Soft drinks and dental erosion during pediatric age: a clinical investigation

Eating Disorders and Dental Erosion: A Systematic Review

Both eating disorders and dental erosion are increasingly affecting adolescents and young adults. Thus, our systematic review was designed to answer the question: "Is there a relationship between dental erosion and eating disorders?" Following the inclusion and exclusion criteria, 31 studies were included in this systematic review (according to the PRISMA statement guidelines). Based on the meta-analysis, 54.4% of patients with bulimia nervosa and 26.7% with anorexia nervosa experienced tooth erosion. For the whole group of 1699 patients with eating disorders, erosive lesions were observed in 42.1% of patients. Bulimics were more than 10 times more likely to experience dental erosion compared to healthy individuals (OR = 10.383 [95%CI: 4.882-22.086]). Similarly, more than 16 times increased odds of tooth erosion were found in patients with self-induced vomiting (OR = 16.176 [95%CI: 1.438-181.918]). In conclusion, eating disorders are associated with an increased risk of developing erosive lesions, especially in patients with bulimia nervosa.

Inhibition of Citric Acid-Induced Dentin Erosion by an Acidulated Phosphate Sodium Monofluorophosphate Solution

Sodium monofluorophosphate (Na2FPO3, MFP) is mainly used as an ingredient in fluoride-based dentifrices as it has a high safety profile, with one-third of the toxicity of sodium fluoride (NaF), as well as the ability to reach deep into the dentin. The purpose of this study was to assess the prevention of dentin erosion by MFP upon exposure to citric acid, which has a chelating effect, and to compare the effects to those of the conventional acidulated phosphate fluoride (APF) application method. Bovine dentin was used, and four groups were created: (i) APF (9000 ppmF, pH 3.6) 4 min group; (ii) acidulated phosphate MFP (AP-MFP, 9000 ppmF, pH 3.6) 4 min group; (iii) AP-MFP 2 min + APF 2 min (dual) group; and (iv) no fluoride application (control) group. Compared with the conventional APF application method, the application of AP-MFP was shown to significantly reduce substantial defects, mineral loss, and lesion depth; better maintain Vickers hardness; and promote the homogenous aggregation of fine CaF2 particles to seal the dentin tubules, enhancing acid resistance in their vicinity. The ΔZ value of the AP-MFP group was 2679 ± 290.2 vol% μm, significantly smaller than the APF group's 3806 ± 257.5 vol% μm (p < 0.01). Thus, AP-MFP-based fluoride application could effectively suppress citric acid-induced demineralization and could become a new, more powerful, and biologically safer professional-care method for preventing acid-induced dentin erosion than the conventional method.

Postoperative Pain of Pediatric Patients Undergoing Dental Treatment under General Anesthesia Visiting a General Hospital: A Cross-Sectional Study

Dental general anesthesia (GA) is a day-stay procedure and is a suitable choice for complicated cases. It is undertaken in a controlled hospital setting that ensures the quality, safety, efficacy, and efficiency of dental treatment. The purpose of this study is to determine the prevalence, severity, duration, and factors related to the occurrence of postoperative discomfort in young children following GA in a general hospital. This study includes a minimum sample size of 23 children that were undergoing GA over a 1-month period. Informed consent was obtained from the parent prior to the treatment. A preoperative questionnaire via the Survey Monkey program was used for the purposes of recording the responses of the survey population. All data related to the immediate postoperative period while the child was in the post-anesthetic recovery room (PAR) was collected and assessed by one of the investigators using the Face, Legs, Activity, Cry, and Consolability (FLACC) pain assessment scale. Postoperative data was gathered using the Dental Discomfort Questionnaire (DDQ-8) and was performed by phone 3 days after the GA procedure. The participating 23 children ranged from 4 to 9 years old (mean 5.43 ± 1.53). A total of 65.2% were girls and 34.8% were boys, with 30.4% experiencing a recent history of pain.
