PRF membrane as good as SCTG technique for treating papillary recession defects: Study

The authors investigated a total of 20 sites with Class I and Class II interdental papilla defects. These sites were assigned into two groups: Group 1 – Han and Takie technique + SCTG; Group 2: Han and Takie technique + PRF. Parameters such as papillary height (PH), distance from the contact point to the tip of papillae (CPTP), papilla presence index (PPI), pocket probing depth (PPD), relative clinical attachment level (RCAL), plaque index (PI), gingival index (GI), and distance from contact point to an alveolar crest (CP‑BC) was measured at baseline and after 3 months.

The authors observed the following results-

2. The mean PI, GI, PPD, RCAL, PPI, and CPTP distance decreased significantly, whereas the mean PH increased significantly in Group 1 as well as in Group 2.
3. After 3 months, mean reduction in CPTP distance and mean gain in PH were statistically significant in Group 1 as compared to Group 2.
4. However, there was no significant difference in mean CPBC distance between baseline and 3 months in Group 1 as well as in Group 2.

Hence, the researchers concluded that "both Han and Takie technique with SCTG and Han and Takie technique with PRF was effective in the surgical reconstruction of interdental papillary recession defects. Although the SCTG technique provided a better result in terms of interdental papilla fill, PRF avoids the second donor site, thus decreasing the patient's morbidity. Therefore, PRF could be considered an alternative to the "gold standard" SCTG. The effect needs to be further investigated using long-term clinical and histological studies."
