ABSTRACT
Radicular cyst is the most common inflammatory odontogenic cystic lesion of the jaws. It usually originates as sequel to a periapical inflammatory process, following chemical, physical or bacterial injury. Due to its chronic etiology, the cyst usually appears in the later stages of life. It has a male sex predilection, with the maxillary anterior region as the most common site of involvement. This article describes an unusual case of a large radicular cyst in the posterior maxilla along with its management and follow-up.
ABSTRACT
The eruption cyst is regarded as a soft tissue analogue of the dentigerous cyst, but is considered as a distinct clinical entity. It is defined as a cyst that lies superficial to the crown of an erupting tooth, and is lined by stratified squamous non-keratinizing epithelium. Clinically, it appears as a soft, often translucent swelling of the gingival mucosa overlying the crown of the involved tooth, and may vary from pink to bluish-purple in colour. It is usually seen in children and the teeth commonly affected include the permanent first molars and maxillary incisors. Radiographically, no evidence of bone involvement is seen and treatment consists of simple excision of the roof of the cyst. This paper describes a case of an eruption cyst in a 7-year old male patient, which presented as a swelling involving the gingiva overlying the crown of 21, along with a review of the literature.
ABSTRACT
odontogenic keratocyst are unique odontogenic lesion that have a potential to behave aggressively and which can reccur . It usually occurs in mandibular ramus region which is the third most common site for odontogenic cysts. OKC may occur at any age mostly in 2nd and 3 rd decades of life with male predilection, with presenting features as pain and swelling , a case of 42 years male presented with pain and swelling and clear radiological evidence of OKC and confirmed by histo pathological proof.
ABSTRACT
An unusual case of impacted and inverted maxillary central incisor is reported in a 12 year old girl. The inverted maxillary central incisor was not associated with any other anomaly which is rare.

The effects of exposing seawater adapted cichlid fish, tilapia (Sarotherodon mossambicus Peters) to sublethal concentrations of toluene on the activities of lactate dehydrogenase, succinate dehydrogenase and acetylcholinesterase were studied. The activity of lactate dehydrogenase increased while those of succinate dehydrogenase and acetylcholinesterase were inhibited in most tissues of the exposed fish. The alterations in the dehydrogenases suggested that some changes in carbohydrate metabolism may have occurred. Acetylcholinesterase inhibition in brain and other tissues indicated impairment of nervous function in toluene-intoxicated tilapia.
