Leukoplakias are oral white lesions that have not been diagnosed as any other specific disease. They are grouped under premalignant lesions, now redesignated as potentially malignant disorders. Their significance lies in the fact that they have propensity for malignant transformation at a higher rate when compared to other oral lesions. This article reviews aetiology, epidemiology, clinical characteristics, histopathologic features, malignant potential and treatment of oral leukoplakia.

Cemento-ossifying fibroma is a fibro-osseous lesion which belongs to the same category as fibrous dysplasia and cement-ossifying dysplasia. In a recent WHO classification (2005), the term 'cemento-ossifying fibroma' was replaced with 'ossifying fibroma'. These are slow growing, painless lesions which are seen more commonly in women between the third and fourth decades of life. We are reporting an unusual case report of a central ossifying fibroma of the left mandible in an 18 year old male patient who presented with a painful swelling on the left side of the face. The lesion was treated with surgical resection and reconstruction.

The Papillon Lefevre syndrome is an autosomal recessive disorder which is characterized by various dermatological manifestations and periodontitis as a manifestation of a systemic disease. Its aetiopathogenesis is thought to be secondary to the mutation of the Cathepsin C gene. Various studies have shown that the immune related cells like the polymorphonuclear leucocytes and the macrophages and their precursors were affected. This report elicits about an edentulous male with this syndrome, who was treated with a modified complete denture prosthesis (hollow, maxillary, complete denture), considering his young age and low socioeconomic status.

With the increased interest in adult orthodontics, maxillary width problems in the nongrowing individuals have been encountered with greater frequency. In view of the negative outlook for successful nonsurgical palatal expansion in adult patients it seems appropriate to evaluate the biomechanical effects of nonsurgical rapid maxillary expansion (RME) in adults using the finite element method. The analytical model in this study was developed from a dry human skull of an adult female with an approximate age of 20 years. Known transversal (X) displacement were applied on the maxillary canine and first permanent molar crown. The displacements and Von-Mises stresses in different planes were studied on different nodes located at various structures of the craniofacial complex. Transverse orthopedic forces not only produced an expansive force at the intermaxillary suture but also high forces on various structures of the craniofacial complex, particularly at the base of the sphenoid bone and frontal process of the zygomatic bone. Lateral bending of the free ends of the pterygoid plates were noted, with increased resistance demonstrated in superior parts attached to the cranial base. Rapid maxillary expansion must be used judiciously in adults, because of its far-reaching effects.

Introduction: The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Vinyl Polysiloxane Impression materials (VPS) are most frequently used as the impression material in fixed prosthodontics. As VPS is hydrophobic when it is poured with gypsum products, manufacturers added intrinsic surfactants and marketed as hydrophilic VPS. These hydrophilic VPS have shown increased wettability with gypsum slurries. VPS are available in different viscosities ranging from very low to very high for usage under different impression techniques. Aim: To compare the dimensional accuracy of hydrophilic VPS and hydrophobic VPS using monophase, one step and two step putty wash impression techniques. Materials and Methods: To test the dimensional accuracy of the impression materials a stainless steel die was fabricated as prescribed by ADA specification no. 19 for elastomeric impression materials. A total. of 60 impressions were made. The materials were divided into two groups, Group1 hydrophilic VPS (Aquasil) and Group 2 hydrophobic VPS (Variotime). These were further divided into three subgroups A, B, C for monophase, one-step and two-step putty wash technique with 10 samples in each subgroup. The dimensional accuracy of the impressions was evaluated after 24 hours using vertical profile projector with lens magnification range of 20X-125X illumination. The study was analyzed through one-way ANOVA, post-hoc Tukey HSD test and unpaired t-test for mean comparison between groups. Results: Results showed that the three different impression techniques (monophase, 1-step, 2-step putty wash techniques) did cause significant change in dimensional accuracy between hydrophilic VPS and hydrophobic VPS impression materials. One-way ANOVA disclosed, mean dimensional change and SD for hydrophilic VPS varied between 0.56% and 0.16%, which were low, suggesting hydrophilic VPS was satisfactory with all three impression techniques. However, mean dimensional change and SD for hydrophobic VPS were much higher with monophase, mere increase for 1-step and 2-step, than the standard steel die (p<0.05). Unpaired t-test displayed that hydrophilic VPS judged satisfactory compared to hydrophobic VPS among 1-step and 2-step impression technique. Conclusion: Within the limitations of this study, it can be concluded that hydrophilic Vinyl polysiloxane was more dimensionally accurate than hydrophobic Vinyl polysiloxane using monophase, one step and two step putty wash impression techniques under moist conditions. © 2016, Journal of Clinical and Diagnostic Research.
