“…This contradicts an earlier study in which canine angulation was found to be significant. 3,15,26 The consensus in the literature confirms that canine angulation does not appear to be related to the prevalence nor the severity of incisor root resorption. 9,[17][18][19]29 The number of females in the present study presenting with impacted canines was more than double that of males but there was no apparent association between gender and the incidence or severity of lateral incisor resorption.…”

“…This is in agreement with several previous studies, 11,24,27 but others have found that resorption occurred most often in the apical third. 25,26 Ethnic variations are said to account for the differences in location of resorption with an Asian population experiencing more apical resorption 25,26 but a Caucasian population showing mid-root damage. 9 In the present study, there was no relationship observed between the incidence and severity of resorption and the site of resorption on the lateral incisor root.…”

“…13 The investigation of several factors has been conducted to assess the risk of canine-induced lateral incisor root resorption. These include gender, 9,11,14,22,23 morphology of the lateral incisor, 9,24 enlarged canine follicles, 9,12,23 the proximity of the canine to the incisor, 9,24,25 the mesiodistal 9,26 and vertical displacement of the canines, 23,25 palatal or buccal impaction, the long axis angulation of the canines to the midline, [27][28][29][30] and the vertical height of the canine measured from the occlusal plane. 24 Two recent studies into severe incisor root resorption concluded that gender and an enlarged dental follicle were associated with an increased risk of lateral incisor resorption related to an impacted maxillary canine.…”

Introduction:The aim of this study was to determine the incidence of lateral incisor root resorption associated with impacted maxillary canines and determine predisposing factors that may be used to predict its occurrence. Methods: Cone beam computerised tomographic images of 133 patients presenting with 186 impacted canines were examined for lateral incisor root resorption. A control sample consisted of 30 lateral incisors on the side of the non-impacted canine. The studied canine-associated variables were gender, type of impaction, location of the canine both meso-distally and vertically and the long axis angulation to the midline. Axial images were primarily used to diagnose resorption. Results: The estimated percentage of lateral root resorption in the sample was 17% (range 11.8-23.9%) confirmed at a 95% confidence interval. A significant association was observed between the level of overlap of the canine across the lateral incisor, measured in sectors, and the probability of lateral incisor root resorption. The probability approximately doubled for each additional sector of canine overlap. No other significant association was noted related to all the other variables examined. Conclusions: The incidence of lateral incisor root resorption associated with impacted maxillary canines was lower in the present study compared with many previous reports. However, resorption remains a common clinical finding. In order to screen for lateral incisor resorption, it is recommended that a cone beam image be prescribed when there is a mesial overlap of an impacted canine across the lateral incisor midline.

“…Attempts to regenerate lost alveolar bone have been elusive, making it a severe hazard to periodontal health. Several factors, including periodontitis, tooth extraction, trauma, orthodontic treatment, and hormone levels, may contribute to alveolar bone loss, among which periodontitis is the most significant pathogenic factor [4][5][6][7][8]. Based on clinical observations, alveolar bone loss can be classified into two main types: vertical bone loss (also called intrabony defect) and horizontal bone loss (also called suprabony defect) [9] (figure 1).…”

Alveolar bone loss is widespread in all age groups and remains a severe hazard to periodontal health. Horizontal alveolar bone loss is the pattern of bone loss more commonly seen in periodontitis. Until now, limited regenerative procedures have been applied to treating horizontal alveolar bone loss in periodontal clinics, making it the least predictable periodontal defect type. This article reviews the literature on recent advances in horizontal alveolar bone regeneration. The biomaterials and clinical and preclinical approaches tested for the regeneration of the horizontal type of alveolar bone are first discussed. Furthermore, current obstacles for horizontal alveolar bone regeneration and future directions in regenerative therapy are presented to provide new ideas for developing an effective multidisciplinary strategy to address the challenge of horizontal alveolar bone loss.

Objective Pre-eruptive intramural resorption (PEIR) is defined as an abnormal, well-circumscribed radiolucency within the coronal dentin of the tooth, which is often overlooked in plain radiographs. This study aimed to investigate the prevalence of PEIR and its related factors using cone-beam computed tomography (CBCT). Methods CBCT images of 590 unerupted teeth were evaluated for the presence of PEIR, location of PEIR, number of lesions in the affected tooth, PEIR score, tooth angulation, tooth position, and pericoronal space. Binary logistic tests were used to analyze the association between the characteristics of PEIR and the patient’s demographic data and related factors. Results The tooth prevalence of PEIR was 13.6% among unerupted teeth. However, it was noteworthy that 19.2% of the unerupted teeth with PEIR were planned to be kept. PEIR was significantly associated with transverse (p = 0.020), inverted-angulated (p = 0.035), and centrally-positioned teeth (p = 0.043). The severity of PEIR was more pronounced in teeth with distal (p = 0.019), lingual (p = 0.023), or inverted-angulated (p = 0.040) positions, and in the absence of pericoronal space (p = 0.036). Conclusion PEIR should be suspected in transverse, inverted-angulated, centrally positioned unerupted teeth, particularly in molars, with no pericoronal space. Further monitoring through CBCT is recommended in such cases. Clinical relevance The management of unerupted teeth does not always involve surgical removal. Instead, they could be utilized for artificial eruption or tooth transplantation. The present study emphasizes the significance of early detection of PEIR. Clinical recommendations for screening PEIR in unerupted teeth are also proposed, which can be applied to routine plain radiographs.
