    Root canal perforations are frequent but critical complications in endodontic treatments, which can pose a risk of irreversible damage to the affected tooth. These perforations typically occur during root canal preparation or endodontic post placement, presenting significant therapeutic challenges. The main objective in the management of such complications is to seal the perforation, thus preventing bacterial invasion and tooth loss. This report details the case of a 70‐year‐old patient with a perforation in the palatal wall of the middle root section of tooth #11. The treatment approach involved magnification techniques and the application of a bioactive material known as Biodentine. This case underscores the critical role of accurate radiographic evaluation and the use of biocompatible materials in the management of root perforations. Despite inherent challenges, proper diagnosis and planning, combined with appropriate techniques and materials, can lead to satisfactory results, effectively preserving the structure of the tooth.

    Background: Preoperative nutritional interventions, including low-calorie diets (LCDs) and very low-calorie diets (VLCDs), are commonly implemented in metabolic and bariatric surgery. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of preoperative dietary interventions in patients undergoing bariatric surgery, with primary outcomes including perioperative complications, operative time, and length of hospital stay. Methods: A systematic review and meta-analysis were conducted, including studies that compared LCD and VLCD with regular diets in adults undergoing bariatric surgery. The primary outcomes assessed were perioperative complications, operative time, and length of hospital stay. Random- and fixed effects models were used for quantitative synthesis. Risk of bias was evaluated using the Cochrane Risk of Bias tool and ROBINS-I, while the certainty of evidence was assessed using the GRADE approach. Results: Eight trials comprising 1197 patients were included in the meta-analysis. VLCDs were associated with a significant reduction in perioperative complications (OR 0.59; 95% CI: 0.37–0.94; p = 0.03), whereas LCDs showed no significant effect on complications (OR 1.64; 95% CI: 0.71–3.78; p = 0.25). No significant reduction in operative time was observed (MD −2.64 min; 95% CI: −6.01 to 0.73; p = 0.12). Hospital stay was slightly reduced (MD −0.17 days; p = 0.0001), though the clinical significance remains uncertain. The certainty of evidence was low, primarily due to the risk of bias and small sample sizes. Conclusions: VLCDs may lower the risk of perioperative complications, while LCDs do not appear to provide this benefit. However, the evidence is limited by methodological heterogeneity and low certainty. Further high-quality studies are needed to establish optimal preoperative nutritional protocols.
