Lichen planus (LP) is a chronic mucocutaneous disorder in which auto-cytotoxic T lymphocytes trigger apoptosis of epithelial cells leading to chronic inflammation. Oral Lichen Planus (OLP) is a disease which has a slight malignant potency. The diagnosis of OLP can be made from the clinical features if they are sufficiently characterized, but biopsy is recommended to confirm the diagnosis and to exclude dysplasia and malignancy. This is a case report of erosive lichen planus in a female patient, aged 45 years.

Behçet’s syndrome is a chronic multisystem vasculitis characterized by mucocutaneous, articular, neurological, gastrointestinal and ophthalmological lesions. Behcet’s syndrome is a disease of uncertain etiology. It may be due to immune dysregulation including circulating immune complex, autoimmune cytokines and heat shock proteins are major factor in the pathogenesis of Behcet’s syndrome. Patient’s positive pathergy test suggests a diagnosis of Behcet’s disease. Corticosteroids and immunosupressive drugs are the first line of treatment. This is a case report of juvenile Behcet’s syndrome in a thirteen year old girl associated with arthritis.

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.

Actinic lichen planus is a rare variant of lichen planus seen commonly in tropical and subtropical countries in the dark complexioned individuals. It manifests in the sun exposed areas of the face, neck and limbs. Though many cases have been reported in the skin, few lesions associated with the lip have been reported. The Lip is highly susceptible to actinic changes increasing the chances of malignancies. This is an unusual case report of 32 year old female patient where the lip lesion was seen mimicking discoid lupus erythematoses.

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.
