Comparative Evaluation of Simultaneous Maxillary Sinus Floor Elevation and Implant Placement with Residual Bone Heights Greater or Less than 5 mm
(2015) Soydan, Sidika Sinem; Cubuk, Secil; Bayrak, Burcu; Uckan, Sina; 25265126
Purpose: Implants can be inserted simultaneously during sinus floor elevation (SFE), or 6 months later, for posterior maxillary rehabilitation. The residual bone height (RBH) is a major factor that affects the type of surgical procedure that will be performed. The aim of this study was to compare the survival rates of implants inserted during one-stage SFE with two different RBHs (< 5 mm and >= 5 mm). Materials and Methods: This study consisted of implants inserted into an RBH of either < 5 mm or >= 5 mm, and the survival of the implants was assessed according to the clinical symptoms of the patients: pain or tenderness during function (or spontaneously), mobility, depth of probing, exudation history, and radiographic bone loss at the final follow-up appointment. The survival rates of the two groups were statistically compared using the Fisher exact test. Results: Fifty-nine consecutive patients (29 women and 30 men) undergoing a onestage sinus elevation procedure simultaneously with implant insertion were included in this study. Fifty-one implants were placed in the study group (RBH: 1 to 4.9 mm), and 31 implants were placed in the control group (RBH: 5 to 8 mm). The survival rate of the implants in the study group was 94.2% at the 5.4-year follow-up and 95.8% in the control group at the 7.9-year follow-up. There was no statistically significant difference between the groups in terms of the implant survival rate (P = .785). Conclusion: The results of this study suggest that SFE with simultaneous implant placement in patients with an RBH < 5 mm can be accomplished, and that the survival rate is similar to that of the one-stage SFE protocol with an RBH of > 5 mm.
Incidence of root canal treatment of second molars following adjacent impacted third molar extraction
(2016) Oguz, Yener; Soydan, Sidika Sinem; Onay, Emel Olga; Cubuk, Secil; 30894952
Background/purpose: The aim of this study was to evaluate the incidence of requirement for root canal treatment of adjacent second molars following the surgical extraction of an impacted third molar. Materials and methods: The dental records of 6323 consecutive patients who had impacted third molars removed surgically were evaluated and the incidence of postoperative root canal treatment requirement of adjacent second molars was determined. Patients who required root canal treatment of neighboring second molars were accepted as the study group, while the remaining patients were accepted as a control group. Sex, age at the time of the operation, localization of third molar, the depth of impaction, angulation of the tooth, and the professional experience of the surgeon performing the operation were evaluated from patient records. Results: The incidence of requirement of root canal treatment for second molars following a neighboring impacted third molar extraction was 0.17% (11/6323) and invariably occurred in the mandible. The mean age of the study group was found to be significantly higher than the control group (31 years vs. 23 years). The years of professional experience of the surgeons was significantly lower in the study group than in the control group. Conclusion: Although the incidence is minimal, iatrogenic subluxation injuries occurring during the surgical removal of impacted third molars can lead to pulpal complications and a requirement for root canal treatment of adjacent second molars.

Is The Incidence of Temporomandibular Disorder Increased in Polycystic Ovary Syndrome?
(2014) Soydan, Sidika Sinem; Deniz, Kagan; Uckan, Sina; Unal, Asli Dogruk; Tutuncu, Neslihan Bascil; https://orcid.org/0000-0002-3798-7326; https://orcid.org/0000-0002-1816-3903; 25124832; ABG-5027-2020
The prevalence of temporomandibular disorders is higher among women than men (ratio 3:1 -9:1). Polycystic ovary syndrome(PCOS) is the most common endocrine disorder in women, which is characterised by chronic low-grade inflammation and excess of androgenic hormones that lead to metabolic aberrations and ovarian dysfunction. Increased activities of various matrix metalloproteinases (particularly MMP-2 and 9) in the serum of these patients has been reported, and it has been hypothesised that high activities of MMP may contribute to loss of matrix and chronic inflammation of the fibrocartilage in temporomandibular disorders. Our aim was to evaluate the incidence of temopormandibular dysfunction in women with PCOS compared with an age-matched, disease-free, control group. We studied 50 patients with previously diagnosed PCOS and 50 volunteers who had normal menstrual cycles. We made a comprehensive clinical examination of the temporomandibular joint (TMJ) and muscles of mastication in both groups and recorded the Visual Analogue Scores (VAS) for pain. There were significant differences (p<0.001) in the incidence of temporomandibular disorders (n=43 (86%) in the PCOS group compared with n=12 24% in the control group), muscle tenderness(n=32 (64%) in the PCOS group compared with n=14 (28%) in the control group) and pain in the TMJ (mean (SD) VAS 2.9 (2.61) compared with 0.3 (1.56). We confirm the higher incidence and severity of disorders of the TMJ in patients with PCOS and suspect that chronic low-grade inflammation may play a part in the aetiology of the disease.

Management of Bisphosphonate-Related Osteonecrosis of the Jaw With a Platelet-Rich Fibrin Membrane: Technical Report
(2014) Soydan, Sidika Sinem; Uckan, Sina; 24075235
Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a challenging complication resulting from the long-term application of bisphosphonates. In most cases, BRONJ occurs after a surgical procedure involving the jawbone. Currently, the management of BRONJ remains controversial, and there is no definitive treatment other than palliative methods. Platelet-rich fibrin (PRF) represents a relatively new biotechnology for the stimulation and acceleration of tissue healing and bone regeneration. This technical note describes the total closure of moderate bone exposure in persistent BRONJ in 2 weeks with a double-layer PRF membrane. PRF may stimulate gingival healing and act as a barrier membrane between the alveolar bone and the oral cavity. PRF may offer a fast, easy, and effective alternative method for the closure of bone exposure in BRONJ. (C) 2014 American Association of Oral and Maxillofacial Surgeons
Psychosocial and Functional Outcomes of Orthognathic Surgery: Comparison with Untreated Controls
(2015) Sar, Cagla; Soydan, Sidika Sinem; Ozcirpici, Ayca Arman; Uckan, Sina; 0000-0002-9250-3689
Objectives: Orthognathic surgery is a procedure for patients with dentofacial deformities and provides dramatical dentofacial and psychological alterations. The aim of this controlled study was to evaluate how orthognathic surgery affects patients' psychosocial well-being and compare them with patients having dentofacial discrepancies and with individuals who do not have any skeletal discrepancies. Methods: Hundred and sixty-three adult individuals were included in this study as three groups: patients who underwent orthognathic surgery, patients having skeletal discrepancies and individuals who do not have any skeletal discrepancies. Patients in all groups were asked to fill out two questionnaires concerning the psychological and physical status of the patients at that moment and additional questions were asked to patients in post-surgical phase regarding post-surgical satisfaction. Categorical variables were statistically evaluated by Fisher Exact and chi-square tests. Results: Patients who were going to seek orthognathic surgery were significantly concerned about their dentofacial appearance, body image and psychosocial status when compared with patients in the post-surgical phase and the individuals who did not have skeletal discrepancies. The results of the patients who underwent orthognathic surgery were approximated to the results of non-patient control group and had high degrees of satisfaction with improvement in appearance brought about by surgery at 6-month post-operatively. Conclusion: Following orthognathic surgery, patients had better psychosocial status when compared to patients without skeletal deformities. Patients in the pre-surgical phase were not only functionally but also psychosocially the least satisfied group of individuals. (C) 2014 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.
