objectives: attached gingival width (agw) is an important marker for diagnosis of periodontal disease and normal gingival sulcus depth (gsd) is a sign of healthy periodontium. the aim of this study was to determine the agw and gsd in3-15 year-olds with three dentition systems in isfahan in 2001.   methods: a total of 360 students (120 students in each system) eligible for this cross sectional s...

objectives: proper diagnosis and prevention of malocclusion are superior to treatment. discrepancy between arch length and tooth size in mixed dentition period is a condition requiring timely diagnosis. estimating the mesiodistal width of unerupted teeth according to the size of erupted ones can lead to earlier diagnosis of malocclusion. on the other hand, the best timing for serial extractions...

This retrospective study aimed to evaluate the difference in measurement between conventional orthodontic analysis and artificial intelligence pediatric adolescent patients aged 7 - 15 with mixed permanent dentition. A total of 60 (30 dentition, 30 dentition) who underwent lateral cephalometric radiograph for diagnosis were randomly selected. Seventeen landmarks identified, 22 measurements calc...

An ideal primary dentition is the indicator of future ideal permanent dentition. Absence of primate or secondary spaces in the primary dentition is expression of disproportion between jaw/tooth sizes. Little information is known on the relationship of spacing and closed dentition with malocclusion in relation to primary and permanent dentition. Hence, the present study was conducted to find the...

Background: The eruption of the first permanent molar (FPM) marks beginning mixed dentition, which is one most dynamic periods in development and growth stomatognathic system. Aim: purpose study was to investigate pathology during transition stage between primary dentition. Materials Methods: A literature search performed Clarivate Web Science, Google Scholar, PubMed databases. Cohort cross-sec...

We performed measurement using a 3-dimensional measurement system in study models of children with anterior crossbite in the primary dentition treated using a chin cap and lingual arch, and evaluated changes in the dentition and occlusion after treatment based on measurement values and also using wire frame models. Comparing with the situation before treatment, the overbite of anterior teeth sh...

incontinentia pigmenti (ip) is an x-linked dominant genodermatosis characterized by typical skin lesions along blaschko's lines and associated with ocular, dental, nails, hair, skeletal, central nervous system and cardiovascular anomalies. we report a 5-year-old boy with cutaneous hyperpigmentation along blaschko's lines, atrophic streaks, strabismus and mental retardation. he showed the charac...

The purpose of this study was to comparatively study and elucidate the characteristics of masticatory function of the subjects with complete denture and those with normal natural dentition. The study were carried out on 20 subjects with normal natural dentition and 30 subjects with complete denture having clinically good prognosis. Masticatory movements were analyzed by electromyograph (EMG) an...
