ContextEruption of teeth is influenced by various factors. Very few studies were carried out in the past on the eruption time of teeth in the Indian population.AimThe aim of the study is to determine the time and sequence, gender differences, pattern of symmetry in the eruption of permanent teeth in Hyderabad children.Materials and methodsIn this cross-sectional study, 1654 schoolchildren (806 girls and 848 boys) in the age group of 5 to 15 years from Hyderabad were examined for the status of eruption of permanent teeth.Statistical analysis usedResults were subjected to probit’s regression analysis. The average age at eruption of permanent teeth, excluding third molars, was given as the mean [± standard deviation (SD)] in months for each gender. A table of percentiles of the eruption time was also determined.ResultsUnlike most of the earlier studies which showed that girls are ahead of boys in permanent teeth emergence, no such pattern was observed. No significant difference was found in the eruption of permanent teeth in right and left arches. Eruption of all the mandibular teeth, with the exception of right first premolar (44) in both the genders, was earlier than their maxillary counterparts. There was overall delay in the eruption of permanent teeth and significant delay in the eruption of lower canines in both genders.ConclusionThe significant delay in the eruption of permanent mandibular canines is relevant for orthodontic treatment planning.How to cite this article: Chaitanya P, Reddy JS, Suhasini K, Chandrika IH, Praveen D.

Background: Chlorhexidine gluconate is a widely used antimicrobial agent. Adding chlorhexidine and quaternary ammonium compounds to filling materials, such as composite resins, acrylic resins, and glass ionomer cements increases the antibacterial property of restorative materials. This study includes antibacterial property of glass ionomer restorative cements with chlorhexidine gluconate.Aim: The primary objective of our study was to compare the antimicrobial properties of two commercially available glass ionomer cements with and without chlorhexidine gluconate on strains of mutans streptococci.Materials and methods: Two glass ionomers (Fuji II Conventional and Fuji IX) were used. Chlorhexidine gluconate was mixed with glass ionomer cements, and antimicrobial properties against mutans streptococci were assessed by agar diffusion. The tested bacterial strain was inhibited and the antimicrobial properties decreased with time.Results: The highest amount of antimicrobial activity with mean inhibitory zone was found in Fuji II with chlorhexidine gluconate followed by Fuji IX with chlorhexidine gluconate, Fuji II without chlorhexidine gluconate, and Fuji IX without chlorhexidine gluconate.Conclusion: The results of the study confirmed that the addition of 5% chlorhexidine gluconate to Fuji II and Fuji IX glass ionomer cements resulted in a restorative material that had increased antimicrobial properties over the conventional glass ionomer cements alone for Streptococcus mutans.How to cite this article: Yadiki JV, Jampanapalli SR , Konda S, Inguva HC, Chimata VK.

Introduction: Juvenile Idiopathic Arthritis (JIA) is a chronic rheumatic disease, with a prevalence of 1 in 1000 children under the age of 16 years. The clinical symptoms include inflammation of joints, swelling of synovial membrane resulting in growth disturbances and loss of bone density. Aim: To assess the effect of JIA on the development of Temporomandibular Joint (TMJ) and occlusion in children and young adolescents in the age group of 8-16 years and to evaluate the effect of TMJ arthritis on the growth of maxilla and mandible. Materials and Methods: This is a descriptive cross-sectional study with a study and control group. A total of 44 children with JIA attending the Department of Rheumatology, Nizam Institute of Medical Sciences (NIMS), within the age group of 8-16 years were screened and enrolled in study from May-July 2014. A gender and sex-matched healthy control group were enrolled from Paediatric Dentistry outpatient specialty. For the measurement and comparison of arch perimeters of mandible and maxilla, the JIA and control group were divided into sub-groups 1 (8-10 y), 2 (11-13 y), and 3 (14-16 y). All the parameters were recorded and subjected to statistical analysis. An Independent sample t-test was used to find a significant difference for maxillary and mandibular arch perimeters among both the groups. Chi-square test was used to know the difference for TMJ parameters, occlusion and occlusal abnormalities. The level of significance was set at p<0.05 for all tests. Results: Children in the JIA group had reported TMJ pain on movement (40.9%), clicking sounds (36.4%), and dislocation (22.7%). Angle’s class II malocclusion was seen in 36.4% compared to the control group (4.5%). The mean arch perimeter of the mandible was significantly less among JIA children in subgroups 2 (73.00±3.03 mm), and 3 (71.77±6.27 mm) when compared to healthy controls. Other occlusal abnormalities such as increased overjet (34.1%), decreased overbite (31.8%), and crowding (54.5%) were reported in significant percentages compared to healthy controls. Conclusion: The mean arch perimeter of the mandible in the JIA group is less when compared to children of the same age in the control group. There is increased predilection of developing Angle’s class II Malocclusion in the JIA group. From a paediatric dentist perspective, it’s important to understand the overall impact of JIA on stomatognathic system, and an early intervention is recommended.
