Gorlin-Goltz syndrome (GGS) is a rare autosomal dominant disorder. The disease shows multiple organ involvement with variable clinical presentation. Thus a multidisciplinary approach is required for its prompt clinical diagnosis and management of this condition. This paper highlights a case of GGS presenting in a young male patient with cranial, facial, dermatological, dental and skeletal involvement. The diagnosis of the syndrome was based on its clinical presentation, radiological features and histopathological findings. A review of the diagnostic criteria is also presented.

Statement of problem:Single maxillary complete denture fracture along the midline due to crack initiation and propagation from stressed areas in shallow palatal vault configuration. Therefore, it is important to use mesh in single denture fabrication. Aims and objectives:To investigate the mechanical fracture strength of acrylic resin denture base materials using four different mesh designs on shallow palatal vault configuration. Materials and methods:One type of heat-cured resin denture base materials was used to fabricate specimens. Shallow palatal vault shape stainless steel mold was used to aid in duplicating and standardizing the samples. A total of 100 samples were fabricated with high-impact acrylic resin denture base material using shallow palatal vault configuration and square mesh of dimension 50 × 40 mm was used and samples were divided into 5 groups of 20 samples, and each group contained different mesh designs. These samples were stored in water at room temperature for 4 weeks and will be subjected to fracture test using universal testing machine. Results:Samples with different four mesh designs, among them there was no significant difference, but fracture strength value of 4 ×4 mm mesh design was slightly more than other groups. Conclusion:The shallow palatal vault denture base is inherently weaker and less resistant to fracture. Thus, it is recommended to use stainless steel metal mesh in shallow palatal vault to increase fracture resistance. As there was no statistical difference among different mesh designs (i.e., different dimensions of each square in the mesh), any dimension of each square in the mesh can be used without making much statistical difference.

This review discusses giant cell lesion with main focus on central giant cell granuloma of jaw. Review of the lesion with regard to its nomenclature, pathogenesis and its clinical, radiological & histopathological features is presented. Surgical therapy along with recently reported conservative management protocol is discussed in detail.

BACKGROUND Although the metal-ceramic system is still widely used to fabricate crowns and fixed partial dentures, and is considered as the standard treatment in dentistry, aesthetic concerns have stimulated the development of new dental tooth-coloured systems such as PEEK. So, the present study was planned to check the marginal fit accuracies of conventional Porcelain Fused to Metal (PFM) crowns and Polyether Ether Ketone (PEEK) crowns. METHODS Based on the inclusion and exclusion criteria, sample size of 80 patients was considered. Out of 80 patients, 40 patients (Group I) received PFM crowns and 40 patients received PEEK (Group II) crowns. The marginal fit accuracy of crowns was checked using stereomicroscope. CBCT of the same patient with the crown was made to validate the readings obtained using stereomicroscope. RESULTS Data was analysed with the SPSS (Statistical Package for Social Sciences) version 17. Comparison of the two groups for marginal gap was done with unpaired 't' Test. For all the above tests, p value is considered statistically significant when it was ≤0.05. Four points were considered to measure the marginal gaps i.e., MB (Mesiobuccal), ML (Mesiolingual), DB (Distobuccal), DL (Distolingual). The highest marginal gap in the group I was at Mesiobuccal (MB) point i.e. 120.280000 microns and lowest marginal gap was at Distolingual (DL) point i.e. 110.127050 microns. It can be noted from CBCT that the marginal gap present in PFM crown is much greater than the PEEK crown. CONCLUSIONS Comparing the marginal fit accuracy between PFM and PEEK crowns based on the stereomicroscope readings, the marginal fit accuracy in PEEK crowns were much higher than the PFM crowns.
