The purpose of this study was to determine characteristics of soft-tissue profile in peruvian adults using Holdaway linear and angular measurements. It was also the purpose of this study to compare the collected data with the Caucasian norms of Holdaway. The sample consisted of 40 untreated adults (20 males and 20 females) between 18 to 30 ages. The subjects selected were in good health and had normal occlusion. Lateral cephalogram x-rays were taken with the teeth in occlusion. The findings indicated that the most of linear and angular values were significantly different from those of the Holdaway analysis. The angle “H” in the Peruvian sample was 8.45° more than that of the American. Caucasian group.

This investigation evaluated the behavior of permanent inferior incisives after the primary canine’s extractions. The study was carried out in the Pediatric Clinic of Dental Faculty of San Marcos University. The sample was conformed by 10 patients, male and female children, between 8 and 9 years of age, with good general health, having Class I malocclusion and severe crowding of the inferior incisives. It was taken Cephalometric and Panoramic radiographies, as well as models to make the orthodontic diagnoses and select the cases. To evaluate changes that took place in the area, models were prepared 3 months after extractions, having as a result: a complete correction of the inferior tooth crowding in 50% of the cases, a partial correction in 40% and any correction in 10%.

It determine the sequense of eruption of permanent mandibular teeth, cusp, first bicusp and second bicusp, using a cross-sectional in a random sample of 67 child patients, 33 males and 34 females between 8 and 12 years old that where attended at Dentistry clinic of the Dentistry Faculty of the San Marcos Mayor National University between 2006 and 2011. For this study where used odontologic casts, pictures and panoramic radiographs of the patients. Relevant results where that for males and females, the sequence of eruption that predomine was 3, 4, 5
