Ectodermal dysplasia (ED) is a rare hereditary disease characterized by a congenital dysplasia of several structures of ectodermal origin. Common manifestations include defective hair follicles and eyebrows and deficiency of sweat glands. Intraorally, anodontia, hypodontia or oligodontia are the most common findings. We report the case of a four-year-old girl who was referred to the pediatric dentistry department of hospital la Rabta (Tunisia) and exhibited many of the dental manifestations of ED as well as general abnormalities. Our early oral rehabilitation was launched to improve oral functions and esthetics by including the fabrication of two removable prostheses and acid-etched composite resin restorations. The patient reported a good adaptation of the conventional dental removable prosthesis and parents were satisfied with the treatment.

The aim of this study was to evaluate the dental students’ perceptions toward the use of social media (Twitter) in an orthodontic course and the impact of this technology for teaching and learning. An online questionnaire was developed to evaluate 4th year students’ knowledge, use, and perceptions of Twitter for teaching and learning in an orthodontic course at Riyadh Colleges of Dentistry and Pharmacy. 85 of the students completed the questionnaire. Of the respondents, 75% reported having used Twitter on a daily bases. 58% of them they didn’t think that they will like the use of twitter for teaching. After their experienced it, 82% they liked it. The students perceived the Twitter sessions as enjoyable and reported it improved their engagement in orthodontic class. The results of this study indicated that students agreed that the use of Twitter had enhanced the learning environment in the orthodontic course.

The aim of the study was to determine the antibacterial activity of pure Bacopa monnieri extract on periodontopathogenic bacteria; Porphyromonas gingivalis(Pg), Prevotella intermedia (Pi), Fusobacteria nucleatum (Fn) & Aggregatibacter actinomycetemcomitans (Aa). The minimum inhibitory concentration (MIC), minimum bactericidal concentrations (MBC) and Time kill curve assay were performed to assess the antibacterial effect of both ethanolic and aqueous extract of pure bacopa monnieri against periodontopathogenic bacteria by serial dilution method and colony forming units respectively. MIC values of ethanolic extract were in a range of 25-100 µg/ml for Pi, Fn and Pg and Aa showed a value of 0.8 µg/ml whereas the MIC values of aqueous extracts were in a range of 50-100 µg/ml and that of Aa was 0.4 µg/ml. The time kill curve showed a fast and sharp antibacterial activity of the ethanolic extract over Pi, Fn and Aa at baseline (0 min) whereas Pg showed no growth of colonies at 2 hours.The ethanolic and aqueous extract of Bacopa monnieri exhibited durable antibacterial activity on common periodontogenic bacteria.

Potentially malignant disorders and oral cancer are common diseases effecting oral cavity. The survival rate of these patients has not much improved, inspite of advances in the treatment modalities, due to their adverse effects. Many alternative medicines such as turmeric, aloevera, neem, tulsi, green tea, photo dynamic therapy, CO2 laser and stem cell culture etc are used to overcome these adverse effects. The aim of this study is to investigate the efficacy of turmeric along with honey in reducing the burning sensation in oral submucous fibrosis. Clinically diagnosed 30 patients of Oral Submucous Fibrosis (OSMF) were selected and local application of turmeric and honey was advised. Burning sensation using VAS scale was evaluated after 30 days. Statistical analysis was done using‘t’ test. There was significant decrease in VAS scale after treatment. In our study turmeric and honey showed positive results in reducing burning sensation in OSMF.

To assess the distribution and severity of tooth wear among adult population of Andhra Pradesh. A descriptive cross sectional study was conducted by trained and calibrated examiner. A stratified random sample of 1611 individuals with the age of 35-44 years were examined for tooth wear using Smith and Knight tooth wear index (1984). Descriptive statistics were applied to the data. Prevalence of tooth wear amounted to 70.62%. The highest frequency of score 1 was found for mandibular right 1st molar (41.6%) and score 2 for maxillary left central incisor (20.8%), score 3 for mandibular left 1st molar (6.3%) and score 4 for mandibular left 2nd premolar (7.3%). Occlusal surfaces were most commonly affected with tooth wear when compared to buccal, lingual and cervical surfaces. It also shows that occlusal surfaces of maxillary and mandibular anterior teeth were more commonly affected than the posterior teeth. No tooth wears on the lingual surfaces of posterior teeth of both the arches. Tooth wear remains a common finding in study population. Furthermore, the question of whether tooth wear is a public health problem remains open for debate.

The aim of this study was to compare three types of commercially available brackets for corrosion susceptibility after immersing them in artificial saliva. A total of 360 brackets were used. The brackets were divided in to four groups (Control Group X and Experimental Groups A, B and C). The experimental groups were divided on the basis of duration of immersion in artificial saliva of pH 6.75 ± 0.15. Each group was divided in to corresponding subgroups. The bracket surfaces were analysed using UV –Visible Spectrophotometer and Small Angle Xray Scattering (SAXSS). ANOVA (Analysis of One Way Variance) was used for group comparisons. For post hoc comparisons Newman-Keuls multiple posthoc procedure was applied. Leone and Nu Edge Cr- Co brackets showed progressive signs of corrosion and leaching of Fe and Mg ions after immersion in artificial saliva. Discovery SL brackets showed no signs of corrosion. Leone and Cr-Co Nu Edge are susceptible to corrosion activity in comparison to Discovery SL brackets.
