RESUMO

Non-metric Dental Crown Traits are a principal source of information in forensic dentistry. However, inadequate data on the prevalence of these traits prompted this study to determine the frequency, sexual dimorphism and degree of inter-trait association in two different populations of India. Dichotomized data on the existence of non-metric features were recorded among individuals from Odisha (n=506) and Kerala (n=536) between 15 to 30 years of age. Cusp of Carabelli is the most common trait to occur (48 %) followed by shovelling of incisors (15%) and Bushman canine (14%). Bushman canine (p=0.045) and Cusp of Carabelli (p = 0.041) were found to be significantly expressed in Odisha and Kerala populations respectively. A strong association between shovelling of central incisor and Bushman canine with a likelihood ratio of 14.041 (p=0.001) was observed. This study will help in characterizing the Indian dentition and post-mortem dental profiling.

RESUMO

Objetivo: Presentar la terapia regenerativa como una al- ternativa para la resolución de un caso de traumatismo denta- rio en un diente permanente incompletamente desarrollado. Caso clínico: Se realizó el tratamiento de un incisivo central superior con mortificación pulpar y periodontitis api- cal aguda subsecuente a trauma dental en un paciente de 8 años de edad. Se aplicó el protocolo de regeneración pulpar recomendado por la Asociación Americana de Endodoncia. Se estimuló la formación de un coágulo en el interior del con- ducto a partir de los tejidos periapicales, previa desinfección con la pasta triple antibiótica, y finalmente se colocó mineral trióxido agregado coronal a este. Se obtuvo así una matriz es- teril que permitió el crecimiento de nuevo tejido y se realiza- ron controles periódicos durante 4 años. Se constató silencio clínico. Radiográficamente, se observó la formación de tejido sobre las paredes del conducto y el cierre apical. Conclusión: La terapia regenerativa como alternativa de tratamiento, en este caso, permitió la disminución de la luz del conducto por el depósito de tejidos calcificados y el cierre del foramen apical, mejorando el pronóstico de la pieza dentaria (AU)


Aim: To present pulp regeneration therapy as an alter- native to resolve dental trauma in immature permanent teeth. Clinical case: We report a clinical case of an immature central superior incisor with pulp mortification and acute api- cal periodontitis subsequent to dental trauma, in an 8 year old patient. The pulp Regeneration protocol recommended by the American Endodontics Association was applied. We stimulated a clot formation inside the duct from periapical tissues and after disinfection with a mixture of three antibi- otics mineral trioxide aggregated was finally place coronal to the clot. Thus a sterile matrix was obtained that allowed new tissue's growth. Periodic check-up visits were carried out over a 4 years period. Clinical silence was observed. Tissue formation on duct walls and apical closure were radiograph- ically detected (AU) Conclusion: Regenerative therapy is an alternative for the treatment of immature permanent teeth, in ths clinical case it allowed the reduction of the width of the duct by the opposition of hard tissues and the closure of the apical fora- men improving the forecast of these teeth.

RESUMO

Agenesis of the permanent dentition is rare. This report describes a 20-year-old woman with 19 deciduous teeth, a single permanent mandibular premolar, and other physical traits associated with ectodermal dysplasia. The patient demonstrated esthetic parameters associated with maxillomandibular alveolar insufficiency, and her chief complaints were directed toward esthetics and the potential impact of restorative choices on function. Three typical options for restoration include overdentures, removable partial dentures, or implant-supported prostheses replacing her natural dentition. This report illustrates a fully integrated digital approach to treatment planning, the fabrication of a computer-aided design/computer-assisted manufacture surgical guide and provisional restoration, guided implant placement, and definitive restoration using monolithic zirconia implant-supported fixed dental prostheses. The lifelong management of this rehabilitation is an acknowledged challenge.

RESUMO

This fourth in a series of 5 articles in the context of the 2017 Kies-voor-Tanden study presents the results for 17-year-olds. 34% of the 17-year-olds had flawless permanent teeth. In 2017, there were still differences in oral health among the socio-economic groups, to the advantage of the high socio-economic group. The oral health of 17-year-olds had stagnated during the previous 6 years and even appeared to be deteriorating according to some indicators. In addition, knowledge about the dental insurance system after the 18th birthday was poor. Conclusion: The oral health of 17-year-olds had not improved in the previous years. This trend must be followed by monitoring research. In addition, interventions to improve the oral health, knowledge and behaviour of adolescents should be set up and evaluated.

RESUMO

Aim: The aim of this study was to evaluate demographic and clinical factors involved in the immediate seeking of care after traumatic dental injury (TDI) in Brazilian children. Materials and Methods: Records from 74 patients, age ranged 1-11 years, who sought treatment at the School of Dentistry of Ribeirão Preto at University of São Paulo, Brazil, were collected. Data was analyzed using the Epi Info 7.0 software by t-test, odds ratio calculation, Chi-square, or Fisher's exact tests. Results: Twenty-three (31.1%) sought dental treatment immediately and 51 (68.9%) did not seek dental treatment immediately. The most common type of trauma was lateral luxation (44.6%). In primary teeth, 31 cases (60.78%) involved the soft tissue and 16 (39.2%) involved hard tissue injuries. While in permanent teeth, 20 cases (40%) involved soft tissue and 24 (60%) involved hard tissue injuries had more traumas in the hard tissue (P = 0.04). The type of injury and dentition was not associated with the time that the guardians sought dental treatment (P > 0.05). None of the factors were involved in immediately seeking care after TDI. Conclusion: Moreover, the majority of parents/caregivers did not immediately seek dental treatment after TDI, regardless of the type of injury.

RESUMO

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.

RESUMO

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).

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Background: Clefts are common birth defects, usually accompanied by various malformations that include malocclusions, and may be associated with tooth decay. The aim of this study was to assess the malocclusion and caries status of the patients with unrepaired clefts who presented at the National Orthopaedic Hospital Enugu. Subjects and Methods: A cross-sectional, descriptive study was conducted among patients with unrepaired cleft lip and/or palate that presented at the National Orthopaedic Hospital, Enugu between January 2009 and December 2011. Detailed records of 140 patients with cleft deformities who presented to the hospital within the study period were analyzed for the cleft pattern, whereas those patients above 6 years of age (52 patients) were analyzed for malocclusion using the Angle's classification of malocclusion. Assessment for dental caries according to WHO guidelines was made for all the patients. Result: There were 74 males and 66 females. Cleft lip with or without alveolus involvement had equal prevalence (47.1%) (66 patients) with combined cleft lip and palate; eight patients had isolated cleft palate (4.71%). Angle's class 1 malocclusion was statistically significantly higher than other classes (P = 0.000). Class I malocclusion was seen in 38 patients (73.1%), whereas class 111 was seen in 8 patients (15.4%) and class 11 in 6 patients (11.5%). Eight patients (100%) who developed class 111 malocclusion all had a hard palatal defect. Proclining of maxillary anterior teeth (increased overjet) was the most common orthodontic anomalies, reported in 25 patients (48.1%) (P = 0.002). Caries prevalence of 12.9% was observed in this study. Caries experience was statistically significantly higher in deciduous than permanent teeth (P = 0.002). Conclusion: The high prevalence of malocclusion in these cleft patients emphasizes the need for an interdisciplinary team approach and early inclusion of dental care especially oral hygiene to prevent tooth decays.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
