Identification and description of controlled clinical trials in Spanish language dental journals.

BACKGROUND: To identify controlled clinical trials (CCTs) published in Spanish and in Latin American dental journals, and provide access to this body of evidence in a single source. METHODS: Handsearching, following Cochrane Collaboration guidelines, of CCTs published in Spanish dental journals from Spain and Latin America. For each eligible trial, we collected the dental specialty, the interventions evaluated, whether and how randomisation was achieved, and the corresponding bibliographic reference. RESULTS: We handsearched 107 journals published in Spain and Latin America in Spanish. Over 17 051 articles, 244 (1.43%) were CCTs. These studies focused mainly on periodontics (70, 29.0%) and oral and maxillofacial surgery (66, 27.0%), assessing mostly pharmacological interventions (112, 46.0%). One hundred fifty-three studies (62.7%) used a random allocation of participants to study arms. CONCLUSIONS: A significant number of dental journals published in Spain and Latin America in Spanish language present original research relevant to inform clinical practice. These journals are not indexed in the major electronic databases. PRACTICAL IMPLICATIONS: References to the identified CCTs are now available in CENTRAL, the Cochrane Collaboration repository for these studies. We call for adherence to the CONSORT statement in dentistry to improve reporting of CCTs in journals published in Spanish language.

Protocol for the treatment of anterior open bite patients: an evaluation.

AIM: To evaluate dental, skeletal, and facial changes related to the extraction of second premolars in patients treated with a particular protocol for dental anterior open bite. METHODS: The cephalometric films of 26 patients were analyzed at the beginning of treatment and after the completion of treatment. The sample was divided into 2 groups: growing and nongrowing. RESULTS: The data showed retrusion and extrusion of incisors, mesial and extrusive movement of the molars, and slight changes of the ANB angle with minimal changes in the mandibular plane angle. Lips retruded and improved the profile. Only the vertical movement of the molars showed statistically significant differences. CONCLUSION: This protocol allows predictable treatment of anterior open bite malocclusions with mesial movement of the molars, distal movement of the incisors, and some extrusion of both. This therapy has minimal skeletal effects and favorably influences the soft tissue profile.

Ectopic eruption and severe root resorption.

The treatment of a patient with maxillary canine-central incisor transposition is presented. Treatment options were limited because the roots of the maxillary right lateral and central incisors had severe resorption and generalized shortening. The multidisciplinary approach and treatment sequence used to achieve an esthetic and functional result are discussed in this case report.
