The present study was designed to evaluate the effects of low-level laser (Nd:YAG) therapy and occlusal splints in patients with signs and symptoms of temporomandibular disorders (TMD) characterized with myofascial pain (MP). A total of 30 patients were selected after being diagnosed with MP according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TDM). The patients were divided into three groups. The first group was occlusal splint (OS) group A (n = 10), the second was low-level laser therapy (LLLT) group B (n = 10), and the last group C was placebo (n = 10). LLLT (1,064 nm, 8 j/cm(2), 250 mW, Fotona) was applied to the patients in the study group once a day for 10 days, for a total of ten sessions. The same parameters and application times were used for placebo group, but the patients were not irradiated. The application was on the trigger points. The patients in the OS group were instructed to wear occlusal splints 12 h/day for 3 weeks. Functional examination was based on RDC/TDM, and pressure pain values were obtained with the Visual Analog Scale. Comparisons were made between the groups before and after the treatment according to Wilcoxon, Mann-Whitney U, and Kruskal-Wallis tests. The pain score values decreased significantly after both LLLT (p < 0.05) and occlusal splint therapy (p < 0.05) compared to placebo group (p < 0.05). There was no significant difference between LLLT and OS groups after treatment (p > 0.05). OS and LLLT are effective for decreasing MP. In addition, this particular type of LLLT is as effective as occlusal splint for pain relief.
Objective:The purpose of this retrospective study was to analyze clinic and radiologic features and the prevalence of jaw cysts in southeast region of Turkey.Materials and Methods:This study was carried out in 149 cysts of the jaw diagnosed among 407 individuals who were taken biopsy in our department from October 2008 to December 2012. All cysts were treated by enucleation, marsupialization, or combination, and all cases were histologically examined.Results:One-hundred-and-forty-eight cases were classified odontogenic, one was non-odontogenic. There were 89 cysts (59.7%) in men, 60 (40.3%) in women. The mean age was 32.72 years. We found 80 cysts (35 F, 45 M) in the maxillary and 69 (28 F, 41 M) in mandible. It is observed that 94 were radicular cysts (63%), 40 were dentigerous cysts (26.9%), 9 were odontogenic keratocysts (OKC) (6.1%), 5 were residual radicular cysts (3.4%), and 1 was nasopalatine cyst (0.6%). In radicular cysts, 56 of them (59.5%) were located in the anterior region of the jaws; 18 dentigerous cysts and 2 OKCs were found in the posterior region of mandible. Clinically, the chief complaint of patients was expansion and pain. Radiographically, scalloping of the lesion between the teeth was found in 1 case, root resorption was seen in 3 cases, and displacement of the teeth and follicles was observed in 16 cases.Conclusions:We found similar prevalence of jaw cysts that reported in the literature, in which most odontogenic cysts (OCs) were inflammatory origin.
The aim of the study was to determine the possible predictive value of certain patient- and stone-related factors on the stone-free rates and auxiliary procedures after extracorporeal shock wave lithotripsy in patients with impacted proximal ureteral calculi. A total of 111 patients (86 male, 25 females M/F: 3.44/1) with impacted proximal ureteral stones treated with shock wave lithotripsy were evaluated. Cases were retrieved from a departmental shock wave lithotripsy database. Variables analyzed included BMI of the case, diameter of proximal ureter and renal pelvis, stone size and Hounsfield unit, ureteral wall thickness at the impacted stone site. Stone-free status on follow-up imaging at 3 months was considered a successful outcome. All patients had a single impacted proximal ureteral stone. While the mean age of the cases was 46 ± 13 years (range 26-79 years), mean stone size was 8.95 mm (5.3-15.1 mm). Following shock wave lithotripsy although 87 patients (78.4%) were completely stone-free at 3-month follow-up visit, 24 (21.6%) cases had residual fragments requiring further repeat procedures. Prediction of the final outcome of SWL in patients with impacted proximal ureteral stones is a challenging issue and our data did clearly indicate a highly significant relationship between ureteral wall thickness and the success rates of shock wave lithotripsy particularly in cases requiring additional procedures. Of all the evaluated stone- and patient-related factors, only ureteral wall thickness at the impacted stone site independently predicted shock wave lithotripsy success.
Both the Nd:YAG and 810 nm diode lasers were effective for the treatment of subjective tinnitus related to TMDs.
Purpose:To evaluate the patient and stone related factors which may influence the final outcome of SWL in the management of ureteral stones.Materials and Methods:Between October 2011 and October 2013, a total of 204 adult patients undergoing SWL for single ureteral stone sizing 5 to 15 mm were included into the study program. The impact of both patient (age, sex, BMI,) and stone related factors (laterality, location, longest diameter and density as CT HU) along with BUN and lastly SSD (skin to stone distance) on fragmentation were analysed by univariate and multivariate analyses. Results: Stone free rates for proximal and distal ureteral stones were 68.8% and 72.7%, respectively with no statistically significant difference between two groups (p=0.7). According to univariate and multivariate analyses, while higher BMI (mean: 26.8 and 28.1, p=0.048) and stone density values (mean: 702 HU and 930 HU, p<0.0001) were detected as statistically significant independent predictors of treatment failure for proximal ureteral stones, the only statistically significant predicting parameter for the success rates of SWL in distal ureteral stones was the higher SSD value (median: 114 and 90, p=0.012).Conclusions:Our findings have clearly shown that while higher BMI and increased stone attenuation values detected by NCCT were significant factors influencing the final outcome of SWL treatment in proximal ureteral stones; opposite to the literature, high SSD was the only independent predictor of success for the SWL treatment of distal ureteral stones.
We aimed to evaluate the effect of shift work on semen parameters together with the effect of sleep quality in men attending infertility clinic. The participants were divided into two groups as follows: 104 shift worker men (Group 1) and 116 nonshift worker men (Group 2). Groups were compared in terms of semen parameters, Depression Anxiety Stress Scale-21 (DASS-21), and Pittsburg Sleep Quality Index (PSQI) scores. A higher rate of oligozoospermia and poor sleep quality and a lower mean normal morphology percentage was observed in shift workers than nonshift workers (p = .006, .039 and .036 respectively). In addition, a positive correlation was seen between sleep duration and sperm concentration, while a negative correlation was found between sleep latency and total sperm count. Shift working together with high PSQI score was also a significant association with oligozoospermia when controlling for the other variables of age, total testosterone, DASS-21 stress score, smoking and varicocele (OR = 2.11, 95% CI 1.03-4.34 and OR = 1.18, 95% CI 1.01-1.39 respectively). In this study, infertile shift workers had a lower percentage of normal morphology and higher rates of oligozoospermia and poor sleep quality.Considering that shift workers have lower sleep quality, it seems that shift working negatively affects the circadian rhythm. K E Y W O R D S semen parameter, shift work, sleep quality 2 of 7 | DEMIRKOL Et aL.shift work can undermine sleep quality by interfering with the body's natural circadian rhythm. Likewise, it was shown in a study that shift work is an independent risk factor for poor sleep quality (McDowall et al., 2017). Furthermore, shift work has been related to several health outcomes, including metabolic disorders, cardiovascular disease, mood disorders, as well as male reproductive disorders (Bara & Arber, 2009;
In the present study, the changes that occur in rat liver tissue as a result of the use of grape seed extract (GSE) and low level laser therapy (LLLT) in intraoral wound (IW) healing are analyzed using biochemical parameters. Diode laser application groups received 8 J/cm dose LLLT once a day for 4 days (810 nm wavelength, continuous mode, 0.25 W, 9 s). As a result of the biological parameter analysis, it was determined that the oxidative damage caused by the IWs and recovery period on 7th and 14th days could be substantially removed with GSE applications that have antioxidant capacity especially in rat liver tissue. In addition, the active compound of grape seed, catechin is studied in the active site of glycogen synthase kinase 3 (GSK3) target using molecular modeling approaches. Post-processing molecular dynamics (MD) results for catechin is compared with a standard GSK3 inhibitor. MD simulations assisted for better understanding of inhibition mechanism and the crucial amino acids contributing in the ligand binding. These results along with a through free energy analysis of ligands using sophisticated simulations methods are quite striking and it suggests a greater future role for simulation in deciphering complex patterns of molecular mechanism in combination with methods for understanding drug-receptor interactions.
Objective: Until recently, most reports about transmigration have documented that the canine is the only tooth which can migrate to the opposite side of the arch. The goal of the study was to define the transmigration of different types of teeth in people in various regions of Turkey. Study Design: A total of 112,873 panoramic radiographic files from seven different Turkish cities were inspected. The following data were evaluated according to age, gender, number of transmigrant teeth, localization, eruption status, side, unilaterally or bilaterally and associated pathology or dental abnormalities. Results: Of the 112,873 radiographs included in the study, 90 were seen to present as transmigrant in 87 patients, representing 0.079% of the sample. There were only two (0.0017 %) transmigrant lateral (TML) teeth and only three (0.0026%) transmigrant premolar (TMP) teeth encountered. The mean age at the time that the transmigrant mandibular teeth were identified was 29.9 years, with a range from 10 to 66 years. Out of the 87 cases, 51 were female and 36 were male, with a male:female ratio of 1:1.41. Transmigrants were more commonly seen unilaterally (96.5%). The most frequent associated pathology was odontoma. Conclusions: Because early detection is vital to prevent complications and ensure more successful treatment, these extensive studies are crucial. In this extensive study, we indicated cases of transmigration of premolar and lateral teeth as a variant. Demographic variables and properties of all transmigrants (TM) were also presented.
