Emergency Preparedness for Local Anesthetic Systemic Toxicity in Dental Practice: Dentists' Knowledge, Awareness, and Institutional Availability of Lipid Emulsion Therapy.
Article in Healthcare (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThis study aimed to evaluate the knowledge and clinical awareness of local anesthetic systemic toxicity (LAST), preventive practices, knowledge of lipid emulsion therapy, and institutional availability among dentists actively practicing in Türkiye, and to examine the demographic and professional factors associated with knowledge level.
methodsThis descriptive cross-sectional study was conducted using a 15-item online questionnaire developed by the researchers. The analyses included 369 dentists actively practicing in Türkiye. Data were analyzed using descriptive statistics, the Kruskal-Wallis test, Dunn-Bonferroni pairwise comparisons, Spearman rank correlation, and multinomial logistic regression analysis.
resultsAmong the participants, 45.8% reported having basic knowledge of LAST, whereas only 2.7% reported detailed knowledge, including the management steps. Although 40.1% stated that they calculated the local anesthetic dose according to the patient's body weight, only 3.3% reported preparing an emergency response plan for LAST, and 2.2% indicated that they were prepared to use treatment options such as lipid emulsion. Regarding lipid emulsion therapy, 59.1% of participants had low knowledge and 24.4% had superficial knowledge; only 0.5% reported detailed knowledge of the administration steps and dosing protocol. In terms of institutional availability, 45.0% did not know whether lipid emulsion was available at their institution, 40.9% reported that it was unavailable, and 14.1% reported that it was available. Knowledge levels differed according to professional status; however, the effect size was small (H(2) = 13.129;
conclusionsAlthough dentists' self-reported awareness of LAST varied, detailed knowledge of the administration steps and dosing protocol for lipid emulsion therapy, as well as institutional preparedness, remained limited. The findings suggest that strengthening practice-oriented education on the prevention and management of LAST and reviewing lipid emulsion availability and emergency response protocols in clinical institutions may be beneficial.
