In humans, deciduous tooth development begins before birth and is complete by about the fourth postnatal year. They are lost when the patient becomes 11 years old. The permanent teeth appear by 6-7 years (and later for the wisdom teeth). Most are successional, and a few are non successional. The coronal part of the human tooth is composed of two hard tissues: enamel and dentin, and this part in...

Dentigerous cysts (DCs) are benign odontogenic cysts that are associated with the crowns of permanent teeth. The purpose of this study is to describe the management of DCs in four children. Four boys aged between 7 and 9 years were referred to our clinics with the complaints of intraoral alveolar swelling or facial asymmetry on the affected area. The panoramic radiographies showed large, well-d...

introduction: the aim of this randomized controlled trial was to compare the radiographic and clinical success rates of direct pulp capping (dpc) using proroot mineral trioxide aggregate (mta) or calcium enriched mixture (cem). methods and materials: a total of 42 symptom-free carious vital primary molars (21 pairs) were selected in this split mouth trial and randomly pulpotomized in two experi...

AIM The purpose of this report is to present two cases of totally impacted maxillary deciduous molars, considered a rarity in dental practice. BACKGROUND Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membra...

An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment.1 Frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have an anatomical variations or additional root canals.2 Supernumerary root is a developmental condition and may involve any tooth. The incidence of ...

OBJECTIVE The aim of the present study was to compare the beginning of eruption of the first deciduous tooth in preterm infants (<38 weeks) with full-term infants (38 and 42 weeks) of normal birth weight ((3)2.500g), low birth weight (< 2.500g) and very low birth weight (<1.500g), in order to evaluate if premature birth and low birth weight would affect tooth eruption. METHODS The neonatal re...

Morphological variations like additional roots and root canals in human deciduous dentition are rare. Knowledge of the morphology, variation of root and root canals of deciduous teeth are useful for successful endodontic treatment and exodontia. Presented here is a case report of the supernumerary roots and additional root canals of deciduous mandibular second molar (85) with congenitally bilat...

dentinogenesis imperfecta (di) is a hereditary dentin defect caused by an autosomal dominant mutation in dentin sialophosphoprotein gene. defective dentin development results in discolored teeth that are prone to wear and fracture. early diagnosis and proper treatment are necessary to achieve better functional and esthetic results and minimize nutritional deficiencies and psychosocial distress....

Deciduous teeth (dentes lactales, dentes decidua, dentes caduci) differ from permanent teeth by morphological and histological characteristics. Of the morphological characteristics, the most pronounced differences are in number, shape, size and color of teeth. A special fea­ ture is the existence of enamel­dentin ridge located on the vestibular surface of molars, which protects gingiva from foo...

objective: by date investigations have indicated the presence of stem cells within the pulp tissue of both temporary and permanent human teeth. in the present study, these stem cells were compared in terms of their growth kinetics and culture requirements. materials and methods: stem cells within the pulp of the human third molar (permanent tooth) and the deciduous incisor (temporary tooth) wer...
