To evaluate, in vitro, the effects of ionizing radiation on mechanical and micro-morphological properties enamel dentin permanent teeth. Enamel microhardness (n = 12 hemi-sections) was evaluated at three depths (superficial, middle deep) prior to (control) after every 10 Gy dose up a cumulative 60 by means longitudinal microhardness. Data were analyzed using two-way analysis variance Tukey's test significance level 5%. morphology assessed scanning electron microscopy (SEM) for...
To evaluate the effects of radiation therapy on deciduous teeth.The enamel and dentin microhardness (n = 12) was evaluated at 3 depths, both before (control) after each 10 Gy irradiation up to a dose 60 Gy. The morphology via scanning electron microscopy (SEM) 8). data were analyzed using two-way analysis variance (ANOVA) Tukey's test (α 5%).The microhardness, as whole, increased (p < 0.05) (211.4 KH), mostly in superficial enamel. There significant difference between values nonirradiated...
The host defense mechanisms are not well developed in neonates. aim of this study was to evaluate the dynamics microbial colonization oral cavity newborns. Eighty-one samples microbiota were obtained from 51 healthy newborns 10 min 53 h after birth by gently rubbing sterile swabs onto surface tongue, cheek mucosa, alveolar process and palate. After microbiological processing, counting colony forming units streptococci, staphylococci Gram-negative aerobic bacilli performed. Between 8 h,...
Background: Artificial intelligence (AI) can be a tool in the diagnosis and acquisition of knowledge, particularly dentistry, sparking debates on its application clinical decision-making. Objective: This study aims to evaluate accuracy, completeness, reliability responses generated by Chatbot Generative Pre-Trained Transformer (ChatGPT) 3.5 dentistry using expert-formulated questions. Materials methods: Experts were invited create three questions, answers, respective references according...
This study evaluated in vitro the antibacterial activity of 4 root canal filling materials for primary teeth - zinc oxide and eugenol cement (ZOE), Calen paste thickened with (Calen/ZO), Sealapex sealer EndoREZ against 5 bacterial strains commonly found endodontic infections (Kocuria rhizophila, Enterococcus faecalis, Streptococcus mutans, Escherichia coli Staphylococcus aureus) using agar diffusion test (agar-well technique). paste, 1% chlorhexidine digluconate (CHX) distilled water served...
This study aimed to assess the response of apical and periapical tissues dogs' teeth after root canal filling with different materials. Forty roots from premolars were prepared biomechanically assigned 4 groups filled with: Group I: commercial calcium hydroxide polyethylene glycol-based paste (Calen®) thickened zinc oxide; II: composed iodoform, Rifocort® camphorated paramonochlorophenol; III: oxide-eugenol cement; IV: sterile saline. After 30 days, samples subjected histological processing....
Mucocele is a benign lesion occurring in the buccal mucosa as result of rupture salivary gland duct and consequent outpouring mucin into soft tissue. It usually caused by local trauma, although many cases etiology uncertain. more commonly found children young adults, most frequent site lower inner portion lips. Fibroma, on other hand, tumor fibrous connective tissue that can be considered reactionary hyperplasia response to trauma irritation. They present hard consistency, are nodular...
Abstract Aim To evaluate the effect of carbodiimide (EDC) and chlorhexidine (CHX) on bond strength (BS) resin cement to root dentine teeth submitted radiotherapy. Methodology One hundred twenty extracted maxillary canines were selected assigned 2 groups ( n = 60): nonirradiated irradiated (30 cycles Gy, total 60 Gy). Roots lengths standardized, canals prepared filled. Post spaces then prepared, samples redistributed according treatment 20): saline solution (SF); CHX 2%; or EDC 0.5M. After...
This study evaluated the response of subcutaneous connective tissue BALB/c mice to root filling materials indicated for primary teeth: zinc oxide/eugenol cement (ZOE), Calen paste thickened with oxide (Calen/ZO) and Sealapex sealer. The (n=102) received polyethylene tube implants materials, thereby forming 11 groups, as follows: I, II, III: Calen/ZO 7, 21 63 days, respectively; IV, V, VI: VII, VIII, IX: ZOE X XI: empty 7 respectively. biopsied tissues were submitted histological analysis...
The objective of this in vitro study was to evaluate the antimicrobial effect toothpastes containing natural extracts, chlorhexidine or triclosan. effectiveness extracts (Parodontax®), 0.12% (Cariax®), 0.3% triclosan (Sanogil®) fluoride (Sorriso®, control) evaluated against yeasts, Gram-positive and Gram-negative bacteria using disk diffusion method. Water used as a control. Disks impregnated with were placed Petri dishes culture media inoculated 23 indicative microorganisms by pour plate...
Abstract Aim To characterize the formation and progression of experimentally induced periapical lesions in teeth MyD88 knockout (MyD88 KO ) mice compared with wild‐type ( WT mice. Methodology Periapical were mandibular first molars 30 After 7, 21 42 days, animals euthanized mandibles subjected to histotechnical processing. Histological sections stained haematoxylin eosin HE ), TRAP histoenzymology, Brown Brenn staining immunohistochemistry RANK , RANKL OPG ). Data statistical analysis by...
Abstract Aim To evaluate the bond strength and adhesive interface between several resin cements root dentine immediately 6 months after radiotherapy. Methodology Sixty maxillary canines were selected randomly assigned to two groups ( n = 30): one group was not irradiated other subjected a cumulative radiation dose of 60 Gy. The teeth sectioned obtain roots 16 mm long canals prepared with Reciproc system (R50) filled using lateral condensation technique an epoxy sealer. Each divided into...
The radiotherapy can directly affect the bond strength of adhesive materials, interfering in prognosis restorative treatments, which may be caused by chemical changes dentin structure.Twenty inferior homologues premolars were distributed 2 groups (in vitro study) (n = 10): nonirradiated and irradiated. specimens submitted to analysis phosphate (ν1 PO43- ;ν2 ;ν4 ), carbonate (ν3 CO32- amide I, CH2 , III, I/III ratio confocal Raman spectroscopy. Data statistical (T test, P < .05).In intracanal...
Introduction Molar-incisor hypomineralization (MIH) is a qualitative defect of dental enamel that affects one or more permanent first molars, with without involvement the incisor teeth. This condition leads to challenges care and treatment planning. Aim Based on hypothesis children who have MIH possibly present alterations in postural masticatory activities considering absence studies investigating these parameters, study evaluated functionality stomatognathic system mentioned aspects....
