Taurodontism is a relatively rare variance with a very low incidence in primary dentition and only a few cases have been reported in the literature. It stands a challenge when these teeth require pulp therapy. This case report illustrates the oral rehabilitation of multiple primary molars with taurodontism involving both the maxillary and mandibular arches, which is a rare occurrence.

REVIEW
Nak Heon Kang
Alveolar cleft is a tornado-shaped bone defect in the maxillary arch. The treatment goals for alveolar cleft are stabilization and provision of bone continuity to the maxillary arch, permitting support for tooth eruption, eliminating oronasal fistulas, providing an improved esthetic result, and improving speech. Treatment protocols vary in terms of the operative time, surgical techniques, and graft materials. Early approaches including boneless bone grafting (gingivoperiosteoplasty) and primary bone graft fell into disfavor because they impaired facial growth, and they remain controversial...

The World Health Organization (WHO) stated that globally, dental caries is the most important oral condition. To develop effective prevention strategies requires an understanding of how this condition develops and progresses over time, but there are few longitudinal studies of caries onset and progression in children. The aim of the study was to establish the pattern of caries development from childhood into adolescence and to explore the role of potential risk factors (age, sex, ethnicity, and social deprivation)...

INTRODUCTION: One of the critical steps in the process of identification is the sex determination of an unknown individual. Many studies have shown that sex can be determined using the human skeleton, especially by examining the pelvis and skull. Odontometric analysis of the human sexual variation has been less investigated, especially of primary dentition. AIM: To verify the presence of sexual dimorphism in primary teeth of local population of Faridabad, Haryana, India...

Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care...

Although children with oral clefts have a higher risk for dental anomalies when compared with the general population, prior studies have shown conflicting results regarding their dental decay risk. Also, few studies have assessed dental decay risk in unaffected relatives of children with clefts. Thus, the question of increased risk of dental decay in individuals with oral clefts or their unaffected relatives is still open for empirical investigation. This study characterizes dental decay in the largest international cohort to date of children with nonsyndromic clefts and their relatives, as compared with controls, and it addresses whether families with oral clefts have a significantly increased risk for dental decay versus the general population...

Mythri Sarpangala, Ashwin Devasya
Morphological variations are seen in both primary and permanent dentitions. Cusp of Carabelli is also one of them. It is suggested that it is due to over activity of dental lamina but definitive aetiology is unknown. It is a type of accessory cusp, occurs more often in permanent maxillary first molars, whereas, its occurrence in primary tooth is rare. The present case series discusses the presence of cusp of Carabelli in primary maxillary second molars in three different cases. This case series will help clinicians to identify, diagnose and take proper preventive care and also adds to the incidence in literature...

Vertebrate dentitions are extraordinarily diverse in both morphology and regenerative capacity. The teleost order Tetraodontiformes exhibits an exceptional array of novel dental morphologies, epitomized by constrained beak-like dentitions in several families, i.e., porcupinefishes, three-toothed pufferfishes, ocean sunfishes, and pufferfishes. Modification of tooth replacement within these groups leads to the progressive accumulation of tooth generations, underlying the structure of their beaks. We focus on the dentition of the pufferfish (Tetraodontidae) because of its distinct dental morphology...

Amelogenesis imperfecta (AI) is a tooth disorder characterized by the abnormal development of the enamel in response to mutations in the genes involved in amelogenesis. The objective of this article is to present the clinical case of a child with AI in the primary dentition phase. A 4-year-old boy was presented to a clinic by his mother, who complained that her son's smile esthetics were compromised by "weak and yellow teeth." All the teeth showed yellowish discoloration as well as crumbling or missing enamel...

Severe dental trauma-such as intrusion or avulsion-to the primary dentition in infants and toddlers may cause developmental disturbances in the permanent successor. In this case, a 9-year-old boy was referred for treatment due to the absence of his permanent maxillary right central incisor. The mother reported avulsion of the corresponding primary tooth when the patient was 2 years old. The radiographic examination revealed impaction and root dilaceration of the permanent tooth; therefore, the treatment plan was tooth extraction...
