This study evaluated the influence of Psidium cattleianum Sabine (Myrtaceae) and Myracrodruon urundeuva Allemão (Anacardiaceae) aqueous extracts on S. mutans counts and dental enamel micro-hardness of rats submitted to a cariogenic challenge. Sixty Wistar rats were distributed in three groups and received water (control) or aqueous extracts of Psidium cattleianum or Myracrodruon urundeuva as hydration solution. Initially the animals had their sublingual and submandibular salivary glands surgically removed and the parotid ducts ligated. Then the rats were inoculated with 106 CFU of Streptococcus mutans ATCC 35668 and were fed with a cariogenic diet. To detect and quantify the presence of S. mutans, oral biofilms were sampled and microbial DNA was extracted and submitted to amplification by means of real-time PCR (Polymerase Chain Reaction). After seven weeks the animals were sacrificed and enamel demineralization was analyzed by cross-sectional micro-hardness. Both extracts produced a significant reduction on S. mutans counts and decreased the enamel demineralization. It can be concluded that the extracts tested had a significant effect on S. mutans in oral biofilm of the rats, decreasing S. mutans accumulation and enamel demineralization.

The sialolithiasis is characterized by the formation of calcified structure called sialolith within the salivary ductal system. Although its etiology is unknown, it is believed that is from the deposition of calcium salts around an accumulation of organic leftovers in the lumen of the duct or be resulted by chronic sialadenitis and partial obstruction. In this study, the authors describe a case of a male patient, 46 years old, brown, who presented the complaint “pain under the tongue.” The presence of a hardened nodule located in the left sublingual fold was observed through intra-oral exam. Current considerations about treatment, clinical and radiographic characteristics were addressed in this work.
