Is There Variation in the Morphology of the Frontal Sinus in Individuals with Different Craniofacial Patterns? A Systematic Review with Meta-Analysis.

To evaluate differences in the morphology of the frontal sinus in adolescents and adults with different craniofacial patterns, searches up to April 2024 were conducted in six databases and other information sources to identify observational studies. Study selection, data extraction, and quality assessment using the NOS scale were performed independently by two reviewers. Random effects meta-analyses were conducted to estimate the difference in frontal sinus measurements between different craniofacial skeletal patterns (α = 0.

Nutritional Status is Associated with Permanent Tooth Eruption in a Group of Brazilian School Children.

The present study aimed to investigate the association between nutritional status with delayed tooth eruption (DTE). Oral examination was performed in schoolchildren (8-11 years old), and DTE was defined by absence of dental gingival emergence or when primary tooth was still present in the oral cavity after the expected time. BMI -score of each child were collected and nutritional status was defined.

Vitamin D receptor FokI and BglI genetic polymorphisms, dental caries, and gingivitis.

Background & Aim: To investigate the association between the genetic polymorphisms FokI (rs2228570) and BglI (rs739837) in vitamin D receptor (VDR) with dental caries and gingivitis susceptibility.

Design: This study included 353 Brazilian children (8 to 11 years old). Dental caries was assessed using ICDAS (International System for Detection and Assessment of Carious Lesions) and gingival bleeding using Community Periodontal Index (CPI).

Audiovisual distraction methods for anxiety in children during dental treatment: A systematic review and meta-analysis.

Background: Dental treatment can cause symptoms such as fear and anxiety. Audiovisual distraction (AD) is a simple and low-cost technique that does not interfere with the dental treatment.

Aim: The aim of this study was to perform a systematic review and meta-analysis to evaluate the effectiveness of AD methods for children who experience anxiety during dental treatment.

Posttraumatic displacement management: lateral luxation and alveolar bone fracture in young permanent teeth with 5 years of follow-up.

Dental trauma is an important public health problem due to high prevalence and associated limitations. The external impact accounting for trauma may result in different injury types to teeth and supporting structures. This paper describes a clinical case of tooth trauma in an 8-year-old patient exhibiting the displacement of three permanent teeth with open root apexes.

Effect of acidic challenge preceded by food consumption on enamel erosion.

Objectives: This in vitro study aimed to evaluate the effect of food consumption followed by acidic challenge on enamel erosion.

Methods: Seventy-five enamel blocks obtained from bovine teeth were divided randomly into five groups (n=15 per group): GI - erosion with previous immersion in milk; GII - erosion with previous immersion in cheese extract; GIII - erosion with previous immersion in liver extract; GIV - erosion with previous immersion in broccoli extract; and GV - erosive effect of cola drink (control). Over 24 h, the slabs were submitted to 3 pH-cycles, each consisting of immersion in the studied food (GI to GIV) for 5 min followed by immersion in a cola drink for 5 min, and subsequently, the slabs were stored in artificial saliva (110 min).

Histopathological evaluation of root canal filling materials for primary teeth.

This study aimed to assess the response of apical and periapical tissues of dogs' teeth after root canal filling with different materials. Forty roots from dogs' premolars were prepared biomechanically and assigned to 4 groups filled with: Group I: commercial calcium hydroxide and polyethylene glycol-based paste (Calen) thickened with zinc oxide; Group II: paste composed of iodoform, Rifocort and camphorated paramonochlorophenol; Group III: zinc oxide-eugenol cement; Group IV: sterile saline. After 30 days, the samples were subjected to histological processing.
