The Comparison of Dental Anxiety between Patients Treated with Impacted Third Molar Surgery and Conventional Dental Extraction.

BACKGROUND: The aim of the present study is to compare the dental anxiety levels between two outpatient clinics. METHODS: Two hundred and seventy patients treated in two different clinics of minor oral surgery and dental extraction polyclinic in the Dental Faculty of Eskisehir Osmangazi University were included in the study. The impacted third molar surgery group and conventional dental extraction group consisted of 101 and 169 patients, respectively. The Modified Dental Anxiety Scale (MDAS) and Dental Fear Scale (DFS) were used to measure anxiety levels in patients treated in both clinics. Tests were made in an isolated room preoperatively. The differences in anxiety levels according to education status and gender were also evaluated. RESULTS: The impacted third molar surgery group showed a significant increase in dental anxiety measured with DFS questionnaire (p < 0.05). However, MDAS revealed that there was no difference between anxiety levels between the impacted third molar surgery and conventional dental extraction groups (p > 0.05). There was also no difference in anxiety levels between patients with different education status (p > 0.05). Female patients demonstrated higher levels of anxiety in both MDAS and DFS indexes (p < 0.05). CONCLUSION: Dental anxiety may be higher in patients treated with impacted third molar surgery compared with conventional dental extraction. The education status of patients may not affect dental anxiety. Female patients may show increased levels of dental anxiety in conventional dental and impacted third molar extractions.

Two-Dimensional Change in the Cystic Defects after Decompression and Enucleation of Jaw Cysts - A Comparative Study.

Introduction: To compare the treatment methods of enucleation and decompression with regards to reduction of the dimension of the cystic defect with the aid of a software program. Materials and Methods: Thirty patients with regular controls of 3, 6, and 12 months treated between January 1, 2013, and January 1, 2021, were selected and included in the study. Sixteen patients were treated with enucleation and 14 patients with decompression. All preoperative and control radiographic and clinical data were retrieved from the archives. The area measurement of cystic cavities was made on panoramic radiographs taken at preoperative (T0), 3-month (T1), 6-month (T2), and 12-month (T3) control periods with a software program. Intra-group and inter-group analyses were made to compare the reduction of cystic defects between two treatment methods. Results: The mean age of study patients was 45.2 ± 7.3. Eighteen of them were male and 12 of them were female. Statistically, a significant difference was not observed between decompression and enucleation groups at T0, T1, T2, and T3 control periods (P > 0.05). There was a statistically significant difference in the defect dimensions between all control periods in both decompression and enucleation groups (P < 0.05). Discussion: Decompression and enucleation of jaw cysts are both successful in reducing cystic cavities. However, there is no superiority between the two treatment modalities regarding the defect reduction at the 12-month control period.

The influence of flap design on sequelae and quality of life following surgical removal of impacted mandibular third molars: A split-mouth randomised clinical trial.

BACKGROUND: Surgical removal of impacted mandibular third molar is one of the most frequently performed interventions in oral and maxillofacial surgery. OBJECTIVES: To compare two different flap designs in terms of sequelae and quality of life following surgical removal of impacted third molars. METHODS: This prospective, randomised, split-mouth clinical study involved patients referred for surgical removal of bilateral symmetrical impacted mandibular third molars. Envelope flap and modified triangular flap techniques were used. The effects of flap design on trismus, swelling, wound dehiscence, alveolar osteitis, haematoma, infection and quality of life were evaluated on post-operative days 3 and 7. Pain levels were assessed on post-operative days 1, 3 and 7. RESULTS: Significant differences were determined between the two groups in terms of trismus, pain and wound dehiscence scores on post-operative day 3. However, on post-operative day 7, this difference was observed only in trismus. Statistically significant differences were also determined between the two groups on post-operative day 3 for social isolation and eating subscale scores as well as total quality of life score. CONCLUSION: Based on the study findings, the modified triangular flap may be superior to the envelope flap in terms of pain, trismus, and wound dehiscence in the first 3 days after impacted third molar surgery and may have a better impact on quality of life during this process.

A decision analysis for periapical surgery: Retrospective Study.

BACKGROUND: Periapical surgery is now a reliable therapeutic procedure for the treatment of teeth with periapical lesions, particularly when orthograde retreatment is problematic. However, little information is available regarding treatment planning of cases referred for periapical surgery. Therefore, this study was conducted to analyze and evaluate the factors that affect the decision-making process for periapical surgery. MATERIAL AND METHODS: This study retrospectively assessed clinical and radiographic data from patients undergoing periapical surgery. The factors involved in deciding to perform periapical surgery were classified into technical, biological, and combined factors. RESULTS: Out of 821 patients, 544 (66.3%) underwent endodontic treatment/retreatment, 204 (24.8%) were treated with coronal restorations and 60 (7.3%) were treated with post. Periapical surgery was indicated for biological reasons in 35% of patients and for technical reasons in 17.9%. The common biological factor was persistent clinical symptoms (19.7%). The most common technical cause was failure of previous endodontic treatment (66.3%). Nearly half of all periapical lesions (45%) were <5 mm in size. Periapical surgery was justified in only 434 (52.9%) subjects. CONCLUSIONS: We suggest that it is very important for patients to be informed and encouraged about endodontic retreatment in order to reduce unnecessary surgical procedures. Key words:Periapical surgery, case selection, treatment planning.

Evaluation of Blood Titanium Levels and Total Bone Contact Area of Dental Implants.

The purpose of this study was to evaluate the effect of total implant-bone surface contact area of dental implants applied on partial or total edentulous patients on the increase in the level of blood titanium level. Changes of the blood titanium levels were evaluated after placement of the dental implants in 30 patients including 15 females and 15 males. Patients were divided into 3 groups as dental implants were applied on only maxilla, only mandible, or both of them. Taking into the consideration anatomic formation and prosthetic indication, dental implant-bone total contact area was calculated and saved for each patient after dental implants placement. Blood samples of the patients taken preoperatively and postoperatively at 12 weeks were analyzed by ICP-MS device. Blood titanium levels of preoperative and postoperative blood samples were analyzed for each patient and results were evaluated statistically. In the evaluation after analyzing blood titanium level changes, while a statistically significant decrease was observed in Group 1 patients, a statistically significant increase was observed in Group 2 and Group 3 patients to blood titanium level. A statistically significant difference was observed between Group 1 and Group 2 and between Group 1 and Group 3 patients of blood titanium levels. The change of the blood titanium level was not related to total implant-bone surface area, number of the implants, and gender. In our study, no correlation was found between change of blood titanium level and total contact area with bone of dental implants. We believe that more accurate results can be obtained with biopsy of tissues and organs on animal studies.

Evaluation of oxidative status in patients with chronic periodontitis and polycystic ovary syndrome: A cross-sectional study.

BACKGROUND: In patients with polycystic ovary syndrome (PCOS), chronic periodontitis (CP) contributed to increased oxidative stress (OS), owing to an increase in serum and salivary 8-hydroxy-2'-deoxyguanosine (8-OHdG) and malondialdehyde (MDA) levels and a decrease in serum total antioxidant status (TAS) levels. The aim of the present study is to investigate salivary and serum 8-OHdG and MDA levels as well as total antioxidant status (TAS) in females with CP and PCOS compared with healthy females. METHODS: Four groups, each consisting of 22 individuals, were: 1) women with both PCOS and CP (PCOSCP); 2) systemically healthy women with CP; 3) periodontally healthy women with PCOS (PCOSPH); and 4) periodontally and systemically healthy women (PH). Demographic and clinical periodontal parameters were measured. Oxidative parameters were evaluated in serum and salivary samples. RESULTS: Salivary 8-OHdG levels in the PCOSCP and CP groups were statistically higher than those in both the PCOSPH and the PH groups (P < 0.05). There was no statistical difference between the PCOSCP, CP, and PCOSPH groups with regard to salivary MDA and TAS levels (P > 0.05). Highest serum 8-OHdG and MDA levels and lowest serum TAS levels were seen in the PCOSCP group (P < 0.05). Serum 8-OHdG and MDA levels in the PCOSPH group were higher than those in both systemically healthy groups (PH and CP) (P < 0.05). Salivary TAS levels were highest (P < 0.05) in the PH group. There was no statistical difference between the CP and PCOSPH groups, but serum TAS levels were lower than those in the PH group (P < 0.05). CONCLUSIONS: CP, which led to an increase in serum and salivary 8-OHdG and MDA levels and a decrease in serum TAS levels in patients with PCOS, contributed to increased OS. This effect was more prominent in serum levels than in salivary levels.

Determining the Margin of Safety for Damaging the Sphenoid Sinus with Nasal Septum Osteotome during Le Fort I Surgery in Young Adults.

Nasal septum (Obwegeser) osteotome is a basic instrument used for separating the nasal septum and maxilla during Le Fort I osteotomy. If this instrument is placed too high or tilted into the nasal cavity, sphenoid sinus and various adjacent vital structures may be damaged and serious bleeding, neurological complications, or blindness or even death may occur. The aim of this study is to determine the margin of safety for damaging the sphenoid sinus and the adjacent structures with nasal septum osteotome in the young adults: 49 male and 51 female patients between 15 and 25 ages who required a Cone Beam Computed Tomography (CBCT) examination as part of their routine examination. In the study sample consisting of CBCT images, the aimed surgical line, the line between spina nasalis anterior and vomer and the base of sphenoid sinus (undesired line), and tilt angle between surgical and undesirable lines were measured. As the primary outcome of this study, margin of safety for damaging the sphenoid sinus and adjacent vital structures with nasal septum osteotome during Le Fort surgeries in young adults recommended as 5 mm and 120. For this reason the importance of planning with preoperative CBCT before Le Fort I osteotomies has been revealed.

Evaluating of Platelet-Rich Fibrin in the Treatment of Alveolar Cleft With Iliac Bone Graft By Means of Volumetric Analysis.

The purpose of this study was to evaluate the efficiency of platelet-rich fibrin usage in the treatment of alveolar cleft with iliac bone graft by means of volumetric analysis. In this study, 22 patients with alveolar clefts-including 13 unilateral and 9 bilateral-were treated with anterior iliac crest bone grafts. Patients were divided into 2 groups as control (group A) and platelet-rich fibrin (group B) groups. Cone beam computed tomography (CBCT) scans were obtained preoperatively and 6 months postoperatively. Three-dimensional reconstructions of CBCT images were created by using Mimics software. Preoperative alveolar cleft volume and postoperative newly formed bone volume were assessed volumetrically. The percentages of preoperative alveolar cleft volume ranged from 0.51 to 2.04 cm, with a mean volume of 0.98 ±â€Š0.33 cm. The percentages of newly formed bone in group B ranged from 50.70% to 80.09%, with a mean percentage of 68.21 ±â€Š10.80%. In Group A, the percentages of bone formation ranged from 47.02% to 79.23%, with a mean percentage of 64.62 ±â€Š9.49%. Platelet-rich fibrin can be used in the treatment of alveolar cleft with corticocancellous bone graft harvested from the anterior iliac crest, but in this study, there was no statistically significant difference between the groups for postoperative newly formed bone volume (P > 0.05).

An Analysis of Mandibular Symphyseal Graft Sufficiency for Alveolar Cleft Bone Grafting.

The purpose of this study was to evaluate the sufficiency of the mandibular symphysis as a donor site for unilateral and bilateral alveolar grafting, measuring both the alveolar cleft volume and maximum bone graft volume that can be harvested from the mandibular symphysis using 3-dimensional computed tomography (CT) and software in children and adults. Computed tomography data obtained from 20 unilateral and bilateral cleft lip palates patients in the preoperative period were used in this study. The patients were divided into 2 groups: children (female, n = 5; male, n = 5) and adults (female, n = 5; male, n = 5). The required bone graft volume for grafting and the maximum bone graft volume that can be harvested from the mandibular symphysis were measured based on cone beam CT data and software. The average required bone graft volume (cleft volume) for unilateral alveolar grafting was 963.51 ±â€Š172.31 mm in the children and 1001.21 ±â€Š268.16 mm in the adults. The average required bone graft volume for bilateral alveolar grafting was 1457.82 ±â€Š148.18 mm in the children and 2189.59 ±â€Š600.97 mm in the adults. The average the mandibular symphysis bone graft volume was 819.29 ±â€Š330.85 mm in the children and 2164.9 ±â€Š1095.86 mm in the adults. The results demonstrated that the mandibular symphysis region provided an adequate bone volume for alveolar grafting in adults with unilateral alveolar clefts. However, it is difficult to standardize these results, due to cleft volume and graft volume that could be harvested from the mandibular symphysis are highly variable among individuals.

Surgical Treatment of Class III Malocclusion: Monozygotic Twin.

Mandibular deformities present with infinite variation with different aesthetic and functional problems. Orthognathic surgery is required to achieve satisfactory results for functional and aesthetically in mandibular prognathism patient. Setback of the mandible to correct mandibular prognathism is a well-known procedure. The 2 most frequently used techniques are the intraoral vertical ramus osteotomy and the bilateral sagittal split ramus osteotomy (BSSRO). Bilateral sagittal split ramus osteotomy is an effective and commonly used method to correct mandibular prognathism. In this patient report, mandibular prognathism in female monozygotic twin patients was treated with BSSRO is presented.
