Orthodontic treatment represents an important fraction in dental interventions. According to other medical methods the question for scientific evidence for the effectiveness of these treatments arises. The question of the effectiveness is connected with the question what is understood as an effect. In principle, the effect of the intervention is understood on the basis of the occlusion or denta...

Obstructive sleep apnea (OSA) is a disorder caused by number of factors like an obstruction the upper airway during because insufficient motor tone tongue and/or dilator muscles or inadequate growth maxillary jaw bone etc. Oral appliances (OAs) are commonly used as non-invasive treatment for obstructive syndrome. The primary oral appliance (OA) in mandibular advancement device (MAD). Tongue-ret...

BACKGROUND Many factors can influence oral health including oral hygiene measures, eating habits, attention from parents, education and the social situation. It is even harder to keep good oral health when orthodontic treatments are applied, because orthodontic treatments are usually undergone by children and adolescents who have fewer skills and pay less attention to their oral health; this ma...

It has been documented in vitro and in vivo that metal dental appliances release metal ions due to corrosion. Dentists must choose among many dental casting alloys available, often without knowledge of their biological properties and effect on oral mucosa. The aim of this study was to measure metal content of nickel (Ni) and chromium (Cr) in whole saliva of 85 patients with and without metal de...

OBJECTIVE To evaluate the effects of space maintainers on plaque accumulation, periodontal health and oral microflora. SUBJECTS AND METHODS The study participants comprised 38 patients aged 4-10 years requiring either fixed or removable space maintainers. Plaque index, gingival index, bleeding on probing index, candidal colonization and Enterococcus faecalis were recorded just before the appl...

Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder with periodic reduction or cessation of airflow during sleep. It is associated with loud snoring, disrupted sleep, and witnessed apneas. Treatment of OSA varies from simple measures such as oral appliances and nasal continuous positive airway pressure (CPAP) to surgical procedures like uvulopalatopharyngoplasty an...

Objective: To evaluate the effects of fixed orthodontic treatment on gingival health. Materials and methods: In the present study 30 orthodontic patients under fixed mechanotherapy mean aged 19.82 years were selected. The selection criteria were: Treatment that consisted of full-mouth fixed orthodontic appliances. Exclusion criteria included patients with systemic disease, are on antibiotics or...

Intra-oral appliances such as transpalatal arch and Nance appliance fail to resist against forces that tend to loosen the anchorage. The infirmity arises due to the long lever arm and the mesial force that is perpendicular to the long axis of the appliance. The butterfly arch is presented here as an intra-oral appliance that withstands the mesially directed forces with a mechanism that puts str...
