Square-shaped specimens that were 0.3 mm, 0.6 mm and 0.9 mm thick, respectively, were fabricated with the Styleveneers (n=30). The color coordinates (CIE L* a* b*) of the specimens were measured before and after glazing with a colorimeter. For a comparison between the `not glazed` and `glazed` groups and among the thicknesses, data were analyzed with a paired T-test, oneway ANOVA test and multiple regression analysis using SPSS 18.0 (p=0.05). The translucency parameter (TP) of the 0.3 mm- and 0.6 mm-thick specimens showed statistically significant differences before and after the glazing process. The one-way ANOVA of color difference (ΔE*) and change of color coordinate (ΔL*, Δa*, Δb*) were statistically different among samples of different thicknesses. The result of the multiple regression analysis showed that Δb*, ΔL* improve ΔE*. Within the limitations of this study, we conclude that the glazing step changes the translucency of 0.3 mm- and 0.6 mm-thick specimens and the color of lithium disilicate laminate ceramic veneers.

Its nonspecific manifestations, such as orofacial pain or joint sounds upon mouth opening, are difficult to distinguish from the symptoms of conventional temporomandibular joint disorders (TMD). This paper reports a 22-year-old female having primary complaint of pain and mouth opening limitations in the left TMJ. She was referred from local clinics, after two years of treatments for TMD had failed. Computed tomography revealed conglomerated calcified bodies in the superior joint space of the left TMJ. Open surgery was performed successfully under general anesthesia, and a total of 124 calcified masses were removed from the joint. The histopathological findings confirmed synovial chondromatosis. Postoperatively, improvement was observed in the patient`s symptoms.

This study investigated the correlation between tooth loss (the chief clinical parameter of periodontal disease) and systemic biomarkers of CVD, C-reactive protein (CRP) levels, and leukocyte (WBC) counts, in Koreans aged 50 years or older. A cross-sectional data of 5,322 participants was obtained from the 2008 to 2010 Dong-gu Study. Oral examination, survey questionnaire, physical examination, and biochemical assessments were performed. Oral examinations were completed in all dentate participants, and included the percentage of sites with ≥ 4 mm of probing depth (PD4%), clinical attachment level ≥ 4 mm (CAL4%), and bleeding on probing (BOP%). The number of missing teeth was categorized as 0-7, 8-15, 16-31, and edentulous. The serum CRP levels and WBC counts were assessed. Multivariate linear regression analysis was performed after adjusting for other potential confounders, to evaluate the association between the clinical parameters of periodontal disease, CRP levels and WBC counts. In the fully adjusted model, PD4%, BOP% and the number of missing teeth positively correlated with the CRP levels (p < 0.05), but CAL4% did not. The PD4%, CAL4%, and BOP% (p < 0.05) were concomitant with the WBC counts, but the number of missing teeth was not. The clinical parameters of periodontal disease and tooth loss directly correlated with CRP levels and WBC count in adults aged 50 years and above. This association indicates the potential significance of periodontal inflammatory burden for systemic inflammation.

However, imperfect regeneration, such as paresthesia, numbness, and painful pathologic regeneration can occur in some cases. Therefore, iatrogenic nerve damage should be avoided during implant placement in patients with alveolar bone atrophy. For placement of implants in the posterior area of the mandible, the corresponding anatomical structures including the inferior alveolar nerve are of concern. Herein, we presented a case of a patient who developed traumatic neuroma after undergoing full mouth rehabilitation with implants in another hospital. Treatment at our facility included the removal of all implants posterior to the mental foramen, followed by an autogenous iliac bone graft performed on the atrophied alveolar ridge of the mandible. Subsequently, implants were placed in the grafted sites. Finally, the patient showed functional and esthetic results.
