Background & Objective : Many complications are associated with the surgical removal of impacted third molars.

One of these complications is the formation of a deep periodontal pocket distal to the second mandibular molar .

Plasma Rich in Growth Factors is a material containing many growth factors Which have an essential role in wounds healing and tissue regeneration.

The aim of this study was to assess the efficacy of autologous PRGF in bone regeneration techniques to prevent development of periodontal pocket at the distal root of the mandibular second molar following extraction of an impacted third molar Materials & Methods: 15 systemically healthy patients (9 males and 6 females, aged 19 to 25, median age of 22.4 years) with bilateral fully impacted mandibular molars participated in the study .

The third molar was extracted, the test defects were implanted with PRGF prepared according to Anitua et al (experimental), and the other sites served as unimplanted (control).

Plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and gingival recession (GR) were recorded prior to surgery, and at 3, and 6 months postsurgery.

Digital panoramic radiographs were taken after a week, and 6 months postsurgically to evaluate the changes in Alveolar bone height .

Results : Both treatment procedures led to probing depth increase ( PRGF 0.7 ± 0.81 mm, control 1.1 ± 0.78 mm), clinical attachment lose ( PRGF 1.2 ± 1mm, control 3.3 ± 1.11 mm), and gingival recession ( PRGF 0.5 ± 0.8 mm, control 2.2 ± 0.9 mm).

Radiographic evaluation revealed of increased of Alveolar bone height ( PRGF 1.1 ± 0.5 mm, control 0.6 ± 0.4 mm) .

The changes in PD and ABH were not statistically significant wherease The changes in CAL and GR were statistically significant in control groub (P=0.05).

Conclusion: This study indicates that Plasma Rich in Growth Factors is effective in the treatment of periodontal defects at the distal root of the mandibular second molar after surgical extraction of impacted mandibular third molar
