Background Previous studies have shown that pelvimetry can be valuable in predicting surgical difficulties in rectal cancer operations. However, its usability in predicting circumferential resection margin (CRM) involvement remains debatable. This study investigated the factors affecting CRM status and the importance of computed tomography (CT) pelvimetry in predicting CRM involvement in laparoscopic resection of middle and lower rectal cancer.Methodology In this study, we retrospectively investigated the data of 111 patients who underwent a laparoscopic operation for middle and lower rectum cancer at Ankara University Faculty of Medicine, Department of Surgical Oncology between January 2014 and January 2020. The predictive value of CT pelvimetry and other variables on the CRM status was analyzed.Results The following four pelvic parameters differed significantly between the genders: transverse diameter of the pelvic inlet (p = 0.024), anteroposterior diameter of the pelvic outlet (p = 0.003), transverse diameter of the pelvic outlet (p < 0.001), and pelvic depth (p < 0.001). The effect of pelvic anatomic parameters on CRM involvement was not found to be significant. It was found that tumor height from the anal verge (p = 0.004), tumor size (p < 0.001), and gender (p = 0.033) were significant risk factors for CRM involvement. Survival was poor in patients with male gender (p = 0.032), perineural invasion (p < 0.001), and grade 3 tumor.Conclusions In this study, no benefit was found in predicting CRM positivity from CT pelvimetry in the laparoscopic resection of middle and lower rectal cancer. Besides, tumor height from the anal verge, tumor size, and gender were important factors for CRM positivity. Although our study sheds light on this issue, prospective randomized studies with larger sample sizes are needed.
Evaluating the Impacts of Some Etiologically Relevant Factors on Excessive Gingival Display
(2021) Cetin, Mehtap Bilgin; Sezgin, Yasemin; Akinci, Seray; Bakirarar, Batuhan; 33819318
The literature offers limited and even conflicting information on the etiology of gummy smile. Therefore, this study aimed to evaluate smile line, hypermobile upper lip (HUL), altered passive eruption (APE), and short upper lip (SUL) distribution in a group of patients seeking dental treatment and to examine their effects on gummy smile. A total of 501 individuals (265 men, 236 women) were included in the study. The patients were grouped by gingival display, and presence of HUL, APE, and SUL were evaluated. Multivariate Logistic Regression analyses were performed to investigate the impact of possible risk factors on gummy smile. Of the individuals, 173 (34.5%) had a low smile line, 127 (25.3%) had an average smile line, 146 (29.1%) had a high smile line, and 55 (10.9%) were gummy smile patients. Individuals with gummy smile were younger than the individuals with low smile line (P < .001). As for the possible risk factors for gummy smile, age (odds ratio [OR]: 0.936; 95% CI: 0.901 to 0.972; P = .001), HUL (OR: 18.85; 95% CI: 7.82 to 45.44; P < .001), and APE (OR: 8.819; 95% CI: 3.894 to 19.973; P < .001) were found to be significant together. Gender and SUL/upper lip length were not found to have any impact on gummy smile. HUL is the primary factor that increases the probability of having gummy smile, followed by APE as the secondary factor. It seems reasonable to focus on correction of the HUL for treatment in most gummy smile patients.

(2021) Yilmaz, Mediha Nur Nisanci; Bulut, Sule; Bakirarar, Batuhan; 0000-0002-6410-2060; 34478610
Objectives The aim of the study was to investigate the impact of stage-grade of periodontitis and self-reported signs and symptoms on oral health-related quality of life. Methods The diagnosis of periodontitis was based on the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. The Turkish version of Oral Health Impact Profile-14 (OHIP-14) was used to assess oral health-related quality of life (OHRQoL) and the participants were requested to state their symptoms associated with periodontal diseases. Results One hundred and sixty-six patients were included in the study with a mean age of 46.54 +/- 9.24 years. The participants with Stage IV and Grade C periodontitis had the highest total OHIP-14 scores (median 20.00 [min.-max, 3.00-35.00] and median 18.50 (min.-max, 0.00-36.00]; respectively). The OHIP-14 scores (mean +/- SD) were significantly associated with the symptoms of bleeding gums (13.64 +/- 9.39), sore gums (18.00 +/- 10.47), swollen gums (17.42 +/- 10.91), bad breath (15.82 +/- 9.44), loose teeth (20.00 +/- 8.66) and drifting teeth (24.56 +/- 8.46). Conclusions This study demonstrates a significant association between OHRQoL and periodontitis. Stage-grade of periodontitis and its symptoms were associated with poor quality of life.
The relationship between body mass index and stage/grade of periodontitis: a retrospective study
(2021) Cetin, Mehtap Bilgin; Sezgin, Yasemin; Onder, Canan; Bakirarar, Batuhan; 34709456
Objectives Possible impact of obesity on stage and grade of periodontitis has never been investigated before. This study aimed to examine the association between body mass index (BMI) and stage/grade of periodontitis per the current classification of periodontal diseases. Material and methods A total of 142 patients (82 males/60 females) were included in this study. "2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions" was taken as basis to characterize the stage/grade of periodontitis. Age, gender, smoking status, and frequency of tooth brushing, and medical data of the patients including hypertension, hyperlipidemia, BMI, and diabetes mellitus were obtained from the patient's hospital records. Obesity was assessed by BMI using the "World Health Organization" criteria. For estimating the association between BMI and periodontitis, logistic regression analysis was utilized. Results BMI was statistically associated with clinical attachment loss (CAL), probing pocket depth (PPD), Plaque index (PI), stage and grade of periodontitis, and number of remaining teeth (p < 0.001, p < 0.05, p < 0.05, p < 0.05, p < 0.001, respectively). According to the multiple regression analysis results, those with BMI 25-29.9 were found to be at risk of being stage III-IV 3.977 times (95% CI: 1.831-8.640, p < 0.001) higher than those with BMI < 25, and similarly, those with BMI >= 30 were found to be at risk of being stage III-IV 4.062 times (95% CI: 1.315-12.549, p = 0.015) higher than those with BMI < 25. No relationship was found between obesity and grade of periodontitis according to multivariate analysis. Conclusions BMI increases the likelihood of stage III and stage IV periodontitis; however, it does not have an impact on the grade of periodontitis.
