Evaluation of the Tunnelling Technique for Upper Labial Frenectomy Using ER:YAG Laser.
Review in Journal of clinical and experimental dentistry, 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
Background: An abnormal upper labial frenum (ULF) can represent a potentially harmful gingival insertion located between the central incisors. Lasers, particularly the Er:YAG laser, have been described for ULF frenectomy and offer several promising advantages. The aim of this study was to evaluate the usefulness of Er:YAG laser frenectomy using the "tunnelization technique" for the elimination of an abnormal upper labial frenum. Material and Methods: This cohort study evaluated ULF frenectomy using the tunnelling technique with an Er:YAG laser in a cohort of 20 patients treated between January 2011 and December 2024. The ULFs were morphologically and clinically characterized before and after the procedure. Results: No intraoperative complications were observed during the frenectomy, apart from moderate intraoperative bleeding in 12 patients (60%), with no sutures required in any case. Postoperatively, analgesic medication was required by only 2 patients (10%) for mild pain. At the 3-month follow-up, a significant reduction was observed in both frenulum size (P<0.001) and interincisal diastema (P=0.008). All incisive papillae were preserved without any defects. Conclusions: Er:YAG laser frenectomy using the tunneling technique proved to be a suitable option, resulting in the immediate preservation of the incisive papilla and a reduction in ULF size and position, without significant associated complications.
