Pre-operative use of dexamethasone does not reduce incidence or intensity of bleaching-induced tooth sensitivity. A triple-blind, parallel-design, randomized clinical trial.

OBJECTIVES: This study evaluated the effect of the administration of pre-operative dexamethasone on tooth sensitivity stemming from in-office bleaching. MATERIALS AND METHODS: A triple-blind, parallel-design, randomized clinical trial was conducted on 70 volunteers who received dexamethasone or placebo capsules. The drugs were administered in a protocol of three daily 8-mg doses of the drug, starting 48 h before the in-office bleaching treatment. Two bleaching sessions with 37.5% hydrogen peroxide gel were performed with a 1-week interval. Tooth sensitivity (TS) was recorded on visual analog scales (VAS) and numeric rating scales (NRS) in different periods up to 48 h after bleaching. The color evaluations were also performed. The absolute risk of TS and its intensity were evaluated by using Fisher's exact test. Comparisons of the TS intensity (NRS and VAS data) were performed by using the Mann-Whitney U test and a two-way repeated measures ANOVA and Tukey's test, respectively. RESULTS: In both groups, a high risk of TS (Dexa 80% x Placebo 94%) was detected. No significant difference was observed in terms of TS intensity. A whitening of approximately 3 shade guide units of the VITA Classical was detected in both groups, which were statistically similar. CONCLUSIONS: It was concluded that the administration pre-operatively of dexamethasone, in the proposed protocol, does not reduce the incidence or intensity of bleaching-induced tooth sensitivity. CLINICAL RELEVANCE: The use of dexamethasone drug before in-office bleaching treatment does not reduce incidence or intensity of tooth sensitivity. CLINICAL TRIAL REGISTRATION NUMBER: NCT02956070.

Can the Enterococcus faecalis identified in the root canals of primary teeth be a cause of failure of endodontic treatment?

OBJECTIVE: This study investigated the presence of Enterococcus faecalis in primary teeth with primary root canal infections and related to the possible failure of pulpectomy outcome after 36 months. MATERIAL AND METHODS: Root canal samples were obtained from 25 out of 244 patients using the sterile paper cone method. The identification of E. faecalis was done with culture and molecular tests using species-specific 16S rRNA gene-based polymerase chain reaction (PCR). After 36 months, the pulpectomy outcome was evaluated. RESULTS: Enterococcus faecalis was found in five (20%) samples, and dental caries were the cause of primary infection in all of them. Pulpectomy outcome was evaluated only in teeth that completed the entire clinical protocol and were followed up to 36 months (n = 8). From these, 75% (n = 6) were successful and 25% (n = 2) failed. E. faecalis was present in 50% of both successful and failed cases. CONCLUSIONS: Enterococcus faecalis was not related to the failure of endodontic treatment of primary teeth.

Does Smear Layer Removal Influence Root Canal Therapy Outcome? A Systematic Review.

OBJECTIVE: The aim of this systematic review was to determine whether the smear layer (SL) removal procedure influences the outcome of root canal treatment. STUDY DESIGN: We performed a search on Pubmed, Scopus, ISI Web of Science, Cochrane Library, Lilacs and SIGLE. We included randomized controlled clinical trials (RCT), with clinical and radiographic outcomes, conducted on subjects who had undergone root canal therapy. The protocol differed only in the SL removal or maintenance procedure. We evaluated the papers for risk of bias according to the Cochrane assessment tool. RESULTS: A total of 1,983 articles were found, after removal of duplicates, 892 remained. We included two studies in this review. One study revealed a low risk of bias and a high success rate for the SL removal group compared to the non SL removal group (P = 0.04), while the other study had a high risk of bias and found no difference between the SL removal and non SL removal groups (P = 1.00). CONCLUSION: We concluded that the SL removal for root canal treatment of primary teeth with initial clinical signs and symptoms or pulpal necrotic status, could benefit the outcome, although further RCT should be performed to achieve evidence.

Can composite packaging and selective enamel etching affect the clinical behavior of bulk-fill composite resin in posterior restorations? 24-month results of a randomized clinical trial.

OBJECTIVES: This is a double-blind, split-mouth, randomized clinical study that aims to evaluate the influence of bulk-fill composite packaging presented in syringes (BSy) and capsules (BCa), and the effect of selective enamel etching (SEE) on the clinical performance of class I and II bulk-fill resin composite restorations after 24 months. METHODOLOGY: A total of 295 class I or class II restorations were performed on 70 patients. One universal adhesive was applied in all restorations. SEE was used in 148 restorations and self-etching mode (SET) in 147 restorations. After the adhesive application, cavities were restored with Filtek Bulk-fill Posterior Restorative in syringes (BSy), Filtek One Bulk-fill in capsules (BCa), or Filtek Supreme Ultra in syringes with the incremental technique (In). All restorations were evaluated using the FDI criteria after one week and after six, 12, and 24 months. Kaplan-Meier survival analysis and Pearson's Chi-square test were used (α=0.05) for statistical analysis. RESULTS: After 24 months, 62 patients were evaluated and four restorations were lost due to fracture (one for SEEBSy, two for SEEIn, and one for SETIn). No significant differences in the fracture and retention rate were found between groups (p>0.05). SEE showed significantly fewer marginal adaptation defects than SET (p<0.05). BCa and BSy groups showed fewer marginal discrepancies compared to In (p<0.05). Restorations performed with BCa showed less color mismatch than BSy or In (p<0.05). CONCLUSION: Although all restorations exhibited satisfactory clinical performance after 24 months of clinical service, the clinical behavior of class I and II restorations' improved when performed with a bulk-fill composite in capsules, mainly when associated with a universal adhesive applied with SEE.

The influence of smear layer removal on primary tooth pulpectomy outcome: a 24-month, double-blind, randomized, and controlled clinical trial evaluation.

BACKGROUND: The effect of smear layer (SL) removal on primary tooth pulpectomy outcome has not been well elucidated. AIM: To determine the effect of SL removal on primary tooth pulpectomy outcome. METHODS: This is a double-blind, randomized, and controlled clinical trial. Forty-eight patients were randomly divided into SL removal (G1 = 40 teeth) or smear layer nonremoval (G2 = 42 teeth) groups. Following the chemomechanical preparation with K-files and 2.5% sodium hypochlorite (NaOCl), teeth were irrigated with either 6% citric acid and 0.9% physiologic solution (G1) or only 0.9% physiologic solution (G2). Camphorated paramonochlorophenol was used as intracanal medication. At the second appointment, 1 week after, root canals were filled with zinc oxide-eugenol paste. Clinical and radiographical baseline criteria were stipulated equally for both groups. RESULTS: The success rate (G1 = 91.2%; G2 = 70.0%) was statistically different (P = 0.04) between the groups. In G2, the outcome was affected significantly by pulpal necrosis (P = 0.02), pre-operatory symptoms (P = 0.02), and periapical/inter-radicular radiolucency (P = 0.04). CONCLUSION: The pulpectomy outcome was improved by smear layer removal. The outcome for teeth with pulpal necrosis, pre-operatory symptoms, or periapical/inter-radicular radiolucency was significantly improved by removal of the smear layer.

Long-term outcomes of primary tooth pulpectomy with and without smear layer removal: a randomized split-mouth clinical trial.

PURPOSE: The aim of this study was to evaluate, via clinical and radiographic assessment, pulpectomy outcomes performed on primary anterior teeth both with and without a citric acid solution to enhance smear layer removal. METHODS: Patients with a matched pair of primary incisors (split-mouth design) with irreversible pulp changes were selected. A total of 36 teeth (18 children) received pulpectomies and were followed for 36 months. Pulpectomies were performed using sodium hypochlorite and saline solution as canal irrigants; during the last irrigation, the tooth was randomly selected to receive ( Group 1) or not receive (Group 2) the citric acid solution for smear layer removal. The roots were filled with ZOE paste. RESULTS: Overall pulpectomy success was 90.6%. Cases with smear layer removal were successful 82.3% of the time; those without smear layer removal, 88.2%, and there were no statistical differences (P=1.00). CONCLUSION: Pulpectomy with smear layer removal in primary incisors exhibited, after 36 months, a high success rate; however, comparable results were obtained when the smear layer was not removed.

Ectopic eruption of permanent incisors after predecessor pulpectomy: five cases.

Pulpectomy in primary teeth is a common technique that preserves teeth in the oral environment and maintains or recovers periapical tissues to a healthy condition. This article describes the ectopic eruption of permanent incisors whose primary predecessors underwent pulpectomy using ZOE filler paste. In a group of 135 teeth that received pulpectomy therapy due to caries, 10 primary maxillary incisors had overretention and were followed for at least 3.5 years (mean time of 4.2 years), both clinically and radiographically, until the permanent teeth erupted. The proposed treatment included extraction of the overretained primary incisors based on permanent successor eruption chronology and contralateral eruption. Seven permanent teeth erupted ectopically. Autocorrection of the permanent tooth positions was observed in five cases. It can be concluded that periodic clinical and radiographic assessments are essential to verify radicular and filling paste resorptions and to avoid overretention and any subsequent malocclusion.

Iodoform Vs Calcium Hydroxide/Zinc Oxide based pastes: 12-month findings of a Randomized Controlled Trial.

This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1) - iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2) - Calen®/ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen®/ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

Clinical time and postoperative sensitivity after use of bulk-fill (syringe and capsule) vs. incremental filling composites: a randomized clinical trial.

The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or capsules). A total of 295 posterior restorations were placed according to the following groups: SETB - self-etch/bulk-fill in syringe; SETC - self-etch/bulk-fill in capsules; SETI - self-etch/incremental; SEEB - selective enamel-etching/bulk-fill in syringe; SEEC - selective enamel-etching/bulk-fill in capsules; and SEEI - selective enamel-etching/incremental. Clinical time was assessed by a reason (s/mm3) between the total volume of resin inserted and the total time required to perform the restorations. Postoperative sensitivity was evaluated using two scales (Numeric Rating Scale and Visual Analogue Scale). Mean clinical time results, analyzed by Wald's Chi-square, showed significant statistical differences among all groups (p<0.001), indicating that the restorative strategy affected the time required for the restoration. A generalized estimating equation model statistical analysis, performed to compare postoperative sensitivity, showed that neither the restorative technique, the adhesive strategy nor the presentation mode of the bulk-fill composite affected the overall risk of postoperative sensitivity (4.06 [2.22-6.81]). The use of bulk-fill composite, presented in capsules or syringes, is less time consuming and does not increase the risk or intensity of postoperative sensitivity relative to the traditional incremental technique.

Pediatric bitewing film holder: preschoolers' acceptance and radiographs' diagnostic quality.

PURPOSE: The purpose of this study was to evaluate a modified bitewing film holder based on preschoolers' acceptance and the diagnostic quality of radiographic images. METHODS: Sixty-six 3- to 5-year-old children were radiographed with the modified device. Acceptance was assessed according to their behavior during the radiographic examination and to their perception of the procedure. In only the 4- and 5-year-olds, the children's perception was assessed using a faces scale. Evaluation of the images' diagnostic quality for each quadrant (considering pairs of radiographs) was based on anatomic structures usually present on bitewing radiographs. RESULTS: During radiographic examination, 73% of the children were cooperative. As to the patients' perceptions (N = 43), 74% showed satisfaction with the radiographic examination. The diagnostic quality of radiographic images (N = 66) was adequate in more than 90% of the cases for all evaluated parameters, except for the visualization of alveolar bone crests (54%) and the absence of proximal overlapping (86%). CONCLUSIONS: The modified bitewing film holder produced adequate radiographs for almost all parameters and was well accepted by preschoolers.

Pulpectomies with Iodoform Versus Calcium Hydroxide-Based Paste: A Preliminary Randomised Controlled Clinical Trial

ABSTRACT Objective: To compare clinical and radiographical pulpectomy outcomes in primary teeth filled with different pastes. Material and Methods: The sample included thirty-eight teeth indicated for pulpectomy due to irreversible pulp inflammation or necrosis from thirty patients (2 to 9 years old). The first appointment comprised chemomechanical preparation (2.5% sodium hypochlorite), smear layer removal (6% citric acid), intracanal dressing and temporary restoration. Seven days later, teeth were randomly assigned to filling with iodoform (IP) or calcium hydroxide with zinc oxide (CHZO) based pastes and temporarily restored. Final restoration (composite resin) occurred at the 3rd appointment. Data from baseline, 6 and 12 months were analysed using descriptive and inferential statistics (p≤0.05). Results: The overall frequency of success was 63.6% (n=21), with no significant difference between groups (IP=62.5% n=10; CHZO=64.7% n=11, p=0.59). Multiradicular teeth, overfilled canals and teeth whose coronal restoration have been lost were significantly associated with failure (p=0.01, p=0.04 and p<0.001, respectively). Conclusion: After 12 months, both pastes showed similar outcomes and can be used as good options for pulpectomies in primary teeth. Moreover, tooth location, extent of the root canal filling, and integrity of final restoration during the follow-up influenced the outcome of pulpectomies.

Protocolo de pulpectomia para dentes decíduos: um guia clínico e prático baseado em evidências científicas / Pulpectomy protocol for primary teeth: a clinical and practical guide based on scientific evidence

O procedimento de pulpectomia em dentes decíduos consiste na remoção total do tecido pulpar com inflamação irreversível ou com necrose, preparo químicomecânico e obturação com material reabsorvível, com o intuito de manter o dente o maior tempo possível na cavidade bucal, devolvendo função e saúde para o paciente infantil. Existem vários protocolos descritos na literatura, no entanto, não há consenso entre eles e poucos possuem acesso livre. Sendo assim, observa-se carência de um guia clínico e prático para nortear o cirurgião-dentista na realização desse procedimento durante o atendimento odontopediátrico. Portanto, o intuito deste trabalho é apresentar aos clínicos um protocolo de pulpectomia com altas frequências de sucesso clínico e radiográfico, baseado em evidências científicas, desenvolvido e aplicado pelo Grupo de Pesquisa de Endodontia em Odontopediatria da Universidade Federal do Rio de Janeiro (GEDOPED-UFRJ). O presente protocolo contempla indicações, contraindicações, tática operatória, materiais necessários e orientações para acompanhamento. Com esta publicação de maneira gratuita, de acesso livre e no idioma dominante do país, espera-se ampliar o alcance de odontopediatras e clínicos gerais que atendem crianças a um tratamento eficaz.

Pulpectomy in primary teeth consists of the complete removal of the irreversibly affected pulp or necrotic pulp tissue, chemical-mechanical preparation of the root dentin and filling root canals with a resorbable material, to keep the tooth as long as possible in the oral cavity, restoring function and health. There are several pulpectomy protocols described in the literature, however, there is no consensus among them and only few of them are open access. Therefore, there is a lack of clinical and practical guides to the practitioner in performing this procedure during pediatric dental care. The aim of this article is to present a clinically and radiographically successful pulpectomy protocol, based on scientific evidence, developed, and applied by the Research Group on Endodontics in Pediatric Dentistry at the Universidade Federal do Rio de Janeiro. This protocol includes indications, contraindications, operative techniques, materials, and guidelines for follow-up appointments. With this open access publication in Portuguese, we hope to disseminate an effective treatment and expand the outreach of a pulpectomy technique protocol to pediatric dentists and clinicians who treat children.

Mirror image: an unusual case of prolonged tooth retention in twins

Introduction: Studies of twins are important because environmental and genetic factors seem to be related to the phenotypic alterations. Objective: This paper presents a unique case of monozygotic twins with mirror image of a retained primary central incisor. Case report: Twin male brothers, 9-years-old, presented prolonged retention of the primary central upper incisor. The over-retained teeth in one twin were a mirror image of those in the other twin. The first twin presented a prolonged retention of the tooth 51 whereas the other twin presented a prolonged retention of tooth 61. After radiographic exams the over-retained teeth were extracted. Conclusion: Twins may show similarity in pattern of dental anomalies supporting the influence of genetic factors. In identical twins the location of diagnosed anomalies can be mirror imaged. This fact should lead the professional to examine the pair of twins in order to diagnose any dental anomaly that may be present.

Introdução: Estudos feitos em gêmeos são importantes porque fatores ambientais e genéticos parecem estar relacionados às alterações fenotípicas. Objetivo: Este artigo apresenta um caso raro de gêmeos monozigóticos apresentando imagem em espelho de retenção prolongada de incisivos centrais decíduos superiores homólogos. Relato do caso: Os irmãos gêmeos, com 9 anos de idade, não apresentavam história de trauma orofacial ou doença comum da infância. Após exames clínicos e radiográficos foram identificados a retenção do dente 51 no gêmeo 1 e do dente 61 no gêmeo 2. Em ambos os pacientes, os dentes 11 e o 21 estavam em erupção. O tratamento proposto foi a exodontia dos dentes decíduos com anestesia local e acompanhamento. Conclusão: Gêmeos podem apresentar semelhança no padrão de anomalias dentárias devido à influência de fatores genéticos. Adicionalmente, em gêmeos monozigóticos, a localização das anomalias diagnosticadas pode se apresentar invertidas ou imagem em espelho. Esse fato deve estimular o profissional a examinar o par de gêmeos para diagnosticar qualquer anomalia dentária que possa estar presente. O diagnóstico precoce e tratamento adequados devem ser realizados para evitar danos funcionais e estéticos em pacientes com retenções dentárias.

Pediatricians' perception about the use of antibiotics and dental caries--a preliminary study.

OBJECTIVES: This study aimed to evaluate pediatricians' perception about the use of antibiotics and dental caries. METHODS: One hundred pretested questionnaires containing open and closed questions were distributed to pediatricians from public hospitals in Rio de Janeiro, Brazil. RESULTS: The response rate was 60 percent. Considering the respondents, 73.3 percent frequently prescribed antibiotics, oral administration being the chosen mode (93.3%). Antibiotics were pointed out as being very sweet substances by 53.3 percent of the pediatricians. However, the same percentage did not know what sweetener was responsible for the sweet flavor, and just 40.6 percent recommended oral hygiene after the medicine's intake. Among the pediatricians, 56.7 percent related the use of antibiotics to the occurrence of dental effects, and 40 percent thought that antibiotics could cause a defect of tooth structure. Only one pediatrician (3.2%) associated the presence of fermentable carbohydrates in the composition of these medicines with dental caries. CONCLUSIONS: Pediatricians in this study did not perceive the correct relationship between the presence of fermentable carbohydrates in antibiotics and dental caries. Many of them believed these medicines promoted a defect of tooth structure favoring the development of dental caries. Further studies with a larger sample are necessary.

Perceptions of pediatric patients and guardians about prosthetic appliances.

Forty patients that received prosthetic appliances as part of dental treatment were interviewed about satisfaction with the apparatus. The opinions of the guardians were also considered. The majority of children had complained about missing teeth, but even a greater percentage expressed satisfaction during wear of the prosthetic appliance. Among the guardians, only one of them expressed dissatisfaction with the appliance design. Rehabilitation plan should be discussed with children and guardians considering their perceptions and adequate indications for each case.

Biological restorations as an alternative treatment for primary posterior teeth.

A case of oral rehabilitation in a 4-year-old girl, in which the posterior teeth were restored using biological restorations, is described. The tooth fragments were selected from a bank of tooth tissues and bonded with dual-cure composite cement to prepared teeth. The results were satisfactory regarding retention, aesthetic and mastication, but disadvantages included long clinical appointments, laborious technique and possible fracture or degradation between the margins of the fragment and the tooth surface.

Iodoform Vs Calcium Hydroxide/Zinc Oxide based pastes: 12-month findings of a Randomized Controlled Trial

Abstract This study evaluated clinical and radiographic twelve-month outcomes of root canal treatments (CT) with smear layer removal, performed in primary teeth, using two different root canal filling materials. Pulpectomy was performed on 27 primary teeth with necrosis or irreversible pulpitis, caused by dental caries or trauma, in 23 children (2-7 years old). A single trained operator performed the CT in a single visit in cases without periapical or interradicular radiolucency (PIR) or in multiple visits in cases with PIR. Participants were selected based on specific inclusion and exclusion criteria, and randomly allocated into two groups: Group 1 (G1) - iodoform paste (iodoform + camphorated parachlorophenol + ointment comprising prednisolone acetate 5.0 mg and rifamycin 1.5 mg); Group 2 (G2) - Calen®/ZO paste. Treated teeth were restored with composite resin immediately after the root canal filling. The outcomes were evaluated clinically and radiographically according to specific criteria. Two blinded and standardized evaluators assessed the radiographic outcomes. We used descriptive analyses due to the small sample size. CTs were performed due to caries lesions in 70.4% of the cases and due to trauma in 29.6%. Only one tooth of G1 was unsuccessful; hence, pulpectomy performance in both groups was not influenced by the filling material, nor by any other analyzed variable. The level of the root canal filling was better in the Calen®/ZO group. The clinical and radiographic twelve-month outcomes indicated successful treatment, independently of the root filling material used.

Clinical time and postoperative sensitivity after use of bulk-fill (syringe and capsule) vs. incremental filling composites: a randomized clinical trial

Abstract The objectives of this double-blind randomized clinical trial were to compare (a) the clinical times and (b) the occurrence and severity of postoperative sensitivity, of posterior restoration that used a universal adhesive, in a self-etch or selective enamel-etching technique, along with incremental or bulk-fill composites (presented in syringes or capsules). A total of 295 posterior restorations were placed according to the following groups: SETB - self-etch/bulk-fill in syringe; SETC - self-etch/bulk-fill in capsules; SETI - self-etch/incremental; SEEB - selective enamel-etching/bulk-fill in syringe; SEEC - selective enamel-etching/bulk-fill in capsules; and SEEI - selective enamel-etching/incremental. Clinical time was assessed by a reason (s/mm3) between the total volume of resin inserted and the total time required to perform the restorations. Postoperative sensitivity was evaluated using two scales (Numeric Rating Scale and Visual Analogue Scale). Mean clinical time results, analyzed by Wald's Chi-square, showed significant statistical differences among all groups (p<0.001), indicating that the restorative strategy affected the time required for the restoration. A generalized estimating equation model statistical analysis, performed to compare postoperative sensitivity, showed that neither the restorative technique, the adhesive strategy nor the presentation mode of the bulk-fill composite affected the overall risk of postoperative sensitivity (4.06 [2.22-6.81]). The use of bulk-fill composite, presented in capsules or syringes, is less time consuming and does not increase the risk or intensity of postoperative sensitivity relative to the traditional incremental technique.

A importância da equipe multidisciplinar no manejo clínico frente à alteração na cronologia de irrupção / The importance of a multidisciplinary team in the clinical management of chronological changes of teeth

A cronologia de irrupção é de fundamental importância em se tratando da busca por uma oclusão balanceada. Contudo, certas patologias podem alterar a cronologia e com isso influenciar o estabelecimento da oclusão. O odontoma é o tipo mais comum de tumor odontogênico, sendo representado por 70% dos casos cuja formação é definida como má-formação benigna. A localização mais frequente é observada na região anterior da maxila, sendo o dente canino o mais envolvido, entretanto exceções tem sido observada. Este trabalho teve por objetivo avaliar a importância da inter-relação de especialidades no diagnóstico e conduta frente à alterações na cronologia de irrupção de dentes permanentes. Realizou-se revisão da literatura sobre a temática, nas bases Medline via PubMed, SciELO e Bireme, até novembro de 2017. Os descritores utilizados foram "pediatric dentistry", "unerupted" e "dental eruption". Pode-se constatar a existência de poucos trabalhos descrevendo a importância da inter-relação entre especialidades, sendo mais divulgados revisões de literatura sobre determinadas patologias, bem como relatos de casos, com as condutas frente a existência de tais patologias. Diante do exposto, acredita-se que quando as especialidades trabalham em conjunto, o desdobramento do caso clínico faz-se de forma adequada, beneficiando o prognóstico, além de melhorar a qualidade de vida do paciente.

The chronology of irruption has fundamental role when it is considered the balanced occlusion. However, some pathologies may alter the chronology and thereby influence the establishment of the occlusion. This study aimed to evaluate the importance of the interrelation of specialties in the diagnosis and management of changes in the chronology of permanent teeth eruption. In the first paper, a review of the literature on the subject was carried out in the Medline databases via PubMed, SciELO and Bireme, until November 2017. The descriptors used were "pediatric dentistry", "unerupted" e "dental eruption". It was possible to verify the existence of few studies describing the importance of the interrelation between specialties, being more published literature reviews on certain pathologies, as well as case reports, with managements used with such pathologies. It could be concluded that when the different specialties work together, the unfolding of the clinical case is done adequately, benefiting the prognosis, besides improving the quality of life of the patient.
