Effect of Surface Anesthetics on Tongue Sensory Function.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLidocaine hydrochloride (LDCA) is one of the medications used to treat burning mouth syndrome (BMS). The purpose of this study is to investigate whether benzocaine (BEN) can also be used for the treatment and examination of BMS. This study used quantitative sensory testing to investigate the effects of two surface anesthetics on the sensory function of the tongue tip.
methodsThirty healthy women participated in this study. All participants completed a single-blind, randomized crossover study. Surface anesthetics- (2%LDCA, 20%BEN) and vaseline (control) were applied to the tongue tip. The experiment was conducted over three days, with each drug applied on a different day in a randomized order. The mechanical detection threshold (MDT), mechanical pain threshold (MPT), and numerical rating scale (NRS) were measured at the following points: before application of the drug (pre), immediately, at 5, 15, 30, and 60 minutes after application of the drug.
resultsMDT immediately (P < 0.01), at 5 (P < 0.01) and 15 (2%LDCA: P = 0.0112, 20%BEN: P = 0.0128) minutes after application of the drug were significantly higher than pre-values in both local anesthetic sessions. MPT immediately (P < 0.01), at 5 (P < 0.01), 15 (P < 0.01), and 30 (P = 0.0026) minutes after application of 2%LDCA was significantly higher than pre-values. MPT immediately (P < 0.01), at 5 (P < 0.01) and 15 (P = 0.0057) minutes after application of 20%BEN was significantly higher than pre-values. NRS scores did not differ significantly between measurement periods or between drugs.
conclusionsThis study suggested that 2%LDCA and 20%BEN may have comparable anesthetic effects on the sensory function of the healthy tongue tip.
