Objective: The aim of this retrospective study was to analyze the survival probability of selective caries removal (SCR) treatments in the primary teeth of children with high caries experience and factors potentially associated with treatment failure. Methods: The sample included SCR treatments conducted in anterior and posterior teeth without sedation or general anesthesia among children attending a university dental service. Kaplan-Meier survival analysis was used to estimate the longevity of restorations and multivariate Cox regression with shared frailty was used to assess risk factors. Results: A total of 284 SCR treatments in 88 children (aged 5.2 ± 1.91 years) with high caries experience (mean dmft/DMFT = 11.1 ± 5.04) were analyzed. The 3-year survival reached 48.8%, with an annual failure rate of 21.2%. Restorative failures (n = 60) were found more frequently compared to pulp complications (n = 12). SCR performed in anterior primary teeth were more prone to failure (hazard ratio = 3.6, 95% CI: 1.94; 6.71). Patients with a higher amount of visible plaque experienced more failures in SCR treatments (hazard ratio 3.0, 95% CI:1.27; 7.07). Conclusions: In this retrospective study, SCR showed restricted survival when compared to other prospective clinical trials. Patient-related factors, especially the young age and high caries experience of the children, may represent a challenge for restoration survival. Regardless of the caries removal technique or restorative material, cariogenic biofilm has a negative effect on the survival of restorations, probably by acting directly on material deterioration and, particularly, on the development of new caries lesions of rapid progression.

Selective Caries Removal

Abstract Background Dental caries is one of the most prevalent non-communicable disease globally and can have serious health sequelae impacting negatively on quality of life. In the UK most adults experience dental caries during their lifetime and the 2009 Adult Dental Health Survey reported that 85% of adults have at least one dental restoration. Conservative removal of tooth tissue for both primary and secondary caries reduces the risk of failure due to tooth-restoration, complex fracture as well as remaining tooth surfaces being less vulnerable to further caries. However, despite its prevalence there is no consensus on how much caries to remove prior to placing a restoration to achieve optimal outcomes. Evidence for selective compared to complete or near-complete caries removal suggests there may be benefits for selective removal in sustaining tooth vitality, therefore avoiding abscess formation and pain, so eliminating the need for more complex and costly treatment or eventual tooth loss. However, the evidence is of low scientific quality and mainly gleaned from studies in primary teeth. Method This is a pragmatic, multi-centre, two-arm patient randomised controlled clinical trial including an internal pilot set in primary dental care in Scotland and England. Dental health professionals will recruit 623 participants over 12-years of age with deep carious lesions in their permanent posterior teeth. Participants will have a single tooth randomised to either the selective caries removal or complete caries removal treatment arm. Baseline measures and outcome data (during the 3-year follow-up period) will be assessed through clinical examination, patient questionnaires and NHS databases. A mixed-method process evaluation will complement the clinical and economic outcome evaluation and examine implementation, mechanisms of impact and context. The primary outcome at three years is sustained tooth vitality. The primary economic outcome is net benefit modelled over a lifetime horizon. Clinical secondary outcomes include pulp exposure, progession of caries, restoration failure; as well as patient-centred and economic outcomes. Discussion SCRiPT will provide evidence for the most clinically effective and cost-beneficial approach to managing deep carious lesions in permanent posterior teeth in primary care. This will support general dental practitioners, patients and policy makers in decision making. Trial Registration Trial registry: ISRCTN. Trial registration number: ISRCTN76503940.

Oro-antral perforation (OAP) could be misdiagnosed if the incidence and risk factors are unknown and its consequence could be worrisome. We aimed to determine the incidence and risk factors of oro-antral perforations after teeth extraction. A retrospective study of forceps extracted upper posterior teeth over a ten-year period from September 2008 to November 2018 was done at our hospital in Nigeria. In univariate analysis, the predictors were age, gender, experience of surgeon, site of tooth, side of surgery, use of elevators while the outcome variable was oroantral perforations. Logistic regression was also done to determine the risk factors associated OAP. We used SPSS Version 17(SPSS Inc, Chicago, USA) to perform descriptive and inferential statistical analysis. P-Value less than 0.05 was considered statistically significant. Out of the total 26,372 dental extractions during the ten-year period, 54 (0.2%) extraction cases (33 males, 21 females) had oro-antral perforations. Their mean age was 54.8± 10.6years (ranging from 21 to78 years). The highest incidence occurred in the sixth decade of life. Only the location of teeth had a significant association with oro-antral perforations. The location of upper first molar was (OR = 1.85, P=0.00) identified as a significant risk factor. The incidence of OAP is significantly lower in Nigerians and was 0.2% although there could be a population variability. The position of the upper first molar was a factor found to be associated and predictive of the OAP but age, gender, number of extractions per visit, side of operation and the surgeon’s experience were not. The findings will help surgeons to predict occurrence of OAP knowing its risk factors.

Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.

Prevalence Of Anemia

BACKGROUND Anemia is a worldwide major problem known to affect people throughout the world. It has an adverse effect on both the social and economic development. The worldwide prevalence of anemia is 9% in developed nations. The global estimate indicates that 293.1 million of children under five years, approximately 43%, are anaemic worldwide and 28.5% of these children are found in sub Saharan Africa. In Zambia specifically Kasempa, no documented studies on prevalence have been done. Despite iron supplementation being given to pregnant women and the availability of blood transfusion. The burden of the disease remains high as determined by high mortality and morbidity. This study aims at determining the prevalence of anemia and the associated risk factors among under-five children at Mukinge Mission Hospital in Kasempa District. Knowledge of prevalence and the associated risk factors of anaemia will enhance early detection and timely management. OBJECTIVE 1.To determine the hemoglobin status of anaemia by its severity among anaemic under-five children admitted at Mukinge Mission Hospital. 2.To assess the association of anaemia with Malaria among under-five children admitted at Mukinge Mission Hospital. METHODS This was a retrospective study review of under-five children that were diagnosed and managed of Anemia at Mukinge Missions Hospital, over the period of period of 2015, 2017 and 2018. .Data of the variables of interest was extracted and analyzed using SPSS. RESULTS A sample population of 52 children was included in our study. The majority of the children were females 28 (53.8 %) and 24 (46.2 %) were Males. It was found that moderate and severe anaemia was 17.3% and 82.7 % respectively. Additionally, Majority of the anaemic children (75%) had Normocytic anaemia. The Pearson Chi square test revealed no statistical relationship between the variables; Malaria (p=0.58), Age (P=0.82), Gender (P=0.91). CONCLUSIONS According to our study, 39 (75%) had normal mean corpuscular volume which could suggest chronic diseases and sickle cell anemia. 11 (21.2%) had a low mean corpuscular volume indicating Microcytic anemia which could suggest diseases such as iron deficiency and thalassemia among many other causes. However, we were unable to determine the specific cause of anemia.

Abstract Background Radical resection is associated with good prognosis among patients with cT1/T2Nx rectal cancer. However, still some of the patients experienced cancer recurrence following radical resection. This study tried to identify the postoperative risk factors of local recurrence and distant metastasis separately. Methods This retrospective, single-center study comprised of 279 consecutive patients from Linkou branch of Chang Gung Memorial Hospital in 2005–2016 with rectal adenocarcinoma, pT1/T2N0M0 at distance from anal verge ≤ 8cm, who received curative radical resection. Results The study included 279 patients with pT1/pT2N0 mid-low rectal cancer with median follow-up of 73.5 months. Nineteen (6.8%) patients had disease recurrence in total. Nine (3.2%) of them had local recurrence, and fourteen (5.0%) of them had distant metastasis. Distal resection margin < 0.9 (cm) (hazard ratio = 4.9, p = 0.050) was the risk factor of local recurrence. Preoperative carcinoembryonic antigen (CEA) ≥ 5 ng/mL (hazard ratio = 9.3, p = 0.0003), lymph node yield (LNY) < 14 (hazard ratio = 5.0, p = 0.006), and distal resection margin < 1.4cm (hazard ratio = 4.0, p = 0.035) were the risk factors of distant metastasis. Conclusion For patients with pT1/pT2N0 mid-low rectal cancer, current multidisciplinary treatment brings acceptable survival outcome. Insufficient distal resection margin attracted the awareness of risk factors for local recurrence and distant metastasis as a foundation for future research.
