Conservative management of large radicular cysts associated with non-vital primary teeth: A case series and literature review
No full textRadicular cysts are the most common odontogenic cystic lesions of inflammatory origin. Large radicular cyst is comparatively less frequently associated with primary teeth. They represent only 0.5-3.3% of the total number of cysts in primary dentition. Radicular cysts arising from deciduous teeth are reported to occur in age range of 3-19 years with a male predominance. Although large radicular cysts are treated by enucleation with extensive removal of bone and vital teeth, marsupialization can be preferred as a conservative approach to reduce the morbidity. The purpose of this article is to report a case series of large radicular cysts associated with badly mutilated and traumatized primary teeth and to demonstrate how best they can be conservatively treated during mixed dentition period

Evaluation of enamel remineralizing potential of self-assembling peptide P11-4 on artificially induced enamel lesions in vitro
No full textPurpose: The purpose of this study was to evaluate the remineralizing efficacy of self-assembling peptide (SAP) P11-4 qualitatively and quantitatively using scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX), respectively. Methodology: Enamel samples (n = 24) were prepared by sectioning extracted premolars and subjected for demineralization to create artificial enamel lesions. The structural and elemental concentrations (calcium and phosphate weight %) were assessed to obtain baseline data using SEM and EDX spectroscopy, respectively. The samples were randomly allocated into two groups and were treated with SAP P11-4 (test group) and casein phosphopeptides-amorphous calcium phosphate (CPP-ACP) (control group) followed by storage in artificial saliva to evaluate the remineralizing efficacy at 1-week, 1-month, and 3-month intervals. Results: Data were analyzed using the ANOVA and unpaired t-test. From the observed results, CPP-ACP showed a significant increase in Ca: P ratio (2.04 ± 0.2) with irregular surface calcific deposition at 1-week interval and this reduced with time (1.87 ± 0.11 at 3-month interval). Whereas P11-4 showed a significant increase in Ca: P ratio (1.95 ± 0.10) with uniform ion deposition suggestive of hydroxyapatite nucleation over a 3-month period. Conclusion: SAP P11-4 exhibited superior remineralization with uniform mineral deposition compared to CPP-ACP at 3-month interval
Orthodontic uprighting of impacted mandibular permanent second molar: A case report
No full textThe mandibular second molars can become impacted beneath the crown of the first molars due to various causes and fail to erupt normally. Presented herewith is a case report of orthodontic uprighting of a mesioangular impacted mandibular right permanent second molar. Though various treatment options were available, an uprighting push spring appliance was used as it is easy to fabricate and produces distal tipping and uprighting of the impacted tooth without the necessity of surgical assistance, bone removal, or splinting. The uprighting of the mandibular second molar was achieved within two months
Comparison of middle phalanx of the middle finger and cervical vertebrae as skeletal maturity indicators
No full textObjectives: To investigate the relationship between chronological age and the stages of maturation of cervical vertebrae maturation index (CVMI) and the middle phalanx of the middle finger (MP3) and to determine the correlation between CVMI and MP3. Materials and Methods: A cross-sectional study included 100 children (boys - 50, girls - 50) aged 8–14 years based on nonprobability quota sampling. The study included digital radiographs of the MP3 of the right hand and conventional lateral cephalograms. Chronological age was assessed by the date of birth, MP3 maturation by Rajagopal and Kansal's criteria, and CVMI development by Hassel and Farman's method. Statistical Analysis: Spearman's rank-order correlation coefficient was applied to measure the association between stages of MP3 and CVMI. Results: Progressive stages of MP3 and CVMI were seen as chronological age advanced. Girls showed an advanced trend than boys in both MP3 and CVMI stages. MP3 and CVMI stages showed a strong positive correlation (r + 0.836, P < 0.01). Conclusions: MP3 and CVMI both are equally good indicators of skeletal maturity. Assessment of skeletal maturity on lateral cephalogram (CVMI) is advantageous as it avoids the need for an additional radiograph

No full textEvaluation of dentin remineralization with zinc oxide and calcium fluoride nanoparticles – An In vitro study
No full textBackground: Partially demineralized dentin is remineralizable when mineral ions are made available in the near vicinity. Nanoparticles (NPs) have wide applications in remineralization process. Zinc promotes remineralization and has a synergistic effect when combined with fluoride. Hence, zinc oxide and calcium fluoride NPs were considered for dentin remineralization. Aim: The aim of this study was to evaluate the remineralizing ability of zinc oxide and calcium fluoride NPs on demineralized dentin individually and in combined form. Settings and Design: This was an in vitro study. Materials and Methods: Forty-eight dentin disks were prepared from the crowns of 12 extracted human molars and were allocated into four groups of 12 each, i.e., Group I – nano zinc oxide (nZnO), Group II – nano calcium fluoride (nCaF2), Group III – combined group (nZnO + nCaF2), and Group IV – artificial saliva (AS, control group). The specimens were demineralized with 37% phosphoric acid and placed in the respective remineralizing solutions for 24 h and 1 month. Calcium (Ca) and phosphorous (P) uptake was measured using energy-dispersive X-ray spectrometry, and structural changes were analyzed using scanning electron microscopy (SEM). Statistical Analysis: One-way analysis of variance, Student's t-test, and post hoc Tukey's test were used for statistical analysis. Results: At 1-month interval, all the groups showed an increase in Ca/P ratio, with highest being the combined group (4.24), followed by nCaF2 (3.30), nZnO (1.71), and AS (1.31) groups, and these differences were statistically significant (P = 0.000). On SEM analysis of dentinal samples at 1 month, depositions were evident in intertubular regions, wherein the highest deposits were observed in the nZnO group, followed by nZnO + nCaF2 and nCaF2 groups. Conclusion: Dentin samples subjected to remineralization with aqueous solutions of nZnO and nCaF2 showed an increase in calcium and phosphorous uptake and also dense granular depositions were evident in intertubular regions of dentin
Evaluation of caries arresting potential of silver diamine fluoride and sodium fluoride varnish in primary molars: A randomized controlled trial
No full textBackground: Caries management in the modern era has shifted away from the traditional surgical method toward a medical paradigm, which often includes fluoride therapy. Fluoride used in various forms has been proven to be effective in dental caries prevention. Silver diamine fluoride (SDF) and sodium fluoride (NaF) varnish are effective in arresting caries in primary molars. Aim: This study aimed to evaluate the effectiveness of 38% SDF and 5% NaF varnish in arresting caries in primary molars. Settings and Design: This study was a split-mouth randomized controlled trial. Materials and Methods: The randomized controlled trial comprised 34 children aged 6–9 years with teeth having caries in both right and left primary molars without pulpal involvement. Teeth were randomly allocated into two groups. In Group 1 (n = 34), 38% SDF + potassium iodide was applied and in Group 2 (n = 34), 5% NaF varnish was applied. The second application was done after 6 months in both groups. Children were recalled at 6- and 12-month intervals and evaluated for caries arrest. Statistical Analysis: Chi-square test was used to analyze the data. Results: Caries arresting potential was found to be higher in the SDF group compared to the NaF varnish group at both 6-month (SDF – 82% and NaF varnish – 45%) and 12-month intervals (SDF – 77% and NaF varnish – 42%) and the difference was found to be statistically significant (P = 0.002 and 0.004, respectively). Conclusion: SDF was more effective in arresting dental caries in primary molars compared to 5% NaF varnish
Impact of verbal, braille text, and tactile oral hygiene awareness instructions on oral health status of visually impaired children
No full textBackground: Visually impaired children face limitations in interacting with the environment, as they cannot see the facial expression of parents, teachers and cannot perceive social behavior. These children are challenged every day in learning basic life skills and maintenance of oral hygiene being one among them. Aim: To evaluate the impact of verbal, braille text, and tactile oral hygiene awareness instructions on oral health status of visually impaired children. Materials and Methods: One hundred and twenty institutionalized visually impaired children aged 6-16 years were selected and divided into three groups (40 children each). Group I: Verbal and tactile, Group II: Verbal and braille, Group III: Verbal, braille, and tactile. Instructions regarding maintenance of good oral hygiene and brushing technique were explained to all the children, and oral health status of these children using plaque index (Silness and Loe) and gingival index (Loe and Silness) was evaluated at 1, 3, and 6 months interval. Statistical Analysis: ANOVA test was used to analyze the intra- and inter-group comparisons and Tukey post-hoc test for multiple group comparisons. Results: Children in all the groups showed reduction in plaque and gingival scores. There was the highest percentage of reduction in plaque scores in Group III (70.6%), and the decrease in gingival scores was the highest in Group II (84%). Conclusion: Severity of dental plaque and gingivitis in visually impaired individuals can be reduced by a controlled and supervised educational program. The combination of all three, i.e., verbal, braille, and tactile mode of oral health educational aids proved to be effective
In vivo comparison of cavity disinfection efficacy with APF gel, Propolis, Diode Laser, and 2% chlorhexidine in primary teeth
No full textBackground: The survival of atraumatic restorative treatment (ART) restorations would be enhanced if near total elimination of cariogenic microorganisms could be done in the process of cavity cleaning before placing a restoration. Thus, use of disinfecting agents for achieving this goal could herald a new beginning in the field of contemporary dentistry. Aim: To assess and compare the cavity disinfection efficacy of APF gel, Brazilian Propolis, Diode Laser, and 2% chlorhexidine (CHX). Materials and Methods: The study was a randomized, single blinded, parallel grouped, active controlled trial. Eighty primary molars in 68 children with cavitated dentinal occlusal caries were randomly assigned into four groups (20 teeth each) Group I: APF gel; Group II: Propolis; Group III: Diode Laser, and Group IV: 2% CHX (control). After cavity preparation using ART procedure, dentinal samples collected before and after disinfection with respective agent of the group. These samples were subjected to microbiological evaluation, for total viable count (TVC) on blood agar, Streptococcus mutans on mutans-sanguis (MS) agar, and Lactobacilli (LB) on Rogosa agar. Results: Intragroup comparison (Wilcoxon signed rank test) showed significant reductions in TVC, MS, and LB counts in all the groups. Pairwise Mann–Whitney test showed APF gel had least bacterial reductions among the agents tested. Conclusion: This study illustrated the need for cavity disinfection. Diode Laser and Brazilian Propolis are equally effective as 2% CHX in cavity disinfection
