Consanguinity-related hyperdontia: An orthopantomographic study

Background: The aim of this retrospective study was to describe the distribution of the non-syndromal supernumerary teeth (NSST) in a population of patients who attended the clinics of Riyadh Colleges of Dentistry and Pharmacy (RCsDP), Riyadh, Saudi Arabia. Materials and Methods: The study reviewed 1521 panoramic radiographs of Saudi and non-Saudi subjects who attended RCsDP clinic from November 2009 to November 2010. The data were analyzed using the Statistical Package for Social Sciences, utilizing Chi-square. Results: Eighteen (1.2%) patients were found to have NSST, comprising twelve males (66.7%), and six females (33.3%). The most common supernumerary teeth (ST) were the pre-molars six cases (33.3%), followed by the mesiodens, five cases (27.8%). The canines and distomolars three cases (16.6%) each respectively, while the least were the lateral incisors and paramolars of the two cases (11.1%) each. Conclusion: Consanguinity appeared to have a role in the development of hyperdontia in Saudi population because 13 cases (72.2%) out of 18 cases had consanguineous parents, while all patients having consanguineous parents had eumorphic ST

Double palatal roots in maxillary second molars: A case report and literature review

A thorough understanding of internal and external anatomy of various teeth is critical for a successful outcome of endodontic therapy. The aims of this paper were (1) to describe the clinical retreatment of a maxillary second molar with two palatal roots and (2) to review the available literature regarding this anatomical variation. A 45-year-old Saudi female presented for non-surgical retreatment of maxillary left second molar. Careful radiographic and clinical examinations revealed the presence of two buccal and two palatal roots each with a single root canal. Anatomical variations can occur in any tooth; therefore, the clinicians should always anticipate the occurrence of these variations and utilize all the available tools to diagnose and manage the

Possible use of calcifying nanoparticles in immature root apex treatment

Introduction: There are reports in the literature, which describe different techniques and materials in the challenging management of thin dentin walls and immature root apex. It has been suggested that calcifying nanoparticles (CNPs) could be used in the management of these conditions. The Hypothesis: Compositionally modified CNPs made into a paste could become efficacious in managing thin dentin walls and immature root apex. Calcium and phosphate ions when mixed with CNPs could form a synthetic nanopaste that clinicians could use to manage thin dentin walls and to get a biological seal for immature root apex. Evaluation of the Hypothesis: CNPs can replicate and could facilitate the aggregations of calcium hydroxyapatite to produce a self-surrounding shell. These characteristics of CNPs could be used through their biomineralization process as initial nidus of calcification for further calcification progression to achieve total biological apical seal. If the hypothesis could be supported by biomineralization behavior of the paste (CNPs, Ca2 + , and PO4− ), a new therapeutic agent would have been added to the armamentarium of endodontists. There is need for more in vivo and in vitro investigations of modified nanopaste to manage these conditions
