A retrospective study on the relationship between miswak chewing stick and periodontal health.

Chewing sticks have been used for centuries as a tooth cleaning device. One of the most commonly used types is known as the miswak. Despite its wide use, few studies have examined its effects on the gingival health. The purpose of this study is to examine the relationship between miswak and gingival health in terms of pocket depths, periodontal disease severity and gingival recession. The incisors, canines and premolars were examined in a total of 264 patients who were seen for routine periodontal treatment. Information regarding the use of the miswak, oral hygiene habits, as well as clinical measurements of pocket depth, periodontal disease and gingival recession were obtained from patients charts. Patients were divided into two groups: a miswak group and a Toothbrush group. The results of this study indicated that the use of miswak may influence periodontal health and may be considered as a factor contributing to gingival recession. It is suggested that additional research is needed to examine the relationship between miswak and periodontal health.

Bleaching of discolored teeth.

Bleaching is a viable treatment alternative to attempt esthetic improvement of discolored teeth. Natural tooth structure as opposed to a veneer or crown margin is considerably superior in tissue response. Caution has to be exercised in selecting cases and advising patients of the possibilities from bleaching and that bleaching may not be entirely successful or lasting. It still should be considered as a treatment of first choice. If applied properly and in carefully selected cases the results can be very rewarding for the dentist and especially the patient. A knowledge of the agents used and biological limits must be kept in mind when bleaching teeth to prevent potential disastrous complications. It is especially important to keep the bleaching time to the shortest effective time possible with vital pulps. Bleaching when successful provides a superior margin and a less expensive alternative than crowns. Bleaching should generally be considered before crown preparation because if bleaching is unsuccessful crowns can always be fabricated. This is true for younger individuals with tetracycline stained teeth because crowns may need to be remade several years after their initial placement due to further eruption of teeth and further recession of the gingival tissues.

The relationship between chewing sticks (Miswak) and periodontal health. 3. Relationship to gingival recession.

Aggressive or improper toothbrushing techniques may have a detrimental impact on the gingiva. The purpose of this study was to examine the relationship between chewing sticks (Miswak) and gingival recession. Gingival recession was measured on the mid facial surfaces of the incisors, canines, and premolars in 238 patients presenting for routine dental appointments. All patients had been interviewed previously regarding their oral hygiene habits and use of Miswak. Patients were divided into three groups: Miswak group, toothbrush group, and Miswak/toothbrush group. The Miswak users had significantly more (P less than or equal to .05) sites gingival recession than did the toothbrush users. Furthermore, the severity of the recession was significantly more (P less than or equal to .05) pronounced in the Miswak users than it was in the toothbrush users.

The relationship between chewing sticks (Miswak) and periodontal health. 2. Relationship to plaque, gingivitis, pocket depth, and attachment loss.

For centuries, chewing sticks have been used as a tooth-cleaning device. One of the most commonly used types is known as the Miswak. Despite its common use, few studies have examined possible effects on the gingiva and the surrounding structures. The purpose of this study was to examine the relationship between Miswak and periodontal health. The incisors, canines, and premolars were examined in 236 patients. All patients were interviewed regarding their demographic data, oral hygiene habits, and use of Miswak. Clinical examination included scoring of plaque, gingival inflammation, pocket depths, attachment loss, and gingival recession. Patients were divided into three groups: a Miswak group, a toothbrush group, and a Miswak/toothbrush group. The results of this study indicated that use of the Miswak may influence plaque accumulation and periodontal health.

Relationship between chewing sticks (Miswak) and periodontal health. Part 1. Review of the literature and profile of the subjects.

For more than 1,000 years, Moslems all over the world have used chewing sticks (Miswak) as an oral hygiene aid. In spite of the introduction of modern oral hygiene devices, many Moslems still prefer to use the natural Miswak. Despite its common use, there is a paucity of data bout its effects on the periodontal structures. This is the first of a three-part series examining the relationship between Miswak and periodontal health. Part I presents a review of the current literature and a demographic profile of the study population. Patients presenting for routine dental appointments were subjected to a comprehensive interview regarding their demographic data, oral hygiene habits, and use of Miswak. Clinical examination included scoring of plaque and periodontal health.

Synthesis of morpholinobiguanide derivatives.

Several new morpholinobiguanide derivatives were synthesized to be tested as hypoglycemic agents, by condensing morpholinobiguanide with alkyl or aryl isocyanate and isothiocyanate, and with dialkylaminoalkyl chloride. The carbamate, prepared from morpholinobiguanide and ethyl chloroformate, was condensed with different aryl amines and certain sulpha drugs. Most of the prepared compounds are easily soluble in water and preliminary examinations as hypoglycemics show promising results.
