In this study, the process of osseointegration on titanium implant surfaces with different physicochemical treatments subjected to a simulated corporal fluid submersion was evaluated using the concept of fractal dimension. It was found that different treatments led to rather different calcium phosphate crystal growth patterns, with fractal dimension ranging from 1.68 to 1.93. The observed crystal patterns may be explained by a general deposition, diffusion, and aggregation growth mechanism, where diffusing particle sticking probability plays a fundamental role.

The objectives of this study were to determine the effectiveness of a mucoadhesive tablet of pilocarpine, 5 mg, for the treatment of xerostomia and verify its pharmacokinetic profile. The randomized, double-blind, crossover clinical trial involved 25 older adults (60 to 80 years) with xerostomia and hyposalivation who were randomly divided into groups A and B. Once daily, for 7 days, group A used a mucoadhesive tablet containing pilocarpine, while group B used a mucoadhesive tablet without the active ingredient (first intervention). After 7 days of washout (no treatment), use of the medications resumed for 7 days, with a crossover between groups (second intervention). Xerostomia was evaluated through a shortened version of the Summated Xerostomia Inventory-Dutch Version, and the unstimulated salivary flow (USF) and stimulated salivary flow (SSF) of the patients were measured. The patients were evaluated at baseline and 7,14, and 21 days. Then, the pharmacokinetic profiles of mucoadhesive and conventional oral pilocarpine tablets were compared using saliva obtained from 8 patients. Both of the interventions resulted in a significant reduction in Summated Xerostomia Inventory scores and a significant increase in the mean USF (P < 0.05). A statistically significant Increase in the mean SSF only occurred when pilocarpine was administered (P < 0.05). No significant adverse effects were found. The mucoadhesive tablet resulted in much higher salivary concentrations of pilocarpine than did the conventional oral tablet. Both formulations of the mucoadhesive tablet, with or without pilocarpine, relieved patients' dry mouth symptoms. Trial registration: Registro Brasileiro de Ensaios Clínicos (ReBEC) No. RBR-9qdnws.

Schwannomas are uncommon benign tumors arising in the nerve-supporting Schwann cells. Intraoral lesions usually present in the tongue or floor of the mouth as a submucosal nodule, while the palate is rarely affected. A 26-year-old white man presented with an asymptomatic submucosal fibroelastic nodule in the hard palate. The 2 x 2-cm lesion was covered by normal-appearing mucosa. Under the working diagnosis of minor salivary gland tumor, an incisional biopsy was performed, and analysis revealed an encapsulated tumor with a well-defined biphasic pattern: hypercellular areas with spindled cells arranged in palisades and less cellular areas formed by irregular arranged masses of elongated cells and fibers. The diagnosis of schwannoma was rendered, and the lesion was excised together with periosteum. No recurrence was observed after 30 months of follow-up. Palatal nodules usually present as minor salivary gland tumors; rarer lesions, such as schwannomas, represent a clinical diagnostic challenge. Clinicians should consider schwannoma in the differential diagnosis for palatal nodules and manage them with incisional biopsy and prompt treatment. [ABSTRACT FROM AUTHOR]

Lasers demonstrate excellent therapeutic action and are often employed in dentistry for the treatment of diverse clinical conditions. The aim of this study was to compare the efficacy of neodymium-doped yttrium-aluminum- garnet (Nd:YAG) laser, gallium-aluminum-arsenide (GaAlAs) laser, and 2% neutral fluoride gel in the treatment of dentinal hypersensitivity. Twenty-three patients were evaluated, involving a total of 48 quadrants with at least 1 tooth with dentinal hypersensitivity (89 teeth total). Pain intensity was recorded on a visual analog scale at the time of clinical examination (baseline), immediately after treatment, and 1 week posttreatment. Teeth were treated with 60 seconds of 2% neutral fluoride gel application or 60 seconds of laser treatment--Nd:YAG laser at a distance of 0.5 cm (unfocused; 1 W and 10 Hz for 60 seconds, perpendicular to the cervical surfaces) or GaAlAs laser in contact (40 mW; 4 J/cm²; spot: 0.028 cm²; 15 seconds per point on 4 points [mesial, medial, distal, and apical])--as well as sham treatments so that patients remained blind to their treatment group. All treatments provided adequate pain reduction immediately posttreatment, but laser treatments resulted in significantly greater reductions in pain intensity. [ABSTRACT FROM AUTHOR]

Objective: To determine the prevalence of syphilis and the associated risk factors in a female prison unit. Methods: This was a cross-sectional study including 113 women whom data were collected in two stages: first, blood test to check for syphilis seropositivity; and then collection of information through a form to assess risk situations for sexually transmitted infections. Results: Overall, syphilis prevalence was found to be 22.1% among the female prison population (n=25) and 28.6% among pregnant women. A statistically significant relationship was found between syphilis infection and previous history of sexually transmitted infections (p=0.04). However, most participants diagnosed with the disease were unaware of a history of sexually transmitted infection in the last 12 months (n=20/80.0%). The use of condom with fixed partners was considered to be a protective factor (odds ratio of 0.76; 95% of confidence interval 0.68-0.85). Conclusion: The prevalence of syphilis among the female prison population was high, particularly among pregnant women. Preventive and therapeutic measures as well as appropriate prenatal care can minimize the impact of syphilis in prison systems and, consequently, improve such health outcomes nationwide.

Melanin impregnation in squamous cell carcinoma (SCC) is an uncommon histological finding. Rare nonmelanocytic entities were previously described as having melanocyte colonization. A 57-year-old Brazilian woman was referred with a pigmented lesion in the lower lip and alveolar ridge with a prior clinical diagnosis of melanoma. The incisional biopsy of the tumor revealed an SCC with strong colonization of melanocytes in the stroma. The authors report a case of an unusual SCC variant and a brief review of the literature.
