Endodontic management of immature non vital permanent teeth in young pediatric patients is a great challenge to dentists. The walls of the root canals are frequently divergent and open apexes make debridement and obturation difficult. Thus closure of root apex is very essential for success of the endodontic treatment. Although different materials are used for the apexification procedure, calcium hydroxide is the material of choice for apical barrier formation and healing. There are different opinions regarding frequency of CaOH dressing change to induce complete closure of the apex. Literature suggests that dressing should be changed frequently. Therefore the aim of the present article is to report the successful closure of root apex in pulpless permanent incisors with wide open apices in a pediatric patients using CaOH dressing.

Oral lichen planus (OLP) is a T-cell-mediated chronic inflammatory oral mucosal disease of unknown etiology. OLP presents as white striations, white papules, white plaques, erythema, erosions, or blisters affecting predominantly the buccal mucosa, tongue and gingiva. Both antigen-specific and non-specific mechanisms are hypothesized to be involved in the pathogenesis of oral lichen planus (OLP). Antigen-specific mechanisms in OLP include antigen presentation by basal keratinocytes and antigen-specific keratinocyte killing by CD8+ cytotoxic T cells. Non-specific mechanisms include mast cell degranulation and matrix metalloproteinase activation in OLP lesions. These mechanisms may combine to cause T cell accumulation in the superficial lamina propria, basement membrane disruption, intra-epithelial T cell migration and keratinocyte apoptosis in OLP. The various hypotheses proposed for pathogenesis of oral lichen planus are discussed in this review. © 2010 John Wiley & Sons A/S.

Aim of this study was to determine the validity of cervical vertebrae radiographic assessment to predict skeletal maturation.Left-hand wrist and lateral cephalometric radiographs of 100 Bangalore children aged 8-18 years, divided into 10 groups of 10 subjects each with equal distribution of males and females, were measured. On left-hand wrist radiograph, the classification of Fishman was used to assess skeletal maturation. Cervical vertebrae maturation was evaluated with lateral cephalometric radiograph, using the stages developed by Hassel and Farman. The changes in hand wrist and cervical vertebrae were correlated.Significant association was observed between skeletal maturation indicator stages and cervical vertebrae maturation indicator stages. Correlation coefficient was found to be significant (P<0.0001).The results of the study indicated that the cervical vertebrae maturation and hand wrist skeletal maturation was significantly related.

Skeletal age had been assessed by comparison between maturation of hand-wrist with stages of cervical vertebrae or canine calcification stages in past and this had been closely related to craniofacial growth. The importance of pubertal growth spurt in various types of orthodontic therapies is already established.Hence, this study was aimed to evaluate the relationship of skeletal maturity by hand-wrist with cervical vertebral maturation indicators and canine calcification stages.The study consisted of randomly selected 90 children from Lucknow population with 45 males (age range 10-13 years) and 45 females (age range 9-12 years). Lateral Cephalogram, hand-wrist x-ray, and periapical x-rays of maxillary and mandibular right canines were taken.Mean, standard deviation was calculated of different groups. Correlation was made among cervical vertebral maturation, hand wrist maturation, and canine calcification stages at various age groups.There was strong correlation between skeletal maturation indicator and cervical vertebral maturation indicator for both male (0.849) and female (0.932), whereas correlation between skeletal maturation indicator and canine calcification was good for both male and female (0.635, 0.891).It was concluded that cervical vertebral maturation indicator and canine calcification stages can also be used for assessing skeletal maturity.

This study was designed to evaluate the buccal corridor in smile esthetics and to correlate it with underlying hard tissues.Posed smiling frontal photographs, digital posterior-anterior (PA) cephalograms, and study models of 25 males and 25 females in age range of 18-25 years were taken. Photographs were evaluated for smile esthetics by eight orthodontists, eight plastic surgeons, eight beauticians and eight lay people to group them into three groups with least attractive, average and attractive smile and buccal corridor width was measured. Digital PA cephalograms were transferred on Nemo-tech software for frontal facial analysis. Intercanine and intermolar widths were measured on upper study model with the help of a digital calliper.The buccal corridor width was least in attractive smile group and maximum in least attractive smile group. The buccal corridor width had a negligible correlation with hard tissues and a mild to moderate inverse correlation with intercanine and intermolar widths within the groups.As the amount of buccal corridor display was increased, smiling images were scored less attractive by the evaluators. The buccal corridor is not influenced by underlying skeletal hard tissues but have mild to moderate inverse correlation with the intercanine and intermolar width.
