A basic study was made to examine what extent of radiographic changes pertaining to early periodontal disease. The standardized radiography was used to assure geometrically identical radiographs. Artificial bone defects were produced by stages at the proximal bone crest using humane dry mandible. And as to when changes occurring in the bone on dental film can be recognized, visual assessment wa...

A dental curing light is a piece of dental tool that is used for the hardening of light cure composites. Many studies have shown these lights induce changes in DNA, mitosis and mitochondria through free radicals production. Light emitting diode (LED) are most commonly used and claim less hazards to the adjacent soft tissues. Current study was therefore designed to observe the morphological chan...

OBJECTIVE To evaluate skeletal and dental changes in growing individuals through lateral cephalograms obtained after the sole use of the splint-type Herbst appliances in Class II division 1 malocclusions. METHODS Several electronic databases (Pubmed, Medline, Medline In-Process & Other Non-Indexed Citations, Cochrane Library Database, Embase, Web of Sciences, Scopus, and Lilacs) were searched...

A conservative, noninvasive or minimally invasive approach to clinical management of dental caries requires diagnostic techniques capable of detecting and quantifying lesions at an early stage, when progression can be arrested or reversed. Objective evidence of initiation of the disease can be detected in the form of distinct changes in the optical properties of the affected tooth structure. Ca...

BACKGROUND: Oral health of the populations is increasingly becoming important both in developed as well as developing countries. With rapid changes in the lifestyle related behaviors including diet it is important to study the occurrence of common dental problems presented to the dental OPD. MATERIALS AND METHODS: This descriptive cross sectional hospital based survey was carried out to know in...

Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutri...

OBJECTIVE The present study assessed the maxillary dental arch changes produced by surgically assisted rapid maxillary expansion (SARME). METHODS Dental casts from 18 patients (mean age of 23.3 years) were obtained at treatment onset (T1), three months after SARME (T2) and 6 months after expansion (T3). The casts were scanned in a 3D scanner (D-250, 3Shape, Copenhagen, Denmark). Maxillary den...

The embryonic head development, including the formation of dental structures, is a complex and delicate process guided by specific genetic programs. Genetic changes and environmental factors can disturb the execution of these programs and result in abnormalities in orofacial and dental structures. Orofacial clefts and hypodontia/ oligodontia are examples of such abnormalities frequently seen in...

BACKGROUND Whether skeletal effects are obtained by functional appliances in class II subjects is still controversial. In this regard, most of the available studies did not clearly identify the growth phases (i.e. pubertal or not) of the treated patients. This retrospective controlled study aimed at evaluating the skeletal and dental changes in class II subjects produced by the functional regul...
