Oral mucosa is susceptible to tissue injury from many causes, including infection, autoimmune disorders, surgical and accidental trauma, and gingival and periodontal inflammation; however, little is known about the events that influence wound healing in the mouth. This study investigated the changes in salivary thromboplastic activity prior to and after primary tooth extraction. Cytological sme...

BACKGROUND Methods for determining the root canal length of the primary tooth should yield accurate and reproducible results. In vitro studies show some limitations, which do not allow their findings to be directly transferred to a clinical situation. AIM To compare the accuracy of radiographic tooth length obtained from in vivo digital radiograph with that obtained from ex vivo digital radio...

The development of alveolar bone adjacent to the tooth root during tooth eruption is not well understood. This study tested the hypothesis that predominantly woven bone forms adjacent to tooth roots during tooth eruption, but that this immature structure transitions to lamellar bone when the tooth comes into function. Additionally, bone resorption was predicted to play a key role in transitioni...

Chorion type may significantly influence the prenatal environment of twins. This study explored the associations between chorion type and gestational age, birth weight, birth length, and the timing of emergence of the first primary tooth in two populations of twins, Australian and Dutch. Additionally, we investigated the relationship between chorion type and birth weight discordance (BWD) in or...

AIM To describe a pulpotomy with mineral trioxide aggregate in a primary second molar with no permanent successor. SUMMARY Coronal pulpotomy was performed on a carious primary molar with no permanent successor in a 7-year-old child. Follow-up examinations 24 months later revealed that the treatment was successful in preserving the tooth and the vitality of its pulp. KEY LEARNING POINT Miner...

We determine the relationship between premature loss of primary teeth and oral hygiene, consumption of soft drinks, dental care and previous caries experience. This study focused on 833 Mexican schoolchildren aged 6-7. We performed an oral examination to determine caries experience and the simplified oral hygiene index. The dependent variable was the prevalence of at least one missing tooth (or...

RELATED TO DENTAL DEFECTS CAUSING TOOTH LOSS Tooth agenesis is the most prevalent craniofacial congenital malformation in humans. Up to 25% of the population may lose at least one third molar. Agenesis of other permanent teeth, excluding third molars, ranges from 1.6 to 9.6%, depending on the population studied. Primary dentition may also be affected, but with lower prevalence (from 0.5 to 0.9%...

The purpose of this study was to validate the elastomeric impression after temporary tooth separation as a method of cavitation detection in proximal caries lesions in primary molars with outer half dentin radiolucency. Fifty-one children (4-10 years old), presenting radiolucency in the outer half of the dentin at the proximal surfaces of primary molars and proximal anatomic contact with the ad...
