Analysis Of Gingival Display During Static And Dynamic Smiles In A Turkish Sample: A Clinical Study
(2022) Arifagaoglu, Ozge; Yilmaz, Umran; 35478707
Purpose The aim of this study is to determine the prevalence of smile types in spontaneous smiles among a Turkish population aged 18-23 and to compare it with the prevalence of static smiles. Materials and Methods This study was carried out with 150 undergraduate students at Baskent University Faculty of Dentistry (75 females, 75 males). For this purpose, photo recordings for static smiles and 20-second video recordings for dynamic smiles were taken 40 cm from the participant's nose. Measurements were made with an electronic ruler. Results High smile line was found to be the highest prevalence in both static and dynamic smiles (p<0.001). The average soft tissue display is higher in dynamic smiles (p<0.05). In both static and dynamic smiles, the average amount of gingival display was higher in females than in males (p<0.05). Conclusion When the smile line was evaluated on the photograph recordings while the patient was posing, it was found to be lower than the natural spontaneous smile line obtained from the video recordings. Since the gingival display increases when patients smile naturally instead of posing, clinical evaluations and restorative considerations should be planned according to the dynamic smile.
Effect of the COVID-19 Pandemic on Anxiety in Patients with Masticatory Muscle Pain

Statement of problem. Although psychological disorders have been established as one of the etiological factors for temporomandibular disorders, anxiety levels in individuals with masticatory muscle pain before and during the coronavirus 2019 (COVID-19) pandemic have not previously been compared.Purpose. The purpose of this clinical study was to evaluate anxiety levels in patients with masticatory muscle pain at times before and during the COVID-19 pandemic.Material and methods. Eighty patients (18 to 68 years) with masticatory muscle pain were included in the study. All participants had completed the Generalized Anxiety Disorder 7 questionnaire (GAD-7) before the first COVID-19 infection had been reported in Turkey. After the onset of the COVID-19 pandemic, all participants were contacted by telephone to repeat the GAD-7 to evaluate changes in their psychology during the first lockdown. However, 18 of the 80 patients were unreachable. A statistical analysis was performed by using the Mann-Whitney U test. Proportion comparisons between sociodemographic characteristics and GAD-7 levels were performed by using the Fisher exact test (a=.05).Results. Forty-eight (60%) of the study population were women, and 32 (40%) were men, with a mean age & PLUSMN;standard deviation of 36.63 & PLUSMN;13.85 years. Both before and during the pandemic, GAD-7 scores were statistically similar as was each demographic parameter, including sex, educational status, and occupational status (P>.05). Also, no significant correlation was recorded between age and GAD-7 global scores obtained before and during the pandemic (r=-0.098 and r=-0.052, respectively, P>.05). However, during-pandemic GAD-7 scores were statistically higher than before-pandemic GAD-7 scores (P<.001).Conclusions. Demographic parameters had no connection with anxiety levels in patients with masticatory muscle pain before and during the COVID-19 pandemic. However, the COVID-19 pandemic anxiety levels in the participants were higher than the levels before the pandemic. (J Prosthet Dent 2023;130:74-9)
An investigation of the effect of surface characterization on Saos-2 cell proliferation after coating of titanium alloy surfaces by a selective laser melting process

Pure titanium alloys are commonly employed in construction of dental implants, given their advantageous features including resistance to corrosion, mechanical strength, flexibility, and bioavailability. The purpose of this study was to evaluate the surface characteristics of Ti6Al4V alloy disks upon sand-blasted, large-grit acid-etching, and/or selective laser melting applications and to assess whether and how these surface modifications affect the attachment, viability, metabolic activity, and osteoblastic differentiation of Saos-2 osteosarcoma cells. We manufactured Ti6Al4V alloy disks and divided them into four groups (non-treated, SLA-treated, Ti6Al4V ELI alloy-coated (SLM treated), and SLM+SLA-treated). The topographic analysis was carried using AFM and SEM and chemical content was evaluated by EDX. EDS. Adherence and viability of Saos-2 cells seeded onto disks were investigated via SEM and fluorescent microscopy. To assess the metabolic activity of Saos-2 cells, MTT assay was conducted and the osteoblastic differentiation interpreted via monitoring alkaline phosphatase activity. According to data acquired using AFM and SEM, the control group had the smoothest surfaces, with a lower Ra value. The roughest surface was obtained with SLM and SLA dual-treated disks. The osteoblastic activity of Saos-2 cells on the surface of dual-treated disks was higher than the other groups. Therefore, the surface of SLM+SLA-treated disks conferred a suitable environment for Saos-2 cells to adhere, proliferate, and show higher metabolic activity. We concluded that Ti6Al4V alloy disks covered with Ti6Al4V ELI alloy and subjected to SLA surface treatment may be promising to manufacture dental implants with improved adaptability, bioavailability, and osseointegration.
