Background:To assess the prevalence of dental diseases among 9–15-year-old visually impaired children and find out its impact on their daily activities using the Child-Oral Impact on Daily Performance (C-OIDP) questionnaire in districts of Uttarakhand, India.Materials and Methods:A total of 423 visually impaired institutionalized children between the age group of 9–15 years were included in the study. Stratified random sampling technique was used to obtain the study population. Dental caries was recorded using dmft for primary dentition and DMFT for permanent dentition, traumatic dental injuries were assessed using traumatic dental injury index, and dentofacial anomalies were recorded using Angle's classification of malocclusion. The Hindi braille version of C-OIDP questionnaire was used to gather information regarding oral health-related quality of life (OHRQoL).Results:There was a high dental caries prevalence of 57.7% in visually impaired children. The prevalence of traumatic dental injuries was 50.6%. Crowding (61.5%) was the most commonly seen dentofacial anomaly and the most commonly perceived oral health problem was toothache. There was less favorable OHRQoL in males as compared to females.Conclusion:There was a high prevalence of dental diseases in this group and higher C-OIDP scores suggestive of unfavorable OHRQoL.

This case report is an insight in to pediatric traumatology whereby bilateral greenstick fracture of condyle is used as a means to discuss the incidence and anatomic considerations for the management of the same, highlighting the fact that dental surgeons require a unique understanding of the anatomy, growth considerations, healing pattern and operative management involving minimal manipulation while managing pediatric facial fractures.

Hindi Child Oral Impact on Daily Performances index can be used as a valid and reliable instrument in measuring OHRQoL. of Paediatric North Indian population.

Background: "Better teeth better health" is a guiding dictum for the 21st century that has been well adopted by WHO and emulated world over by numerous health care agencies. Hence its of paramount importance to assess the impact of oral health on the quality of life. Keeping this in mind the present study was done to gauge the impact of prevalence of dental diseases amongst 9-15 year old institutionalized hearing impaired children in districts of Uttarakhand, India. Materials & methodology: 250 hearing impaired institutionalized 9-15 year old children were examined using WHO type III clinical examination for DMFT/dmft, Traumatic dental injuries using TDI index and dentofacial anomalies using Angle's classification of malocclusion. The Hindi version of the C-OIDP questionnaire was used in this study. Results: There was a high dental caries prevalence of 56% with significant male predilection. TDI index was 40.8% and the most common molar relation was class I with 90.4%. With 49.6% crowding was the most common dentofacial anomaly. Deformity of face or mouth has maximum impact on the daily life of these children. The overall oral health related quality of life was less favorable in this group. Conclusion: Oral health has a significant impact on daily life of these children with hearing impairment and those children having dental diseases showed unfavorable OHRQoL.

The cytotoxicity of a resin-based material can be evaluated on isolated human lymphocyte. Since resin-based dental materials have been used with increasing frequency in anterior and posterior teeth restorations, the uncured resin monomers are leached out from the restorations and diffuses into the dentine and ultimately hampers the odontoblastic layers of pulp as well as gingiva. It is also reaches into the saliva and circulatory blood. The study evaluates and compares the relative cytotoxicity of resin-based dental materials at different time interval, i.e. 24, 48, and 72 hours on human lymphocyte by Trypan blue exclusion method. All resins were found to be cytotoxic to human lymphocyte. Resin samples cytotoxicity was the highest in first 24 hours followed by 48 and 72 hours.
