RESUMO
Radicular cyst is one of the most commonly occurring cyst in the oral cavity it is usually preceded by trauma or an infectious condition which is followed by enlargement. In recent times there are several treatment procedures that are being applied in order to improve the postoperative condition and to accelerate the process of healing and regeneration in the affected site. A 22-year-old patient reported to our OPD with the chief complaint of swelling on the left side of the face since 2-3 months, on investigating it was diagnosed as Radicular cyst which was initially treated by endodontic treatment of the involved tooth followed by enucleation of the cyst further an apicoectomy was done. Finally a PRF and iliac crest graft was placed for aesthetic rehabilitation with 21.
RESUMO
The aim was to evaluate and compare the presence of myofibroblasts in oral squamous cell carcinoma (OSCC), verrucous carcinoma (VC), high-risk epithelial dysplasia (HRED), low-risk epithelial dysplasia (LRED), and normal oral mucosa (NOM). The study consisted of 37 OSCC, 15 VC, 15 HRED, 15 LRED and 15 NOM. α-smooth muscle actin (α-SMA) antibody was used to identify myofibroblasts. The α-SMA expression was not observed in NOM and LRED. The α-SMA was expressed in 97.29% of OSCC, 86.66% of VC, 46.66 % of HRED. The α-SMA expression was significantly higher in OSCC than VC (p = 0.023) and HRED (p < 0.000). The α-SMA expression was significantly higher in VC than HRED (p = 0.043). Myofibroblastic expression, as highlighted by α-SMA, is undetectable in NOM and LRED but increases as the disease progresses from potentially malignant disorders, as HRED to VC to invasive OSCC. Thus, proliferation of myofibroblasts may be used as a stromal marker of oral premalignancy and malignancy.
