In patients with CP, a single application of PDT (using a 638-nm laser and toluidine blue) did not provide any additional benefit to SRP in terms of clinical parameters or inflammatory markers 3 months following the intervention.

Purpose. The aim of this study was to evaluate the efficacy of anorganic bovine bone (Bio-Oss) in comparison with nanocrystalline hydroxyapatite (Ostim) in sinus floor augmentation. Methods. Ten patients aged 40–80 were selected. All the patients needed sinus floor augmentation due to insufficient bone for simultaneous implant placement. The patients underwent panoramic radiography and cone beam computed tomography (CBCT) prior to surgical procedure. After lifting the sinus membrane, Bio-Oss and Ostim are randomly grafted at one of the two sides. Biopsies were obtained from areas identified 5 months after the surgery and before implant placement and then were prepared for histological analysis. Statistical analysis was performed with nonparametric Wilcoxon signed-rank test for comparison of histological and radiological parameters between the two groups. Results. Histological findings revealed a significant increase in percentages of new bone in the Ostim group (P = 0.015). Furthermore, new bone density was greater with Ostim compared to Bio-Oss (P = 0.038); however, the difference in height increase after surgery did not reach statistical significance (P = 0.191). Conclusion. Despite the limitations of this trial, Ostim and Bio-Oss are useful biomaterials in sinus augmentation and Ostim seems to be even more effective in new bone formation.

The Sturge-Weber syndrome or encephalotrigeminal angiomatosis is a rare neurological and congenital disorder with a frequency of 1 in 50,000 births. This syndrome is a nonhereditary developmental condition and is characterized by the presence of congenital capillary malformation and a hamartomatous vascular proliferation involving the face (port-wine stain or facial birthmark), sometimes skull and the tissues of brain, jaws, oral soft and hard tissues and rarely other body organs. Seizures, mental retardation, and cortical calcification (tram-tracks) and congenital glaucoma may be seen in this syndrome. We report here a 40-year-old female with Sturge-Weber syndrome associated with bilateral cutaneous capillary malformation on her face, neck, hands and feet and also gingival enlargement.
