Association between fixed orthodontic treatment and dental caries: a 1-year longitudinal study.

This longitudinal study aimed to assess the association between the use of fixed orthodontic appliances and the incidence/increment of active caries lesions in adolescents and young adults over a one-year period. A total of 135 10-30-year-old individuals were divided into two groups: Group G0 was composed of individuals who required orthodontic treatment, but who did not undergo fixed orthodontic therapy over the study period (n=70); Group G1 was composed of individuals who used a fixed orthodontic appliance for 1 year (n=65). Data collection included a questionnaire and clinical oral examinations (plaque index, gingival index, and dental caries index), performed at baseline and after 1 year.

Gingival enlargement in orthodontic patients: Effect of treatment duration.

Introduction: In this study, we aimed to assess the effect of the duration of fixed orthodontic treatment on gingival enlargement (GE) in adolescents and young adults.

Methods: The sample consisted of 260 subjects (ages, 10-30 years) divided into 4 groups: patients with no fixed orthodontic appliances (G0) and patients undergoing orthodontic treatment for 1 year (G1), 2 years (G2), or 3 years (G3). Participants completed a structured questionnaire on sociodemographic characteristics and oral hygiene habits.

Clinical and radiographic evaluation of indirect pulp treatment in primary molars: 36 months follow-up.

Purpose: To evaluate the clinical and radiographic changes in primary teeth submitted to indirect pulp treatment (IPT) over a 36-month period.

Methods: Thirty-nine primary molars with deep caries, but without preoperative signs and symptoms of irreversible pulpits, received IPT. The teeth were randomly divided into two groups, according to the material used for protection of the dentin-pulp complex: (1) a calcium hydroxide liner (Hydro C) and (2) a gutta-percha sheet.

Clinical and microbiological effect of calcium hydroxide protection in indirect pulp capping in primary teeth.

Purpose: To evaluate clinically and microbiologically the effect of calcium hydroxide (CH) on carious dentin on primary teeth submitted to indirect pulp capping (IPC).

Methods: Twenty 4-7 year-old subjects with 42 treated teeth participated in the study. The treatment consisted of incomplete excavation of the demineralized dentin, application of a CH or gutta-percha (GP) layer and sealing with a resin-based composite for 4-7 months.
