Aim: The aim of this study was to assess the effect of different orthodontic treatment needs on the OHQoL of adolescents. Materials and methods: 200 subjects (100 males and 100 females), 11 to 15 years of age were recruited for the study. OHQoL was assessed with the short form of the oral health impact profile (OHIP-14), and malocclusion severity was assessed with the index of orthodontic treatment need (IOTN). The Chi-square test was used to analyse the qualitative data. The level of significance was 0.05. Results: The more severe the malocclusion the worse was the impact on the OHQoL. Orthodontic treatment need had almost similar impact on the daily activities of both males and females. Pronunciation and taste was not significantly affected by the need for orthodontic treatment in either males or females. The proportions of orthodontic patients who found it uncomfortable to eat any food and had to interrupt their meals were significantly correlated with orthodontic treatment needs in both males and females. Conclusion: Orthodontic treatment need had an impact on OHQoL of adolescents with no significant difference between males and females. Clinical significance: Orthodontists should be aware of the impact caused by malocclusion and orthodontic treatment on the quality of life of the patients and should provide regular positive reinforcements to them.

Full length articles such as prospective and retrospective studies, case series, laboratory-based research and reviews form the majority of papers published in the British Journal of Oral and Maxillofacial Surgery (BJOMS). We were interested to evaluate the breakdown of these types of articles both by sub-specialty and the type of study as well as the proportion that are written by UK colleagues compared to overseas authors over a 2 year period (2010-11). A total of 191 full length articles across all sub-specialties of our discipline were published, with 107 papers (56%) coming from UK authors. There were proportionately more oncology papers arising from the UK than overseas (60 and 30% of total respectively) while the opposite was found for cleft/deformity studies (10% and 22%). There was only one laboratory-based study published from the UK compared with 27 papers from overseas. The number of quality papers being submitted to the Journal continues to increase, and the type of article being published between UK and overseas probably reflects different practices and case-loads amongst colleagues. The relatively few UK laboratory based studies published in BJOMS compared to overseas authors are most likely due to authors seeking the most prestigious journals possible for their work. © 2012 The British Association of Oral and Maxillofacial Surgeons.

Oral submucous fibrosis (OSMF) is a complex, debilitating, and precancerous condition. Formerly confined to the Indian subcontinent, it is now often seen in the Asian populations of the United Kingdom, USA, and other developed countries, and is therefore a serious problem for global health. The well-known causative agent of the disease, areca-nut is now recognised as a group one carcinogen. We review and discuss all components of OSMF, including the terminology, presentation, aetiology, and pathogenesis, and provide a brief overview of its management. © 2012 The British Association of Oral and Maxillofacial Surgeons.

Oral submucous fibrosis (OSMF) is known devastating disorder commonly seen in South Asian developing countries. It is directly linked to areca nut chewing and the contents of areca are subjected to multitude of investigations. Among all the contents of areca nut, the copper element has been extensively studied. Most of the published studies have validated its association with OSMF because of its local action. In this paper we postulate a novel biological pathway through which copper is thought to predispose oral mucosa to OSMF. The hypothesis is instructive in explaining various unexplored aspects of the disease. © 2012 Elsevier Ltd. Source

Calretinin is expressed primarily in the central and peripheral nervous system and extensively studied in colon adenocarcinoma and mesotheliomas. Calretinin is known to be expressed in the odontogenic epithelium and odontogenic tumors. However, the role of calretinin in the pathogenesis of odontogenic tumors is yet to be confirmed. Hence, the aim of the present study was to evaluate the expression and role of calretinin in selected odontogenic tumors. The study included 30 ameloblastomas, 30 adenomatoid odontogenic tumors, and 30 keratocystic odontogenic tumors. Staining intensity, pattern, and localization of the immunopositive cells were determined. Statistical analysis was performed using Mann-Whitney U test and Kruskal-Wallis analysis of variance test. P-values <0.05 were considered to be statistically significant. Results showed that 90% ameloblastomas and 80% keratocystic odontogenic tumors were immunopositive to calretinin, whereas none of the adenomatoid odontogenic tumors showed reactivity. Intensity was higher in the ameloblastomas compared with the keratocystic odontogenic tumors. Statistically significant differences were observed when the expression of calretinin was compared, except between the ameloblastoma and keratocystic odontogenic tumor. However, the intensity of calretinin was significantly higher in the ameloblastoma when compared with the keratocystic odontogenic tumor. On the basis of these results, it is suggested that calretinin might be used as a specific immunohistochemical marker for the ameloblastomas and could play an important role in the differentiation of aggressiveness of different odontogenic tumors. Depending on the cell regulatory processes, we suggest a possible role of calretinin in the pathogenesis of ameloblastomas and have to be further studied along with other proliferative cell cycle and apoptotic markers with larger sample size.
