RESUMO

Dental enamel defects (DED) are lesions that occur due several factors. Proper care is needed to promote their treatment and prevention. The aim of this study was to evaluate the occurrence of DED in permanent teeth of children who used antimicrobial drugs in the first four years of life. This is a crosssectional study carried out in a Primary Health Care (PHC) service, which included children from six to 12 years of age. DED were evaluated by oral examination, and data on the use of antimicrobials in early childhood were collected based on medical records. Data were analyzed with the chi-square test and Fisher's exact test. The sample included 144 children. In relation to DED, 50% (72) and 20.1% (29) presented opacity and hypoplasia, respectively. Amoxicillin was the most frequently prescribed drug, followed by sulfamethoxazole + trimethoprim. Among the children, 78.5% (113) were prescribed antimicrobial drugs at least once during the first 4 years of life, and 55% (79) of them presented some type of DED. There was no statistically significant association between the variables analyzed. In conclusion, there was high prevalence of children with DED, and amoxicillin was the most commonly prescribed antibiotic.

RESUMO

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. In this descriptive study, we aim to chronologically observe tooth eruption and root formation of mouse PFE molars through 3D microCT analyses. SETTING AND SAMPLE POPULATION: Two individuals with PFE were recruited at Showa University. A mouse PFE model was generated by deleting PPR specifically in PTHrP-expressing dental follicle and divided into three groups, PPRfl/fl ;R26RtdTomato/+ (Control), PTHrP-creER;PPRfl/+ ;R26RtdTomato/+ (cHet), and PTHrP-creER;PRRfl/fl ;R26RtdTomato/+ (cKO). MATERIALS AND METHODS: Images from human PFE subjects were acquired by CBCT. All groups of mouse samples were studied at postnatal days 14, 25, 91, and 182 after a tamoxifen pulse at P3, and superimposition of 3D microCT images among three groups was rendered. RESULTS: Mouse and human PFE molars exhibited a similar presentation in the 3D CT analyses. The quantitative analysis in mice demonstrated a statistically significant decrease in the eruption height of cKO first and second molars compared to other groups after postnatal day 25. Additionally, cKO molars demonstrated significantly shortened roots with dilacerations associated with the reduced interradicular bone height. CONCLUSIONS: Mouse PFE molars erupt at a much slower rate compared to normal molars, associated with shortened and dilacerated roots and defective interradicular bones.

RESUMO

A single male domestic shorthair cat that did not complete puberty was reported. At four years of age, it still had primary dentition, testicular hypoplasia, and was relatively small for its age. We hypothesized that the phenotype might have been due to an inherited form of hypogonadotropic hypogonadism (HH). We sequenced the genome of the affected cat and compared the data to 38 genomes from control cats. A search for private variants in 40 candidate genes associated with human HH revealed a single protein-changing variant in the affected cat. It was located in the TAC3 gene encoding tachykinin 3, a precursor protein of the signaling molecule neurokinin B, which is known to play a role in sexual development. TAC3 variants have been reported in human patients with HH. The identified feline variant, TAC3:c.220G>A or p.(Val74Met), affects a moderately conserved region of the precursor protein, 11 residues away from the mature neurokinin B sequence. The affected cat was homozygous for the mutant allele. In a cohort of 171 randomly sampled cats, 169 were homozygous for the wildtype allele and 2 were heterozygous. These data tentatively suggest that the identified TAC3 variant might have caused the suppression of puberty in the affected cat.

RESUMO

OBJECTIVE: The staircase (Sc) pattern enamel microstructure is an expression of an impaired ameloblast function. It has been reported to appear in the neonatal line (NNL), the accentuated stria evincing live birth in deciduous tooth enamel. Our objective was to investigate the prevalence of Sc NNL in deciduous tooth types and its possible association with perinatal circumstances. DESIGN: Sc in the NNL of 88 teeth, a collection derived from a long-term, prospectively followed population cohort, was recorded with linear polarised transmitted light and analysed for tooth type, duration and mode of delivery, and pain medication used during labour. RESULTS: Sc prevalence in the NNL differed highly significantly between tooth types (p < 0.0001). An increase in Sc prevalence was significantly associated with an increased ratio of prenatal to total crown enamel (p < 0.001), when buccal and lingual crown walls were analysed separately. No significant association was found between Sc prevalence and duration or mode of delivery or pain-relieving medication (p = 0.57, p = 0.65, p = 0.58, respectively). CONCLUSION: This research indicates that the NNL location within tooth crown enamel has a strong impact on microstructural changes along the NNL. Considering our results of Sc prevalence, deciduous canines, having the least Sc appearance, could be used in studies that aim to investigate factors associated with NNL width. In addition, Sc prevalence variation in first deciduous molars might enable to investigation of physiological stressors strong enough to cause ameloblast impairment, such as Sc.

RESUMO

Epidemiological investigations of early childhood oral health rely upon the collection of high-quality clinical measures of health and disease. However, ascertainment of valid and accurate clinical measures presents unique challenges among young, preschool-age children. The paper presents a clinical research protocol for the conduct of oral epidemiological examinations among children, implemented in ZOE 2.0, a large-scale population-based genetic epidemiologic study of early childhood caries (ECC). The protocol has been developed for the collection of information on tooth surface-level dental caries experience and tooth-level developmental defects of the enamel in the primary dentition. Dental caries experience is recorded using visual criteria modified from the International Caries Detection and Assessment System (ICDAS), and measurement of developmental defects is based upon the modified Clarkson and O'Mullane Developmental Defects of the Enamel Index. After a dental prophylaxis (toothbrushing among all children and flossing as needed), children's teeth are examined by trained and calibrated examiners in community locations, using portable dental equipment, compressed air, and uniform artificial light and magnification conditions. Data are entered directly onto a computer using a custom Microsoft Access-based data entry application. The ZOE 2.0 clinical protocol has been implemented successfully for the conduct of over 6000 research examinations to date, contributing phenotype data to downstream genomics and other "omics" studies of ECC and DDE, as well as traditional clinical and epidemiologic dental research.

RESUMO

OBJECTIVE: Developmental defects of enamel (DDE) in preterm infants still require clarification and may favour dental caries, lower food intake and greater difficulty with weight-height gain. We evaluated factors associated with DDE in preterm infants. SUBJECTS AND METHODS: In this prospective cohort study, we monitored 54 prematurely born infants from birth to 24 months of age. Trained and calibrated dentists examined the oral cavity of these children to identify and categorize DDE. Information on perinatal variables was collected from the infants' medical records and interviews with their mothers. The data were analysed using Student's t test, a chi-squared test and Pearson's product-moment correlation coefficient. RESULTS: A total of 46.3% of the 54 children presented DDE, which was observed more frequently in the left hemiarch in children born extremely (<28 weeks of gestation) or very preterm (28 to <32 weeks; RR = 2.2; 95% CI 1.3-3.6), with very low birthweight (<1,500 g; RR = 2.0; 95% CI 1.1-3.5), who were admitted to the neonatal intensive care unit (RR = 1.3; 95% CI 1.0-1.7), and who were intubated (RR = 1.6; 95% CI 1.1-2.2). CONCLUSIONS: The high incidence of incisor enamel defects, particularly on the left side, was related to higher risk prematurity and to local trauma from intubation.

RESUMO

La alveólisis es una condición poco frecuente y asintomática. Se produce cuando la raíz del diente primario se vuelve susceptible a la presencia de placa bacteriana y a la formación de cálculos, impidiendo el proceso de cicatrización espontánea de la lesión, causando inflamación e irritación de la mucosa circundante. Las principales causas de la alveólisis son la caries dental y el trauma dentoalveolar. El tratamiento de la alveólisis, generalmente se indica la extracción inmediata. El presente casotrabajo tiene como objetivo describir un reporte de caso de una paciente de género femenino, de 5 años de edad, que presentó alveólisis en el diente primario 51, el cual fue extraído y presentó proceso de cicatrización normal con erupción del diente sucesor 11 sin alteraciones. Cabe al cirujano dentista la búsqueda por informaciones sobre esta patología, saber identificarla y tratarla precozmente, para así mejorar significativamente la calidad de vida de la paciente infantil.

Ocorre quando a raiz do dente torna-se suscetível à presença de biofilme e formação de cálculos, impedindo o processo de cicatrização espontânea da lesão, causando inflamação e irritação da mucosa circundante. As principais causas da alveólise são a cárie dentária e o trauma dentoalveolar. O tratamento da alveólise, geralmente é a exodontia do elemento dentário afetado. O presente trabalho tem como objetivo apresentar um relato de caso de uma criança do gênero feminino, de 5 anos de idade, que apresentou alveólise no elemento dentário 51, o qual foi extraído e apresentou processo de cicatrização normal com irrompimento do elemento 11 sem alterações. Cabe ao cirurgião-dentista a busca pelas informações sobre essa patologia, sabendo identificá-la e trata-la precocemente, para melhorar significativamente a qualidade de vida da criança.


Alveolysis is an asymptomatic and infrequent condition. It occurs when the root of the tooth becomes susceptible to the presence of biofilm and formation of calculi, preventing the process of spontaneous wound healing, causing inflammation and irritation of the surrounding mucosa. The main causes of alveolysis are dental caries and dentoalveolar trauma. In the treatment of alveolysis, immediate exodontia is usually indicated. The present study aims to present a case report of a 5 - year - old female child with alveolysis of primary tooth 51, which was extracted and showed a normal healing process with eruption of successor tooth 11 without alterations. It is up to the dentist to search for information about this pathology, knowing how to identify it and treat it early to significantly improve the child's quality of life.

RESUMO

BACKGROUND: Hereditary enamel defect diseases are regrouped under the name "Amelogenesis Imperfecta" (AIH). Both dentitions are affected. Clinical expression is heterogeneous and varies between patients. Mutations responsible for this multigene disease may alter various genes and the inheritance can be either autosomal dominant or recessive, or X-linked. Until now, no therapeutic consensus has emerged for this rare disease. CASE PRESENTATION: The purpose of this article was to report treatments of AIH patients from childhood to early adulthood. Treatment of three patients of 3, 8 16 years old are described. Each therapeutic option was discussed according to patients' age and type of enamel alteration. Paediatric crowns and resin based bonding must be preferred in primary teeth. In permanent teeth, non-invasive or minimally invasive dentistry should be the first choice in order to follow a therapeutic gradient from the less invasive options to prosthodontic treatments. CONCLUSION: Functional and aesthetic issues require patients to be treated; this clinical care should be provided as early as possible to enable a harmonious growth of the maxillofacial complex and to prevent pain.

RESUMO

OBJECTIVE: The aim of this study was to investigate the characteristics of primary fused teeth (PFT) and their effect on permanent dentition in a group of Turkish children. SUBJECTS AND METHODS: Dental records of 13,450 pediatric patients who attended the Pediatric Dental Clinic in northern Turkey between 2015 and 2017 were reviewed. Forty patients had been diagnosed with PFT and were included in the study. Clinical and radiographic examinations were conducted, and the distribution of PFT was calculated by type, sex, affected jaw, associated dental anomalies, and clinical complications. Data analysis involved descriptive statistics. RESULTS: A total of 50 PFT were detected in the 40 patients. The mean age of patients was 6.7 ± 0.3 years (range 3-10 years). The most common PFT were the mandibular lateral incisors and canines (34, 68%). The most prevalent type of PFT was type III (20, 40%). Of the 40 patients with PFT, 34 (85%) also ex-hibited other dental anomalies such as tooth aplasia, peg-shaped incisors, talon cusps, ectopic eruption, and delayed eruption in both related and unrelated areas. The most common complications of PFT were fusion-related tooth aplasia (n = 26 [76%]) and caries formation in the affected teeth (24 [48%]). CONCLUSION: In this study, PFT were frequently observed in the mandibular anterior region. Caries formation and dental anomalies, especially permanent tooth aplasia, were often encountered in areas where PFT were seen. Hence, parents should be informed about possible dental problems associated with PFT and be encouraged to schedule regular follow-up appointments.

RESUMO

BACKGROUND: This systematic review aims to evaluate the survival of retaining or replacing deciduous teeth in hypodontia patients with a variety of prosthetic tooth replacement options, to evaluate prognostic factors associated with retaining deciduous teeth, and report on patient based outcomes with these treatment modalities. METHODS: MEDLINE, The Cochrane Central Register of Controlled Trials and Science Direct databases were searched (01/1980 - 08/2017) for studies reporting outcomes associated with retaining or replacing deciduous teeth via prosthetic means in adult hypodontia patients. RESULTS: Twenty-one articles were included. The following survival figures were reported; retaining deciduous tooth/teeth (83%-93%), resin-bonded bridgework (59-96.9%) and implants (86-100%). No survival data was reported for fixed or removable partial dentures. Prognostic factors for deciduous tooth survival, quality of life and patient satisfaction data were also reported. CONCLUSION: Within the limits of this review, retaining deciduous teeth have reasonable survival; however, studies beyond the third decade of life are lacking. Dental implants appear to be a highly successful long-term tooth replacement option with high patient satisfaction within this patient group, as have resin-bonded bridgework, albeit over the short to medium term. Tooth replacement options in the form of fixed and removable partial dentures were poorly reported upon.

RESUMO

Objective: To analyze the chronology of first deciduous tooth eruption in children with microcephaly associated with presumed or confirmed Zika virus. Material and Methods: A longitudinal study was developed with 74 children of both sexes. Data on prematurity, gestational age (in weeks), anthropometric characteristics at birth [length (cm), weight (g) and cephalic perimeter (cm)] and dental eruption (chronological age and corrected age for prematurity in months) were collected and presented through descriptive statistics. Data was analyzed using the Statistical Package for Social Sciences. Results: The majority of children were female (54.1%) and 14.9% were born premature. The mean gestational age was 38.2 (± 1.9) weeks, while length, weight and cephalic perimeter at birth were 45.6 (± 3.1) cm, 2750 (± 526.6) and 30 (± 2.3) cm, respectively. The eruption of the first tooth occurred on average at 12.3 (± 3.0) months of chronological age and at 11.1 (± 2.3) months of corrected age. The first erupted teeth were the lower deciduous central incisors (82.4%). The mean age for dental eruption in males was 12.5 months (± 3.0) and in females 12.0 months (± 3.1) among full-term children. For premature infants, the mean corrected age of dental eruption was 11.5 months (± 3.4) for boys and 11 months (± 1.7) for girls. Conclusion: In this group of children with microcephaly, the first tooth to erupt was the lower central incisor around the first year of life. Girls had lower average eruption time when compared to boys in both chronological age and age corrected for prematurity.

RESUMO

OBJECTIVE: Understanding potential problems associated with primary double teeth (PDT) are important to provide prophylactic measures, thereby preventing or minimizing possible complications. The purposes of this study were to investigate the prevalence of PDT in a group of Turkish children and to compare the distribution of the different types of double primary teeth and their relationship to permanent successors. MATERIALS AND METHODS: A total of 17,268 children underwent a clinical examination to determine the presence of PDT. One hundred fifty-two PDT of 128 children were included in this study. All the 128 children with PDT underwent a clinical examination and had photographs taken at the time of the examination. The children underwent a further periapical or panoramic radiographic examination to determine the status of the underlying permanent successors. The PDT was classified according to Aguilo's classification. RESULTS: The prevalence of PDT was 0.74%, with no significant statistical difference between the sexes. PDT was most frequently observed between the mandibular lateral incisors and canines. Of the 152 PDT, 10.7% were Type I, 15.3% were Type II, 26.1% were Type III, and 47.9% were Type IV. Dental anomalies on the succedaneous permanent teeth were diagnosed in 69.4% of the children with affected primary dentition. Aplasia of the permanent lateral incisor was observed most frequently in association with Type I (52.7%) PDT. Caries involvement was observed most frequently in Type III (56.2%) PDT. CONCLUSION: The findings of this study have clinical relevance for the diagnosis of children with PDT. Early clinical and radiographic identification of PDT can help the clinician to evaluate the number and condition of permanent successors and draw up a proper treatment plan.

RESUMO

The present study reports the treatment carried out in a patient with mandibular second premolar agenesis associated with early loss of a deciduous second molar, deep overbite, severe overjet and dentoalveolar bimaxillary protrusion, which led to lip incompetence and a convex facial profile. The main objectives of this treatment were: to eliminate the spaces in mandibular arch, correct overbite, as well as eliminate bimaxillary protrusion and lip incompetence, thus leading to a balanced profile. The case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as part of the requirements to obtain the title of BBO diplomate.

RESUMO

Background: An eruption cyst (EC) is a benign, developmental cyst associated with a primary or permanent tooth. This paper presents 66 ECs in 53 patients who reported to 3 different centers in Turkey between 2014-2015. Material and Methods: 53 patients (31 male, 22 female) with 66 ECs were diagnosed and treated over a 1-year period. The mean age of patients was 5.4 years (minimum 5 months, maximum 11 years). Clinical examination and periapical radiographs were used to establish diagnosis. Age, gender, site, history of trauma and type of treatment were recorded. Results: Of the 66 ECs diagnosed in 53 patients, more than half (56.6%) were located in the maxilla, with the maxillary first primary molars the teeth most commonly associated with ECs (30.3%). Multiple ECs were diagnosed in 13 of the 53 patients. ECs had previously diagnosed in the primary dentition of 2 patients, 3 patients reported a history of trauma to primary teeth. In the majority of patients (46 cases, 86.8%), no treatment was provided, whereas surgical treatment was provided in the remaining 7 cases (13.2%). Conclusions: Eruption cysts are usually asymptomatic and do not require treatment;. however, if the cyst is symptomatic, it should be treated with simple surgical excision (AU)

RESUMO

Down syndrome is one of the most common congenital anomaly. It is most frequently caused by trisomy of chromosome 21. Other causes can be mosaicism and translocation. Such patients are commonly encountered in routine dental practice. This syndrome has wide range of medical and dental abnormalities. This paper presents a unique case of fusion and concrescence of retained primary teeth in a child with Down syndrome. The incidence of such anomalies is quite low in these cases. Thus, a better awareness of such conditions on part of a dental practitioner will aid in the provision of enhanced dental care to these patients.

RESUMO

OBJECTIVE: The objective of this study was to estimate the prevalence of dental anomalies in primary dentition of Indian population. MATERIALS AND METHODS: This cross-sectional study was conducted on 4180 children in the age of 2-6 years. Anomalies were classified based on Kreiborg criteria. The term "double tooth" was used to avoid misinterpretation between gemination. and fusion. Patients having radiographs were also examined for associated dental anomalies in permanent dentition. The occurrence and gender prevalence were evaluated using descriptive statistics. RESULTS: About 95. (2.27%) children exhibited at least one dental anomaly. Thirty.seven children showed 51 missing teeth. (0.88%), mostly in lower right incisors with a statistically significant difference between arches. (P = 0.0056) Nine children. (0.21%) had supernumerary teeth commonly in the right maxilla. Two cases of oligodontia. (0.04%) and talon cusps. (0.04%) and one case of triple tooth. (0.02%) were observed. Forty children. (0.95%) had 43 double teeth mostly in the right mandible with a statistically significant difference between the arches. (P = 0.0105). No significant difference was observed based on gender and arch, but they were statistically significant between the right and left sides. (P = 0.018). Among the children with radiographs available, 45% showed anomalies in the succedaneous dentition. CONCLUSIONS: The prevalence rates of children with double tooth, hypodontia, and hyperdontia in our study are 0.95%, 0.88%, and 0.21%, respectively. The overall prevalence rate of anomalies among boys was higher than girls.
