“…Intra-oral ceramic restorations are regularly exposed to acid-base changes and temperature fluctuations produced by food and drink consumption. Therefore, in ideal circumstances the dental ceramic restorations should resist or only have minimal changes in such environments [ 35 , 36 ].…”

Erosive beverages cause dissolution of natural teeth and intra-oral restorations, resulting in surface characteristic changes, particularly roughness and degradation. The purpose of this study was to evaluate the surface roughness and topography of a dental ceramic following immersion in locally available erosive solutions. A total of 160 disc specimens of a nano-fluorapatite type ceramic (12 mm diameter and 2 mm thickness) were fabricated and equally distributed into two groups (n = 80) and then evenly distributed among the following five testing groups (n = 16): lemon juice, citrate buffer solution, 4% acetic acid, soft cola drink, and distilled water which served as a control. The surface roughness (Ra) and topography were evaluated using a profilometer and scanning electron microscope at baseline, 24 h, 96 h, and 168 h respectively. Data were analyzed using ANOVA and Tukey’s multiple comparisons (p ≤ 0.05). Surface changes were observed upon exposure to all acidic beverages except distilled water. Amongst all immersion media, 4% acetic acid produced the most severe surface roughness across all time periods (i.e., baseline, 24 h, 96 h, and 168 h). A statistically significant difference in the surface roughness values between all immersion media and across all four time intervals was observed. Erosive agents had a negative effect on the surface roughness and topography of the tested ceramic. The surface roughness increased with increased storage time intervals.

Purpose:The purpose of the present study was to assess the influence of repeated piezoelectric ultrasonic strokes on the marginal leakage of different ceramic cemented crowns. Materials and Methods:Forty human maxillary first premolars received full coverage standardized preparation 1mm above the cemento-enamel junction (CEJ). All teeth were classified into 2 groups (n=20) related to the type of the examined ceramic material; high translucent zirconia (HTZ) and hybrid resin ceramic (HRC). After all the fabricated crowns cementation with selfadhesive resin cement, each group was later partitioned into 4 subgroups (n=5). This was based on the amount of exposed ultrasonic scaler strokes. Microleakage assessment of buccolingual sectioned samples was performed, after their immersion in 2% methylene blue (MB) dye. Stereomicroscope was used for dye penetration measurement. Results:The highest leakage percentage was recorded for HTZ, while the lowest mean value was achieved with HRC. The difference between the two groups was statistically significant (P= 0.022 <.05) as reported by one-way ANOVA. 7 years of scaler strokes for HTZ showed the highest microleakage mean with statistical significant difference p=0.008 between the subgroups. All the subgroups for HRC showed statistical insignificant difference with p=0.728.

“…Improperly constructed "interim" restorations may cause periodontal inflammation and gingival recession and the requirements for fit, polish, and contour in the interim restoration should be the same as for the final restoration. Sometimes, inappropriate prosthetic treatment planning or the prosthesis itself can cause periodontitis or gingival recession [12].…”

An Interdisciplinary Study Regarding the Characteristics of Dental Resins Used for Temporary Bridges

Background and Objectives: The surface condition of the materials that are used for temporary prostheses influences their microbial colonization, with a direct impact on the oral tissues. This study aims at a comparative analysis of three types of resins for temporary bridges using conventional and digital technologies. The attention was focused on the analysis of the surface characteristics and mechanical strength of these materials. Materials and Methods: The surface condition was assessed for three distinct materials both before and after polishing- heat-curing resin Superpont C + B (SpofaDental, Jicin, Czech Republic) used unconventional technology, Zotion dental milling polymethyl methacrylate (PMMA) block (Zotion, Chongqing, China) for provisional crowns/bridges used in digital subtractive technologies and Freeprint Temp (Detax GmbH & Co. KG, Ettlingen, Germany) resin for temporary crowns and bridges that are used in 3D printing technologies. The two-way ANOVA analysis indicated that polishing leads to a statistically significant increase in roughness coefficients for all the three resins that were tested (p < 0.001). While the highest roughness coefficients were displayed in the 3D cured sample, the largest decrease was reported by the milled sample Results: The results revealed that surface roughness was significantly influenced by both the type of resin that was used (p < 0.001) and the treatment that was induced by finishing and polishing (p < 0.001). Similar p-values were obtained for each of the three resins. Conclusions: The results demonstrated a significant optimization of the surfaces after finishing and polishing and statistically significant differences between the surface parameters and the mechanical properties of the samples. The low values of the roughness and the acceptable values of the mechanical resistance for the conventional samples indicate these materials for the long-term temporary bridge’s realization, allowing the correct restoration of the functions and the rehabilitation at the oral level.
