Abstract
Black hairy tongue (BHT) is a lesion in which the filiform papillae of the tongue are significantly extended by hyperkeratosis, thereby giving the tongue a hairy appearance. Here, we report two rare cases of children with BHT and tooth discoloration caused by antimicrobial agents. Case 1: A four-year-old female patient received intravenous linezolid after spinal surgery, and BHT developed on day eight of treatment. Subsequently, the patient developed teeth discoloration. Linezolid was continually administered for 50 days, and BHT and teeth discoloration improved 10 days after the end of linezolid treatment. Case 2: A two-year-old male patient with a brain abscess received intravenous meropenem and vancomycin. On the fourth day of treatment, BHT developed, and teeth discoloration was subsequently observed. Antibiotic therapy was continued for 82 days, and BHT and tooth discoloration improved 20 days after the treatment was discontinued.

Prenatal exposure to persistent organic pollutants and molar-incisor hypomineralization among 12-year-old children in the French mother-child cohort PELAGIE. ENVIRONMENTAL RESEARCH 2023; 231:116230. [PMID: 37236387 DOI: 10.1016/j.envres.2023.116230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 05/17/2023] [Accepted: 05/23/2023] [Indexed: 05/28/2023]
Abstract
BACKGROUND Exceptional episodes of exposure to high levels of persistent organic pollutants have already been associated with developmental defects of enamel among children, but knowledge is still scarce concerning the contribution of background levels of environmental contamination. METHODS Children of the French PELAGIE mother-child cohort were followed from birth, with collection of medical data and cord blood samples that were used to measure polychlorinated biphenyls (PCBs), organochlorine pesticides (OCs), and perfluorinated alkyl substances (PFASs). At 12 years of age, molar-incisor hypomineralization (MIH) and other enamel defects (EDs) were recorded for 498 children. Associations were studied using logistic regression models adjusted for potential prenatal confounders. RESULTS An increasing log-concentration of β-HCH was associated with a reduced risk of MIH and EDs (OR = 0.55; 95% CI, 0.32-0.95, and OR = 0.65; 95% CI, 0.43-0.98, respectively). Among girls, intermediate levels of p,p'-DDE were associated with a reduced risk of MIH. Among boys, we observed an increased risk of EDs in association with intermediate levels of PCB 138, PCB 153, PCB 187, and an increased risk of MIH with intermediate levels of PFOA and PFOS. CONCLUSIONS Two OCs were associated with a reduced risk of dental defects, whereas the associations between PCBs and PFASs and EDs or MIH were generally close to null or sex-specific, with an increased risk of dental defects in boys. These results suggest that POPs could impact amelogenesis. Replication of this study is required and the possible underlying mechanisms need to be explored.

[PMID: 37584264 DOI: 10.1080/14740338.2023.2247962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 07/18/2023] [Accepted: 08/09/2023] [Indexed: 08/17/2023]
Abstract
BACKGROUND The association between dental problems and sublingual/buccal buprenorphine is unclear. We conducted an analysis of dental adverse drug reactions reported with sublingual/buccal buprenorphine in VigiBase®, the pharmacovigilance database of the World Health Organization. RESEARCH DESIGN AND METHODS We performed disproportionality analyses to compare the reporting rates of dental problems with sublingual/buccal buprenorphine, compared to other buprenorphine formulations and methadone. Significant signals were considered if the lower boundary of the 95% confidence interval of the Reporting Odds Ratio (ROR) was > 1; cases were ≥ 3 and p-value <0.05. We conducted sensitivity analyses by calculating the ROR according to the reporter's qualification and the reporting continent (United States of America and Europe). RESULTS We included 30,769 reports with all buprenorphine forms. We found 20 cases of dental problems with sublingual/buccal buprenorphine. Sublingual/buccal buprenorphine was associated with an overreporting of dental problems compared to other buprenorphine formulations (ROR = 15.10; 95% CI [7.50-30.39]; p < 0.005) and compared to methadone (ROR = 6.02; 95% CI [3.21-11.30]; p < 0.005). Overreporting of dental problems was consistent in sensitivity analyses, except in Europe compared with other buprenorphine formulations and with methadone. CONCLUSIONS Sublingual/buccal buprenorphine might increase the risk of reporting dental problems. However, these results do not modify the benefits of sublingual/buccal buprenorphine in the treatment of opioid use disorders.

Abstract
INTRODUCTION Regenerative endodontic procedures (REP) provide conditions for the continuity of apical formation and increase of the dentin walls thickness, being a useful technique to resume root development of necrotic teeth with incomplete apex. This study aimed to evaluate the coronal discoloration promoted by a new intracanal calcium silicate-based dressing and compare it with other intracanal dressings used in REP. METHODS Sixty bovine incisors were prepared to simulate teeth with incomplete apexes, and divided according to the intracanal dressing used: triple antibiotic paste - TAP, double antibiotic paste - DAP, calcium hydroxide associated with 2% chlorhexidine gel, calcium hydroxide associated with saline solution, and Bio-C Temp. As control, no dressing was performed. The intracanal dressings remained in the simulated root canal for 21 days. Luminosity (ΔL) and color difference (ΔEab and ΔE00) were evaluated using long-term (1 year) spectrophotometric analysis. The results were analyzed using the ANOVA test with Tukey's post hoc with a significance of 5%. RESULTS TAP showed the highest values of ΔEab and ΔE00 and lowest values of ΔL (p < .05). Bio-C Temp showed higher ΔEab than the other groups from 6 months (p < .05), higher ΔE00 and lower ΔL after one year (p < .05). CONCLUSIONS Bio-C Temp induced noticeable coronary discoloration after the one-year analysis.

Abstract
A steadily increasing public demand for whiter teeth has resulted in the development of new oral care products for home use. Hydroxyapatite (HAP) is a new ingredient to whiten teeth. This systematic review focuses on the evidence of whether HAP can effectively whiten teeth. A systematic search using the PICO approach and PRISMA guidelines was conducted using PubMed, Scopus, Web of Science, SciFinder, and Google Scholar as databases. All study designs (in vitro, in vivo) and publications in foreign language studies were included. Of the 279 study titles that the searches produced, 17 studies met the inclusion criteria. A new "Quality Assessment Tool For In Vitro Studies" (the QUIN Tool) was used to determine the risk of bias of the 13 studies conducted in vitro. Moreover, 12 out of 13 studies had a low risk of bias. The in vivo studies were assigned Cochrane-based GRADE scores. The results in vitro and in vivo were consistent in the direction of showing a statistically significant whitening of enamel. The evidence from in vitro studies is rated overall as having a low risk of bias. The evidence from in vivo clinical trials is supported by modest clinical evidence based on six preliminary clinical trials. It can be concluded that the regular use of hydroxyapatite-containing oral care products effectively whitens teeth, but more clinical trials are required to support the preliminary in vivo evidence.

Abstract
Background: Certain drugs can cause intrinsic or extrinsic tooth discoloration, which is not only a clinical issue but also an esthetic problem. However, limited investigations have focused on drug-induced tooth discoloration. The present work aimed to determine the drugs causing tooth discoloration and to estimate their risks of causing tooth discoloration. Methods: An observational, retrospective, and pharmacovigilance analysis was conducted, in which we extracted adverse event (AE) reports involving tooth discoloration by using the data of the US Food and Drug Administration's Adverse Event Reporting System (FAERS) from the first quarter (Q1) of 2004 to the third quarter (Q3) of 2021. Disproportionality analyses were performed to examine risk signals for tooth discoloration and determine the drugs inducing tooth discoloration. Results: Based on predefined inclusion criteria, 1188 AE reports involving 302 suspected drugs were identified. After data mining, 25 drugs generated positive risk signals for tooth discoloration, of which 10 were anti-infectives for systemic use. The top reported drug was tetracycline (n = 106), followed by salmeterol and fluticasone (n = 68), amoxicillin (n = 60), chlorhexidine (n = 54), and nicotine (n = 52). Cetylpyridinium (PRR = 472.2, ROR = 502.5), tetracycline (PRR = 220.4, ROR = 277), stannous fluoride (PRR = 254.3, ROR = 262.8), hydrogen peroxide (PRR = 240.0, ROR = 247.6), and chlorhexidine (PRR = 107.0, ROR = 108.4) showed stronger associations with tooth discoloration than the remaining drugs. Of 625 AE reports involving 25 drugs with positive risk signals, tooth discoloration was mostly reported in patients aged 45-64 (n = 110) and ≤18 (n = 95), and 29.4% (192/652) of the reports recorded serious outcomes. Conclusion: This study revealed that certain drugs are significantly associated with tooth discoloration. Caution should be exercised when using these drugs, especially during pregnancy and early childhood.

Abstract
This study aims to evaluate the anti-caries effect of a mouthwash containing Lespedeza cuneata extract by confirming its effect on acid-producing capacity and bacteria causing dental caries in the oral cavity. For the same oral environments of 95 subjects who agreed to participate in this study, scaling was performed one week before the experiment. The final number of subjects included in the analysis was 82, excluding those who dropped out during the study period. A randomized placebo-controlled trial was conducted by dividing the subjects into the Lespedeza cuneata extract gargle group (n = 42) and the saline gargle group (n = 40). Participants in each group gargled once every day before going to bed for 5 days, and data were collected by measuring 3 times: before gargling (Baseline), immediately after gargling (Treatment), and 5 days after gargling (After 5 Days). Two trained dental hygienists confirmed the dental caries activity through the Cariview test under the guidance of a dentist. Microbiological analysis was performed to evaluate the changes in bacteria causing dental caries. By confirming the anti-caries effect in the oral environment according to the application of Lespedeza cuneata extract gargle, dental caries activity was found to be significantly lower from Treatment to After 5 Days (p < 0.05). Dental caries-causing bacteria in the upper and lower jaws were also significantly reduced (p < 0.05). These results confirm that Lespedeza cuneata extract is a natural substance with an anti-caries effect. Gargling with a mouthwash containing Lespedeza cuneata extract is useful in preventing dental caries and inhibiting its progression. The same mouthwash can also be used as an effective formulation for maintaining and promoting oral health.

Abstract
Tetracyclines are a broad-spectrum class of antibiotics that have unclear actions with potentially lasting effects on bone metabolism. Initially isolated from Streptomyces, tetracycline proved to be an effective treatment for Gram +/- infections. The emergence of resistant bacterial strains commanded the development of later generation agents, including minocycline, doxycycline, tigecycline, sarecycline, omadacycline, and eravacycline. In 1957, it was realized that tetracyclines act as bone fluorochrome labels due to their high affinity for the bone mineral matrix. Over the course of the next decade, researchers discerned that these compounds are retained in the bone matrix at high levels after the termination of antibiotic therapy. Studies during this period provided evidence that tetracyclines could disrupt prenatal and early postnatal skeletal development. Currently, tetracyclines are most commonly prescribed as a long-term systemic therapy for the treatment of acne in healthy adolescents and young adults. Surprisingly, the impact of tetracyclines on physiologic bone modeling/remodeling is largely unknown. This article provides an overview of the pharmacology of tetracycline drugs, summarizes current knowledge about the impact of these agents on skeletal development and homeostasis, and reviews prior work targeting tetracyclines' effects on bone cell physiology. The need for future research to elucidate unclear effects of tetracyclines on the skeleton is addressed, including drug retention/release mechanisms from the bone matrix, signaling mechanisms at bone cells, the impact of newer third generation tetracycline antibiotics, and the role of the gut-bone axis.

Abstract
In this study, we aimed to explore the trends among dentists in the Dominican Republic of providing antibiotic prescriptions to pregnant/breastfeeding dental patients. A survey was conducted among 98 dentists, using a self-administered questionnaire, about their knowledge and attitudes regarding antibiotic usage in pregnant/lactating women and the translation of these into practice. The majority of the survey population were female dentists (63.3%) aged 45–54 years. A chi-square test showed statistically significant differences in the knowledge sources between older and younger dentists, with a minority having chosen scientific literature as a source (p-value of 0.04). There were statistically significant associations between gender and certain attitudes and practice-based questions, with p-values of 0.04 and 0.01, respectively. The Spearman’s correlation test showed a statistically significant correlation between knowledge and attitude (p-value 0.001), whereas no correlation was found with practice (p-value 0.23). A multiple response analysis showed that the majority of the respondents chose the second and third trimester for antibiotic prescriptions for acute conditions such as cellulitis, periodontal abscess, and pericoronitis. Most dentists had sufficient knowledge about antibiotic usage in pregnant/lactating women, but it did not translate into practice, and a certain proportion of the participants followed incongruent drug prescription. These findings can be used to focus on judicious antibiotic usage by dentists in the Dominican Republic.

Abstract
Introduction Developmental anomalies are malformation which arises due to the disturbances during the development of the organs. Although there have been many studies that have described the prevalence of these anomalies in the oral cavity, none have specified the prevalence of clinically manifested anomalies and their distribution between gender. Materials and methods In this study, 500 patients aged 18 to 50 years were screened for clinically manifested developmental anomalies. These were then divided based on age, sex, and jaws, which were then analyzed using a chi-square test and tabulated. Results We detected anomalies in 12.2% of the study population. Supernumerary teeth were the most prevalent anomaly detected (4.25%). The frequency of developmental anomalies was higher in men (57.1%). Conclusions Supernumerary teeth were the most widely recognized anomaly. Other anomalies identified were related to the shape and size of teeth. These anomalies can lead to severe orofacial problems. Therefore, proper care of these anomalies should be taken.

Abstract
We investigated the inhibitory effect of antibacterial agents mixed with experimental fluoride varnish (EFV) on Streptococcus mutans. The antibacterial agents used were (1 and 10) mM of xanthorrhizol, bakuchiol, bavachalcone, isobavachromene, and bavachromene. Agar diffusion tests were performed on S. mutans (1.1×1010 CFU/mL), using antibacterial agents without and with EFV. Bavachalcone showed the highest inhibition zone without and with EFV at both (1 and 10) mM (p<0.05). All EFV with antibacterial agents showed greater inhibition and semi-inhibition zones than EFV alone (p<0.05). The cell viability of each antibacterial agent was not significantly different from the vehicle controls (p>0.05), except xanthorrhizol and bakuchiol at 1 mM. All antibacterial agents were effective, while antibacterial agents with EFV co-formulations were more effective than EFV alone. Bavachalcone was the most effective agent against S. mutans, indicating its potential usefulness with fluoride varnish in preventing dental caries.

Abstract
BACKGROUND Dental caries is the most common and one of the prevalent diseases in the world. Streptococcus mutans is one of the major oral pathogens that cause dental caries by forming a biofilm on dental tissues, degrading dental enamel and consequent cavitation in the tissue. In vitro selection of drug targets is a laborious and expensive process and therefore, computational methods are preferable for target identification at the initial stage. OBJECTIVE The present research aims to find new drug targets in S. mutans by using subtractive proteomics analysis, which implements various bioinformatics tools and databases. METHODS The proteome of S. mutans UA159 was mined for novel drug targets using computational tools and databases such as: CD-HIT, BLASTP, DEG, KAAS and CELL2GO. RESULTS Out of 1953 proteins of S. mutans UA159, proteins that are redundant, homologous to human and non-essential to the pathogen were eliminated. Around 178 proteins already available in drug target repositories were also eliminated. Possible functions and subcellular localization of 32 uncharacterized proteins were predicted. Substantially, 13 proteins were identified as novel drug targets in S. mutans UA159 that can be targeted by various drugs against dental caries. CONCLUSION This study will effectuate the development of novel therapeutic agents against dental caries and other Streptococcal infections.

Abstract
Pronounced white color alterations due to structural anomalies of the enamel are often insufficiently masked by bleaching techniques or resin infiltration procedures alone. This frequently leads to the choice of more invasive prosthetic restorations in order to correct tooth color and form. This article describes a minimally invasive treatment option for esthetic and functional rehabilitation in the case of a 13-year-old female patient with suspected severe fluorosis and misalignment of the anterior teeth. The restorations were performed using underlying resin infiltration to homogenize the tooth shade. In a second step, direct composite veneers were applied on top to attain a natural tooth color and adjust tooth alignment and form. By joining the two minimally and noninvasive techniques, this treatment option combines the directive for preservation of hard tooth structure while treating adolescents with the benefits of easy adaptation and repair when the occlusion is still in adjustment.

Abstract
The purpose of this study was to determine the anti-inflammatory and in vitro bone formation effects of Garcinia mangostana L. (mangosteen) and propolis extracts. Immortalized human gingival fibroblasts (hTERT-hNOF) cells were treated with Porphyromonas gingivalis KCOM 2804 lipopolysaccharide followed by treatment with mangosteen and propolis extract alone or in combination. Expression levels of inflammatory cytokines were evaluated by enzyme-linked immunosorbent assay. Effect of mangosteen and/or propolis extracts on mineralization of MG-63 cells was evaluated by alkaline phosphatase activity and alizarin red S staining. Group mangosteen extract complex 1:34 (1 µg/ml mangosteen extract and 34 µg/ml propolis extract) significantly reduced expression levels of IL-6, IL-8, and PGE2. It had higher than other groups in vitro bone formation effect on MG63 cells. These results suggest that mangosteen and propolis extract complex could be used in the prevention and treatment of periodontal disease.

Abstract
BACKGROUND Tooth discoloration may be caused by intrinsic or extrinsic stains or a combination of both. There are 2 major approaches to removing the stains, including the chemical mechanism using peroxides for tooth bleaching and the mechanical mechanism using abrasives in prophylactic pastes and dentifrices to remove stains, resulting in a whitening effect. Attempts have also been made to add a low concentration of peroxides to dentifrices to enhance their abrasive cleaning to remove tooth stains. TYPES OF STUDIES REVIEWED This article provides a review of both in vitro and clinical studies on stain removal and whitening effect of dentifrices containing sodium bicarbonate (baking soda). In recent years, whitening dentifrices have become popular because of little additional effort for use, ease of availability, low cost, and accumulated evidence of clinical efficacy and safety in the literature. Advances in research and technology have led to innovative formulations of dentifrices using baking soda as the sole abrasive or a component of an abrasive system. Baking soda is biologically compatible with acid-buffering capacities, antibacterial at high concentrations, and has a relatively lower abrasivity. CONCLUSIONS The evidence available in the literature indicates that baking soda-based dentifrices are effective and safe for tooth stain removal and consequently whitening. A number of clinical studies have also shown that baking soda-based dentifrices are more effective in stain removal and whitening than some non-baking soda-containing dentifrices with a higher abrasivity. So far, research efforts have mainly focused on stain removal and tooth-whitening efficacy and clinical safety of baking soda dentifrices used with manual toothbrushes, with only a few studies investigating their effects using powered toothbrushes, for which further research is encouraged. PRACTICAL IMPLICATIONS As part of a daily oral hygiene practice, baking soda-based dentifrice is a desirable, alternative or additional measure for tooth stain removal and whitening.

Abstract
The novelty of this study consists of the formulation and characterization of three experimental bleaching gels with hydroxylapatite oxides and fluorine (G28®, G29®, G30®) based on natural fruit extracts compared to the commercial Opalescence 15% (GC, Ultradent, South Jordan, UT, USA). Studies have been conducted on the effect that the experimental bleaching gels have on the color and morphology of different restorative materials (Nanofill®-Schulzer, P.L. Superior Dental Materials GmbH, Hamburg, Germany, and experimental nanocomposites (P11®, P31®, P61®)), immersed in coffee and artificial saliva (for 10 days and 30 days). The study also includes a cytotoxicity test on the gels and nanocomposites after bleaching, with ISO 109993-5 protocols on human dental follicle stem cells. UV-VIS spectroscopy, computerized measurement, and fluorescence spectrometry were used in order to observe the color changes, while the microstructure of the surface was investigated by Scanning Electron Microscopy (SEM). All of the samples immersed in coffee showed the highest color shift in comparison to the baseline. The color difference ΔE values obtained using the two methods (UV-Vis, computerized based on digital images) both after coloring and bleaching, respectively, were different for all four types of nanocomposites stored in the coffee, while no difference was observed in those stored in artificial saliva. The studied experimental gels and nanocomposites had a low cytotoxic effect on cell cultures after bleaching.

Has doxycycline, in combination with anti-malarial drugs, a role to play in intermittent preventive treatment of Plasmodium falciparum malaria infection in pregnant women in Africa?

Abstract
According to the World Health Organization (WHO), Plasmodium falciparum malaria during pregnancy is responsible for deleterious consequences for the mother and her child. The administration of intermittent preventive treatment (IPTp) with sulfadoxine–pyrimethamine (SP) at each antenatal care visit as early as 13 weeks of gestation until the time of delivery is a strategy that is currently recommended by WHO for the prevention of malaria in pregnancy. However, the emergence and the spread of the resistance to SP in Africa raise the question of the short-term effectiveness of the strategy. Dihydroartemisinin–piperaquine 120 mg/960 mg once a day for 3 consecutive days administered at least three times during the pregnancy might be an option for IPTp. The combination of 200 mg of doxycycline once a day for 3 consecutive days seems to be a good option to retard the emergence and the spread of resistance to artemisinin-based combination therapy (ACT) in Africa and improve the effectiveness of ACT in term of preterm births, neonatal morbidity and mortality. Contrary to preconceived ideas, scientific and medical data suggest that the risk of congenital malformations in the fetus or of tooth staining in infants whose mothers take doxycycline and hepatotoxicity during pregnancy is very low or non-existent. Additionally, the use of doxycycline during the first and second trimesters leads to an increase in gestational age at delivery, a decrease in the number of preterm births and a reduction in neonatal morbidity and mortality due to the beneficial antimicrobial activity of doxycycline against other infections during pregnancy. Furthermore, doxycycline has anti-malarial properties and is already recommended as prophylaxis for travellers and for treatment of falciparum malaria in combination with other anti-malarial drugs.

Abstract
Background Adverse reaction to medication is common and may have a variety of clinical manifestations in the oral cavity. The present review paper aimed to describe adverse drug reactions (ADRs) which might be encountered by dental practitioners in every discipline. Methods In this narrative review article, the specialized databases such as PubMed, PubMed Central, MEDLINE, EBSCO, Science Direct, Scopus, and reference books from the years 2000-2016 were used to find relevant documents by using MeSH terms: Adverse Drug Reaction, Drug induced, Medication Related, Mouth, Oral Manifestation, Tooth, Hard Tissue, Soft Tissue. Results The data were categorized in 4 groups as follows: saliva and salivary glands involvement, soft tissue (mucosal) involvement, hard tissue involvement, and non specific conditions (taste disorders, halitosis, neuropathies, movement disturbances, and infection). Most articles were about the adverse effect of drugs on the function of salivary glands, which often cause a decrease in saliva secretion. Other reactions were less common; meanwhile, the side effect of bisphosphonate was increasing in the alveolar bone, because of its unlimited prescription. Conclusion Oral health care providers should be familiar with such events, as they will be confronted with them in their practice.

Abstract
Anti-malarial drug resistance to chloroquine and sulfadoxine–pyrimethamine has spread from Southeast Asia to Africa. Furthermore, the recent emergence of resistance to artemisinin-based combination therapy (ACT) in Southeast Asia highlights the need to identify new anti-malarial drugs. Doxycycline is recommended for malaria chemoprophylaxis for travel in endemic areas, or in combination with the use of quinine for malaria treatment when ACT is unavailable or when the treatment of severe malaria with artesunate fails. However, doxycycline is not used in young children under 8 years of age due to its contraindication due to the risk of yellow tooth discolouration and dental enamel hypoplasia. Doxycycline was developed after tetracycline and was labelled with the same side-effects as the earlier tetracyclines. However, recent studies report little or no effects of doxycycline on tooth staining or dental enamel hypoplasia in children under 8 years of age. In the United States, the Centers for Disease Control and Prevention have recommended the use of doxycycline for the treatment of acute and chronic Q fever and tick-borne rickettsial diseases in young children. It is time to rehabilitate doxycycline and to recommend it for malaria treatment in children under 8 years of age.

Abstract
Cystic fibrosis (CF) is a chronic disorder characterized by acute pulmonary exacerbations that comprise increased cough, chest congestion, increased mucus production, shortness of breath, weight loss, and fatigue. Typically, severe episodes are treated in the inpatient setting and include intravenous antimicrobials, airway clearance therapy, and nutritional support. Children with less-severe findings can often be managed as outpatients with oral antimicrobials and increased airway clearance therapy at home without visiting the specialty CF center to begin treatment. Selection of specific antimicrobial agents is dependent on pathogens found in surveillance culture, activity of an agent in patients with CF, and the unique physiology of these patients. In this pediatric review, we present our practice for defining acute pulmonary exacerbation, deciding treatment location, initiating treatment either in-person or remotely, determining the frequency of airway clearance, selecting antimicrobial therapy, recommending timing for follow-up visit, and recognizing and managing treatment failures.

Abstract
INTRODUCTION Sucrose is added as sweetening agent in liquid oral medication (LOM) to mask the acrid taste of medicines which may be potentially cariogenic. Many children under long term LOM therapy for treatment of epilepsy may be susceptible to dental caries. AIM To assess and compare dental caries experience in children under long term liquid oral medication with those not under such medication among 2-12 years old children suffering from epilepsy. MATERIALS AND METHODS A cross-sectional study was undertaken on a total of 84 children aged 2-12 years, who were suffering from epilepsy receiving liquid oral medication for more than 3 months were selected (study group) and for comparison 106 children of similar age group and disease but on other forms of medication were included as control group. Dental caries was assessed using DMFT/DMFS (Decayed, Missing, Fillled Teeth / Surfaces), dmft/dft and dmfs/dfs indices. One-way ANOVA and t-test were used with p-value fixed at 0.05. Univariate logistic regression was applied. RESULTS Children on LOM were at increased risk of dental caries than those with other forms of medications (OR: 2.55, 95% CI (2.37-4.15) p=0.000, HS). Caries prevalence was high in the study group (76.1%) when compared to control group (55.6%). CONCLUSION Long term use of liquid medicines containing sucrose is a risk factor for dental caries among children with epilepsy.

Abstract
Introduction: Doxycycline is highly effective, inexpensive with a broad therapeutic spectrum and exceptional bioavailability. However these benefits have been overshadowed by its classification alongside the tetracyclines – class D drugs, contraindicated in pregnancy and in children under 8 years of age. Doxycycline-treatable diseases are emerging as leading causes of undifferentiated febrile illness in Southeast Asia. For example scrub typhus and murine typhus have an unusually severe impact on pregnancy outcomes, and current mortality rates for scrub typhus reach 12-13% in India and Thailand. The emerging evidence for these important doxycycline-treatable diseases prompted us to revisit doxycycline usage in pregnancy and childhood. Areas Covered: A systematic review of the available literature on doxycycline use in pregnant women and children revealed a safety profile of doxycycline that differed significantly from that of tetracycline; no correlation between the use of doxycycline and teratogenic effects during pregnancy or dental staining in children was found. Expert Opinion: The change of the US FDA pregnancy classification scheme to an evidence-based approach will enable adequate evaluation of doxycycline in common tropical illnesses and in vulnerable populations in clinical treatment trials, dosage-optimization pharmacokinetic studies and for the empirical treatment of undifferentiated febrile illnesses, especially in pregnant women and children.

Abstract
Minocycline is widely used as a first-line agent for papulopustular acne, and has previously been reported as causing stains on teeth that are still forming. This article reports a case of staining to only the crowns of unerupted third molars in a girl prescribed minocycline at age 16 for papulopustular acne. We review the literature in the area of minocycline teeth staining, consider the role of minocycline as a first-line agent for papulopustular acne, and outline strategies on the prevention of minocycline teeth staining. The case highlights current deficiencies in the disclosure information for minocycline, and provides information that is relevant to practitioners who may prescribe this drug.

Abstract
BACKGROUND The appropriate choice of antibiotics against Mycoplasma pneumoniae infection has become difficult, as the prevalence of macrolide-resistant M. pneumoniae has increased. METHODS Throat swab specimens were collected from children with clinically suspected M. pneumoniae infection while visiting an outpatient clinic. Cultures for M. pneumoniae were done, and all isolates were sequenced for the presence of a mutation in 23S rRNA. RESULTS Of the 80 specimens collected between February 2012 and March 2013, 27 (34%) were positive for M. pneumoniae on culture. Macrolide-resistant mutation was detected in 24 isolates (89%): 23 isolates had an A2063G transition, and one had a C2617G mutation. Both the median age and the prevalence of pneumonia were significantly higher in M. pneumoniae-positive than in M. pneumoniae-negative children (median, 7 years vs 4 years; 88.9% vs 60.4%, respectively). The percentage of serum samples with particle agglutination titer ≥ 1:160 was 69.6% in M. pneumoniae-positive cases and 17.6% in M. pneumoniae-negative cases when the serum was collected ≥ 4 days after the onset of fever. Defervescence within 72 h after the initiation of macrolides never occurred in M. pneumoniae-positive children and also did not occur in 54% of M. pneumoniae-negative children. Switching to either minocycline or tosufloxacin resulted in fever resolution within 48 h in M. pneumoniae-positive children. CONCLUSIONS The described clinical and laboratory characteristics of M. pneumoniae infection may be useful in guiding appropriate treatment in an outpatient clinic.

Abstract
The anti-inflammatory, antioxidant, and antimicrobial properties of artemisinin derived from water, methanol, ethanol, or acetone extracts of Artemisia annua L. were evaluated. All 4 artemisinin-containing extracts had anti-inflammatory effects. Of these, the acetone extract had the greatest inhibitory effect on lipopolysaccharide-induced nitric oxide (NO), prostaglandin E2 (PGE2), and proinflammatory cytokine (IL-1β , IL-6, and IL-10) production. Antioxidant activity evaluations revealed that the ethanol extract had the highest free radical scavenging activity, (91.0±3.2%), similar to α-tocopherol (99.9%). The extracts had antimicrobial activity against the periodontopathic microorganisms Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum subsp. animalis, Fusobacterium nucleatum subsp. polymorphum, and Prevotella intermedia. This study shows that Artemisia annua L. extracts contain anti-inflammatory, antioxidant, and antimicrobial substances and should be considered for use in pharmaceutical products for the treatment of dental diseases.

Abstract
BACKGROUND The effects of maternal use of medicines during pregnancy on tooth development has scarcely been studied; only negative effects of tetracycline on tooth germs are known (irreversible tooth discoloration and enamel hypoplasia). OBJECTIVE The aim of this study was to investigate whether antibacterials and anti-allergic and anti-asthma medicines, being the most frequently used medicines during pregnancy, are associated with deciduous molar hypomineralisation (DMH) and, if so, which specific medicines. MATERIALS AND METHODS To clarify this possible association, the participants of the Generation R Study, a population-based prospective cohort study from fetal life until young adulthood, were studied. Data on medicine use during pregnancy were retrieved from pharmacies. Clinical photographs of the second primary molars, which were scored for DMH, were taken with an intra-oral camera in 6,690 children (mean age 6.2 years, standard deviation [SD] ± 0.53; 49.9 % girls). RESULTS During pregnancy, 20.3 % of the mothers used antibacterials, 12.3 % anti-asthma medicines and 5.4 % anti-allergic medicines. The prevalence of DMH was 9.0 % in the study group. There was no association between the use of anti-asthma medicines, anti-allergic medicines (odds ratio [OR]: 0.97 [95 % CI 0.61-1.54]; OR: 1.04 [0.54-2.03]) or antibacterials (OR: 0.73 [0.49-1.09]) during pregnancy and DMH (all p-values >0.05). The study had sufficient power (80 %) to detect significant associations. CONCLUSION Maternal use of antibacterials, anti-allergic medicines or anti-asthma medicines during pregnancy is not associated with the development of DMH in the offspring.

Abstract
UNLABELLED The single discoloured tooth is commonly encountered in general practice. This is the first of two articles covering the broad range of management options for the single discoloured tooth. This first part outlines the common causes of discoloration and possible methods of prevention. Minimally invasive techniques are covered. Clinical procedures are outlined and clinical cases used to demonstrate outcomes that can be achieved. CLINICAL RELEVANCE The single discoloured tooth is a commonly encountered clinical problem in general dental practice. A wide variety of management options exist and any one in particular may be most appropriate given the clinical scenario. It is therefore essential that general dental practitioners are familiar with the range of options that exist, as well as their indications, and consider adopting minimally invasive techniques in the first instance before moving to more invasive therapies.

Abstract
BACKGROUND Increasing resistance of oral pathogens to conventional antibacterial agents has resulted to find alternative therapies to overcome resistance development problems; hence this in vitro study was carried out to investigate the efficacy of photoelimination of Streptococcus mutans with two methods of photodynamic and photothermal therapy. METHODS Standard Suspensions of S. mutans were treated in two groups of photodynamic therapy with Toluidine blue O and Rhadachlorin(®) and photothermal therapy by EmunDo(®) and their individual light sources, then Bacterial suspension from each treatment was subcultured on the surface of Mueller-Hinton agar plates and bacterial growth was assessed. The results were analyzed by analysis of variance and Tukey test (p<0.05). RESULTS After treatments significant reduction of S. mutans viability in planktonic culture was observed in both groups of photodynamic and photothermal therapy with no priority. CONCLUSION Photoelimination can be a novel modality in the eradication of S. mutans colonies in near future.

Abstract
BACKGROUND AND OVERVIEW Despite advances in the study of birth defects related to drug exposures during pregnancy, medication use during pregnancy still causes anxiety and misunderstanding among both members of the public and health care professionals. This may result in a woman's unknowingly taking a medication that may harm the fetus or cause a birth defect or discontinuing medications necessary for treating chronic conditions. Using medications while breast-feeding also represents a challenge for patients and prescribers. Many mothers are told they must stop breast-feeding or "pump and discard" their breast milk if they are taking certain medications; however, in many cases, this advice-based on what may be limited education on the part of the health care provider about breast-feeding and medication use-may be incorrect. The authors review the current evidence regarding drugs that may be safe for pregnant or breast-feeding patients and medications that such patients should avoid. CONCLUSIONS When considering prescribing in pregnancy, the dentist must weigh the risk to the fetus versus the benefit to the mother, and the appropriate conclusion should reflect current evidence. In some cases medication dosing should be avoided or altered; however, there are times when it is unnecessary to stop the use of medications. Breast-feeding also represents a clinical challenge, the risks and benefits of which need to be understood by both the patient and practitioner before any medication is administered. PRACTICE IMPLICATIONS Dentists should be familiar with the risks and benefits for pregnant or breast-feeding patients posed by five types of medications: analgesics and anti-inflammatories, antibiotics, local anesthetics, sedatives and emergency medications.

Abstract
Salvadora persica sticks are used for chewing and oral-hygiene measures worldwide. The growth inhibition and anti-biofilm effects of various extracts on cariogenic Streptococcus mutans isolates were evaluated. Biofilm inhibition, gas chromatography-mass spectrometry (GC-MS) analyses for phytochemicals and their possible mode of interaction with biofilm response regulators were revealed using LigandFit docking protocols. All S. persica extracts showed considerable inhibitory activity and the cariogenic S. mutans showed varied susceptibility when compared with controls. The percentage reduction in biofilm inhibition obtained for methanol, ethanol, chloroform, acetone, and aqueous extracts were 87.92%, 85.75%, 72.44%, 61.66% and 58.68%, respectively. GC-MS analyses revealed >28 compounds, of which benzyl (6Z,9Z,12Z)-6,9,12-octadecatrienoate, 3-benzyloxy-1-nitro-butan-2-ol and 1,3-cyclohexane dicarbohydrazide interacted efficiently with the bacterial communication quorum-sensing (QS) regulators Streptococcus OmpP and Staphylococcus Lux proteins. The bioactive, dual-function, anti-biofilm agents in S. persica not only inhibit growth, but also control the colonization and accumulation of caries-causing S. mutans.

Abstract
Minocycline can rescue the dendritic spine and synaptic structural abnormalities in the fragile X knock-out mouse. This is a review and preliminary survey to document side effects and potential outcome measures for minocycline use in the treatment of individuals with fragile X syndrome. We surveyed 50 patients with fragile X syndrome who received minocycline for at least 2 weeks and found that the most common reported side effect is gastrointestinal difficulty, including loss of appetite. The families reported an improvement in language and behavioral areas. Outcome measures in the design of future randomized clinical trials should include both behavioral and language measures. As with any other treatments, we emphasize that randomized clinical trials are needed to determine the efficacy of minocycline in fragile X syndrome.

Abstract
Growing interest in the treatment and prevention of Molar/Incisor Hypomineralization (MIH) warrants investigation into the protein composition of hypomineralized enamel. Hypothesizing abnormality akin to amelogenesis imperfecta, we profiled proteins in hypomineralized enamel from human permanent first molars using a biochemical approach. Hypomineralized enamel was found to have from 3- to 15-fold higher protein content than normal, but a near-normal level of residual amelogenins. This distinguished MIH from hypomaturation defects with high residual amelogenins (amelogenesis imperfecta, fluorosis) and so typified it as a hypocalcification defect. Second, hypomineralized enamel was found to have accumulated various proteins from oral fluid and blood, with differential incorporation depending on integrity of the enamel surface. Pathogenically, these results point to a pre-eruptive disturbance of mineralization involving albumin and, in cases with post-eruptive breakdown, subsequent protein adsorption on the exposed hydroxyapatite matrix. These insights into the pathogenesis and properties of hypomineralized enamel hold significance for prevention and treatment of MIH.

Abstract
Buccal cells are an important source of DNA in epidemiological studies, but little is known about factors that influence amount and purity of DNA. We assessed these factors in a self-administered buccal cell collection procedure, obtained with three cotton swabs. In 2,451 patients DNA yield and in 1,033 patients DNA purity was assessed. Total DNA yield ranged from 0.08 to 1078.0 μg (median 54.3 μg; mean 82.2 μg ± SD 92.6). The median UV 260:280 ratio, was 1.95. Samples from men yielded significantly more DNA (median 58.7 μg) than those from women (median 44.2 μg). Diuretic drug users had significantly lower purity (median 1.92) compared to other antihypertensive drug users (1.95). One technician obtained significantly lower DNA yields. Older age was associated with lower DNA purity. In conclusion, DNA yield from buccal swabs was higher in men and DNA purity was associated with age and the use of diuretics.
