The prevalence of crowding, attrition, midline discrepancies and premature tooth loss in the primary dentition of children in Jeddah, Saudi Arabia.

The aim of the present study is to evaluate the prevalence of crowding, attrition, midline discrepancies and premature loss of primary molars in primary dentition of children resident in Jeddah, Saudi Arabia. Five hundred and two (502) children aged 4-6 years old residing in the city of Jeddah, Saudi Arabia provide the data for the analysis. Crowding was found in 14.7% of the subjects crowding in the maxilla occurred in 27 (5.4%) of the children, and 67 (13.4%) in the mandible. Simultaneous crowding in maxilla and mandible was present in 20 (3.98%) of the subject. The prevalence of crowding was significantly higher in the mandible than the maxilla (P > 0.01) and higher in male (P < 0.05). Midline shift was present in 10% of the children with females showing a significantly higher prevalence than the males (P < 0.001). Attrition was present in 167 (33.3%) of the children. One hundred and sixty children (31.9%) had attrition in enamel, and only 7(1.4%) had attrition, which exposed the dentin. Thirty-one (6.2%) out of 502 children had 51 (0.5%) missing teeth out of total number of 10,040 teeth. Tooth #84 was most commonly lost tooth (P < .025). Overall premature loss of 1st primary molars was found to be significantly higher than 2nd primary molars (P < .001).

A difference in perspective--the North American and European interpretations of tooth wear.

PURPOSE: There is considerable interest in the European dental research literature about the problem of tooth wear and specifically about dental erosion, but this interest does not appear to be matched in North America based on the volume of the literature there. The purpose of this article is to consider the possible explanations for this difference. MATERIALS AND METHODS: This article examines the reasons for this disparity and attempts to explain the difference by reviewing the North American and European literature on the etiology, pathogenesis, and prevalence of tooth wear. RESULTS: It would appear from the literature that the reason for the difference in interest between the 2 continents is a reflection of how the appearance, etiology, and terminology are interpreted and used to define tooth wear, attrition, and erosion. CONCLUSION: Attrition is the wear of teeth against teeth; therefore, by definition any worn surface that does not contact the opposing tooth must have another etiology. An appropriate descriptive term is "tooth wear" when the etiology is multifactorial or cannot be determined. A search of the literature shows more studies in the European literature of the etiology and prevalence of tooth wear than in the North American literature. The thrust of the European studies supports the view that erosion is more important than attrition in the etiology of tooth wear.

Treatment approaches to bruxism.

Bruxism, or the grinding and clenching of teeth, occurs in approximately 15 percent of children and in as many as 96 percent of adults. The etiology of bruxism is unclear, but the condition has been associated with stress, occlusal disorders, allergies and sleep positioning. Because of its nonspecific pathology, bruxism may be difficult to diagnose. In addition to complaints from sleep partners, signs of teeth grinding include masticatory pain or fatigue, headaches, tooth sensitivity and attrition, oral infection and temporomandibular joint disorders. Signs of bruxism include tooth wear and mobility, as well as tender or hypertrophied masticatory muscles and joints. Children with bruxism are usually managed with observation and reassurance. Adults may be managed with stress reduction therapy, alteration of sleep positioning, drug therapy, biofeedback training, physical therapy and dental evaluation. If significant tooth attrition, mobility or fracture occurs, dental referral is mandatory.

Dental erosion: diagnostic-based noninvasive treatment.

Lesions that result from dental erosion can be difficult to recognize--particularly when abrasion and attrition are also present. Consequently, dental erosion is often misdiagnosed and mistreated by radical restorative modalities that compromise the vitality of the pulp. This article provides clinicians with knowledge concerning the diagnosis of the complex lesions of dental wear and demonstrates the conservative treatment of this condition. Two cases that exhibit marked tooth wear in anterior teeth and their subsequent restoration utilizing occlusal principles and composite resin are presented.
