A 16-year-old female patient with skeletal Class III malocclusion and bilateral posterior cross bite complaining of difficulty in chewing was treated orthodontically without surgery (camouflage treatment). The treatment comprised of fixed orthodontic treatment with MBT prescription (0.022˝×0.028˝ slot) using quad helix appliance for bilateral expansion of maxillary arch and Class III elastics for occlusal correction. Post-treatment records showed normal overbite and overjet with acceptable occlusion. So with this treatment strategy of expanding the maxillary arch using a quad helix appliance and use of Class III elastics, we achieved a good result with optimal occlusion...

Domestic rabbits are increasing in popularity as household pets; therefore, veterinarians need to be familiar with the most common diseases afflicting rabbits including dental disease. Current diagnostic approaches include gross oral examination, endoscopic oral examination, skull radiography, and computed tomography (CT). Cone beam computed tomography (CBCT), a new oral and maxillofacial imaging modality that has the capability to produce high-resolution images, has not yet been described for use in evaluating dental disease in rabbits...

The local anesthetic systemic toxicity can be due to increased blood lignocaine levels or due to increased sensitivity to lignocaine. Several cases of lignocaine-induced central nervous system toxicity have been noted, but none have reported only loss of consciousness without any seizure-like activity. Intravenous lipid emulsion administration for the treatment of local anesthetic systemic toxicity is an emerging topic of discussion, and there are case reports where they had successfully been used. However, majority of them were used in the treatment of cardiovascular manifestations of local anesthetic toxicity...

Blepharocheilodontic (BCD) syndrome is a rare condition characterized by bilateral cleft lip and palate (BCLP), eyelid abnormalities, and oligodontia. Despite orofacial clefting and oligodontia being central features of the condition, detailed reports of dental and craniofacial characteristics are scarce. The aim of this study was to analyze the dental and craniofacial features in a group of patients with BCD syndrome (three of which were related). Cephalometric radiographic analyses were performed on BCD syndrome patients (all radiographs taken at age 8 years) and compared to 40 randomly selected age-matched controls (20 non-syndromic BCLP, 20 non-cleft)...

REVIEW
Giuseppe Perinetti, Luca Contardo
Current evidence on the reliability of growth indicators in the identification of the pubertal growth spurt and efficiency of functional treatment for skeletal Class II malocclusion, the timing of which relies on such indicators, is highly controversial. Regarding growth indicators, the hand and wrist (including the sole middle phalanx of the third finger) maturation method and the standing height recording appear to be most reliable. Other methods are subjected to controversies or were showed to be unreliable...
