Introduction Three dimensional titanium plating system was developed by Farmand in 1995 to meet the requirements of semi rigid fixation with lesser complication. The purpose of this in vivo prospective study was to evaluate and compare the clinical effectiveness of three dimensional and two dimensional Titanium miniplates for open reduction and fixation of mandibular parasymphysis fracture. Materials and Methods Thirty patients with non-comminuted mandibular parasymphysis fractures were divided randomly into two equal groups and were treated with 2 mm 3D and 2D miniplate system respectively. All patients were systematically monitored at 1st, 2nd, 3rd, 6th week, 3rd and 6th month postoperatively. The outcome parameters recorded were severity of pain, infection, mobility, occlusion derangement, paresthesia and implant failure. The data so collected was analyzed using independent t test and Chi square test (a = .05).Results The results showed that one patient in each group had post-operative infection, occlusion derangement and mobility (p [ .05). In Group A, one patient had paresthesia while in Group B, two patients had paresthesia (p [ .05). None of the patients in both the groups had implant failure. There was no statistically significant difference between 3D and 2D miniplate system in all the recorded parameters at all the follow-ups (p [ .05).Conclusion 3D miniplates were found to be better than 2D miniplates in terms of cost, ease of surgery and operative time. However, 3D miniplates were unfavorable for cases where fracture line was oblique and in close proximity to mental foramen, where they were difficult to adapt and more chances for tooth-root damage and inadvertent injury to the mental nerve due to traction.Keywords Three dimensional titanium miniplate (3D) Á Two dimensional titanium miniplate (2D) Á Mandibular parasymphysis fracture Á Open reduction and internal fixation

Background Dirofilariasis is an endemic disease in tropical and subtropical countries caused by about 40 different species of dirofilari. Dirofilariasis of the oral cavity is extremely rare and is usually seen as mucosal or submucosal nodules. We also present a case of dirofilariasis of the mandibular third molar region submucosally in a 26 year old male patient. Purpose To identify, enlist and analyze the cases of dirofilariasis in maxillofacial region reported worldwide so as to understand the clinical presentation and encourage the consideration of helminthic infections as a possible differential diagnosis in maxillofacial swellings. Methods Two authors KC and SK independently searched the electronic database of PUBMED, OVID, Google Scholar and manual search from other sources. A general search strategy was planned and anatomic areas of interest identified. The search was made within a bracket of 1 month by the independent authors KC and SK who assessed titles, abstracts and full texts of articles based on the decided keywords. The final selection of articles was screened for the cases that were reported in the maxillofacial region including the age, gender, site of occurrence and region of the world reported in. A geographic distribution of the reported cases was tabulated. Results A total number of 265, 97, 1327, 3 articles were identified by PubMed, Ovid, GoogleScholar and manual search respectively. The final articles were manually searched for duplicates and filtered according to the inclusion/exclusion criteria which led to a final list of 58 unique articles that were included in the study. In total 99 cases were identified. Conclusion Although intraoral dirofilarial infections are extremely uncommon, it should be considered in the differential diagnosis of an intraoral or facial swelling that does not completely respond to routine therapy especially in patients from endemic areas.
