OBJECTIVE: Amelogenesis imperfecta (AI) is a heterogenous genetic disorder that interferes with normal enamel formation in the absence of systemic disorders. The patients' main concerns are caries susceptibility, poor esthetics, and generalized sensitivity. There is a broad clinical spectrum, from discolorations to consequent enamel alterations. This case report describes the 15-year case study and the full-mouth rehabilitation of two siblings affected by a hypocalcified AI. Clinical Considerations: In these two patients, conservative care with stainless steel crowns and direct composite restorations was undertaken to restore function and esthetics and to reduce sensitivities in primary and mixed dentitions...

OBJECTIVE: The cross-arch space maintainers are used to prevent mesio-distal movement of teeth under physiologic forces, contrary to adult orthodontics where these are used as anchorage against orthodontic forces. Stresses in periodontal ligaments (PDL) are supposed to be different in pediatric dentistry and need to be studied. This study aimed to create mathematical model and calculated the initial stresses generated in the PDL and the behavior of movement in developing permanent maxillary first molar under masticatory forces using 3D finite element analyses (FEA)...

OBJECTIVES: We investigate intracemetery biological variation at the Fort Ancient SunWatch village (800-500 BP.) to test the hypothesis that the SunWatch population consisted of spatially structured biologically differentiated kin groups consisting of distinct local Late Woodland and non-local Mississippian biological populations. MATERIAL AND METHODS: The SunWatch sample contains 166 individuals: 63 adults and 103 subadults. We analyze intracemetery biological variation using two feature sets: the buccolingual diameters of the polar teeth in the permanent (n = 37) and deciduous (n = 26) dentitions...

Teeth have long served as a model system to study basic questions about vertebrate organogenesis, morphogenesis, and evolution. In nonmammalian vertebrates, teeth typically regenerate throughout adult life. Fish have evolved a tremendous diversity in dental patterning in both their oral and pharyngeal dentitions, offering numerous opportunities to study how morphology develops, regenerates, and evolves in different lineages. Threespine stickleback fish (Gasterosteus aculeatus) have emerged as a new system to study how morphology evolves, and provide a particularly powerful system to study the development and evolution of dental morphology...

BACKGROUND: Proximal dental lesions, limited to dentine, are traditionally treated by invasive (drill and fill) means. Non-invasive alternatives (e.g. fluoride varnish, flossing) might avoid substance loss but their effectiveness depends on patients' adherence. Recently, micro-invasive approaches for treating proximal caries lesions have been tried. These interventions install a barrier either on top (sealing) or within (infiltrating) the lesion. Different methods and materials are currently available for micro-invasive treatments, such as sealing via resin sealants, (polyurethane) patches/tapes, glass ionomer cements (GIC) or resin infiltration...

The aim of this study was to investigate the effects of the Swedish moist powder tobacco product known as "snus" on dental caries and to measure the pH fall in dental plaque. The subjects comprised male and female adults between 26 and 62 years of age (n = 102), all habitual snus users for ≥ 10 years. The control group (n = 101) consisted of similar individuals in terms of gender, age and educational level but with no tobacco use for ≥ 10 years. A clinical and radiographic examination and a questionnaire were completed...

BACKGROUND: Population health needs are changing. The levels of dental caries and periodontal disease across the population as a whole is falling. The proportion of adults with a functional dentition in many developed countries has increased substantially and edentulous rates have dropped to some of their lowest levels. Despite this, a pronounced social gradient still exists, many adults do not attend dental services regularly and disease in young children remains intransigent amongst the poorest...

Anti-dentin autoantibodies are associated with inflammatory root resorption in permanent teeth and are modulated by dental trauma and orthodontic force. However, it is not known whether deciduous tooth trauma can stimulate the development of a humoral immune response against dentin. The aim of this study was to evaluate the levels of salivary SIgA reactivity against human dentin extract in young adults with a history of trauma in the primary dentition. A sample of 78 patients, aged 18 to 25, who had completed an early childhood (0 to 5 years old) caries prevention program years earlier at the Universidade Estadual de Londrina Pediatric Clinic, underwent radiographic examination and salivary sampling...

Sex disparities in dental caries have been observed across many populations, with females typically exhibiting higher prevalence and more affected teeth. In this study we assessed the sex disparities in two Northern Appalachian populations from West Virginia (WV, N = 1997) and Pennsylvania (PA, N = 1080) by comparing caries indices between males and females across four phases of dental development: primary dentition in children aged 1-5 years, mixed dentition in children aged 6-11 years, permanent dentition in adolescents aged 12-17 years, and permanent dentition in adults aged 18-59 years...

BACKGROUND: Habits formed in childhood dictate lifestyle choices made as adults. These encompass both oral hygiene and dietary habits which in turn affect dental caries status. Children largely acquire these habits from modeling/observing parents and other family members. AIM: The purpose of this study was to assess the caries status of 5-year-olds, and evaluate associations between dental caries and family-related factors. MATERIALS AND METHODS: A cohort of 400 children were examined for dental caries using the WHO criteria...

Singleton-Merten syndrome (SMS) is an autosomal-dominant multi-system disorder characterized by dental dysplasia, aortic calcification, skeletal abnormalities, glaucoma, psoriasis, and other conditions. Despite an apparent autosomal-dominant pattern of inheritance, the genetic background of SMS and information about its phenotypic heterogeneity remain unknown. Recently, we found a family affected by glaucoma, aortic calcification, and skeletal abnormalities. Unlike subjects with classic SMS, affected individuals showed normal dentition, suggesting atypical SMS...

BACKGROUND: Aggregatibacter bacteria are a rare cause of endocarditis in adults. They are part of a group of organisms known as HACEK--Haemophilus, Aggregatibacter, Cardiobacter, Eikenella, and Kingella. Among these organisms, several Haemophilus species have been reclassified under the genus Aggregatibacter. Very few cases of Aggregatibacter endocarditis in patients with pacemaker devices have been reported. CASE PRESENTATION: We present here what we believe to be the first case of Aggregatibacter aphrophilus pacemaker endocarditis...

Children and adolescents are subject to a wide variety of gingival infections. Epidemiological studies indicate that gingivitis of varying severity is nearly a universal finding in children and adolescents. The shorter life span of the primary dentition may be the reason why in general little attention is given to periodontitis in children. Since early diagnosis is important for successful treatment, it is imperative that children receive a periodontal examination as part of their routine dental visit. Furthermore destructive periodontal disease occurs in children with certain systemic diseases...

AIM: Atypical swallowing is a myofunctional problem consisting of an altered tongue position during the act of swallowing. High incidence in population, multifactorial etiology and the recurring connection with the presence of malocclusions made it a topic of strong interest and discussion in science. The purpose of this review is to illustrate the current orientation on the topic of atypical swallowing, trying in particular to answer two questions: 1) what kind of connection is there between atypical swallowing and malocclusion; 2) what kind of therapy should be used to solve it...
