Minimally invasive access cavities in endodontics

Background: The access cavity is a critical stage in root canal therapy and it may influence the subsequent steps of the treatment. The new minimally invasive endodontic access cavity preparation concept aims to preserve sound tooth structure by conserving as much intact dentine as possible including the pulp chamber's roof, to keep the teeth from fracturing during and after endodontic treatment. While there is great interest in such access opening designs in numerous publications, still there is a lack of scientific evidence to support the application of such modern access cavity designs in clinical practice. This review aims to critically examine the literature on minimal access cavity preparations, explain the effect of minimally invasive access cavity designs on various aspects of root canal treatment, and identify areas where additional research is required. Data: An electronic search for English-language articles was performed using the following databases: Google Scholar, PubMed, and Research Gate. The following keywords were used: "minimally invasive access cavity", "conservative endodontic cavity ", and "classification of access cavity". Study selection: 64 papers that were the most relevant to the topics in this review were selected between 1969 to 26 February 2022. Conclusions: Minimally invasive access cavities can be classified into conservative, ultraconservative, truss access, caries and restorative-driven cavities. There is a deficiency of proof that a minimally invasive access cavity maintains the resistance to fracture of endodontically treated teeth greater than traditional access cavities. There was no difference in the percentage of untouched walls and debris removal in teeth with conservative vs traditional access cavities, however, truss and ultraconservative access cavities resulted in poor irrigation efficacy compared to traditional ones. Also, the lower cyclic fatigue resistance of rotary instruments and root canal obturation with voids were associated with minimally invasive access cavities. The studies about minimally invasive access cavities still have a wide range of methodological disadvantages or register unsatisfactory or inconclusive results. Therefore, further research on this topic is needed especially with the everyday advancement of techniques and armamentarium used in endodontics.

Legal certainty through clarity and easy access to the law

The basis of legal clarity is contrary to the idea of natural justice, it is fair and fair that the law is clear and easy to understand, and this principle is today one of the most important elements of legal certainty through which the legislation is sought and the individuals are assured of their rights and subject to the obligations incumbent upon them , Clarity is achieved by paying attention to the issue of legal drafting and assigning it to specialists, with the aim of achieving the application of the rule of law and good governance and enacting well-developed and sophisticated legislation, in harmony with the Constitution  and not  in contradiction  with other laws , and  a concept  in the general public a

Open Access Esophagogastroduodenoscopy.

Background: Open access gastroduodenoscopy allows general practitioners to request gastroduodenoscopy without prior referral to a specialist. Endoscopy of the upper gastrointestinal tract in experienced hands has definite advantages over conventional barium-meal examination.
Patients and Methods: A total of 266 patients who were referred directly from general practitioner or a specialist attending for esophagogastroduodenoscopy (EGD) to the Endoscopy Unit At Al-Kindi Teaching Hospital from September- 2008 to Feb-2010 as an open access policy. Six inclusion criteria were used to include patients in our study group , while 136 patients had underwent EGD were referred from outpatient clinics of the hospital

A survey/ Development of Passive Optical Access Networks Technologies

The bandwidth requirements of telecommunication network users increased rapidly during the last decades. Optical access technologies must provide the bandwidth demand for each user. The passive optical access networks (PONs) support a maximum data rate of 100 Gbps by using the Orthogonal Frequency Division Multiplexing (OFDM) technique in the optical access network. In this paper, the optical broadband access networks with many techniques from Time Division Multiplexing Passive Optical Networks (TDM PON) to Orthogonal Frequency Division Multiplex Passive Optical Networks (OFDM PON) are presented. The architectures, advantages, disadvantages, and main parameters of these optical access networks are discussed and reported which have many ad

Obstacles to women's access to the positions of leadership in the university from their point of view

The problem of research is the need to find out the obstacles and difficulties facing women in accessing leadership positions at the University of Baghdad from their point of view. The importance of research comes from the importance of women in the university and their vital role in the development of society. The research objectives summarized the most important obstacles facing women Access to the leadership positions in the university and the relative weight of these obstacles as well as trying to identify differences in their view of these obstacles according to the variables of specialization (scientific, human) and the scientific title (Professor, Assistant Professor, Teacher, Assistant Lecturer). They were (144) university female

A An Authentication and Access Control Model for Healthcare based Cloud Services

Electronic Health Record (EHR) systems are used as an efficient and effective method of exchanging patients’ health information with doctors and other key stakeholders in the health sector to obtain improved patient treatment decisions and diagnoses. As a result, questions regarding the security of sensitive user data are highlighted. To encourage people to move their sensitive health records to cloud networks, a secure authentication and access control mechanism that protects users’ data should be established. Furthermore, authentication and access control schemes are essential in the protection of health data, as numerous responsibilities exist to ensure security and privacy in a network. So, the main goal of our s

Assessment of Tissue Eosinophilic Infiltration in Invasive Mammary Carcinoma

Background: Stromal inflammatory cells in malignant tissue have recently gained increasing interest. Unlike the extensive research on tumor‐infiltrating lymphocytes, published data about tumor‐infiltrating eosinophils in breast cancer are scarce. Furthermore, similar studies have yet to be conducted in Iraq.

Aims: The objective of this study is to examine the presence of eosinophilic infiltration by direct visualization using light microscopy and to analyze its relationship with other histological parameters in a group of Iraqi women diagnosed with invasive mammary cancer.

Methods and material: A retrospective study enrolled 90 h

The Role of Interleukin-10 in Women with Metastatic Invasive Ductal Carcinoma

Background: Breast cancer is the malignant tumor that forms from the uncontrolled growth of abnormal breast cells. It usually affects tissues involved in milk production (Ductal and lobular tissues). It is the most common malignancy in women and it remains one of the greatest health threats facing women around the world as we enter the 21st century.
Objectives: To estimate the role of IL-10 in the progression of invasive ductal carcinoma.
Patients and Method: Seventy three metastatic invasive ductal carcinoma Iraqi women were admitted to Nuclear Medicine Hospital in Baghdad and 15 samples of apparently healthy women were involved as a control. The blood samples (2 mL) were drown from all studied cases in order to be used for measur
