ABSTRACT
Introduction: Dental and oral health problems in the world are still very concerning. Many dental health programs have been carried out. Plaque control is one way to maintain oral hygiene. The research objective was to determine the effectiveness of a dental health program based on plaque control in elementary school-age children. A systemic review of the meta-analysis was designed based on the Preferred Reporting Item for System Review and Metha Analysis). Methods and Material: Data search was conducted on the PubMed and Google Scholar databases. Articles published between 2012-2022 with inclusion criteria: Population (P): Children aged 6-12 years boys and girls. Intervention (I): Dental health education for plaque control programs in schools. Comparison (C): schools without dental health programs. Out came (O): Index plaque. Study Design (S): Experimental Study with Random Control Trial. The keywords used are: Dental Health Education. Exclusion criteria: research without ethical clearance, children with special needs. Screening process: Screening was carried out by 4 (four) researchers. Statistical Analysis used: Analisys data used Revman. Results: In the research results table it can be seen that there is a difference in plaque scores between the pre test and post test. And the P value between the intervention group and the control group found a significant difference. Conclusions: Dental health education programs conducted in schools can reduce plaque scores in children 6-12 years old.

ABSTRACT
Cutaneous odontogenic fistulas or sinus tracts are frequently misdiagnosed and incorrectly treated, leading to unnecessary procedures and patient suffering. A 30 year old patient referred to us with a chronically draining lesion on his cheek. The clinical and radiologic examination reveal a pulpal necrosis of a decayed first molar which is the most probale dental origin. The absence of total healing of cutaneous sinus tract after endodontic treatment of the first mandibular molar lead to search an eventual second etiology; a disinclused third molar. After the extraction of the disinclused third molar, the lesion showed an obvious healing. This double etiology has extended the treatment and delayed the healing.

ABSTRACT
Background: In dentures that involve soft liner materials, it is important that the attachment to soft liners is preserved for an extended period to ensure maintenance of prosthetic parts and patient satisfaction. Debonding can be prevented by a variety of acrylic surface treatments to enhance the connection between the different materials. Methods: 30 specimens were fabricated (30 soft-liner specimens bonded to 30 acrylic specimens). All specimens were 75mm x 10mm x 2mm in dimensions. After bonding, 10 specimens were categorized into each group according to each surface treatment. Acrylic bonding surfaces were treated according to each method and a primer was then applied. Soft liner was mixed and poured inside the matrix part of the mold with acrylic specimens. Peel strength test was measured using a universal testing machine. Specimens were categorized according to failure mode into cohesive, adhesive, and mixed failures. Results: homogeneity of variance and One way ANOVA were utilized. Ethyl acetate group with had the highest peel strength values (4.5138) followed by sandblasting group (3.4633) and silicon carbide paper group (2.9082) respectively. Conclusions: Acrylic specimens treated by ethyl acetate solution, sandblasting, and Silicon carbide paper before bonding to soft liners can provide significant increase in peel strength values which can improve the maintenance of prosthetic parts.

ABSTRACT
Marcus Gunn Jaw-Winking Syndrome (MGJWS) is due to aberrant innervation of the levator muscle of the upper eyelid by a branch of the motor division of the trigeminal nerve that supplies the muscles of mastication. MGJWS is often congenital in origin and usually presents unilaterally. Here we describe a case of unilateral MGJWS in a 6-year-old female patient with unilateral ptosis.

ABSTRACT
Amelogenesis imperfecta (AI) is a genetic disorder affecting enamel development affecting its structure and clinical appearance. It can affect both primary and/or permanent teeth and may be linked with nephrocalcinosis. Autosomal dominant inheritance is the main transmission mode of AI, but autosomal recessive, X-linked can also occur in some cases. AI is a serious condition that can result in reduced oral health-related quality of life and causes some psychological disturbance This article presents a case report of a partially edentulous patient with amelogenesis imperfecta along with its features.

ABSTRACT
Introduction: Dento-maxillary disharmony (DMD), now referred to as Dental Arch Disharmony (DAD), is a highly prevalent anomaly encountered by orthodontists in their daily practice. Objective: The aim of our study is to estimate the prevalence of dento-maxillary disharmony at the dento-facial orthopedics (DFO) department of the Blida University Hospital Center in Algeria, in order to position this disharmony relative to other orthodontic anomalies, estimate its evolution, and compare the results obtained with other studies conducted in different countries. Materials and Methods: This descriptive epidemiological study was conducted at the DFO department of the Ahmed Zabana Dental Clinic at the Blida University Hospital Center, focusing on 80 cases of dento-maxillary disharmony out of 188 cases in the orthodontic population. The study spanned a period of one month and five days, from May to June 2022. Results: Analysis of our records reveals that 42.55% of the orthodontic population exhibits dento-maxillary disharmony, with a predominance of females at a rate of 64%. The most frequent age group is children aged between 6 and 12 years (49%). During our study, the prevalence of relative macrodontia dento-maxillary disharmony was the most dominant, accounting for 86%, followed by 8% for dento-maxillary disharmony due to microdontia, and 6% for mixed cases. Conclusion: The high frequency of dental arch disharmony, as demonstrated in our study and similar studies, emphasizes the need to understand the factors contributing to its development in order to establish prevention and interception strategies, thereby enabling early management of this anomaly.
