5-fluorouracil (5-FU) is a pyrimidine analog which can work as antineoplastic antimetabolite by blocking thymidylate synthetase conversion of deoxyuridylic acid to thymidylic acid in DNA synthesis. This study is aimed to know the anticancer effect of 5-FU on the expressions of important signaling proteins in KB cells through immunoprecipitation high performance liquid chromatography (IP-HPLC). KB cells were treated with 5 μM 5-FU and cultured for 12, 24, 48, 72, and 96 hours, and followed by IP-HPLC analysis using 32 antisera. 5-FU suppressed the proliferation of KB cells by decreases in the expressions of proliferation-related proteins, Ki-67, PCNA, CDK4, and MPM2 to 82.6%, 92.4%, 95.2%, and 95.9%, respectively, but increases of antiproliferation-related proteins, p16 and p21 to 106.7% and 125.5%, respectively, during 96 hours of experiment. This proliferation reduction was also negatively regulated by cMyc/MAX/MAD network signaling. The cellular protection and survival were consistently arrested by 5-FU treatment in KB cells. The expressions of NFkB, MDR, p-mTOR, and TNFα were decreased to 95.1%, 92.8%, 93.4%, and 90.3% in 48-72 hours, respectively, while cellular stress was increased by upregulation of p38 to 111.3% in 48 hours. And the expressions of pAKT1/2/3, hTERT, and AMPK were also decreased to 93.3%, 97.4%, and 89.3% in 24-48 hours, respectively, while the cellular transformation might be undergone by upregulation of TGF-β1 to 117% until 96 hours. Particularly, 5-FU treatment greatly induced the cellular apoptosis in KB cells by increased expressions of PARP, cPARP, caspase 9, c-caspase 9, caspase 8, and caspase 3 in the lack of p53/BAX and FASL/FAS signaling. The expressions of PARP and c-PARP were increased maximum to 119.2% in 24 hours, and followed by increases of caspase 9, c-caspase 9, caspase 8, and caspase 3 to 111.2%, 125.9%, 108.6%, and 116.3% in 72-96 hours. Therefore, it is presumed that 5-FU induced cellular apoptosis in KB cells may be derived from the overexpression of PARP due to the increased DNA defect caused by 5-FU, which can lead to ATP depletion and subsequent cellular apoptosis.

Tooth autotransplantation is the placement of an impacted or erupted tooth into an extraction site or surgically prepared dental socket within the same individual. This procedure may become a new treatment alternative, because of its osteogenetic potential and its ability to promote regeneration of alveolar processes. The present study reports the case of a 10-year-old girl whose maxillary central incisor was ankylosed as the result of an injury, and who underwent tooth autotransplantation and orthodontic treatment for the functional and aesthetic recovery of the maxillary central incisor. The transplanted tooth showed satisfactory alveolar bone recovery, and orthodontic tooth movement. No complications occurred. We chose to report this case because it illustrates the autotransplantation of a premolar in a child scheduled for orthodontic treatment, including tooth extraction. The procedure showed good prognosis in terms of the recovery of an anterior tooth affected by an injury.

Kaposi’s sarcoma is one of the first recognized in HIV infection even patient can develop KS in any disease stage. Moreover, the oral cavity may be the first site of Kaposi’s sarcoma and oral mucosa involvements of KS in HIV positive are very critical because it had a higher death rate than those who having exclusively cutaneous manifestations of the disease. Early detection of KS oral involvement is very important to prevent disease burden. This case is about a 48 years old male who was first discovered Oral Kaposi’s Sarcoma as HIV infection sign. He didn’t notice any other discomfort other than oral mucosa swelling.

Acinic cell carcinoma is a well-differentiated, low-grade tumor that accounts for 1-3% of salivary gland tumors. Among the variant of acinic cell carcinoma, papillary cystic variant of acinic cell carcinoma is much more rare and it is known to be difficult to diagnose and has a poor prognosis. In this paper, we report a case of 58 - year - old man diagnosed as papillary cystic variant of acinic cell carcinoma and the characteristics of the lesion by integrating the recent cases of papillary cystic variant of acinic cell carcinoma. This study emphasizes the need for long-term studies and further investigation of papillary cystic variants of acinic cell carcinoma.

The dentigerous cyst is defined as a cyst that originates by the separation of the follicle from around the crown of an unerupted tooth. This is the most common type of developmental odontogenic cyst, making up about 20% of all epithelium-lined cysts of the jaws. Large dentigerous cysts are uncommon, but some cases are large cysts. The usual treatment for a dentigerous cyst is careful enucleation of the cyst together with removal of the unerupted tooth. Large dentigerous cysts also may be treated by decompression. This permits decompression of the cyst, with a resulting reduction in the size of the bone defect. The cyst can then be enucleated at a later date with a less extensive surgical procedure and important structures such as teeth and the inferior alveolar nerve can be preserved. These cases are large dentigerous cysts treated by decompression. Less extensive surgical procedures were used and some teeth were preserved.

White sponge nevus (WSN) is a rare autosomal dominant disorder characterised by rough thickening, fissure formation, and a whitish colour change in the oral mucosa. This disorder predominantly affects the nonkeratinized stratified squamous epithelium of the mucosa. We experienced a familial case of WSN (i.e., a mother and her two daughters) and performed keratin gene analysis and immunohistochemical staining. The results of a mutation analysis revealed the presence of a heterozygous missense mutation 344T to G in KRT13, predicting an amino acid change leucine (L) to arginine (R), in the 1A domain of the KRT13 polypeptide. Immunohistochemically, the loss of keratin 4 expression was found.
