Epulis fissuratum is a benign tumor like inflammatory hyperplastic growth which occurs on the mucosa along the borders of an ill fitting full or partial removable denture. If ulcerated, it can mimic oral squamous cell carcinoma. The treatment includes surgical removal of excess fibrous tissue and remodelling or reconstructing the denture suitably, ensuring better adaptability to the ridges. This case report describes a 55 year old male patient with characteristic clinical features of denture induced inflammatory hyperplasia.

Fibromas are the benign tumours that are most commonly encountered among the oral soft tissue lesions. They are mostly seen as a protective mechanism of the mucosa towards chronic irritation. They present clinically as a round or ovoid, soft to firm in consistency, exophytic growth, mostly pale pink in colour with smooth surface. These lesions are asymptomatic and do not require any treatment until bothersome to the patient. The clinical features, histopathological features and treatment of an irritational fibroma occurring on the hard palate of a 32 year old female are presented.

Eruption cyst (EC) is a benign cyst associated with a primary or permanent tooth in its soft tissue phase after erupting through the bone. It is most prevalent in the Caucasian race. It is clinically significant in that knowledge among general dentists is very essential regarding this developmental disturbance to reach the correct diagnosis and to provide proper treatment. We are reporting a case of eruption cyst in an 11 year old boy.

Dermoid cysts are rare developmental benign lesions that arise as a result of ectodermal differentiation of multipotent cells. Histologically the cysts are classified as dermoid, epidermoid and teratoid cysts depending on the presence of adnexal structures and derivatives of germ layers. When dermoid cysts appear in the floor of the mouth they can cause difficulty in deglutition and respiration. The differential diagnosis of dermoid cyst could be infection, ranulaor tumor. Intraoral or extra oral approach for enucleation is the method of treatment. Dermoid cysts have a good prognosis with low malignancy and recurrence rate. A case report of a dermoid cyst in the floor of the mouth is presented in this paper along with clinical, histopathological evaluation and the treatment.

Cutaneous sins tract of dental origin are often misdiagnosed and inappropriately treated because of their uncommon occurrence and absence of symptoms in about half of the patients. A case report describing the diagnosis and treatment of an extra oral cutaneous sinus tract of odontogenic origin in relation to mandibular left first molar with surgical treatment and proper antibiotic coverage is presented.

The mucocele is a salivary gland pathology that results from rupture of salivary gland duct and spillage of mucin into the surrounding tissues. The term mucous extravacation is also used to describe this lesion. The rupture of the gland or duct may be due to local trauma. The most common site of mucocele is lower lip. The treatment of mucocele includes cryosurgery , intra-lesional corticosteroid injection, micro-marsupialization, marsupialization of the mucocele, conventional surgical removal of the lesion , and laser ablation. The advantages of laser ablation over other methods include less treatment time, avoidance of suturing, minimal complications and relapse. Here we report a case of mucocele on lower lip treated using diode laser.

Dentinogenesis imperfecta is an autosomal dominant disorder of tooth development characterized by the presence of opalescent dentine, resulting in a dusky blue to brownish discoloration of the teeth. It is the most common dental genetic disease. This condition is genetically and clinically heterogeneous, it may affect only the teeth or it may be associated with the osteogenesis imperfecta. Diagnosis is based on history, clinical examination and radiographic features. This report describes an 18 year old male patient who showed the characteristic dental features of dentinogenesis imperfecta.

ABSTRACT The use of tooth-derived material as a scaffold has gained attention recently due to its ease of availability and bioactive properties. Hence, the objective of this study was to determine in vitro interaction of human gingival mesenchymal stem cells (hGMSCs) with human demineralised teeth matrix (hDTM) on osteogenic potential with or without osteogenic inducers. The hGMSCs were established and characterised on their morphology, proliferation, population doubling time (PDT), viability, colony-forming ability, expression of cell surface markers and adipogenic differentiation. Further, the effect of hDTM on the biocompatibility and osteogenic differentiation ability of hGMSCs was evaluated. The hGMSCs displayed a fibroblast-like appearance and exhibited a greater proliferative activity. The cells showed > 91% viability, and PDT varied between 39.34 hours and 62.59 hours. Further, hGMSCs indicated their propensity to form clusters/ colonies, and expressed the markers, such as CD29, CD44, CD73 and CD90, but were negative for CD34 and CD45. When treated with adipogenic induction medium, hGMSCs were able to exhibit the formation of neutral lipid vacuoles. The hGMSCs cultured with hDTM did not show any cytotoxic changes including morphology and viability. Mineralisation of calcium nodules was observed in hGMSCs when cultured in osteogenic induction (OI) medium as an indication of osteogenesis. hGMSCs when cultured with hDTM confirmed the presence of a mineralised matrix. Further, when the cells were cultured with hDTM along with OI, they showed slightly enhanced differentiation into osteocytes. In conclusion, hGMSCs were shown to be biocompatible with hDTM, and demonstrated their enhanced osteogenic potential in the presence of hDTM and osteogenic supplements.
