Background: Chlorhexidine digluconate (CHX) is considered a gold standard in the antiseptic treatment of oral mucosae. However, recent studies have shown that its use in the oral cavity can lead to scar healing, alteration of the oral microbiome, and reduced cellular proliferation due to toxic effects on fibroblasts. As a result, various biopharmaceutical products have been adopted over the years. In particular, tocopherol appears to accelerate cellular proliferation in wound healing processes and have fewer side effects than chlorhexidine. Aim: this randomized clinical trial evaluated the efficacy of topical tocopherol acetate compared to 0.2% chlorhexidine in easing oral discomfort in patients undergoing oral biopsy. Materials and Methods: A total of 77 patients undergoing oral biopsy were randomly assigned to two groups: the test group (TG) received tocopherol acetate treatment, and the control group (CG) received 0.2% chlorhexidine treatment. The primary outcome was pain reduction (VAS-D) on the first and sixth postoperative days. The secondary outcome was to evaluate the quality of healing by measuring the height and width of the postoperative site from analyzed and standardized photographs using ImageJ. The use of painkillers was recorded. The CONSORT guidelines were used for the study design. The trial was approved by the Ethics Committee for Clinical Trials (CESC) of the province of Padua (n. 005516) and was registered on the ISRCTN Registry (n. 11647292). Results: No statistically significant differences were found between the two treatments in terms of VAS scores (p>0.05; 0.99), height and width of the postoperative site (p=0.91; p=0.71), or between patients who took painkillers and those who did not (p=0.83; p=0.92). Significant differences were observed for VAS scores within each group (p(TG)<0.0001; p(CG)<0.0001) Conclusions: The use of tocopherol on the postoperative site of the biopsy sample should be considered instead of chlorhexidine.
Introduzione: la clorexidina digluconato (CHX) è considerata un gold standard nel trattamento antisettico delle mucose orali. Studi recenti hanno dimostrato come l’utilizzo di clorexidina in cavo induca una guarigione tissutale con esito cicatriziale, una alterazione del microbioma orale oltre a riduzione della proliferazione cellulare avendo effetti tossici sui fibroblasti. Per tale motivo, negli anni sono stati adottati prodotti biofarmaceutici vari, in particolare, il tocoferolo sembra accelerare la proliferazione cellulare nei processi di guarigione tissutale e avere meno effetti collaterali della clorexidina. Scopo dello studio: questo studio clinico randomizzato ha valutato l'efficacia del tocoferolo acetato topico rispetto alla clorexidina 0.2% nell'alleviare il dolore nei pazienti sottoposti a biopsia del cavo orale. Materiali e metodi: un totale di settantasette pazienti candidati a biopsia del cavo orale sono stati assegnati in modo randomizzato a due gruppi: il gruppo test (TG) ha ricevuto il trattamento a base di tocoferolo acetato, il gruppo controllo (CG) il trattamento a base di clorexidina 0.2%. L’outcome primario era la riduzione del dolore (VAS-D) al primo e al sesto giorno post-operatorio. L’outcome secondario era valutare la qualità della guarigione mediante la misurazione dell'altezza e della larghezza del sito post-operatorio da fotografie analizzate e standardizzate con ImageJ. È stato registrato l'utilizzo di antidolorifici. Per il disegno dello studio sono state utilizzate le linee guida CONSORT. Il trial ha ottenuto l’approvazione del Comitato Etico per la Sperimentazione Clinica (CESC) della provincia di Padova (n. 005516); è stato registrato su ISRCTN Registry (n. 11647292). Risultati: non sono emerse differenze statisticamente significative tra i due trattamenti in termini di punteggi VAS (p>0.05; 0.99), né di altezza e larghezza del sito post-operatorio (p=0.91; p=0.71), né tra i pazienti che hanno assunto antidolorifici né in quelli che non lo hanno fatto (p=0.83; p=0.92). Sono state osservate differenze significative per i punteggi VAS in ciascun gruppo (p(TG)<0.0001; p(CG)<0.0001). Conclusioni: l'uso di tocoferolo sul sito post-operatorio del campione bioptico dovrebbe essere preso in considerazione al posto della clorexidina.
