DeepPlaq: Dental plaque indexing based on deep neural networks.

The selection of treatment for dental plaque is closely related to the condition of the plaque on different teeth. This study validated the ability of CNN models in assessing the dental plaque indices. In 70 (20 male and 50 female) healthy adults (18 to 55 years old), frontal and lateral view intraoral images (210) of plaque disclosing agent stained permanent and deciduous dentitions were obtained. A three-stage method was employed, where the You Look Only Once version 8 (YOLOv8) model was first used to detect the target teeth, followed by the prompt-based Segment Anything Model (SAM) segmentation algorithm to segment teeth. A new single-tooth dataset consisting of 1400 photographs was obtained after applying a two-stage method. Finally, a multi-class classification model DeepPlaq was trained and evaluated on the accuracy of dental plaque indexing based on the Quigley-Hein Index (QHI) scoring system. Classification performance was measured using accuracy, recall, precision, and F1-score. The teeth detector exhibited an accuracy (mean average precision, mAP) of approximately 0.941 ± 0.005 in identifying teeth with plaque disclosing agents. The maximum accuracy attained in the plaque indexing through DeepPlaq was 0.84 (probability that DeepPlaq scored identical to experts), and the smallest average scoring error was less than 0.25 on a 0 to 5 scale for scoring. A three-stage approach demonstrated excellent performance in detecting and segmenting target teeth, and DeepPlaq model also showed strong performance in assessing dental plaque indices. Application of artificial intelligence to the evaluation of dental plaque distribution could enhance diagnostic accuracy and treatment efficiency and accuracy.

Evaluation of DIAGNOdent pen for initial occlusal caries diagnosis in permanent teeth

BackgroundTo verify the validity of diagnosing initial caries on occlusal surface of permanent posterior teeth by laser fluorescence instrument DIAGNOdent pen.MethodsPatients from School of Stomatology in Wuhan University were selected and their posterior teeth were examined using DIAGNOdent pen and the International Caries Detection and Assessment System (ICDAS II) by an experienced dentist. After teeth extraction, histological criteria were used to determine the severity of the lesions. The sensitivity, specificity, accuracy, the area under the curve (AUC), and correlation of DIAGNOdent pen and ICDAS II were analyzed compared with histological criteria. Examiners’ agreement was measured.ResultsThe sensitivity range was 0.440-1 while that of specificity was 0.750–0.994. The accuracy and AUC were above 80% and 0.7 respectively. Consistency of examiners’ kappa values of ICDAS II, DIAGNOdent pen, and histological criteria were ranged from 0.629 to 0.840.ConclusionsICDAS II and DIAGNOdent pen can be effectively used in tandem or independently for the assessment of initial caries.

Permanent tooth avulsions: A retrospective analysis of the demographics and aetiology of cases at a tertiary hospital in Sydney, Australia

AbstractThis retrospective analysis reviewed the demographics of patients sustaining dental avulsion injuries at a tertiary dental hospital in Sydney, Australia. Data were extracted from dental records of patients who presented with avulsed permanent anterior teeth and were treated between 1 January 2001 and 30 June 2021. Demographic, clinical and radiographic data from 91 patients with 117 avulsed permanent anterior teeth were available for analysis. The median age of the patients was 12 years (IQR 9.0–17.0). Males accounted for 68.4% of avulsion injuries. Non‐organised sports were the most common cause of injury (42.7%). Maxillary central incisors were the most frequently avulsed tooth (83.3%). Peak prevalence of injuries occurred on the weekend. The findings from this study may reflect regional factors such as climate and participation in sport. Anticipatory guidance should be provided to patients at elevated risk of dental avulsion.

RELATIONSHIP BETWEEN TOOTH BRUSHING BEHAVIOR AND DENTAL CARIES IN CHILDREN AT 27 SUNGAI SAPIH PUBLIC ELEMENTARY SCHOOL KURANJI, PADANG CITY

Caries is often experienced in mid-childhood 10-12 years which is referred to as a vulnerable period, because it is at that time that milk teeth begin to fall out and the first permanent teeth begin to grow. The 2018 West Sumatra Basic Health Research Results ( Rikesdas ) stated that 41.74% of children aged 10-14 years experience dental caries, while the prevalence of dental caries in Padang City is around 6,154 children, which is 36.71% .

It is recommended for dental health workers to educate schools about the importance of dental and oral care and how to brush their teeth properly and correctly so that they can increase students' knowledge and behavior in brushing their teeth for the better.

Can a behaviour change toothbrushing intervention prevent dental caries in 11-13-year-olds?

The Brushing RemInder 4 Good oral HealTh (BRIGHT) multi-centre randomized controlled trial was based in state-funded secondary schools in England, Wales and Scotland. It had two arms, aiming to assess the clinical and cost effectiveness of a 50 min education session and twice daily brush reminder text messages on toothbrushing and caries rates, compared to the normal education curriculum and no SMS. Outcomes were assessed at intervals over 2.5 years and were assessor-blinded. Pupils aged 11-13 were recruited from participating schools, and in each school randomised via year group to either the intervention or control group following baseline assessments by calibrated dental professionals. Exclusion criteria included not having a functioning mobile phone. The primary outcome, D4-6 MFT (Decayed, Missing and Filled Teeth), was analysed using mixed-effect logistic regression and sensitivity analyses were conducted. A cost-utility analysis was also undertaken. In total 42 schools, containing 84 year groups were randomised, and 4680 pupils were in the final sample. 663 pupils withdrew from follow up. At 6 months, there was evidence that intervention group pupils were more likely to report brushing at least twice per day However, by 2.5 years this effect was no longer evident. 2383 participants had a valid dental assessment at both baseline and 2.5 years, with 514 children in the intervention and 529 children in the control group presenting with obvious decay experience in at least one permanent tooth after 2.5 years. The intervention was estimated to have a 7% chance of being cost-effective. Over the 2.5-year follow-up, there were no significant differences in QALYs and costs between groups. The findings from the BRIGHT trial indicate no evidence of a statistically significant difference between the intervention and control groups for the prevalence of caries after 2.5-years. The behaviour change intervention did not translate into a reduction in caries rates.

Direct Composite Restorations on Permanent Teeth in the Anterior and Posterior Region - An Evidence-Based Clinical Practice Guideline - Part 2: Recommendations for Composite Processing.

Part 2 of this German S3 clinical practice guideline provides recommendations for the process of manufacturing composite restorations. It covers key aspects like caries removal, field isolation, matrix and adhesive techniques, as well as light curing and polishing. The outcomes of interest include survival rates and restoration quality. A systematic literature search was conducted by two methodologists using MEDLINE and the Cochrane Library via the OVID platform, including studies up to December 2021. Additionally, the reference lists of relevant manuscripts were manually reviewed. Six PICO questions were developed to guide the search. Consensus-based recommendations were for- mulated by a panel of dental professionals from 20 national societies and organizations based on the collected evidence and ex- pert opinion. The guideline advocates for one-stage selective caries removal near the pulp and underscores the effectiveness of various isolation techniques, adhesive systems, and the crucial role of light polymerization. The use of anatomically pre- formed sectional matrices and phosphoric acid etching is recommended to enhance restoration quality. Additionally, polish- ing composite restorations is advised to improve surface finish. This guideline provides comprehensive recommendations that inform clinicians on optimizing the composite restor- ation manufacturing processes. The adoption of these best practices can improve the quality and longevity of dental restorations.

Direct Composite Restorations on Permanent Teeth in the Anterior and Posterior Region - An Evidence-Based Clinical Practice Guideline - Part 1: Indications for Composite Restorations.

This German S3 clinical practice guideline offers evidence-based recommendations for the use of composite materials in direct restorations of permanent teeth. Outcomes considered were the survival rates and restoration quality and process quality of the manufacturing process. Part 1 of this two-part presentation deals with the indication classes. A systematic literature search was conducted by two methodologists using MEDLINE and the Cochrane Library via the OVID platform, including studies up to December 2021. Six PICO questions were developed to guide the search. Recommendations were formulated by a panel of dental professionals from 20 national societies and organizations based on the collected evidence. Composite materials are a viable option for the direct restoration of cavity Classes I-V and may also be used for restorations with cusp replacement, and tooth shape corrections. In the posterior region, direct composite restorations should be preferred over indirect composite inlays. For Class V restorations, composite materials can be used if adequate contamination control and adhesive technique are ensured. The guideline is the first to provide comprehensive evidence on the use of direct composite materials. However, further long-term clinical studies with comparators such as (modified) glass-ionomer cements are necessary. Regular updates will detail the future scope and limitations of direct composite restorations.

An inverse relationship between dental fluorosis and Molar Incisor Hypomineralization in Mexican schoolchildren in an area with a high concentration of fluoride in drinking water: A cross-sectional study.

To evaluate the association between the frequency and severity of dental fluorosis and Molar Incisor Hypomineralization (MIH) in 8-12-year-old schoolchildren living in an area with a high concentration of fluoride in the drinking water. The present cross‑sectional study was conducted on Mexican children (n = 573) selected from one community presenting a drinking water fluoride concentration of 1.39 ppm/F. The prevalence of dental fluorosis was ascertained using the Thylstrup and Fejerskov Index (TFI). The presence and severity of MIH was evaluated using the European Academy of Pediatric Dentistry (EAPD) criteria. A multinomial regression model was used to estimate the odds ratio (OR) and the 95% confidence intervals (CI), using the severity of MIH as the result. The prevalence of MIH was 37.7% and, by severity, was 16.1% mild, 14.3% moderate, and 7.3% severe. The prevalence of dental fluorosis in permanent dentition was 70.9% (TFI ≥1) and, by severity, was 29.2% (TFI = 0), 45.6% (TFI 1-3) and 25.3% (TFI ≥4), while 54.5% of subjects were found to have poor oral hygiene. Schoolchildren with fluorosis (TFI ≥4) were 49% less likely [OR = 0.51; p = 0.025] to present mild MIH than children with fluorosis (TFI <4). Similarly, children with fluorosis (TFI ≥4) were 53% [OR = 0.47; p = 0.019] and 62% [OR = 0.38; p = 0.036] less likely to present moderate and severe MIH than children with fluorosis (TFI <4). An inverse relationship between the presence of fluorosis and MIH was found. The results obtained by the present study may contribute to both the early identification of disorders affecting the enamel and the creation and implementation of long-term oral health prevention, promotion, and intervention programs in the affected population.

Evaluation of microleakage of mineral trioxide aggregate and biodentine as apical barriers in simulated young permanent teeth

BackgroundApexification is a procedure that promotes apical closure by forming mineralized tissue in the apex region of a nonvital young permanent tooth. Calcium silicate-based cement like Mineral trioxide aggregate (MTA) and Biodentine are commonly employed as apical barriers to facilitate this process. Microleakage, defined as the leakage along the junction between the canal wall and filling material, is a crucial aspect to assess in MTA and Biodentine applications as apical barriers, as it directly impacts the prevention of bacterial seepage and maintenance of structural integrity. The current study aims to assess the microleakage of MTA and Biodentine when used as apical barriers in simulated young permanent teeth.MethodsFrom a total of 128 extracted teeth, 114 were selected for the study and randomly allocated into three groups: G1 (MTA), G2 (Biodentine), and G3 (Control), with 38 teeth per group. After excluding 5 teeth from each group due to issues such as canal calcification, breakage during sectioning, and procedural errors, 33 teeth were analyzed to ensure equal distribution. To simulate young permanent teeth, samples were instrumented using a person-reamer with a diameter of 1.7 mm. A 4 mm thick apical plug of MTA and Biodentine was placed in G1 and G2, respectively, while G3 was the control group. Apical microleakage in all experimental groups was assessed using a dye penetration method. Specimens were longitudinally sectioned and examined under a stereomicroscope with graded eyepiece.ResultsThe Kruskal-Wallis test revealed variations in mean apical microleakage among the groups: G1 recorded 0.67, G2–0.16, and G3–1.62, with G2 showing the lowest value and G3 group exhibiting the highest.ConclusionsBiodentine was found to excel in its ability to create a secure seal and function effectively as an apical barrier in simulated young permanent teeth. These results underscore its potential as a highly efficient material for dental applications, particularly in scenarios requiring reliable sealing and barrier formation in the root canal system of developing permanent teeth.

Management of Dens in Dente in Mesiodens (A Rare : Case Report)

Dens in dente in mesiodens is rare. Supernumerary teeth cause various complications such as failure of eruption of permanent teeth, malocclusion, development of cyst and various pathologies. So, management of such anomalies are important.

Root canal morphology of mandibular anterior permanent teeth in Turkish sub-population using two classification systems: a cone-beam computed tomography study.

This study examined the root and canal morphology of mandibular anterior teeth (MA) in the Turkish sub-population using cone-beam computed tomography (CBCT), comparing the findings based on Vertucci's and Ahmed et al. classification systems. The CBCT images were acquired using the 3D Accuitomo CBCT device. Images that were deemed suitable for visualizing the roots, canals, and the complete pulp chamber and apex were included in the study. Vertucci and Ahmed et al. classification systems were employed to determine the root canal morphology. 500 CBCT images and 3000 teeth were analyzed. Type I (1MA1) was the most frequent, followed by Type III (1MA1-2-1). 3.8% of teeth could not be classified with Vertucci system. In canine teeth, Vertucci type III (1MA1-2-1) was significantly more prevalent in males than females (p = 0.038) and Type I (1MA1) was less frequent in individuals aged 41-50 (p < 0.05). Canal divergence/merging was the most common at the middle/apical level for central (15.5%) and lateral (10.3%) teeth, and at the coronal/middle level for canine teeth (1.9%). Bilateral similarity was high for all tooth groups (> 78%). One-third of mandibular incisor teeth have two canals, with a significant number exhibiting canal divergence/merging that was separated in the middle region and merged in the apical region. The Vertucci classification was found to be inadequate in some cases, while Ahmed et al. classification was able to classify all mandibular incisors with a single code. Ahmed et al. classification is a more useful system for classifying all MA.

Age Determination Based on Open Apex Measurement in the Developing Dentition: Comparing the Accuracy of the Belgrade Age Formula (BAF) with the European Formula on a Bosnian Children Population.

The aim was to test the Belgrade age formula based on the calculation of open apices of two permanent mandibular teeth on a Bosnian children population and compare its accuracy with European formula. We included 412 panoramic images of children (204 female and 208 male) 7 to 13 years of age. We assessed the performance of both methods (the European formula and the BAF) and compared their results in both sexes. The results showed a high point of average understanding between the age estimated by chronological age and the European formula (ICC=0.927, 95% CI 0.904-0.944, p<0.001)., BAF also confirmed a high point of agreement with chronological age in boys (ICC=0.941, 95% CI 0.922-0.955, p<0.001) and girls (ICC=0.913, 95% CI 0.886-0.934, p<0.001). BAF was better than the European formula in estimating age in males (0.4448±0.9135 vs. 0.9807±0.9422). The Belgrade Age Formula (BAF) demonstrates comparable accuracy to the European formula for age determination in Bosnian children, while offering the advantage of being easier and faster to use. This makes the BAF a practical alternative in clinical and research settings where efficiency and reliability are essential.

CT-Assisted Management with Biodentine Obturation and Aesthetic Rehabilitation of a Geminated Maxillary Central Incisor with Mid-Root Fracture: A Rare Case Report

Gemination, a rare aberration in tooth development, results from the incomplete division of one tooth germ into two. In this case report, a true geminated permanent maxillary central incisor tooth with a horizontal mid-root fracture is successfully treated by non-surgical endodontic treatment. To elucidate the intricate root canal anatomy of this rare geminated incisor, we employed computed tomography imaging technology, enhancing our understanding of this complex case. Utilizing biodentine for obturation proved pivotal, as its capacity to accelerate reparative dentin formation facilitated prompt healing, particularly beneficial in fracture cases. This was followed by aesthetic rehabilitation to achieve a pleasing mesio-distal dimension for both the central incisors using a zirconia-reinforced porcelain crowns. Keywords: Computed Tomography (CT), Gemination, Horizontal root fracture, Biodentine Obturation

Dietary Preferences and Potential Impact on Dental Hard Tissue Diseases in Schoolchildren of Osh Region, Kyrgyz Republic

Dental caries, known as one of the civilization diseases, leads to chronic progressive destruction of teeth, impaired aesthetics, inflammatory and other complications. The conducted study of ethnic, dietary preferences and their potential influence on the prevalence and intensity of dental caries in schoolchildren of the Kyrgyzstan highland region showed a moderate degree of intensity and prevalence in the deciduous dentition (6-7 years) — 94.2%. In the permanent bite (11-12 years) — 95.5%. The average prevalence of caries of permanent teeth in schoolchildren 6-17 years old was 77.7%. Increased consumption of sugar-containing products and carbonated drinks was determined.

Prevalence of dental carries among school-going children aged 7–13 years in Kabul City

BackgroundDental caries is a major, multifactorial oral condition that causes the demineralization of tooth enamel and impacts approximately half of the world’s child population. This study aimed to determine the prevalence of dental caries among school-going children aged 7 to 13 years in Kabul city.MethodsThis descriptive cross-sectional study was conducted with 491 students aged 7 to 13 years in Kabul during the first half of 2019. A multistage cluster sampling method was used, in which educational zones, schools, and classes were selected. The data were collected using pre-structured questionnaires through face-to-face interviews and oral examinations of students using dental probes and mouth mirrors while adhering to infection control protocols. The collected data were analyzed using Statistical Package for Social Science version 21.0, and a p-value < 0.005 was considered as statistically significant.ResultsThe average age of the study participants was 9.9 ± 1.8 years. Boys made up approximately 45% of the participants, while 54.8% were girls. The overall prevalence of dental caries was 78.8%, with 62.1% in deciduous teeth and 42.8% in permanent teeth. Among students who did not brush their teeth, the prevalence of dental caries was 84.8%, compared to 81.7% for those who brushed once daily, 78.7% for those brushing twice daily, and 67.4% for those brushing three times daily (p = 0.022). About 10% of students had dental calculus, with a prevalence of 17.0% among those aged eleven and older, 10.0% among students aged nine to ten years, and 5.9% among students aged eight and younger (p = 0.006). Poor oral hygiene affected nearly one-third of the students, with 34.2% among boys and 30.9% among girls. Poor oral hygiene was more prevalent in students aged eight and younger (38.8%) compared to those aged eleven and older (25.9%) (p = 0.023).ConclusionsThe prevalence of dental caries among students aged 7 to 13 years in Kabul schools was similar to that in most developing countries. The prevalence of dental calculus was greater among students aged eleven years and older. Over 99% of the students surveyed had not undergone any dental treatment.

Comparison of the accuracy and bias of Demirjian’s method for East Asian children and development of Japanese population-specific age estimation formulae

Despite the increased global mobility owing to the development of the international community, there remains a need for population-specific methods to estimate children’s ages. Therefore, this study aimed to substantiate the necessity for a Japanese-specific age estimation method by contrasting the formerly reported age estimation accuracy and bias using Demirjian’s method for Chinese, Taiwanese, South Korean, and Japanese children. We analyzed 1,558 panoramic radiographs from Japanese children (777 boys and 781 girls), assessed the maturity of seven left permanent teeth using Demirjian’s criteria, and calculated the estimated age using Demirjian’s method. The accuracy of the estimated ages was compared with previous reports of children from other East Asian countries which used the same age estimation method. Chinese, Taiwanese, and South Korean boys and girls were all reported to be older than their chronological ages, with the Eastern and Northern Chinese regions being the only exceptions. The same was true for Japanese children: the estimated ages of both sexes tended to be higher than their chronological age. However, there were significant variations in the values, indicating the differences in tooth growth and development between East Asian countries and sexes. Therefore, new regression equations specific to the Japanese population were formulated, and their accuracy was evaluated as the final result of this study.

Genetic and environmental contributions to the development of soft tissue facial profile: a twin study.

This study aimed to determine the relative contribution of genetic and environmental factors in the phenotypic variation of the soft tissue facial profile during the mixed dentition and the permanent dentition stages. In this retrospective cohort study, standardized facial profile photographs of 139 twin pairs (55 monozygotic and 84 dizygotic) were obtained from archival records at the Adelaide Dental School. Photographic analysis used 12 angular and 14 linear facial profile measurements from the mixed dentition (7-11 years) to the permanent dentition (12-17 years) stages. A genetic analysis was performed using a univariate structural equation model adhering to the normal assumptions of a twin model. In the mixed dentition stage, the additive genetic (A) and unique environment (E) model, AE model, was the most parsimonious in explaining the observed phenotypic variance for all 26 facial traits with the narrow-sense heritability estimates ranging between 0.38 and 0.79. In the permanent dentition, the AE model was the most parsimonious for 20 out of 26 traits, however, the variance of six traits, particularly those in the lower third of the face, was best explained by the shared environmental and unique environmental factors. This study exclusively included twins of European ancestry. The soft tissue facial profile demonstrated dynamic genetic and environmental influences with a greater additive genetic influence during the mixed dentition and the early stages of the permanent dentition. However, there was evidence of increasing environmental influence in the lower third of the face during the early stages of the permanent dentition.

Prevalence and Association of Caries and Enamel Hypomineralisation/Molar-Incisor Hypomineralisation in 8- to 10-Year-Old Children from Bavaria, Germany

Introduction: The aim of this cross-sectional epidemiological study was to record caries and enamel hypomineralisation (EH), including molar-incisor hypomineralisation (MIH), and assess associations between both entities in 8- to 10-year-olds from Bavaria, Germany. Methods: A total of 5,418 children (mean age 9.8 years; 2,726 females, 2,692 males) were examined using the dmft/DMFT index with additional inclusion of initial or non-cavitated carious lesions (it/IT). EHs were recorded in the primary (eh) and permanent dentition (EH), and individuals with different EH phenotypes were determined as follows: at least one EH, at least one hypomineralised second primary molar (HSPM), at least one hypomineralised first permanent molar (MIH), and at least one hypomineralised first permanent molar and incisor (M+IH). Multiple logistic regression models were constructed to assess association between caries and EH. Results: The percentage of children without caries in the permanent dentition (DMF = 0) was 88.9%. When data regarding initial carious lesions were included (IDMF = 0), the prevalence decreased to 75.7%. The caries experience was idmf/t = 1.6 and the IDMF/T = 0.6. The mean number of carious teeth in subjects with no eh/EH was higher than that in subjects with HSPM, MIH, or M+IH. The presence of HSPM, MIH, and M+IH was associated with a significantly lower probability of caries in the permanent dentition; the corresponding adjusted odds ratios were 0.55 (95% CI: 0.41−0.75), 0.67 (95% CI: 0.56−0.81), and 0.54 (95% CI: 0.41−0.72), respectively. Conclusions: Caries and EH are prevalent conditions in 8- to 10-year-old Bavarian schoolchildren; both dental diseases were negatively associated with each other.

Vascular Anomalies and Congenital Infiltrating Lipomatosis May Affect Dental Maturation and Development - a Case Control Study.

Vascular anomalies are often associated with hypertrophy and asymmetry of soft tissues and bony structures. The aim of this retrospective cross-sectional radiographic study was to evaluate dental maturation and development in patients with facial vascular anomalies and congenital infiltrating lipomatosis. A sample of 342 patients with different vascular anomalies or congenital infiltrating lipomatosis involving the head and neck area was narrowed down to 31 patients with dental panoramic radiographs taken in the mixed dentition. A control group of 172 age-matched healthy subjects was used. Individual permanent teeth were given a maturation score from 1 to 12 and alveolar eruption stage according to Haavikko et al. 1970. The laterality of the anomaly was noted if applicable. Differences in dental development between affected and unaffected sides were recorded. The study data included both syndromic and non-syndromic vascular anomalies as well as congenital infiltrating lipomatosis and segmental odontomaxillary dysplasia. Teeth on the side of the anomaly were more developed and the eruption of teeth was accelerated with canines, premolars and second molars being most affected. Interestingly all the patients with Sturge-Weber syndrome (n = 4) and infiltrating lipomatosis (n = 2) showed accelerated dental maturation of multiple permanent teeth on the side of the anomaly. Hypodontia, dental root resorption and macrodontia were also found. Accelerated development and eruption of permanent teeth unilaterally in patients with vascular anomalies and congenital infiltrating lipomatosis may have a significant impact on the developing occlusion and should be thus followed by an orthodontist.

The effectiveness of partial pulpotomy compared with full pulpotomy in managing deep caries in vital permanent teeth with a diagnosis of non-traumatic pulpitis.

Pulpitis may be pain free or alternatively characterized by mild to severe pain and associated symptoms. Evidence has recently emerged that patients presenting with carious pulp exposure range of symptoms can be treated effectively with pulpotomy. The current systematic review aimed to answer the following research question: "In patients with deep caries lesions in permanent teeth associated with no symptoms, reversible pulpitis or signs and symptoms indicative of irreversible pulpitis (P), is partial pulpotomy (I) as effective as full pulpotomy (C), in terms of a combination of patient and clinical reported outcomes (O), with "tooth survival" as the most critical outcome? The systematic literature search was conducted in the following electronic databases: OVID, Scopus, PubMed (Including MEDLINE), and Cochrane Central Register of Controlled Trials (CENTRAL) supplemented with Grey literature and hand searching of relevant journals. The English language clinical trials comparing the patient and clinical reported outcomes between partial and full/complete were included. After a structured literature search, two authors independently performed study selection, extracted data and performed a risk of bias assessment; a third reviewer resolved disagreements. As there were only two studies with different exclusion criteria, no meta-analysis was performed and the quality of evidence was assessed by the GRADE approach. After study selection a total of two randomised clinical trials with a total of 156 teeth were included both for the management of teeth with irreversible pulpitis. There were no studies for asymptomatic teeth or teeth with reversible pulpitis. A "Low" risk of bias was noted for both studies with a high level of overall evidence. A meta-analysis was not carried out due to differences in inclusion criteria between the studies related principally to caries depth. Both studies reported a high rate of clinical success for pulpotomy with a pooled unadjusted success rate for full pulpotomy of 90% and 83% partial pulpotomy of at 1-year; however, no significant difference between the treatments was noted in either study. There was significantly reduced postoperative pain reported in the full pulpotomy group over 1-week compared with the partial pulpotomy in one but not in the other study. Pulpotomy as a definitive treatment modality is as effective in managing teeth exhibiting signs and symptoms indicative of irreversible pulpitis and challenges the established protocols to manage this condition. Although based on only two RCTs with a limited number of patients, no difference was shown in terms of clinical or radiographic outcome or postoperative pain between groups. Further well designed randomised clinical trials of longer duration are required in this area to improve the evidence available. There is no consistent difference in patient-reported pain between partial and full pulpotomy at day 7 postoperatively and the clinical success rate was similar after 1 year for both treatment modalities.
