A comparison of various minimally invasive techniques for the removal of dental fluorosis stains in children.

CONTEXT: Dental fluorosis is caused by successive exposure to high concentrations of fluoride during tooth development leading to enamel with lower mineral content and increased porosity. AIMS: The aim of the study was to evaluate and compare the effectiveness of minimally invasive techniques for the removal of dental fluorosis stains in children in vivo. DESIGN: Ninety children in the age group of 10-17 years were selected. MATERIALS AND METHODS: The study sample was equally and randomly divided into three groups; Group 1: In-office bleaching with 35% hydrogen peroxide (HP) activated by light-emitting diode (LED) bleaching unit (35% HP), Group 2: Enamel microabrasion (EM) followed by in-office bleaching with 44% carbamide peroxide gel (EM), Group 3: In-office bleaching with 5% sodium hypochlorite (5% NaOCl). Statistical analysis was done using one-way ANOVA test. RESULTS: Bleaching with 35% HP activated by LED bleaching unit and EM followed by bleaching with 44% carbamide peroxide were equally effective for the removal of dental fluorosis stains in children in vivo. However, bleaching with 5% NaOCl could not completely remove moderate to severe stains. It was effective in removing only mild stains. Bleaching and microabrasion procedures caused slight decrease in tooth sensitivity readings by electric pulp vitality tester which continued to increase over time. However, none of the patients reported sensitivity in their teeth at any point of time. Patients were highly satisfied with the treatment outcome postoperatively but reported slight relapse of color in the three groups. CONCLUSIONS: Bleaching and microabrasion techniques can consider as an interesting alternatives to conventional operative treatment options.

Association of severe early childhood caries with iron deficiency anemia.

BACKGROUND: Severe tooth decay is known to affect the health and well-being of young children. However, there has been minimal research showing the association of severe early childhood caries (S-ECC) and iron deficiency anemia (IDA). AIMS: The primary aim of this study was to investigate an association between S-ECC with IDA. The secondary objective was to find an association between severe caries and body weight of the child. The oral health-related quality of life of children with S-ECC was also assessed. MATERIALS AND METHODS: Following the ethical approval, 60 children aged 2-6 years (30 with S-ECC and 30 controls with caries status <2) were recruited for this cross-sectional association study. Each child received a clinical examination for dental caries status using deft index and a blood investigation to determine various parameters; hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration, and packed cell volume (PCV). Children underwent venipuncture after due parental consent, and 2.5 mL blood was collected from each child to evaluate the above parameters. Following this, the parents filled up a 10 point questionnaire to determine the child's quality of life. Data were then analyzed by t-test and Fischer's exact t-test. RESULT: On comparison of percentage of children with IDA in S-ECC and control group, it was found that children with S-ECC were more likely to have IDA odds ratio (95% confidence interval): 10.77 (2.0, 104.9), (P = 0.001). In addition to this, S-ECC children were significantly more likely to have low Hb, MCV, and PCV levels (P < 0.001) which imply that S-ECC may be a risk marker for the development of anemia. More children (93%) with severe caries were found to have less body weight than ICMR standard weight for age as compared to children with low caries (P < 0.05%). CONCLUSION: S-ECC is strongly associated with the anemia due to iron deficiency, and efforts should be made toward the preventive and curative aspects of ECC, which may improve the general well-being and quality of life of a child.

Natal tooth associated with fibrous hyperplasia - a rare case report.

Eruption of tooth at about 6 months of age is a significant stage in child's life and is an emotional event for parents. However, a tooth present in the oral cavity of newborn can lead to a lot of delusions. Natal and neonatal teeth are of utmost importance not only for a dentist but also for a paediatrician due to parent's anxiety, folklore superstitions and numerous associated complications with it. This paper reports a rare case, wherein a natal tooth has led to the development of a reactive fibrous hyperplasia in an 8-week-old infant.

Repair for congenital macrostomia: vermilion square flap method.

Transverse facial clefts (macrostomia) are rare disorders that result when the embryonic mandibular and maxillary processes of the first branchial arch fail to fuse due to failure of mesodermal migration and merging to obliterate the embryonic grooves between the maxillary and mandibular processes to form the angle of the mouth at its normal anatomic position. Macrostomia may be seen alone or in association with other anomalies. It may be unilateral, extending along a line from the commissure to the tragus or bilateral. It is usually partial but rarely complete. Transverse facial clefts are more common in males and more common on the left side when unilateral. The goal of macrostomia reconstruction is to achieve functional, symmetrical, and accurate oral commissure with minimal scar. In this paper, we present a six-year-old girl with unilateral macrostomia with preauricular skin tags and malformation of pinna on ipsilateral side treated with vermillion-square flap method. The scar is placed at the upper lip. At two-month followup, the oral commissures are symmetric, the scars are inconspicuous, and the overall balance of facial contour and lip is excellent. We recommend this method for patients with mild to moderate macrostomia.
