The article reports the case of a 53-year-old male patient, who went to the Clinic of University Dental Services (SERODU), in Ecuador, for presenting a gingival smile. He had no relevant medical history. He was diagnosed with a gingival enlargement of teeth 1.1, 1.2 and 2.1 and was treated with high intensity diode laser gingivoplasty. After 15 days of control, good healing was observed and the patient stated that he had no postoperative pain.The objective of this clinical case is to show the benefits of the high intensity diode laser, for the treatment of gingival enlargement and thereby achieve a better aesthetic perception of the upper anterior teeth.

South American (SA) societies are highly vulnerable to droughts and pluvials, but lack of long-term climate observations severely limits our understanding of the global processes driving climatic variability in the region. The number and quality of SA climate-sensitive tree ring chronologies have significantly increased in recent decades, now providing a robust network of 286 records for characterizing hydroclimate variability since 1400 CE. We combine this network with a self-calibrated Palmer Drought Severity Index (scPDSI) dataset to derive the South American Drought Atlas (SADA) over the continent south of 12 degrees S. The gridded annual reconstruction of austral summer scPDSI is the most spatially complete estimate of SA hydroclimate to date, and well matches past historical dry/wet events. Relating the SADA to the Australia-New Zealand Drought Atlas, sea surface temperatures and a...
