Position of digitally guided implants in completely edentulous maxillae by using a modified double-scan and overlap of three digital surface protocol.

Statement Of Problem: In patients with a completely edentulous maxilla, the variability in resilience and mucosal thickness and the lack of teeth and rigid supporting structures may lead to poor adaptation of the surgical guide and significant variation in the definitive implant position. Whether a modified double-scan technique with overlap of surfaces will improve implant placement is unclear.

Purpose: The purpose of this prospective clinical study was to evaluate the 3-dimensional position and the correlation of 6 dental implants in participants with a completely edentulous maxilla using a mucosa-supported flapless surgical guide designed with 3 matched digital surfaces obtained with a modified double-scan protocol.

Chilean Patients' Perception of Their Oral Health-Related Quality of Life After Bichectomy.

Objective: To describe the quality of life associated with oral health in patients who have had bichectomy surgery in Chile using the Spanish version of the health-Related Quality of Life instrument (HRQOL-sp).

Material And Methods: We designed a cross-sectional study. The HRQOL-sp scale was administered to dental patients in a private clinic who had bichectomy surgery between December 2020 and June 2021.

Chemotherapy as a risk factor for caries and gingivitis in children with acute lymphoblastic leukemia: A retrospective cohort study.

Background: Dental and oral anomalies are among the most common long-term side effects of childhood cancer therapy.

Aim: To evaluate chemotherapy as a risk factor for caries lesions and gingivitis in children with acute lymphoblastic leukemia (ALL) treated with the ALL IC-BFM 2009 chemotherapy protocol.

Design: A retrospective cohort study was designed.

Leukocyte and Platelet-Rich Fibrin Have Same Effect as Blood Clot in the 3-Dimensional Alveolar Ridge Preservation. A Split-Mouth Randomized Clinical Trial.

Purpose: Leukocyte- and platelet-rich fibrin (L-PRF) has been used for alveolar ridge preservation (ARP) in postextraction tooth sockets. However, current reports have measured its effectiveness in linear measurements of 3-dimensional ridge preservation. The purpose of this study was to determine the effectiveness of the use of L-PRF filling versus natural clot blood healing in ARP according to the clinical, radiographic, and volumetric measurements of postextraction tooth sockets.

Effect of music at 432 Hz and 440 Hz on dental anxiety and salivary cortisol levels in patients undergoing tooth extraction: a randomized clinical trial.

Objective The aim of this study was to compare the effects of music at 432 Hz, 440 Hz, and no music on the clinical perception of anxiety and salivary cortisol levels in patients undergoing tooth extraction. Methodology A parallel-group randomized clinical trial was conducted. Forty-two patients (average age: 23.

Effect of warming anesthetic on pain perception during dental injection: a split-mouth randomized clinical trial.

Background: The purpose of this study is to determine the effectiveness of warming anesthesia on the control of the pain produced during the administration of dental anesthesia injection and to analyze the role of Transient Receptor Potential Vanilloid-1 nociceptor channels in this effect.

Patients And Methods: A double-blind, split-mouth randomized clinical trial was designed. Seventy-two volunteer students (22.

Reliability and validity of measuring scale for postoperative complications in third molar surgery.

Background: Third molar removal surgery is the most frequently performed surgery in the oral and maxillofacial field with a wide range of items in the quantification of postoperative complications. For their measure, in 2014 a previous scale design was presented. The aim of this study was to determine the reliability and validity of a scale designed to measure and quantify postoperative complications in third molar surgery (TMS).

[The impact of the orthopedic surgeons' attire on patient preferences].

Background: The formal appearance of health care professionals may influence their trustworthiness.

Aim: To determine the effect of the orthopedic surgeon's attire on patients' perceptions of credibility and reliability of professionals.

Material And Methods: In a cross-sectional design, 351 patients (mean age 43 ± 17 years, 62% males) from the Department of Orthopedics and Traumatology of a Chilean regional hospital in southem of Chile were chosen to complete a questionnaire of attire preferences, in which five photographs with male and female orthopedic surgeons appeared (executive, formal attire, informal attire, scrubs and casual clothing).

Use of Electronic Versus Print Textbooks by Chilean Dental Students: A National Survey.

Electronic textbooks have become available in recent decades as replacements or alternatives for print versions. The aim of this descriptive cross-sectional study was to evaluate the use of electronic versus print textbooks by Chilean dental students. The target population was students from 14 Chilean dental schools.

Skin and mucosal ischemia as a complication after inferior alveolar nerve block.

The anesthetic block of the inferior alveolar nerve (IAN) is one of the most common techniques used in dental practice. The local complications are due to the failures on the anesthetic block or to anatomic variations in the tap site such as intravascular injection, skin ischemia and ocular problems. The aim of this article is to present a case and discuss the causes of itching and burning sensation, blanching, pain and face ischemia in the oral cavity during the IAN block.

Chilean patients' perception of oral health-related quality of life after third molar surgery.

Objective: To describe the perception of the quality of life in oral health based on the Health-Related Quality of Life instrument in its Spanish version (HRQOL-sp) in Chilean patients with third molar extraction surgery.

Patients And Methods: A cross-sectional study. The HRQOL-sp was administered to dental patients at the Public Hospital in Rio Bueno in southern Chile treated for unilateral third molar extraction between March and June 2014.
