Objective: To evaluate the influence of fluoride varnish (FV) therapies or resin infiltration (RI) to maintain the structural integrity of Molar Incisor Hypomineralization (MIH) -affected teeth.
Methods: Fifty-one children aged 6-12 years with at least one incisor and one first permanent molar with yellow/brown MIH opacities were included. Patients were randomly allocated into three groups: FV - Fluoride Varnish (Duraphat); FV+etch - Fluoride Varnish (Duraphat) after enamel etching with 37% phosphoric acid; or RI - Resin Infiltration system (Icon).
Background: The difficulties of caries diagnosis and the level of examiner's experience may influence the treatment decision, resulting excessive and inefficient intervention.
Aim: This randomized experimental study evaluated caries treatment decisions made by undergraduate (UG) and postgraduate (PG) students when examination was performed through conventional visual clinical examination (CVCE) and when supported by ICDAS (IC) or Nyvad's (NY) criteria.
Design: Four UG and four PG initially analyzed, by CVCE, 300 primary incisors and molars surfaces of 25 children aged 5-12 years, and choose between no treatment, non-operative, and operative treatment.
Objective: To evaluate, prospectively, the influence of examiner's experience in interpreting and applying the caries detection systems ICDAS (IC) and Nyvad (NY).
Material And Methods: Twelve second-year undergraduate dental students (UG) and 12 postgraduates (PG) MSc level analysed and codified 77 clinical dental caries photographs at three different moments: initially, without any training; after one week of receiving training through a theoretical class; and after two years. Reproducibility and correlation was evaluated; sensitivity, specificity and area under ROC curve (AUC) were dichotomized according to the presence of cavitation (IC) and in relation to disease activity (NY).
Background: Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a distinct subtype of inflammatory gingival hyperplasia that shows lack of response to traditional periodontal treatment, and after surgical excision, recurrence rate of 6-16% has been reported.
Case Report: Two girls (11- and 9-year-old) with multifocal red patches along the maxillary and mandibular labial gingiva showed no regression of the lesions after basic periodontal treatment. Surgical excision of focal lesion in each case was performed, which showed typical features of LJSGH.
