Reason for tooth material loss among FMR patients - A retrospective study

Tooth wear is a general term describing the loss of dental hard tissues, from the surface of the teeth caused by factors other than dental caries, trauma and developmental disorders. Attrition, Abrasion and erosion usually cause alterations of the tooth surfaces and manifest as tooth wear. Tooth surface loss may be considered physiological or pathological. Physiological tooth surface loss occurs as a result of mastication and adjustment, which is required for the teeth to function correctly. Physiological tooth surface loss may also occur at interproximal tooth surfaces due to friction between the adjacent teeth. Inversely, pathological tooth surface loss represents unacceptable levels of dental hard tissue loss. It is characterized by abnormal destruction, which may require treatment. The aim was to assess the reason for tooth material loss among FMR diagnosis patients. A retrospective study sample of 65 cases was collected from DIAS(Dental Information Archiving Software). The data was converted into an excel sheet for tabulation and further statistical analysis were done in SPSS. The p-value was insignificant and the current study proves that the reason for tooth material loss is predominantly caused by attrition. Within the limits of the study, the reason for tooth material loss is due to attrition.

Prevalence of Attrition, Abrasion, Erosion and Abfraction Among Patients Visiting A Private College Hospital in Chennai - A Retrospective Study

Regressive changes of the teeth include a variety of alterations in the dental tissues, mechanical tear andwear of tooth is a consequence of both pathological and physiological means. Tooth surface loss can beclassified primarily as attrition, abrasion, abfraction and erosion. To assess the prevalence of attrition,abrasion, erosion and abfraction among patients visiting private college hospital in Chennai. Data of thepatients retrieved was from the dental records of the hospital. Patients with attrition, abrasion, erosionand abfraction were shortlisted. Total study sample, n=7300 patients. Data was tabulated in excel andstatistically analysed. From the statistical analysis, it was significant that the most prevalent type of toothwear was attrition(49.7%), followed by abrasion(48.3%), erosion(1%) and abfraction(0.97%) (chi squaretest- p-value= 0.000- significant). Within the limitations of this study, it showed that there was a significantprevalence of attrition followed by abrasion, erosion and abfraction with a male predilection, predominantlybetween the age group of 41-60 years, reported to private college hospital in Chennai.

Determining dental students’ and dental hygiene students’ perceptions of eating disorders and their management

##Statement of the problem Pathological tooth surface loss (TSL) is an increasing challenge for dental healthcare professionals (DHCPs). Patients with eating disorders (EDs) may present with TSL and future DHCPs should be aware of the medical, dental and general management of patients with EDs who may present with TSL. ##Purpose of the study Determine perceptions of undergraduate students at Cork University Dental School and Hospital (CUDSH) regarding their training and the management of eating disorders. ##Methods A questionnaire was distributed to final year dental (FYD; n=47) and dental hygiene (FYDH;n=14) students approaching the end of their studies at University College Cork. ##Results A response rate of 40% for FYD (n=19) and 86% for FYDH (n=12) students showed no obvious trends differentiating between perceptions of FYDs and FYDHs. The perceived confidence of students in managing patients with EDs varied widely. A number of respondents perceived inadequate training in relation to oral manifestations (32%) and dental management (16%) of patients with EDs. In relation to the medical management (90%), personality traits (71%) and psychological needs (81%), students perceived a requirement for further training. A total of 77% of respondents were unaware of local support services available to ED patients, with 94% also unaware of Eating Disorder Centre Cork (EDCC). ##Conclusion There is a need for improvement within the dental curricula in education regarding patients with EDs, specifically their comprehensive management by DHCPs and surrounding services.

Knowledge and Awareness Regarding Bruxism and its Management in Dakshina Kannada Population

Bruxism is defined as a ‘repetitive jaw-muscle activity characterized by clenching or grinding of the teeth and/or by bracing or thrusting of the mandible’ with ‘two distinct circadian manifestations; either occurring during sleep (sleep bruxism) or during wakefulness (awake bruxism).’ Bruxism may lead to masticatory muscle hypertrophy, tooth surface loss, fracture of restorations or teeth, hypersensitive or painful teeth and loss of periodontal support. A sample of 100 patients were selected for a questionnaire study to assess the knowledge ad awareness regarding bruxism and its management. The results showed that there was an overall lack of awareness in the population. Knowledge and awareness should thus be provided to the population to ascertain early treatment and less discomfort to the patients having signs and symptoms of bruxism.

Impact of Tooth Surface Loss on the Quality of Life of Patients Seen in a Nigerian Teaching Hospital

Background: Tooth surface loss (TSL) is a progressive process arising from erosion, abrasion, attrition or abfraction. It can affect individuals of any age group: children, young adult, adults or the elderly and can compromise the health of individual tooth or the entire dentition leading to poor quality of life of the affected person. Objective: To evaluate the pattern of TSL among dental patients in a Nigerian Teaching Hospital and to assess the impact of TSL on their quality of life. Subjects and Methods: The study was a cross-sectional study among patients with TSL in a Nigerian Teaching Hospital. The Oral Health Impact Profile-14 (OHIP-14) questionnaire was used to obtain information on the impact of TSL on the quality of life of the participants. Data collected were analysed using IBM SPSS version 20. Chi-square test was used to assess association between types of TSL and quality of life of the patients. Level of significance was set at p ≤ 0.05. Results: One hundred and twenty-five patients (Males = 72; Females = 53) with tooth wear lesions participated in the study. The most common type of tooth surface loss was attrition (40%) followed by abrasion (23.2%). The highest impact of TSL on the quality of life was painful sensation strongly affecting 39 (31.2%) patients. This was followed by problem with chewing. There was no statistically significant relationship between patients’ quality of life and types of tooth surface loss. Conclusion: The most common negative impact of TSL on patient quality of life was painful sensation.

Comparative Effect of Calcium Mesoporous Silica Versus Calcium and/or Fluoride Products on the Reduction of Erosive Tooth Wear and Abrasive Enamel Lesion

Objective: To evaluate the effect of a calcium nanocompound on the reduction of erosive tooth wear and abrasion. Material and Methods: Bovine enamel specimens (BE), were randomly assigned to the following groups (n = 10): G1 = Calcium mesoporous silica nanoparticles (Ca 2+ MSNs); G2 = casein phosphopeptide-amorphous calcium phosphate (CPP-ACP, 2% CPP-ACP, GC ® ); G3 = casein phosphopeptide-amorphous calcium fluoride phosphate (CPP-ACFP, 2% CPP-ACP + 900 ppm F - , GC ® ); G4 = sodium fluoride NaF (900 ppm F-, positive control); and G5 = distilled and deionized water (negative control). Each product was applied to the exposed area for one minute, three times per day for three consecutive days, and followed by the immersion of the specimens in Sprite Zero™ - a low-pH solution (2.58) for five minutes (Coca-Cola™). After the first and last erosive challenges of the day, the specimens were submitted to abrasion in a toothbrush machine for 15 seconds (200 g/BE). The specimens were analysed using 3D non-contact optical profilometry, with tooth structure loss (TSL) measurements and scanning electron microscopy (SEM). TSL values were analysed by Kruskal-Wallis and Mann-Whitney tests (p<0.05) . Results: There were no significant differences between G1 (10.95 µm) and G3 (10.80 µm) treatments for TSL values; however both resulted in significantly reduced TSL values compared with the G5 (16.00 µm) (p<0.05). The G4 (12.26 µm) showed no statistically significant difference when compared to the G5 (16.00 µm). The groups G1 and G3 presented higher surface preservation than the G5 . Conclusion: Ca 2+ MSNs was effective for reducing tooth surface loss caused by erosive tooth wear and abrasion.

This article has no abstract. The first 100 words appear below: A 22-year-old male reported to the outpatient department with the complaints of occasional pain and tingling sensation on his maxillary left posterior teeth and mandibular anterior teeth for 3 to 4 months with slight mobility of mandibular anterior teeth. He had no significant medical history as well as no history of trauma and familial history of similar disease. He also stated that he went to Dhaka Dental College where he received clinical and radiological investigations and diagnosed as a case of external tooth resorption. In the Dhaka Dental College, upper left 1st and 2nd premolar, mandibular right central and lateral incisor teeth were extracted.

A Conservative Approach to Treatment of Dental Erosion: Case Report

Tooth surface loss is a common condition with nearly three-quarter of the population in Trinidad & Tobago exhibiting signs and about one-fifth of those persons have moderate or severe wear. These patients become difficult to treat due mainly to loss of clinical crown height and also loss of occlusal vertical dimension. This case depicts the use of a conservative approach to treating a patient with moderate tooth surface loss, as assessed via the tooth wear index, with aetiology of acid erosion. The poor appearance of the dentition was the patient’s chief presenting complaint. With the use of 3M Filtek™ Z 250 Universal Restorative Composite (St Paul, MN, USA), temporary posterior build-ups were placed to increase the patient’s Occlusal Vertical Dimension (OVD) and were subsequently replaced with metal onlays. Anterior composite veneers were placed to achieve an aesthetically pleasing result at the increased OVD. The combined use of composite and metal onlays allowed for an economical and more conservative treatment modality for dental erosion rather than full coverage posterior and anterior crowns.

Sleep bruxism: an overview for clinicians

Bruxism is characterised by clenching or grinding of the teeth due to contraction of the masseter, temporalis and other jaw muscles. Bruxism may lead to masticatory muscle hypertrophy, tooth surface loss, fracture of restorations or teeth, hypersensitive or painful teeth and loss of periodontal support. Sleep bruxism has previously been viewed as a dysfunctional movement or pathological condition, whereas it is now accepted as a centrally controlled condition with various systemic risk factors. It has been postulated that sleep bruxism may have a protective role during sleep, for example in relation to airway maintenance or in stimulating saliva flow. A diagnosis of sleep bruxism may be made via patient report and clinical interview, clinical examination, intraoral appliances or recording of muscle activity. Bruxism in itself does not require treatment: management is only indicated where problems arise as a result of bruxism. Oral appliances primarily aim to protect the dentition from damage caused by clenching/grinding, although they may reduce muscle activity. Irreversible occlusal adjustments have no basis in evidence in the management of bruxism. Behavioural strategies include biofeedback, relaxation and improvement of sleep hygiene. Administration of botulinum toxin (Botox) to the masticatory muscles appears to reduce the frequency of bruxism, but concerns have been raised regarding possible adverse effects. Dentists should be aware of the potential aetiology, pathophysiology and management strategies of sleep bruxism.

Complications in managing tooth wear; exploring a potential pitfall of using the dahl approach – a case study

Abstract: Tooth wear (tooth surface loss) is an ever increasing problem which can be challenging to prevent, restore and maintain. These cases frequently have reduced inter-occlusal space and are often managed by re-organizing the occlusion or using techniques such as the Dahl approach. This approach is not without difficulties and can be particularly challenging in cases of Class II skeletal classifications. This report discusses tooth wear in a single case which initially planned the use of a Dahl approach but which was adapted following review due to distalization of the mandible, and so highlights a potential issue with this approach. CPD/Clinical Relevance: With the increasing incidence of tooth wear it is important that general dental practitioners can assess, manage and restore worn dentitions in a safe and controlled manner.

RESTORATIVE DENTAL MATERIALS

Introduction: Erosion is an escalating problem in all age groups. Dental erosioncan be defined as painless irreversible loss of dental hard tissue due to chemical processwithout the involvement of microorganisms. There are several causes of erosion includingacidic foods and drinks. They are not only harmful to teeth but it is one of the main causes offailure of restoration. Erosion is one of the main challenges to restorative materials. Therefore,the restorative materials used in the mouth should resist or show minimal change in thesesituations. A variety of restorative materials are currently recommended for erosive lesions,including resin modified glass ionomer cement, resin composite and amalgam. Each materialhas its own advantages and disadvantages, which are considered before selecting them asrestorative materials. Objectives: To compare the surface micro-hardness of three restorativematerials when exposed to three acidic beverages and distilled water. Study design: This wasan experimental study. Setting: de’Montmorency College of dentistry in collaboration withPakistan council of scientific and industrial research (PCSIR) Lahore. Period: 6 months, Nov2014- April 2015. Material &amp; Methods: Ninety six disc specimens prepared with resin modifiedglass ionomer, resin composite and amalgam restorative materials. The initial surface microhardnesstest was carried out at 1 day after mixing (before immersion) using micro-hardnesstesting machine. After base line study of micro-hardness the material specimens were subjectedto one of the storage media which was comprised of cola, apple juice, orange juice and distilledwater as control. Quantitative assessment of final surface micro-hardness was done at 2, 5 and7 days after immersion. The values obtained as base line and final vickers hardness number(VHN) for each specimen were subjected to statistical analysis. Results: Exposure to acidicbeverages decreased the surface micro-hardness of all the three restorative materials (P&lt;0.05),while distal water did not affect the surface micro-hardness of any material. The resin modifiedGIC showed greatest reduction in surface micro-hardness as compared to Amalgam and ResinComposite. The cola produced the greatest degradation effect. Conclusion: Selection ofrestorative materials should be considered in patients with tooth surface loss, especially thosewith high risk for erosive conditions. In terms of materials evaluated for this study Amalgam andResin Composite provides the greatest stability under acidic conditions.

Oral Rehabilitation of Young Adult with Amelogenesis Imperfecta

Amelogenesis imperfecta is a heterogeneous group of hereditary disorders that affect the enamel formation of the primary and permanent dentitions while the remaining tooth structure is normal. Appropriate patient care is necessary to prevent adverse effects on dental oral health, dental disfigurement, and psychological well-being. This clinical report presents a 27-year-old Chinese male with amelogenesis imperfecta (AI) and his restorative management. This clinical report presents a 27-year-old Chinese male with AI and his restorative management. Extraoral examination showed a skeletal class III profile and increased lower facial proportion. Intraorally, all the permanent dentition was hypoplastic with noticeable tooth surface loss and a yellow-brown appearance. This was complicated with a mild maloc-clusion and food packing on his posterior teeth. The patient wanted to improve his appearance and masticatory efficiency. Orthodontic treatment was performed to treat the mild malocclu-sion and create physiological interproximal spacing to minimize tooth preparation and facilitate oral hygiene. This report demonstrates how a multidisciplinary approach for the management of AI can achieve a predictable, functional, and esthetic outcome. Orthodontic treatment facilitated a conservative prosthodontic treatment outcome by selectively increasing interproximal space, minimizing tooth preparation, correcting posterior bilateral cross-bite, as well as an anterior reverse overjet and derotation of the canines. This case report demonstrates the effective restoration of AI using a multidisciplinary approach to overcome crowding using a relatively conservative approach.

Digital Image Correlation and Strain Gauges to Map and Compare Strain in Teeth with Different Quantity and Quality of Remaining Tooth Structure.

To evaluate strain in teeth with differing quality and quantity of tooth surface loss by utilizing surface displacement field measured using digital image correlation (DIC) and strain gauges (SG). A total of 80 mesio-occlusodistal preparations were carried out in human maxillary premolars. Ten sound premolars served as a control group, and treated samples were divided into two groups of 40 each according to the composition of the prepared walls (composed of either enamel and dentin [E + De] or dentin only [De]). Each group was then divided into four subgroups of 10 each according to the selected cusp height-to-width ratio (A = 2:1 mm; B = 3:1 mm; C = 3:1.5 mm; D = 4.5:1.5 mm). The samples were uni-axially loaded to 130 N, and strain was recorded using DIC and SG. With SG testing, control samples recorded the lowest strain values and were significantly different from all test groups. However, DIC failed to detect strain in control samples, as it was too low. With DIC, group D showed the lowest strain readings among all the dimension groups and was significantly different from groups A and B, but the composition of the remaining tooth structure did not show any significant effects. With SG testing, remaining wall dimension and composition both had significant effects: Group A scored the highest strain at all compositions, and E + De had better resistance to load stresses than De only. For both testing methodologies, height (≥ 3 mm) and width (1 to 1.5 mm) of the remaining tooth structure had an effect on strain. Tooth compositions of E + De resisted strain better than De counterparts at all dimensions.

Survival Rates from Fracture of Endodontically Treated Premolars Restored with Full-coverage Crowns or Direct Resin Composite Restorations: A Retrospective Study

IntroductionThe aim of the present study was to compare the survival rates against fracture of premolar endodontically treated teeth (ETT) restored with resin composite or crowns and to identify risk factors associated with the fracture. MethodsData from dental records and radiographs of premolar ETT with postendodontic restorations (ie, resin composite or crowns) were collected between 2012 and 2016 and selected following selected inclusion and exclusion criteria. Tooth location, type of restoration, number of proximal contacts, and amount of tooth surface loss were recorded. The incidence and restorability of postendodontic fractures were identified. Survival rates against fracture of the 2 restoration types were calculated using Kaplan-Meier survival analysis. Any potential factors associated with fractures were identified using Cox proportional hazards models. ResultsThe survival rate against fracture of ETT restored with crowns (95.1%) was higher than resin composite (77.0%). ETT restored with resin composite with 1 or 2 tooth surface losses and 2 proximal contacts had a high survival rate of 88.5% that was not significantly different from ETT with crowns. A higher incidence of restorability after fracture was observed in teeth restored with resin composite than crowns. The type of restoration and number of proximal contacts were identified as potential risk factors associated with fracture incidence. ConclusionsThe survival rate against fracture of ETT restored with crowns was higher than resin composite. However, ETT with 1 or 2 tooth surface losses and 2 proximal contacts and restored with resin composite showed a high survival rate that was comparable with ETT restored with crowns.

Erosive Tooth Wear: Knowledge Of Diagnosis And Treatment Strategies Among Private Dental Practitioners In Kuantan, Pahang

Introduction: Awareness of erosive tooth wear (ETW) by the public is still low and most dental practitioners overlooked the very early stages dismissing minor tooth surface loss of erosive tooth wear. Therefore, this study aimed to assess knowledge of diagnosis and treatment strategies of ETW among private dental practitioners (PDP) in Kuantan. Materials and Methods: A crosssectional study was conducted in Kuantan private clinics involving PDP and general dental practitioners who performed locum by using convenience sampling. A self-administered validated questionnaire was distributed and descriptive analysis was performed. Results: Overall response rate was 75%. Results indicated that majority of participants (79.2%) received formal education about ETW. About half of participants further learned through continuous dental education. All participants agreed that carbonated drink was the cause of ETW and majority of them reported that gastro-esophageal reflux diseases and pickles also contributed to ETW. Regarding ETW documentation, majority of participants (79%) preferred case notes. Nevertheless, 40.9% and 36.4% record at tooth surface level and individual level respectively. In term of specific scoring in assessing ETW, 79% of them did not know about it. Most of participants prefer giving oral hygiene instruction and diet counseling as preventive measures; however usage of fluorides was not prioritized. 77% of participants never referred case to dental specialist and prefer to treat patient by themselves. Conclusion(s): Knowledge of ETW among recruited PDP is adequate however they did not use any specific indices for ETW scoring and treatment strategies were insufficient.

Influence Of Dentist Gender And Clinical Experience On The Selection Of Posterior Restorative Dental Material: A Preliminary Study

Introduction: Dentist-related factors are one of the major influences on the material selection for restoration of carious and non-carious tooth surface loss. There were conflicting results regarding the impact of dentists' gender and age or length of clinical experience on restorative material selection for posterior dentition. The aims of this study were to determine the influence of gender and clinical experience on posterior restorative material selection among private dental practitioner in Malaysia. Materials and Methods: This is a cross sectional study, and a selfadministered questionnaire was distributed randomly using a simple random method, among general private dental practitioner in Kuala LUMPur. Data gathered then analysed using SPSS version 21.0 and alpha error was set at p10 years working experience) were inclined to choose tooth coloured restorative material over amalgam at 87% and 83.9% respectively. Chi square test revealed non-significant difference in the material selection with relation to gender (p=0.852) and clinical experience (p=0.748). Conclusion(s): The dental practitioner's gender and clinical experience in this study has no influence on the material selection for posterior restorations.
