Oral Habits in Childhood and Occlusal Pathologies: A Cohort Study.

Purpose: To analyse the relationship between the different habits that occur in childhood and the different malocclusions in the three planes of space.

Material And Methods: A clinical examination of 106 children between 5 and 12 years of age was carried out and a survey validated by professors of the Faculty of Dentistry of the University of Seville was made for the parents in order to identify the habits and relate them to the possible malocclusions detected in the child's mouth.

Results: 72.

Shear bond strength of a self-etching adhesive in primary and permanent dentition.

Purpose: To assess the shear bond strength obtained with a new self-etching adhesive material (Adper Prompt-L-Pop) compared with the total-etch technique and posterior application of an adhesive (Prime & Bond NT) in both primary and permanent teeth.

Methods: 28 human teeth were selected (14 primary and 14 permanent). The vestibular and lingual surfaces were prepared in dentin, followed by application of the adhesive materials (Adper Prompt-L-Pop and Prime & Bond NT), in accordance with the instructions of the manufacturer.

New oral findings in Cohen syndrome.

Cohen syndrome is a hereditary disorder transmitted as an autosomal-recessive trait. Approximately 100 cases have been reported in the genetic and pediatric literature. Despite the fact that oral alterations are often observed in these cases, only 1 work has been published addressing this specific topic, and it tended to concentrate on periodontal abnormalities.

Marginal microleakage of two fissure sealants: a comparative study.

Purpose: An in vitro study was conducted to evaluate enamel marginal microleakage following acid etching of two fissure sealants of established clinical efficacy. The purpose of this study was to assess sealant leakage following etching in combination with the use of latest-generation adhesives.

Methods: Clinicians removed 22 human premolars without caries for orthodontic reasons, stored them in distilled water, and sealed the occlusal surface.
