ENAM gene polymorphisms associated with dental anomalies in individuals with cleft lip and palate

Aim: This study aimed to investigate the occurrence of enamelin gene (ENAM) single nucleotide polymorphisms (SNP) and ENAM polymorphism association with dental anomalies (DA) in individuals with unilateral or bilateral cleft lip and palate (CLP). Methods: Saliva samples were collected from 147 individuals aged between 6 and 15 years-old, both genders, and divided into 4 groups: Group 1 (G1) - CLP and DA; Group 2 (G2) - CLP without DA; Group 3 (G3) - without CLP with DA; Group 4 (G4) - without CLP and DA. The genomic DNA was extracted from saliva samples and the following ENAM SNPs markers were genotyped: rs3796703, rs3796704, rs3796705, rs7671281, rs2609428, and rs35951442. Fisher exact and Pearson's Chi-square tests statistically analyzed the results (α=5%). Results: Individuals without CLP with DA (Group 3 - 19.2%) showed statistically higher prevalence of SNP rs2609428 heterozygotes (p=0.006) than individuals with CLP and DA (Group 1 - 0%). Individuals without CLP (10%) exhibited statistically higher prevalence of mutated heterozygotes/homozygous (p=0.028) than in individuals with CLP (1.3%). Conclusion: SNP rs2609428 marker of ENAM gene may be associated with dental anomalies in individuals without cleft lip and palate

Outcomes of permanent canines on the cleft side after secondary alveolar grafting using different materials in complete unilateral cleft lip and palate

Abstract The prevalence of impaction of the permanent canine on the cleft side (PCCS) ranges from 12-35% after alveolar bone grafting (ABG). PCCSs usually develop above other permanent teeth in the alveolar process, gradually becoming vertical until they reach the occlusal plane. The type of cleft, hypodontia of lateral incisor on the cleft side, slower PCCS root development, and genetic factors are predictors of impaction and/or its ectopic eruption. Objective: To compare the behavior of PCCS in individuals with complete unilateral cleft lip and palate (UCLP) subjected to secondary alveolar grafting (SAG) with different materials. Methodology: This retrospective longitudinal study analyzed 120 individuals undergoing SAG with iliac crest bone, rhBMP-2, and mandibular symphysis. The individuals were selected at a single center and equally divided into three groups. Panoramic radiographs were analyzed by the Dolphin Imaging 11.95 software to measure PCCS angulation and PCCS height from the occlusal plane at two different timepoints. Results: No statistical significance was found between grafting materials (P=0.416). At T1, the PCCS height from the occlusal plane was greater for rhBMP-2 and mandibular symphysis compared to iliac crest bone. The lateral incisor on the cleft side was not related to success or lack of eruption of PCCS (P=0.870). Conclusion: Impaction rates of PCCS were similar for the materials studied. Absence of the lateral incisor on the cleft side did not prevent spontaneous eruption of PCCSs.

Does the rehabilitation treatment predispose the patient with cleft to endodontic treatment?

Aim: to verify the relation between endodontic treatment of teeth adjacent to the cleft area and the rehabilitation of patients with unilateral cleft lip and palate, at the Hospital for Rehabilitation of Craniofacial Anomalies. Methods: the present split-mouth study was composed of 406 individuals with complete unilateral cleft lip and palate who had completed the rehabilitation process in a single tertiary cleft center (55.9% males). The information was collected from the dental history on the patients' records and radiographs. The frequency of endodontic treatment in the upper incisors and canines was calculated for the cleft and non-cleft sides. The comparison between sides was performed by the chi-square test (p <0.05). Results: endodontic treatment was more frequent in teeth adjacent to the cleft than in contralateral teeth. The frequency of endodontic treatment in at least one tooth adjacent to the cleft was 18.97%, and 11.6% on the contralateral side. It was observed that endodontic treatment was necessary in 63.5% of patients who had been submitted to orthodontic treatment, 42.4% of those rehabilitated with fixed partial dentures and 12.0% of patients who underwent dental reshaping of teeth adjacent to the cleft. The treatments performed included vital pulp therapy (46.1%), non-vital pulp therapy (46.8%) and endodontic retreatment (7.1%). Conclusion: in individuals with complete cleft lip and palate, teeth close to the bone defect area and used for rehabilitation treatment presented greater need of endodontic intervention

Objetivo: avaliar, radiograficamente, a prevalência, extensão e severidade da reabsorção dentária em dentes adjacentes à área de fissura após enxerto ósseo alveolar. Métodos: radiografias de 200 indivíduos com fissura unilateral e bilateral, alveolar e palatina, foram analisadas para se investigar a presença de reabsorção dentária relacionada com o enxerto ósseo. No total, 1.315 radiografias foram analisadas (periapical, oclusal e radiografias panorâmicas), obtidas a partir de 200 indivíduos com fissura labiopalatina unilateral e bilateral completa ubmetidos a cirurgia de enxerto, disponíveis a partir dos arquivos da Seção de Radiologia do HRAC-USP. Resultados: entre os 200 indivíduos, 33 tinham reabsorções dentárias externas. Dessas, 15 estavam presentes nas radiografias pré-operatórias e 18 só depois do enxerto ósseo. No geral, 30 reabsorções localizaram- se no terço apical da raiz e 3 no terço cervical; o incisivo central esquerdo foi o mais afetado. Não foram observadas reabsorções dentárias no terço médio da raiz e nenhuma reabsorção afetou mais de um terço. Não existiu diferença estatisticamente significativa entre a idade do paciente durante a cirurgia de enxerto ósseo e a presença de reabsorção dentária externa. Conclusões: a prevalência da reabsorção dentária em dentes adjacentes à área da fissura em indivíduos submetidos a enxerto ósseo foi baixa (16,5%). O terço apical da raiz foi o local mais frequente de reabsorção radicular externa, e não houve reabsorções afetando mais de um terço da raiz. (AU)

Male individuals with Robin Sequence: emerging significant association with ABO and RhD blood group phenotypes

ABSTRACT Background: This study investigated the association of Robin Sequence with ABO and RhD blood group phenotypes. Methods: A retrospective cross-sectional study was performed of a cohort of Robin Sequence patients of the Hospital de Reabilitação de Anomalias Craniofaciais - Universidade de São Paulo (USP), Brazil. The study group was composed of 339 individuals of both genders with Robin Sequence referred for specific treatment. A control group was composed of 1780 individuals without syndromes. The groups were compared using the Pearson' chi-square test (χ 2) with statistical significance being defined for an alpha error of 5% (p-value < 0.05). Results: A comparison of gender found a significant difference for the AB phenotype between groups (p-value = 0.007). Comparing blood type by gender there was no significant difference within the same group (p-value = 0.117 and 0.388 respectively, for Robin Sequence and the control group). When comparing the AB blood type between groups, there was no difference for females (p-value = 0.577), but there was a significant difference for males (p-value = 0.0029). Conclusions: This study showed that the population with Robin Sequence had different patterns related to gender concerning the phenotypic distribution of ABO and RhD blood group phenotypes. Robin Sequence is more common among females. The AB phenotype was significantly higher in males with Robin Sequence than in males of the Control Group. The prevalence of the RhD-negative phenotype is higher in individuals with Robin Sequence. This result suggests a possible association of ABO and RhD phenotypes with Robin Sequence that should be better investigated by molecular studies, as it deserves greater attention.

Evaluation of photobiomodulation therapy associated with guided bone regeneration in critical size defects. In vivo study

Abstract The repair of bone defects raises the interest of investigators in several health specialties. Grafting techniques with bone substitutes and laser therapies have been investigated to replace autogenous bone and accelerate the bone healing process. Objective To evaluate the effect of photobiomodulation therapy (PBMT) associated with guided bone regeneration (GBR) in critical size defects. Material and Methods The study was conducted on 80 male rats (Rattus norvegicus albinus, Wistar) submitted to surgical creation of a critical size defect on the calvaria, divided into eight study groups: group C (control - only blood clot); group M (collagen membrane); group PBMT (photobiomodulation therapy); group AB (autogenous bone); group AB+PBMT; group AB+M; group PBMT+M; group AB+PBMT+M. The animals were killed 30 days postoperatively. After tissue processing, bone regeneration was evaluated by histomorphometric analysis and statistical analyses were performed (Tukey test, p<0.05). Results All groups had greater area of newly formed bone compared to group C (9.96±4.49%). The group PBMT+M (achieved the greater quantity of new bone (64.09±7.62%), followed by groups PBMT (47.67±8.66%), M (47.43±15.73%), AB+PBMT (39.15±16.72%) and AB+PBMT+M (35.82±7.68%). After group C, the groups AB (25.10±16.59%) and AB+M (22.72±13.83%) had the smallest quantities of newly formed bone. The area of remaining particles did not have statistically significant difference between groups AB+M (14.93±8.92%) and AB+PBMT+M (14.76±6.58%). Conclusion The PBMT utilization may be effective for bone repair, when associated with bone regeneration techniques.

The maxillary lateral incisor in the rehabilitation of cleft lip and palate

Abstract Objective This study analyzed the maintenance of lateral incisors in the dental rehabilitation of individuals with cleft lip and palate. Material and Methods The study was conducted on a tertiary craniofacial center and comprised retrospective analysis of panoramic and periapical radiographs of Caucasoid individuals with non-syndromic complete unilateral cleft lip and palate, analyzing all radiographs available on the records of each individual, from the first to the last up to 12 years of age. Overall, 2,826 records were reviewed to achieve a sample of 1,000 individuals. Among these, 487 individuals presented the permanent lateral incisors on both cleft and non-cleft sides, which were included in this study. Results The results were evaluated in percentages and by descriptive statistics. The association between maintenance of the lateral incisor and timing of alveolar bone graft were analyzed by the t test. Among the 487 individuals, 265 had not completed treatment, 62 presented insufficient information, and 44 concluded the treatment elsewhere. Among the remaining 116 individuals, the lateral incisor was extracted from 88 (75.86%) of them on the cleft side (CS) and from 23 (19.83%) people on the non-cleft side (NCS). The age at accomplishment of alveolar bone graft was significantly associated with maintenance of the lateral incisor on the cleft side (p<0.01). Most extractions were indicated because of the inadequate positioning on the CS and for midline correction on the NCS. Rehabilitation was primarily completed by orthodontic movement (53 individuals on the CS and 13 individuals on the NCS). Conclusion In conclusion, the lateral incisor on the cleft side was not maintained in most individuals. Positive relationship was observed between extraction of the lateral incisor and age at accomplishment of the alveolar bone graft, suggesting the need to anticipate the initial radiographic evaluation to enhance its maintenance and reduce the procedures required for rehabilitation.

Sequência de Robin e suas repercussões sobre a microbiota bucal: revisão de literatura / Robin sequence and its repercussions on the oral microbiota: literature review

A cavidade bucal é a principal porta de entrada dos micro-organismos existentes no meio externo para o interior do corpo humano. A sequência de Robin é descrita como uma tríade de anomalias, caracterizada por micrognatia (hipodesenvolvimento mandibular) e glossoptose (deslocamento posterior da língua, que causa obstrução na faringe), com ou sem fissura palatina associada. Diante disso, o objetivo do presente estudo foi realizar uma revisão de literatura enfatizando as características principais e peculiares da microbiota bucal de crianças com sequência de Robin. A dificuldade respiratória, de ingestão de nutrientes, aleitamento materno insuficiente, otites recorrentes, entre outras complicações, ocorrem com frequência em crianças com essa patologia, influenciando a composição da microbiota bucal. A associação da palatoplastia e o uso de antibiótico intensificam as mudanças nessa microbiota. Novas investigações devem ser realizadas, para verificar quais fatores relacionados com a malformação craniofacial, ao tratamento cirúrgico e ao uso de antimicrobianos estariam implicados na alteração da microbiota bucal descrita neste trabalho, bem como suas repercussões clínicas...

Evaluation of fecal microorganisms of children with cleft palate before and after palatoplasty

This study isolated and quantified intestinal bacteria of children with cleft palate before and after palatoplasty. A prospective study was conducted from May 2007 to September 2008 on 18 children with cleft palate, aged one to four years, of both genders, attending a tertiary cleft center in Brazil for palatoplasty, to analyze the effect of surgical palate repair on the concentration of anaerobes Bacteroides sp, Bifidobacterium sp and microaerophiles Lactobacillus sp in feces of infants with cleft palate before and 24 hours after treatment with cefazolin for palatoplasty. There was significant reduction of Lactobacillus sp (p < 0.002), Bacteroides sp (p < 0.001) and Bifidobacterium sp (p = 0.021) after palatoplasty, revealing that surgery and utilization of cefazolin significantly influenced the fecal microbiota comparing collections before and after surgery. However, due to study limitations, it was not possible to conclude that other isolated factors, such as surgical stress, anesthetics and other medications used in palatoplasty might have a significant influence on the microbiota. Considering the important participation of the intestinal microbiota on both local and systemic metabolic and immunological activities of the host, professionals should be attentive to the possible influence of these changes in patients submitted to cleft repair.

Programmatic actions in oral health: coping with social inequities

Inequities are health imbalances that are avoidable, unfair and unnecessary. Studies on health inequities address the need for emergency care related to oral-dental lesions from external causes, toothache or prevalence of oral lesions, taking into account the differences between individuals and/or populations in terms of risk conditions to acquiring disease or access to health services. Inequities may be caused by the health service itself, because diseases affect socially deprived individuals more frequently and severely, especially because of multimorbidity. In the current Brazilian public health situation, programmatic actions are based on technological knowledge, especially epidemiology, focused on specific pathologies or disease risk groups, and relate closely to the organization of programmed demand. Moreover, programmatic actions should strategically use technological devices, without disregarding technical and policy flexibility, and should be closely related to inter-subjectivity and ethics, in order to develop emancipating capabilities. An action having this structure could make it easier to achieve Universality, Equity and Integrality.

Mechanisms and clinical management of pain

Pain is an unpleasant, sensitive and emotional experience associated with or described in terms of tissue lesion, and may be acute or chronic. It may also be classified as nociceptive, neuropathic or psychogenic. Nociceptive pain involves the transformation of environmental stimuli into action potentials carried to the central nervous system, where they are modulated and integrated up to final interpretation in the cerebral cortex. Neuropathic pain may arise as a consequence of the direct lesion of axons, or of an increase in the production of neurotrophic factors. Chronic pain is always associated with anxiety and some degree of depression. Drug therapy should be selected according to its efficacy; nonetheless, the professional should also consider the tolerability and adverse effects that may occur, for example, in elderly individuals. It is necessary to emphasize the safety-considering the possibility of drug interactions-and define the posology to promote better adherence. However, the treatment of neuropathic pain should not be limited to the use of analgesic drugs, which are just one among several options enabling patients to participate in bio-psycho-social rehabilitation programs.

Comparison of periodontal parameters in individuals with syndromic craniosynostosis

Craniosynostosis syndromes are characterized by premature closure of one or more cranial sutures, associated with other malformations, the most frequent of which are the Crouzon and Apert syndromes. Few studies in the literature have addressed the oral health of these individuals. The purpose of this study was to compare the periodontal status of individuals with Apert, Crouzon, Pfeiffer and Saethre-Chotzen syndromes before toothbrushing and compare the efficiency of plaque removal before and after mechanical toothbrushing. The probing depth, plaque index (according to Lõe and O'Leary), clinical attachment level, gingival index (according to Silness and Lõe) and amount of keratinized mucosa were evaluated before toothbrushing, and the O'Leary plaque index was assessed before and immediately after toothbrushing, on the same day, in 27 individuals aged 11 to 36 years. There was statistically significant difference in the mean probing depth and clinical attachment level among regions (p=0.00; p=0.01, respectively). The gingival index did not reveal statistically significant differences. With regard to the plaque index, the left region exhibited higher plaque index values than the right and anterior regions. No significant results were found in the analysis of keratinized mucosa. Comparison of the O'Leary plaque index before and after toothbrushing revealed statistically significant difference for all syndromes except for the Pfeiffer syndrome (p<0.05). In conclusion, there was no difference in the periodontal status among individuals with syndromic craniosynostosis. The posterior region was more affected than the anterior region as to the presence of plaque, loss of insertion and probing depth. Individuals with Pfeiffer syndrome exhibited greater toothbrushing efficiency than individuals with the other craniosynostosis syndromes.

Oral findings in patients with Apert Syndrome

INTRODUCTION: The Apert syndrome is a rare disorder of autosomal dominant inheritance caused by mutations in the FGFR2 gene at locus 10q26; patients with this syndrome present severe syndactyly, exophthalmia, ocular hypertelorism and hypoplastic midface with Class III malocclusion, besides systemic alterations. Most investigations available on the Apert syndrome address the genetic aspect or surgical management, with little emphasis on the oral aspects. OBJECTIVE: to investigate the oral findings, including dental anomalies, ectopic eruption of the maxillary permanent first molars and soft tissue alterations, in subjects with Apert syndrome. MATERIALS AND METHODS: clinical and radiographic examination of nine patients with Apert syndrome, aged 6 to 15 years, not previously submitted to orthodontic or orthognathic treatment. RESULTS: dental anomalies were present in all patients, with one to eight anomalies per individual. The most frequent anomalies were tooth agenesis, mainly affecting maxillary canines, and enamel opacities (44.4 percent for both). Ectopic eruption of maxillary first molars was found in 33.3 percent of patients; lateral palatal swellings were observed in 88.8 percent of patients. CONCLUSIONS: The occurrence of typical lateral palatal swellings agrees with the literature. The high prevalence of dental anomalies and ectopic eruption may suggest a possible etiologic relationship with the syndrome.

INTRODUÇÃO: A síndrome de Apert é um distúrbio raro de herança autossômica dominante causado por mutações no lócus 10q26 do gene FGFR2; pacientes com esta síndrome apresentam sindactilia severa, exoftalmia, hiperteleorbitismo e hipoplasia da face média com má oclusão de Classe III, além de alterações sistêmicas. A maior parte dos estudos disponíveis sobre a síndrome de Apert aborda o aspecto genético ou manejo cirúrgico, com pouca ênfase nos aspectos bucais. OBJETIVO: investigar os achados bucais, incluindo anomalias dentárias, irrupção ectópica dos primeiros molares permanentes superiores e alterações de tecido mole, em indivíduos com síndrome de Apert. MATERIAIS E MÉTODOS: exame clínico e radiográfico de nove pacientes com síndrome de Apert, de 6 a 15 anos de idade, não anteriormente submetidos a tratamento ortodôntico ou ortognático. RESULTADOS: anomalias dentárias estavam presentes em todos os pacientes, com uma a oito anomalias por indivíduo. As anomalias mais freqüentes foram agenesia dentária, principalmente afetando os caninos superiores, e opacidades de esmalte (44,4 por cento para ambos). Foi observada irrupção ectópica dos primeiros molares superiores em 33,3 por cento dos pacientes; foram observados aumentos volumétricos laterais da mucosa palatina em 88,8 por cento dos pacientes. CONCLUSÕES: a ocorrência de aumentos volumétricos laterais típicos da mucosa palatina concorda com a literatura. A alta prevalência de anomalias dentárias e irrupção ectópica pode sugerir uma possível relação etiológica com a síndrome.

Pattern of disocclusion in patients with complete cleft lip and palate

OBJECTIVE: to analyze the pattern of disocclusion during excursive mandibular movements and presence or absence of occlusal interferences and occlusal pathologies (gingival recession and abfraction). METHOD: examination of 120 individuals divided into two groups, as follows: Group 1 - 90 patients with complete cleft lip and palate (study group), subdivided into 30 patients with complete left unilateral cleft lip and palate, 30 patients with complete right unilateral cleft lip and palate and 30 patients with complete bilateral cleft lip and palate; Group 2 - 30 individuals without clefts (control group). RESULTS: 58.8 percent of patients in Group 1 presented unilateral or bilateral canine guidance, 26.6 percent presented unilateral or bilateral group function and 54.4 percent presented lateral movements through the posterior teeth. Regarding protrusive movements, 80 percent presented anterior guidance and 20 percent presented posterior guidance. In Group 2, 69.6 percent of individuals presented unilateral or bilateral canine guidance, 43.2 percent presented unilateral or bilateral group function and only 13.3 percent presented lateral movements through the posterior teeth; 3.4 percent presented protrusion through the posterior teeth. CONCLUSIONS: there was no difference in the pattern of disocclusion between subgroups of patients with clefts. Group 2 presented predominance of bilateral group function, whereas Group 1 presented a higher prevalence of posterior guidance during lateral movements. Protrusion occurred primarily through anterior guidance in Group 2 and through the posterior teeth in Group 1. There was high prevalence of occlusal interferences at the molar area for both groups, yet with no correlation with occlusal pathologies (recession and abfraction).

OBJETIVO: avaliar o padrão de desoclusão apresentado nos movimentos excursivos mandibulares e a presença ou não de interferências oclusais e patologias relacionadas à oclusão (recessão gengival e abfração). MÉTODO: exame de 120 indivíduos, divididos em 2 grupos: Grupo 1 - 90 pacientes com fissura completa de lábio e palato, subdivididos em 30 pacientes com fissura completa de lábio e palato unilateral esquerda, 30 pacientes com fissura completa de lábio e palato unilateral direita e 30 com fissura completa de lábio e palato bilateral; e Grupo 2 - 30 indivíduos sem fissuras (grupo controle). RESULTADOS: 58,8 por cento do Grupo 1 apresentaram guia canina uni ou bilateralmente, 26,6 por cento apresentaram desoclusão com função em grupo uni ou bilateral e 54,4 por cento realizaram estes movimentos laterais através dos dentes posteriores; 80 por cento dos pacientes do Grupo 1 realizava protrusão pelos dentes anteriores e 20 por cento pelos posteriores. Para o Grupo 2, guia canina uni ou bilateral foi observada em 69,6 por cento dos indivíduos, 43,2 por cento apresentaram função em grupo uni ou bilateral e somente 13,3 por cento realizaram os movimentos laterais pelos dentes posteriores. Apenas 3,4 por cento dos indivíduos do Grupo 2 apresentaram protrusão pelos dentes posteriores. CONCLUSÕES: não houve diferença estatisticamente significativa no padrão de desoclusão entre os subgrupos de pacientes com fissuras. O Grupo 2 apresentou predominância de função em grupo bilateral, enquanto o Grupo 1 apresentou maior prevalência de guia posterior durante os movimentos laterais. A protrusão ocorreu principalmente por guia anterior no Grupo 2 e pelos dentes posteriores no Grupo 1. Houve alta prevalência de interferências oclusais na região de molares para ambos os grupos, entretanto sem correlação com patologias oclusais (recessão e abfração).

Tendência familial das fissuras labio-palatais / Familial tendency of oral clefts

Este estudo visou investigar a porcentagem de pacientes com fissuras que relatam a existência de casos anteriores de indivíduos com fissuras ou outras anomalias congênitas na família. Foram entrevistados 803 pacientes com fissura de lábio e/ou palato, com ou sem más formações adicionais e sem síndromes reconhecíveis; as informações foram analisadas em porcentagens e médias. Uma porcentagem significante da amostra (32,3 por cento), apresentou um ou mais casos de indivíduos com anomalias na família, com uma influência notável da presença de irmãos com fissuras e parentes com tipos mais severos de fissuras. Os resultados sugerem a presença de herança entre os prováveis fatores etiológicos. Todos os profissionais da saúde devem estar cientes deste fato para possibilitar o fornecimento de informação e aconselhamento
