The premature loss of the primary teeth is due to different factors like the level of caries activity, the oral hygiene, the presence of fluoride in the water, the socioeconomic status of the population, the philosophy of the dentist (3). The aim of this article is to compare the D 4 MF(T+t) index of children with premature loss and those without premature loss of deciduous teeth. The subject of monitoring of the clinical research were 140 children between the age of 6 and 9. The clinical group consisted of 90 children with prematurely extracted teeth, divided into three groups. The control group consisted of 50 children with intact denture. The dental status was examined and registered according to the WHO by the D 4 MF (T+t) index. There was a statistically significant difference in the D 4 MF(T+t) index between the control groups (1.40±0.13) and the clinical groups (4.68±0.33, 4.90±0.41 and 5.76±0.41). The children with premature extraction of the temporary teeth had a higher caries activity with significantly more complicated carious lesions compared to the control group (children without early loss of teeth). The children from the third group, with prematurely extracted temporary teeth and severe orthodontic deformation have the highest prevalence of D 4 MF(T+t). These results demonstrate the connection between D 4 MF(T+t), the malocclusions and the need of prophylaxis.
Mandibular diastema does not occur often, however, its abnormal characteristics have more disturbing implications. A major etiologic factor for mandibular diastema are pernicious habits associated with tongue thrust in a low rest position. The aim of this study is to report the approach and effects of intercepting the deleterious habit of tongue interposition and tongue thrust swallowing and the resultant periodontal changes. Tongue interposition and tongue thrust swallowing in lower jaw may lead to gingival recession, loss of alveolar bone, tooth mobility and diastema. Early termination of bad habits allows for prevention of periodontal problems and possibility of regeneration of soft and hard tissues. In the case study reported intercepting the tongue thrust on lower incisors led to the restoration of alveolar bone, reversing the recession and a spontaneous self-correction of the 7-mm diastema. Thus loss of teeth due to the periodontal problem was prevented and periodontal surgery to restore the level of the bone and gingiva was avoided..
Premature extraction of temporary teeth is a consequence of different factors such as socioeconomic status of the population, level of caries activity, oral hygiene, presence of fluoride in water, philosophy of the dentist. The aim of this article is to compare the DMF (T+t) between children with premature extraction and those without premature extraction. Subject of monitoring of the clinical research were 140 children between 6 and 9 years old. The clinical group consisted of 90 children with prematurely extracted teeth, divided into three groups. The control group consisted of 50 children with intact denture. The dental status was examined and registered according to the WHO by the DMF (T+t). There was a statistically significant difference in the distribution of caries DMF(T+t) between the control groups (2.34±019) and clinical groups (between 5.17±0.33 and 6.40±0.41). The children with premature extraction of temporary teeth had higher caries activity compared to the control group (children without early loss of teeth). The children with prematurely extracted temporary teeth and severe orthodontic deformation had the highest prevalence of DMF(T+t). These results demonstrate the connection between DMF(T+t), malocclusions and the need for prophylaxis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
