Developmental changes of the buccal teeth segments on the longitudinal dentitions during the period of buccal teeth exchange and the factors having effect on their dimensional changes were investigated by using three groups: normal group, group with good alignment in spite of the premature loss of the second deciduous molar and the group resulting ultimately in bad alignment. The dimensional ch...

Abstract This study aimed to assess the prevalence of tooth loss and associated factors in institutionalized adolescents. cross-sectional included 68 male adolescents incarcerated from Socio-Educational Assistance Center (CASE) aged between 15 19 years. Questionnaires were applied individually sociodemographical, economical, medical, behavioral oral health self-perception variables. All present...

The objective of this study was to present a classification of the root development stage of female rat molar teeth and to evaluate the variation in the lactate dehydrogenase (LDH) activity and electrophoretic isoenzyme profile according to the stage of root development of the molar teeth. We also studied the LDH activity and isoenzymes of the pulp of incisor teeth. The stage of development of ...

Incontinentia pigmenti achromians (IPA), first reported by Ito (Ito 1952), is a rare disease, involving the skin, hair, eyes, central nervous system, and musculoskeletal system. The cutaneous manifestations consist of macular hypopigmented whorls, streaks, and patches in a bilateral or unilateral distribution affecting almost any portion of the body surface. Central nervous system dysfunction, ...

From a selection of four kinds of post and core systems, including a fiber post and composite resin core, the purpose of this study was to determine the most effective system for the restoration of endodontically treated teeth with 0 mm of coronal tooth structure. For experimental abutment teeth, typical human maxillary central incisor teeth were modeled using bovine mandibular incisor teeth. B...

Rmoval of abscessed primary teeth has been sug;ested because they have been shown in some tudies to create developmental defects with underlying permanent successors.' However there might be a rationale for attempting pulp therapy in some carefully selected cases, i.e., abscessed incisor prior to eruption of primary cuspids, as space closure may occur. In necrotic immature teeth, the wide and f...

BACKGROUND Little information is available about the accuracy of the teeth mark on the laryngeal tube (LT) as a guide to correct placement in children. The aim of this crossover study was to evaluate three methods for optimal insertion depth of the size (#) 2 tube in children weighing 12-25 kg. METHOD In 24 children, the LT #2 was consecutively inserted by three different methods: (A) until t...

Objective: The aim of this study was to evaluate the effects of different curing times of a light-emitting diode (LED) on the bond strength of stainless steel brackets and to evaluate the temperature changes in the pulp chamber during curing of the composite. Materials and Method: Caries-free human first premolar and maxillary central incisor teeth extracted for orthodontic and periodontal reas...

PURPOSE Dentists' and parents' assessment of primary maxillary incisors regarding attractiveness, perceived health, and treatment preferences were investigated in this study. METHODS Sample groups of 103 general dentists, 67 pediatric dentists, 97 parents of children in low-income families and 112 parents of children in high-income families completed questionnaires presenting color photograph...

OBJECTIVES To obtain maxillary anterior tooth dimension and proportion values for the Central Chinese population and to evaluate the existence of sexual dimorphism, any consistent relationships between the tooth ratios, and the presence of golden proportions. METHODS Tooth dimensions and proportions of six maxillary anterior teeth were recorded on gypsum casts obtained from 147 subjects (82 w...
