Abstract
BACKGROUND Laser application for the treatment of peri‑implantitis provides a variety of advantages; however, depending on the laser type and parameters, it may also have adverse effects on the implant surface qualities. This study's objective is to assess the effects of laser type and parameters on the surface properties of two different titanium-based implant materials: titanium Grade 4 (Ti-Grade 4) and titanium zirconium (Ti-Zr) discs with sand-blasted and acid-etched (SLA) surfaces under in vitro conditions. MATERIAL & METHOD Sand-blasted and acid-etched discs made of titanium grade 4 (Ti-Grade 4) and titanium zirconium (Ti-Zr) were treated using 808 nm AlGaAs (diode) and 2940 nm Er:YAG lasers with varying parameters (i.e., diode laser in continuous wave mode, Er:YAG in short pulse mode, and Er:YAG in variable square pulse mode with four different doses). Then, the surface morphology and topography of the treated discs were characterized using scanning electron microscopy and optical profilometry. RESULTS The 3D surface topographies of discs treated with a high power Er:YAG laser displayed irregular peaks and deep valleys, indicating surface deterioration. The average surface roughness values (Sa) of both discs varied with laser type and parameters (3.55-4.80 µm for Ti-Grade 4 versus 3.25-4.5 µm for Ti-Zr). With diode laser applications, the topography features of the discs were preserved despite a small number of irregular valleys and peaks. However, the surface morphologies of the discs were dramatically altered by erosion and local melting because of the Er:YAG laser treatment. CONCLUSION Diode laser application appears to be the most reliable method for treating peri‑implantitis, as diode laser-treated implants retained their overall surface quality despite a small number of irregular peaks and valleys.

Abstract
OBJECTIVE The purpose of this study is to assess the impact of Sagittal Split Ramus Osteotomy (SSRO) on the alignment of the condyle and orientation of the Ramal segment following surgery in patients operated for the correction of mandibular asymmetry. METHODS A total of 27 patients who underwent SSRO were enrolled in this study, and study groups were defined as asymmetric (study group) and symmetric (control group) using linear measurements from the dental midline based on a three-dimensional coordinate system. Differences on preoperative and postoperative values of anterior (AJS), posterior (PJS) and superior joint spaces (SJS), condylar axial angle (CAA), Sagittal Ramal Angle (SRA), and Coronal Ramal Angles (CRA) of study and control groups were measured and compared. The data was analyzed using the "Wilcoxon signed-ranks test" to identify differences between groups. RESULTS Differences between preoperative and postoperative values of CRA and SRA of the contralateral group showed statistically significant results with p-values of 0.007 and 0.005, respectively. A statistically significant change in CAA angle was found in the control and deviation groups (p = 0.018 and p = 0.010, respectively). CONCLUSIONS SSRO has inevitable effects on the condylar and ramal orientation. Individuals with asymmetry require particular attention throughout the planning process and beyond. Conjunctive modalities and modifications should be considered and utilized when necessary. Future studies with larger sample sizes, homogenous follow-up periods, and more comprehensive clinical data are needed to substantiate understanding of the response of the condylar segment. CLINICAL RELEVANCE Orthognathic surgeries inevitably alter the alignment and harmony of temporomandibular structures and may result in change of AJS, PJS, SJS, CAA, SRA, and LRA, which may change the biomechanics of joint and lead to several complications like temporomandibular disorders. Especially in cases with midline asymmetry needs special consideration from planning till the end of the treatment to achieve best results. In severe cases, conjunctive modalities and modifications and other alternatives such as inverted-L osteotomies should be considered.

Abstract
PURPOSE To evaluate oral health-related quality of life (OHRQoL) and satisfaction levels related to treatment in patients who have complete implant treatment and prosthetic rehabilitation after anterior iliac crest grafting. MATERIALS AND METHODS Fifty-four patients (37 F, 17 M) with a total of 487 implants placed and implant-supported fixed prosthesis treatment completed were included in the study. OHIP-14OHIP-14 scale and satisfaction Likert scale questions were used to evaluate the OHRQoL and the satisfaction levels related to the treatment applied, respectively. To compare the outcomes, the significance test and the Mann-Whitney U-test were used. One-way analyses of variance and Kruskal-Wallis were used to assess the significance of differences among or between the groups. RESULTS The quality of life (QoL) was higher, and the mean OHIP-14 scores were lower in women, older patients, and cases with a longer follow-up period, recorded as 13.6 ± 10.3 (p: 0.263), 12.9 ± 11.3 (p: 0.079), and 11.8 ± 9.6 (p: 0.015*), respectively. Moreover, satisfaction levels of the patients related to the treatment were 83.3%. CONCLUSIONS The treatment of severely atrophic jaws with anterior iliac crest for the implant and prosthetic rehabilitation has a positive effect on the QoL. This effect has increased with time, and the satisfaction levels of the patients related to this procedure were high, and their expectations regarding this treatment were met at a high level.

Abstract
Background A 6‐week Phase I clinical trial was performed to primarily evaluate the safety and secondarily determine the preliminary efficacy of a novel biological solution, ST266, comprised of a mixture of cytokines, growth factors, nucleic acids, and lipids secreted by cultured amnion‐derived multipotent progenitor cells on gingival inflammation. Methods Fifty‐four adults with gingivitis/periodontitis were randomly assigned to 1X ST266 or diluted 0.3X ST266 or saline topically applied on facial/lingual gingiva (20 µL/tooth). Safety was assessed through oral soft/hard tissue exam, adverse events, and routine laboratory tests. Efficacy was assessed by modified gingival index (MGI), bleeding on probing, plaque index, probing depth (PD), and clinical attachment level (CAL). Assessments were performed on day 0, 8, 12, and 42. ST266 and saline applied daily starting at day 0 through day 12 except weekend days. Plasma was analyzed for safety and proinflammatory cytokines, interleukin (IL)‐1β, IL‐6, tumor necrosis factor‐alpha, and interferon gamma. Gingival crevicular fluid (GCF) was analyzed for the same cytokines. Subgingival plaque was primarily analyzed by checkerboard DNA‐DNA hybridization. Comparisons with saline were modeled through a generalized estimating equations method adjusting for baseline. Results No safety concern was found related to ST266. Statistically significant reduction in MGI was noted at day 42 by 1X ST266 compared with saline (P = 0.044). PD and CAL were reduced by both doses of ST266 at day 42 (P <0.01) and by 1X ST266 at day 12 (P <0.05). GCF IL‐1β and IL‐6 levels were reduced by both doses of ST266 at day 12 (P <0.05, P <0.01, respectively). IL‐6 was also significantly reduced in plasma of both ST266 groups (P <0.05). Significant reductions in red complex bacteria were detected in both ST266 doses. Conclusions In this “first in human oral cavity” study, topical ST266 was safe and effective in reducing gingival inflammation in 6 weeks. Longitudinal studies with large sample sizes are warranted to assess the therapeutic value of this novel host modulatory compound in the treatment of periodontal diseases.

Abstract
PURPOSE This study was designed to evaluate the effects of four different surgical techniques on the primary stability of short implants in two sizes (4-mm and 6-mm length) through resonance frequency analysis and insertion torque measurement in vitro. MATERIALS AND METHODS Forty implant site preparations and implant insertions were performed in pig ribs. Guided surgery, bone condensing, conventional drilling, and undersized preparation surgical techniques were used five times in each bone block to prepare 4-mm/6-mm-length implant beds. The maximum insertion torque and implant stability quotient (ISQ) values were recorded for each implant. RESULTS Both the ISQ and torque differed significantly for various surgical techniques (P = .009 and P < .001). The conventional technique had higher ISQ (79.00), whereas the condenser technique had higher torque (48.00 Ncm) than did the other techniques. The mean torque was significantly higher in all surgical techniques other than the guided surgery group regardless of implant length (P < .01 for all). Implant lengths were not significantly different in terms of ISQ and torque in all surgical techniques. CONCLUSION There are significant correlations between the implant bed preparation technique and primary implant stability when using short implants. Conventional surgery and the bone condensing technique are favorable alternatives with higher primary stability and torque values in short implants.

Abstract
We aimed to assess element status in whole blood and tooth dentin and identify their correlations in overweight or obese children without additional metabolic risk factors. In a case-control study, 40 overweight and 80 normal weight children aged 6-10 years were enrolled. Samples of blood and tooth were collected. While all studied elements were similar in groups in univariate analysis, after adjustment for confounding factors, tooth Mn levels were lower and blood Zn levels were higher in the overweight/obese group (p = 0.049 and p = 0.032, respectively). A significant correlation in blood and tooth dentin levels of Sr and Zn was detected in both groups. In both biological substances, the concentrations of elements did not differ significantly in overweight children without metabolic comorbidities compared to healthy children of normal weight. Presence of low Mn levels in tooth dentin and high Zn levels in blood samples should be explored in further studies.

Abstract
Background Odontogenic keratocysts have been reported with high recurrence rates in the literature so various treatment modalities from simple enucleation to resection have been performed to achieve the cure. The purpose of this retrospective study was to investigate the recurrence rate of odontogenic keratocysts (OKCs) treated by enucleation and peripheral ostectomy. Material and Methods An electronic search of the database of the Hacettepe University, Faculty of Medicine, Department of Pathology, was undertaken to identify patients histologically diagnosed with OKCs treated at Department of Oral and Maxillofacial Surgery between 2001 and 2015. Results In total, 81 patients were studied. The mean age at the time of diagnosis was 42 years, and the male:female ratio was 1:0.7. OKCs were located primarily in the posterior mandibular region (41%). Twenty-seven patients were re-examined to determine the recurrence rate. The mean follow-up period was 5 years (range, 1–12 years). The recurrence rate was 14.8%. The relationship between location of the lesion and recurrence was not statistically significant (p = 0.559). There was also no statistically significant relation between the recurrence rate and treatment option of teeth involved in the lesion (p = 0.579). Conclusions The authors conclude that treatment of OKCs by enucleation with peripheral ostectomy is associated with minimal morbidity and is preferred over other aggressive treatment modalities. Meticulous radiographic examination and careful surgical resection may decrease the recurrence rate of OKCs. Key words:Odontogenic keratocyst, recurrence rate, enucleation, enucleation plus peripheral ostectomy.

Abstract
OBJECTIVE The aim of this study was to compare the peri-implant bone level changes of implants placed during and 3 months after bone grafting from the iliac crest. STUDY DESIGN A total of 103 implants were placed: 42 during the grafting and 61 at 3 months after the grafting procedure. All patients were grafted with iliac bone from the anterosuperior iliac crest. Bone resorption was evaluated with cone beam computed tomography in all patients at their last control visit. Periodontal health was assessed via the gingival and plaque indices and pocket depths around the dental implants. RESULTS Mean bone resorption values at the buccal, lingual, mesial, and distal sides of the implants were 1.08 mm, 0.36 mm, 0.30 mm, and 0.25 mm, respectively, in the delayed group, and 1.87 mm, 1.25 mm, 0.92 mm, and 1.23 mm, respectively, in the simultaneous group; the differences between the groups were significant. There were no significant between-group differences in the gingival or plaque indices or pocket depths. The mean follow-up period was 29 months. CONCLUSIONS For reconstructing atrophic jaws, bone grafting from the iliac crest and implant placement after 3 months is a reliable technique with a high success rate and less bone resorption.

Abstract
The objective of the present study was to test the hypothesis that the addition of hyaluronic acid-based matrix to collagenated heterologous bone graft for sinus augmentation would enhance bone formation compared to collagenated heterologous bone graft alone in the early healing period, by micro-computed tomography and histomorphometry. Thirteen systemically healthy patients requiring bilateral two-stage maxillary sinus augmentation (residual crest height≤4mm) were enrolled in this split-mouth prospective randomized controlled study. One sinus side as a control group was grafted with only collagenated heterologous bone graft; the other region as a test group was grafted with hyaluronic matrix and collagenated heterologous bone graft. Bone biopsy samples were taken after 4 months during the dental implant surgery and analyzed using micro-computed tomography and histomorphometric parameters. According to the micro-computed tomography and histomorphometric results, a significantly higher percentage of new bone was observed in the test group when compared to the control group after 4 months of healing. This study confirmed the hypothesis that the addition of hyaluronic matrix to collagenated heterologous bone graft for sinus augmentation enhances bone formation compared to collagenated heterologous bone graft alone in the early healing period.

Abstract
The presented case evaluates the treatment of an alveolar fracture associated with mandibular immature lower permanent incisors. An 8-year-old girl was referred to our clinic 3 hours after the trauma. The clinical and radiographic examination of the alveoler bone showed a fracture, along with the mandibular fracture and significant segment mobility and dislocation of several immature mandibular permanent incisors. These were moving together to the lingual side because of the direct trauma associated with falling from the school wall. After the application of the buccal and lingual infiltration of local anaesthesia, the dislodged bone including the lower permanent incisors, were carefully repositioned. The teeth were splinted using semi-rigid arch bars with orthodontic brackets keeping the teeth between primary molars.The splints were removed one month later and no abnormality was observed in the immature permanent incisors. After 24 months follow up, the mandibular permanent incisors were observed to have the apical closure. Treatment of alveolar fractures in growing children with immature teeth may provide beneficial healing pattern with careful semi-rigid splinting and follow up procedures.

Abstract
OBJECTIVE To investigate the preventive effect of locally applied sodium bicarbonate on bisphosphonate-related osteonecrosis of the jaw (BRONJ). STUDY DESIGN Thirty-six Sprague-Dawley rats were divided into 4 groups. Animals in group I received 0.1 mg/kg sterile saline 3 times per week for 8 weeks. Groups II, III, and IV received intraperitoneal zoledronate injection in the same manner with the same frequency and duration. The right first molar tooth was extracted in groups III and IV. One mL 8.4% sodium bicarbonate (SB) was applied to the extraction socket at the time of extraction in group IV. The effect of locally applied SB as an alkalizing agent was evaluated by histomorphometric analysis. RESULTS BRONJ was observed in none of the animals in the control groups, 67% of the animals in the tooth extraction group, and none of the animals in the local SB application group (P < .01). CONCLUSIONS Administration of locally applied SB had positive effects on the prevention of BRONJ in animals, but further studies are required to verify the effectiveness of this form of treatment before its use in humans.

Abstract
OBJECTIVE To determine the relative success of two different bone grafting material - putty and powder forms of De-mineralised Bone Matrix (DBM) - used in sinus lift procedure. METHODS The retrospective study was conducted at the Department of Oral and Maxillofacial Surgery, Ankara University, Ankara, Turkey, and comprised data related to the patients referred for bilateral maxillary sinus augmentation between 2007 and 2010. During the period, 48 endoosseous implants were placed concurrently with the sinus augmentation in 12 patients. Marginal bone loss around the implants was measured at the time of loading, 12 and 30 months after the treatment. SPSS 11.5 was used for data analysis. RESULTS Of the 12 patients, 8 (66.6%) were females and 4 (33.3%) were males. All implants osseointegrated in both the putty and powder groups well without any significant clinical finding. The average volume of marginal bone resorption at implants for the putty side was 0.43 +/- 0.22 mm, 0.8 +/- 0.33 mm and 1.12 +/- 0.49 mm at prosthetic loading, 12-month and 30-month follow-up, respectively. For the powder side, the corresponding numbers were 0.48 +/- 0.32 mm, 0.82 +/- 0.46 mm and 1.24 +/- 0.57 mm. No statistically significant difference in bone loss between the two groups was observed (p > 0.05). CONCLUSION Both putty and powder forms of de-mineralised Bone Matrix showed satisfactory results and there was no significant difference in marginal bone loss around dental implants and survival rates.

Abstract
OBJECTIVE Increased experience in sinus lifting procedures has led to a number of literature reports, but the potential effects of sinus lifting on voice quality is not clearly addressed in clinical studies. The aim of this study was to objectively investigate the effects of sinus lifting on alterations in voice quality and, in particular, on vocal resonance. STUDY DESIGN A total of 17 patients who were in need of bilateral sinus augmentation were recruited. Acoustic analyses were performed before and after surgery. Volume changes in the sinuses were recorded before and after surgery using dental volumetric tomography. The Friedman test with Bonferroni correction was used to analyze the data. RESULTS Changes in the perturbation parameters of acoustic sound analysis were found to be statistically significant. CONCLUSIONS We recommend that all patients (especially voice professionals) be informed about the possible effects of sinus lifts on speech and voice alterations.

Abstract
This study evaluated the Amor and European Spondylarthropathy Study Group (ESSG) classification criteria for spondyloarthropathies in Turkish patients seen from October 1990 to August 1993 at the Physical Medicine and Rehabilitation Department of the GATA Haydarpasa Training Hospital. The Amor and ESSG criteria were evaluated in 157 patients with spondylarthropathies and in 124 controls with a variety of other rheumatic diseases. The sensitivity, specificity, positive predictive value, and negative predictive value of each criteria set were calculated, as well as the sensitivity and specificity of each of the 24 criteria used in these sets. For Amor's criteria, sensitivity was 88.5%, specificity was 91.9%, positive predictive value was 93.3% and negative predictive value was 86.4%. For the ESSG criteria, sensitivity was 86.6%, specificity was 91.1%, positive predictive value was 92.5% and negative predictive value was 84.3%. No significant differences were found between the two criteria sets. Our data show that the Amor and ESSG criteria are of similar value for the classification of spondylarthropathies and are comparable in terms of sensitivity and specificity. They also demonstrate the need for monitoring patients with equivocal clinical patterns using both sets of criteria as tools that complement each other.
