Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.

Objective: PTFE tape, which is commonly used as plumber's tape is an inorganic, non-fibrous, ribbon like material. The aim of this study was to evaluate PTFE tape as endodontic spacer material and to compare it with commonly used spacer material that is cotton, in primary teeth. Study Design: Seventeen children undergoing pulpectomy of lower second primary molar bilaterally were included in the study. Cotton and PTFE tape were placed as spacers on each side randomly. Samples were taken from the access cavity at baseline and after seven days to check for microbial leakage. Spacer materials were also checked for microbial contamination. Results: The results revealed that there was a significant increase in the bacterial colony count after seven days in cotton group. The access cavities were also positive for microbial leakage in the cotton group where the spacers showed positive growth. In PTFE group only two samples showed microbial contamination of spacer and out of two only one sample showed contamination of access cavity along with spacer. Conclusion: Within the limitations of this study, it can be concluded that PTFE tape performed better than cotton as endodontic spacer material. Thus, PTFE tape can be recommended as an endodontic spacer material as an alternative to cotton in primary teeth.

Caries Lesions

Caries has traditionally been assessed with WHO criteria including only obvious caries lesions. ICDAS has been developed to detect also the enamel caries lesions. This study aims to study caries and the associations of the number of caries lesions between the permanent and primary molars with ICDAS in the mixed dentition of the first and second grade primary school children. The clinical examinations of 485 children were conducted by four examiners with high reproducibility (inter- and intraexaminer kappas >0.9). The mean number of caries lesions—especially dentine caries—seemed to be higher in the second primary molars than in the first permanent molars. There were significant correlations between the number of lesions on occlusal and lingual surfaces between the primary and permanent molars. Enamel caries lesions, restorations, and caries experience did not increase according to age. Therefore, caries might be increasing in this population. As a conclusion, ICDAS recording seems to give appropriate information from the occurrence of caries lesions and its correlations between the primary and permanent teeth and surfaces.

Jaw Development

Humans have two sets of teeth, deciduous teeth and permanent teeth. When primary teeth fall out, permanent teeth erupt to maintain the chewing function and jaw development. Shedding occurs with increasing level of mobility in primary teeth as a result of root resorption. This report describes an uncommon clinical case that occurred in primary molars with internal resorption and pinkish discoloration. Pink tooth is worrisome for children and parents. Children should have their teeth examined on a regular basis to detect any problems in the process of tooth shedding and eruption.

Hypophosphatasia (HPP) is a rare genetic disorder; affected patients may experience early exfoliation of primary teeth, especially anterior teeth. However, there have been few reports regarding longitudinal follow-up for primary teeth, especially posterior teeth, until their replacement with permanent teeth. Here, we describe a patient with HPP who underwent follow-up from 1 to 9 years of age. A 14-month-old boy was referred to our hospital with the chief complaint of early loss of primary anterior teeth. He was diagnosed with odonto-type HPP by his pediatrician, due to low serum alkaline phosphatase concentration and early exfoliation of primary teeth with bone hypomineralization. The patient experienced exfoliation of three additional primary anterior teeth by 4 years and 1 month of age. Partial dentures were applied for space maintenance; there were no problems regarding subsequent replacement with permanent teeth in the anterior region. However, the primary mandibular right first molar appeared to be submerged when the patient was 8 years and 3 months of age; the severity of submergence was greater when the patient was 9 years of age. The affected primary molar was considered to be ankylosed; it was extracted when the patient was 9 years and 4 months of age. Histopathological analysis of the tooth revealed disturbed cementum formation, which is a typical characteristic of teeth in patients with HPP. On the basis of these findings, we hypothesize that the disturbed cementum formation could lead to susceptibility to early exfoliation of anterior teeth, as well as occurrence of ankylosis involving posterior teeth.

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

ABSTRACT Objective: To test the hypothesis that mutations in the parathyroid hormone 1 receptor (PTH1R) include effects in both primary and permanent teeth. Materials and Methods: DNA was extracted from saliva samples of 29 patients (8 familial and 21 sporadic) who presented with clinical evidence of infraoccluded teeth, and their unaffected relatives (N = 22). Sequencing followed by mutational analysis of the coding regions of PTH1R gene was completed for all individuals (N = 29). Results: Eight of 29 cases revealed a heterozygous pathogenic variant in the PTH1R gene; five of eight variants represented distinct mutations based on comparison with the dbSNP, HGMD, and ESP databases. One mutation (c.1765 T&gt;C p.Trp89Arg) was found to segregate within a family (n = 3). In silico analyses for all variants revealed a putative pathogenic effect. A genotype-phenotype correlation was reported as defined by a functional mutation in PTH1R and corresponding effects on one or more posterior teeth only; unilateral or bilateral involvement, infraoccluded primary teeth. Conclusions: Novel mutations were reported in the PTH1R gene that included PFE-affected primary molars, thus providing the basis for using a genetic diagnostic tool for early diagnosis leading to proper management.

Hypodontia is characterized by partial or total congenital missing of one or more teeth, on one or both dentitions. Heredity is the main etiological factor and the principal clinical features are reduction on number, size and form of teeth, and late eruption. Removable partial prosthesis, fixed prosthesis, overdentures and adhesive prosthesis are alternative treatments, and the indication is type dependent. The aim of this study was to describe the clinical case of an eleven-year-old child with eight missing permanent teeth of idiopathic etiology.The patient had facial and skeletal symmetry, normal development and was not related to any syndrome. Clinical characteristics: permanent teeth with good periodontal conditions (16, 12, 11, 21, 22, 26, 36, 31, 42, 46), primary teeth (53, 63, 64, 73, 83); overbite and microdontia on teeth 12 and 22. The treatment plan was done initially by documenting of the case for teeth analysis (study casting models, periapicals and panoramic x-rays, and photographs), and followed by the exodontics of teeth 73 and 83.A removable appliance in autocured acrylic resin, using teeth in acrylic for maintenance of functional space and occlusion was planned and carried out.An anterior track for vertical dimension gain was used because of his accentuated overbite. The patient will be monitored until the end of the craniofacial growth, when it will be again evaluated and forwarded for the final oral rehabilitation. Hypodontia diagnosis and management should be performed as early as possible not to interfere with the craniofacial development of the child.

A four-year-old child was presented to the Pediatric Dentistry Clinic of the Federal University, 21 days after an incident in which canine first and second primary molar teeth were avulsed, due to a trauma to the face. This was confirmed on radiological examination. The clinical examinations showed that tissues were normal. A removable space-maintaining dental-mucosa supported appliance was made in acrylic resin to replace the three missing teeth. After a period of eight months, the tissues were preserved, the device is helping the child to eat, to speak, and preserving the appearance of the patient. Radiograph examinations have shown that the first molar tooth and canine, first pre molar and second pre molar teeth are erupting normally. Trauma in primary dentition can cause psychological,morphological and functional problems. In the presented case the treatment was planned to recuperate the function and to avoid problems from the premature loss of primary teeth.

Objective: This study was conducted to compare the efficacy of 3Mixtatin (a combination of simvastatin and 3Mix antibiotic) with MTA and Formocresol for the pulpotomy of primary molars. Study design: 114 children aged 3–6 years old with 150 primary molars were randomly allocated to three groups. MTA, Formocresol or 3Mixtatin were used for Pulpotomies. Hard setting zinc oxide eugenol was used to cover these materials. The teeth were restored with amalgam. Blinded radiographic and clinical examinations were conducted at 6, 12 and 24 months after treatment for the presence of pain, tenderness to palpation and percussion, sinus tract, swelling, presence of internal or external root resorption, inter-radicular radiolucency, and periapical lesion. Results: 122 teeth were available for 24-month follow-up study. The overall success rate was 78.9% for FC, 90.5% for 3Mixtatin and 88.1% for MTA group. There was no significant difference in overall success rate among the groups after 24-month follow-up (X2=2.43, df = 2, P =0.27). Conclusion: Our findings demonstrated remarkable results of 3Mixtatin in pulpotomy of primary teeth at the 24-month follow-up. Therefore, 3Mixtatin may be considered as an effective material in pulpotomy of primary teeth because of its successful results.

Aim: The aim of this study was to undertake a comprehensive quantitative investigation of pulpal blood flow (PBF) changes in human non-carious primary molar teeth with variable degrees of root resorption by Laser Doppler Flowmetry (LDF) and Pulse Oximetry (PO) methods. Materials and Methods: Data was collected from clinically and radiographically healthy 86 mandibular primary molars which have different physiological root resorption levels (PRRLs). PRRLs for each of the teeth were assessed using periapical radiographs and teeth were subdivided into three groups. Results: The LDF values demonstrated a significant difference (p = 0.0001) between all groups although PO did not demonstrate any difference (p = 0.109). Statistical analysis of LDF values demonstrated significant differences between Groups A and C (p = 0.0001) and Groups B and C (p = 0.008). Furthermore, positive correlations were determined between LDF values and PRRL groups (p = 0.0001) and patients' ages (p = 0.0001). Conclusions: In our study, it was observed that the PBF values of human primary molars measured by LDF tended to increase with the progress of physiological root resorption and age. LDF was found to be a more effective method than PO to assess the pulpal vascularity changes of human primary molars.
