J Educ Health Promot 2020 31;9:207. Epub 2020 Aug 31.

Department of Paedodontics and Preventive Dentistry, Faculty of Dentistry, Asian Institute of Medicine, Science and Technology University, Kedah, Malaysia.

Aim: This study was intended to evaluate the knowledge and attitudes regarding infant's oral health care among graduating medical students from Kulasekaram, Tamil Nadu.

Materials And Methods: A cross-sectional survey research design was employed in this study. Self-administered questionnaire of the validated "Graduating medical students' Knowledge and Attitudes Survey Regarding Infant's oral health care" were utilized to ascertain the baseline levels of knowledge and attitudes of graduating medical students' in Kulasekaram hospital. In this regard, a preliminary study with a convenience sample of 100 medical students was conducted so as to assess the knowledge of infant oral health care among graduating medical students in Kulasekaram. This study, while limited in sample size, benefits the general practitioners as target readers to assess the abnormalities in children at early stages of life.

Results: The results of the study revealed that the mean percentage score overall was 65.7%. Only 3.2% of participants obtained a passing score of 80% or greater. Widespread knowledge deficits and poor attitudes among graduating medical students were noted in this study, particularly in the domain of pharmacological management of pain. Positive correlations were observed between the respondents' score and level of education. Further analysis revealed respondents had an inaccurate self-evaluation of their pain management knowledge.

Conclusion: The results of this study reveal that there is dearth of knowledge and attitudes of graduating medical students' regarding infant oral health care. Educational and quality improvement initiatives in oral health care of infants could enhance medical student's knowledge baseline in the area of oral health care and possibly improve practices.

Intentional replantation with 180° rotation of a complicated crown-root fracture: A Case Report.

Trauma Case Rep 2020 Jun 11;27:100306. Epub 2020 May 11.

Sri Sankara Dental College, Varkala, Kerala, India.

Complicated crown root fractures are mostly difficult to treat and have a poor prognosis. To restore the biological space, intentional replantation may be chosen when other immediate treatment options are not viable. Intentional replantation with tooth rotation consists of extraction, 180° rotation and replantation, thereby maintaining the biological width. This article presents management of a maxillary central incisor with complicated crown root fracture with open apex. The tooth was rotated and splinted for one week. The apex was closed with mineral trioxide aggregate (MTA) followed by obturation and post placement. The incompletely obturated adjacent tooth was non-surgically managed by retreatment. Finally, glass fibre post followed by crown with indirect composite built up was made. Patient was followed up every three months for the next two years without any complications.

Comparative Evaluation of Erosive Potential of Various Frozen and Unfrozen Fruit Juices on Primary Teeth Enamel: An Study.

J Pharm Bioallied Sci 2019 May;11(Suppl 2):S463-S467

Faculty of Dentistry, Asian Institute of Medicine, Science and Technology (AIMST) University, Kedah, Malaysia.

Background: Changing lifestyle pattern and food habits has a deteriorating effect on dental tissues. Dental erosion is a pathological wear of hard tissues of teeth with increased consumption of acidic and carbonated drinks. Susceptibility to erosion in primary dentition is more compared to permanent dentition due to softer and disordered crystal structure of enamel.

Objectives: The main aim of the study was to determine and compare the erosive potential of different fruit juices in frozen/unfrozen forms on primary teeth by studying the calcium dissolution.

Materials And Methods: pH of four different juices (pure) - apple, orange, citrus limetta (musumbi) and grapes were determined using a digital pH meter. The titratable acidity of these in frozen and unfrozen forms were determined by adding 0.2 ml of 1M NaOH to these to raise to pH=5.5(critical pH) and pH =7(neutral pH). Forty eight caries free deciduous anterior teeth specimens were prepared to study the calcium dissolution by atomic absorption spectrophotometer. The results were analysed for statistical significance using One-way Repeated Measures ANOVA and pair wise multiple comparison with Bonferroni correction.

Results: Total titratable acidity and calcium dissolution were found to be significantly more in the initial thawed fruit juices.

Conclusion: Frozen fruit juices had more buffering capacity and erosive potential than unfrozen forms. The study concluded that sucking on frozen fruit juices is more damaging to teeth than unfrozen forms because more of erosion is expected to occur in a frozen state.

Levels of Mercury in Fish-Eating Children, With and Without Amalgam Restoration.

J Pharm Bioallied Sci 2019 May;11(Suppl 2):S397-S401

Department of Oral Pathology, Faculty of Dentistry, Asian Institute of Medicine, Science and Technology (AIMST) University, Kedah, Malaysia.

Background: Mercury is a naturally occurring metal that exists in three forms: elemental (metallic), inorganic, and organic mercury. Amalgam, which is an alloy of inorganic mercury, is used as a restorative material in dentistry. Organic mercury gets ingested in the body mainly by the consumption of seafood. Mercury is also stated to cause various adverse health effects such as gastrointestinal disturbances, dermatitis, muscle weakness, and neurological disorders. In recent years, the use of amalgam has become a controversy stating the various adverse effects of mercury. Hence, the study was conducted to determine and compare the variation in levels of organic and inorganic mercury in fish-eating children before and after placement of amalgam restoration.

Materials And Methods: Seventy-five subjects, 42 males (56%) and 35 females (44%) of age group ranging 7-13 years, living in South Canara district of Karnataka, India, were selected as a part of the study. Hair and urine samples were collected for estimation of organic and inorganic levels of mercury, respectively. Informed consent was collected from all the participating subjects.

Results: On comparison between organic and inorganic mercury levels during the study period, the concentration of organic mercury in hair samples was greater irrespective of amalgam restorations present (1.172 and 0.085, respectively; < 0.001).

Conclusion: Thus inorganic levels of mercury do not seem to pose a threat as much as the organic levels observed in hair, which remain fairly constant for a longer period of time. Hence in a coastal region where this study was undertaken and fish being a staple food, the risk could probably be attributed to more of an organic toxicity than an inorganic one. Thus amalgam is relatively safe to be practiced and the controversy against it should be reevaluated.

Endodontic Management of a Severely Dilacerated Mandibular Third Molar: Case Report and Clinical Considerations.

Case Rep Dent 2018 8;2018:7594147. Epub 2018 Oct 8.

Department of Oral Pathology, Faculty of Dentistry, Asian Institute of Medicine, Science and Technology (AIMST) University, Kedah, Malaysia.

This article aims at providing an insight to the clinical modifications required for the endodontic management of severely dilacerated mandibular third molar. A 35-year-old patient was referred for the root canal treatment of the mandibular left third molar. An intraoral periapical radiograph revealed a severe curvature in both the canals. A wide trapezoidal access was prepared following the use of intermediate-sized files for apical preparation. Owing to increased flexibility, Hero Shaper NITI files were used for the biomechanical preparation and single cone obturation was carried out. Third molars owing to their most posterior location-limited access coupled with a severe curvature pose utmost clinical challenges require meticulous skill, advanced technology, and patience to achieve success.

Ameloblastic Fibroodontoma: Uncommon Case Presentation in a 6-Year-Old Child with Review of the Literature.

Case Rep Med 2017 13;2017:9483738. Epub 2017 Aug 13.

Department of Oral Pathology, Faculty of Dentistry, Asian Institute of Medicine, Science & Technology (AIMST) University, Kedah Darul Aman, Malaysia.

Ameloblastic fibroodontoma is a benign mixed odontogenic neoplasm considered in patients with asymptomatic swelling and unerupted teeth that exhibit histologic features between ameloblastic fibroma and complex odontoma. Radiographically, this lesion appears as radiolucency admixed with focal radio opaque masses of irregular shapes and sizes. This lesion is confirmed by the presence of proliferating odontogenic epithelium, ectomesenchyme, and dental hard tissue formation on pathological analysis supplementing clinical and radiographic findings. As this tumour is less commonly seen in routine clinical practice, ameloblastic fibroodontoma with detailed orofacial features and periodic approach to its diagnosis is discussed. This paper reports a case of ameloblastic fibroodontoma of the mandible in a 6-year-old male patient with an uncommon case presentation and review of the literature.

"Ormocer an innovative technology": A replacement for conventional cements and veneer? A comparative analysis.

Eur J Dent 2017 Jan-Mar;11(1):58-63

Department of Oral Pathology, AIMST University, Kedah, Malaysia.

Objective: This study was designed to assess shear bond strength (SBS) of ormocer flowable (OF) resin as a luting agent, ormocer as an indirect veneer material with portrayal of modes of failures using scanning electron microscope (SEM).

Materials And Methods: Sixty maxillary central incisors were divided into Group I, II, and III with 20 samples each based on luting cement used. They were OF, self-adhesive (SA) cement, and total etch (TE) cement. These groups were subdivided into "a" and "b" of ten each based on the type of veneering materials used. Veneer discs were fabricated using Ormocer restorative (O) and pressable ceramic (C). Specimens were thermocycled and loaded under universal testing machine for SBS. The statistical analysis was done using one-way ANOVA Tukey honest significant difference method.

Results: A significant difference was observed between the Groups I and II ( < 0.05). The highest mean bond strength when using ormocer veneer was obtained with the Group Ia (19.11 ± 1.92 Mpa) and lowest by Group IIa (8.1 ± 1.04 Mpa), whereas the highest mean bond strength while using ceramic veneer was of similar range for Group Ib (18.04 ± 4.08 Mpa) and Group IIIb (18.07 ± 1.40 Mpa). SEM analysis revealed OF and TE presented mixed type of failure when compared with SA where failure mode was totally adhesive.

Conclusion: OF was found equally efficient like TE. Bond strength of ormocer as a veneer was not inferior to ceramic making it one of the promising additions in the field of dentistry.

Unusual Presentation of Primary Squamous Cell Carcinoma of Mandible.

Case Rep Pathol 2016 19;2016:9154309. Epub 2016 Dec 19.

Department of Oral Medicine & Radiology, Karpaga Vinayaga College of Dental Sciences, Chennai, India.

Carcinoma arising primarily from the jaw is a locally aggressive lesion with poor prognosis. Primary intraosseous carcinoma (PIOC) lesion develops either de novo remnants of odontogenic epithelium, odontogenic cyst/tumor, epithelium remnants, or/and salivary gland residues. We describe very interesting case of primary intraosseous carcinoma of mandible. This extensive lesion was sent for oncological opinion and further management. Due to the uncertainty of diagnostic criteria of PIOC, only few cases of this lesion with a typical presentation have been reported. This article presents a case of primary intraosseous carcinoma with a unique appearance and detailed review stating its clinicopathological correlation.

Effect of anti-asthmatic drugs on dental health: A comparative study.

J Pharm Bioallied Sci 2016 Oct;8(Suppl 1):S77-S80

Department of Pediatrics, Sree Mookambika Institute of Medical Sciences, Kanyakumari, Tamil Nadu, India.

Aims: Bronchial asthma constitutes important problem worldwide. This chronic lung disease has detrimental effect in the oral cavity like reduction of salivary secretion, change in salivary composition and pH.

Materials And Methods: This study was conducted to compare the prevalence of dental caries in asthmatic children and healthy children, and also to evaluate the correlation between the , and dental caries in both the groups.

Results: In this study, the mean decayed, missing, filled teeth score of children in the study group was (4.53 ± 3.38) higher than the control group (1.51 ± 1.58) ( < 0.01). The count of the study group was (59574.47 ± 28510.67) higher than the control group (19777.78 ± 17899.83) < 0.01. The count in study group was (43553.19 ± 58776.96) higher than the control group (8843.84 ± 7982.72) < 0.01. Subjects using inhaled corticosteroids were more prone to develop dental caries than the control group with odds ratio = 6.26 and 95% confidence interval.

Conclusions: The dental caries prevalence increases with the usage of β agonist and corticosteroid inhalers for the treatment of asthma. Thus in asthmatic children, increase in caries prevalence might be due to the drug treatment and not due to the disease by itself. It can be concluded that asthmatic children have a higher prevalence of dental caries than healthy children. Hence, special oral health care is needed for asthmatic children.

Traumatic ulcerative granuloma with stromal eosinophilia - Mystery of pathogenesis revisited.

J Pharm Bioallied Sci 2015 Aug;7(Suppl 2):S420-3

Private Dental Practitioner, Sree Sai Dental Care, Kolapakkam, Chennai, Tamil Nadu, India.

Oral ulcers are a common symptom in clinical practice. Among various causative factors, different types of ulcers in oral cavity exist. Among this, traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) appears to be quite neglected by the clinicians due to the limited knowledge and awareness. On reviewing with a detailed approach to titles and abstracts of articles eliminating duplicates, 40 relevant articles were considered. Randomized studies, review articles, case reports and abstracts were included while conference papers and posters were excluded. Of importance, TUGSE cases been reported only to a minimal extent in the literature. Lack of its awareness tends to lead clinicians to a misconception of cancer. Thus, this particular lesion needs to be differentiated from other malignant lesions to provide a proper mode of treatment. The present article reviews various aspects of the TUGSE with emphasis on the clinical manifestation, pathogenesis, histological, and immunohistochemical study. This study provides the clinician contemporaries, a humble expansion to their knowledge of the disease, based on the searched literature, enabling a more comprehensive management of this rare occurrence.
