AIM: The aim of the present study was to investigate the presence of selective anaerobic microorganisms in primary root canal infections of symptomatic and asymptomatic non-vital teeth with periapical pathosis using multiplex polymerase chain reaction. METHODS: A total of 100 root canal samples (50 from symptomatic and 50 from asymptomatic teeth) were obtained from patients with primary endodontic infections. DNA extracted from the samples was amplified by using specific primers for the 16S rRNA gene of each bacterium, and semiquantification was done to analyze the prevalence of microorganisms and their correlation to clinical features...

The increasing prevalence of human papilloma virus (HPV)-positive oral tumors can be considered an epidemic. Although the incidence of HPV cervical cancer is decreasing, the incidence of oral cavity and oropharyngeal cancers associated with HPV is increasing. The presence of certain HPV genotypes could be a predictor of future oral cancer lesions, although lesions associated with HPV could be less aggressive and exhibit a higher survival rate. In the present study, we review the most important biologic, clinic, epidemiologic, and prognostic factors associated with HPV infection and oral cancer...

AIM: The aim of the present study was to assess the effect of scaling and root planing (SRP) on periodontal parameters and whole salivary resistin and interleukin (IL)-6 levels in chronic periodontitis (CP) patients with and without obesity. METHODS: Participants were divided into two groups; group 1 included obese and non-obese individuals with CP; and group 2 included obese and non-obese individuals without CP. In both groups, bleeding on probing (BOP) and probing depth (PD) ≥4 mm and whole salivary resistin and IL-6 levels were measured using enzyme-linked immunosorbent assay at baseline and 6 months after SRP...

AIM: The main aim of the present investigation was to evaluate clinical and patient-centered outcomes of supragingival scaling performed with or without the use of 2.5× magnification loupes and illumination. METHODS: A total of 30 patients, divided into three groups, were treated with 2.5× loupes and 2.5× loupes and illumination, and without any magnification device. Full-mouth plaque score percentage (FMPS%) and full-mouth bleeding score percentage (FMBS%) were registered before and after the treatment...

AIM: The aim of the present study was to evaluate the genotoxicity of non-alcoholic mouth rinses on buccal epithelial cells using a micronucleus test. METHODS: A total of 105 patients were selected and randomly divided into five groups. Four different mouth rinses and normal saline were given for 2 weeks' duration, and cytological smears were collected before and after exposure. These smears were subjected to micronucleus (MN) and other nuclear abnormalities (ONA) tests using acridine orange stain, and their frequencies were obtained in 500 buccal epithelial cells...

AIM: The aim of the present study was to investigate the effect of the thin or thick placement of resin-modified glass ionomer cement (RMGIC) lining on the adaptation of resin composite restorations bonded with two types of adhesive. METHODS: Sixty deep occlusal cavities were prepared and divided into two groups: etch-and-rinse adhesive (Single Bond 2) or self-etching adhesive (Clearfil SE Bond). Specimens were further divided into three subgroups: no lining (control), lined with 0...

AIM: Hepatocyte growth factor (HGF) is a multifunctional cytokine with a wide range of actions, and plays a role in periodontal disease (PD) progression. Smoking significantly increases the risk for PD progression. Thus, aim of the present study was to estimate salivary HGF levels of non-smokers and smokers with chronic periodontitis (CP) and to compare its levels before and after therapy. METHODS: A total of 75 participants were recruited and divided into three groups: group 1 included 25 healthy participants, group 2 included 25 non-smokers with CP, and group 3 included 25 smokers with CP...

The action of statins in stimulating bone formation and having other pleiotropic effects, such as anti-inflammatory and immunomodulatory effects, has justified their use as an adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis (CP). The aim of the present study was to evaluate the efficacy of statin delivery as an adjunct to SRP in the treatment of CP. Electronic searches were conducted using the following databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Oral Health Group Trials Register, up until July 2017...

AIM: Elemental mercury is widely used in dentistry as dental amalgam. Hair samples constitute preferred biomarkers to determine the index of mercury exposure. In the absence of any published studies, the aim of the present study was to ascertain the level of mercury in a selected sample of dentists and controls in Sri Lanka. METHODS: Hair samples (.7 g) from dentists working in and around the Colombo district in Sri Lanka (n = 50) and controls (n = 50) were digested with sulfuric acid-potassium permanganate solution, and reduced to metallic mercury with stannous chloride...

AIM: The aim of the present study was to determine the prevalence, location, size, and tooth type of pre-eruptive intracoronal radiolucencies (PEIR) from panoramic radiographs in Thai patients. METHODS: A retrospective study of PEIR was conducted on 1599 panoramic radiographs of 629 Thai males and 970 Thai females with an age range of 4-20 years (average age: 14.0 ± 4.0 years). Each radiograph was reviewed by two calibrated examiners. The age and sex of the patients, location, size, and tooth type of the lesions were recorded...

Alternatives to adrenaline with lignocaine local anesthesia, such as clonidine, have been trialed in various randomized, controlled trials. Therefore, the aim of the present systematic review was to compile the available evidence on using clonidine with lignocaine for dental anesthesia. Electronic databases were searched for eligible studies. A data-extraction form was created, extracted data were analyzed using non-Cochrane mode in RevMan 5.3 software. Heterogeneity between the studies were assessed using the forest plot, I(2) statistics (where >50% was considered to have moderate-to-severe heterogeneity), and χ(2) -test...

AIM: The aim of the present study was to investigate the clinical performance of self-assembling peptide P11 -4 on non-cavitated initial proximal carious lesions 12 months after treatment. METHODS: Twenty-six patients, aged between 18 and 65 years, with 35 carious lesions were included in this practice-based, uncontrolled, prospective case series. The opacity and size of the proximal lesions were evaluated visually at baseline and at day 360 using standardized single-tooth or bite-wing and digital-subtraction radiography...

Antidepressant agents have anti-inflammatory functions that could be interesting as adjuvants in periodontal therapy. The aim of the present study was to analyze the effect of antidepressive drugs in the management of periodontal disease. The MEDLINE, Scopus, Embase, LILACS, and SciELO databases were searched. To be included, the studies had to be experimental studies; randomized, controlled; double-blinded; or blinded studies. A total of 565 articles were initially searched, of which five were selected for the systematic review...
