Maxillary canine impaction in orthodontic patients with and without agenesis.

Maxillary canine impaction in orthodontic patients with and without agenesis. Angle Orthod. 2013 Jul 10; Authors: Lempesi E, Karamolegkou M, Pandis N, Mavragani M Abstract Abstract Objective: To assess potential associations between maxillary canine impaction (MCI) and agenesis status as well as between MCI and gender. Materials and Methods: The records of 182 orthodontic patients with agenesis (excluding the third molars) and 630 orthodontic patients without agenesis were examined. Diagnosis of MCI was based on pretreatment panoramic radiographs. Maxillary canines that had not erupted as a result of physical barrier or deflection in the eruption path at the dental age of at least 12 years were considered impacted. Logistic regression analysis was used to test for the associations of interest. Results: MCI was detected in 5.6% (n  =  35) of the nonagenesis group (28 female and 7 male participants) and in 18.1% (n  =  33) of the agenesis group (20 female and 13 male participants). Bilateral impaction was detected in 12 patients (34.3%) of the nonagenesis group and in 11 patients (33.3%) of the agenesis group. There was evidence that maxillary lateral incisor agenesis (odds ratio  =  5.1, 95% confidence interval [CI] 2.5-10.5, P

METHODS: Of 3600 consecutive patients examined, 158 patients presented with CAC as detected by DPR. The final study group was composed of 96 patients who had CAC confirmed by DUSG or CT angiogram. The control gro...

ConclusionThis is the first study to compare PEMF and CMF bone growth stimulators in patients with degenerative pathologies who underwent thoracolumbar spinal fusions. Overall, the addition of these bone growth stimulators does not improve fusion outcomes, although CMF appears superior to PEMF.

Conclusions: Our results confirmed the perpendicularity of the interlaminar line with the pedicle axis in the lumbar spine at all the levels. The interlaminar line is a useful guide for pedicle screw sagittal inclination. PMID: 32050312 [PubMed - as supplied by publisher]

Authors: La Monaca G, Pranno N, Vozza I, Annibali S, Polimeni A, Bossù M, Cristalli MP Abstract Traumatic injuries to the primary dentition are critical events in dentistry not only due to the need for urgent care, but also since they have potential sequelae in the permanent dentition, with a prevalence ranging from 12% to 74%. The aim of this article was to provide an overview of the prevalence, etiology, and clinical and radiographic characteristics as well as the management of permanent teeth sequelae resulting from traumatic injuries to their deciduous predecessors. An extensive literature review was per...

CONCLUSIONS: Pathologies of the 3rd molars and teeth adjacent to 3rd molars can occur as a result of multiple factors. Caries and periodontal disease may also occur due to the inaccessibility to maintain oral hygiene. With a regular follow-up schedule, reinforced by the dentist and good oral hygiene, several pathologies that are significantly associated with non-impacted 3rd molars can be prevented and may not require prophylactic extraction.

Abstract Primary pulmonary coccidioidomycosis (valley fever) is caused by inhaling airborne spores of the fungus Coccidioides immitis or Coccidioides posadasii. Residing in or traveling to areas endemic for Coccidioides is required for the diagnosis; no person-to-person or zoonotic contagion occurs. The incidence of coccidioidomycosis is increasing in endemic areas, and it has been identified as the cause of as many as 17% to 29% of all cases of community-acquired pneumonia in some regions. Obtaining a travel history is recommended when evaluating patients with community-acquired pneumonia. Diagnosis usually relie...
