Item In reply to Cheng et al. (DOI: 10.1186/s13550-023-00965-8)(2023) Somay, Efsun; Topkan, Erkan; Pehlivan, Berrin; Selek, Ugur; 0000-0001-8251-6913; 0000-0001-8120-7123; 37589948; AAG-2213-2021Item Systemic Inflammation Score for Predicting Radiation-Induced Trismus and Osteoradionecrosis of the Jaw Rates in Locally Advanced Nasopharyngeal Carcinoma Patients(2023) Somay, Efsun; Sezen, Duygu; Selek, Ugur; Besen, Ali Ayberk; Mertsoylu, Huseyin; Topkan, Erkan; 0000-0001-8120-7123; AAG-2213-2021We sought to determine the predictive value of the systemic inflammation score (SIS) for radiation-induced trismus (RIT) and osteora-dionecrosis of the jaw (ORNJ) in locally advanced nasopharyngeal carcinoma (LA-NPC) patients treated with concurrent chemoradio-therapy (C-CRT). LA-NPC patients (n= 188) who underwent C-CRT and pre-and post-C-CRT oral examinations from August 2010 to January 2022 were included. The three-tiered SIS groups were created using the serum albumin and lymphocyte-to-monocyte ratio (LMR) measures obtained on the first day of C-CRT: SIS-0: Albumin >= 40 g/dL and LMR >= 4.44); SIS-1: Albumin < 40 g/dL and LMR < 4.44 or albumin >= 0 g/dL and LMR >= 4.44; and SIS-2: Albumin < 40 g/dL and LMR <4.44. The primary objective was to ascertain whether there were irrefutable associations between pretreatment SIS groups and the respective post-C-CRT RIT and ORNJ rates. RIT and ORNJ were diagnosed in 33 (17.6%) and 21 (11.1%) patients, respectively. There were 12 (32.4%), 13 (12.7%), and 18 (45.0%) cases diagnosed with RIT in the respective SIS-0, SIS-1, and SIS-2 groups (p< 0.001). Similarly, there were 1 (2.7%), 11 (9.9%), and 9 (22.5%) cases with ORNJ diagnoses in the corresponding SIS groups (p< 0.001). The multivariate analysis's findings revealed that the SIS grouping was an independent predictor of RIT (p< 0.001) and ORNJ incidence rates (p< 0.001). Our study's findings indicate that the novel pretreatment SIS grouping is a dependable biomarker-based system, which can accurately predict the rates of RIT and ORNJ in LA-NPC patients who receive definitive C-CRT.Item In Reply to Bertl et al.(2023) Somay, Efsun; Topkan, Erkan; Selek, Ugur; 0000-0001-8087-3140; 0000-0001-8120-7123; 0000-0001-8251-6913; O-5474-2014; AAG-2213-2021Item Is obesity a problem that threatens oral health in adults?(2021) Yilmaz, Busra; Somay, Efsun; 0000-0003-0633-5648Purpose: Obesity is one of the increasingly negative factors affecting oral and dental health directly or indirectly in many developed and developing countries. The aim of this study was to determine the relationship between obesity and dental problems in adults and to investigate the effect of obesity on oral and dental health. Materials and Methods: 200 patients over the age of 18 who applied with various dental complaints were examined clinically and radiologically. They were classified as 50 healthy females, 50 healthy males, 50 obese females, and 50 obese males according to the body mass index determined by the World Health Organization (healthy individual < 30.0 kg / m(2) and 30.0 kg / m(2) <= obesity individual). Sociodemographic characteristics, dental health status, and data of all patients were examined. Results: A statistically significant relationship was found between obesity and the number of tooth loss, the number of dental caries, educational status, and the frequency of applying to the dentist. Periodontitis was detected at a higher rate in the obesity group (58 %) compared to the control group, but the relationship between obesity and periodontal status was not statistically significant. Conclusion: Dental problems such as tooth loss, the number of dental caries, and periodontitis were higher in the obesity group, and this result showed that obesity threatens oral and dental health. To prevent these problems, there is a need for preventive strategies and increasing awareness of oral and dental health in obese patients.Item High pretreatment systemic immune-inflammation index values are associated with diminished short-term success after temporomandibular joint arthrocentesis procedure(2021) Somay, Efsun; Yilmaz, Busra; 0000-0003-0633-5648; 0000-0001-8251-6913; 34654426Background The systemic immune-inflammation index (SII) has been demonstrated to be a valid biomarker of a patient's immunological and inflammatory state, with the ability to accurately predict outcomes in a variety of disease conditions. In the absence of comparable studies, we intended to examine the relevance of pretreatment SII in predicting the success rates of temporomandibular joint arthrocentesis (TMJA) at 1-week, 1-month, and 6-month periods, defined as maximum mouth opening (MMO) > 35 mm and VAS <= 3. Methods A sum of 136 patients with disc displacement without reduction (DDwo-red) who underwent TMJA was included. For each patient, pre-TMJA SII was calculated as; SII = Platelets x neutrophils/lymphocytes. Additionally, baseline MMO and VAS measurements were recorded for each patient. The success criteria of TMJA included MMO > 35 mm and VAS <= 3. The optimal pre-TMJA SII cutoff that predicts TMJA success was determined using receiver operating characteristic (ROC) curve analysis. The primary endpoint was the link between the pre-treatment SII and TMJA success (simultaneous achievement of MMO > 35 mm and VAS <= 3). Results The median pre-TMJA jaw locking duration, maximum mouth opening (MMO), and visual analog score (VAS) were 7 days, 24 mm, and 8, respectively. The overall TMJA success rates were determined as 80.1%, 91.9%, and 69.1% at 1-week, 1-month, and 6-months, respectively. The results of ROC curve analysis exhibited the optimal SII cutoff at 526 (AUC: 67.4%; sensitivity: 66.7%; specificity: 64.2%) that grouped the patients into two subgroups: Group 1: SII <= 526 (N = 81) and SII > 526 (N = 55), respectively. Spearman correlation analysis revealed a strong inverse relationship between the pretreatment SII values and the success of TMJA 1-week (r(s): - 0.83; P = 0.008) and 1-month, (r(s): - 0.89; P = 0.03). Comparative analyses displayed that TMJA success rates at 1-week (87.7% vs. 69.1%; P = 0.008) and 1-month (96.2% vs. 80%; P = 0.03) were significantly higher in the SII <= 526 than SII > 526 group, respectively, while the 6-month results favored the SII <= 526 group with a trend approaching significance (P = 0.084). Conclusion The current study's findings suggested the SII as a unique independent prognostic biomarker that accurately predicts treatment outcomes for up to 6 months. Trial registration The results of this research were retrospectively registered.Item Confirming the diagnosis of temporomandibular joint disorder by magnetic resonance imaging(2020) Yilmaz, Busra; Somay, EfsunPurpose: The aim of this study was to define the temporomandibular joint complaints of patients with different genders and educational levels and to investigate the accuracy of these complaints with the diagnosis of temporomandibular joint disorder (TJD) with magnetic resonance imaging (MRII). Material and Methods: Temporomandibular joint MRI and clinical examination findings and panoramic radiographs of 99 patients over 18 years of age who applied to the dental clinic between 2011-2018 with the complaint of jaw pain and limited mouth opening are evaluated. The cases which TJD was determined as a result of MRI, are accepted as MRI (+). The ones with the complaints of TJD, but the joint was within normal limits in the MRI, MRI is recorded as (-). Results: There is significant correlation between MRI results and gender but no correlation between MRI results and tooth loss. It is found education level did not have significant effect on the described joint complaints and MRI (+) findings. Conclusion: Women describe temporomandibular joint problems better than men. Even if the level of education is high, patients may not be able to convey their complaints correctly to the physician. Clinical findings should be supported by MRI results in order to diagnose this disease.
