Case Selection Criteria for use with Resin-Infiltrative Treatment of Enamel DecalcificationAlthough one of the primary aims for many orthodontic patients is to achieve improvement in their dental esthetic condition, a high percentage of these patients develop unesthetic, white spot lesions (WSL) during the course of treatment. These lesions develop due to enamel decalcification resulting from bacterial plaque accumulation around difficult to clean brackets and overlying wires and ligation devices. Acids produced locally in this retained plaque will decalcify enamel along the peripheral border of the bonded bracket. Quite often, despite repeated admonishment by the clinician to the patient to take extra care in cleansing these susceptible locations, patients return with large plaque deposits around the brackets, and evidence of the early stages of enamel decalcification: the so-called “white spot lesion” (WSL). The problem becomes obvious at the time of bracket removal, when, although the teeth may now be arranged in near-to-perfect alignment and occlusion, large, white areas of enamel decalcification are prominently displayed, denoting the exact location of where the bonded bracket used to be.
Maxillary growth in patients with complete unilateral cleft lip and palate treated with Nasoalveolar moldingIn patients with cleft lip and/or palate (CLP), the nasolabial defect has a significant esthetic impact on the face and may impair psychosocial development. Nasoalveolar molding (NAM) is a pre-surgical orthopedic technique aimed to improve the alveolar and nasolabial morphology of patients with cleft lip and palate. This technique is used to facilitate and improve the future surgical correction in cleft lip and palate patients. Influences such as differences in patient age and gingivoperiosteoplasty procedures are among many that have made it difficult for conclusive results to be found and published on the impact of the NAM technique on maxillary growth in patients with complete unilateral cleft lip and palate (CUCLP).
