The effect of hydroalcoholic extract of Psidium guajava L. on experimentally induced oral mucosal wound in rat.

Background: The aim of this study was to evaluate the biological effects of hydroalcoholic extract of Psidium guajava L leaves and phenytoin as a standard agent on the induced oral mucosal wound.

Methods: Hundred seventy Sprague Dawley rats were grouped in 5 clusters randomly. Oral mucosal wounds were induced in all rats except for the control group.

The Effect of an Educational Intervention on Oral Health Literacy, Knowledge, and Behavior in Iranian Adolescents: A Theory-Based Randomized Controlled Trial.

Introduction: Oral health is one of the most important issues in public health. Most educational interventions, as the primary prevention strategy, are focused on increasing information and knowledge and are not usually effective. Therefore, the present study is aimed at determining the effect of theory-based education on oral health behavior and its psychological determinants including dental health literacy.

The Effect of Toothpastes Containing Natural Ingredients Such As Theobromine and Caffeine on Enamel Microhardness: An In Vitro Study.

The current study aimed to investigate the effect of biocompatible kinds of toothpastes containing natural ingredients such as theobromine and caffeine on the enamel microhardness after demineralization. 72 maxillary premolar teeth extracted for orthodontic purposes were used in this study. Primary enamel surface microhardness examinations were performed using a Digital Micro Vickers Hardness Tester following the Knoop technique (50 g load for 15 s with three indentations at various points).

The effects of lavender aromatherapy on stress and pain perception in children during dental treatment: A randomized clinical trial.

Background And Purpose: Reducing dental anxiety is a major aspect of childmanagement in dental visits. This crossover randomized clinical trial was designed to determine the effect of lavender aromatherapy on anxiety level during dental treatment and pain perception during dental injection in children.

Materials And Methods: Twenty-four children aged 7-9 years received restorative treatment with lavender aromatherapy in the intervention session and without aroma in the control session.

The efficacy of administrating a sweet-tasting solution for reducing the pain related to dental injections in children: A randomized controlled trial.

Background: Anaesthetic injections are an unpleasant experience for children in the dental office. Oral intake of sweet substances by newborns has been shown to be effective in reducing pain.

Aim: The purpose of this study was to determine whether a prior administration of a sweet-tasting solution has an effect on dental injection pain.

Caries Color, Extent, and Preoperative Pain as Predictors of Pulp Status in Primary Teeth.

Aim: This study aimed to assess the relationship between preoperative pain status, caries extent, and caries color and the ability to achieve hemostasis at the canal orifices during pulp therapy access in primary teeth.

Study Design: Eighty primary molar teeth with extremely deep caries extending to the pulp (based on bitewing radiography) were investigated in 66 children. The teeth with clear radiographic and clinical signs indicating the involvement of the radicular pulp were excluded.

Prediction of dental arch width increase in the early mixed dentition using craniofacial parameters.

Background: The dimensions of the dental arch have considerable impact on treatment planning. Since the dental arch development has a relationship with the craniofacial growth, we designed a cohort study to find a regression model for predicting the mandibular arch width increase using craniofacial parameters.

Methods: A total of 148 children, all in early mixed dentition, were selected randomly from primary schools by cluster sampling.

Prediction of the occurrence and severity of mandibular incisor crowding in the early mixed dentition using craniofacial parameters.

Introduction: With the recent interest in esthetics at an early age, prediction of mandibular incisor crowding is of significant importance. Since dental arch development is related to craniofacial growth, we conducted a cohort study to find a regression model for mandibular incisor crowding based on various craniofacial parameters in children.

Methods: A total of 250 children, all in the early mixed dentition, were selected randomly by cluster sampling from primary schools.

Pain Perception Due to Dental Injection by Smartject: Split Mouth Design Study.

Statement Of The Problem: Dental injection is one of the most fearful procedures in dental setting, especially for children. Many researchers have attempted to find a painless method. As computer controlled local anesthesia delivery system devices (CCLADs) allow the speed rate and pressure of injection solution to be controlled, they may cause less pain during injection in comparison to the conventional method.

Bilateral Supernumerary Deciduous Maxillary Lateral Incisors with Fusion: Report of a Rare Case.

Dental anomaly in number, size and shape might be due to excessive activation of dental lamina during the morpho-differentiation stage. Fusion is one of the most unusual and rare anomalies of shape of the teeth. It frequently involves the supernumerary teeth resulting in a challenging differential diagnosis with gemination.

How Do Children Behave Regarding Their Birth Order in Dental Setting?

Statement Of The Problem: Prediction of child cooperation level in dental setting is an important issue for a dentist to select the proper behavior management method. Many psychological studies have emphasized the effect of birth order on patient behavior and personality; however, only a few researches evaluated the effect of birth order on child's behavior in dental setting.

Purpose: This study was designed to evaluate the influence of children ordinal position on their behavior in dental setting.

Clinical Success Rate of Compomer and Amalgam Class II Restorations in First Primary Molars: A Two-year Study.

Background and aims. The majority of failures in Class II amalgam restorations occur in the first primary molar teeth; in addition, use of compomer instead of amalgam for primary molar teeth restorations is a matter of concern. The aim ofthe present study was to compare the success rate of Class II compomer and amalgam restorations in the first primary molars.

Effect of pre-cooling injection site on pain perception in pediatric dentistry: "A randomized clinical trial".

Background: Injection of local anesthesia is one of the most important reasons for development of avoidance behavior in children. Efforts have been performed to decrease pain perception of injection. The present research evaluated the effect of cooling the injection site on pain perception before infiltration of local anesthetics.

Evaluating of life quality in patients with acne vulgaris using generic and specific questionnaires.

Background. Acne vulgaris is a common skin disease that can adversely affect the quality of life of patients. Objective.

MSX1 mutation in witkop syndrome; a case report.

The Witkop syndrome is a rare autosomal dominant disorder characterized by the absence of several teeth and abnormalities of the nails. This is the first report of a rare genetic tooth and nail syndrome diagnosed in a 2.5-year-old boy with early exfoliation of the primary canine, absence of the primary incisors, and nail dysplasia.
