“…Low pH in a solution containing the dental restorative material has been reported to affect its optical and surface properties . In the present study, the conventional mouthwash had a relatively low pH (3.93 ± 0.02).…”

“…Therefore, the optical and surface properties of these materials can change within the oral cavity. Several studies have reported that acidic solutions, including cola, orange juice, red wine, coffee, and gastric acid, can change the optical properties and surface roughness of tooth‐coloured dental restorative materials . In addition, several oral hygiene solutions currently on the market can also affect the colour of dental restoration materials .…”

High‐translucency restorative materials are commonly used in the restoration of anterior teeth where aesthetics is a critical factor. In this in vitro study, the impact of mouthwash on the colour stability and surface characteristics of high‐translucency computer‐aided design and computer‐aided manufacturing (CAD‐CAM) dental restorative materials was evaluated. Two‐hundred specimens were fabricated from five high‐translucency CAD‐CAM materials: a resin nano ceramic; a polymer‐infiltrated ceramic network; a feldspathic ceramic; a lithium disilicate glass ceramic; and high‐translucency zirconia. Each group of ceramic specimens was then divided into four subgroups: conventional mouthwash (LISTERINE); whitening mouthwash (LISTERINE Healthy White); chlorhexidine gluconate; and distilled water. Oral rinsing was simulated at 100 rpm for 180 h, representing 15 yr of clinical simulation. The specimens were then evaluated for colour, translucency, gloss, roughness, and surface morphology. Two‐way ANOVA and linear mixed models were used for intergroup comparisons (α = 0.05). The polymer‐infiltrated ceramic network and feldspathic ceramic became brighter, more opaque, less glossy, and rougher after rinsing with the whitening mouthwash. The long‐term use of specific mouthwashes can cause deterioration of the optical and surface properties of high‐translucency CAD‐CAM dental restorations.

“…It has also been reported that exposure to acids can lead to accelerated abrasive wear of CAD/CAM machinable ceramics and veneering ceramics . A recent study evaluated the effect of gastric acid on monolithic zirconia and found that monolithic zirconia materials show some surface alterations in an acidic environment with minimum effect on their optical properties . While ceramics have evolved to demonstrate superior optical and functional properties over the last few decades, whether these properties are affected by acidic oral environments has yet to be answered.…”

Background: To describe the characteristics, treatments, and prognosis of pediatric gastric perforation patients beyond neonatal period. Methods: Twenty pediatric patients beyond neonatal period were included in this study. Medical records were reviewed and clinical characteristics were analyzed. According to the outcomes, patients were divided into the survival group and the death group. Death time was documented, and survival patients were followed up. The degree of severity was calculated using pediatric critical illness score (PCIS). Differences between the two groups were analyzed by the Student's t-test, Mann-Whitney test and Chi-square test appropriately. Results: Gastric perforation was diagnosed in 20 pediatric patients beyond neonatal period, including 6 males (30%) and 14 females (70%), with the age of 37.18 (15.90, 107.12) months, and the range was from 4.30 months to 14.17 years old. They had different manifestations, etiologies, sites of perforation and surgery procedures. Among the 20 cases, 14 (70%) survived and 6 (30%) died. Age, gender, length and number of perforation had no statistically difference between the two groups. However, PCIS, ischemia of gastrointestinal wall, and transmural necrosis of gastric wall were statistically different. For the survival group, during a follow-up period of 50 (36, 68) months, ranging from 2 months to 8 years and 7 months, one patient had a second-time perforation, another 3 patients had brain injury symptoms, and the rest 10 patients had good quality of lives.Conclusions: Gastric perforation of pediatric patients beyond neonatal period causes a mortality of 30% on this study. Spontaneous great curvature of gastric wall perforation has the highest morbidity. Low PCIS predicts for unfavorable prognosis. Most of the survival patients have satisfactory living quality after operation.
