“…HF acid etching modifies the morphology of the ceramic by the dissolution of the glassy matrix, resulting in microporosities on the ceramic surface (3,4,14-16), improve bond strength (3,4,16,17), and better contact between bonding material and ceramic (18,19). However, HF acid is a toxicity, corrosiveness and reactivity inorganic acid (8) and can lead to several health complications for patient and dental personal (6,20). The severity depends on the acid concentration and exposure time, and penetration to the exposed tissue (6).…”

This study to evaluate the effects of different hydrofluoric acid (HF) concentrations and thermal cycling on the shear bond strength (SBS) of brackets to ceramic. Cylinders of ceramic were divided into 10 groups (n=15), according to HF concentrations: 1-1%;2-2.5%;3-5%;4-7.5%;5-10% (storage 24 h); 6-1%;7-2.5%;8-5%;9-7.5%; and, 10-10% (thermal cycling). All cylinders were etched for 60s and received one layer of silane. Metallic brackets were bonded to the cylinders using Transbond-XT, light activated for 40 s, using a LED (Radii Plus) and stored in deionized water at 37o C for 24h. The groups 6 to 10 were submitted to thermal cycling (7,000 cycles - 5o/55oC). SBS was performed in an Instron at crosshead speed of 1.0 mm/min. Data were submitted to two-way ANOVA and Tukey’s post-hoc test (α=0.05). The Adhesive Remaining Index (ARI) was evaluated at 40x magnification. The different HF acid concentrations influenced on the SBS of the brackets to ceramic (p<0.05). The thermal cycling decreased the SBS of the brackets to ceramic for all acid concentrations (p<0.05). The ARI showed a predominance of scores 0 for all groups, with an increase in scores 1, 2 and 3 for the group storage for 24 h. In conclusion, the different HF acid concentrations 5.0%, 7.5% and 10% influenced on the SBS of brackets to ceramic. The thermal cycling decreased significantly the SBS of brackets to ceramic.

“…In some situations, the electrolyte imbalance has to be modified, and malignant ventricular arrhythmia or even death can occur. 18 Coffey and colleagues 19 evaluated the effectiveness of calcium and magnesium in the treatment of oral fluoride poisoning using a porcine model. The results indicated that calcium and magnesium had a protective effect against the systemic effects of HF, and pigs that received calcium and magnesium lived longer and required larger amounts of HF to produce QRS prolongation and fatality compared with the untreated group.…”

Hydrofluoric acid (HF), a dangerous inorganic acid, is widely used in various industries and in daily life. Chemical burns caused by HF exposure occur more frequently in some regions worldwide. It has been reported that some cases with HF burns can be lethal due to the hypertoxicity of HF. In this article, we present a case of a 24-year-old worker who suffered HF burns by 53% HF solution to his face, neck, and nasal cavity. This patient quickly developed electrolyte disturbance, that is, hypocalcemia, and hypopotassemia, and myocardial injury after exposure. Multiple measures had been taken to treat this patient, including fluid resuscitation, electrolyte replacement, timely wound treatment with neutralizers, and respiratory tract care. Moreover, continuous renal replacement therapy was also employed to remove fluoride in the circulatory system and rectify the electrolyte disturbance and acid-base imbalance. The patient smoothly pulled though and survived. High fluoride levels in the dialysate solution were confirmed, indicating that continuous renal replacement therapy is an effective and potentially lifesaving treatment for acute HF poisoning.
