The Arabic Version of Compulsive Exercise Test among Saudi Population; Translation and Validation.

Compulsive exercise is a condition characterized by uncontrollable exercise behaviour that may lead to severe and harmful physical and psychological consequences. Indeed, compulsive exercise is among the early symptoms of eating disorders that may affect different age groups. Globally and among Arab countries, compulsive exercise is common, while the screening methods used to assess compulsive exercise are limited. Thus, the Compulsive Exercise Test (CET) has emerged as a tool to assess cognitive, behavioural, and emotional factors related to compulsive exercise. The CET is a self-report, Likert-type scale comprising five distinct subscales. The increase in the CET scores is more likely associated with worsened pathology. Since the Arab countries lack such an assessment tool, we aimed to translate the CET into Arabic, validate the translated version, confirm the factor structures, and assess the internal consistency of the different subscales. Herein, we used the forward-backward translation method as recommended by the World Health Organization (WHO). The overall validity index of the translated version showed a score higher than 0.78, while the scale-level content validity index based on the average calculating method (S-CVI/Ave) and the agreement method (S-CVI/UA) were 0.91 and 0.58, respectively. Moreover, we recruited 399 Arabs living in Saudi to measure the internal consistency, and the value of the substantive internal consistency with Cronbach's α was 0.81. Subsequently, four of the Arabic-CET subscales had substantive internal consistency with Cronbach's α values higher than or equal to 0.70. Furthermore, the exploratory factor analysis results supported the substantial use of the five-subscale model. Taken together, our study supports using the Arabic-CET version to measure exercise compulsiveness among Arabs.

Clinical and Radiographical Outcomes of Restorative Treatment With Stainless Steel Crowns Performed by Undergraduate Dental Students in Medina, the Kingdom of Saudi Arabia.

Background and objective Stainless steel crown (SSC) placement has long been the preferred restorative treatment modality for treating multi-surface carious primary molars. This study aimed to assess the outcomes of SSC placement on primary molars performed by undergraduate dental students. Materials and methods A total of 112 children aged four to eight years were contacted for follow-ups 12 months after they underwent SSC restorations by fifth- or sixth-year female dental students in 2018-2020. Clinical and radiographic examinations were performed by trained dentists to evaluate for signs of failure. Descriptive statistics were applied for categorical variables and a Chi-squared test was used to assess the relationship between failure rate and demographic variables (i.e., age, gender, and type of tooth). Results The majority of the included children were aged seven years, with females (52.7%) slightly outnumbering males (47.3%). The failure rate clinically was 17.8%, involving one or more of the following signs: pain (16.1%), poor crown adaptation (16.1%), improper marginal seal (13.4%), fistula (6.3%), and mobility (4.5%). The rate of failure as per radiological examinations was 15%, involving one or more of the following signs: furcation involvement (9.8%), periapical radiolucency (3.6%), and pathological root resorption (1.8%). No significant association was found between failure rate and age, gender, or type of tooth. Conclusions The restorative treatment of primary molars with SSCs exhibited a high success rate when performed by less experienced undergraduate dental students from different academic levels. The failure rate did not appear to be associated with the child's age and gender or the type of tooth.

Reliability and Validity of the Arabic Version of a Questionnaire Assessing Pain, Discomfort and Related Jaw Function Impairment after Extraction of Primary Teeth in Children.

This study aims to translate a previously published English language questionnaire that assessed pain and discomfort after the extraction of primary teeth in children into Arabic, and evaluate its validity and reliability. All participating children (n = 120), aged 9 to 12-years-old, completed the 33-item Arabic version questionnaire after the extraction procedure had taken place. The questionnaire included three parts that were completed at three different times, namely, immediately, the first evening, and one week after the extraction procedure. Internal consistency, content validity, criterion validity, and factor analysis were performed. The results showed a good internal consistency (Cronbach's alpha = 0.83), acceptable criterion validity with a significantly strong correlation with the Visual Analog Scale (VAS), and satisfactory content validity (average content validity index (CVI = 0.90). The final factor model was comprised of four factors with an eigenvalue greater than 1, explaining 70% of the common variance. The identified factors were labeled as follows: Factor 1-analgesic consumption; Factor 2-expression of discomfort from the extraction site; Factor 3-perception of masticatory capability; and Factor 4-pain/discomfort from the dental extraction procedure. Based on the results, a shorter form of the questionnaire had satisfactory psychometric characteristics and can be used with children within the selected age group.

Light energy transmission and Vickers hardness ratio of bulk-fill resin based composites at different thicknesses cured by a dual-wave or a single-wave light curing unit.

PURPOSE: To quantify light energy transmission through two bulk-fill resin-based composites and to measure the top to bottom surface Vickers hardness ratio (VHratio) of samples of various incremental thicknesses, using either a single-wave or dual-wave light curing unit (LCU). METHODS: Tetric EvoCeram Bulk Fill (TECBF) and SonicFill (SF) were studied. Using MARC-RC, the irradiance delivered to the top surface of the samples 2, 3, 4 and 5 mm thick (n= 5 for each thickness) was adjusted to 800 mW/cm2 for 20 seconds (16 J/cm2) using either a single-wave, Bluephase or a dual-wave, Bluephase G2 LCUs. Light energy transmission through to the bottom surface of the specimens was measured at real time using MARC-RC. The Vickers hardness (VH) was determined using Vickers micro hardness tester and the VHratio was calculated. Data were analyzed using a general linear model in Minitab 16; α= 0.05. RESULTS: TECBF was more translucent than SF (P< 0.05). The mean VHratio was higher than 80% in 2, 3 and 4 mm increment thickness for both materials (except for 4 mm TECBF when cured with the dual-wave Bluephase G2). SF showed significantly higher VH ratio than TECBF at all different thickness levels (P< 0.05), except at the 2 mm level (P> 0.05). TECBF showed significantly greater VH ratio when cured with the single-wave Bluephase than when using the dual-wave Bluephase G2 (P< 0.05). CLINICAL SIGNIFICANCE: The transmission of light energy through to the bottom surface and the VHratio are material dependent. Although TECBF is more translucent than SF, it showed lower VHratio compared to SF when cured with dual-wave Bluephase G2.

The Use of Pit and Fissure Sealants-A Literature Review.

This paper reviews the literature and discusses the latest updates on the use of pit and fissure sealants. It demonstrates the effectiveness of pit and fissure sealants in preventing caries and the management of early carious lesions. It compares the use of different sealant materials and their indications. It describes the application technique for sealants. It also reviews the cost-effectiveness of sealants as a preventive strategy. From this review and after the discussion of recently published studies on pit and fissure sealants, it is evident that sealants are effective in caries prevention and in preventing the progression of incipient lesions. It is therefore recommended that pit and fissure sealant be applied to high-caries-risk children for optimum cost-effectiveness. It is a highly sensitive technique that needs optimum isolation, cleaning of the tooth surface, etching, and the application of a thin bonding layer for maximum benefit. Recall and repair, when needed, are important to maximize the effectiveness of such sealant use.
