RESUMEN

Purpose: To evaluate parental knowledge of the importance of the permanent first molar (PFM).
Methods: Three hundred and eighty parents filled a 22-item questionnaire assisted by a trained investigator. They were asked to indicate the correct answer from the given list of options in order to assess their awareness about the eruption sequence of primary and permanent teeth and the importance of PFMs. Assessment of parental attitude toward preventive management and treatment of carious or infected permanent teeth was done, together with their willingness to comply with the treatment options suggested for such teeth. The sequelae of caries in PFM and their effect on the growth and development of the face and jaws were assessed as well.
Results: Seventy-five percent and 72.4 percent of parents responded correctly about the number of primary and permanent teeth. When parents were asked about the chronology of tooth eruption, 53.9 percent of parents thought that the PFM erupted between 10 and 12 years of age. Almost 65 percent of the parents said they would start brushing their child's teeth after all the primary teeth erupt. Forty-five percent agreed to the extraction of PFMs, considering them to be primary teeth, as they felt unnecessary to treat a carious tooth that was going to exfoliate.
Conclusion: Parents often based their decision for dental treatment choices for their children on lack of information as they were unaware about the eruption and importance of PFM. There is a need to emphasize the importance of PFM during interaction with parents.

RESUMEN

Burkitt lymphoma (BL) is a rare and aggressive malignant neoplasm frequently involving the jawbones in children. The main purpose of this article is to report the case of a nine-year-old boy with widespread BL diagnosed through oral findings. The patient was referred after complaining of dental mobility for two weeks. The physical examination revealed premature eruption of permanent teeth. The periapical radiographic examination showed a diffuse bone rarefaction in the involved area. An incisional biopsy was performed, leading to the diagnosis of BL. The patient was then treated with chemotherapy and is free of disease after an 18-month follow-up. The main signs and symptoms of an oral BL could mimic a dental problem, thus it is extremely important to be knowledgeable about this disease, which can be fatal without early diagnosis and treatment.

RESUMEN

Aim: Single- and multiple-visit root canal treatment has been the subject of long-standing debate in the endodontic community, so the purpose of this study was to determine the incidence of postoperative flare-up after single- and multiple-visit endodontic therapy in permanent teeth. Materials and Methods: A total of 65 children aged >10 years who underwent root canal treatment were randomly categorized equally into two treatment groups: the first group underwent single-visit treatment, and the other group underwent multiple-visit therapy. The visual analog scale was employed to evaluate pain preoperatively and postoperatively after obturation. Recall visits were carried out after 1 week, 1 and 3, 6 and 9 months. The Statistical Package for the Social Sciences version 15.0 was employed for statistical analysis. Results: Except at the baseline, at all the other time intervals, the mean pain score in the multiple-visit group was higher as compared to that of the single-visit group; statistically no significant difference was found. Conclusion: The mean pain score in the single-visit group was lower as compared to that of the multiple-visit group; however, the difference between the two groups was statistically significant (P > 0.05).

RESUMEN

INTRODUCTION: The global objectives of WHO in the field of oral health by 2020 include the average intensity of caries among 12-year-old children no more than 1.5 by the DMFT index. In Samara the value of the DMFT among the adolescents at age 12 is 3.5. AIM: To identify the appropriate timing for a launching of community-based schemes of dental caries prevention of permanent teeth for children of Samara. MATERIAL AND METHODS: In a cross-sectoral multisample research from March to May 2017, the time of eruption and intensity of caries of the first permanent molars among children in Samara were studied. A total of 405 children aged 5 to 8, attending preschool and school educational institutions were examined. The quantity and the stage of eruption of the first permanent molars were assessed; the initial and manifest forms of caries were considered during the calculation of indexes of caries intensity of teeth and surfaces. RESULTS: One to four first permanent molars were erupted among 26.3% of children aged 5, at an average 0.6±0.14 per one surveyed, the prevalence of caries of the first permanent molars was equal to 1.3%, including 1.3% of the initial carious defeats. In 6-year-old children - 65% had the first permanent molars, at an average of 2.38±0.199, and the prevalence of caries in these teeth was 29.63%, including initial forms of caries 27.16%. The results among 7-year-old children - 87.18% and 3.12±0.156, 60.3% and 51.28%, respectively. In 8-year-old children these figures were equal: 97.26%, 3.79±0.091, 68.49% and 60.27%, respectively. The rate of eruption of the first permanent molars and the prevalence of their carious lesions among girls was significantly higher than among boys. CONCLUSION: The optimal age of children of Samara for inclusion in the regional programs of dental caries prevention is the age of 4 years - the age of the beginning of the first permanent molar eruption.

RESUMEN

To analyze whether a correlation exists between the caries status (Decayed, Missing and Filled Teeth, DMFT Index) of the first permanent molars (FPMs) and that of the full permanent dentition of Mexican adolescents, and to propose its use in large epidemiological studies of dental caries.We conducted a cross-sectional study of 1538 adolescents from 12 to 15 years old. Based on a clinical oral examination, we determined the DMFT Indices of their FPMs (FPM-DMFT) and of their full permanent dentition (comprehensive DMFT Index). We explored each FPM to determine whether it was with or without caries, filled, missing or sealed. For our statistical analysis, we used Fisher exact test and Spearman correlation in Stata software.After examining a total of 6157 FPMs, we found that 56.8% of our sample of adolescents had no caries in their 4 FPMs whereas 4.9% experienced caries in all 4. No significant differences emerged by sex (P > .05); however, by age, the older adolescents experienced greater FPM-DMFT (P < .05). Analysis yielded a correlation of r = 0.8693 between the FPM-DMFT and comprehensive DMFT scores (P < .0001) of participants. The underestimation of caries prevalence (DMFT > 0) was 5.4% (48.6% vs 43.2%), while the DMFT Index was underestimated at 0.34 (1.15 vs 0.81).The strong correlation between the FPM-DMFT and comprehensive DMFT Indices suggests that overall caries status can be inferred on the basis of FPM caries status. This evidence is useful when conducting large epidemiological studies such as national surveys.

RESUMEN

Background: The incidence of traumatic dental injuries is affected by social, environmental, and socioeconomic variables. For this reason, epidemiological studies are an important tool for increasing social consciousness and guiding the necessary precautions about trauma. Objectives: The study aims to analyze the epidemiological and clinical data of traumatic dental injuries in patients attending Department of Pediatric Dentistry, Faculty of Dentistry, Bulent Ecevit University, from around Zonguldak, over a period of 3 years (between January 2014 and January 2017). Materials and Methods: Data obtained from trauma charts were analyzed for age, sex, the time elapsed between injury and referral to the clinic, cause of trauma, number, and type of the teeth, type of the trauma, treatment, and seasonal distribution. Results: In all, 188 patients, including 120 boys and 68 girls with a total of 316 traumatized teeth were evaluated. Most (61.7%) of the patients were 7-12 years old (the remaining 38.3% were 1-6 years old). The main cause of injury in both genders was falling. The most common types of trauma were subluxation in primary teeth and enamel dentin fracture in permanent teeth. In the primary dentition, examination and follow-up were the most applied treatments, whereas in permanent dentition, restorative treatments were the most applied treatments. Conclusion: Early intervention is important for the prognosis of the injured tooth. However, except for severe injuries, the rate of referral to the clinic after trauma was low. Therefore, the level of social awareness and knowledge of trauma should be increased.

RESUMEN

BACKGROUND: Limited information exists regarding the use of stainless steel crowns (SSCs) in permanent teeth. The objective of this retrospective cohort study was to present the long-term clinical outcomes of the SSC compared with those of amalgam and composite resin restorations and the SSC radiographic outcomes in a special-needs population. METHODS: This study included 271 patients with at least 1 SSC restoration from the Mount Sinai Hospital Dentistry Clinic for Persons with Special Needs in Toronto, Ontario, Canada. A total of 2,621 posterior permanent tooth restorations were documented: 766 SSCs, 1,651 amalgam restorations, and 204 composite resin restorations. Clinical analysis included patient demographics, treatment parameters, and outcome assessments for each restoration recorded. Radiographic analysis of SSC restorations included 127 bite-wing radiographs and 118 periapical radiographs, measurement of interproximal bone loss, and assessment of periapical status using the Periapical Index Scale. RESULTS: The 10-year survival rates for new SSC and amalgam restorations were 79.2% and 63.5%, respectively. The 91 SSC failures included 2 recementations, 33 replacements, and 56 extractions. Primary diagnoses at the time of failure included chronic periodontal disease (25) and loose or lost SSCs (24). Of the 528 failed conventional restorations that were replaced, 60% were replaced with SSCs. The mean alveolar bone loss from mesial and distal sites was 1.36 millimeters and 1.40 mm, respectively. Therefore, 93% of the sites recorded were less than 2 mm and classified as healthy. All pre-SCC and post-SSC periapical radiographs had healthy Periapical Index Scale scores (1 or 2) recorded over an average duration of 8.4 years (1-29.1 years). CONCLUSIONS: SSCs are a durable treatment option for the restoration of the posterior permanent dentition. PRACTICAL IMPLICATIONS: Posterior permanent teeth restored with stainless steel crowns can be expected to last for 10 years and represent a viable treatment choice for severely carious or fractured posterior permanent teeth.

RESUMEN

INTRODUCTION: Pulpotomy in mature permanent cariously exposed teeth preserves the remaining pulp tissues, but long-term outcomes of the pulp and the restoration are unknown. This prospective study examined the immediate and long-term status of the pulp and the restored tooth and identified potential predictors of early and late failures in teeth that were asymptomatic or experiencing only mild symptoms at the time of treatment. METHODS: Pulpotomy was performed using the aseptic technique and a tricalcium silicate cement under local anesthesia. Teeth were assessed for up to 5 years for pulpal and apical signs and symptoms, restorative marginal integrity, and periodontal health. RESULTS: Fifty-two patients (61 teeth) with a median age of 40 years (range, 21-75 years) were included in this study; 17 (32.7%) men and 35 (67.3%) women were treated and reviewed. Overall pulp survival was 90.2% (95% confidence interval, 79.8%-96.3%); 6 teeth developed irreversible pulpitis or pulp necrosis when the restoration was intact. Preoperative pain was a potential predictor (P < .05) for early failure. Eleven late failures occurred between 2 and 4 years: 1 tooth with intact coronal restoration had pulp necrosis and asymptomatic apical periodontitis, 4 had recurrent caries resulting in asymptomatic apical periodontitis, 4 remained vital and only needed new restorations, 1 was unrestorable, and 1 was extracted for periodontal reasons. The type of definitive restoration was a potential predictor for late failure (P < .05). CONCLUSIONS: Carious pulp exposures in asymptomatic mature permanent teeth can be predictably managed by pulpotomy using a tricalcium silicate cement. Short-term failures were few and managed by pulpectomy. Appropriate coronal restoration is critical to long-term success.

RESUMEN

INTRODUCTION: Tooth replantation is the treatment of choice for avulsion, even though its long-term prognosis shows great variability and few studies have adopted survival analysis to evaluate the fate of such teeth. The present study aimed to evaluate both the survival rate of replanted permanent teeth after traumatic avulsion as well as its clinical and demographic determinants. METHODS: Records from 576 patients treated at the Dental Trauma Clinic at the Federal University of Minas Gerais, Brazil, were analyzed to collect clinical and radiographic data. Kaplan-Meier curves and a multivariate Cox regression model were used to estimate the probability of replanted teeth remaining functional in the mouth and to determine prognostic factors. RESULTS: The post-replantation survival rate was 50% after 5.5 years. Immature teeth presented an increase of 51.3% in the loss rate (P = .002). Each additional year in the patient's age at the time of trauma, up to the limit of 16 years, reduced the loss rate of replanted teeth by 15% (P < .001). The storage of the avulsed teeth in milk decreased the loss rate of replanted teeth by 56.4% (P = .015) when compared with those kept dry. CONCLUSIONS: The overall survival rate after replantation of permanent teeeth was 50% after 5.5 years. Advanced stages of root development, together with the increase in the patient's age at the moment of trauma, up to the limit of 16 years, were good prognostic factors for tooth survival. The storage of avulsed teeth in milk was also associated with enhanced tooth survival after replantation.

RESUMEN

OBJECTIVES: This study aimed to systematically review the literature regarding the risk of selective removal-in comparison with stepwise and nonselective removal-of carious tissue in permanent teeth. MATERIALS AND METHODS: Controlled clinical trials and cohort studies involving patients with dental caries in permanent teeth were included. Databases used were PubMed, Embase, and Scopus. The test group should be composed of patients undergoing selective removal of carious tissues, and the control group should comprise patients undergoing nonselective removal and/or stepwise removal of carious tissue. Laboratory tests, studies on primary teeth, and studies that used temporary restorations were excluded, as were literature reviews. The primary outcome was overall success of maintaining pulpal health (both clinically and radiographically). Quality of the restoration, pulp exposure, dentin deposition, and microbiological examination were also assessed. A meta-analysis, using the pooled risk ratio (RR) and its 95% confidence interval (CI), was performed to assess the success of maintaining pulpal health, using the different control treatments as a subgroup analysis. RESULTS: A total of 2333 articles were retrieved, of which 10 were included in the systematic review and four in the meta-analysis. In the qualitative evaluation, the control groups presented a higher risk of pulp exposure in relation to the selective removal. In the meta-analysis, the selective carious tissue removal showed significantly higher overall success (RR, 95% CI 1.11, 1.02-1.21). CONCLUSIONS: The selective carious tissue removal presented higher success of maintaining pulpal health. CLINICAL RELEVANCE: In permanent teeth, selective carious tissue removal should be performed, as this technique results in lower numbers of pulp complications, such as pulp exposure, as compared with nonselective removal.

RESUMEN

Traumatic dental injuries are highly prevalent among preschool children. When occurring at a very young age (prior to the eruption of the primary teeth), such trauma can disturb the normal development of the permanent dentition and, more rarely, affect the primary dentition. This report describes a case of a patient who suffered dentoalveolar trauma at six months of age that caused rare developmental problems in the primary dentition, such as impaction, dilacerations, hypoplasia, and odontoma. Imaging revealed that alterations also occurred in the permanent dentition. This report demonstrates that dentoalveolar trauma prior to complete development of the dentition and even before the eruption of the primary teeth can lead to highly uncommon abnormalities in the primary dentition. Moreover, there may be repercussions in the permanent dentition when the germs of these teeth are injured by the intraosseous displacement of primary teeth.

RESUMEN

AIM: The aim of this study was to quantitatively compare conventional composite removal and composite removal supported by the fluorescence-aided identification technique (FIT) regarding the completeness, selectivity, and duration of the procedure in directly restored permanent posterior teeth. METHODS AND MATERIALS: Two operators removed standardized direct class II composite restorations (n=32 per operator) in human tooth models under simulated clinical conditions. According to a randomized allocation scheme, removal was performed with either the conventional technique (contra-angle handpiece) or supported by FIT. The duration of each removal procedure was recorded. The completeness and selectivity were volumetrically assessed through superimposition of three-dimensional surface scans. Statistical significance was tested by examining the overlap of 95% confidence intervals (CI). Multiple comparison was performed with Tukey tests for each variable. RESULTS: Compared with the conventional technique, composite removal with FIT was faster (329 seconds [95% confidence interval (CI): 268-390 seconds] vs 179 seconds [95% CI: 150-208 seconds]), generated less tooth substance loss (4.53 mm3 [95% CI: 3.77-5.30 mm3] vs 2.77 mm3 [95% CI: 2.11-3.43 mm3]), and left behind less composite residue (1.58 mm3 [95% CI: 1.23-1.94 mm3] vs 0.53 mm3 [95% CI: 0.39-0.67 mm3]). CONCLUSION: Within the limitations of this in vitro study, FIT facilitated the selective and expeditious removal of tooth-colored composites in directly restored posterior teeth.

RESUMEN

BACKGROUND: Eruption timing of permanent teeth, particularly first and second molars, is of great importance due to its influence on occlusion, caries risk and timing of preventive and orthodontic intervention. AIM: To evaluate the evidence assessing the correlation between obesity and eruption time of first and second permanent molars in children under 16 years of age as compared to normal-weight children. A secondary aim was to assess the total number of erupted teeth in both groups. METHODS: A systematic search of databases including PubMed, MEDLINE, EMBASE, Scopus and Web of Science was conducted. Studies that assessed the effect of body mass index (BMI), adjusted BMI or z scores on dental eruption were included. National Institute of Health 'Quality Assessment Tool for Observational Cohort and Cross-sectional Studies' was used to assess the quality of included papers. A random-effects model with its 95% confidence intervals (CIs) was considered for meta-analysis. RESULTS: A total of 381 papers were screened following duplicate removal. Twenty-six papers were read in full text, of which 19 were excluded. Seven studies were included in this review; one was longitudinal, and six were cross-sectional in design. A positive association of dental eruption with obesity was noted in six studies. Two studies were included in the explorative meta-analysis, the results of which indicated that obese, 12-year-olds are likely to have one more erupted tooth than their counterparts with a mean difference (MD) of (0.99, 95% CI 0.628-1.352). CONCLUSION: There appears to be a positive correlation between obesity and dental eruption including the eruption timing of first and second permanent molars. Main risk of bias arises from the cross-sectional nature of included studies and lack of control of potential confounders. Further high-quality evidence is required to elucidate this association.

RESUMEN

PURPOSE: The purpose of the study was the investigation of supernumerary teeth (ST) in the permanent dentition of patients with neurofibromatosis type 1 (NF1). MATERIAL AND METHODS: The panoramic radiographs of 200 NF1 patients were analysed for ST. The potential impact of certain neurogenic facial tumours on the measured variable was investigated separately. The results were compared to dental findings in panoramic radiographs of 200 age- and sex-matched controls. RESULTS: The total number of ST in all individuals was 23 in 12 patients (3% of total population). However, all ST had developed in the group of NF1 patients (6%), (p = 0.0004). ST were particularly common distal to the molar region. Although ST occur in the region of facial plexiform neurofibroma, the numerical aberrations of the dentition are independent of specific type of facial nerve sheath tumour. CONCLUSION: The unusual accumulation of ST in the terminal sections of molar development could be an indicator of preferred points of developmental disorder, in which the genetic predisposition of the patient is involved. Reviewing the results of other NF1 patient collectives is desirable.

RESUMEN

OBJECTIVES: To evaluate the in vitro effects of radiotherapy (RT) on the morphological surface of the enamel and dentin and to determine the best adhesive system and most appropriate time to restore teeth in head and neck cancer patients. METHODS: Sixty third molars were cut into 120 enamel fragments and 120 dentin fragments and divided into four groups (n = 30): G1 (control): nonirradiated, only restorative procedure; G2: restorative procedure immediately before RT; G3: restorative procedure immediately after RT; and G4: restorative procedure 6 months after RT. Each group was divided into two subgroups: Adper™ Single Bond 2 (SB) and Clearfill SE Bond (CL) based on the material used. After RT and restorative procedures, the specimens were subjected to confocal microscopy and shear bond strength test. Data were analyzed using a two-way ANOVA followed by Tukey's test at a significance level of 5%. RESULTS: Morphological changes were observed in both substrates after a cumulative dose of 40 Gy, and after 60 Gy, the changes were more evident in both substrates. CL had the highest strength values in both substrates (p < 0.05), and G2 had the lowest strength values for the enamel and dentin (p < 0.05). CONCLUSIONS: Based on the in vitro study results, we can conclude that RT substantially changes the morphological surface of enamel and dentin and impairs the bond strength. The Clearfill system yielded better results than Adper Single Bond 2, and restoring teeth before RT resulted in the worst results in both substrates.

RESUMEN

Revascularization endodontic procedures commonly require multiple treatment sessions. However, single visit procedures may be advantageous from the clinical and patient management standpoints. The purpose of this review was to evaluate the outcomes of single-visit revascularization endodontic procedures for the management of immature permanent teeth with non-vital pulp. Two electronic databases (Scopus and PubMed) were searched, from their inception to July 2018, for studies that assessed clinical and/or radiographic and/or histologic outcomes of single-visit revascularization endodontic procedures performed in immature permanent teeth with non-vital pulp. Case reports, animal studies and clinical trials were included. The quality of case reports was appraised by Joanna Briggs Institute Critical Appraisal Checklist for Case Reports. The quality of randomized clinical trials was assessed by the revised Cochrane risk of bias tool for randomized trials. The risk of bias for animal studies was assessed using SYRCLE's risk of bias tool. Tabulation followed by narrative synthesis was used to draw conclusions. Seven studies satisfied the selection criteria. Five were classified as case reports, one as a randomized clinical trial and one as animal study. The latter presented with a high risk of bias, whilst the remaining showed a low risk. The evidence supporting the potential use of single-visit revascularization endodontic procedures is scarce. Successful single-visit revascularization endodontic procedures commonly include the use of high concentrations of sodium hypochlorite and EDTA combined with the use of agitation systems. Further clinical trials with long term follow up are needed to confirm the results of the current review.

RESUMEN

BACKGROUND: The meta-analysis of the data collected in the years 1939-1993 clearly shows an increasing incidence of hypodontia. The disorder is characterized by a congenital absence of deciduous or permanent teeth. It is a significant esthetical and functional problem, which may negatively affect the patient's psychosocial development. OBJECTIVES: The aim of the study was to determine the scale of hypodontia using a sample of Polish orthodontic patients. MATERIAL AND METHODS: The orthopantomograms and medical records of 674 patients aged 6-15 years (376 girls and 298 boys) were analyzed in order to identify dental agenesis. Deciduous and wisdom teeth were excluded from the study. Data regarding gender, the location of the disorder as well as the number and type of missing buds was recorded. RESULTS: Hypodontia was found in 11.6% of the subjects (7.6% girls and 4% boys), more often in the mandible (44.9%) than in the maxilla (28.2%) or in both jaws (26.9%), and these differences were statistically significant (p = 0.096). The occurrence rates of uniand bilateral hypodontia were similar: 51.3% and 48.7%, respectively. The incidence of left-sided hypodontia (37.2%) significantly prevailed over rightsided hypodontia (14.1%) (p < 0.01). Tooth 35 was the most frequently missing one (13.5%). CONCLUSIONS: The large discrepancy in hypodontia prevalence indicates that geographical differences and varying sample sizes greatly affect the results of studies. The literature lacks comprehensive studies regarding hypodontia in Poland. More studies with similar sample sizes and selection criteria need to be carried out. Through an early detection of hypodontia, it is possible to plan comprehensive, interdisciplinary treatment. Regardless of the discrepancies in the literature as to the exact location of the problem, hypodontia affects over 10% of the population of patients treated orthodontically, which justifies the need to study this issue.

RESUMEN

The aim of the present study was to identify the characteristics and severity of tooth wear in children aged 2 to 5 years attending a kindergarten in the city of Medellin. The study population comprised 92 children aged 2 to 5 years attending a kindergarten in Medellin; the final sample included 86 children selected using a non-probabilistic sampling method. All assessments were performed using the index devised by Hansson and Nilner (1989). Prevalence of tooth wear in the studied population was 100%. The observed results confirm previous findings showing that the severity of tooth wear is proportionally related with increase in age, and is mainly due to the physiological wear of teeth. No significant differences in tooth wear facets were observed among the different types of teeth (incisors, canines, molars). It is necessary to develop validated, precise, and comparable indices that allow establishing the etiology and orienting treatment of non-physiological tooth wear.

RESUMEN

OBJECTIVES: This study aimed to evaluate the association between dental implants and cognitive function in community-dwelling older adults. METHODS: Data were collected from the baseline survey (2016-2017) of the Korean Frailty and Aging Cohort Study. The study sample comprised 1115 community-dwelling people aged 70 years to 84 years who had 0-19 natural teeth. Dental implants and natural teeth were identified by panoramic radiography, while the cognitive function was assessed by the Korean version of the Mini-Mental State Examination (MMSE-KC). The association between dental implants and cognitive function was analyzed by multiple linear regression. Sensitivity analysis was performed to test for potential bias. RESULTS: The mean number of natural teeth in the study population was 9.50 (standard deviation [SD], 6.42), and the mean MMSE-KC score was 24.93 (SD, 3.55). In the simple univariate analysis, tooth replacement, age, sex, smoking status, alcohol consumption, body mass index, osteoporosis, number of natural teeth, periodontitis, chewing discomfort, tooth-brushing frequency, education level, monthly household income, participation in economic activity, living alone, and marital status had a significant impact on the association. After adjusting for confounders, the association between dental implants and cognitive function remained significant (B, 0.85; standard error, 0.40; p<0.05). Age, body mass index, periodontitis, tooth-brushing frequency, and education level were also significantly associated with cognitive function. The results of the sensitivity analyses were consistent with those of the primary analysis. CONCLUSIONS: Dental implants were associated with cognitive function in older adults living in the community. Dental implants as tooth replacements may play a role in preserving cognitive function.

RESUMEN

Iatrogenic perforation is a procedural incident that may occur in endodontic treatments of primary and/or permanent teeth. Prognosis may be favorable if a complete seal with biomaterial is immediately established. Several materials, including glass-ionomer cement (GIC), have been used to seal different types of perforation defects. GIC is considered to be biocompatible, nontoxic, and non-irritating, and promotes bone healing and cementum regeneration. In the present case, GIC was used to treat an endodontic perforation. The perforation was cleaned with periodontal curettes and sealed with GIC. A reintervention was needed in which sealing was performed with a light-curing GIC, a material that was less rough than the initial material used. After 2 years, the absence of periradicular radiolucent lesions, pain, and swelling along with functional tooth stability indicated a successful outcome of sealing perforation in the case.
