objective: this study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel.   methods: this in vitro, experimental study was conducted on 24 sound primary teeth. the teeth were polished with a fine abrasive paper under running water. tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and sto...

Background: Traumatic injuries to the primary dentition are a frequent occurrence in children during the preschool ages of 1 to 4 years and are primarily due to falls. Developmental disturbances to the permanent teeth can occur from trauma to the primary dentition, resulting in hypoplastic defects and disruptions in eruption. The aim of this clinical case report was to demonstrate that developm...

Caries in very young children known as early childhood caries may be defined according to the American Academy of Pediatric Dentistry as “the presence of one or more decayed, missing (due to caries), or filled tooth surfaces in any primary tooth in a child 71 months of age or younger” (1,2). Early Childhood Caries (ECC) is a complex disease, which involves maxillary primary incisors within a mo...

 Abstract Introduction: Considering the importance of anterior teeth in chewing, speaking and esthetics, as well as the high prevalence of crown fracture among various traumatic injuries to the teeth, this study aimed to evaluate the etiology and risk factors associated with crown fractures of anterior teeth in 7-12 years old children. Materials and Methods:This descriptive cross-sectional ...

to evaluate the interfacial morphology and the bond strength produced by the three-step, two-step and single-step bonding systems in primary teeth.occlusal surfaces of 72 extracted human deciduous teeth were ground to expose the dentin. the teeth were divided into four groups: (a) scotchbond multipurpose (3m, espe), (b) adh se (vivadent), (d) optibond all-in-one (kerr) and (e)futurabond nr (voc...

We performed measurement using a 3-dimensional measurement system in study models of children with anterior crossbite in the primary dentition treated using a chin cap and lingual arch, and evaluated changes in the dentition and occlusion after treatment based on measurement values and also using wire frame models. Comparing with the situation before treatment, the overbite of anterior teeth sh...

The talon cusp, or dens evaginatus of anterior teeth, is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusplike structure projecting from the cingulum area or cementoenamel junction. This occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. This article reports five cases of talon cusp, two of them bi...

Restoration of severely decayed primary anterior teeth is often considered as a special challenge by pedodontists. This case report presents a 5-year-old boy with severely damaged maxillary right canine. Subsequent to root canal treatment, a reversed (upside-down) metal post was put into the canal and composite build-up was performed. This new method offers a simple, practical and effective pro...

Supernumerary teeth are among the most common dental anomalies affecting the primary and permanent dentition. They are usually found in the anterior maxilla and occur infrequently in the primary dentition. The purpose of this paper was to report a case diagnosed with primary supernumerary tooth in the primary second molar region. The crown and root shape of the primary supernumerary tooth resem...

objective: the aim of this study was to evaluate and compare the cleaning ability and instrumentation time of manual and rotary methods used for preparation of primary anterior teeth. materials and methods: forty-four primary anterior teeth were used in this experimental study. access cavities were prepared and india ink was injected into the canals. the samples were divided into three groups a...
