Gingival SCC is the malignancy of gingival epithelium. Prevalence of gingival and alveolar process SCC is 2% to 12% of diagnosed cases. However, it occurs much more frequently in the mandible than in the maxilla. The purpose of this case report is to introduce a case of gingival SCC in the anterior maxilla with no diagnosed risk factor.

A 49-year- old male with the chief complaint of a growing mass in anterior maxillary gingiva with the differential diagnosis of reactive lesions for three months. Panoramic and periapical examination showed no evidence of generalized alveolar bone resorption. After the excisional biopsy, in the follow-up session, the recurrence of the lesion was seen. Considering rapidly growth of the lesion, suspension to SCC was reinforced and the next excisional biopsy was done. Histopathologic analysis established the diagnosis of squamous cell carcinoma.

SCC is a great imitator; for lesions with a benign appearance on the gingiva and it should be considered in the differential diagnosis. This case report revealed the importance of early diagnosis of gingival SCC. Considering the low survival rate of gingival SCC and its high morbidity, early diagnosis help improves the survival of the patient

The aim of the present study was to evaluate the biocompatibility of two modified formulations of Portland cement (PC) mixed with either titanium oxide or both titanium oxide and calcium chloride.
Methods and Materials: Polyethylene tubes were filled with modified PCs or Angelus MTA as the control; the tubes were then implanted in 28 Wistar rats subcutaneously. One tube was left empty as a negative control in each rat. Histologic samples were taken after 7, 15, 30 and 60 days. Sections were assessed histologically for inflammatory responses and presence of fibrous capsule and granulation tissue formation. Data were analyzed using the Fisher’s exact and Kruskal-Wallis tests.
PC mixed with titanium oxide showed the highest mean scores of inflammation compared with others. There was no statistically significant difference in the mean inflammatory grades between all groups in each of the understudy time intervals.
The results showed favorable biocompatibility of these modified PC mixed with calcium chloride and titanium oxide.
