The present study was conducted with the aim of evaluating and comparing the microleakage of glass ionomer, composite resin and compomers. Class V cavities were made in thirty intact caries free premolars and restored with restorative materials to be tested respectively. The teeth were thermocycled and subjected to silver nitrate dye penetration. They were subsequently sectioned buccolingually. Microleakage was evaluated under a stereomicroscope and data subjected to statistical analysis. The study concluded that microleakage was evident in all restorative materials, with glass ionomer showing maximum leakage followed by composite resin. Compomer demonstrated the best results with minimum leakage.

Taurodontism is an aberration of teeth that lacks the constriction at the level of the CEJ characterized by elongated pulp chambers and apical displacement of bifurcation or trifurcation of the roots, giving it a rectangular shape. Its occurrence in permanent teeth is common and is quite rare in deciduous dentition. Presented in this article are two cases with taurodontism involving deciduous and permanent molars.

Considering the high prevalence of preterm birth (PTB) and low birth weight (LBW) and their complications as well as the role played by periodontal disease in their incidence and the lack of any report of periodontal therapy on these problems in Iran, the goal of the present research was to determine the effects of periodontal treatment on PLBW incidence among women with moderate or advanced periodontitis who were referred to Javaheri hospital (2004-2005). This clinical trial research was conducted on 30 pregnant women age ranging from 18-35 years old, with moderate or advanced periodontitis. Fifteen subjects randomly underwent the first phase of periodontal treatment including scaling, root planning and the use of 0.2% chlorhexidine mouth rinse for one week. None of these steps were taken for the controls. After necessary follow ups, the effect of periodontal treatment on birth term and birth weight were analyzed statistically. This research was conducted on 30 subjects, 15 controls and 15 cases in study group. In the control group, the observed rate of PLBW was 26.7% whereas among periodontally treated group, phase I, PLBW infant was not observed ( P <0.05). Infants birth weight were (3059.3-389.7) gms in study group and (3371-394.2) gms in the control group and respectively ( P <0.05). Periodontal therapy, phase I, results in a reduction in PLBW incidence rate. Therefore, the application of such a simple method among periodontally diseased pregnant women is recommended.

The prevalence of dental caries and treatment needs in the age group of 3-5 years was estimated among 1500 children of Hubli -Dharwad city. The attitude of mothers towards their children's oral health and its relation with caries prevalence was noted among 200 subjects. The prevalence of dental caries was 54.1%. The attitude of mothers towards children's oral health made a statistical difference in the mean dmft levels.

Presented here is a case of a 8 year old boy with typical clinical manifestations of Acrocallosal syndrome. The characteristic features of this syndrome are craniofacial abnormalities, distinctive digital malformation, mental retardation. The clinical and major nosologic aspects of this condition are discussed.

Mandibular distraction osteogenesis has become a popular surgical modality due to its many advantages over conventional orthognathic surgical procedures. However, in spite of the technique having been used for over 15 years, no concrete long term results are available regarding the stability of results. We discuss the various studies which have reported either in favour or against the stablility of results after distraction. We report a series of 6 cases (3 unilateral and 3 bilateral distraction) where distraction was carried out before puberty and followed them up to seven years after removal of distractors. This case series shows that results achieved by distraction osteogenesis are unstable or best unpredictable with respect to producing a permanent size increase in the mandible. The role of the distraction osteogenesis in overcoming the pterygomassetric sling is questionable. We suggest a multicenter study with adequate patient numbers treated with a similar protocol and documented after growth cessation to have meaningful conclusions on the debate of distraction osteogenesis versus orthognathic surgery.

The present study was undertaken to evaluate Midazolam as a Paediatric conscious sedative agent for a routine Indian dental setup and to compare its efficacy and safety when administered by intranasal and intramuscular routes, at a dosage of 0.2 mg/kg body weight. The present study was accomplished in two phases: Phase 1: Preliminary dose finding pilot study on 10 children. Phase 2: Single dose, randomized parallel clinical trial on 40 children between the ages of 2 and 5 years. These children were randomly assigned to two groups consisting of 20 subjects each. Group M, received Midazolam intramuscularly, while Group N received Midazolam intranasally. Both the intranasal and intramuscular groups showed highly significant decrease in crying levels, motor movements and sensory perception levels, post-sedation ( P < 0.001). Though both the routes almost matched each other in their efficacy and safety profiles, the intranasal route showed a significantly faster pharmacodynamic profile in terms of faster onset, peak and recovery times ( P <0.001). Midazolam could be safely and successfully employed by intranasal and intramuscular routes for Paediatric conscious sedation in a routine dental setup with basic facilities at a dosage of 0.2 mg/ kg body weight. Whenever the clinical situation warrants a faster action, peak and recovery, the intranasal route should be the obvious choice.

The present study was carried out to find out the amount of cariogenic and cariostatic trace elements in mixed saliva. It was observed that Cu, Pb, Na showed significant variation in case of one surface as compared to caries free group. Between the non-caries and multiple caries group Cu, Pb, K showed no significant variation Zn showed highly significant variation.

Extraoral sinus tract may occur as a result of an inflammatory process associated with the necrotic pulp. Several non odontogenic disorders may also produce an extraoral sinus tract, the differential diagnosis of these clinical findings is of prime importance in providing appropriate clinical care. Presented here is a case report of 4 year old female child with extraoral sinus tract through which the tooth buds of mandibular permanent left lateral incisor and mandibular permanent left canine were lost. The extraoral sinus was due to mandibular left primary canine with class IX fracture (Ellis and Davey's classification).

Nasally erupting tooth is a rare finding seen associated with cleft lip and alveolus. It may be diagnosed as a result of symptoms such as difficulty in breathing, pain on sneezing or blowing the nose or may remain asymptomatic. A case of a 4 year old male child operated for bilateral cleft lip and alveolus with unilateral right sided nasally erupting deciduous canine is presented here.
