The research was conducted with the objective of defining the concentration of lead in deciduous dental enamel according to gender, age, and severity. Thirty-five microbiopsies were performed on the dental enamel of 35 children from the Quichas community; the sampling was non-probabilistic and convenient. 100% of the children had lead levels in their dental enamel. The results show lead concentrations ranging from 5.65 to 12.83 μg/g in children between 4 and 6 years of age. A significant relationship was demonstrated between lead concentration and age. It was concluded that the median concentrations are higher as age increases. Regarding the severity of lead concentration, it was found that 94.3% of the children had moderate concentrations (5 μg/g-10 μg/g) and 5.7% had severe concentrations (10 μg/g or higher). However, no statistically significant differences were found according to gender. It is recommended to further study the concentration of lead in dental enamel, analyze lead levels in blood and saliva, conduct studies on permanent teeth, and compare lead concentrations in deciduous and permanent teeth.

The objective of this study was to determine the relationship between the level of parental knowledge about oral hygiene and its relation to the oral hygiene of children aged 3 to 5 years at the IEP "Angelitos de Jesús", Lima - 2015. The study was descriptive, prospective, observational, and cross-sectional. The population consisted of 138 children and their respective parents. The IHOs (Simplified Oral Hygiene Index by Green and Vermillion) was used on the children, and a questionnaire consisting of 10 questions related to oral hygiene, previously validated by expert judgment, was used for parents. The results showed that the IHOs was 65.00% for 3-year-olds and 42.50% for 5-year-olds, considered as poor oral hygiene; while 75.00% of 4-year-olds had regular oral hygiene. The level of parental knowledge about oral hygiene, according to age, was poor in 50.00% of parents aged 31 years and older. Regarding gender, the male gender had a higher prevalence, with 66.67% of males showing poor knowledge. The study concluded that there is no relationship between the level of parental knowledge about oral hygiene and the oral hygiene level of children aged 3 to 5 years at IEP "Angelitos de Jesús", Lima - 2015.

The purpose of this research was to analyze the study models of students aged 12 to 16 years at the Huaycán Mixed School to compare the predictive accuracy of the Moyers and Tanaka Johnston analyses. The study was prospective and analytical, with an applied level. The sample consisted of study models from 50 students who met certain inclusion criteria. Data processing was performed using the Wilcoxon test for related samples, with a 95% confidence level. The results showed a significant difference with the Moyers probability at 75% and 85%, in both genders and both maxillae. The difference was not significant for the male gender, with 95% in both arches. Regarding the Tanaka Johnston probability at 75%, a significant difference was found in both genders and maxillae, compared to the 85%, where there was no significant difference for the female gender, but a significant difference for the male gender, in both maxillae. In conclusion, the results suggested that the Moyers probability at 95% should be applied to the upper and lower maxillae for males, and the Tanaka Johnston equation at 85% for the upper and lower maxillae for females, since there are no statistically significant differences.

Cleft Lip and Palate (CLAP) is one of the most common congenital malformations, resulting from a disruption in the fusion of the tissues that form the upper lip and palate during embryonic development. This study aimed to determine the frequency of congenital dental anomalies related to variations in number, size, and shape in patients with cleft lip and palate treated at the Hospital Nacional Docente Madre Niño San Bartolomé, Peru, in 2015. The study was conducted with 52 patients aged 1 to 7 years with cleft lip and palate from June to November 2015, using clinical observation, panoramic radiographs, and medical history. It was a prospective, cross-sectional, descriptive, and observational study. The results showed that 19.2% of the sample had an incomplete unilateral left cleft, with a male predominance at 13.5%. The most common dental anomaly was dental agenesis, at 63.5%, followed by microdontia at 26.9%, and 30.8% of patients had dental alterations. Regarding cleft type, 15.4% had incomplete unilateral left and right clefts associated with dental agenesis, 9.6% had incomplete unilateral left clefts associated with microdontia, and 7.7% had bilateral clefts with shape alteration. It was concluded that there is a significant difference when associating the number of dental anomalies with cleft type, where dental agenesis was most prevalent in complete unilateral right and left clefts.
