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.

N. Renahan, Dr. Balagopal Varma R., Parvathy Kumaran, and Arun Mamachan Xavier, “Unique Approach to Dental Management of Children with Hearing Impairment.”, Int J Clin Pediatr Dent, vol. 10, no. 1, pp. 107-110, 2017.[Abstract]

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.

Navya P. Menon, Dr. Balagopal Varma R., Janardhanan, S., Parvathy Kumaran, Arun Mamachan Xavier, and Bhat Sangeetha Govinda, “Clinical and radiographic comparison of indirect pulp treatment using light-cured calcium silicate and mineral trioxide aggregate in primary molars: A randomized clinical trial”, Contemporary Clinical Dentistry, vol. 7, pp. 475-480, 2016.[Abstract]

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.

Bhat, Arun Mamachan Xavier, and Suresh Kumar J., “Evaluation of salivary interleukin-6 in children with early childhood caries after treatment”, Contemporary Clinical Dentistry, vol. 7, pp. 198-202, 2016.[Abstract]

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.

Treacher Collins syndrome (TCS) or Franceschetti syndrome is an autosomal dominant disorder of craniofacial development with variable phenotypic expression. It presents with characteristic facial appearance enabling it to be easily recognizable. A case of a 10-year-old girl having TCS is briefly described in this article. A review of the etiology, clinical features, differential diagnosis, and treatment options are also discussed. More »»

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.
