Abstract
OBJECTIVE Sirtuin3 (SIRT3) is a NAD+-dependent major mitochondrial deacetylase. In this study, we aimed to investigate SIRT3 levels and their target enzyme activities, including glutamate dehydrogenase (GDH), succinate dehydrogenase (SDH), and manganese superoxide dismutase (MnSOD), also to determine the antioxidant capacity and oxidative stress in tissue, mitochondria and serum samples in ovarian endometrioma patients. METHODS We collected serum and endometrioma tissue samples from 30 patients. In the control group, we collected serum and eutopic endometrial tissue samples from 26 women without endometriosis. RESULTS SIRT3 levels were significantly decreased in endometrioma tissue samples compared to the control group. There was no statistically significant difference in SIRT3 levels between patient and control serum samples. Furthermore, there was a decrease in GDH and SDH enzyme activities in both endometrioma tissue homogenate and mitochondria. MnSOD activity was decreased in tissue homogenate but increased in mitochondria and there was no difference in serum. While total SOD activity was decreased, CuZnSOD activity was increased in both tissue and serum samples. Besides these, total antioxidant capacity and advanced oxidation protein products (AOPP) levels were decreased in endometrioma tissue and mitochondria, but there was no difference in serum. CONCLUSIONS Our results suggested that decreased levels of SIRT3 in endometrioma may be an important factor in the weakening of mitochondrial energy metabolism and antioxidant defense in endometriosis. We think that SIRT3 deficiency may be an important factor underlying the pathogenesis of endometriosis. More detailed studies are needed to reveal the relationship between SIRT3 and metabolism and oxidative stress in ovarian endometrioma.

Abstract
Endometriosis is a complex disease characterized by inflammation and the growth of endometrial- like glands and stroma outside the uterine cavity. The pathophysiology of endometriosis is not entirely understood, however, with a prevalence of ~10% of women in their reproductive years, the disease symptoms significantly affect the quality of life of millions of women globally. Metabolomic studies have previously identified specific metabolites that could be a signature of endometriosis. This approach could potentially be used as a non-invasive tool for early diagnosis and provide a better understanding of endometriosis pathophysiology. This review aims to provide insight as to how endometriosis affects the metabolome by reviewing different studies that have used this approach to design follow-up studies. The search query included the term 'endometriosis' in combination with 'metabolomics', 'lipidomics', or 'sphingolipidomics' published between 2012 and 2020. We included studies in humans and animal models. Most studies reported differences in the metabolome of subjects with endometriosis in comparison to healthy controls and used samples taken from serum, endometrial tissue, follicular fluid, urine, peritoneal fluid, or endometrial fluid. Statistically significant metabolites contributed to group separation between patients and healthy controls. Reported metabolites included amino acids, lipids, organic acids, and other organic compounds. Differences in methods, analytical techniques, and the presence of confounding factors can interfere with results and interpretation of data. Metabolomics seems to be a promising tool for identifying significant metabolites in patients with endometriosis. Nonetheless, more investigation is needed in order to understand the significance of the study results.
Lay summary
Endometriosis is a chronic disease affecting the quality of life in one out of every ten women during their reproductive years, causing pain and infertility. It is characterized by inflammation and growth of tissue like the endometrium (uterus lining) outside the uterine cavity. Studies have searched for a predictor of endometriosis-associated changes by observing small molecules necessary for metabolism on a large scale (metabolomics). Metabolomics could serve to resolve one of the biggest challenges that patients with endometriosis face: a delay in diagnosis. In this review, the authors summarize identified potential biomarkers from various bodily fluids and tissues that are characteristic of metabolic processes observed in endometriosis. Biomarkers include cell growth, cell survival, high energy demand, oxidative stress, and fatty acid levels. A metabolomics approach offers promise as a non-invasive tool to identify significant metabolite changes in patients with endometriosis, potentially leading to earlier diagnoses and new opportunities for back-translational strategies.

Abstract
Endometriosis is a chronic inflammatory condition, which is distinguished by the presence of the endometrial-like glands and stroma outside the uterine cavity. Pain and infertility are the most commonly expressed symptoms, occurring in 60% and 40% of cases, respectively. Women with endometriosis, especially those with pelvic pain, also have a greater vulnerability to several psychiatric disorders. There is, in particular, a tendency to contract affective or anxiety disorders as well as panic-agoraphobic and substance use disorders. Endometriosis with pelvic pain, infertility and psychic vulnerability usually leads to disability and a markedly lower quality of life for women of reproductive age. Thus, the burden of endometriosis is not limited to the symptoms and dysfunctions of the disease; it extends to the social, working and emotional spheres, leading to a severe impairment of global functioning. An analysis of scientific literature revealed a close relationship between specific temperamental traits, the expression of several psychiatric symptoms, chronicity of pain, risk of substance use and lower probability of a positive outcome. Endometriosis symptoms and the impact of related psychological consequences, increased vulnerability and the possible onset of psychiatric symptoms may influence coping strategies and weaken resilience, so triggering a vicious cycle leading to a marked deterioration in the quality of life. A multidisciplinary approach consisting of a medical team composed of gynecologists, psychologists, psychiatrists, experts in Dual Disorder, algologists and sexologists, would guarantee the setting of a target and taking the best decision on a personalized treatment plan. That approach would allow the prompt detection of any psychopathological symptoms and improve the endometriosis-related physical symptoms, bringing a healthier quality of life and a greater likelihood of a positive outcome.

Abstract
Infertility is a complex multifactorial disease that affects up to 10% of couples across the world. However, many mechanisms of infertility remain unclear due to the lack of studies based on systematic knowledge, leading to ineffective treatment and/or transmission of genetic defects to offspring. Here, we developed an infertility disease database to provide a comprehensive resource featuring various factors involved in infertility. Features in the current IDDB version were manually curated as follows: (i) a total of 307 infertility-associated genes in human and 1348 genes associated with reproductive disorder in 9 model organisms; (ii) a total of 202 chromosomal abnormalities leading to human infertility, including aneuploidies and structural variants; and (iii) a total of 2078 pathogenic variants from infertility patients’ samples across 60 different diseases causing infertility. Additionally, the characteristics of clinically diagnosed infertility patients (i.e. causative variants, laboratory indexes and clinical manifestations) were collected. To the best of our knowledge, the IDDB is the first infertility database serving as a systematic resource for biologists to decipher infertility mechanisms and for clinicians to achieve better diagnosis/treatment of patients from disease phenotype to genetic factors. The IDDB is freely available at http://mdl.shsmu.edu.cn/IDDB/.

Abstract
Gut microbiota have been shown to promote oogenesis and fecundity, but the mechanistic basis of remote influence on oogenesis remained unknown. Here, we report a systemic mechanism of influence mediated by bacterial-derived supply of mitochondrial coenzymes. Removal of microbiota decreased mitochondrial activity and ATP levels in the whole-body and ovary, resulting in repressed oogenesis. Similar repression was caused by RNA-based knockdown of mitochondrial function in ovarian follicle cells. Reduced mitochondrial function in germ-free (GF) females was reversed by bacterial recolonization or supplementation of riboflavin, a precursor of FAD and FMN. Metabolomics analysis of GF females revealed a decrease in oxidative phosphorylation and FAD levels and an increase in metabolites that are degraded by FAD-dependent enzymes (e.g., amino and fatty acids). Riboflavin supplementation opposed this effect, elevating mitochondrial function, ATP, and oogenesis. These findings uncover a bacterial-mitochondrial axis of influence, linking gut bacteria with systemic regulation of host energy and reproduction.

Abstract
Background: Endometriosis is a frequently occurring disease in women, which seriously affects their quality of life. However, its etiology and pathogenesis are still unclear. Methods: To identify key genes/pathways involved in the pathogenesis of endometriosis, we recruited 3 raw microarray datasets (GSE11691, GSE7305, and GSE12768) from Gene Expression Omnibus database (GEO), which contain endometriosis tissues and normal endometrial tissues. We then performed in-depth bioinformatic analysis to determine differentially expressed genes (DEGs), followed by gene ontology (GO), Hallmark pathway enrichment and protein-protein interaction (PPI) network analysis. The findings were further validated by immunohistochemistry (IHC) staining in endometrial tissues from endometriosis or control patients. Results: We identified 186 DEGs, of which 118 were up-regulated and 68 were down-regulated. The most enriched DEGs in GO functional analysis were mainly associated with cell adhesion, inflammatory response, and extracellular exosome. We found that epithelial-mesenchymal transition (EMT) ranked first in the Hallmark pathway enrichment. EMT may potentially be induced by inflammatory cytokines such as CXCL12. IHC confirmed the down-regulation of E-cadherin (CDH1) and up-regulation of CXCL12 in endometriosis tissues. Conclusions: Utilizing bioinformatics and patient samples, we provide evidence of EMT in endometriosis. Elucidating the role of EMT will improve the understanding of the molecular mechanisms involved in the development of endometriosis.

Abstract
NEW FINDINGS What is the central question of this study? What are the potential therapeutic roles of ginsenoside Rb1 and hydroxysafflor yellow A (HSYA) in polycystic ovary syndrome (PCOS). What is the main finding and its importance? HSYA restored the oestrous cycles of PCOS mice, reduced follicular cysts in ovaries and rescued abnormal hormone secretion; ginsenoside Rb1 did not ameliorate the main symptoms of PCOS mice. HSYA alleviated oxidative stress along with an enhancement of antioxidant enzyme activity. This highlights a potential role of HSYA in PCOS therapy. ABSTRACT Polycystic ovary syndrome (PCOS) is the most common endocrine disease resulting in female infertility. Hydroxysafflor yellow A (HSYA) and ginsenoside Rb1 have been shown to have antioxidant properties, but little is known about their impact in PCOS. Here dehydroepiandrosterone was used to induce PCOS in a mouse model that was characterized by an irregular oestrous cycle, cystic follicles and an elevated serum testosterone level. Supplementation of HSYA restored the oestrous cycle of PCOS mice, reduced follicular cysts in PCOS mouse ovaries and brought about a decline in serum testosterone level, while ginsenoside Rb1 did not ameliorate the above symptoms of PCOS mice. After HSYA treatment, there was elevation of serum oestradiol, progesterone, luteinizing hormone and anti-Müllerian hormone levels and a reduction of follicle-stimulating hormone level, but ginsenoside Rb1 only rescued the levels of follicle-stimulating hormone and anti-Müllerian hormone. Further analysis evidenced that HSYA reversed the expression of steroid hormone secretion-related genes Star, Hsd3b1, Cyp11a1 and Cyp19a1. In PCOS mice HSYA weakened the elevation of ovarian malondialdehyde, which is regarded as a biomarker for oxidative stress. Moreover, HSYA improved reduced glutathione content accompanied by a simultaneous increase in reduced to oxidized glutathione ratio, and enhanced the activities of the antioxidant enzymes superoxide dismutase, glutathione peroxidase and catalase. Collectively, HSYA exerted beneficial effects on PCOS mice by restoring hormone secretion and alleviating oxidative stress.

Abstract
PURPOSE Endometriosis is one of the most common, difficult, and complicated gynecological disorders. Vascular cell adhesion molecule 1 (VCAM-1) has been reported to be aberrantly expressed in patients with endometriosis. However, the exact role and mechanism of VCAM-1 in endometriosis remains unclear. METHODS The expression of transforming growth factor beta 1 (TGF-β1) and VCAM-1 was determined by quantitative real-time polymerase chain reaction and western blotting. Human endometriotic cells were cultured and their responsiveness to TGF-β1 was evaluated by Cell Counting Kit-8, 5-ethynyl-2'-deoxyuridine, and transwell migration and invasion assays. RESULTS The levels of TGF-β1 and VCAM-1 mRNA were upregulated in the endometriotic tissues. Knockdown of TGF-β1 in endometriotic cyst stromal cells caused a marked inhibition of cell proliferation, migration, and invasion. Treatment of endometriotic cyst stromal cells with TGF-β1 resulted in an obvious promotion of cell proliferation, migration, and invasion, and strikingly increased the protein expression of VCAM-1. Silencing of Smad3 abated TGF-β1-stimulated VCAM-1 expression. Furthermore, the promoting effects of TGF-β1 on the proliferation, migration, and invasion of endometriotic cyst stromal cells were blocked by silencing of VCAM-1. CONCLUSION Knockdown of VCAM-1 impedes TGF-β1-mediated proliferation, migration, and invasion of endometrial cells, thereby indicating that VCAM-1 may serve as a therapeutic target for endometriosis.

Abstract
BACKGROUND Until now, an association between tissue inhibitor of metalloproteinase (TIMP) polymorphisms and primary ovarian insufficiency (POI) has not been identified. The aim of our study was to investigate whether the TIMP polymorphisms TIMP1T > C (rs4898), TIMP1G > A (rs6609533), TIMP2G > C (rs8179090), TIMP2G > A (rs2277698), TIMP3G > A (rs135029), and TIMP4T > C (rs3755724), which regulate matrix metalloproteinases (MMPs), confer a risk for primary ovarian insufficiency (POI) in Korean women (further studies would be required to evaluate the associations between TIMP polymorphisms and POI in other populations). METHODS We genotyped 137 POI patients and 236 controls for the single nucleotide polymorphism sites using PCR-RFLP analysis. Differences in the frequencies of the TIMP1T > C (rs4898), TIMP1G > A (rs6609533), TIMP2G > C (rs8179090), TIMP2G > A (rs2277698), TIMP3G > A (rs135029), and TIMP4T > C (rs3755724) genotypes between patients and controls were compared, and odds ratios and 95% confidence intervals were determined to measure of the strength of the association between the genotypes and POI. RESULTS The TIMP1T > C (rs4898), TIMP1G > A (rs6609533), TIMP2G > C (rs8179090), TIMP2G > A (rs2277698), TIMP3G > A (rs135029), and TIMP4T > C (rs3755724) genotypes, but especially the TIMP2 genotypes, were found more frequently in POI patients than in control subjects. Among the four TIMP loci, the TIMP1T > C (rs4898), TIMP1G > A (rs6609533), TIMP2G > C (rs8179090), TIMP2G > A (rs2277698), TIMP3G > A (rs135029), and TIMP4T > C (rs3755724) haplotypes were identified more frequently in POI patients than in control subjects and conferred susceptibility to POI (P <0.0001). CONCLUSIONS The TIMP2G > C (rs8179090) and G > A (rs2277698) alleles were strongly associated with POI. Our data suggest that the minor TIMP2 alleles may increase POI risk in Korean women.

Abstract
Cyst with relatively high recurrence and having nature to invade the underlying tissue is “odontogenic keratocyst (OKC).” Radiographically, OKC can appear as different varieties, such as follicular, replacemental, extraneous, envelopmental, and collateral. Each radiographic variety of OKC varies in biological behavior, prognosis, recurrence, and therapeutic approaches. Many studies done till date have not established any relationship between markers of proliferation and aggressiveness in regard to radiographic varieties of OKC. The present article reports a case of follicular OKC in an 8-year-old boy which was concluded as a dentigerous cyst by radiographic features.

Abstract
Aim To compare and evaluate morphological changes and bacterial deposits in primary carious molars after caries excavation with Carie-Care, erbium-doped yttrium aluminum garnet (Er:YAG) laser, and round tungsten carbide bur. Materials and methods Thirty human carious primary molars extracted for therapeutic reasons were sectioned mesiodistally. These sectioned samples were allocated into three groups (20 samples each): group I: Carie Care, group II: Er:YAG laser, and group III: round tungsten carbide bur. After caries excavation, all samples were processed and examined under conventional light microscope to examine for bacterial deposits. Representative samples from each group were processed and analyzed to examine the morphology of caries-excavated tissue by scanning electron microscope (SEM). Statistical analysis was done using Fisher’s exact test, Kruskal–Wallis test, and Mann-Whitney U test. Results The Er:YAG laser showed best results with no smear layer followed by chemomechanically excavated surfaces with Carie-Care. Amount of bacterial deposits was observed to be more in group I while least in group II (p-value < 0.001). Mann-Whitney U test and Fisher’s exact test revealed that there was statistically significant difference among all the three groups. Conclusion Among the three different methods of caries excavation, Er:YAG laser was found to be more effective compared with Carie-Care and round tungsten carbide bur. Clinical significance Laser-induced caries excavation by Er:YAG laser and chemomechanical method of caries removal by Carie-Care can be considered as future of noninvasive pediatric and preventive dentistry.

Abstract
Aim Two eruption surgical techniques are commonly described for the treatment of upper impacted central incisors (ICIs): Open and closed. Currently, the closed-eruption surgical technique (CEST) is the most commonly used, as it allows for the best esthetic and periodontal results. The aim of this study was to determine the effect of traction discontinuation on maxillary central incisor sulcal depth and alveolar bone ridge levels compared with contralateral incisors, when CEST is used. Materials and methods Our study involved 28 unilateral impacted maxillary central incisors treated by CEST. Thirteen teeth were subjected to traction interruption for a month at the time of emergence of the crown, while 15 teeth underwent continuous traction. One year after treatment, periapical digital X-rays, anterosuperior cone beam computerized tomography (CBCT) scanning, and periodontal probing of the ICIs and contralateral central incisors (CCIs) were performed. Student’s t-test was used to study whether a statistically significant difference between continuous and interrupted tractions takes place while using the CCI measurements as reference. Results There was a statistically significant difference between the two techniques only for the following measurements: Mesial probing (p-value 0.039352), labial bone level (p-value 2.58E-08), and palatal bone level (p-value 2.56E-06). Limitations A larger sample size and longer term follow-up are needed to draw more robust conclusions. Conclusion A temporary discontinuation during traction of the tooth appears to positively impact treatment outcome on ICIs. Clinical significance • The CEST leads to the best periodontal status for ICIs. • The discontinuation of traction at the emergence of the tooth allows the supracrestal fibers to insert into the cement in a proper way.

Abstract
Aim and objectives Aim of the study was to evaluate the success of magnetic nanoparticles (MNPs) as pulpotomy medicament by clinical, radiologic, and histological assessment in primary molars. Materials and methods The sample included 30 primary molars from 25 children aged between 3 and 9 years requiring pulpotomy treatment. Pulpotomy was carried out with MNPs. The teeth were evaluated after a period of 3, 6, and 12 months clinically and with the aid of radiographs. After 1 year, 10 teeth were extracted for histological evaluation under field emission scanning electron microscope (FE-SEM; ZEISS, Model No. Supra 55vp). Results Of the samples, 98% showed clinical success rate with absence of pain, swelling, mobility, and abscess formation. After 3 months, 98% radiological success with absence of periodontal ligament widening, root resorption, and inter-radicular radiolucency was noted. Histological examination carried out under FE-SEM revealed a zone of odontoblastic proliferation at the interface between MNPs and odontoblastic layer of pulp and viable pulpal cells from the canal orifice till apical foramen. Conclusion Magnetic nanoparticles can be recommended as an effective pulpotomy medicament with hard tissue barrier formation and preservation of vitality of remaining radicular pulp.

Abstract
Aim The purpose of this study was to evaluate the surgical options for supernumerary teeth (SNT) in the premaxillary region of children. Materials and methods A total of 69 patients with 82 partially or completely formed SNT in the anterior maxillary region were identified over a 3-year period. All selected patients were assessed for the number, location, and family history of SNT, damage to adjacent roots, and associated symptoms. The surgical approaches used for removal were recorded. Postoperative clinical sequelae (loss of vitality, periodontal problems, pain, bleeding, and enanthema) were evaluated. Results A total of 43, 30, and 9 SNT were extracted with palatal, buccal, and bicortical approaches respectively. Peri-odontal and vitality assessments revealed no problems in adjacent teeth at 6 months after surgery. Postoperative pain was within acceptable levels in all patients and subsided within 3 to 7 days. Mild postoperative bleeding occurred in eight patients. Enanthema subsided within 10 days in all patients. Conclusion Our results suggest that early diagnosis and appropriate surgical treatment of SNT are important to decrease the risk of clinical complications.

Abstract
Cumulus cells (CCs), the granulosa cells surrounding the oocytes, play critical roles in oocytes maturation through intercellular communication by extending trans-zonal projections (TZPs) to contact oocytes via gap junctions (GJs). The adverse effect of heat stress (HS) on oocyte maturation has been well documented, whereas the HS responses of CCs and the oocytes in association with GJ/TZP colocalization remain unclear. In this study, porcine cumulus-oocyte complexes (COCs) were subjected to HS at 41.5°C for 24 hr during in vitro maturation. Cumulus expansion was impaired and oocyte quality was reduced with lower survival rate, polar body extrusion rate, and early embryo developmental potentials. CCs and oocytes isolated from COCs demonstrated distinct responses to HS. The messenger RNA abundance of heat shock protein-related genes and mitochondrial DNA-encoded genes, together with ATP content, were significantly increased in CCs, yet decreased in oocytes, despite activation of caspase 3 detected in both CCs and oocytes. Similar changes were observed when denuded oocytes and isolated CCs subjected to HS separately, except mitochondria reactive oxygen species (mROS). In heat-stressed COCs, mROS was significantly increased only in oocytes. However, when isolated CCs and denuded oocytes were heat-stressed separately, mROS was significantly increased only in CCs. Moreover, F-actin, a TZP marker, and its colocalization with a GJ protein connexin-45, were significantly reduced in heat-exposed COCs. These results indicate that HS induces distinct responses in porcine CCs and oocytes in association with disrupted GJ and TZP colocalization.

Abstract
The most recent evidences suggest the use of progesterone mimicking drugs for the treatment of endometriosis. Particularly, dienogest has been largely tested. However, the standard treatment of extra-pelvic endometriosis is debated. Particularly, cerebral localization of endometriosis is a very rare clinical condition. The surgical approach for such a particular disorder would consist in difficult procedures, thus leading to prefer the medical treatment. We hereby report the clinical case of a cerebral localization of endometriosis treated with dienogest who experienced a complete remission of the disease.

Abstract
Aim To evaluate the microtensile bond strength of teeth restored with packable composite after removing caries with three chemomechanical caries removal agents (Carisolv, Papacarie and Carie-care) and also to analyze its effect on chemical composition of dentin using energy-dispersive X-ray (EDX) analysis. Design A total of 40 carious molars with 1 to 1.5 mm of remaining dentin were selected and divided into four groups of 20 each. Group I (control)—bur, group II—Carisolv, group III—Papacarie, group IV—Carie-care. A total of 15 samples from each group were restored with composite; 1 mm thick sections were made and were debonded under tensile load. Remaining five samples from each group were subjected to EDX for elemental analysis of dentin surface. Results No statistically significant difference in the bond strength values and Ca/P ratio was observed between control group and three chemomechanical agents tested in the study. Conclusion None of the chemomechanical agents tested in the study adversely affected the bond strength of composite resin to caries-affected dentin. Therefore, newer papain-based chemomechanical agent Carie-care can be considered as an equally effective economical alternative to commonly used agents Carisolv and Papacarie.

Abstract
Aim Oral habits during and beyond preschool age are one of the important etiological factors in developing malocclusion and other ill effects on orofacial structures. The objective of the present study was to know the prevalence of deleterious oral habits among 3- to 5-year-old preschool children in Bhubaneswar, Odisha, India. Materials and methods This cross-sectional study was conducted among preschool children, in the age group of 3 to 5 years in the city of Bhubaneswar, Odisha, India. To carry out this study, six private schools, two from each of the three electoral constituency, were selected using cluster sampling technique. A total of 500 students, studying in LKG and UKG and their respective mothers/caregivers were selected for the study as per the inclusion/exclusion criteria. Prevalence of different oral habits in children was calculated from the data obtained. Using Statistical Package for the Social Sciences (SPSS), version 17.0 software, Chi-square test was applied to compare the differences present between boys and girls and their significant values (p < 0.05). Results The result of this study showed a high prevalence of oral habits (36%) among preschool children in Bhubaneswar, Odisha, India. Lip biting was found to be the most prevalent habit (13.4%), followed closely by thumb sucking (12.8%), bruxism (12.8%), and mouth breathing (11%). Conclusion The study revealed a great dearth of a well-established dental education program for preschool children as well as their parents, caretakers, teachers, and pediatricians in order to provide an effective and timely care to the children.

Abstract
Trauma is a common cause of fractured teeth with exposed canals in growing children. These children use foreign bodies like stapler pin, lead pencil, nail, etc., to explore the canal of fractured tooth. Sometimes, these foreign objects may get stuck in the canal, which the children do not reveal to their parents because of fear. These foreign objects may act as a potential source of infection. We herewith present a case of a 12-year-old boy who presented with a stick lodged in the root canal of maxillary right lateral incisor along with the displaced fractured tooth segment at the apex and the associated management.

Abstract
Objectives The objective of this in vitro study was to assess the surface hardness through Vickers hardness (VH) test of one conventional hybrid resin composites (Filtek Z350), compared with that of two bulk cure resin composites (SDR™, Tetric N Ceram®). Materials and methods Twenty specimens of each material were prepared in cylindrical aluminum molds with an internal diameter of 5 mm and depth of 4 mm, 10 (incremental curing) and 10 (bulk curing). The surface of each specimen was covered with a transparent plastic matrix strip before light curing with conventional visible light for 40 seconds. The specimens thus obtained were stored in deionized water and transferred to an incubator at 37°C for 24 hours to simulate clinical conditions. After 24 hours, the microhardness of each specimen was measured using a Vickers indenter, with a load of 100 gm and dwell time of 15 seconds (HV 0.2/40). The specimens were further subjected to VH test in an interval of 7, 30, and 90 days. The data were subjected to statistical analysis—Student’s t test, analysis of variance, and post hoc Tukey’s test. Results The present study showed that SDR™ in bulk curing showed consistently greater value of hardness and was comparable to traditional incremental cured Filtek Z350, highlighting the advantages of the new SDR technology.

Abstract
Aim Parental presence often provides unique challenge in dental operatory and is directly related to the quality dental treatment. The present study was done to investigate parent's ability to assess dental anxiety of their 6- to 10-year-old child and to determine how parent's and children's fear assessments correlate with each other. Materials and methods Prior to dental treatment, 94 child-parent combinations were included to complete Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) questionnaire, and Frankl score was assigned to children during treatment by operator. Results Mean dental anxiety score reported by the children was 27.74, whereas by their parents was 39.64. There was a poor consistency of parents to predict their child dental fear (p < 0.05). Parents reported higher dental fear for their children. Conclusion Parents assessment of their child's fear may vary in accordance to factors, including their own dental fear. Such input may prevent dentists from establishing an accurate association with the child's patient.How to cite this article: Malhotra R, Gandhi K, Kumar D, Ahuja S, Kapoor R, Sahni A.

Abstract
Context Eruption of teeth is influenced by various factors. Very few studies were carried out in the past on the eruption time of teeth in the Indian population. Aim The aim of the study is to determine the time and sequence, gender differences, pattern of symmetry in the eruption of permanent teeth in Hyderabad children. Materials and methods In this cross-sectional study, 1654 schoolchildren (806 girls and 848 boys) in the age group of 5 to 15 years from Hyderabad were examined for the status of eruption of permanent teeth. Statistical analysis used Results were subjected to probit’s regression analysis. The average age at eruption of permanent teeth, excluding third molars, was given as the mean [± standard deviation (SD)] in months for each gender. A table of percentiles of the eruption time was also determined. Results Unlike most of the earlier studies which showed that girls are ahead of boys in permanent teeth emergence, no such pattern was observed. No significant difference was found in the eruption of permanent teeth in right and left arches. Eruption of all the mandibular teeth, with the exception of right first premolar (44) in both the genders, was earlier than their maxillary counterparts. There was overall delay in the eruption of permanent teeth and significant delay in the eruption of lower canines in both genders. Conclusion The significant delay in the eruption of permanent mandibular canines is relevant for orthodontic treatment planning.

Abstract
Papillon-Lefèvre is an autosomal recessive syndrome that starts in early periods of childhood. Characteristic features include palmar plantar hyperkeratosis, aggressive periodontal disease, and a tendency for dry and chopped skin, thin and sparse hair. Patients show signs of premature tooth loss at the age of 2 to 4 years, which is then followed by the loss of permanent dentition during adolescence. The presence of both skin and oral lesions in this syndrome differentiates this unusual genodermatosis from other pathology of palmoplantar keratoderma (PPK). The etiopathogenesis of this syndrome is somewhat obscure; however, immunologic, genetic, and possible bacterial etiologies have been proposed. The dental practitioner is often the first to diagnose the disease, as there is a significant degree of periodontal breakdown that is involved at an early age. This report presents a clinical presentation of two brothers detected with Papillon-Lefèvre syndrome (PLS). How to cite this article: Fageeh HN.

Abstract
Introduction The study was conceived to formulate a tool to evaluate child perceptions related to oral health in 11- to 14-year-olds tailor-made for Indian children in Hindi. The original child perceptions questionnaire (CPQ11-14) was translated into Hindi and it was tested for validity and reliability. Materials and methods The original CPQ11-14 was translated into Hindi and some questions were rephrased to suit the sociocultural situation in India. The domains of self-esteem and psychological well-being were added to the questionnaire to broaden the scope of parameters to thoroughly assess the impact on child perceptions toward oral health. The English and Hindi versions of the CPQ11-14 were administered during the first visit to test for validity and the children were recalled after 1 week and administered the Hindi questionnaire again after 1 week to check for reliability. Results The results showed significant positive correlation between oral symptoms, decayed, missing and filled teeth (DMFT) functional limitation and malocclusion. The mean functional limitation score was found to be higher in subjects with malocclusion in both the English and Hindi questionnaires. The test-retest samples were evaluated using the paired t-test and showed no significant difference between the first and second administration which suggested good reliability. Conclusion The translated and modified Hindi CPQ11-14 was found to be valid and highly reliable for use in India. The adaptation of the original questionnaire by modifying certain questions to suit the Indian condition was found to be culturally relevant.

Abstract
Aims and objectives To determine and compare the effect of triphala, chlorhexidine gluconate, and garlic extract mouthwash on salivary Streptococcus mutans count and the oral hygiene status. Materials and methods Sixty children aged 9 to 12 years were randomly allocated into the study groups of triphala mouthwash, chlorhexidine mouthwash, garlic extracts mouth-wash, and distilled water mouthwash. Examination included decayed, missing, and filled teeth (dmft)/decayed, missing, filled surface (dmfs) and DMFT/DMFS, plaque index, and S. mutans count on days 1, 15, and 30. Results The results were statistically analyzed using Friedman test, Wilcoxon signed rank, repeated-measures analysis of variance (ANOVA), paired t-test, one-way ANOVA, post hoc Tukey’s honestly significant different (HSD), Kruskal–Wallis test, and Mann-Whitney test; all calculations were done by MEDCALC software 14.0.0 version. Discussion Streptococcus mutans count had significant reductions using different mouthwashes at 15 days, but the chlorhexidine group showed significant difference from the remaining three groups. Intergroup comparison for plaque index scores of triphala, chlorhexidine, and garlic groups was similar in preventing plaque build-up during the 15 days of mouthwash use. Conclusion All the three mouthwashes containing triphala, chlorhexidine gluconate, and garlic were comparably efficient in reducing the salivary S. mutans count as well as in limiting plaque score; however, chlorhexidine was the most effective in this aspect. In comparison of the two natural ingredients, Triphala is more effective in its antimicrobial effect. How to cite this article: Padiyar B, Marwah N, Gupta S, Padiyar N.

Abstract
Introduction Children depend on their parents and caretakers for maintenance of their oral health. Parents play a major role in both preventive and treatment regime in these children. This study was conducted with the aim of evaluating the influence of parental education on knowledge, attitude, and practice of mothers regarding oral health of primary schoolchildren in Chennai. Materials and methods A 15-item self-administered questionnaire was used among 465 parents of preschool children in Chennai, of which 432 mothers returned the filled questionnaire. The data collected were subjected to statistical analysis using frequency of responses and chi-square test (p < 0.01). Data were analyzed using statistical package. Results Of the 432 mothers who participated in the study, 150 (35%) have studied up to school level and 282 (65%) have completed diploma/degree. The knowledge of mothers regarding the knowledge of importance of oral health for general health is appreciable, but the awareness of proper brushing habit, treatment of caries, and importance of dental visits is less in mothers who have school education when compared with graduate mothers. Conclusion Mothers who are graduates are more aware of the importance of oral health in children, treatment of dental caries, and brushing technique than mothers with school education. Hence, it is essential that government and health care providers impart oral health knowledge to mothers, as they are the role-models for their children.

Abstract
Introduction Usually discomfort and pain are associated with dental work, especially for young patients. Pain control can be achieved by using anesthesia. Sight of injection can terrify any patient and if the patient is a child it is really difficult to convince them for injections. Alternatives to injections have been explored. Pediatric dentists are using anesthesia in the form of jelly and patch. Recently, the concept of mucosal vibration has been put forward to enhance the effectiveness of local anesthesia. Aim The aim of the present study was to compare and evaluate the effectiveness of lignocaine jelly and mucosal vibration in reducing pain during administration of local anesthesia in pediatric dental patients. Materials and methods Thirty children in the age group 6 to 11 years who required bilateral anesthesia for dental treatment in mandible were selected for this study. Pain was compared using Wilcoxon signed-rank test at the time of injection using Sound, Eye, Motor (SEM) scale as objective criteria and facial pain rating (FPR) scale as subjective criteria after administration of injection by a trained assistant who was blinded to the procedure. Results Local anesthetic injection along with mucosal vibration resulted in significantly less pain (p = 0.001) in comparison with the injections without the use of mucosal vibration. Conclusion The result shows that mucosal vibration can be used as an effective means to reduce the intensity of pain during local anesthetic injection in dentistry.

Abstract
Background Patients with class II malocclusion generally seek orthodontic treatment for esthetic concern. Various myo-functionl appliances can be used for the treatment of skeletal as well as the dental malocclusion in a growing patient. Among various functional appliances, twin block appliance is most commonly used due to better patient compliances. It redirects the mandibular growth to correct the maxillomandibular relationship, enhancing facial esthet ics. This article presents a modified design of the twin block appliance which is less bulky, more esthetic, can be used concurrently with fixed orthodontic appliance, and is easily accepted by uncooperative patients. Case summary An 11-year-old-boy, who presented himself with a skeletal class II malocclusion, was treated with simultaneous use of fixed twin block along with fixed orthodontic appliance to correct both the skeletal and dental malocclusion. The twin block design was modified to have a better compatibility with the fixed orthodontic appliance. How to cite this article: Pattanaik S, Puvvula N, Mohammad N.

Abstract
Dental caries is a disease of multifactorial origin and Streptococcus mutans is considered as the chief pathogen responsible for its development. However, reduction in the number of pathogenic bacteria, particularly S. mutans, with the use of various preventive measures, can reduce dental caries to a significant level. Therefore, the present clinical study was undertaken to evaluate and compare the efficacy of toothbrushing, fluoride varnish, chlorhexidine mouthwash, and a probiotic (Yakult) in reducing the S. mutans counts in the saliva using Dentocult SM Strip Mutans kit in children. A total of 40 school students between the age group of 4 and 8 years were selected for the study and S. mutans count was taken on the first dental visit using Dentocult SM Strip Mutans test kit. After the initial scores of S. mutans were obtained, the children were divided into four groups and provided with different caries preventive regimen for 2 weeks. After 2 weeks, the scores of S. mutans were reevaluated for reduction in their counts, if any. The data thus collected were tabulated and statistically analyzed. All the groups showed a significant reduction in S. mutans counts with the highest reduction from the Fluor Protector varnish followed by chlorhexidine mouthwash, probiotic (Yakult), and toothbrushing.

Abstract
Aim The aim of the study was to test the antibacterial activity of manuka honey and compare its efficacy with another commercially available honey (Dabur honey) on the cariogenic bacteria on Streptococcus mutans and Lactobacillus. Materials and methods An in vitro study was carried out on 40 agar specimens; the samples were divided into two groups of 20 samples consisting of S. mutans and Lactobacil-lus respectively. The 20 samples in each group were further subdivided into four groups of five each, which were tested with 25% manuka honey, 100% manuka honey, 25% Dabur honey, and 100% Dabur honey for both Lactobacillus and S. mutans groups. The antibacterial activity was tested using the agar well diffusion method against S. mutans and Lacto-bacillus. Antibacterial activity was assessed by measuring the diameter of inhibition of zones surrounding the wells. The results obtained were statistically analyzed (one-way analysis of variance test, p-value). Results The results showed that 25% of manuka honey has statistically significant (p ≤ 0.001) antibacterial effect than 25% of Dabur honey on both Streptococcus and Lactobacillus species, and manuka honey with 100% concentration showed a statistically significant (p ≤ 0.001) antibacterial effect than 100% Dabur honey on the same species of bacteria. 100% of both the honeys showed statistically significant (p ≤ 0.001) antibacterial effect than 25% concentrations of the same on S. mutans and Lactobacillus. Conclusion Manuka honey had more antibacterial activity than Dabur honey on S. mutans and Lactobacillus bacteria in the in vitro study. This effect was dependent on the concentration of honey used.

Abstract
Aim To determine the perception of Indian dental professionals about prevalence, severity, and etiological factors of molar incisor hypomineralization (MIH). Materials and methods An online survey was mailed to dental professionals encompassing various questions regarding etiology, diagnosis, prevalence, and management of MIH. Results More than 90% of the respondents encounter teeth with hypomineralization in their practice, with less than half of them encountering such teeth on a monthly basis. Among these more than one-third find it difficult to manage one or the other aspect of MIH. The etiology was found to be varying as per the respondents. Conclusion Molar incisor hypomineralization is a common condition encountered by dental professionals with no apparent consensus regarding the anticipated prevalence, severity, and etiology of this condition. Knowledge of clinicians' level of perception could be an incentive for pediatric dentists to become more acquainted with MIH by conducting research into its different aspects.How to cite this article: Upadhyay S, Kumar G, Dhillon JK, Gill NC.

Abstract
Oral habits in the form of thumb sucking and tongue thrusting are commonly learned patterns of behavior seen in preschool children and they are associated with anxiety, fear, hunger, oral pressure, and sleep. Chronic practice can cause dentoalveolar, perioral problems, and atypical root resorption (ARR) of anterior primary teeth. The ARR is provoked by the thumb sucking habit, and leads to early loss of anterior primary teeth. The early loss of anterior tooth may result in speech and masticatory problems, and psychological disturbance to the child. Hence, pediatric dentists play a crucial role in giving necessary information to parents and guardians. Starting from counseling to appliance therapy, various treatment modalities have been reported in the literature. One of them is bluegrass appliance; it is a nonpunitive habit reminder therapy. The present case report describes a customized hybrid bluegrass appliance designed to eliminate thumb sucking and tongue thrusting habit, and to perform as an esthetic functional space maintainer.

Abstract
Hepatocellular carcinoma (HCC) is highly incidental in South Asian countries. Nepal, however, has low incidence for HCC owing to low prevalence for hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. Nepal lacked national cancer registry until 2003. Though there has been some effort in having one, the current registry incorporates twelve centers and may not properly represent the total cancer burden in the country. Serology for HBV and HCV is seen to be positive in nearly 25 to 30% and 5 to 10% of HCCs respectively. Clinical characteristics of HCCs in Nepal have been discussed in this mini-review and it features poor performance status and advanced stage at presentation, making only a small fraction of these subjects eligible for curative treatment options. Most of the standard treatment modalities are available in Nepal and appear to be reasonably affordable as compared with other developed nations. How to cite this article: Shrestha A.

Abstract
Introduction The term multiple primary tumor (MPT) is used to describe cases where two or more primary tumors show no histopathological similarities in between. Multiple primary tumor cases have begun to increase in recent years as a result of the increase in life expectancy because of the increase in life standards and progress in diagnostic methods. In this study, MPT cases with periampullary tumors that underwent Whipple procedure were discussed in the light of literature data. Materials and methods The patient files of 223 cases with periampullary tumors that underwent Whipple procedure in our hospital during the last 6 years were examined retrospectively. More than one primary tumor was detected in 21 patients. Results Periampullary carcinomas were detected as a second primary tumor in 18 patients. First primary tumor was periampullary carcinoma in 3 patients that underwent Whipple procedure. After the Whipple procedure, 5 patients died due to early complications in the first 30 days and 6 patients died due to metastases and additional problems that developed during follow-up. Discussion The incidence of MPT has been reported as 0.7 to 14.5% in the literature. Most of them are multiple primary case presentations. In patient management, it is recommended that each tumor should be evaluated independently of its own characteristics, and treatment and follow-up should be planned accordingly. Conclusion The MPT cases are increasing. The possibility of MPT as well as metastasis should be kept in mind during the evaluation of tumor foci seen during diagnosis and follow-up of patients. The characteristics of each tumor, survival, and prognosis should be evaluated separately and the most appropriate treatment should be offered to the patient. It is recommended that synchronic primary tumors which are considered to be surgically resectable without metastasis should be removed in the same session.How to cite this article: Dilek ON, Ozsay O, Karaisli S, Gür EÖ, Er A, Haciyanli SG, Kar H, Dilek FH.

Abstract
The seroprevalence of hepatitis B virus (HBV) surface antigen (HBsAg)-positive blood donors was 8.7%. The prevalence among males (9.7%) was higher than among females (6.2%). The prevalence of antihepatitis C virus (HCV)-positive blood donors was 1.1%, with no significant differences between males (1.1%) and females (1.0%). Annual positive rates for HBsAg and anti-HCV donors during the years 2003 to 2005 did not differ significantly. In Lao People’s Democratic Republic (PDR), HBV is highly endemic. However, blood donations are only screened for HBsAg, leaving a risk of transmission by HBsAg-negative occult infected donors. Here, we characterized first-time blood donors to assess prevalence of HBV infections and occult infected donors. Despite hepatitis B vaccination at birth and at 6, 10, and 14 weeks of age, HBV infection continues to be endemic in Lao PDR. We carried a cross-sectional serological study in infants, preschool children, school pupils, and pregnant women to determine their burden of disease, risk of infection, and vaccination status. The prevalence of HBsAg carriage in pregnant women is a relevant marker for the risk of mother-to-child HBV transmission. This study aimed to assess the changes in prevalence of HBV infection among pregnant women attending Mahosot Prenatal Clinic (Vientiane). How to cite this article: Ounavong A.

Abstract
Introduction Liver involvement is common in hematological malignancies, but the incidence and pattern of liver injury vary among the different types. The aims of our study were to determine the incidence and clinical course of acute hepatitis and the important factors for its development in patients with leukemia after chemotherapy. Materials and methods All patients with the diagnosis of leukemia who were treated at the Department of Hematology between January 2008 and January 2013 were included in the study. A detailed medical history, clinical and laboratory findings, treatment modalities, complications, and clinical course were recorded retrospectively. Results A total of 124 patients (64 females) with the diagnosis of leukemia were included in the study. The mean age was 45.2 years (16-89 years) and mean follow-up time was 29.7 months (0.25-192 months). A total of 43 (34.6%) patients had acute hepatitis after chemotherapy. Pattern of liver injury was hepatocellular in 31 patients, cholestasis in 2, and mix in 10 patients. Age (p = 0.001), hepatitis B surface antigen (HBsAg, p = 0.007), acute leukemia (p < 0.001), positive blood culture (p = 0.004), the amount of transfused red blood cell (p = 0.001), and amount of transfused platelets (p = 0.002) were significantly different under univariate analysis between the acute hepatitis group and the nonacute hepatitis group. Under multivariate analysis, only acute lymphoblastic leukemia (ALL) was identified as independent predictive factor for development of acute hepatitis after starting chemotherapy. Conclusion Acute and self-limited hepatitis develops in the substantial proportion of patients with leukemia. The most important factor for development of acute hepatitis is the type of leukemia.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is becoming one of the most important causes for chronic liver disease and also hepatocellular carcinoma (HCC) in Sri Lanka. This tendency is also recognized worldwide. More than half of the middle-aged and elderly adults in urban Sri Lanka have ultrasonic evidence of NAFLD. The NAFLD is also identified in population from rural areas of Sri Lanka and also in children. Nonalcoholic steatohepatitis (NASH) cirrhosis is the most common cause of referral for liver transplantation in Sri Lankans. The NASH is also the most common cause for rejecting potential donors for liver transplantation in Sri Lanka. Patients who underwent liver transplantation for cryptogenic cirrhosis developed evidence of NASH following liver transplantation. Recent evidence suggests that there is a genetic component to NAFLD. PNPLA3, a single gene polymorphism linked to the short arm of chromosome 22, is associated with the severity of NAFLD. The presence of this genetic polymorphism appears to carry higher risk of patients with NAFLD developing NASH with fibrosis cirrhosis and hepatocellular carcinoma. In a large population-based study from Sri Lanka, there was a tendency to develop NAFLD associated with this genetic polymorphism. In a population-based study, NAFLD was identified as an independent risk factor for development of diabetes. This association is recognized worldwide now. Most patients with HHC in Sri Lanka developed it on a back ground of cryptogenic cirrhosis. At the same time, the prevalence of the markers for hepatitis B and C was rare in Sri Lankan patients with HCC. How to cite this article: Dassanayake AS.

Abstract
Aim This research focused on the results of the cross-validation program related with the performance of a Cuban novel low-cost real-time quantitative polymerase chain reaction (qPCR) assay for hepatitis B virus (HBV) quantification developed by the Therapeutic Vaccine against Hepatitis B Department, Vaccines Division, Center for Genetic Engineering and Biotechnology (CIGB), Havana, Cuba. Materials and methods Dilution series with the plasmid standard at concentrations of 900,000 to 0.09 copies/reaction (c/r) were made for each PCR instrument. The mean cycles threshold (Ct) values and PCR efficiency were compared among the cyclers. Hepatitis B virus-positive serum samples were used for the calculation of reproducibility of the HBV assay. Biotecon Diagnostics (BCD) also ordered the oligo sequences from a second supplier and compared the PCR performance to those provided from the CIGB. Results All PCR cyclers were able to detect concentrations up to 0.09 c/r. However, below the concentration of 9 c/r, the variation of results increased within and between the cyclers. The PCR efficiency showed satisfying results. The overall coefficient of variation (CV) cycler values were 1.29 and 0.91% for M6 and M19 respectively. No significance was observed between the different primer suppliers. Conclusion The HBV assay was performed with a good concordance between the five real-time instruments from different suppliers. The HBV assay was also performed with a high reproducibility for samples with a high and a low viral load. The HBV assay is robust against different primer suppliers.

Abstract
AIM The goal of the study was to detect the presence of macrophage inflammatory protein (MIP)-1α and MIP-1β and to estimate their levels in gingival crevicular fluid (GCF) of children with Down syndrome. MATERIALS AND METHODS MIP-1α and MIP-1β levels were estimated in GCF samples of 20 healthy and 20 Down syndrome individuals. Gingival status was assessed by measuring the gingival index (GI), plaque index (PI), clinical attachment level (CAL), and probing pocket depth (PPD).The GCF samples were obtained from the subjects and MIP-1α and MIP-1β levels were quantified by enzyme-linked immunosorbent assay (ELISA). RESULTS The mean MIP-1α concentrations in healthy and Down syndrome individuals were 209 and 1411 pg/μL respectively, and MIP-1α levels were 342 and 1404 pg/μL respectively.The levels of MIP-1α and MIP-1β in the GCF of subjects with Down syndrome were significantly higher than in the healthy individual, and statistically significant differences were present among the two groups. CONCLUSION The GCF showed dynamic changes according to the severity of periodontal disease, and the levels of MIP-1α and MIP-1β had a strong relationship with clinical parameters. The MIP-1α and MIP-1β can therefore be considered as novel biomarkers in the biological mechanism underlying the patho-genesis of periodontal disease.How to cite this article: Reddy VK, Kommineni NK, Padakandla P, Togaru H, Indupalli JP, Nanga SP.

Abstract
Composites polymerized with a clear matrix on the surface will leave a resin-rich surface layer that is easily abraded in the oral environment, exposing unpolished, rough, inorganic filler material. The purpose of this study was to evaluate the polishing effect of two different polishing systems: One-step (PoGo) system and Sof-Lex (multistep) system on four different resin composites: Synergy D6, Clearfil APX Esthetics, Filtek Z 350 XT, Ceram X Mono. After polishing, the specimens were analyzed for average surface roughness using a two-dimensional surface profilometer. How to cite this article: Garg S, Goel M, Verma S, Mahajan N, Kaul B, Garg V.

Abstract
Introduction To ascertain differences in intraocular pressure (IOP) measurement and their repeatability between dynamic contour tonometry (DCT) and Goldmann/Perkins applanation tonometry (GAT) at two different atmospheric pressures. Materials and methods Forty-one eyes of 41 healthy consenting subjects were enrolled for this observational, cross-sectional study. Pachymetry and IOP measurements with DCT and GAT for both eyes of each subject at Acapulco (0 m from sea level) and at Mexico City (2,234 m from sea level) were done by the same observer. The IOP was compared between tonometers at each of the altitudes, and also for repeatability of each tonometer at different altitudes. Pearson's correlation coefficient and Bland-Altman plots were used to assess reliability of measurements and their differences at the two altitudes. Results The mean age of patients was 41.7 (28-66 years); 22 were females. Mean IOP with DCT was 16.1 ± 2.2 mm Hg at sea level and 15.9 ± 2.1 mm Hg at 2,234 m above sea level, not a significant difference. Mean GAT IOP at the two altitudes was 13.1 ± 1.8 and 11.5 ± 1.7 mm Hg respectively, a statistically sig -nificant difference. In contrast, central corneal thickness (CCT) was not significantly changed (548.3 to 549.4 μm, p = 0.496). Conclusion Repeatability of single-observer measurements with GAT remains clinically acceptable, but not at different altitudes. The DCT seems to more consistently measure a similar IOP at different altitudes in the same subjects. The two tonometers may not be used interchangeably in the serial follow-up of patients at any of the altitudes.How to cite this article: Albis-Donado O, Bhartiya S, Gil-Reyes M, Casale-Vargas G, Arreguin-Rebollar N, Kahook MY.
