Introduction: Age determination plays a great role in forensic medicine, pediatric endocrinology, and pedodontic treatment planning. It helps in the management of different types of malocclusion in relation to maxillofacial growth. The aim of the study was to determine the dental developmental stages in female population and to test the applicability of Demirjian’s and Nolla’s criteria for maturity scoring in dental age assessment. Materials and Methods: Orthopantomographs of 200 females of 8–16 years were taken and the dental age was calculated using the Demirjian’s and Nolla’s dental age estimation method. Chronological age was also recorded and correlated to the dental ages obtained. Results: A strong correlation was found between chronological and dental ages (P < 0.005). The intraclass correlation coefficient between the two methods showed excellent agreement between the two (P < 0.005). Conclusion: A positive high degree correlation noticed between chronological age, dental age, and both age estimation methods may thus be applicable to the female population in Cochin.

Aim: To evaluate and compare the efficacy of "calcium sucrose phosphate" (CaSP) toothpaste (Enafix 5%) with ordinarily used calcium, phosphate-containing toothpaste in elevating the level of calcium, phosphate ions in saliva. Secondary aims were to evaluate substantivity and plaque-reducing ability of CaSP toothpaste.

Materials and Methods: Thirty study participants of age group 6-13 years were divided into two groups: Group X (Control group) was made to continue brushing with their regularly used calcium, phosphate-containing toothpaste and Group Y (Test group) was allotted CaSP toothpaste. 1 ml of unstimulated saliva was periodically collected from both groups to determine any alteration in the salivary calcium, phosphate level. Parameters such as substantivity and plaque-reducing ability of CaSP toothpaste were also evaluated. Salivary mineral's intergroup comparison was evaluated by Student's -test while its intragroup comparison along with the plaque amount variation in Group Y was evaluated by ANOVA and Tukey's test.

Results: Group Y showed an increase in the salivary calcium level though not statistically significant. The increase was pronounced in samples collected on day 1. Group Y showed a consistent level of calcium, phosphate in samples collected immediately and 6 h postbrushing, indicating its substantivity. In addition, Group Y had an impact in reducing the plaque level when the 1-month plaque score was compared with the 12-month score.

Conclusion: CaSP leads to an increase in the salivary calcium level though it was not statistically significant. Supervised brushing and dietary habits showed a positive effect on both the groups. CaSP toothpaste also showed substantivity and plaque-reducing ability.

The number of deaf children has dramatically increased in the past few decades. These children present to the pediatric dentist a unique set of challenges mostly pertaining to the establishment of communication with them. There have been very few attempts in the past to break down these challenges and formulate a strategy on how to manage them effectively. This is a case report of a child who was successfully managed using two different modes of communication. Finally, the advantages and disadvantages are mentioned, and a common strategy incorporating the positives of both the methods has been devised.

PURPOSE: To compare the efficacy between supplementing ferrous fumarate and ferrous sulfate to carbonated beverages by recording the in vitro mineral loss and surface microhardness (SMH) changes in human enamel.

METHODS: 120 enamel blocks each (from primary and permanent teeth) were uniformly prepared and the initial SMH was recorded. These enamel specimens were equally divided (n = 60) for their respective beverage treatment in Group 1 (2 mmol/L ferrous sulfate) and Group 2 (2 mmol/L ferrous fumarate). Each group was further divided into three subgroups as Coca-Cola, Sprite and mineral water (n= 10). The specimens were subjected to three repetitive cycles of respective treatment for a 5-minute incubation period, equally interspaced by 5-minute storage in artificial saliva. The calcium and phosphate released after each cycle were analyzed spectrophotometrically and the final SMH recorded.

RESULTS: The results were tested using student's t-test, one-way ANOVA and Wilcoxon signed rank test (P < 0.05). The spectrophotometric assessment of calcium and phosphate withdrawal found more loss with the supplementation of 2 mmol/L ferrous sulfate than ferrous fumarate (P < 0.005). Similarly, the mean surface microhardness reduction was less with the supplementation of 2 mmol/L ferrous fumarate than with ferrous sulfate (P < 0.005). Statistical comparisons revealed the maximum surface microhardness and mineral loss with primary enamel and the maximum loss produced in all groups by Coca-Cola (P < 0.005).

Aim: To clinically and radiographically evaluate the reparative dentin formation in indirect pulp treatment (IPT) using mineral trioxide aggregate (MTA) and light cured calcium silicate (TheraCal) in primary molars over a period of 6 months. Materials and Methods: A clinical trial on IPT on 43 primary molars in 21 patients between the age of 4-7 years, divided into two groups: 22 teeth in MTA group and 21 in TheraCal group. Measurement of the variation in dentin thickness was done on the digitalized radiograph at baseline, 3 months and 6 months using CorelDRAW X3 software. Results: Statistical analysis using an independent t-test for intragroup and intergroup comparison showed a significant increase in dentin thickness in both the MTA and TheraCal group (intragroup comparison [P < 0.05]). However, intergroup comparison between MTA and TheraCal showed no statistical difference in reparative dentin formation (P > 0.05). Conclusion: Clinically and radiographically, both MTA and TheraCal are good IPT materials. The better handling characteristics and comparable reparative dentin-forming ability of TheraCal make this material an alternative to MTA in pediatric restorative procedures. © 2016 Contemporary Clinical Dentistry | Published by Wolters Kluwer - Medknow.

BACKGROUND: A manifold increase in the consumption of aerated beverages has witnessed a twin increase in tooth wear and raised demand for esthetic restorative materials. This study aimed to evaluate the surface microhardness changes of esthetic restorative materials following treatment with aerated beverages in an in-vitro situation.

MATERIAL AND METHODS: The initial surface microhardness of the restorative materials GC Fuji II LC, GC Fuji IX, Nano Glass ionomer, Resin and Nano composite was recorded. These materials were studied under 3 groups that included those exposed to the acidic beverages daily, weekly once in a month and those that had no exposures at all. The final surface microhardness of the materials was recorded following experimentation and was subjected to statistical comparisons.

RESULTS: The restorative materials were compared for their surface microhardness changes following respective treatments using the T-test and One-way ANOVA analysis. Inter-comparisons between the groups showed statistical significance (p<.05), when treated with both the beverages. The five restorative materials revealed surface microhardness loss; the maximum reduction noticed with the Nano glass ionomer cement tested (p<.0005).

CONCLUSIONS: The surface microhardness of restorative materials markedly reduced upon repeated exposures with acidic beverages; the product with phosphoric acid producing the maximum surface microhardness loss.

KEY WORDS: Restorative materials, acidic beverages, surface microhardness, resin composites, glass ionomers.

Background: The role of cytokines as a marker in the oral inflammatory process in ECC has not been fully explored before and after full mouth rehabilitation. Aims: The aim of this study was to assess the level of salivary interleukin-6 (IL-6) in children with ECC and to compare its levels before and after comprehensive full mouth rehabilitation. Methods and Materials: Saliva samples were collected from children with ECC prior to dental treatment and 3-month post treatment. The salivary IL-6 levels were analyzed using the ELISA method. The gingival index was also timely recorded. Oral health awareness sessions were conducted for children and their parents at regular intervals during the 3-month study period. Statistical analysis used: Wilcoxon Signed Rank test compared the levels of salivary IL-6 while, the paired t test compared the values of gingival index before and after treatment. Results: The mean level of salivary IL-6 before and 3 months after treatment had reduced and this reduction was statistically significant (P&lt; 0.000). The gingival index scores had also reduced significantly 3-months post treatment (P&lt; 0.002). Conclusions: Children with ECC when completely rehabilitated and kept under frequent follow up, which includes reinforcement of oral hygiene measures and maintaining a low caries activity state, the level of inflammation (IL-6) can definitely be minimized and thereby improving the quality of life of affected children. © 2016 Contemporary Clinical Dentistry.

Objectives: Clinical and radiographic effects of mineral trioxide aggregate (white MTA) and calcium hydroxide (Dycal) in indirect pulp treatment (IPT) of primary teeth over a period of 6 months. Materials and Methods: A clinical trial with sample size of 40 primary molars between the age group of 5-9 years, of which, 20 teeth were considered, each for MTA and Dycal. Measurements on the digitized radiographs were performed at baseline, third and sixth month, increase in dentin was then measured using Corel Draw software. Result: Independent t-test had indicated that at the end of 3 months and 6 months, a statistically significant increase in dentin thickness with both MTA and Dycal (P-value ≤ 0.001) was found. Within the MTA group, the thickness of dentin formed was 0.089 mm ± 0.031 mm at first 3 months and 0.055 ± 0.022 mm at the second 3 months, (P ≤ 0.001) evaluated using paired t-test. In the Dycal group, increment in dentin deposited was 0.068 mm at the first 3 months and second 3 months, it was 0.030 mm (P-value ≤ 0.001). Conclusion: Clinically and radiographically, MTA is superior to Dycal as a good IPT medicament in primary teeth.

Choanal atresia is a rare cryptic congenital anomaly with developmental failure of the nasal cavity to communicate with the nasophaynx, resulting in a significant physiological and anatomical alteration of the dento-facial complex. It is considered as a life-threatening or lethal congenital malformation in an obligatory nasal breathing neonate. Elective transnasal endoscopic repair is the most preferred and minimally invasive procedure to correct this anomaly. This case report describes the multi-disciplinary team approach that included pedodontists to manage the case of a 6-month-old infant with choanal atresia suffering from breathlessness, feeding difficulty, and disturbed sleep.

OBJECTIVES: This study aimed to compare the in vitro mineral loss and surface microhardness (SMH) changes in human enamel specimens following supplementation of acidic carbonated beverages with low iron concentrations than when treated without. STUDY DESIGN: 180 enamel blocks each from primary and permanent teeth were prepared and equally subdivided (n=10) for their respective treatments in Group 1 (Coca Cola and Sprite without iron supplementation) and Group 2 (beverages supplemented with 2/5 mmol/L FeSO₄.7H₂O). Following initial SMH estimation, the blocks were subjected to 3 treatment cycles of 5/20 minute incubation periods, equally interspaced by a 5-min treatment in artificial saliva. The calcium and phosphate released after each cycle were analyzed spectrophotometrically and the final SMH was recorded. The results were tested using student's T test, One-way ANOVA and Kruskal Walli's test (p&lt;0.05). RESULTS: Two and five mmol/L FeSO₄.7H₂O supplementation produced a highly significant SMH change and calcium and phosphate reduction than when treated without (p&lt;.0005). Both the enamel specimens showed similar patterns of mineral loss and SMH reduction, with pronounced effects in the twenty minute incubation cycles. CONCLUSION: Our results suggest that 2 mmol/L FeSO₄.7H₂O supplementation to acidic beverages is beneficial in reducing mineral loss and preserving surface microhardness of human enamel.

The systemic condition of patients with kidney failure has oral manifestations and specific implications for dental treatment. Few segments of the population need dental services as desperately as do patients receiving hemodialysis or kidney transplants. In this ever increasing group of patients, dental disease may have consequences much more serious than the loss of function, esthetics, and comfort. Dental problems may compromise the patient's general health and hinder medical efforts to either maintain or replace vital kidney functions. Specifically, the dentist must consider bleeding tendency, risk of infection and medications before treating the patient. Oral and dental health has served as a valuable indicator in measuring the prognosis of chronic kidney disease, while, its role in diagnosing renal pathosis requires to be explored further. This manuscript reviews pertinent information to help medical and dental professionals systematically treat patients who exhibit oral and systemic manifestations of renal disease, from the onset of renal impairment through hemodialysis.

The balance between free radical production and antioxidant defenses in the body has important systemic and oral health implications. There is convincing evidence that breastmilk containing antioxidants is important in the prevention of diseases in infancy. This study compared the total antioxidant concentration of human breastmilk expressed at different stages of lactation, stored at various temperatures and durations. Expressed breastmilk (EBM) samples of the third, seventh and 30th day were collected from women who had term and preterm deliveries (n=20). Another cohort of women (n=20) was also assessed; these women were more than five months postpartum and lactating. The total antioxidant capacity (TAC) of EBM was assessed at zero hours at room temperature, at 48 hours, one week post-refrigeration (4 °C), and freezing (-8 °C) respectively using the phosphomolybdenum method. The highest antioxidant levels were found in colostrum. The TAC of EBM reduced with time and at post-refrigeration and after freezing (p<0.0005). No significant difference in the mean TAC was observed between the EBM samples obtained from women with either term or preterm deliveries. The progressive loss of antioxidant content of EBM emphasizes the need of awareness and curtailment of the practice of storing and later use of EBM. © International Centre for Diarrhoeal Disease Research, Bangladesh.
