Oral health care is the foundation upon which preventive evaluation and dental care must be built to enhance the opportunity for life free of preventable and oral diseases. The purpose of the study was to determine the oral health care and disease prevention among the Tiruvannamalai population. Selfadministered questions were prepared. The questions were distributed in google forms, and 100 participants participated. The data was entered and statistically analysed. In this study, 88% maintain oral health as an integral part of our everyday practice. 65.1% maintain good oral health by using a toothbrush and paste, and 11% are lossing their teeth daily. 33% are cleaning the teeth to prevent dental disease. Within the limitations of the study, we can conclude that oral health knowledge among the Tiruvannamalai Population was considerably lower than what would be expected. Still, they showed a positive attitude toward oral healthcare.

To prepare and modify different wax compositions in order to find out the most suitable formula that has almost the same properties of dental modeling wax used in dentistry. Materials and Methods: Three groups of waxes (220 samples) with different compositions regarding its origin (Al-Dora refinery waxes, natural bees wax-North of Iraq, and commercially available Iraqi waxes), additives such as starch, sodium-carboxyl methylcellulose (Na-CMC), rosin, or nylon, and coloring agents were prepared. The samples were tested for their melting range, 21 samples only had a melting range that nearly coincides with that of the dental waxes such as Major and Cavex. Results: The resultant 21 samples were tested for their softening, trimming, penetration, residue materials and solubility. Only 4 samples showed properties that are closely similar to that of Major and Cavex wax. The results of melting point ranged from 69-80 o C. Softening test showed that the samples which contain nylon, Na-CMC, or rosin were softened without adhering to the fingers. Trimming test showed that they were trimmed easily and clearly. Penetration test showed that, some samples had the similar measurements of Major and Cavex wax (0.6-0.9mm). Residue materials showed that all samples had no residue of wax materials on acrylic teeth after wax elimination procedure. All the prepared waxes were soluble in ether (acetone), and petroleum spirit (benzene). Conclusion: Six new modeling wax materials were prepared according to ADA specification No.24. Three of new wax materials consist of nylon (polystyrene 1.71-2.13%); the other two novel modeling waxes were fabricated by using additive materials (Na-CMC and rosin).

Introduction: Root canal cleaning is the main objective of endodontic treatment and requires knowledge of the internal anatomy. The premolars are evidenced in the literature with great anatomical variations. In view of this, studies indicate that the use of Cone Beam Computed Tomography helps in the visualization of highly complex anatomy. Objective: to describe the anatomical variations in maxillary and mandibular premolars using cone beam computed tomography in a radiologic clinic in Piaui. Methods: 54 cone beam computed tomography scans with 160 premolars were used, produced using the Orthopantomograph OP300 equipment and analyzed by multiplanar reconstructions: axial, coronal and sagittal. Data regarding sex, number of roots and canals were recorded to compare and classify according to Vertucci. Results: the maxillary first pre-molars had 63.5% two roots,83.7% with one root and the mandibular pre-molars mostly with one root. Regarding the number of channels, 92.3% of the first premolars had two channels, most of them maxillary second premolars and mandibular premolars only one channel. Vertucci variations of types I, II, III and IV were verified in single-rooted elements, observing a great variation in superior elements. As for the prevalence of sex, only the first superiors showed greater variation in males. Conclusions: the upper first premolars prevailed with a great anatomical variation in relation to the other premolars with prevalence of Vertucci Type I and in males.

Tooth loss is quite common worldwide. For treating a lost tooth, treatments such as dental implants (most common worldwide), fillings (made up of inert dental material), dentures, etc. These techniques can restore all the functions of a normal tooth. But using dental tissues and other dental related materials are still a mystery to the dental world. Pubmed research revealed 117 relevant articles. Out of which a total of ‘33’ systematic reviews and their original citations were included in this review. Tooth regeneration is a very complicated process and needs more depth study on this topic. From many of the researches that were reviewed in this article it was seen that there were many new methods developed but none were approved for applying in real life. Tooth regeneration is a vast topic and requires a lot of knowledge to be understood. This study can be used as reference for future research. KEYWORD: Biomaterials, stem cells, tooth regeneration.

Aim: The present case report discusses the treatment of an endodontically treated mandibular molar tooth with three roots and four canals. Two canals were present in the mesial side and one each was present in the disto-buccal and disto-lingual side. Background: Mandibular molars may have an additional root which may be located buccally or lingually. When it is buccally located it is called as radix paramolaris and when lingually located it is termed as radix entomolaris (RE). Hence, the presence of such a pulpal system calls for challenges in providing endodontic treatment. Case description: A female child of 13 years age, reported to the Department of Pedodontics & Preventive Dentistry with a chief complaint of lancinating pain in the lower back region of the right side of the mandible. The pain was present for last two months. On clinical examination, the mandibular first molar of right side was deeply carious with tenderness on percussion. Intra oral periapical radiograph showed carious lesion involving enamel, dentin and pulp along with an extra root between the distal and mesial roots. To confirm that additional root is present, two intra oral periapical radiographs with different horizontal angulations were taken. After taking radiographs, an additional root was confirmed to be present on the disto-lingual side of the mesial root. Final diagnosis of irreversible pulpitis was made. The treatment modality planned was root canal treatment.

Aims and objectives: To evaluate the maxillary and mandibular morphology in different vertical facial types and to implicate the achieved results into diagnosis and treatment planning of patients requiring orthodontic treatment. The present study is conducted on a sample of 120 subjects comprising of 60 males and 60 females in the age range of 18 to 25 years. The lateral head cephalograms of the subjects were divided into three groups, i.e. group I (hypodivergent), group II (normodivergent) and group III (hyperdivergent) with regard to vertical facial type by using the following three parameters, i.e. SN-MP (facial divergence angle), overbite depth indicator (ODI) and Jarabak ratio or facial height ratio (FHR). Differences among the groups and between genders were assessed by means of variance analysis and Newman-Keuls post hoc test. Results: Maxillary and mandibular anterior alveolar and maxillary postalveolar height was found to be greater for hyperdivergent group in comparison to others. Hyperdivergent facial types posses long and narrow symphysis along with greater antegonial notch depth whereas hypodivergent showed an opposite tendency. Hyperdivergent facial types generally have a smaller maxillary area as compared to other facial types. However, total mandibular area does not vary among different vertical facial types. Sexual dichotomy was found with maxillary anterior alveolar and basal height, mandibular posterior alveolar and basal height, mandibular length, symphyseal depth, depth of the antegonial notch, symphyseal area and ext/total symphyseal area ratio. Vertical facial type may be related to the morphological and dentoalveolar pattern of both maxilla and mandible. Determination of this relationship may be of great help from diagnostic as well as therapeutic aspects of many vertical malocclusion problems.

The endodontic triad consists of cleaning and shaping, disinfection and obturation. Success of root canal therapy in primary teeth is mainly achieved by thorough removal of debris and necrotic tissue. However, complete elimination of bacterial contaminants as well as necrotic debris require adjunctive use of root canal irrigants along with mechanical instrumentation. As we know from literature that none of the available irrigating solutions alone provides all the ideal requirements. Studies have shown that a combination of two or more irrigating solutions in a specific sequence will help to achieve optimal irrigation. This review article mainly highlights the mechanism of action, safety and biocompatibility of currently used irrigation solutions and also the other materials that can be used as a potent irrigants, their advantages and limitations in future of endodontics.

Caries detection followed by its treatment had been an integral part of dentistry. Beside periodontal diseases, caries are also a chronic disease which causes tooth loose. Caries are dened as a multifactorial microbial infectious disease characterized by demineralization of inorganic and destruction of organic structure of the tooth. It is complex and dynamic process as it involves multiple factors that 1 inuence as well as initiate the progress of disease . Diagnosis is derived from Greek word dia which means ''through'' and gnosis which means ''knowledge''. Diagnosis can sometimes be a complicated procedure as it involve more than just detecting lesions.

The aim of endodontic therapy is the debridement of all vital or necrotic tissue, microorganisms, and their products from the root canal system. This may be accomplished by chemomechanical debridement of root canal. However, irregular and oval canalcross-sections, accessory canals, isthmuses, fins, curves and apical delta make chemomechanical debridement difficult. Thus irrigation of root canal system becomes very essential. Various irrigants and irrigation systems have been introduced. This review article features the newer advances in irrigation systemsfor better debridement of complex root canal system.

Objective To compare the effectiveness of the XP-endo Finisher instrument and passive ultrasonic irrigation (PUI) as final irrigation protocols on the removal of accumulated hard-tissue debris (AHTD) from oval-shaped canals using micro-computed tomographic (micro-CT) analysis. Methods Twenty mandibular incisors were anatomically pair-matched based on similar morphological dimensions (length, volume, aspect ratio, and configuration) through micro-CT analysis, prepared with Reciproc R25 instrument, scanned again, and assigned to one of the two experimental groups (n = 10), according to the final irrigation protocol: XP-endo Finisher and PUI. After the final irrigation protocols, the specimens were rescanned and the registered datasets were examined to quantify the amount of AHTD. Data were statistically analyzed using Student's t test with a significance level of 5%. The final irrigation protocols were highly similar in terms of volumetric percentage reduction of AHTD (P = 1.000). Conclusions XP-endo Finisher and PUI showed the same effectiveness on the removal of AHTD. None of the tested final irrigation protocols completely removed the AHTD from oval-shaped root canals. Clinical relevance AHTD may be considered clinically relevant because it could harbor bacterial contents away from the disinfection procedures. Both final irrigation protocols were effective on the removal of AHTD.

Devising new approaches to hasten the regenerative process, thereby, waning the duration of wound healing persists to be one of prime goals of clinical research. Platelets play a crucial role in these regenerative procedures, as they act as reservoirs of cytokines and growth factors. A significant component of the orthodontic tooth movement encompasses a similar process as it essentially involves bone remodeling comprising of alternate cycles of bone resorption and deposition. The past decades have witnessed various attempts to accelerate the rate of orthodontic movement by versatile techniques leading to a decrease in the treatment time, a highly desired outcome by the patient as well as the orthodontist. The following review attempts to summarize existing literature concerning the application of platelet derived concentrates in dentistry and their potential role in orthodontics. The most commonly used platelet derived concentrates i.e Platelet Rich Plasma (PRP), Plasma rich in growth factors (PRGF) and the Platelet rich Fibrin (PRF) have been described and compared to aid in future opportunities of clinical research.

Resultados y discusión: El tratamiento de la avulsión dentaria se fundamenta en el reimplante del diente en su alveolo y posterior ferulización. Su pronóstico depende fundamentalmente del estado de las células del ligamento periodontal en el momento de la reimplantación, así como del tratamiento pulpar que se realiza con posterioridad. Existen discrepancias entre diferentes autores en cuanto al medio más apropiado para la conservación del diente. Conclusiones: El protocolo de actuación determina el éxito del tratamiento. Se recomienda que trascurra el menor tiempo posible desde el lugar del accidente hasta la consulta dental así como un adecuado medio de conservación del diente. Palabras clave: avulsed tooth, avulsion in pediatric dentistry and replantation.

The study aims to assess and contrast the compressive strengths of three aesthetically pleasing restorative materials. Materials and Methods: Using metallic molds, 30 pellets were created, then split into 3 groups of 10, each meeting the required specifications. Glass Ionomer Cement (GIC) cylindrical specimens are in Group A; Resin Modified GIC (RMGIC) cylindrical specimens are in Group B; and Zirconomer cylindrical specimens are in Group C. A universal testing equipment was used to compress all of the samples, and the results were acquired. Tukey's post hoc test and one-way ANOVA were used for statistical analysis. Result: Zirconomer's compressive strength is significantly higher than that of RMGIC and GIC. Conclusion: The compressive strength of Zirconomer is the highest. As a result, Zirconomer may be the preferred material for aesthetic restorative procedures.

AimTo introduce a new method to select anatomically matched teeth using micro‐computed tomographic (micro‐CT) technology.MethodologySingle‐rooted mandibular incisors with a single root canal (n = 60) were selected and distributed into three experimental groups according to the method used for matching 10 pairs of teeth in each group. In group 1, the pairs of mandibular incisors were randomly selected from a pool of teeth. In group 2, teeth were paired based on the measurement of canal width 5 mm from the root apex using radiographs taken from buccolingual and mesiodistal directions. In group 3, teeth were scanned (pixel size of 14.25 μm) and pair‐matched based on the anatomical aspects of the root canal, named aspect ratio (AR), volume and three‐dimensional canal geometry. After allocating the specimens into groups 1 and 2, the teeth were scanned and the canal morphology evaluated as in group 3. A bivariate Pearson’s regression analysis was performed correlating the individual AR va...

AimTo investigate the prevalence, location and pattern of pre‐existing microcracks in non‐endodontically treated teeth from fresh cadavers. Micro‐computed tomography (micro‐CT) technology was used as the analytical tool enabling full screening of the root dentine with the teeth retained in their original alveolar socket.MethodologyAs a pilot study and to validate the present method, a series of 4 high‐resolution scans were performed on one bone‐block specimen with teeth collected post‐mortem: (i) entire bone‐block including the teeth, (ii) second molar tooth extracted atraumatically from the bone‐block, (iii) extracted tooth dehydrated to induce dentinal defects and (iv) entire bone‐block following reinsertion of the extracted tooth into its matching alveolar socket. In the main study, forty‐two dentoalveolar maxillary and mandibular bone‐blocks each containing 3–5 adjacent teeth (a total of 178 teeth) were collected post‐mortem and scanned in a micro‐CT device. All cross‐section im...

AimTo investigate a potential cause–effect relationship between dentinal microcracks and fracture resistance of mandibular incisors that had not been endodontically treated.MethodologySixty mandibular incisors with circular‐shaped canals were selected based on micro‐computed tomographic scans to create a homogeneous sample. The cross‐sectional images of the specimens were screened to identify and quantify the presence of dentinal microcracks. Then, teeth were embedded in polystyrene resin and subjected to axial compressive loading using a universal testing machine. After fracture, the roots were re‐scanned and fractography analysis was performed by inspection of 3D models to verify crack propagation. Spearman’s rank correlation was used to assess the correlation between the number of microcracks and force required to fracture.ResultsDentinal microcracks were detected in 79% of the specimens (n = 44). The incidence of microcracks varied between teeth from 6% to 42% of the total slice...

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in developed countries. This disease is characterized by irreversible airflow limitation, increased pulmonary resistance, and hyperinflation of the lung. Clearly established risk factors for the pathogenesis of COPD are cigarette smoking and severe alpha 1-antitrypsin deficiency (SERPINA1). However, clustering of COPD within families without deficiency of SERPINA1 and individual variation in susceptibility to cigarette smoking suggests that additional risk factors, possibly genetic factors, contribute to the development of COPD. A variety of association studies have compared the distribution of variants in candidate genes that were hypothesized to be involved in the development of COPD, these variations include TNF, LTA, IL1B, IL4, IL10, and IL13 gene polymorphisms. Concerning HLA region, despite the contribution of this to several diseases, the role of HLA alleles in the pathogenesis of COPD ...

Laser therapy, grounded in optical biophysics, is a versatile, non-invasive medical treatment. This review explores its biophysical mechanisms, including photothermal, photomechanical, photochemical, and photobiomodulatory effects, which drive applications in surgery, dermatology, pain management, oncology, and ophthalmology. Techniques such as photodynamic therapy (PDT) and laserinduced hyperthermia enable precise cancer treatment, while LASIK and photocoagulation provide effective ophthalmologic solutions. Low-level laser therapy (LLLT) supports pain management and tissue regeneration. Despite its benefits, challenges include high costs, specialized training requirements, and treatment variability. Advancements in nanotechnology and artificial intelligence are expected to enhance laser therapy's precision and clinical impact in the future.

Background: Geospatial techniques are critical for identifying potential environmental risk factors and implementing effective prevention strategies for chronic diseases. The Mysuru stUdies of Determinants of Health in Rural Adults (MUDHRA)-Cohort was a notable study that systematically investigated the prevalence and risk factors associated with Chronic Bronchitis (CB) in 16 randomly selected villages of Mysuru District between 2006 and 2009. The objective of this study is to spatially visualize the highest prevalence of MUDHRA-CB at village level, and identifying potential environmental risk factors. Methods: An analysis was conducted on a total of 8457 individuals aged 30 years and older to ascertain the presence of chronic bronchitis symptoms. To assess the prevalence of chronic bronchitis, a door-to-door survey was conducted using international Burden of Obstructive Lung Disease (BOLD) study questionnaires. The thematic map of chronic bronchitis burden was generated using Geographic Information System (GIS) tools and overlaid on the land use and land cover patterns extracted from Remote Sensing (RS) satellite images. Results: The thematic map identified Karya village has having the highest prevalence (14.82 %), while there were no reported cases of chronic bronchitis in Alatthuru village. The land use land cover map generated showed the presence of a mine located around 310 m from Karya village. Inhalation of dust particles from the mine operations and wind direction could be attributed to the higher prevalence of chronic bronchitis. Conclusion: Spatial epidemiological research studies that incorporate RS, GIS, and local field studies may aid in identifying potential environmental factors associated with a higher risk of chronic conditions.
