One hundred dental surgeons practising in western France were immunized against hepatitis B virus, using the same batch of HEVAC B vaccine from the Pasteur Institute. The vaccine was very well tolerated. Seroconversion at 10 m IU/ml was 94% after 3 injections and 98% after the booster dose. From a kinetic study of anti-HBs antibodies we were able to determine different levels of post-immunization serological response and to classify responders as very good, good and fairly good. The effectiveness of the booster dose was manifest after 10 days. In view of the efficacy and safety of this vaccine, confirmed by other studies in sanitary personnel, we do not hesitate to recommend it to dental surgeons exposed to the disease.

The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset-with data collected between 2020 and 2022 -to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions.

Introduction: The cant of the occlusal plane in the frontal plane reflects facial asymmetry. Its treatment requires close collaboration between the orthodontist and the maxillofacial surgeon. In case of mild cant, treatment consists in coordination of dental arches followed by mandibular osteotomy.

Objective: This study evaluated ResNet-50 and U-Net models for detecting and segmenting vertical misfit in dental implant crowns using periapical radiographic images.
Methods: Periapical radiographs of dental implant crowns were classified by two experts based on the presence of vertical misfit (reference group). The misfit area was manually annotated in images exhibiting vertical misfit.

Objectives: This experimental study compared the accuracy of implant insertion using the free-hand (FH) technique, static computer-aided surgery (S-CAIS), or dynamic computer-assisted surgery (D-CAIS) and to evaluate the correlation of learning curves between surgeons' experience and surgical time.
Materials And Methods: Thirty-six models were randomly assigned to three groups (FH, n = 12; S-CAIS, n = 12; D-CAIS, n = 12). Each model was planned to receive four implants in the maxillary anterior and posterior regions.

An umbilical granuloma (UG) is one of the most common umbilical anomalies seen in infants, mostly due to delayed cord separation. It is usually treated with silver nitrate; however, topical application of silver nitrate can cause chemical burns, creating concern among parents. We present a similar case in a two-month-old baby boy with a giant UG, which was treated with topical silver nitrate application, producing significant chemical burns around the umbilicus and on the anterior abdominal wall.
