The aims of this study were to 1) determine if continuous eruption occurs in the maxillary teeth, 2) assess the magnitude of the continuous eruption, and 3) evaluate the effects of continuous eruption on the different periodontal parameters by using data from the population-based cohort of the Study of Health in Pomerania (SHIP). The jaw casts of 140 participants from the baseline (SHIP-0) and 16-y follow-up (SHIP-3) were digitized as 3-dimensional models. Robust reference points were set to match the tooth eruption stage at SHIP-0 and SHIP-3. Read More

Objective: To provide a comparative baseline for future studies of oral pathology in domestic livestock and to better understand connections between lesion prevalence and biological context in past animal populations.

Materials: Over 1600 sheep and cattle mandibles recovered from archaeological sites in England between 500 and 1300 CE.

Methods: A comprehensive investigation of periodontal disease was conducted based on four characteristics: dental calculus; periosteal new bone formation; alveolar recession; and ante-mortem tooth loss. Read More

Introduction: The early diagnosis and interception of potential maxillary canine impaction is the most desirable approach for correcting their path of eruption. However, there is still a lack of evidence regarding the effect of rapid maxillary expansion (RME) on labially impacted canines. This study aimed to investigate the age-related effect of RME on labially impacted maxillary canines in order to reduce the risk of their impaction in the mixed dentition and to examine the proper timing of interceptive treatment.

Cleft Palate Craniofac J 2021 Feb 25:1055665621995047. Epub 2021 Feb 25.

Division of Plastic Surgery, Department of Surgery, University of California, San Diego, La Jolla, CA, USA.

Background: Alveolar bone grafting is utilized to manage alveolar clefts in patients with cleft lip and palate. However, the timing of bone grafting is variable with conflicting evidence supporting the use of primary alveolar bone grafting (PABG) in clinical practice.

Primary Aim: To provide a qualitative systematic review analysis of long-term outcomes after PABG. Read More

Department of Morphology, Genetics, Orthodontics and Pediatric Dentistry, São Paulo State University (Unesp), Araraquara School of Dentistry, Araraquara, São Paulo, Brazil.

Background: The second permanent molar plays an important role when considering the extractions of first permanent molars severely affected by Molar-Incisor Hypomineralization (MIH).

Aim: To assess the association between MIH and enamel hypomineralization of second permanent molars in terms of presence and severity.

Design: In this retrospective cross-sectional study, permanent teeth were evaluated in 453 patients between the ages of 13 and 16 at a dental clinic, using intraoral photographs. Read More
