Introduction: Various aetiological factors for Early Childhood Caries (ECC) have been suggested in literature, but the role of each factor has been disputed in various studies. Aim: To evaluate the association between ECC and its related factors in children between three to six years of age, from rural, semi-urban and urban schools in the district of Salem (India). Materials and Methods: The study consisted of children between three to six years of age, selected randomly from schools in semi-urban, urban and rural schools at Salem. Questionnaire (comprising of the factors associated with ECC) and parental consent forms were sent to each of the parents of the school children. Filled questionnaires and parental consent forms were obtained from a total of 2771 children, out of which 1771 were boys and 1000 were girls. Clinical examination for ECC was carried out according to the WHO criteria, by a single examiner and an assistant to eliminate inter-examiner variability. Statistical analysis was carried out using the student’s independent t-test and ANOVA (one way analysis of variance). Results: Out of a total of 2771 children examined, only 443 (315 boys and 128 girls) children were found to have ECC (16 %). Significant correlations were found between the occurrence of ECC and various factors like age of parents, number of siblings, on-demand breast feeding and bottle feeding habits and sweetened pacifier use. However, factors such as age and gender of the child, type of birth and duration of pregnancy, had no significant correlation with the occurrence of ECC. Conclusion: The need for educating parents on the ill effects of improper breast feeding and bottle feeding habits is important. © 2017, Journal of Clinical and Diagnostic Research.

Aim: To find the incidence of different types of lip patterns, the dominant pattern, quadrant wise, amongst the Goan population. To assess, the quadrant wise differences in lip patterns among males and females and to report new lip print pattern in Goan population. Methodology: Lip prints of 100 students studying in Goa Dental College & Hospital were taken using 14 mm wide and 50 mm long Scotch tape without any distortion. These prints were then scanned (256 gray shades at a resolution of 300 dpi.) for the digital analysis. Using various applications of Adobe Photoshop 7 software an attempt was made to trace each and every line. K. Suzuki and Y. Tsuchihashi's classification was followed to define the patterns of the grooves. Results: The current study has found the most predominant pattern in Quadrant I to be Type V (580 lines; 52.39%) followed in order by Type I′ (196 lines; 17.70%), Type I (166 lines; 14.99%), Type II (166 lines; 10.47%), Type IV (40 lines; 3.61%), Type III (9 lines; 0.81%). In Quadrant II of this study the most predominant pattern recorded was Type V (589 lines; 50.47%) followed in order by Type I′ (209 lines; 17.90%), Type I (204 lines; 17.48%), Type II (130 lines; 11.13%), Type IV (34 lines; 2.91%), Type III (1 line; 0.08%). In Quadrant III of this study the most predominant pattern recorded was again Type V (484 lines; 52.09%) followed in order by Type I′ (174 lines; 18.72%), Type I (155 lines; 16.68%), Type II (102 lines; 10.97%), Type IV (9 lines; 0.96%), Type III (5 lines; 0.53%). In Quadrant IV of this study the most predominant pattern recorded was Type V (543 lines; 58.19%) followed in order by Type I (151 lines; 16.18%), Type I′ (138 lines; 14.79%), Type II (85 lines; 9.11%), Type III (9 lines; 0.96%), Type IV (7 line; 0.75%). In all four Quadrants the most predominant pattern found in males and females was Type V. The present study recorded the following types of type V patterns for the first time; Trifurcations, Bridge or 'H' pattern, Horizontal Lines, Cartwheel, Pineapple Skin and Multiple Branching Appearance. Conclusion: The digital method of analyzing the Lip Print images using Adobe Photoshop 7 software serves as a convenient method that provides better visualization and ease in identification and recording of the Lip Print pattern. Predominant pattern in all four quadrants was Type V followed by the linear pattern i.e. Type I′ in quadrants I, II, and III and Type I in quadrant IV in the studied population. Distribution of pattern is not affected by the sex. Although type V is the most predominant pattern found in Goan population, the sub-classification of this type defines the more defined term and aids in accuracy of the classification. © 2012 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Ceramics have a long history in fixed prosthodontics of achieving optimal esthetics. Yttrium tetragonal zirconia polycrystal (Y-TZP)-based systems are a recent addition to the high-strength, all-ceramic systems used for crowns and fixed partial dentures. CAD/CAM-produced, Y-TZP-based systems are in considerable demand in esthetic and stress-bearing regions. The highly esthetic nature of zirconia coupled with its superior physical properties and biocompatibility have resulted in restorative systems that meet the demands of today's patients. Undoubtedly, these systems are considered to be prospective replacements for metal-ceramic restorations. This article reviews relevant contemporary literature regarding all-ceramic materials and systems and discusses their material properties, biocompatibility, advances in cementation, and more with special emphasis on clinical survival. The article also aims to provide recommendations for their use.

Objective: This article focuses on understanding our older patients who require complete prosthodontic care. By breaking down the patient psychology to its component parts, it is easier to obtain a clear picture of this special cohort of patients. Considering the increase in number of geriatric edentulous patients, this knowledge will help the dentist serve the geriatric population better. Background: The role of psychology and personality in complete denture treatment is well documented. The geriatric patient who needs complete dentures has a psychological aspect that needs consideration. Although significant, these aspects may sometimes be ignored or considered irrelevant. Materials and methods: A review of relevant literature was carried out to obtain data on the psychology and personality of geriatric, complete denture patients and their behavioural changes. The obtained data was filtered and condensed to provide a short but comprehensive look at the geriatric edentulous patient's psychology. Conclusion: When handling geriatric edentulous patients, the dentist must be confident of addressing and managing the psychology of these patients. A thorough understanding of the geriatric mental state thus becomes important and significant for the clinician. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Aim: To report the non-surgical management of a large periapical lesion. Summary: Surgical treatment of large periapical lesions is often subject to various complications. Hence, a non-surgical approach should be considered for the management of these lesions. The traditional aspiration technique involves creation of buccal and palatal wounds that can cause considerable discomfort for the patient. This case report describes a simple aspiration technique achieved through the root canal space, which might hasten osseous regeneration, whilst eliminating the need for periapical surgery. Key learning points: • Non-surgical techniques can aid in healing of periapical lesions.• Non-surgical approaches should be considered before resorting to surgery. © 2010 International Endodontic Journal.

The palatine rugae possess unique characteristics that could be used when it is difficult to identify a dead person according to fingerprints or dental records. They are permanent and unique to each person. The rugae are surrounded by cheeks, lips, tongue, and buccal pad of fat; hence, they remain protected in trauma, incineration, or mass disasters. Their pattern of orientation is formed by the 12th to 14th week of gestation and remains stable throughout life. In this study, dental casts of 120 patients were analyzed for individual rugae characteristics and strength and subsequent individual codes were given. No two individuals were having exactly matching rugae codes. Dimensions of rugae pattern, incisive papilla, and midpalatal raphe were also noted. Rugae were reevaluated after one year to check its stability, which showed no significant difference. The coding system followed can be adopted as a good and simple technique to achieve electronic transfer of the records of the palatal rugae. © 2013 American Academy of Forensic Sciences.

Removable partial denture is a repulsive modality of treatment that we still must rely upon for certain cases and is a part of the practice. But these patients expect it to look as esthetic as any other contemporary modality of treatment. This article thus focuses on the esthetic aspects that a clinician must place emphasis upon during the designing and fabrication of prosthesis to provide the desirable outcome.

Objectives: Both periodontitis and osteoporosis represent major health problems especially in elderly women. The relationship between the two diseases and oral bone loss is important having significant public health impact in the prevention of morbidity and mortality related to these disorders. The present study was aimed to investigate the possible association between osteoporosis and periodontal disease among postmenopausal women residing in Goa, India. Study design: A complete periodontal examination (all teeth except third molar) including plaque index (PI), gingival index (GI), clinical attachment loss (CAL) measurement was performed on 80 dentate Goan postmenopausal women (age ≥ 50 yrs) with generalized chronic periodontitis. Mean alveolar bone loss (ABL) was measured from full mouth intraoral periapical radiographs, by recording the distance from cementoenamel junction (CEJ) and the most coronal portion of alveolar crest at mesial and distal aspect of all teeth except canines and third molars. Systemic bone loss was determined from hand-wrist radiograph of the patient through Digital X-Ray Radiogrammetry. Statistical analysis was done to assess the relationships between peri-odontal variables and bone mineral density (BMD) after adjusting for age, years since menopause, body mass index (BMI), smoking, number of remaining teeth, PI and GI. Results: Age of the patient, years since menopause and BMI showed significant correlation with BMD. CAL and ABL showed mildly negative and statistically non-significant correlation with the BMD. Of all the variables studied, only smoking and BMI were strong predictors of BMD. Conclusion: Skeletal BMD is related to interproximal ABL and CAL, though not to a statistically significant level; implicating postmenopausal osteopenia as a risk indicator for periodontal disease. © Medicina Oral S.

Reattachment of the fractured fragment of a traumatized tooth (whenever available and usable) has become the treatment of choice in cases of uncomplicated crown fractures. Despite the presence of various bonding materials and techniques, laboratory data evaluating the biomechanical aspects of such procedures is largely lacking in the literature. The objective of this in vitro study was to evaluate the fracture strength recovery of incisors, following fragment restoration with three different techniques. A total of 90 extracted human maxillary central incisors were subjected to crown fractured under standard conditions. This was carried out by applying a compressive force from the buccal aspect of the clinical crown using a universal strength testing machine. The fractured teeth were equality distributed in three groups, defined on the basis of the technique used for reattachment: i) overcontour, ii) internal dentinal groove and iii) direct buildup. Each group was further subdivided into three subgroups on the basis of the intermediate restorative material used for reattachment, namely: i) hybrid composite (Filtek Z100 Universal Restorative, ii) nanocomposite (Filtek Z350) and iii) Ormocer (Voco Admira). Following reattachment, the crowns were re-fractured under standard conditions. The force required for fracture was recorded and was expressed as a percentage of the fracture strength of the intact tooth. The data was expressed as a percentage of the fracture strength of the intact tooth. The data was analyzed using two-way ANOVA and Bonferroni tests for pair-wise comparison. The results showed no statistically significant differences in fractures strength between the three groups (P > 0.05). However, comparison of the subgroups revealed statistically significant higher strength recovery percentages for the hybrid and the nanocomposite compared with the Ormocer material (P < 0.05). It was concluded that material properties have a significant influence on the success of reattachment procedures.
