Unveiling the correlation between in vivo endodontic reciprocate instrumentation and crack formation.

Introduction: Dentinal microcracks have been supposedly associated with unrestorable vertical root fractures and consequently long-term treatment failure. This study aimed to investigate whether in vivo root canal instrumentation in mandibular incisors with vital pulps causes dentinal microcracks using two different irrigating solutions.

Methods: Five patients with four vital mandibular incisors indicated for extraction were included.

Oral candidiasis in liver transplant patients: species identification and antifungal susceptibility profile.

Objective: This study aimed to verify oral candidiasis, identify the causative species, and investigate the antifungal susceptibility of yeasts isolated from liver transplant patients.

Methods: A descriptive analysis of 97 patients who underwent liver transplantation was conducted at a hospital. Two clinical examinations (Collections A and B) of the oral cavity were performed.

Quality assessment of randomised controlled trials in oral and maxillofacial surgery.

Randomised controlled trials are the best way to study the evaluation of treatments. We have evaluated the quantity and quality of clinical trials in three of the main journals in the specialty of oral and maxillofacial surgery between January 2010 and December 2016, using a scientometric analysis, and evaluation by the Jadad scale. In this period, 303 randomised controlled trials (5% of the total) were identified; the largest number of studies were from Asia (45%) followed by Europe (32%).

Four-year clinical prospective follow-up of resin composite restoration after selective caries removal using Er:YAG laser.

Objectives: The aim of this study was to longitudinally evaluate, after a 4-year period, the clinical longevity of composite resin restoration compared to the baseline, after selective caries removal in permanent molars using Er:YAG laser or bur preparation with biomodification of dentin with the use of chlorhexidine.

Methods: Selective caries removal was performed on 80 teeth of 20 individuals who each had at least four active carious lesions. These lesions, located on occlusal surfaces of permanent molar counterparts, were removed using (i) Er:YAG laser biomodified with chlorhexidine, (ii) Er:YAG laser and application of deionized water, (iii) bur preparation biomodified with chlorhexidine, and (iv) bur preparation and application of deionized water.

Parent-child interaction and stimulation in early life can be related to caries in primary dentition? Hypotheses from a life-course approach.

Dental caries has common risk factors with impairments in growth, cognitive development and child general health. Identifying socioeconomic contexts and parental behaviors in early life that may be associated with negative outcomes in the child's future and their causal mechanisms can contribute to planning early interventions. Therefore, the aim of this paper is to propose and discuss possible ways to explain how early childhood stimulation may be associated with future oral health status, based on the life-course theory of chain-of-risk model and accumulation of risk model.

Accuracy of dental development for estimating the pubertal growth spurt in comparison to skeletal development: a systematic review and meta-analysis.

Objectives: This study aimed to search for scientific evidence concerning the accuracy of dental development for estimating the pubertal growth spurt.

Methods: It was conducted according to the statements of PRISMA. An electronic search was performed in six databases, including the grey literature.

Clinical evaluation of composite restorations in Er:YAG laser-prepared cavities re-wetting with chlorhexidine.

Objectives: The objective of this study was to evaluate longitudinally the composite restorations, performed in cavities prepared by Er:YAG or conventional bur, and dentin re-wetting with water or chlorhexidine.

Materials And Methods: Twenty individuals with four active caries with cavitation reaching the dentin located on the occlusal surface of molars counterparts are selected. The teeth of each individual were randomly assigned into four groups: (I) Er:YAG laser (260 mJ/4 Hz) re-wetting with chlorhexidine, (II) Er:YAG laser (260 mJ/4 Hz) re-wetting with deionized water, (III) conventional method re-wetting with chlorhexidine, and (IV) conventional method re-wetting with deionized water.
