±0.83) and 1.0 mm-thick (13.11±1.12) specimens. There was no significant difference between the 0.5 mm-thick FS and LD groups (P>0.05) and 1.0 mm-thick LR and LD groups (P>0.05).

Statement of the problem: It is unclear how the success of color selection with custom shade guides is influenced by the observer's level of color education and the type of light source. Objective: The aim of this study is to compare the color matching ability under different light sources between observers with and without color education and to in-vestigate in which shade tabs they are more successful, using a custom-made shade guide. Materials & Methods: The study included 5 prosthodontists (PD), 5 general dentists (GD), 5 dental ceramists (DC), 5 removable denture technicians (RDT), and 10 participants with no color education (NP). Using dentin powder from feldspathic dental porcelain, 2 sets of 16 shade tabs matching those in the Vita Lumin Classic shade guide were produced. The Lab values of the produced shade tabs with the same shade code were measured using a colorimeter device, and those with ?E values below 0.1 were used for shade matching. Each participant conducted a total of 48 shade matches under 3 different light sources (tungsten-TG, fluorescent-FL, and D65). Results: It was found that the shade matching success of dental professionals in the PD, GD, RDT, and DC groups significantly differed from that of the participants in the NP group (?² = 23.417; P< 0.001). Shade matches conducted under the D65 light source were more successful than those under the TG and FL light sources, and par-ticipants were found to match shade tabs with higher saturation, such as A4 and C4, more successfully.

Surgical and Prosthetic Management of a Juvenile Ossifying Fibroma In a 5-Year-Old Child: A Clinical Report
(Kapadokya Üniversitesi, 2023) Pişkin, Bülent; Durmaz, Abdullah; Sipahi, Cumhur; Özarslantürk, Savaş; Şahin, Nesrin; Cüce, Ferhat
Juvenile ossifying fibroma (JOF) is a rare and benign fibro-osseous lesion of the craniofacial skeleton commonly seen in children under 15 years of age. Despite being classified as benign, JOF lesions are aggressive in nature and reach large dimensions in a short period of time. Thus, their resections may cause large orofacial defects which have serious detrimental effects on the functional and nutritional requirements of pediatric patients being in the period of growth. Therefore, its early diagnosis and proper surgical and prosthetic management are of vital importance for the survival of patients. However, no detailed reports in the literature describe the prosthetic management of large intraoral defects in pediatric patients under 10 years old.

(Kapadokya Üniversitesi, 2023) Kaplan, Melek Hilal; Erdoğan, Hilal
Statement of the problem: For successful endodontic treatment, mecha-nical cleaning and chemical irrigation can be used together. Since there is not yet a single solution sufficient for both root canal cleaning alone, combined use of irrigants is recommended for the synergistic effect. Polyhexanide (PHMB), boric acid, phytic acid, peracetic acid, and hypochlorous acid are relatively new alternative endodontic irrigation solutions and there are no studies in the lite-rature on the combined use of alternative solutions. Objective: This study aimed to evaluate the interactions that would re-sult from applying PHMB as a substitute for CHX following alternative inter-mediate irrigation solutions that might be utili-zed with NaOCl. Materials & Methods: Eight microtubes were used for this study. 0.5ml of 5%NaOCl was placed in each microtube first, the microtubes were divided into two groups as the final product CHX and Polyhexanide, and the two gro-ups were divided into four groups with different irrigants in themselves. The study was conducted at room temperature and the images of the mixtures were photographed at 1 min, 10 min, 20 min, 30 min, and 1 hour. Groups; G1: NaOCl+ 1%Phytic acid +0.1%Polyhexanide, G2: NaOCl+ 0.02%Hypochlorous acid +0.1%Polyhexanide, G3: NaOCl+ 2% Peracetic acid +0.1%Polyhexanide, G4: Na-OCl+ 5% Boric acid +0.1%Polyhexanide, G5: NaOCl+ Phytic acid+ 2%CHX, G6: NaOCl+ 0.02%Hypochlorous acid +2%CHX, G7: NaOCl+ 2% Peracetic acid+2%CHX, G8: NaOCl+ 5% Boric acid + 2%CHX. Results: White or brown precipitates occurred as soon as the solutions were applied to all of the CHX groups; milky-white precipitate was only seen in the Polyhexanide group's Phytic acid-added group. After 5 minutes, air bubbles were seen in the Polyhexanide group that had Peracetic acid added, whereas the CHX group had an increase in brown precipitates. Conclusions: Considering the current research conditions, In clinical practice, the administration of Polyhexanite as the last irrigant and the combi-nation of NaOCl with boric acid or hypochlorous acid can be advised.

(Kapadokya Üniversitesi, 2023) Öztürk, Hilal Peker; Özgedik, Hatice Seda; Avsever, İsmail Hakan; Özarslantürk, Savaş; Allaberdiyev, Merdan; Aslan Balcı, Aslıhan
Statement of the problem: It is important for oral surgeons to determine the precise location of mandibular third molar before extraction. The close rela-tionship of mandibular canal and mandibular third molar is a risk factor for alveolar nerve damage. Objective: The purpose of this study is to assess the relationship between mandibular canal and the mandibular third molar which has already been seen in close relationship on panoramic radiograph (PR) by the compari-son of findings of the cone-beam computed tomography (CBCT) and the PR. Materials & Methods: Close relationship between the mandibular third molar and mandibular canal was scanned in 180 patients by the PR. Images were also obtained by CBCT from patients among which a close-relationship was detected between mandibular canal and mandibular third molar. Results: Close relationship was detected between mandibular third mo-lar and mandibular canal on 26 of 180 PR and evaluated 46 mandibular third molars. In 41 cases, both the findings in PR and in CBCT images showed comp-liance with each other. As a result it was clearly seen that the mandibular third molars which were detected to be in close relationship on PR were mostly also in close relationship with mandibular canal on CBCT-images. Conclusions: If the close relationship is not seen on the panoramic ima-ges then there is no need to get CBCT for extracting the mandibular third mo-lars. By this way complication risks are eliminated with less radiation. However CBCT should be definitely used in cases which complete assessment cannot be made in no way due to artifacts such as superposition in PR.

(Kapadokya Üniversitesi, 2023) Yılmaz Savaş, Tuba; Şavaş, Aldulhaluk; Pişkin, Bülent
Statement of the problem: The bonding between the resin cement and zirconia still needs to be improved and the effect of the experimental acid app-lication duration on the resin bond strength with zirconia is unknown. Objective: This study aimed to investigate the effect of different acid application times on the shear bond strength between zirconia and dual-cure resin cement. Materials & Methods: A total of 50 zirconia disks were prepared in 2 mm thickness and randomly divided into five treatment groups: control (no treatment was applied), 30 seconds HF:H2O:H2O2 acid application group, 60 seconds HF:H2O:H2O2 acid application group, 90 seconds HF:H2O:H2O2 acid application group, and 120 seconds HF:H2O:H2O2 acid application group. Then a dual-cure resin cement was applied over the 3 mm diameter and 3 mm thickness of the zirconia specimens. The specimens were immersed in distilled water and maintained at a temperature of 37°C for a duration of 24 hours. The shear bond strength tests were performed using a universal testing machine with a force of 1 mm/min until the fracture occurs, and the data were analyzed using one-way ANOVA and Tukey's post-hoc test. Results: The highest mean shear bond strength was found in the 90 se-conds acid application group, which was significantly higher than the control and 30 seconds acid application groups (P<0.05). However, the 60- and 120 se-conds acid application groups showed similar shear bond strength values with the control, 30- and 90 seconds acid application groups (P>0.05). Conclusions: The use of a 60-, 90- and 120 seconds acid application can improve the bond strength between zirconia and resin cement. However, cau-tion should be taken when using this acid due to its potential toxicity and ha-zards.

(Kapadokya Üniversitesi, 2023) Yılmaz Savaş, Tuba; Savaş, Abdulhaluk
Statement of the problem: The challenge of enhancing the bond between zirconia and resin remains, and the efforts continue to determine a simple method for achieving a durable bond. Objective: This study aimed to evaluate the effect of different surface conditioning strategies on the bond strength between zirconia and resin cement. Materials & Methods: Forty zirconia specimens (Lava Plus) were fabri-cated and divided into four groups: control (no surface treatment), primer app-lication (Z-Prime Plus), experimental acid (H2O:HF:H2O2) application, and the combination of the acid and primer application (n=10). A dual-cure resin ce-ment (RelyX Ultimate) was applied over the zirconia specimens. Shear bond strength tests were conducted using a universal testing machine with a cross-head speed of 1 mm/min. The results were analyzed using one-way ANOVA followed by Tukey's post hoc test within the 95% confidence interval. Results: The results of the one-way ANOVA showed that acid applica-tion alone (22.99 ± 2.49 MPa) and acid and primer application (25.24 ± 3.19 MPa) had significantly higher bond strength than the primer (18.87 ± 3.13 MPa) and control (14.91 ± 3.72 MPa) groups (P<0.05). However, there was no significant difference between the acid group and acid and primer combination group (P=0.396). The control group had the lowest bond strength in all test groups (P<0.05).

(Kapadokya Üniversitesi, 2022) Akkese, İpek Balevi; Yılmaz Savaş, Tuba; Pişkin, Bülent
Statement of the problem: The color stability of newly introduced leucite- reinforced feldspathic CAD-CAM ceramic with different surface treatments remains unclear. Objective: This in-vitro study aimed to examine the effect of different surface finishing procedures on the color stability of leucite-reinforced feldspathic CAD-CAM ceramic. Materials & Methods: Twenty-four monochromatic, leucite-reinforced, A2-shaded feldspathic ceramic specimens prepared in 1 mm thickness. The specimens were randomly divided into 3 groups according to their surface finishing methods (n=8): a control group without surface finishing (Group C), surface finishing with polishing discs (Sof-Lex, 3M ESPE), and surface finishing with glaze (Group G). All the specimens were immersed in a coffee solution and kept in an incubator at 37 °C for 14 days. Initial color measurements were made with a digital spectrophotometer and the Commission Internationale de l'Eclairage (CIE) L*a*b* values were recorded. The color measurements were repeated at the ends of the 1st, 3rd, 7th, and 14th days with the spectrophotometer under the same conditions. The color change of the specimens was calculated with the CIEDE2000 (?E00) formula. Statistical analysis of the data was performed with a two-way mixed ANOVA and Bonferroni post-hoc tests (?=0.05).
Facial Blanching As An Unusual Complication After The Injection of Local Anesthesia: A Clinical Report
(Kapadokya Üniversitesi, 2022) Erdoğan, Hilal
Facial blanching is a complication related to local anesthesia in dentistry. Anatomical variation, intravascular injection, rapid local anesthetic injection, decreased blood flow with the vasopressor effect of epinephrine, ortho-retrograde movement of the solution, incorrect positioning of the needle, and neurological origin may cause this phenomenon, the etiology of which is not fully known. Most of the blanching cases reported in the literature are related to injection of the inferior alveolar nerve block. Also, intra-extraoral clinical photography is limited. Supraperiosteal infiltration anesthesia is a safe and easy technique that is frequently used in daily practice in dental clinics. This unique case report describes partial blanching of the face and gingiva after supraperiosteal infiltration of vasoconstrictor containing local anesthetic into the maxilla. In addition, the clinical-anatomical relationship of facial-mucosal blanching with the injection site, literature information, and clinical management with this complication are explained.
