Abstract [en]

Purpose: The aim of this randomized, split-mouth, controlled, clinical study was to evaluate the effect of hyaluronic acid (HA) on patient-related outcome measures (PROM) and wound healing after harvesting of a palatal biopsy.

Material and method: Twenty-five participants were recruited and randomized. A 6x2mm biopsy was harvested from the right and left side at day 0 and 21. Each site was randomly allocated either HA or placebo, which was applied 3 times/day for 7 days. Prior to and directly after the biopsy as well as on day 3, 7, 14, 21, and 42, intraoral scanning and photographs were taken and a questionnaire answered, latter also on day 1 and 2. 

Results: Eighteen participants finished the study. Pain, difficulties eating/drinking, and taste alterations significantly decreased over time and were hardly present after day 7 in both groups without any significant differences between the groups. Color match and volume fill significantly improved over time in both groups. Participants reported significantly more often a positive experience applying HA, the residual wound area on day 7 was significantly smaller in the test/HA group and a tendency was observed for an improved volume fill day 21, after applying HA. 

Conclusion: The results suggest that topically applied 0.3% HA might be beneficial by promoting and accelerating the re-epithelialisation of the wound area and by giving a positive experience after application. However, based on the present results it remains unclear whether this faster healing would potentially result into reduced pain perception in harvesting sites of larger dimensions. 

Abstract [sv]

Syfte: Syftet med denna randomiserade, split-mouth, kontrollerade studien var att utvärdera hyaluronsyras effekt på sårläkning och patientens subjektiva upplevelse efter biopsitagning i gommen.

Material och metod: 25 deltagare rekryterades och randomiserades. En 6x2 mm biopsi togs från höger och vänster sida, dag 0 och 21. Beroende på randomiseringen, tilldelades varje sida antingen HA eller ett placebo. Ämnet applicerades 3 gånger/dag i 7 dagar. Innan och direkt efter biopsin, såväl som dag 3, 7, 14, 21 och 42, togs intraoral scanning och kliniska foton och ett frågeformulär besvarades. Det sistnämnda även dag 1 och 2. 

Resultat: 18 deltagare slutförde studien. Smärta, svårigheter att äta och dricka, och smakförändringar minskade signifikant över tid och var nästan helt försvunna efter dag 7 i båda grupperna, utan någon signifikant skillnad mellan grupperna. Color match och volym utfyllnad ökade signifikant över tid, i båda grupperna. Deltagarna rapporterade signifikant, oftare en positiv upplevelse vid applicering av HA, kvarstående area av såret dag 7 var signifikant mindre i test/HA gruppen och en tendens observerades för en ökad volym utfyllnad dag 21, efter applicering av HA.

Slutsats: Resultaten föreslår att topikalt applicerad 0,3% HA kan vara fördelaktigt genom att främja och accelerera en re-epitelialisering av sårytan area och genom att bidra till en positiv upplevelse efter applicering. Det förblir dock oklart, baserat på studiens resultat, om denna snabbare läkning av sårytan potentiellt kan resultera i en minskad smärta vid större biopsitagning.
