the permanent successor is present, eruption of a submerged tooth may be delayed or redirected from its normal path into a malaligned position. If the permanent successor is absent, loss of dental arch space is likely, and a midline discrepancy may occur because the mesiodistal width of the primary submerged tooth is greater than that of the contralateral premolar. Also, overeruption of the opp...

Although the incidence of tooth decay has decreased considerably over the past two decades, the prevalence of caries among children and adolescents remains high. Minorities and low-income populations experience more dental decay than those with higher incomes, and they are also more likely to have a higher proportion of untreated decayed teeth. Low oral health care utilization is the primary re...

Recently we reported ultrastructural observatlons which indicated that matrix vesicles were actual constituents of the intercellular organic matrix during embryonic tooth development (14). It is assumed that many of these matrix vesicles are involved in formative aspects of dentinogenesis or amelogenesis, two primary extracellular processes that occur during embryonic tooth formation The fracti...

Background and Aim: Management of iron-induced tooth pigmentation is challenging. This study aimed to compare the efficacy of sodium bicarbonate powder and pumice flour for removal of iron-induced pigmentation from primary ante-rior teeth. Materials and Methods: In this in vitro, experimental study, 60 sound primary anterior teeth were collected. After cutting the roots and sealing the pulp ch...

The theme for the second National Dental Health Week was a logical sequel to the first namely, “ Plaque the Tooth Enemy”. This theme was aimed at intro­ ducing the public to the major causative factor in dental caries and periodontal disease. Although the public of all ages was to be exposed to the health education facts concerning “ Plaque the Tooth Enemy”, the main target group was the child ...

Early recognition of dental erosion is important to prevent serious irreversible damage to the dentition. This requires awareness of the clinical appearance of erosion compared to other forms of tooth wear. An understanding of the etiologies and risk factors for erosion is also important. These form the basis of a diagnostic protocol and management strategy that addresses the multifactorial nat...

Dilaceration of the permanent tooth usually is a consequence of traumatic injuries to the primary teeth. Although it may appear anywhere in the long axis of the tooth, i.e., crown, cementoenamel junction, or root, most often the root is involved. However, crown dilaceration is a rare condition representing 3% of the total injuries. Maxillary incisors are more susceptible to such injury and affe...

Childhood has been recognized as high-risk period for dental injuries and intrusion is one of the most common types of trauma to primary dentition. These injuries require the dentist to carefully examine not only the damaged tooth but possible sequelae to the permanent tooth germ and the overall health of the child. The present case report describes the treatment of a 3 years old child with com...

Odontoclastic root resorption is a significant clinical issue in relation to orthodontic tooth movement, and resorption of the roots of primary teeth is an intriguing biological phenomenon. The functional coordination of the OPG/RANKL/RANK system seems to contribute not only to alveolar remodeling, but also to resorption during orthodontic tooth movement and physiological root resorption. Serum...
