(Springer Japan Kk, 2020) Çakır, Merve; Yalçın Ülker, Gül Merve; Meral, Deniz Gökçe; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial Surgery
Purpose Although various prophylactic and/or postoperative systemic antibiotic regimens have been suggested to minimize failure after dental implant placement and postoperative infection, the role of antibiotics in implant dentistry is still controversial. The purposes of this questionnaire study were to determine the current antibiotic prescribing habits of clinicians in conjunction with dental implant placement and to understand whether any consensus has been reached among implant surgery performing clinicians. Methods An electronic questionnaire was sent by electronic mail to all members of the Turkish Dental Society. The questions were related to whether antibiotics were routinely prescribed either pre- or/and postoperatively during routine dental implant placement. The respondents were also asked to specify their workplace and education. The results were analyzed using SPSS software. Descriptive and chi-square analyses were used to compare categorical data; Kruskal-Wallis test was used to compare the quantitative data by category. Results A total of 429 members responded to the questionnaire. The clinicians having more experience had a greater tendency to prescribe preoperative antibiotics (p< 0.001), but there was no statistically significant difference between the postoperative antibiotic prescription choice of the clinician according to the clinicians' experience (p> 0.05). A total of 175 of the clinicians preferred to prescribe preoperative antibiotics when there was systemic comorbidity; 99 of the clinicians preferred to prescribe antibiotics before every implant surgery. The aminopenicillins were the most commonly prescribed antibiotics by the clinicians. A total of 38.58% of the respondents (n= 130) who were prescribing preoperative antibiotics, 2000 mg aminopenicillin was given 1 h before the surgical procedure. Dentists and solo private practitioners were prescribing more preoperative antibiotics (p< 0,05). Conclusions There was no consensus among clinicians regarding the use of antibiotics in association with routine dental implant placement. Aminopenicillins were the most commonly prescribed antibiotics for both pre- and postoperatively. Furthermore, most of the antibiotic regimens being used are not in accordance with the current published data.

(Mary Ann Liebert, inc, 2020) Bozkaya, Suleyman; Çakır, Merve; Peker Tunc, Elif; Ogutlu, Faruk; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial Surgery
Objective:The purpose of this study was to evaluate the effect of photobiomodulation (PBM) therapy on neurosensory recovery of inferior alveolar nerve (IAN) and lingual nerve (LN) injuries. Background:PBM has favorable stimulating and therapeutic effects in the living tissues, and promotes neuron maturation and regeneration in injured nerves. Methods:Fifty patients with the neurosensory deficit of IAN and/or LN, developed as a consequence of dental or oral and maxillofacial surgery procedures enrolled in this study. Paresthesia of the patients was confirmed by subjective and objective neurosensory tests. Subjective evaluation was done by rating the patient's numbness by visual analog scale (VAS) from 0 (normal) to 10 (most severely affected). Objective neurosensory assessment was done by two-point discrimination, thermal stimuli, light touch, and pinprick tests. All patients were treated with PBM (830 nm, 70 mW) three times a week for 10-16 sessions. Subjective and objective evaluations were done before and after treatment. Statistical analysis was performed by single sample Kolmogrov-Smirnov test for normality and the Levene test for homogeneity and the data examined by two-way repeated measures analysis of variance (ANOVA) (alpha = 0.05). Results:This study included 50 patients, between 18 and 67 years of age, with a mean of 38 years (standard deviation = 15.1). The causes of the neurosensory deficiencies were removal of impacted third molar (54%) and other dental procedures (46%). There was a significant decrease on VAS scores in neurosensory deficit (p = 0.0) and the objective test total scores were significantly higher after the treatment (p = 0.0). Conclusions:It might be concluded that PBM treatment can provide subjective and objective improvements in long or/and short-term neurosensory deficits and can be used as a noninvasive treatment method.

Effect of Residual Bone Height and Implant Macro-Design on Primary Stability in Sinus Floor Elevation: An Ex Vivo Study
(Allen Press inc, 2023) Tokuc, Berkay; Çakır, Merve; Kan, Bahadır; Yalçın Ülker, Gül Merve; Meral, Deniz Gökçe; Kan, Bahadir; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial Surgery
The objective was to evaluate the influence of residual bone height (RBH) and implant macro -design on the primary stability (PS) of implants using a simultaneous sinus floor elevation (SFE) and implant insertion model. Fresh bovine rib samples that resembled type -IV density that were confirmed by computerized tomography were prepared to represent 4 groups of varying RBHs (3, 6, 9, 15 mm). To simulate simultaneous implant insertion with SFE, 120 implants in different macro -designs (group R: NobelReplace; group P: NobelParallel; group A: NobelActive, Nobel Biocare, Gothenburg, Sweden) were randomly inserted at RBHs of 3, 6, 9, and 15 mm in each rib. The implant stability quotient (ISQ) was measured immediately after implant insertion. RBH and implant macro -design have an impact on ISQ values (P < .001). ISQ values were the highest with RBH of 15 mm, followed by RBHs of 9, 6, and 3 mm. (P < .001). There was no statistically significant difference between different implant macro -designs at RBHs of 3 and 15 mm regarding ISQ values (P = .111, P = .551). ISQ values of group P were higher than those of group R and group A at an RBH of 6 mm (P = .049, P = .029). ISQ values were also higher in group P compared to group A at an RBH of 9 mm (P = .006). A higher PS may be expected in sites with higher RBH, regardless of the macro -design. In addition, cylindric implant design may enhance the PS at RBHs of 6 and 9 mm in simultaneous implant insertion with SFE.

Transoral endoscopic assisted reduction and internal fixation of mandibular condylar neck fractures with short condylar segment
(Churchill Livingstone, 2024) Abdelazeem, Mohamed Hazem; Erdoğan, Özgür; Çakır, Merve; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial Surgery
This study aimed to assess the reliability and safety of transoral endoscopic-assisted reduction internal fixation (TERIF) for treating short-segment condylar neck fractures (CNF), including hardware removal. Patients with displaced CNF and short condylar segments treated using TERIF were included in the study. Clinical evaluation covered dental occlusion, range of mouth opening, deviation during mouth opening, protrusion, laterotrusion, pain, and chewing. Radiological evaluation was used to assess fracture displacement, angulation, head dislocation, postoperative reduction, fixation stability, and bone healing. The same technique was used to treat 15 patients with 18 CNF and short condylar segments. Hardware removal was performed for nine fractures in eight patients after fracture healing using the same approach. All patients regained satisfactory, pain-free mouth opening with no deviation and complete bone healing. Computed tomographic images displayed adequate reduction and stable fixation during the follow-up period for all patients. No temporary or permanent facial nerve impairment occurred in any of the patients. TERIF is a reliable and safe treatment for CNF with short condylar segments, even in the presence of head dislocation, medial override, and malunited fractures; hardware can be safely removed after healing using the same approach.

Use of Leukocyte-rich and Platelet-rich Fibrin (L-PRF) Adjunct to Surgical Debridement in the Treatment of Stage 2 and 3 Medication-Related Osteonecrosis of the Jaw
(Lippincott Williams & Wilkins, 2023) Yalcin-Ulker, Gul Merve; Çakır, Merve; Yalçın Ülker, Gül Merve; Meral, Deniz Gökçe; Meral, Deniz Gokce; Ağız,Diş ve Çene Cerrahisi / Oral, Dental and Maxillofacial Surgery
Medication-related osteonecrosis of the jaw (MRONJ) is characterized by exposed necrotic bone persisting for more than 8 weeks in the maxillofacial region in patients using antiresorptive or antiangiogenetic drugs for several treatment options like bone metastasis or osteoporosis. There are several treatment options studied in scientific literature, and one of them with promising results is using platelet concentrates adjunct to surgical therapy. The aim of this study is to examine the therapeutic effect of leukocyte and platelet-rich fibrin (L-PRF) on patients with MRONJ. This 2-centered study investigated patients referred to oral and maxillofacial surgery departments of 2 university clinics between the years 2014 and 2020 with the diagnosis of MRONJ. Demographic data, the indication of the drug usage, drug type, duration, administration route, and systemic comorbidities of the patients were recorded. L-PRF was applied to 20 osteonecrotic lesions of 19 patients following surgical debridement. The male/female ratio was 5/14. Except 1 of the patients, all of the indications of medication were neoplasia-related. The mean follow-up period of patients was 27.9 & PLUSMN;9.2 months. Most common antirezorptive drug was zoledronate (84.2%). Complete resolution was observed in 16 necrosis sites (80%). It could be concluded that the use of L-PRF may represent an important adjunct in the surgical management of MRONJ.
