S Mukhopadhyay
January-March 2011, 29(1):34-38
DOI:10.4103/0970-4388.79928  PMID:21521916
Background: A mesiodens is a supernumerary tooth located in the palatal midline between the two maxillary central incisors. The overall prevalence varies between 0.15 and 1.9%. The present study aimed to evaluate the epidemiological characteristics of mesiodens in the pediatric population. Materials and Methods: A longitudinal prospective study was carried out in 7932 children to determine the prevalence of mesiodens. The following data were also recorded: age, sex, shape, sagittal position, orientation, eruption status, number and complications caused by mesiodens. Results: The prevalence of mesiodens in the present study was 0.8%. The sex ratio was 1.78:1, favoring boys. The majority of mesiodens (67.9%) were conical in shape, followed by the supplemental (17.9) and tuberculate (14.1%) types. 71.8% of the mesiodens were palatally placed, 25.6% erupted on the arch and 2.6% were labially positioned. A majority of the mesiodens (62.8%) were vertically aligned. Inverted and horizontal positions were observed in 30.8% and 6.4% of the cases. Most of the mesiodens (53.8%) were impacted, and 14 children had two mesiodens. Most of the mesiodens were associated with complications, and only 26.9% were asymptomatic. Conclusions: The prevalence of mesiodens was 0.8% .Conical shape, palatal position and vertical orientation were common characteristic observations in the study.

K-file vs ProFiles in cleaning capacity and instrumentation time in primary molar root canals: An in vitro study
N Madan, A Rathnam, AL Shigli, KR Indushekar
January-March 2011, 29(1):2-6
DOI:10.4103/0970-4388.79907  PMID:21521910
Objectives: This study compares the efficiency of manual K-files and rotary ProFiles in cleaning capacity and instrumentation time in primary molar root canals. Materials and Methods: Seventy-five maxillary and mandibular primary molar root canals were instrumented with ProFiles and K-files in the step-back manner from size #10 to #40. The teeth were decalcified, dehydrated and cleared, and analyzed for the presence of dye remaining on the root canal walls, which served as an evidence of cleaning capacity of both the techniques. Results: The results showed a significant difference in the cleaning capacity of the root canals with ProFiles and K-files, in apical and coronal thirds of the root canal. ProFiles have been found to be more efficient in cleaning the coronal thirds and K-files in cleaning apical thirds of the root canals. Both the techniques were almost equally effective in cleaning the middle thirds of the canals. The time taken during the cleaning of the root canals appeared to be statistically shorter with K-files than profiles.

N Manuja, IK Pandit, N Srivastava, N Gugnani, R Nagpal
January-March 2011, 29(1):7-13
DOI:10.4103/0970-4388.79913  PMID:21521911
Aim: To comparatively evaluate the shear bond strength of recent tooth-colored restorative materials to dentin. Materials and Methods: Flat dentinal surface were prepared from 60 caries free, extracted human permanent molars and were mounted in acrylic rings. These were randomly divided into four groups - Group A to Group D, according to the restorative material used i.e. Glass ionomer cement (Fuji IX), Giomer (Beautifil), an Ormocer-based composite (Admira) and Nano Ceramic restorative material (Ceram X). These restorative materials were applied on dentinal surface of all the specimens using nylon cylinders. The mounted samples were stored in distilled water for 24 hours and thermocycled. They were then subjected to shear bond strength test using universal testing machine. Data was analyzed using a one-way analysis of variance (ANOVA) and student's 't'-test. Results: Ceram X (16.63±0.94 MPa) and Admira (17.31±0.95 MPa) were comparable in their bond strength values, but depicted significantly higher bond strength when compared to Beautifil (12.39±1.05 MPa) and Fuji IX (7.76±1.07 MPa). Conclusion: Nano-ceramic and ormocer-based restorative materials showed better bonding potential to dentin as compared to GIC and Giomer.

Nanoionomer: Evaluation of microleakage
S Upadhyay, A Rao
January-March 2011, 29(1):20-24
DOI:10.4103/0970-4388.79919  PMID:21521913
Background: Glass ionomer cements are widely used in pediatric practice due to their advantage of fluoride release and chemical bond to tooth structure. Adherence of the restorative material to the cavity walls is one of the most important characteristic for it to be proven as an ideal material as it prevents microleakage. Aims and Objectives: This study was aimed at evaluating the microleakage of nanofilled resin-modified glass ionomer cement compared with the conventional and resin-modified glass ionomer cements. Materials and Methods: Standard class V cavities of size 3 mm x 2 mm x 2 mm were made on a total of 30 extracted teeth and restored with the conventional glass ionomer, resin-modified glass ionomer or nanoionomer. After thermocycling, teeth were immersed in 0.5% methylene blue dye for 24 h. They were then sectioned buccolingually. Microleakage was assessed for the occlusal and gingival walls using a compound microscope by two examiners independently. Results: Nanoionomer demonstrated the least microleakage, with a mean score of 1.3, compared with the resin-modified glass ionomer (score of 3.2) and conventional glass ionomer cement (score 2.6). Conclusion: Nanoionomer exhibited adequate resistance to microleakage and thus may prove better than conventional or resin-modified glass ionomers.

MN Shahani, VV Subba Reddy
January-March 2011, 29(1):28-33
DOI:10.4103/0970-4388.79925  PMID:21521915
Disinfection of the root canal system is one of the primary aims of root canal treatment. This can be achieved through the use of various antimicrobial agents in the form of irrigants and medicaments. The antimicrobial substantivity of 2% chlorhexidine gluconate, 1% povidone iodine, 2.5% hydrogen peroxide followed by 2% sodium hypochlorite, and 2% sodium hypochlorite alone as irrigants was assessed in instrumented root canals. 2% chlorhexidine showed antimicrobial substantivity lasting up to 72 h, followed by 1% povidone iodine, and 2% sodium hypochlorite. Thus 2% chlorhexidine should be used as a final rinse irrigant in endodontic treatment protocols.

KS Dhull, B Nandlal
January-March 2011, 29(1):39-45
DOI:10.4103/0970-4388.79930  PMID:21521917
Aims and Objective: To determine the effect of low-concentration daily topical fluoride application on fluoride release of Giomer and Compomer and to compare the amount of fluoride release from Giomer to that of Compomer. Materials and Methods: Forty-eight specimens of each Giomer and Compomer were divided into four treatment groups, namely, control group, fluoridated dentifrice (500 ppm) once-daily group, fluoridated dentifrice (500 ppm) twice-daily group and fluoridated dentifrice (500 ppm) once-daily + fluoridated mouthwash (225 ppm) group. Each specimen was suspended in demineralising solution for 6 h and remineralising solution for 18 h. Fluoride release was measured in both the demineralising solution and the remineralising solution daily for 21 days. Total daily fluoride release for each specimen was calculated by adding the amount released in the demineralising solution to that released in the remineralising solution. Results and Conclusion: The fluoride release (ppm) was found to be higher in Giomer when compared with Compomer. The fluoride released from Giomer and Compomer was significantly higher in the acidic demineralising solution than in the neutral remineralising solution. It was found that increasing fluoride exposure significantly increased fluoride release from Giomer and Compomer. It was found that the fluoride release from the subgroups of Giomer and Compomer was in the following order: fluoridated dentifrice twice-daily > fluoridated dentifrice once-daily + fluoridated mouthwash > fluoridated dentifrice once-daily > control group. It was found that Giomer showed a greater fluoride uptake Compomer.

January-March 2011, 29(1):14-19
DOI:10.4103/0970-4388.79915  PMID:21521912
Objective: The present study was conducted to evaluate, on a longitudinal basis, the changes in intercanine and intermolar widths form the primary to the early mixed dentition periods. Materials and Methods: A total of 38 children aged 4-5 years, with normal occlusion without any proximal caries or any dental anomalies, were selected. The impressions were recorded and casts were prepared. Intercanine and intermolar widths were measured on these dental casts with the help of a digital vernier calliper. After 3 years follow-up, the impressions were recorded again and dental casts were prepared. Intercanine and intermolar widths were measured again at this stage and were compared with the baseline data using the paired t-test and the chi square test. Results: There is a significant increase in the intercanine (3.93 + 1.70 mm) and intermolar width (1.49 + 1.77 mm) during the transition period from primary to early mixed dentition in both the arches and both the sexes. The gender-wise comparison showed a greater increase in males than in females, but this was not statistically significant. Conclusion: A thorough knowledge of growth changes during various stages of the mixed dentition period are important for a pediatric dentist to make an accurate diagnosis and treatment planning during preventive and interceptive orthodontics.

SNMP Sockalingam
January-March 2011, 29(1):53-56
DOI:10.4103/0970-4388.79938  PMID:21521920
Amelogenesis imperfecta represents a group of dental developmental conditions that are genomic in origin. Hypoplastic AI, hypomineralised AI or both in combination were the most common types seen clinically. This paper describes oral rehabilitation of a 9-year-old Malay girl with inherited hypoplastic AI using transparent thermoforming templates. The defective surface areas were reconstructed to their original dimensions on stone cast models of the upper and lower arches using composite, and transparent thermoform templates were fabricated on the models. The templates were used as crown formers to reconstruct the defective teeth clinically using esthetically matching composite. The usage of the templates allowed direct light curing of the composite, accurate reproducibility of the anatomic contours of the defective teeth, reduced chair-side time and easy contouring and placement of homogenous thickness of composite in otherwise inaccessible sites of the affected teeth.

R Rayen, VS Hariharan, N Elavazhagan, N Kamalendran, R Varadarajan
January-March 2011, 29(1):74-79
DOI:10.4103/0970-4388.79954  PMID:21521925
Hemophilia is the most common inherited bleeding disorder. Hemophilic patients should be cosidered as special patients. There is no contraindication to general dental treatment for hemophiliacs, as they generally do not involve bleeding. But caution must be used with any surgical procedures that involve the local and general anesthesia. Such patients should always be managed in the setting of specialized units with appropriate clinical expertise and laboratory support. Recent advances in the management of hemophilia have enabled many hemophiliac patients to receive surgical dental procedures in an outpatient dental care on a routine basis. The purpose of this case report is to provide a few management strategies when providing full mouth rehabilitation under anesthesia and replacement therapies that are available. In addition, overviews of possible complication that may be encountered when providing such treatment are discussed here.
