Influence of design implant and apical depth in post-extraction sockets: an in vitro simulated study.

Background: Implant design and apical stability are principal parameters involved in achieving successful primary stability. Using polyurethane models to simulate post-extraction sockets, we investigated the effects of using differing blade designs on the primary stability of tapered implants and the impact of apical depth.

Method: Six polyurethane blocks were used to simulate post-extraction pockets.

Restoration of a malformed primary incisor using digital technology in a pediatric patient with congenital Zika virus syndrome: A case report.

Zika virus congenital syndrome (ZVCS) is a congenital viral infection resulting from the transmission of the Zika virus (ZV) to the fetus during pregnancy. This report describes a clinical case involving a 20-month-old female child with ZVCS, who presented with systemic changes related to the syndrome, such as microcephaly, arthrogryposis, ocular and auditory changes, and oral changes such as delayed dental eruption, ogival (high-arched) palate, short lip frenum, and altered morphology of a superior primary incisor. For esthetic and functional rehabilitation of the oral health of this child, an indirect composite resin restoration was performed using intraoral digital scanning technology.

Radiographic evaluation of dental anomalies in patients with congenital Zika virus syndrome.

Numerous studies have reported abnormalities in the development of oral structures in congenital infections that also involve microcephaly. In this context, it is necessary to identify possible dental anomalies of shape and/or number in patients with Zika virus syndrome using radiography. The study population consisted of 35 children born with congenital ZIKV who underwent intraoral radiographic examinations for 24 consecutive months.

Distance learning during social seclusion by COVID-19: Improving the quality of life of undergraduate dentistry students.

Background: Social isolation is ongoing worldwide with the aim to stem the spread of the novel coronavirus SARS-CoV-2 responsible for the COVID-19 pandemic. However, social isolation leads to significant psycho-emotional changes. This study aimed to assess the effect of distance education (DE) activities implemented due to social isolation, on the quality of life of undergraduate dentistry students.

Microtomographic analysis of the effect of sodium alendronate on orthodontic movement in rats.

Objective: To evaluate the effect of sodium alendronate on orthodontic tooth movement in rats using microtomographic analysis.

Settings And Sample Population: Thirty male Wistar rats (Rattus norvegicus) were divided into three groups of 10 rats and administered saline (control), 1 mg/kg sodium alendronate or 6 mg/kg sodium alendronate, respectively.

Materials And Methods: The drug was administered once per week for 5 weeks by gavage.

Internal configuration of maxillary molars in a subpopulation of Brazil's Northeast region: A CBCT analysis.

The present study aimed to evaluate the internal configuration of the maxillary molars of a population from the Northeast region of Brazil. Cone-beam computed tomography (CBCT) exams from 512 patients (1501 teeth) were evaluated regarding the anatomical configuration of the root canal system, according to Vertucci's classification. The images were obtained using a Prexion 3D scanner operating at 90 kVp and 4 mA.

Clinical and x-ray oral evaluation in patients with congenital Zika Virus.

Objective: The aim of this study was to investigate possible malformations in the soft, bone and/or dental tissues in patients with congenital Zika Virus (ZIKV) by clinical and x-ray evaluation.

Methodology: Thirty children born with ZIKV and 30 children born without ZIKV (control group) were included in the study. Patients were evaluated over 24 consecutive months according to the variables: sex, age, cleft palates, soft tissue lesions, alveolar ridge hyperplasia, short labial and lingual frenums, inadequate posture of the lingual and perioral muscles at rest, micrognathia, narrow palatine vaults, changes in the teeth shape and/or number, sequence eruption, spasms, seizures and eruption delay were evaluated.

The effect of orthodontic separator and short-term fixed orthodontic appliance on inflammatory mediators and somatosensory function.

Background: Although inflammation can alter cytokines release and nerve function, it is not yet fully established if orthodontic-induced inflammation can cause significant extraoral trigeminal somatosensory alterations and release of inflammatory chemical mediators.

Objective: The primary aim of this study was to investigate the impact of orthodontic separator and short-term fixed orthodontic appliance on the extraoral trigeminal somatosensory function and concentrations of cytokines in the gingival crevicular fluid (GCF).

Methods: Twenty-two female patients were evaluated as follow: baseline, 24 hour-after elastomeric separator (-aES), 24 hour- and 1 month-after bonding brackets (-aBB) at both arches.

External root resorption of the second molar associated with third molar impaction: comparison of panoramic radiography and cone beam computed tomography.

Purpose: The aim of the present study was to compare panoramic radiography and cone beam computed tomography (CBCT) for the assessment of external root resorption (ERR) of second molars associated with impacted third molars. In addition, the prevalence of ERR in second molars and the inclinations of the third molars more associated with ERR were investigated in both imaging methods.

Materials And Methods: The sample consisted of 66 individuals with maxillary and mandibular impacted third molars (n = 188) seen on panoramic radiographs and CBCT images.

Clinical, tomographic aspects and relevance of torus palatinus: case report of two sisters.

Despite the nomenclature suggested to be a tumor, torus palatinus (TP) is an overgrowth of the bone in the palatal region and represents an anatomic variation. Its prevalence varies among the population studied and its etiology is still unclear; however, it seems to be a multifactorial disorder with genetics and environmental involvement. Surgical removal of the TP is indicated in the following circumstances: (1) deglutition and speech impairment, (2) cancer phobia, (3) traumatized mucosa over the torus, and (4) prosthetic reasons.

Enhancement cone beam computed tomography filters improve in vitro periimplant dehiscence detection.

Objective: To investigate whether cone beam computed tomography filters would improve periimplant dehiscence detection.

Study Design: A hundred titanium implants were placed in bovine ribs in which defects simulating periimplant dehiscence had previously been created. After images acquisition, three oral radiologists assessed them with and without the following filters: Angio Sharpen high 5 × 5, Shadow, Sharpen 3 × 3, Sharpen Mild, and Smooth.

Clinical effect of a gel containing Lippia sidoides on plaque and gingivitis control.

Objective: This parallel controlled clinical trial evaluated the effect of a gel containing Lippia sidoides essential oil on plaque and gingivitis control.

Methods: Thirty patients (n=30) were randomly selected and allocated into three groups: Lippia sidoides (LS, n=10), chlorhexidine (CLX, n=10) or placebo (control, n=10). Plaque and bleeding index were recorded at baseline and after three months.
