INTRODUCTION: The impact of socioeconomic status (SES) on tooth mineralization has seldom been evaluated. This is important because SES can be used as a proxy for quantifying factors in the environmental that can impact mineralization but that can be difficult to measure directly, such as nutrition. OBJECTIVE: The objective of this study was to examine the effects of SES on third molar mineralization, using a sample of children, adolescents and young adults from Porto, Portugal...

INTRODUCTION: Third molar surgery (TMS) became a routine, safe office procedure with generally predictable outcomes and relative low cost. It affects quality of life (QOL) of patients by causing considerable pain, swelling and trismus; by changing what people eat, their speech in the first few days after surgery. The purpose of the present study was to improve QOL of patient after lower TMS by injecting single dose 8 mg submucosal dexamethasone. MATERIALS AND METHODS: Forty healthy adult subjects of either gender underwent surgical removal of the lower impacted third molar under local anaesthesia and after being randomly assigned to receive either 8 mg dexamethasone submucosal injection or normal saline injection in proximity to surgical site...

INTRODUCTION: When the mandibular permanent second molar becomes impacted, it is identified as a malocclusion that needs treatment as it often leads to unwanted complications such as caries and periodontitis of the adjacent permanent first molar. Other less common complications include root resorption of the adjacent first molar root or continued root development to be in close proximity to the inferior dental alveolar nerve. MATERIALS AND METHODS: This paper seeks to differentiate various levels of severity of impaction and review treatment options that are considered clinically available for the proper management of the impacted mandibular permanent second molar...

AIM: To investigate the role of cAMP response element-binding protein (CREB) in the regulation of odonto/osteogenic differentiation of stem cells from the apical papilla (SCAPs). METHODOLOGY: SCAPs were obtained from human impacted third molars (n=15). Isolated SCAPs were transfected with CREB overexpressing/silenced lentivirus. Transfected cells were stained with alizarin red to investigate mineralized nodule formation. The expression of the mineralization-related genes alkaline phosphatase (ALP), collagen type I (Col I), runt-related transcription factor 2 (RUNX2), osterix (OSX), and osteocalcin (OCN), was determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR)...

Minimally invasive endodontics emphasizes preservation of a maximal amount of healthy tooth tissue. However, whether the tooth structure preserved by minimally invasive endodontics can maintain higher fracture resistance is unclear. This study aimed to compare the biomechanics on teeth after minimally invasive (MI) preparation and straight-line (SL) preparation using finite element analysis. Six finite element analysis models of a mandibular first molar were constructed and divided into two groups (MI and SL)...

Factors associated with the diagnosis, aetiology, and treatment of mandibular fractures occurring during the postoperative period following the removal of a lower third molar are discussed. The following databases were searched using specific key words: PubMed/MEDLINE, LILACS, Embase, and Scopus. The search yielded 124 cases. Sex, age, side, tooth position and angulation, bone impaction, relationship between the tooth and the inferior alveolar nerve, local pathological conditions, aetiology of the fracture, symptomatology, and time between surgery and fracture, as well as any displacement of the fracture and the treatment of the fracture, were evaluated...

PURPOSE: Iatrogenic fracture of mandible (IFM) associated with exodontia though rare, they do occur with an incidence ranging from 0.0034 to 0.0075 %. Most of the data is in the form of case reports or a small case series. This is an attempt to amass the data available in literature since the last 62 years. The purpose of this meta-analysis is to identify the etiologies and risk factors leading to IFM associated with exodontia and also the measures to minimize the complication. METHODS: Articles published between 1953 and 2015 were searched in Medline database...

The extraction of an impacted third molar violates the surrounding soft and bony tissues. The surgeon's access to the tooth, for which there are various surgical approaches, has an important impact on the periodontium of the adjacent second molar. The aim of this review was to analyze the relationships between the different flap techniques and postoperative periodontal outcomes for the mandibular second molars (LM2) adjacent to the impacted mandibular third molars (LM3). An electronic search of MEDLINE and other databases was conducted to identify randomized controlled trials fulfilling the eligibility criteria...

In prolonged chronic osteomyelitis, chronic inflammation and low-grade infections can result in new periosteal bone formation. Chronic osteomyelitis with proliferative periostitis (traditionally termed Garré's sclerosing osteomyelitis) mainly affects children and young adults. Here, we present two rare cases of an 11-year-old and a 12-year-old patient with suppurative chronic osteomyelitis with proliferative periostitis without any definitive infection source, such as dental caries or periodontitis. The source of infection was likely to be related to the development of a lower right third molar germ with follicular space widening...
