We investigated the oral stereognostic ability (OSA) of dentate individuals, conventional complete denture patients, and maxillary implant-supported denture patients with bar attachments. Stereognosis tests were carried out, and the relationship between OSA and patient satisfaction was assessed with a satisfaction survey: the Turkish version of the oral health impact profile-14 (OHIP-TR-14). To compare differences in oral sensory function among individuals with natural dentition, complete denture wearers, and maxillary implant-supported denture wearers, tactile awareness (thickness perception threshold) and pressure awareness (threshold of lateral loading) were assessed. According to the results, the oral perception level of natural dentate patients was higher than that of the complete denture group and maxillary implant-supported complete denture group at the end of the study. There was no statistically significant difference in OHIP-TR-14 scores between the maxillary implant-supported complete denture group and the complete denture group ( P < .05). The control group perceived the applied lateral and vertical forces statistically earlier than the other groups ( P < .001). There was no statistically significant difference between the complete denture and maxillary implant-supported denture groups in terms of the lateral pressure threshold or thickness tactile threshold ( P > .05). At the end of the study it was concluded that there was no correlation between oral perception levels and satisfaction in patients with complete dentures and patients with maxillary implant-supported complete dentures. The control group, compared with the complete denture and maxillary implant-supported complete denture groups, perceived the lateral and vertical forces statistically earlier than the other groups.

Aim In this cross‐sectional descriptive study, it was aimed to determine the relationship between the prevalence of temporomandibular disorder (TMD) and oral parafunctions in dental assistant students and to evaluate the effects of gender and education years. Methods The results of 105 individuals (mean age: 20.72 ± 3.51 years; 75 females, 30 males) were analyzed in this descriptive cross‐sectional study, which included student participants who received dental assistant education program from Erciyes University Vocational Health College. The Fonseca Anamnestic Index (FAI) questionnaire was used to define the presence and symptoms of TMD, and the Oral Behavior Checklist (OBC) questionnaire was used to determine the oral parafunctions of individuals. Fisher's exact, Mann–Whitney U, Kendall tau‐b, and Spearman correlation and linear regression analyses were used to evaluate the data. Results Any level of TMD was detected in 64.8% of all individuals included in the study, and most of these patients were women (74.3%). No significant difference was found between the TMD prevalence of the first‐ and second‐grade students based on the years of education of the participants (p = 0.614).   Considering the sex and class parameters, statistically significant weak (r = 0.378 for females; r = 0.375 for the first grade) and middle (r = 0.418 for males; r = 0.478 for the second grade) degree positive correlation was determined (p < 0.01) between the OBC and TMD scores for both parameters. Conclusion The prevalence of TMD is higher in dental assistant students, especially females, and this is associated with certain degrees of oral parafunctions.

This study compared peri-implant vertical bone loss, the periodontal index, prosthodontic maintenance requirements and oral health-related quality of life of patients (OHQoL) using mandibular implant-supported overdentures with two different attachment systems after an average of 5 years of use.16 mandibular overdenture patients with magnet attachments (Group 3), 24 with implant-supported mandibular overdentures with Locator attachments (Group 2), and 25 conventional complete denture patients (Group I) were included in the study. The existing at least 5 years old dentures of all patients were evaluated for prosthodontic maintenance by the same prosthodontist and the patients were administered the OHIP-TR-14 questionnaire. Peri-implant tissue health was evaluated clinically in terms of plaque scores, bleeding scores, probing depth and gingival index. Radiographic evaluation was performed in terms of periimplant vertical bone loss. Radiographic evaluations were performed 5 year after overdenture insertion.There were no statistically significant differences between the groups in terms of total OHIP-TR-14 scores (p &gt; 0.05). While the average vertical bone resorption measured in Group 2 at the end of 5 years was 1.38 mm, there was an average vertical bone loss of 1.45 mm in Group 3, but this difference was not statistically significant (p &gt; 0.05). Among the periodontal health indicators, there were no statistically significant differences in the mean values ​​for periodontal indexes.According to results of the study; there were no differences in peri-implant vertical bone loss in Group2  and 3, in periodontal health in mandibular overdentures with Group2 and 3, or between total OHIP-TR-14 scores of patients in all groups.

Aim: The aim of this study is to compare the diagnosis of patients with temporomandibular joint (TMJ) internal derangements which had been diagnosed using Research Diagnostic Criteria/Temporomandibular Disorders (RDC/TMD) with the dynamic high resolution sonography findings. Settings and Design: Axis I section of RDC/TMD form had been applied to participants. Participants were divided into three groups as healthy TMJ, disc displacement with reduction, and disc displacement without reduction. The diagnoses had been compared with the dynamic high-resolution sonography findings. Materials and Methods: Twelve of the patients had been treated with laser therapy, whereas 13 patients were treated with stabilization splint. Seventeen patients were treated with anterior repositioning splint ( n = 42). After the application of different treatment modalities, the position of the articular disc had been determined with Axis I of RDC/ TMD form and dynamic high-resolution sonography. The findings were compared and statistically analyzed. Statistical Analysis Used: Statistical analyses of data were analyzed with Turcosa Cloud (Turcosa Ltd Co, Turkey). Results: For the right TMJ, pretreatment and posttreatment ultrasonography (USG) diagnoses and RDC/ TMD clinical diagnoses were found similar (κ = 0.125–0.008). No statistically significant relationship was found ( P > 0.05). For the left TMJ, pretreatment USG diagnosis and RDC/TMD clinical diagnose were found similar (κ = 0.070). No statistically significant relationship was found ( P > 0.05). For the left TMJ, posttreatment USG diagnosis and RDC/TMD clinical diagnose were compared. A statistically significant difference was found (κ = 0.256). A statistically significant relationship was found ( P < 0.05). Conclusions: Axis 1 of RDC/TMD form which is used for the diagnosis of internal derangements and dynamic high resolution sonography was not found in the agreement.

Purpose: The aim of this study was to examine the effects of various sintering procedures on the color parameters, marginal, and internal fit of zirconia crowns. Materials and Methods: Overall, 60 zirconia crowns were produced using 3 distinct zirconia blocks (Wieland Zenostar, Zirkonzahn Ice Translucent, and Zirkonzahn Prettau). For the sintering procedure of the crowns, six groups were created as follows: Wieland-Standard, Wieland-Speed, Ice-Standard, Ice-Speed, Prettau-Slow, and Prettau-Standard programs. The crowns were assigned into groups ( n = 10 in each group). The color parameters, marginal fit, and internal fit of the crowns were evaluated. The normality of data distribution was evaluated with the Kolmogrov–Smirnov test. Two independent samples t-test and Mann–Whitney U test were used to compare the sintering groups. Results: Acceleration of sintering caused a significant change in the color parameters of the Wieland and Ice groups but not in the Prettau group. In the Wieland group, marginal ( p = .047) and internal ( p = .004) gap values of speed sintering were found to be significantly lower than those in standard sintering. In the Ice group, the marginal gap values of speed sintering were found to be significantly lower than those in standard sintering ( p = .019). In the Prettau group, the marginal gap values of standard sintering were found to be significantly higher ( p = .035) than those in slow sintering. Conclusions: It was concluded that the effects of sintering procedures on color parameters, and internal and marginal fit of zirconia crowns were clinically insignificant. Speed sintering can be recommended for zirconia restorations.
