Diverse clinical nature of cavernous lymphangioma: report of two cases.

Lymphangioma are uncommon hamartomatous congenital malformations of the lymphatic system that involve skin and subcutaneous tissue. They have marked predilection for head and neck region in 75% of cases. Around 50% of lesions are noticed at birth and 90% by 2 years of age. Oral lymphangioma may be present in tongue, palate, buccal mucosa, gingiva and lip. Lymphangioma are of 3 types-simplex, cavernous and cystic lymphangioma. Cavernous lymphangioma is usually seen in fairly dense tissue such as the tongue.We report two unusual cases of cavernous lymphangioma in 24-26 years age group with the site of involvement being floor of the mouth extending into the submandibular triangle in the first case, and the second manifesting as a bluish red swelling on the labial mucosa.

Survey of mesiodens and its characteristics in 2500 children of Davangere city, India.

AIM: The aim of the present study is to report the prevalence of mesiodens and its characteristics and also to present 25 cases with 27 mesiodentes in 2500 children in Davangere city, India. MATERIALS AND METHODS: A survey of 2500 children examined in the Department of Paediatric Dentistry was conducted. Their ages ranged from 3 to 12 years. A total of 27 mesiodentes were diagnosed in 25 patients (1%). The patients' records and radiographs were evaluated and the following variables were studied: age and sex distribution, number, shape, position, eruption status, associated dentition and arch, associated complications and anomalies. RESULTS: In this study were enrolled 16 males and 9 females: 96.2% of the mesiodentes were seen in the maxillary arch while only one in the mandibular arch; 92.5% were observed in the permanent dentition. Most mesiodentes (92.5%) were conical in shape, and about 96.2% were placed vertical in position with only one mesiodens impacted and inverted. Of the 27 mesiodentes, 23 were u%% caused a midline diastema, 14.8% occlusal interference, 7.4% root resorption, and 3.7% had caused delayed eruption of permanent incisors. Rare anomalies like facial talon cusp were found in two mesiodentes (7.4%), and only one (3.7%) had a root anomaly. CONCLUSION: Mesiodens may occur as an isolated finding or can be associated with other odontogenic anomalies.

Efficacy of platelet-rich-plasma (PRP) in bone regeneration after cyst enucleation in pediatric patients--a clinical study.

BACKGROUND: Platelet-rich-plasma (PRP) is a type of natural source of autologous growth factors, and has been used successfully in various fields. However the use ofPRP in children is not well documented. OBJECTIVE: To evaluate the efficacy of adding PRP to a bone graft in the bone regeneration of cystic bony defects following cystectomy. STUDY DESIGN: Study sample included 20 children who were randomly divided into two groups with 10 patients in each group; all underwent cystectomy In the first group (test group), after cystectomy the cystic defect was filled with PRP and bone graft. In the second group (control group) bone graft alone (without PRP) was used. Radiographs were recorded at 1 month, 2 months, 4 months and 6 months intervals after surgery to evaluate the defect bone fill in both groups. RESULTS: The post-operative successive radiographs in the test group showed a significantly greater regeneration of bone in the height of bony defects with application of PRP to bone graft as compared to the control group. In the test group, by the first post operative month, about 58% of the defect was filled, which gradually increased in each month and showed about 94% of defect-fill by 6 months. In the control group, similar observation revealed only 31% of defect-fill by the first post-operative month and a 47% defect-fill at 6 months. CONCLUSION: The addition of PRP to bone graft appeared to enhance bone regeneration considerably. The combination of PRP and bone graft might have a potential for routine clinical use for regeneration of cystic bony defects in children.
