Dental dilaceration

BACKGROUND/AIM: Pediatric mandibular distal fractures present unique treatment challenges which are usually managed with open reduction and internal fixation (ORIF) with the risk of developing tooth bud injuries. Conservative management through maxillomandibular fixation (MMF) with orthodontic bracket-elastic as an out-patient department (OPD) service has been used for these fractures presenting with derangement of occlusion. The aim of this study was to retrospectively analyze MMF with orthodontic bracket-elastic as a treatment method and its outcome for management of pediatric mandibular distal fractures...

AIM AND OBJECTIVE: The aim and objective of this study was to review the literature to analyze the prevalence of developmental dental anomalies regarding shape in India. BACKGROUND: Although there have been several studies investigating the prevalence of individual dental anomalies related to shape, only a few studies considered all subtypes and their distribution among genders, especially in India. RESULTS: An electronic search was made in the PUBMED database to review prevalence-based data on developmental dental anomalies related to shape in India up to December 2018...

Simultaneous presentation of tuberculosis (TB) and lymphoma in a young child is indeed a very rare entity. Malignancy such as Hodgkin's disease (HD) most commonly causes suppression of the cell-mediated immunity, which makes the individual, especially children, more prone to tuberculous infection. One of the non-life threatening complications in these young cancer survivors is the associated dental anomalies. These can seriously impair the quality of life of teenagers and young adults. Higher incidence of caries, discoloration of teeth or even early loss of teeth requiring dental prosthesis, can be associated with the use of cytostatic drugs...

OBJECTIVES: Primary failure of eruption (PFE) is a genetic disorder exhibiting the cessation of tooth eruption. Loss-of-function mutations in parathyroid hormone (PTH)/parathyroid hormone-related peptide (PTHrP) receptor (PTH/PTHrP receptor, PPR) were reported as the underlying cause of this disorder in humans. We showed in a PFE mouse model that PTHrP-PPR signaling is responsible for normal dental follicle cell differentiation and tooth eruption. However, the mechanism underlying the eruption defect in PFE remains undefined...

Molar-incisor malformation (MIM) is a recently defined dental abnormality of molar root and incisors, and introduced as one of the causes of periapical and periodontal abscess. The purpose of this study was to investigate the clinical and radiological features of MIM, with special emphasis on various medical history. A total of 38 patients with MIM were included in this study. Radiographic features and clinical data, including medical history, chief complaint, associated complications, treatment, and prognosis, were retrospectively investigated...

Traumatic dental injuries are highly prevalent among preschool children. When occurring at a very young age (prior to the eruption of the primary teeth), such trauma can disturb the normal development of the permanent dentition and, more rarely, affect the primary dentition. This report describes a case of a patient who suffered dentoalveolar trauma at six months of age that caused rare developmental problems in the primary dentition, such as impaction, dilacerations, hypoplasia, and odontoma. Imaging revealed that alterations also occurred in the permanent dentition...

Statement of the Problem: Many studies have explored the prevalence of dental anomalies, with conflicting results, possibly attributed to differences in the ethnicities of the populations evaluated. Purpose: The aim of this study was to investigate the prevalence of dental anomalies, using panoramic images, in an Iranian population. Materials and Method: In this cross-sectional study, panoramic radiographs of patients aged 18 years or more, between 2015 and 2017 from three private clinics in Babol and Sari, were evaluated for presence or absence of anomalies (tooth shape, number, structure, and position)...

(1) Background: Oculo-facio-cardio-dental (OFCD) syndrome is a rare pathological condition with an X-linked dominant trait that only occurs in females; no males are born with OFCD syndrome. This syndrome is characterized by congenital cataracts with secondary glaucoma ocular defects, ventricular and atrial septal defects, or mitral valve prolapses. Facial traits are a long narrow face and a high nasal bridge with a bifid nasal tip. Dental anomalies include radiculomegaly, oligodontia, root dilacerations, malocclusion, and delayed eruption...

BACKGROUND: The aim of this study was to record and analyze all DDAs associated to dilacerated teeth in patients attending the clinics of the Postgraduate Division, Facultad de Odontología, UNAM in Mexico City. MATERIAL AND METHODS: Orthopantomograms from all patients seeking for stomatological attention in our institution were reviewed and those cases of dilaceration were separated. Age, gender, diagnosis, location, involved teeth and associated DDAs were recorded and analyzed...

OBJECTIVE: The objective was to investigate dental phenotypes in individuals with non-syndromic Pierre Robin Sequence (ns-PRS) and compare the prevalence of these phenotypes with subjects with non-syndromic cleft palate (ns-CP) and a control group with subjects without any craniofacial anomalies. METHODS: A total of 760 panoramic radiographs of 330 individuals (110 with ns-PRS; 110 with ns-CP and 110 without any malformations) were digitized and evaluated regarding the diagnosis of taurodontism, tooth agenesis, root dilaceration and tooth transposition...

The Iberian lynx is an endangered felid that has been subject to an intensive ongoing conservation program in an attempt to save it from extinction. Identification of dental pathologies could play an important role in the survival of this endangered species. The objective of this study is to evaluate the dental pathologies (congenital, developmental, and traumatic abnormalities) of this species of felid. Skulls of 88 adult specimens of the Iberian lynx ( Lynx pardinus) from the Doñana Biological Station [Estación Biológica de Doñana-Consejo Superior de Investigaciones Científicas] (EBD-CSIC), Seville, Spain, were examined macroscopically, and full-mouth dental radiographs of all specimens were performed...

BACKGROUND/AIMS: Dental trauma to the predecessor teeth can cause crown and root dilacerations to the successor teeth, which can interfere with the normal development of permanent teeth. The aims of this study were to verify the types of trauma more frequent to the predecessor teeth that cause dilaceration to their successor teeth, to determine the frequency of crown and root dilacerations in permanent incisors, taking into account the child's age at the time of trauma, and to describe the types of treatment performed...

INTRODUCTION: Tooth dilacerations are dental anomalies characterized by an abrupt deviation in the longitudinal axis of a tooth. They may occur either in the crown, between the crown and root, or in the root. Although not so common, impacted maxillary incisors exhibiting root dilaceration pose a diagnostic and treatment challenge to the clinician. DESCRIPTION: This case report describes the management of a horizontally impacted and dilacerated maxillary central incisor in a 12-year-old girl...

Traumatic dental injuries in primary dentition present risk of sequelae in the permanent dentition. In this case report, we describe the management and long term follow-up of sequelae affecting permanent central incisor due to prior intrusive luxation and subluxation of the corresponding primary tooth. A 5-year-boy was referred for treatment, with history of fall by the age of 21 months, which caused subluxation of the primary maxillary right and left central incisors, and intrusion of the maxillary right lateral incisor...
