Materials and Methods: We analyzed 28 SB patients among 210 patients with IFP complaints. The profiles were evaluated using patient charts including gender, age, pain duration, pain location, pain intensity and affected areas by pain. Results: SB with IFP occurred more often in females (85.7%) than males (14.3%). The mean age at presentation was 48.9 years. The most common IFP sites of SB patients were the right maxilla (28.6%) and the right mandible (25.0%). The pain complaints occurred mostly in 2 teeth or areas (50.0%), followed by 1 area (28.6%) and then in ≥ 3 teeth or areas (21.4%). The mean pain intensity was 5.9 on a visual analogue scale from 0 to 10. The pain was spontaneous in 20 patients (71.4%), and the mean pain duration was 24.4 months. Conclusion: Identification of clinical characteristics of SB patients with IFP could be useful in the diagnosis of various IFP patients and beneficial in decreasing unnecessary care to reduce IFP. Further studies with larger number of subjects and extended duration are required for more systemized diagnostic methods and development of future treatment guidelines.

After immersing specimens in the coffee solution and the wine solution, the color was measured as CIE Lab with a colorimeter weekly for 4 weeks. Color change was calculated and data were analyzed with one-way ANOVA and the Tukey multiple comparisons test (α = 0.05). Results: PMMA provisional prosthetic materials by subtractive manufacturing showed superior color stability compared to bis-acryl provisional prosthetic materials by additive manufacturing ( P < 0.05), and showed similar color stability to the PMMA provisional prosthetic materials by conventional method ( P > 0.05). Conclusion: It is recommended to fabricate provisional restorations by subtractive manufacturing in areas where esthetics is important, such as anterior teeth, and consideration of the color stability will be required when making provisional prosthetic using additive manufacturing.

Excessive gingival display also known as “gummy smile” is often recognized to be unaesthetic. Causes of gummy smile can be caused by delayed eruption, vertical maxillary excess, hypermobile upper lip, or a short upper lip. Meanwhile botulinum toxin which is an exotoxin produced from Clostridium botulinum, works by blocking the release of acetylcholine from the cholinergic nerve end plates leading to inactivity of the muscles. The application site and weakens the muscle tone is drawing attention as a gummy smile treatment caused by hypermobile upper lip. There have been many studies about the method of injecting botulinum toxin into muscles around the lips, but there is still no standardized research method and treatment method, so there is controversy over the therapeutic effect. The aim of this study is to review the previous studies about the predictors of indication and effects of gummy smile treatment using botulinum toxin injection. Especially we tried to propose a protocol for optimal dose and efficient injection point through the anatomical considerations for gummy smile treatment using botulinum toxin.

Materials and Methods: The prepared zirconia disks were treated with hydrofluoric acid solution and photo-assisted etching under various condition. The surface was analyzed by SEM and the surface roughness was analyzed by using surface profiler. The osteogenic effect of MC3T3-E1 cells was assessed via fluorescent staining observation and reverse transcriptase-polymerase chain reaction (RT-PCR). Results: Various roughness were obtained according to the surface treatment method. The surface roughness increased in the group treated with hydrofluoric acid solution, but that had week network structure. In the method using photo-assisted etching, the surface roughness increased in micro units. Cell reaction showed better results in the photo-assisted etching group than in the hydrofluoric acid-treated group ( P < 0.05). And it showed even osteoblastic cell distribution in photo-assisted etching group. Conclusion: As a result, the photo-assisted etching method is more effective than the simple acid solution treatment for zirconia treatment for osseointegration.

Compared to milling processing, AM consumes less equipment and materials, making sustainability an advantage. AM can be categorized into 7 types. Polymers made by vat polymerization are the most suitable material for AM due to superior mechanical properties and internal fit compared to conventional self-polymerizing methods. However, polymers are mainly used as provisional restoration due to their relatively low mechanical strength. Metal AM uses powder bed fusion methods and has higher fracture toughness and density than castings, but has higher residual stress, which requires research on post-processing methods to remove them. AM for ceramic use vat polymerization of materials mixed with ceramic powder and resin polymer. The ceramic materials for AM needs complex post-processing such as debinding of polymer and sintering. The low mechanical strength and volumetric accuracy of the products made by AM must be improved to be commercialized. AM requires more research to find the most suitable fabrication process conditions, as the mechanical properties and surface of any material will vary depending on the processing condition.
