Association between blood groups and odontogenic lesions: a preliminary report

Abstract

Introduction: Blood type is a genetic characteristic that is related to some diseases and deformities. The di verse characteristics of pathological lesions complicate the prediction of genetic pattern of a specific cyst or tumor. Nevertheless, epidemiological evaluations can reveal relationships between some lesions or accompanying dis eases as well as some genetic characteristics of the patient. These associations will help to guide the identification and treatment of lesions. Objectives: This study aimed to evaluate the relationship between blood groups and the incidence of odonto genic cysts and tumors. Material and methods: Simple random sampling was performed in this retrospective study. A total of 129 cases that were histopathologically diagnosed with a radicular cyst, odontogenic keratocyst, dentigerous cyst, or ameloblastoma, between 2005 and 2016 with complete data were evaluated. Results: Among 129 cases, 76 (58.9%) and 53 (41.1%) cases were male and female, respectively. Among all cases, 51 (39.5%), 38 (29.4%), 22 (17.1%), and 18 (14%) had O, A, B, or AB blood types, respectively. Among these cases, 47 (36.4%), 39 (30.2%), 22 (17.1%), and 21 (16.3) had a dentigerous cyst, odontogenic keratocyst, radicular cyst, or ameloblastoma, respectively. Conclusions: Blood groups "B" and "AB" are associated with a high incidence of odontogenic lesions and dentige rous cysts.

The effects of Kinesio tapes on facial swelling following bimaxillary orthognathic surgery in the supraclavicular region

“…Despite its increasing use in rehabilitation and injury prevention protocols, there is no clear evidence of the mechanisms behind the beneficial effects of KT. Several promising studies and reports have been presented, but more evidence-based studies are needed to prove clinically beneficial effects [ 19 ]. On the whole, however, KT has been shown to have the potential to reduce swelling and hematoma [ 15 ].…”

Effect of inter-dental abutment distance on the impression accuracy of digital and conventional methods

“…CAD-CAM technology can produce a virtual 3D model with digital intraoral scanners [18,19]. Digital impressions have many advantages, including rapid casting, storing information indefinitely, 3D pre-visualization of tooth preparation, and transfer of digital scans between the dental office and the laboratory [20][21][22][23][24]. This method reduces many common errors related to JOURNAL of MEDICINE and LIFE the conventional method, including dimensional variations of impression materials, dental stone expansion, and human errors [25,26].…”
