Abstract

Background: Alum has been used as a treatment medication in cases of oral and gingival ulcers, and also asantiseptic mouthwash. This study aimed to examine the effects of different concentrations of Alum on inhibition zone,viability counts and adherence ability of Mutans streptococci compared with deionized water and chlorhexidinegluconate in vitro.Materials and methods: The study dealt with an in vitro study to establish a concentration of Alum mouthrinse thatwould have the minimum inhibitory concentration and minimum bacteriocidal concentration. The second partevaluated the anti-adherence ability of the experimental agents.Results: This study found that the antibacterial effect of Alum increases with its concentration from 50 to 10000 PPMbut still weaker than 0.1% chlorhexidine gluconate. Only concentrations of 5000 and 10000 PPM showed negativeadherence of Mutans streptococci to the tooth surface.Conclusions: This study found that the antibacterial effect of Alum increases with its concentration from 50 to 10000PPM but still weaker than 0.1% chlorhexidine gluconate. Only concentrations of 5000 and 10000 PPM showednegative adherence of Mutans streptococci to the tooth surface

Abstract

Background: Soft tissue impingement and lip form have often been overlooked in previous epidemiological surveys.Materials and Methods: About seven thousand 13 year olds with no history of orthodontic treatment were selected from six governorates (Baghdad the capital, Ninevah, Basrah, Diyala, Anbar and Najaf). An intra-oral clinical examination was used to assess traumatic overbite causing soft tissue impingement and the lip form of each student.Results: Soft tissue impingement was found in 2.7% (2.5% palatally and 0.2% labially). Normal lip form was found in 80.7%, contracting lip form in 14.7% and lip trap in 4.6% of the sample. All the previous were non-significantly related to gender and residency.Conclusion: Iraqi children present a much mre favorable lip form than Western children
