Eruption cyst 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. Intraoral examination of four patients revealed eruption cyst. Among these, in three patients it occurred in the maxillary arch and one had it in the mandibular arch. All were associated with permanent tooth. Surgical treatment was done in three cases and in one case the cyst disappeared gradually and tooth erupted in normal pattern. Four cases of eruption cyst from India are presented and literature on this condition is reviewed. 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.
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 of PRP 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.
Oligodontia (severe partial anodontia) is a rare developmental dental anomaly refers to congenital lack of more than six teeth. Most often oligodontia appears as part of some congenital syndromes that affects several organ systems. The exact etiology for oligodontia is unknown. Management includes various restorative and orthodontic procedures to improve the esthetics and function. The present article reports a case of oligodontia of 14 number of permanent teeth excluding third molars in a non-syndromic female patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
