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.

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.

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: To evaluate the clinical and radiographic outcomes (24 months) of indirect pulp treatment (IPT)in primary teeth when a self-etching primer or a calcium hydroxide layer was used over the remaining carious dentin. Study design: Primary molar teeth with deep carious lesions without signs and symptoms of irreversible pulpitis were divided into two groups, according to the capping material: Experimental group(1): self-etching adhesive system (Clearfill SE Bond); and Control group (2): calcium hydroxide liner(Dycal). Both groups were followed up after application of a resin restoration (3M - Z250). Results: After 2 years of clinical and radiographic follow-up, no statistical difference was found between groups (p=1). The overall success rate reached 87%. Conclusion: These results demonstrate that IPT has a high clinical and radiographic performance in primary teeth and is not dependent on the capping material used over the demineralized dentin.

Aim: The aim of the present study was to clinically and radiographically evaluate Mineral Trioxide Aggre-gate (MTA) as an agent for pulpotomy in primary teeth and to compare it with that of Formocresol (FC) pulpotomy. Method: Seventy first and second primary mandibular molars of children were chosen on patients who required minimum two pulpotomies in either arch or same arch. After the standardized technique of Pulpotomy with MTA and Formocresol, all molars were treated with a thick mix of Zinc oxide Eugenol cement into the coronal pulp chamber followed by preformed stainless steel crown. The children were followed up for clinical and radio graphical examination after 6,12 and 24 month for Pain, Swelling, Sinus/ fistula, Periapical changes, Furcation radiolucency and internal resorption. Results: MTA represents 97% clinical success rate in comparison to Formocresol with 85% success. Radiographically also MTA showed more promising results with 88.6% success in comparison to Formocresol with 54.3%. Conclusions: Thus, MTA pulpotomy has emerged as an easier line of treatment to save the premature loss of primary teeth due to caries or trauma.

Ankylosis is a condition frequently associated with primary molars, wherein the ankylosed primary teeth remain in a fixed position, while the adjacent teeth continue to erupt, moving occlusally. In this case report, a five-year-old boy, who had a retained and submerged left lower second primary molar, was presented. Luxation of ankylosed primary molar was considered as a treatment approach. After four months, the tooth erupted to the occlusal level, and there was evidence of further development of a permanent successor in radiographic evaluation. After one year, tooth mobility, bone formation, and development of a permanent successor were in good condition.

Objective: The present study determined whether primary molar pulpotomies showed equal in vitro and clinical success when restored with sandwich restoration with a bulk-fill flowable composite (BFRBC) liner versus a stainless steel crown (SSC) restoration. Study design: Sixty extracted human primary second molars with proximo-occlusal cavities were selected for in vitro test. The specimens were randomly divided into three groups (n = 20) and restored with sandwich restoration with a BFRBC liner, composite (RBC) restoration and SSC. In addition, sixty teeth were selected from 20 children and each child had at least three primary molars (first and/or second primary molar) requiring pulpotomy. The patients were recalled for clinical and radiographic evaluation at approximately 6- and 12-month intervals. Results: The SSC restoration had significantly higher microleakage than the others. Although there was a significant difference between the RBC and the SSC (P = 0.02), the differences between the BFRBC and the RBC, as well as between the BFRBC and the SSC, were not statistically significant at the 12-month radiographic evaluation (P = 0.33 and P = 0.11, respectively). Conclusion: In laboratory conditions, sandwich restoration with BFRBC liner showed a superior seal margins of pulpotomized primary molars. Based clinical and radiographical evaluation, teeth treated with formocresol pulpotomy and restored with sandwich restoration with BFRBC liner were as successful as those restored with a SSC.

Abstract Objectives To investigate the factors influencing primary tooth survival after pulpectomy and to elucidate age-related morphological changes in the root canal of primary molars. Materials and Methods This retrospective study included 592 primary anterior teeth and 583 primary molars after pulpectomy. Survival analysis was performed to determine the predictors of pulpectomy failure. Cone-beam computed tomography (CBCT) data of the maxillary first primary teeth from 63 children aged 3–8 years were collected, and Spearman’s correlation and binary logistic regression were performed to assess age-related changes in canal morphology. Results Periapical periodontitis, Vitapex® filling, and non-general anesthesia treatment increased the failure risk of anterior primary teeth pulpectomy. Older age at treatment increased the primary molar pulpectomy failure risk. On CBCT analysis, the ratio of canal length to root length for the mesiobuccal (MB), distobuccal (DB), and palatal (P) roots negatively correlated with age (P<0.05). The ratio between the root canal wall area with inner diameter lesser than 0.15 mm and the whole root canal wall area (R.15) at plane D of the MB canals positively correlated with age (P<0.05). The number of discontinuous canals (Ndis) for the MB and DB roots increased with age and the canal area at plane D for MB and P canals negatively correlated with age (P<0.05). Conclusions Older age at treatment for primary molar pulpectomy and periapical lesions, non-general anesthesia treatment, and Vitapex® filling for anterior primary teeth pulpectomy may predict a higher failure risk. Age-related morphological changes in the primary molar root canal were evident and could be a reason for treatment failure.

Hydroxyapatite Crystals

Aim: To clinically and radiographically evaluate the potential of bioactive glass and hydroxyapatite crystals as pulpotomy agents in primary molars. Methods: A total of fifty teeth were selected from 25 children (14 boys and 11 girls) aged 4 to 9 years, who had no medical condition that would contraindicate pulp therapy. Each child had at least two primary molars (first and/or second primary molar) requiring pulpotomy. A conventional pulpotomy procedure was performed on the selected teeth using bioactive glass and hydroxyapatite crystals. All molars were evaluated clinically and radiographically at regular intervals over 12 months. The results were subjected to statistical analysis using Fischer exact test. Results: One hundred percent clinical success and 84% radiographic success was observed in both the groups at the end of the study period. Conclusions: The study concluded that both bioactive glass and hydroxyapatite crystals can be used as pulpotomy agents in primary molars.
