Completion of root development takes around 3 years after eruption of permanent teeth. Any pulpal injury in this period can lead to necrosis of pulp. Pulp necrosis of immature permanent teeth may impair root development and apical closure of root canals. Management of immature non vital teeth is very challenging for a clinician because teeth may have wide open apex and thin root canal walls that may diverge towards the apex. Conventional cleaning and shaping of the canals and obturation may not be possible because of the lack of apical stop. This case report presents two cases of apexification. First case, managed using Calcium hydroxide and iodoform paste for multiple visit apexification which had a rare apexogenesis like outcome and second case using MTA for single visit apexification followed by root reinforcement with Glass fiber reinforced composite post.

The purpose of this study is to predict the accurate timings for pubertal growth peaks for Class I, Class II - Div 1, Div 2 and Class III. Comparisons are made between the period of the pubertal growth peak in Class I, Class II –Div 1, Div 2 and Class III subjects. This would help the orthodontist in the following ways: 1) For predicting correct treatment time for all malocclusions. 2) For benefiting the patient by guiding the growth modification treatment during the favorable time in a balanced and harmonious manner. 3) To assess skeletal age and pubertal growth spurts are of prime importance in orthodontics and dentofacial orthopedics, for diagnosis, treatment planning, and retention. This study has used the Cervical Vertebral Maturation (CVM) technique for the finding of the peak in growth of mandible, based on the scrutinizing and analysising of the second through fourth cervical vertebrae in a single cephalogram. The lateral cephalograms of orthodontically untreated or new subjects/ patients, ages 8 through 18 years, were studied. The CVM stage on each radiograph was assessed and evaluated according to the Baccetti et al method. Skeletal relationship was evaluated by Steiner’s analysis (By Steiner's analysis: ANB (A point, Nasion, B point) shows whether the relationship amongst the maxilla and mandible is normal (skeletal class I relationship (+ 2 degrees), a skeletal Class II (+4 degrees or more), or skeletal Class III (0 or negative). The Duration of pubertal peak in Class I was 5 months longer than class II patients and 6 months shorter than class III patients. The pubertal peak for Class I subjects lasted 1 year 4 months (in agreement with previous indications of the literature) whereas in subjects with Class II div 1& div 2 malocclusion it lasted for a shorter period (11 months) and Class III malocclusion it persisted for a longer period (1 year 10 months).

The aim of this study is to compare the efficiency of radiopaque dye, decalcification, and histological sectioning in detection of accessory canals in mandibular 1st molars. 30 Extracted mandibular 1st molars were selected. The teeth selected for the study were stored in normal saline. Endodontic access openings were made using a round bur and pulp tissue was removed from the pulp chamber using a standard spoon excavator. Root canal contents were extirpated using barbed broach. Complete debridement of root canals was done using files No. 8 to 25, with copious irrigation using 3% sodium hypochlorite. The teeth were placed in separate bottles containing normal saline and were labeled. Three different methods were used to study the accessory canals, viz, Radiopaque dye, decalcification, and histologic sectioning. According to this study, The incidence of lateral and accessory canals for the mandibular first molar is 46.6%. Results showed that Histological sectioning was significantly ( P = 0.048) better than dye method , but the difference between the Histological sectioning and decalcification was not significant.
