Biological properties versus solubility of endodontic sealers and cements.

Endodontic sealers and cements used in root canal treatment have different compositions and properties. Common to all materials is that their primary goal is to fill gaps and voids, making a permanent seal of the root canal system. Furthermore, aspects such as antibacterial properties, cytotoxicity, setting time, solubility and biocompatibility are also crucial and ought to be considered.

Orthodontic management of traumatic dental injuries in Norway and orthodontists' perceptions of referral routines: A quality assurance survey.

The aims of this study were: (i) to describe how orthodontists perceive the information on traumatic dental injuries received by referral from the Public Dental Health Service before orthodontic treatment and (ii) to assess orthodontists' knowledge and working routines in managing traumatic dental injuries.

Materials And Methods: Data were obtained through a survey of all practicing orthodontists registered as members of the Norwegian Association of Orthodontists (n = 203).

Impact of Case Difficulty, Endodontic Mishaps, and Instrumentation Method on Endodontic Treatment Outcome and Quality of Life: A Four-Year Follow-up Study.

Introduction: Root canal treatment (RCT) is often considered a difficult procedure for both the patient and treatment provider. The American Association of Endodontists case difficulty assessment form categorizes cases as minimal, moderate, and high difficulty level. We recently showed that endodontic mishaps occur frequently during treatment of teeth in high difficulty category.

Background/aims: Traumatic dental injuries (TDI) occur frequently and may result in pulp sequelae. This includes pulp necrosis with infection, pulp canal obliteration and root resorption. The aim of this study was to assess the prevalence and risk factors of pulp sequelae after TDI among Norwegian adolescents.

Influence of the coronal restoration on the outcome of endodontically treated teeth.

The tooth weakens due to removal of hard tissue during an endodontic procedure. Many dentists find it difficult to choose between different coronal restorations after root canal treatment (RCT). Studies show that the coronal restoration may affect the endodontic prognosis.

The aim of this study was to evaluate and compare the effect of commonly used TSCs [mineral trioxide aggregate (MTA), Biodentine, and TotalFill] on cellular metabolism and osteogenic/angiogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) in vitro. We tested the null hypothesis of no difference between MTA, Biodentine, and TotalFill in stem cell responses.

The structured short questionnaire included items registering TDIs during 2009, existence of routines or guidelines for managing TDIs, previous relevant training, and request for TDI education or information.

Impact of low birthweight on early childhood caries in 6-36 months old infants in Uganda: A cross-sectional study.

Objective: Focusing on 6-36 months old infants, this study assessed (1) whether socio-economic status, current anthropometric status, presence of enamel hypoplasia, number of erupted teeth, oral hygiene and consumption of sugared snacks varied between children with normal birthweight (NBW) and low birthweight (LBW) and (2) the association between ECC and birthweight whilst adjusting for covariates of ECC, such as current anthropometric status.

Method: A cross-sectional study was conducted in Kampala in 2007, involving 816 child/caretaker pairs. All caretakers completed face-to-face interviews.

Developmental defects of enamel in primary teeth and association with early life course events: a study of 6-36 month old children in Manyara, Tanzania.

Background: Children with low birth weight show an increased prevalence of developmental defects of enamel in the primary dentition that subsequently may predispose to early childhood caries (ECC).Focusing 6-36 months old, the purpose of this study was to assess the frequency of enamel defects in the primary dentition and identify influences of early life course factors; socio-demographics, birth weight, child's early illness episodes and mothers' perceived size of the child at birth, whilst controlling for more recent life course events in terms of current breastfeeding and oral hygiene.

Methods: A cross-sectional study was conducted in the high fluoride area of Manyara, northern Tanzania including 1221 child-mother pairs who attended Reproductive and Child Health (RCH) clinics for immunization and/or growth monitoring.

Feeding practice among 6-36 months old in Tanzania and Uganda: reliability and relationship with early childhood caries, ECC.

Objective: To assess the reproducibility of caregivers' responses to dietary recall from birth and 24-h dietary recall with respect to infants' intake of sugared snacks and to assess whether those assessment methods provide comparable results for groups of infants. Re-test reliability and clinical covariates of time to first exposure of sugared snacks and time to termination of breastfeeding were also examined. It was hypothesized that time to first exposure/termination would vary according to socio-demographic profile and ECC.

Child- and family impacts of infants' oral conditions in Tanzania and Uganda-- a cross sectional study.

Background: Early childhood dental caries impacts on the quality of life of children and their families. This study set out to assess the psychometric properties of an oral health related quality of life, OHRQoL, measure, based on items emanating from the Child-and Family impact sections of the Early Childhood Oral Health Impact Scale (ECOHIS), in Kiswahili and Luganda speaking communities. It was hypothesized that the Child- and Family impact scores would discriminate between children with and without clinically defined dental problems and reported good and bad oral health.
