A total of 1890 subjects, aged between 3 and 5 years, and 1377 subjects aged between 12 and 19 years, in different parts of the country were examined. The prevalence of missing teeth in the primary dentition due to 'nylon' teeth practice ranged from 0% to 16.9%, with a weighted mean of 9.5%. Canines were the most involved teeth, accounting for 95% of all missing teeth. Mutilated permanent teeth, a result of traditional extraction of deciduous tooth germs, were observed only in Singida district in 8% of the examined subjects. 22.8% of these mutilations presented as malformations, while the remaining 77.2% presented as missing teeth. Most missing teeth and all the malformed teeth were seen in the mandible. The mandibular canines were the most affected, followed by the mandibular lateral incisors. It is suggested that 'nylon' teeth practice in Tanzania may be a recent invention rather than a traditional tribe related custom. The precariously high prevalence of 'nylon' teeth practice in Tanzania, and the people's perception of this malpractice, requires that particular attention be paid to this issue during oral health educational programmes in the affected communities.</p>","PeriodicalId":76983,"journal":{"name":"African dental journal : official publication of the Federation of African Dental Associations = Journal dentaire africain","volume":"5 ","pages":"21-5"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12981389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The teeth, which resembled the normal deciduous series, were mobile. A striking observation was the anxious behaviour of the mother which prompted further probing. History taking revealed that the mother's anxiety was caused by societal unpleasant reaction to her baby's prematurely erupted teeth. The pressure was so intense that she had to seek medical help. At this tender age of the baby, it is advisable to preserve prematurely erupted teeth in order to prevent malocclusion resulting from premature loss of the deciduous teeth. Therefore, it is highly essential that people in this society be enlightened about such cases in order to reduce the psychological stress on parents of children with a similar condition.</p>","PeriodicalId":76983,"journal":{"name":"African dental journal : official publication of the Federation of African Dental Associations = Journal dentaire africain","volume":"4 1-5","pages":"25-7"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13285282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Open bite also occurred more often in Moshi girls than Bukoba girls. No child had scissors bite in Moshi. Open bite and scissors bite in Bukoba girls and cross-bite in Moshi girls were rare.
