alveolar bone anomalies

INTRODUCTION: Cleft Lip and Palate is the most common craniofacial anomaly, and cleft lip and palate repair is widely performed. Alveolar cleft accompanies 75% of cleft lip cases and requires alveolar bone graft (ABG) surgery at mixed dentition age. However, studies on rates of ABG surgery are scarce. OBJECTIVE: This study aims to investigate the low popularity of ABG and orthodontic care among patients with ABG history at Cleft and Craniofacial Centre, Cipto Mangunkusumo Hospital, Jakarta...

Mucopolysaccharidosis VI (MPS VI) is a hereditary lysosomal storage disease caused by the absence of the enzyme arylsulfatase B (ARSB). Craniofacial defects are common in MPS VI patients and manifest as abnormalities of the facial bones, teeth, and temporomandibular joints. Although enzyme replacement therapy (ERT) is the treatment of choice for MPS VI, the effects on the craniofacial and dental structures are still poorly understood. In this study, we used an Arsb-deficient mouse model ( Arsb m/m ) that mimics MPS VI to investigate the effects of ERT on dental and craniofacial structures and compared these results with clinical and radiological observations from three MPS VI patients...

Nutritional restriction during developmental periods impairs organ physiology. Female rats were subjected to protein restriction during pregnancy and lactation to analyze dental and maxillary development. Four exposure groups were considered: normal-protein diet during pregnancy and lactation (NP, 17% casein), low-protein diet during lactation (LP-L, 6% casein), low-protein diet during pregnancy and lactation (LP), and low-protein diet during pregnancy (LP-G). Maxillae from 15-day-old male pups were collected...

In our search for innovative drugs that could improve periodontal treatment outcomes, autophagy and its anomalies represent a potential target for therapeutic intervention. We sought to identify autophagy defects in murine experimental periodontitis and study the effectiveness of P140, a phosphopeptide known to bind HSPA8 and inhibit its chaperone properties, and that corrects autophagy dysfunctions in several autoimmune and inflammatory diseases. Experimental periodontitis was induced by placing silk ligature around mandibular first molars...

Dental ankylosis is a serious condition defined as the process that causes the fusion between the dentin or the cementum of the root and the alveolar bone, with the obliteration of the periodontal ligament becoming progressively replaced by bone tissue. The aim of the study was to determine the prevalence, location, severity, and association of dental ankylosis in primary molars with other dental anomalies such as the agenesis of permanent buds. For this study 150 panoramic x-rays were selected from patients with temporary or mixed dentition, aged six to twelve years old, from a private dentistry office and from the Pediatric Dentistry Department of UMFST in Targu-Mures, Romania...

Background: Singleton-Merten syndrome type 1 (SGMRT1) is a rare autosomal dominant disorder caused by IFIH1 variations with blood vessel calcifications, teeth anomalies, and bone defects. Aim: We aimed to summarize the oral findings in SGMRT1 through a systematic review of the literature and to describe the phenotype of a 10-year-old patient with SGMRT1 diagnosis. Results: A total of 20 patients were described in the literature, in nine articles. Eight IFIH1 mutations were described in 11 families. Delayed eruption, short roots, and premature loss of permanent teeth were the most described features (100%)...

BACKGROUND: Late childhood (8 to 10 years of age) has emerged as a vulnerable period in children with cleft and craniofacial anomalies such that increased interventions during this period are associated with worse long-term patient-reported anxiety and depressive symptoms. These findings suggest that one possible practice change may be to consider changes in timing for surgical treatment algorithms. In this work, the authors investigated outcomes in altering the timing of the most common operation in late childhood for cleft lip and palate patients, alveolar bone grafting...

BACKGROUND: Gastrointestinal lesions, which sometimes develop in Behçet's disease (BD), are referred to as intestinal BD. Although rare, intestinal BD can be accompanied by myelodysplastic syndrome (MDS) with abnormal karyotype trisomy 8, which is refractory to immunosuppressive therapy. Pulmonary alveolar proteinosis is a rare lung complication of BD and MDS. Herein, we present an extremely rare case of intestinal BD presenting with MDS and several chromosomal abnormalities, followed by secondary pulmonary proteinosis...

BACKGROUND: Beta- thalassemia major causes the basic skeletal changes due to ineffective erythropoiesis in suffering patients. The aim of the study was to determine the frequency of maxillo-facial anomalies and the hemoglobin and ferritin levels in patients with beta-thalassemia major compared to the healthy control group. METHODS: The present study was performed on 72 beta- thalassemia major patients and 70 healthy control group in Ahvaz, Southwest Iran, from Jan 2014 to Mar 2015...

To date, there have been no reports of patients showing a Tessier number 7 cleft with unilateral complete cleft lip and palate. Furthermore, no studies have established the sequence, plan, or timing of surgical methods for treating patients presenting the above anomalies simultaneously. We report a case of a Tessier number 7 cleft with unilateral complete cleft lip and palate. Two months after birth, lip adhesion was performed on the unilateral complete cleft lip and total excision was performed on the skin tag...

Van der Woude syndrome (VWS) is a rare syndrome of genetic etiology, commonly occasioned by mutations in the IRF6 gene and that causes disorders in craniofacial development. VWS is characterized by the presence of paramedian fistulas in the lower lip and cleft lip and / or cleft palate. Although some dental phenotypes have been reported in this syndrome, multiple and rare hypodontias were not described. Through this case report, we present a case of Van der Woude Syndrome (VWS) with rare and multiple hypodontia in which clinical data and radiographic exams were evaluated...

OBJECTIVE: The palato-radicular groove (PRG) is caused by a developmental anomaly, genetically determined, whereby an in-folding of the enamel organ and Hertwig's epithelial root sheath occurs. The depth and length of the groove determine the prognosis for the tooth. The interdisciplinary team formulated a treatment plan to save this tooth for this 8-year-old patient. The goal was to prolong the life of the tooth until his growth was completed and a more permanent tooth replacement could be considered if the tooth failed...

OBJECTIVE: To compare the prevalence of dental malformations and agenesis in patients who received or did not receive gingivoperiosteoplasty (GPP). DESIGN: Retrospective cohort study. PATIENTS: Review of patients born January 1, 2000, to December 31, 2007, with unilateral cleft lip and alveolus, with or without clefting of the secondary palate, who received GPP and/or secondary alveolar bone grafting (ABG). Patients were included if they had clinical images and dental radiographs available at ages 5 to 9 and 10 to 12 years...

OBJECTIVE: To assess the effectiveness of the presurgical nasoalveolar molding appliance among infants with unilateral cleft lip and palate. METHODS: In this prospective study, 95 pairs of casts of infants with unilateral cleft lip and palate treated by presurgical nasoalveolar molding were selected at the Children's Hospital 1 at Ho Chi Minh City, Vietnam. The average time of treatment was 3 months. All casts were scanned and measured using 3-dimensional technology before and after treatment...

OBJECTIVE: To evaluate the pulp vitality in teeth adjacent to the cleft area submitted to orthodontic movement into the alveolar graft area in individuals with complete unilateral cleft lip and palate (CUCLP). DESIGN: Cold sensitivity, vertical, and horizontal percussion tests were conducted on the teeth adjacent to the cleft and the contralateral teeth. SETTING: Endodontics Sector in the Hospital for Rehabilitation of Craniofacial Anomalies, University of São Paulo (HRAC/USP)...

THE AIM: Of the work is to develop and substantiate the method of minimally invasive complex orthodontic treatment of patients with constriction and deformation of the upper jaw in the period of permanent bite with the combined use of a bracket system, orthodontic devices for the expansion of the upper jaw and fractional photothermolysis to improve the effectiveness of complex treatment. MATERIALS AND METHODS: The results of complex treatment of patients with the deficiency of the upper jaw in the period of permanent bite are presented...

AIM: To investigate differences in sella turcica size and bridging in children with unilateral cleft lip and palate (UCLP) with or without concomitant dental anomalies. PATIENTS AND METHODS: A cross-sectional study was carried out looking at 56 children with nonsyndromic UCLP. Lateral cephalograms, taken before alveolar bone grafting, were used to assess sella turcica height, width, area, and bridging. Panoramic radiographs were used to evaluate the presence of dental anomalies in the cleft area including agenesis, supernumerary, and peg-shaped lateral incisors...

Thrombocytopenia-absent radius (TAR) syndrome is a congenital malformation in which affected individuals present reductions in the number of platelets, hypoplasia, or absence of radial bone unilaterally or bilaterally. Hematologic, skeletal, cardiac (particularly tetralogy of Fallot and septal-atrial defects), and gastrointestinal anomalies are most commonly associated with TAR syndrome. Skeletal changes result in a higher risk of dental and craniofacial trauma in patients with the syndrome. Thus, it is important for the dentist to be aware of the characteristics of TAR syndrome and its clinical management for better care of these patients...

The aim of the study was to assess the risk of incidence of additional congenital dental anomalies in children with nonsyndromic cleft lip, alveolar and/without palate (CL/P). Hypodontia, hyperdontia and canines impaction was recognized. From patients with CL/P treated at the Clinic of Congenital Facial Deformities in Chair and Department of Jaw Orthopedics Medical University of Lublin, 56 subjects were randomly selected. On the panoramic radiographs taken at the age of 8-12 years, the angle of upper unerupted canines was measured using Westerlund's recommendations...

We report a case of secondary alveolar bone grafting (ABG) without removal of a supernumerary tooth in a patient with unilateral cleft lip and palate. A conical supernumerary tooth located distal to the upper left central incisor within the cleft site was left in situ at the time of ABG. The tooth within the ABG site commenced resorption from both the apical and incisal edges until only minor tooth remnants remained at 22 months. Although external root resorption of teeth neighboring a cleft site has been described previously, this is the first report of almost complete tooth resorption following ABG...
