Early onset of enamel formation in Baka pygmy's deciduous canines.

Objective: Our aim was to evaluate by enamel microstructure analysis two hypotheses that would explain the early dental eruption in the Bakaparticularity, a shorter crown formation time and/or earlier onset of crown formation.

Design: Deciduous canines corresponds to the best teeth to perform the analysis of enamel microstructure. Longitudinal ground sections of 21 deciduous canines from 12 individuals were studied with transmitted light microscopy.

Clinical and Radiographic Evaluations of Biodentine™ Pulpotomies in Mature Primary Molars (Stage 2).

Introduction: The preservation of the integrity and health of primary teeth and their supporting tissues is of great importance in maintaining arch length space, mastication, speech, and esthetics. A pulpotomy is a common therapy performed on a primary tooth presenting reversible pulpitis or a traumatic pulp exposure, allowing its conservation on the arch until its loss.

Aim: The study aims to clinically and radiographically evaluate the rates of success and efficacy of Biodentine™ as pulpotomy medicament exclusively on deciduous molars with complete roots formation (stage 2).

Evaluation of Biodentine Pulpotomies in Deciduous Molars with Physiological Root Resorption (Stage 3).

Introduction: Conservation of primary dentition is essential for maintenance of arch length, esthetic, mastication, speech and prevention of abnormal habits. The commonly supported treatment for retaining carious primary molars with affected pulp is pulpotomy.

Aim: The study aims to evaluate clinically and radiographically the rates of success and efficacy of Biodentine™ as pulpotomy medicament exclusively on primary molars with physiological root resorption.

Caries experience and related factors in 4-6 year-olds attending dental clinics in Kinshasa, DR of Congo.

Objectives: The aim of this study was to examine the prevalence and severity of caries experience (CE) in 4-6 year-olds attending dental clinics in Kinshasa, DR Congo, and to explore possible associations with reported behavioural and socio-demographic factors.

Methods: A convenience sample of children attending five dental clinics was recruited. Carers, usually parents, completed a questionnaire consisting of socio-demographic information, oral health and tobacco consumption profile of parents, socio-economic family situation and oral health habits of the child.

Caries risk management: effect on caries incidence in a sample of Lebanese preschool children.

Objectives: This clinical prospective study describes how caries preventive measures applied according to caries risk affect new caries incidence in a group of preschoolers, as compared to a group where standardized caries prevention is applied, regardless of risk.

Method And Materials: Healthy children, aged four years or less, recruited at the Faculté de Médecine Dentaire, Université Saint-Joseph, Beirut, Lebanon were assigned, after parental consent, to an experimental or a control group. Caries risk was determined based on a parental questionnaire, salivary levels of Steptococcus mutans (Sm) and Lactobacillus (Lb), salivary buffer capacity, plaque levels and carious lesions prevalence, then subjects were classified into four caries risk categories.
