Twelve-month evaluation of the atraumatic restorative treatment approach for class III restorations: An interventional study.

BACKGROUNDAtraumatic restorative treatment (ART) may be appropriate for populations without accessibility and affordability. More data are required regarding the success rate of ART in anterior teeth.AIMTo evaluate the clinical performance of restoring class III cavities in anterior teeth of permanent dentition using the ART approach.METHODSA longitudinal interventional field study was carried out at two rural primary health centers, Tumkur district, India. A total of 54 teeth in 39 patients were evaluated for the survival rate of class III restorations in permanent anterior teeth using the ART approach in children and adult populations. Evaluation of ART restoration was carried out using Frencken J criteria, the mean procedure time, patient acceptance and reported pain severity during the ART approach were evaluated using a visual analog scale. Calculation of the cost of ART was also performed.RESULTSThe mean time taken to perform the ART procedure was 14.79 ± 5.8 min with the majority of patients reporting only mild pain. At 6 mo follow-up, 72.2% remained in a good state, but this reduced to 27% at 12 mo. The cumulative survival rate of the restorations was 94.4% at 6 mo and 80.9% at 12 mo follow-up. Estimation of the direct cost for a single class III restoration was 186.50 INR (2.64 USD).CONCLUSIONART may be a good comprehensive option for basic oral health care for underserved or inaccessible populations, and preventive care for patients.

Cleidocranial Dysplasia of a 13-year-old Bangladeshi Girl: A Rare Case Report

Cleidocranial dysplasia (CCD) is an uncommon autosomal inheritant congenital skeletal defect that primarily affects the bones and teeth, and shows an autosomal inheritance. A 13-year-old Bangladeshi girl presented with delayed eruption of the permanent anterior teeth. She was short-statured, well-oriented young girl with narrow, drooped shoulders, malformed or absent clavicles, brachycephalic head with frontal and parietal bossing, hypoplasticzygomatic bones, bulging calvarium, and depressed nasal bridge with a broad alar base. Intraoral examination revealed persistence of the primary dentition, delayed eruption of the permanent teeth, an Angle class III malocclusion, negative overjet, bilateral posterior crossbite. This rarecase of CCD is so far the first case from Bangladesh to be documented in perspective to dental surgery and orthodontics.

Paediatric endodontics. Part. 1: Portland Cements Apical Plug.

Treatment of necrotic immature permanent anterior teeth with Portland cements apical plug. The long-term success of endodontic treatment depends on the quality of the apical and coronal seal. In necrotic immature teeth the treatment can be challenging for the clinician as the endodontic anatomy and the presence of bacterial infection need to be addressed with special techniques and materials in order to obtain an effective and biocompatible apical seal. Unfortunately, despite the best treatments, immature permanent teeth have a reduced resistance to fracture due to the arrest of root walls development.

Prevalence of Dental Trauma and Receipt of Its Treatment among Male School Children in the Eastern Province of Saudi Arabia.

Background Dental trauma is a common dental public health problem, and it affects 20% to 30% of permanent dentition worldwide. Objective To evaluate self-reported dental trauma to permanent anterior teeth and the receipt of dental treatment among male school children. Materials and Methods This cross-sectional study included grade 7 to 9 school children in Dammam/Al-Khobar, the Eastern Province of Saudi Arabia. The participants responded to a pilot-tested self-completion questionnaire which contained questions about experience, types, place, and reasons for dental trauma and the receipt of dental treatment. Bivariate and multiple logistic regression analyses were performed. Results There were 258 students in the study with a mean age of 14.29 ± 1.11 years. Dental trauma was experienced by 39.5% of the participants. Tooth fracture (22.7%) was the most common type of dental trauma followed by tooth displacement (8.7%) and complete tooth removal (8%). The most common reason of dental trauma included fall (9.3%) and accidental hit by some objects (8.9). Home (19.8%), school (5%), and playground (4.2%) were reported as common places of dental trauma. Dental treatment was received by 20.5% of the samples. Most participants visited a dental clinic (10.8%) and used self-care at home (7.2%) after dental trauma. Nearly 4.7% of the participants received dental treatment immediately, 5% on the next day, and 2.7% after a month. Multiple logistic regression analyses showed a significant association of monthly family income (odds ratio = 0.44) with dental trauma (P = 0.008). Conclusion Dental trauma was highly prevalent among school children; however, few of them received care/dental treatment. Participants frequently experienced dental trauma due to a fall in their homes. Preventive measures should be taken to prevent dental trauma, reduce its burden, and improve quality of life.

PREVALENCE AND CAUSES OF TRAUMATIC DENTAL INJURIES TO ANTERIOR TEETH AMONG PRIMARY SCHOOL CHILDREN IN SANA'A CITY, YEMEN

Objectives: The current study was conducted to reveal the prevalence and causes of traumatic dental injuries to permanent anterior teeth among mixed dentition of schoolchildren in Sana'a City, Yemen.
 Methods: A cross-sectional study was performed on 1252 schoolchildren aged 7-12 years in three districts of Sana'a city, Yemen. They numbered 700 males and 552 females from 26 randomly selected public and private schools. Clinical examination of permanent anterior teeth was done according to the classification of Ellis modified by Fried.
 Results: Prevalence of TDI was 10.30%, with a male ratio of 4.8: female 1, (P <0.05). Most of the children suffered only one damage to the tooth and most of them are in the maxillary central incisors. The TDI increased with older age (10-12 years old) (16.5%) with odds ratio 4.8, (p<0.05). Regarding the site of trauma, most injuries happened in males on the street (44.9%) while in females happened at home (31.81%) and falls were the main cause of TDI. In both sexes, the most common type of injury was class I (enamel fracture) followed by class II (enamel and dentine without pulp involvement).
 Conclusion: In conclusion, the prevalence of TDI in permanent anterior teeth among mixed dentition of school children in Sana’a was high, higher in males than in females, with a peak age of 10 to 12 years, falls was the common cause, and occurred mostly on the street for boys and home for females. Accordingly, educational programs should be developed that focus on ways to prevent dental trauma and the benefits of seeking urgent treatment to maintain avulsed and fractured teeth.

 SERO-PREVALENCE OF HEPATITIS C VIRUS AMONG DENTAL CLINIC WORKERS IN SANA’A CITY- YEMEN AND THE RISK FACTORS CONTRIBUTING FOR ITS INFECTION

Adhesion strategy and curing mode of a universal adhesive influence the bonding of dual-cured core build-up resin composite to dentin

To evaluate the influence of different adhesion strategies and curing modes of a universal adhesive on shear bond strength (SBS) of a dual-cured core build-up resin composite to bovine dentin. In total, 60 bovine anterior permanent teeth were randomly divided into 6 groups (n = 10/group) according to; 1: Adhesion strategy, 3 groups (self-etching, etch-and-rinse/wet and etch-and-rinse/dry) and 2: Curing mode, 2 groups (light-curing and dual-curing). Subsequent to root and incisal half removal of each tooth, labial enamel was wet ground over #180 SiC papers, and exposed dentin surface was wet ground over #600 SiC paper for 60 s to create a standardized smear layer. Universal adhesive was applied according to its manufacturer instructions and each tooth was then restored with one dual-cured composite cylinder (2mm×2mm). Shear bond strength was run at a crosshead speed of 0.5 mm/min, and failure modes were categorized into: 1- Adhesive, 2- Mixed and 3- Cohesive failures. Statistical analysis was performed using Two-Way ANOVA/Tukey HSD test. The results showed that factor ‘adhesion strategy’ had no statistically significant effect on SBS (p = 0.525). However, factors ‘curing mode’ and ‘adhesion strategy x curing mode’ showed statistically significant effect on SBS (p = 0.020 and p = 0.002 respectively). Mixed failure represented 55%, followed by adhesive failure (43.3%) and the cohesive failure represented 1.7%. It seemed better to apply the universal adhesive used in this study in etch-and-rinse strategy rather than self-etching one, especially when the adhesive was used in light-curing mode. The use of the DC activator seemed to be unnecessary.

Prevalence of C-Shaped Canals in Anterior and Posterior Teeth of Iranian Population Using Cone Beam Computed Tomography

Background: Lack of knowledge of root anatomy is the second most common reason for failed endodontic therapy. Therefore, acquiring knowledge about it leads to a more effective treatment. C-shaped canal is an anatomical variation that causes clinical challenges. The objective of this study is to determine the occurrence of the C-shaped roots in permanent anterior and posterior teeth of the Iranian population using CBCT (cone beam computed tomography) scans. Methods: This was a descriptive cross-sectional study. In this study, 1408 teeth were assessed. Cranex 3D Mid was used to prepare CBCT images. Each tooth was examined in axial sections, and five different levels were identified as coronal, medium, apical, 1/3, and 2/3. The canal shapes were classified into 5 categories based on modified Melton’s method. Data were analysed using the chi-square test at a significance level of 5%in SPSS version 24.0. Results: In total, of 1408 teeth which were evaluated, 7.81% (110) were confirmed to have C-shaped canals. The occurrence of the C-shaped canal was significantly higher in molars (P < 0.001). The occurrence of the C-shaped canal was significantly higher in mandibular teeth (10.04%) compared to maxillary teeth (5.81%) (P < 0.001). The most common C-shaped canal category was C1 (57.27%). The relationship of gender and age with the C-shaped canal occurrence was not statistically significant (P = 0.585, P = 0.562, respectively). Conclusions: CBCT is a useful tool to evaluate C-shaped root canal morphology. The high occurrence of the C-shaped canal in the Iranian population requires clinical awareness.

Biodentine Pulpotomies on Permanent Traumatized Teeth with Complicated Crown Fractures

IntroductionThe aim of this multicentric prospective study was to evaluate the clinical and radiographic outcomes of Biodentine (BD) pulpotomies on permanent teeth with complicated crown fractures. MethodsThis study was carried out in 2 hospital-based dental departments in Quebec, Canada. Children seeking emergency care after trauma to anterior permanent teeth were invited to participate in this study. The treatment outcome was assessed clinically and radiographically at 1 week and 1, 3, 6, 12, 18, and 24 months after treatment. ResultsForty-five patients between the ages of 8 and 16 years (mean, 10.8 ± 2.4) were included in this study. Fifty-one teeth were treated with a BD pulpotomy. The study showed a survival rate of 100% and a success rate of 91%. Four failures were noted at 1-, 6-, and 15-month follow-up, and the teeth were subsequently treated with either conventional root canal therapy or regenerative endodontic procedure. Dental sensitivity to cold reported by patients reduced over time, and more teeth responded normally to pulp vitality tests during the course of this study. Slight discoloration was noted on 8 teeth (17%). Radiographic outcomes showed dentinal bridge formation in 91% of cases, and all immature teeth showed continued root formation. ConclusionsBD is a suitable material for pulpotomies on anterior permanent teeth with complicated crown fractures. It may be a good alternative to mineral trioxide aggregate pulpotomies because it does not cause significant discoloration, and it allows root maturation.

Spontaneous eruption of impacted maxillary incisors after surgical extraction of supernumerary teeth: a systematic review and meta-analysis.

To evaluate the spontaneous eruption potential of impacted human permanent teeth localized in the anterior part of the maxilla, after the surgical extraction of obstacles in their eruption pathway, by means of a systematic review and meta-analysis. A systematic literature search was carried out to locate studies reporting on the percentage of anterior permanent teeth erupting after surgical removal of the obstacle, without other interventions. Eruption potential of impacted teeth was calculated using a random-effects meta-analysis. Information about the sex proportion, follow-up duration, age and years during which the study was carried out was used for subgroup analyses. A total of twelve studies were included, with a total sample size of 960 cases and a follow-up period of up to 36months. The results show that more than 65.5% of impacted teeth erupt spontaneously following surgical extraction of the obstacle, with an odds ratio of 4 (95% CI 1.9, 8.2) (p < 0.001) favouring spontaneous eruption. When faced with an impacted maxillary anterior tooth, surgical extraction of the obstacle can lead to spontaneous eruption of the impacted tooth in the majority of cases, with better success with a longer follow-up for up to 3years. Based on the present meta-analysis, clinical recommendation would be to surgically remove the obstacle impeding the eruption of a maxillary anterior permanent tooth and wait for the eruption of the tooth for a period of 12-36months, depending on the age of the patient.

The effect of platelet-rich plasma as a scaffold in regeneration/revitalization endodontics of immature permanent teeth assessed using 2-dimensional radiographs and cone beam computed tomography: a randomized controlled trial.

To assess the outcomes of platelet-rich plasma as a scaffold in regenerative/revitalization endodontics (RET) using cone beam computed tomography (CBCT) and 2-dimensional radiographs. Twenty-six healthy patients with mean age of 12.66±4.47, and immature permanent anterior teeth with necrotic pulps, were randomly allocated to two groups, whereby RET was performed using platelet-rich plasma (PRP, test group) and blood clot (BLC, control group). Changes in root length (RL), root dentinal thickness (RDT), apical foramen width (AFW) and radiographic root area (RRA), were assessed using both radiographic methods, whilst changes in periapical area diameter (PAD) were assessed using CBCT, over a period of 12months. T-test and chi-square/Fisher's exact tests were used to compare continuous and categorical data between BLC and PRP groups, respectively. Changes in RL, RDT, AFW, RRA and PAD were examined by comparing the two groups (PRP versus BLC) using multilevel modelling, considering the clustering effect of repeated measures of several teeth originating from the same participant. Changes in RL, RDT, AFW, RRA and PAD, over time, were found to be significant for both groups. There was, however, no difference between the RET techniques (PRP versus BLC), using both radiographic and CBCT methods. The results of both assessment techniques (CBCT and 2-dimensional radiographic methods) were highly consistent (overall ICC ranged between 0.80 and 0.94). In addition, a significant effect of baseline PAD was found on RL, RRA and AD at 12months (RL effect=-0.68, P<0.001; RRA effect=-1.91, P=0.025; AD effect=0.08, P=0.024). The current study highlights successful and comparable clinical and radiographic outcomes of RET techniques using PRP and BLC. Standardized and calibrated 2-dimensional radiographic assessment was as effective as CBCT in assessing RET outcomes; therefore, the routine use of CBCT in RET is not recommended. Although an effect of baseline periapical lesion diameter on root development outcomes, at 12months, were observed, more studies are recommended in order to assess such an effect.

Combined effects of calcium hydroxide and photobiomodulation therapy on apexogenesis of immature permanent teeth in dogs

Treatment of high-risk traumatic immature teeth due to incomplete root development is challenging. Apexogenesis is currently the ideal treatment option that allows normal root development. The purpose of this study was to evaluate the apexogenesis process of immature permanent teeth of dogs when co-administered with calcium hydroxide and photobiomodulation therapy (PBMT). A total of 36 immature permanent anterior and premolar teeth were selected from three 4–6-month-old dogs of Iranian mixed generation. The teeth were categorized into two groups, calcium hydroxide with laser irradiation (CHL) and calcium hydroxide without laser irradiation (CH). All the selected teeth received calcium hydroxide pulpotomy. After restoring teeth with amalgam, the CHL group received gallium‑aluminum-arsenide (GaAlAs) diode laser (810 nm, 4.2 J/cm2, 0.3 W, 9 s,CW) on apical one-third of both buccal and lingual roots. The irradiation was repeated every 48 h for fourteen days. Intravenous tetracycline was used to observe newly formed dentin in the first, third, seventh, and fourteenth days. The distance between tetracycline lines (DTL) was examined by Fluorescence microscopy. Generalized estimating equations (GEE) were used for data analysis. In all assessments, the mean DTL were greater in the CHL group. However, the two groups had no significant differences in the amount of deposited dentin between the first and third, third and seventh, and first and seventh lines. Meanwhile, there was a significant difference between the two groups in terms of the distances between lines 7 and 14, 1 and 14 and also 3 to 14 (P < .001). In other words, from the 7th day onwards, there was a significant difference between the two groups. Within the limitation of this study, the combination therapy of PBMT and pulpotomy with calcium hydroxide accelerated apexogenesis in immature permanent dogs' teeth.

Dental Trauma Experience, Attitudes and Trauma Prevention in 11- to 13-Year-Old Lithuanian Schoolchildren.

To identify the prevalence and determinants of dental trauma in permanent anterior teeth among 11- to 13-year-old schoolchildren, to compare self-reported dental trauma rates with clinical examination trauma rates, and to examine mouthguard use among children engaged in contact sports. A probability sampling scheme was used to recruit schools, with all 6th grade children in the selected schools invited to participate. A total of 2621 caregiver consent forms were sent, of which 807 were returned (31%). Caregivers were asked four trauma-related questions. Clinical examinations included assessment of dental trauma experience (trauma index with five severity codes), lip competence and incisal overjet. Child- and tooth-level analyses were performed. Clinical evidence of dental trauma was found in 52% of participants, 13% self-reported dental trauma, and 7% of children did not remember the occurrence of any trauma. The two most frequently self-reported reasons of dental injury were falls or collisions with objects (63%) and sport/leisure activities (32%). Nearly half of the more severe dental injuries did not receive the necessary treatments. One-third of schoolchildren participated in contact sport activities, but only 3% always used mouthguards. There was a substantial difference between the clinical and self-reported findings. Logistic regression analyses revealed no statistically significant associations between dental trauma experience and the potential determinants studied: gender, lip coverage and overjet. In this study, traumatic dental injuries were observed with 52% prevalence. A substantial discrepancy between self-reported and clinical findings was observed.

A comparison of MTA and Biodentine as medicaments for pulpotomy in traumatized anterior immature permanent teeth: A randomized clinical trial.

The placement of a biocompatible material after performing pulp therapy in traumatically exposed permanent incisors is one of the important factors that determine pulp healing. The aim of this study was to assess the clinical and radiographic outcomes when using mineral trioxide aggregate (MTA) and Biodentine as pulpotomy materials to maintain the vitality of traumatized immature anterior permanent teeth with pulp exposure. Fifty traumatized immature anterior permanent teeth with exposed pulps were included in the study. Teeth were equally divided and randomly assigned to two groups MTA or Biodentine. After pulpotomy, pulp stumps were covered with MTA or Biodentine followed by a permanent restoration. Blinded clinical and radiographic evaluations were performed at baseline, immediate post-operative and after 6, 12 and 18 months according to pre-determined clinical and radiographic criteria. No statistically significant differences were observed between MTA and Biodentine for any of the clinical parameters, except for discoloration, which was significantly more prevalent in the MTA group (P < .001). No significant statistical difference was observed in the radiographic outcomes between MTA and Biodentine, as evidenced by continued root development and by an increased prevalence of root formation stage H in both groups. Both MTA and Biodentine showed similar clinical and radiographic outcomes when used as pulpotomy materials in the treatment of traumatized immature anterior permanent teeth. However, discoloration was significantly more prevalent in the MTA group.

Multidisciplinary Approach to Prosthetic Rehabilitation of Traumatically Lost Mandibular Anterior Teeth using Onlay Graft, Laser and Dental Implants: A Case Report

Traumatic injuries are a primary cause of anterior tooth loss and associated soft and hard tissues damage. Management of lost teeth necessitates a multidisciplinary approach. While the simplest approach in such cases remains that of a Removable Partial Denture (RPD), problems with support and retention can often lead to functional limitations and patient discomfort. Further, patients generally prefer to have a fixed solution over a removable prosthesis. Conventional bridgework also does not provide with suitable replacement in patients with large edentulous spans, thereby, leaving dental implants as the only predictable rehabilitation option. Dental implants present with their own limitations in terms of need for sufficient bone volume for optimum biomechanical foundation for implant placement, adequate space between present teeth and vestibule depth to avoid impingement of the placed implant. This present report illustrates a case of 24-year-old male patient who experienced Road Traffic Accident (RTA) leading to multiple injuries and loss of permanent mandibular anterior teeth. Being dissatisfied with his current removable prosthesis, implant-based treatment was planned. Various clinical findings indicated towards need for onlay grafting and laser assisted periodontal surgery. Thus, a staged multidisciplinary approach was adopted. Postoperative clinical and radiographic findings showed clinically successful treatment. The patient too was satisfied with prosthesis functionality and achieved aesthetics.

Effectiveness of various intracanal medicaments on Candida albicans: An in vitro study

Background: Microbiological studies have shown that Candida albicans is the most commonly found fungi, ranging from 7% to 18% of the root canal infections of tooth. Various intracanal medicaments were analyzed to know the best among them. Objectives: The study objective was to evaluate and compare the antifungal efficacy of various intracanal medicaments, i.e., calcium hydroxide, Odontopaste®, Ledermix® paste, Pulpdent® paste, tri-antibiotic paste, and Coconut® oil cream on C. albicans Materials and Methods: Seventy freshly extracted human permanent maxillary and mandibular anterior teeth extracted for various therapeutic reasons were selected for the study. A standard strain of C. albicans (10,231) was selected and suspended in 20.0 ml of Sabouraud Dextrose broth, and the suspension was adjusted to match the turbidity equivalent to 0.5 McFarland standards. The dentinal blocks were inoculated with C. albicans strains. The seventy dentinal blocks were then divided into seven groups according to the intracanal medicaments used in the study. Each group comprised of ten specimens. Each group was further divided into two subgroups according to the experimental periods, i.e., day 1 and day 7. The data were tabulated and statistically analyzed using nonparametric Wilcoxon signed-rank test and Kruskal–Wallis test to compare the mean and median reduction of C. albicans between intracanal medicaments.

The Apical Extent of Mineral Trioxide Aggregate Apical Barrier Does not Influence the Treatment Outcome in a Nonvital Immature Permanent Anterior Tooth: A Split-Mouth Clinical Study.

Objective:The study aimed to compare treatment outcomes when MTA apical plugs are placed to different apical extents in nonvital immature permanent anterior teeth with an open apex.Methods:Six participants (five male & one female) between the age group of 8-18 years exhibiting bilateral traumatized nonvital immature permanent maxillary anterior teeth (n=12) with non-blunderbuss canal (Cvek’s stage 4) were included. Standardized endodontic procedures were performed, and an inter-appointment calcium hydroxide medicament placed for one week. Based on the apical position of the MTA apical barrier, two study groups were defined. Accordingly, Group I {(n=6) (4mm MTA plug up to the radiographic root end)} and Group II {(n=6) (4 mm MTA plug 2 mm short of the radiographic root-end)}. Teeth were obturated after twenty-four hours with thermoplasticized gutta-percha technique. They were evaluated clinically and radiographically at 12 and 24 months. Radiographs were assessed for periapical healing based on the periapical index (PAI) scores that were dichotomized as score <3 as healed and ≥3 as not healed. The data were compared using Mann Whitney U test, Kruskal Wallis and post hoc analysis.Results:At 24 months, all teeth in Group I and II were healed clinically and radiographically. On inter-group comparison, radiographically, all teeth (n=12) exhibited a PAI score <3 and were categorized as healed (P=1.00).Conclusion:The apical extent of MTA plug does not influence the treatment outcome. The clinician can place MTA apical plug either up to or 2 mm short of the radiographic root-end.

Permanent Anterior Teeth Fractures and its Impact on Oral Health-Related Quality of Life among 8-15-Year-Old Schoolchildren of Chennai City - A Cross-Sectional Survey.

Background:Tooth fracture is not only a distressing experience on the physical level of a child, but it may also have an effect on emotional and psychological levels. This study aims to assess the permanent anterior teeth fractures and their impact on Oral Health-Related Quality of Life (OHRQoL) among 8–15-year-old schoolchildren of Chennai city.Materials and Methods:Thirty schools were randomly selected by stratified random sampling. All school-going children aged 8–15 years were invited to participate. A total of 7247 children were screened and 628 children with permanent anterior teeth fractures were included. Data were collected using Child Oral Health Impact Profile questionnaire. In addition, questionnaire addressing sociodemographic data and factors influencing permanent anterior teeth fractures were recorded. Descriptive statistics was performed to characterize the sample. One-way analysis of variance and Tukey's honestly significant difference post hoc tests was applied for multiple pair-wise comparisons.Results:The prevalence of permanent anterior teeth fracture was found to be 8.7%. The type of school had highly significant (P < 0.001) influence on the impact of permanent anterior teeth fracture on OHRQoL with negative OHRQoL among the corporation schools. The study participants of corporation schools had negative OHRQoL with significant difference in oral health well-being (P < 0.001) and self-image (P = 0.014).Conclusion:All the children reporting with tooth fractures had negative OHRQoL. The study stresses the importance of promoting good oral health-care practices to prevent oral disease in children and to meet children's unmet oral health-care needs.

Surgical-orthodontic therapy of compound odontoma in the anterior maxilla

abstract Odontomas are odontogenic tumors subdivided into complex type (common in the posterior mandible region) and compound type. These lesions are usually asymptomatic and diagnosed in routine examinations, are more frequent in the second decade of life. The objective of this case is to report the treatment of a patient with complex odontoma in childhood in the anterior maxilla. A nine-year-old patient sought dental care due to non-eruption of an anterior permanent tooth. After clinical examination and radiographic analysis, the diagnostic hypothesis of odontoma was confirmed. Surgical removal of the lesion and use of orthodontic appliances were indicated. After the therapeutic protocol, the case was completely resolved. Due to the absence of symptoms, many cases of odontomas are neglected. However, it is evident that the sooner diagnosed, the better the prognosis of the patient.
